Method signatures and required data structures.

The module can contain all declarations and dependencies: It is recommended to create a dedicated API module to provide easy access to the system functions from VBA wrappers - normal VBA Subs or Functions that encapsulate the details needed for the actual system call such as parameters used in libraries, and initialization of those parameters 'Immediate window result: Paused for 9.000 seconds Sleep 9000 'Pause execution for 9 secondsĭebug.Print "Paused for " & Format(Timer - start, "#,#.000") & " seconds" Simple example for the Sleep API call: Public Sub TestPause()

DLL procedures declared in any other type of module are private to that module.

To declare a procedure private to a module precede the declaration with the Private keyword.

Procedures declared in standard modules are public by default.

Declarations are placed at the top of the module, and outside any Subs or Functions.

The main difference when declaring APIs is between 32 bit and 64 bit Office versions which introduced new parameter types (see Remarks section for more details) For example Win32 = TRUE in 32-bit Office, even if the OS is a 64-bit version of Windows. These constants refer to the Office version, not the Windows version. Note that Vba7 was introduced alongside Office 2010 to support 64 bit versions of Office. Which ones exist will depend on the bitness of the office version you're running VBA in. Some compilation constants are already pre-defined. Win64 and Win32 are predefined constants used for conditional compilation The above declaration tells VBA how to call the function "Sleep" defined in file Kernel32.dll Private Declare Sub apiSleep Lib "Kernel32" Alias "Sleep" (ByVal dwMilliseconds As Long) Private Declare PtrSafe Sub xLib "Kernel32" Alias "Sleep" (ByVal dwMilliseconds As Long)
