Introduction
With the introduction of Windows 7 and Office 2010 VBA developers face a new challenge: ensuring their applications work on both 32 bit and 64 bit platforms.
This page is meant to become the first stop for anyone who needs the proper syntax for his API declaration statement in Office VBA.
Many of the declarations were figured out by Charles Williams of www.decisionmodels.com when he created the 64 bit version of our Name Manager.
Links
Of course Microsoft documents how to do this. There is an introductory article on Microsoft MSDN:
Compatibility Between the 32-bit and 64-bit Versions of Office 2010
That article describes the how-to's to properly write the declarations. What is missing is which type declarations go with which API function or sub.
Microsoft has provided an updated version of the Win32API.txt with all proper declarations available for download here:
Office 2010 Help Files: Win32API_PtrSafe with 64-bit Support
When you run the installer after downloading the file form
the link above, it does not tell you where it installed the information.
Look in this -new- folder on your C drive:
C:\Office 2010 Developer Resources\Documents\Office2010Win32API_PtrSafe
You can find a list of the old Win32 API declarations here:
Visual Basic Win32 API Declarations
Microsoft also published a tool to check your code for 64 bit related problems, called the Microsoft Office Code Compatibility inspector addin.
API functions that were added/modified in 64-bit Windows: http://msdn.microsoft.com/en-us/library/aa383663(VS.85).aspx
API Functions by Windows release:
http://msdn.microsoft.com/en-us/library/aa383687(VS.85).aspx

Last, but certainly not least: Dennis Walentin has built an API viewer that is really helpful. You can find the API viewer here.

Which Longs should become LongPtr?
It's actually pretty easy to determine what requires LongPtr and what can stay as Long. The only things that require LongPtr are function arguments or return values that represent addresses in memory. This is because a 64-bit OS has a memory space that is too large to hold in a Long data type variable. Arguments or return values that represent data will still be declared Long even in 64-bit.
The SendMessage API is a good example because it uses both types:
32-bit:
Public Declare
Function SendMessageA Lib "user32"
(ByVal hWnd As
Long, ByVal wMsg
As Long, _
ByVal wParam As Long, lParam As Any) As Long
ByVal wParam As Long, lParam As Any) As Long
64 bit:
Public Declare PtrSafe
Function SendMessageA Lib "user32"
(ByVal hWnd As LongPtr,
ByVal wMsg As
Long, _
ByVal wParam As LongPtr, lParam As Any) As LongPtr
ByVal wParam As LongPtr, lParam As Any) As LongPtr
The first argument -hWnd- is a window handle, which is an address in memory. The return value is a pointer to a function, which is also an address in memory. Both of these must be declared LongPtr in 64-bit VBA. The argument wMsg is used to pass data, so can be Long in both 32-bit and 64-bit.
How to determine what is a memory address and what is data? You just have to read the MSDN documentation for the API functions (the C++ version) and it will tell you. Anything called a handle, pointer, brush or any other object type will require a LongPtr in 64-bit. Anything that is strictly data can stay as Long.
Conditional compiling
If your code needs to run on both 32 bit and 64 bit Excel, then another thing to do is add conditional compilation to your VBA.
Microsoft devised two compile constants to handle this:
VBA7: True if you're using Office 2010, False for older versions
WIN64: True if your Office installation is 64 bit, false for 32 bit.
Since the 64 bit declarations also work on 32 bit Office 2010, all you have to test for is VBA7:
#If VBA7 Then
Private Declare PtrSafe Function GetDeviceCaps Lib "gdi32" (ByVal hDC As LongPtr, ByVal nIndex As Long) As Long
#Else
Private Declare Function GetDeviceCaps Lib "gdi32" (ByVal hDC As Long, ByVal nIndex As Long) As Long
#End If
Private Declare PtrSafe Function GetDeviceCaps Lib "gdi32" (ByVal hDC As LongPtr, ByVal nIndex As Long) As Long
#Else
Private Declare Function GetDeviceCaps Lib "gdi32" (ByVal hDC As Long, ByVal nIndex As Long) As Long
#End If
And then in the routine where this function is put to use:
#If VBA7 Then
Dim hDC As LongPtr
#Else
Dim hDC As Long
#End If
Dim lDotsPerInch As Long
'Get the user's DPI setting
lDotsPerInch = GetDeviceCaps(hDC, LOGPIXELSX)
Dim hDC As LongPtr
#Else
Dim hDC As Long
#End If
Dim lDotsPerInch As Long
'Get the user's DPI setting
lDotsPerInch = GetDeviceCaps(hDC, LOGPIXELSX)
Other API functions
Have a function declaration which is not on this list? I invite you to send me your (working and tested!!!) declarations so I can add them here.
I also welcome comments and suggestions on improvements!

The best way is to find womeone with 64 bit Excel to test this.

Many thanks.

Comment by: Nigel Heffernan (14-11-2014 16:41:48) OpenProcess and GetExitCodeProcess would be useful: both are required for the widely-used ShellAndWait() function.
Note that they are quite tricky: while the handles and pointers are clearly LongPtr in the 64-bit environment, it's not clear whether the Process ID and the exit codes are Long or LongLong integers.

I will surely appreciate all your feedbacks.
Thank you very much.
Comment by: Dan (27-11-2014 13:18:44) Hi,
I need to make my code available to 32-Bit & 64-Bit Excel users, with both VBA7 and earlier verisons.
Can I not just use the
#if VBA7
statement to replace all Long with LongPtr for VBA7 environments? Surely this will just evaluate to long in 32-bit and longlong in 64-bit?
I'm failing to see how this could be detrimental. Why should I be only converting certain Longs to LongPtr?
Any guidance is appreciated.
Comment by: Jan Karel Pieterse (27-11-2014 14:31:29) Hi Dan,
To be honest, I'm not entirely sure what to answer here. My gut feeling says that the arguments you pass to a Win API need to be of the right type. I am not convinced LongPtr would be equally good as Long when the argument is supposed to be a Long. My gut feeling also whispers to me that this is the type of thing that lets vulnerabilities creep into software, but perhaps I'm paranoid :-) .
Comment by: Nigel Heffernan (21-1-2015 18:10:05) Hi Jan -
Thanks for the code for OpenProcess and GetExitCodeProcess.
I notice that you're not using LongLong anywhere in these declarations: do you have examples of Win64 API functions that do require them?
This isn't a matter of idle curiosity: other VBA Gurus are peppering their API declarations with LongLong and I think that they are occasionally wrong - but I think they are safer doing that than taking the risk of receiving a LongLong resource identifier or parameter into a Long integer, and passing the truncated result into another API call. Windows might throw an exception that VBA can handle as an error; it might crash Excel; or it might truncate the value silently and perform some arcane API function on the wrong resource.
Also, there are environments where LongPtr is available, but LongLong isn't.
This means that GetWindowLong isn't the only API declaration that needs three separate segments of conditional compilation; take a look at this, and consider what it means if the only place I can put a breakpoint is
'lParam = 6432'
Public Sub TestEnv()
#If VBA7 And Win64 Then
' 64 bit Excel under 64-bit windows
' We can use LongPtr and LongLong
Dim hWnd As LongPtr
Dim lParam As LongLong
lParam = 6464
#ElseIf VBA7 Then
' 64 bit Excel in all environments
' We can use LongPtr
Dim hWnd As LongPtr
Dim lParam As Long
lParam = 6432
#Else
' 32 bit Excel
' Any length you like, as long as it's Long
Dim hWnd As Long
Dim lParam As Long
lParam = 32
#End If
End Sub
I think we've all underestimated the complexity of the task we face in upgrading VBA code to 64-bit.
Comment by: Nigel Heffernan (21-1-2015 19:41:16) Dan,
You need to do some reading on Pointers, and why 'PtrSafe' matters. Google for 'Dangling Pointer' and see what you get.
What follows is my own understanding, in the language we use as VBA developers; and I am well aware that it contains oversimplifications that push it beyond mere errors and into the logical abyss that philosophers refer to as 'Not Even Wrong'.
A Pointer is the memory address of a resource - maybe the address of the Long integer you're using right now; maybe the address of an object which needs to be in memory when you need it, or a window handle; or, maybe, the address of a function that an API Timer has been told to call in sixty seconds' time.
When that address is incorrect, or when the resource at that address isn't what you expected, things can go badly wrong; so Microsoft have introduced new functions labelled 'Pointer-Safe', which use a special type of integer called 'LongPtr' for memory addresses; and a compiler that reads 'PtrSafe' and 'LongPtr' will create runtime code with new, improved, error-tolerant logic to manage these pointers and the resources in the memory addresses they point to.
You can still store addresses in a LongLong integer: a pointer is just a number. But the compiler won't do that new, improved pointer management on any old integer: you need to declare it as 'LongPtr'.
I do not know what will happen if you declare an everyday integer as a LongPtr, and use it in your code as (say) a loop counter.
My best guess is that things will run very slowly - every time the integer is changed, there will be a series of uneccessary checks to see if there's a memory address with a pointer already using 'your' number - and I would guess that an error-handler (or a complicated redirection and reallocation routine) will be called whenever your integer-declared-as-LngPtr is changed to a value that represents a pointer to memory that's already in use.
Let me know how your application works when you try that.

Wrong, sorry. I think the best bet here is to use Win64 instead of VBA7 and use Alias "GetWindowLongPtrA" and Alias "SetWindowLongPtrA". That is how it is defined in the headers.

I see no obvious reason for the slowness of your code on 64 bit. But you may benefit from turning off screenupdating and calculation when the code starts:
Application.Calculation = xlCalculationManual
'Your code goes here
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
Comment by: Villable (17-8-2010 01:01:53)
Variable 'o' goes from 1 to 20 and variable 'p' goes from 1 to 42. So in 64 bits it takes, at least, AN HOUR while in 32 bits it takes 15 SECONDS!!!
I don't know which is the difference. I think is a bug of Office 2010 64bits, and i'm thinking about install 32 bits to get that problems off.
Thank you anyway.

I'm sorry I can't help you with that on short notice, I'm way too busy to do this for you.
I suggest you to find the information on each of the functions you mention on the Microsoft MSDN site:
http://msdn.microsoft.com/en-us/library/aa383749(v=vs.85).aspx
Like I mentioned above:
Anything called a handle, pointer, brush or any other object type will require a LongPtr in 64-bit. Anything that is strictly data can stay as Long.

Win32API_PtrSafe.txt contains the following:
32-bit (x86) and 64-bit (x64) compatible Declare statements for the Windows API functions that were included in the original Win32API.txt file.
Global constant declarations for the constants that the provided Declare statements use.
Type declarations for the user-defined types (structures) that the provided Declare statements use.

2. Function APR_calc(RIV As Double, Payment_Frequency As Integer, term As Integer, grace_period As Integer, first_pmt As Double, weekly_pmt As Double, final_pmt As Double)
May you please help somehow? Thanks, Martin
Comment by: Jan Karel Pieterse (22-7-2011 07:32:49)
Unfortunately, you cannot use 32 bit controls in 64 bit Office and the Office Web controls are strictly 32 bit.
So you will have to revert to a different method entirely.
If you want to be sure an Excel application works on both 32 and 64 bit, use only the built-in Office controls.
I'm a bit surprised the 1st command does not work, but I strongly suspect this is due to the missing reference.

My client uses Citrix to distribut my MS Access application that uses Windows API declare statements.
The article describes Office 2007 32/64 bit. And most users are probably running from Windows 7. Can you please exapand on a situation for migrating to Windows Server 2008 R2 and the 32 Bit of Office 2010? Is the PrtSafe required for this or could there be other factors?
Moving a working application over to the new server this week, the API functions fail.
New server: Windows Server 2008 R2 Office 2010 32 Bit
The exact same Access code is still working fine on the Windows Server 2003 using Office 2007.

As long as your users are on 32 bit Office your API declarations should work unchanged.
Comment by: Rx_ (3-10-2011 08:02:05)
On a Windows 7 (64 bit) with Office 2010, the error message that the DLL must be updated with PrtSafe is required (as we all expected.
Back at the customer site, the same copy was run on a new Windows 7 Enterprise (32 bit) with Office 2010. It still fails. Setting the MS Access 2010 exe running as administrator in Compatibility Mode for XP sp 3 - it still fails.
Another site recommend checking the Err.LastDllError at various points in the code. And, suggested that there are some DLL for Windows 7 that may have to be upgraded.

The files I tried work on any Office version since Office 97 up to and including 2010.
Are you SURE this isn't a 64 bit version of Excel?
Comment by: Ger (12-10-2011 12:52:57)
My own scenario is: Office 2007 (32 bit), Office 2010 (32 bit) and Office 2010 (64 bit). Code and declarations need to work on all of them.
I cant just use #if VBA7 then use LongLong and LngPtr declarations, because if I do this it will fail to compile on Office 2010 32 bit with a "User Defined Type Not defined" and highlighting the line that contains LongLong
Granted, the compiler statement works fine on Office 2010 64 bit.
The #Else part of the conditional statement catches the compiler for Office 2007 32 bit and there arent any issues there.
But to get declarations to work correct across the three platforms, I believe I need to use the win64 constant, as per the MS 2010 Help file:
' Conditional Compilation Example
#If Vba7 Then
' Code is running in the VBA7 editor.
#If Win64 Then
' Code is running in 64-bit development environment.
#Else
' Code is not running in 64-bit development environment.
#End If
#Else
' Code is not running in the VBA7 editor.
#End If
It makes the declarations awfully long!!!!
Of course, I could be doing something wrong too. :-)
Appreciate the feedback. I can post my current declarations if you wish to see them to cover all 3 platforms (GetActiveWindow, ChooseColorDlg).
Ger
Comment by: Jan Karel Pieterse (12-10-2011 23:48:43)
Thanks for the comments. All declarations shown here should work on those versions, but I guess there may be situations where the win64 compile constant is needed. If you have an example, please post it here and I will include it in the article text!

I advised Ger to replace all LongLong's with LongPtr. Have not heard from him whether that was sufficient.

I'm sorry, but I don't appear to have that dll, so it is not possible for me to answer your question!
NB: if you are on Office 64 bit and the dll is a 32 bit dll, then it will never work.

Comment by: Jan Karel Pieterse (21-11-2011 04:56:46)
Why are you declaring aCustomColors as a Long in the VBA7 case? I'd expect both declares should be of type Byte.
Since I see no differences in the VBA7 case or the Else pare, the entire conditional compilation is not needed?
Comment by: ENZO (21-11-2011 08:35:22)
You are right I've changed type to Long for #VA7
The difference is in function and TYPE CHOOSECOLOR declarations (not wrote above)
here are the two different declarations:
if #Vba7 then
Type CHOOSECOLOR
lStructSize As Long
hWndOwner As LongPtr
hInstance As LongPtr
rgbResult As Long
lpCustColors As LongPtr
flags As Long
lCustData As LongPtr
lpfnHook As LongPtr
lpTemplateName As String
End Type
Declare PtrSafe Function ChooseColor Lib "comdlg32.dll" Alias "ChooseColorA" (pChoosecolor As CHOOSECOLOR) As Long
#else
Type CHOOSECOLOR
lStructSize As Long
hWndOwner As Long
hInstance As Long
rgbResult As Long
lpCustColors As Long
flags As Long
lCustData As Long
lpfnHook As Long
lpTemplateName As String

Look at this page:

It tells us the first two arguments are pointers, so they need to be changes to LongPtr for 64 bit.

I am developping in 32 bit Office 2003 and a number of users run 32 bit office. We now have the first Windows 7 64 bit users and I installed Office 2010 64 bit.
How can I (maybe with a conditional compiler constant, but at least office 2003 does not have eg vba7 or 64bit) continue to develop in 32 bit office, also for use in 64 bit office.
I cannot upgrade to 64 bit myself now.
The easy solution, I believe, would be to install 32 bit office on w7 64 bit, but I like the challenge
Comment by: Jan Karel Pieterse (6-5-2012 11:11:43)
I expect all code that works on 32 bit Office 2010 also to work on 64 bit, except for API declarations. Also, 32 bit ActiveX controls that are not part of Office will not work.
I'd install 32 bit Office and have a virtual machine with 64 bit Office for testing purposes.

I would like to be able to store the PreviousData without having to go to the worksheet cell A1 (or any cell). The data coming in (CurrentData) is from the serial RS232 CommPort. I would like to be able to do this, store the data, perhaps 3,4 times back, i.e.: PreviousData4 without having to store and retrieve from the worksheet. Again, thanks.

Comment by: Peter van Loosbroek (29-6-2012 12:02:47)
The code I used in a standard module in MS Access. In a 32 bit version it works well (of course without using PtrSafe and LongPtr). The function TestGetFile returns the filename. You can test is in the debug window.
I also learned that the VB function Len (in TestGetFile) should be LenB in a 64 bit version.
I hope you can help me (and more people because everyon can use this function).

This means that the Cyberlynx system you refer to is not a 64 bit system and cannot be called from 64 bit Excel.
You must contact the vendor and ask if they have a 64 bit COM enabled version of the system that can be called from Excel VBA.

below is the link to the webpage extension i want to use that requires my excel file to request the appropriate license key through an API from each end user's computer to prevent unauthorized distribution of the file. how do i do this and how do i connect to this api??????
http://wcdocs.woothemes.com/user-guide/extensions/software-add-on/
thanks for your help!
PS. please keep in mind that my file has no macros and what i am trying to protect is the formulas i have built and the data interface i have designed to collect and analyze the data each user would be generating. i built a 40mb file with nothing but formulas and tables, etc....

"Connecting" to this API will require VBA programming.
Unfortunately, the content of Excel workbooks is poorly protected. Anyone can get quick access to your model by running just one simple macro that removes all passwords.
The only way might be to create an on-line version of your model, but that likely requires:
1. An Office 365 subscription (not sure if that suffices)
2. A (possibly drastic) redesign of your model to make it work on-line using the Excel web app.

What code does your Excel fail on?
Comment by: fabrice CONSTANS (4-2-2013 16:42:04)
I have a heterogeneous Park: windows xp, vista, 7 and 8 in 32 or 64 bit Excel 2003 to 2010 in 32 or 64 bit.
What should i use as a compile-time directive? Win64 and vba7, both?
Should I deliver for 2003 to 2007 and 2010 32/64 versions?
My code is :
#If Win64 Then
Private Type structHH_FTS_QUERY
cbStruct As Long
fUniCodeStrings As Long
pszSearchQuery As String
iProximity As Long
fStemmedSearch As Long
fTitleOnly As Long
fExecute As Long
pszWindow As String
End Type
Private Declare PtrSafe Function HtmlHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" _
(ByVal hwndCaller As LongPtr, _
ByVal pszFile As String, _
ByVal uCommand As HH_COMMAND, _
dwData As Any) As LongPtr
#Else
Private Type structHH_FTS_QUERY
cbStruct As Long
fUniCodeStrings As Long
pszSearchQuery As String
iProximity As Long
fStemmedSearch As Long
fTitleOnly As Long
fExecute As Long
pszWindow As String
End Type
Private Declare Function HtmlHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" _
(ByVal hwndCaller As Long, _
ByVal pszFile As String, _
ByVal uCommand As HH_COMMAND, _
dwData As Any) As Long
#End If
Public Sub Show(NewFile As String, Optional WindowPane As String, Optional ContextID)
Dim Fichier As String
Fichier = NewFile
...
#If Win64 Then
Call HtmlHelp(0, Fichier, HH_HELP_CONTEXT, ByVal CLng(ContextID))
#Else
Call HtmlHelp(0, Fichier, HH_HELP_CONTEXT, ByVal CLngLng(ContextID))
#End If
End If
End Sub
Thank you.

As far as I know, VBA7 suffices UNLESS there is a specific API which behaves different on a Win64 machine then on a Win32 machine (e.g. is in a different dll or has a difference in arguments). The ones listed here seem to work just fine with just VBA7.

I am from France, and your article was very usefull for me.
But I did'nt success in declaring the function GetPrivateProfileString in my vba code (access 2010 module under Windows Server 2008)...
I couldn't declare the return value to LongPtr because it made a program crash.
When declaring it to Long, with the key PtrSafe, then I could have the return value (the number of characters read)
But I could'nt retrieve the string read...
Here is my code (not crashing, but not working...) :
Thank you for your feedback.
Best regards

The reason is that the GetPrivateProfileString function returns a Long, not a LongPtr.
So your Dim statement must indeed declare as Long:

I had used the PtrSafe expression below yesterday with great results, but today it no longer works... I am trying to get an calculation box to work. It is labeled as Text227. Yesterday when I used the PtrSafe expression I placed it on the very top line, for example Option PtrSafe Compare Database.
Any ideas?
Thank you for your help!

I see no API declarations in the code you posted?
Comment by: Mireille DOUGUET (13-3-2013 11:27:19)
But the problem is that I can retrieve the number of bytes, ok, but I can't retrieve the string that the GetPrivateProfileString must return to me...
Perhaps the definition of the lpReturnedString parameter, or the way it is passed to the function...
Best regards

You're right of course.
I started building this list and adding Functions as I happen to have the need form them in tools that require porting to 64 bit Office.
As it happens I have not encountered the need to add Sub declarations yet.
As soon as I encounter one (or if you send me some) I'll add them.

Basically, as long as you use the method shown here, you should be fine for older Office versions.
Of course you will have to test your code on all Office versions that it will be used.

Can you perhaps give a more complete example with variable content in place that does work on XP/2003 and returns a proper value? Otherwise this is a bit hard to test.

I tried the MS download but I get a "no result" when searching for this function in VBA help after installing?
I am now looking for URLDownloadToFile. I can not find that by searching the help either.

It is not obvious, but the API declarations are in the txt file.

When looking for 64 bit API calls to manipulate the clipboard I came across this sample:
https://korpling.german.hu-berlin.de/p/projects/excelfalkoplugin/repository/revisions/321/entry/Components/mdlApi.bas
I tested the sample and it functions without error.
It is a 'translation' of the following MSDN example:

Might be useful for your list,
