in a readerDeclaring API functions in 64 bit Office
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
Utter Access API declarations (a comprehensive list of many declarations)
Last, but certainly not least: Dennis Walentin has built an API viewer that is really helpful. You can find the API viewer here.
Declarations by API function
Function name
Declarations (Declarations which contain the keyword
PtrSafe are 64 bit, without the keyword are 64 bit)
Declare PtrSafe Function
CloseClipboard Lib "User32" ()
As LongPtr
Declare Function CloseClipboard Lib "User32" () As Long
Declare Function CloseClipboard Lib "User32" () As Long
This is a complicated one because it has a lot of arguments.
A fully functional example is included below the example declaration
lines.

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!

I agree the table caption is confusing as I have not been consistent in the order of the declarations. I have updated the column title accordingly :-)
