Getting Windows Directory

Getting Windows Directory

Question:
How do I determine the Windows directory?

Answer:
The API call to use is “GetWindowsDirectory”. The Declare statement is listed in the the Windows 3.1 API help and the documentation is in Windows 3.1 SDK help file. Note: for VB4, obtain the API declaration from the API Text Viewer.

To use, do the following:

Dim buffer as String * 128Dim size as IntegerDim retval as Integerbuffer = space$(128)size = 128retval = GetWindowsDirectory(ByVal buffer, ByVal size)

When the subroutine executes, the Windows directory will be located in the string named “buffer”. The “buffer” variable MUST be declared with a size, so use Space$(128) as a safety precaution. Since VB does not use null-terminated strings, the size value tells it how big the buffer is. If you do not do this, your program will crash.
