Declaring DLL functions in WIN98 and WIN2000
Dear All,
I have a module which contains reference to DLL functions and subs. The problem is that my program should be used under WIN98 as well as WIN2000, the problem is the DLL exists in C:\windows\system when it is in WIN98 and C:\WINNT\system32 in WIN2000. I would like to declare the path of the function depending on the version of windows I am using.
Your help is appreciated.

Not at all, Angel is correct. If you install that dll with an installer, the install program should knows where is located the system directory for each windows version.

What happened if the files do not exist in the system directory, I am aware of the common path specified of windows but I need to have control over the declaration path.
You simply have to ensure that the dll is in the "PATH" (or in the application folder itself), otherwise you have to use LoadLibrary API, while then you cannot DECLARE the function as such.

If it is in the system folder as described then there is no need to declare the path to it as this is automatically assumed.

Can you use the API calls to get the Windows & System directories?
Declare Function GetWindowsDirectory Lib "kernel32" _
Alias "GetWindowsDirectoryA" (ByVal lpBuffer As String, _
ByVal nSize As Long) As Long
Declare Function GetSystemDirectory Lib "kernel32" Alias _
"GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long
Eg:
Dim sBuffer As String
Dim iReturn_Value As Long
sBuffer = String$(200, " ")
iReturn_Value = GetWindowsDirectory(sBuffe r, 200)
Declare Function GetWindowsDirectory Lib "kernel32" _
Alias "GetWindowsDirectoryA" (ByVal lpBuffer As String, _
ByVal nSize As Long) As Long
Declare Function GetSystemDirectory Lib "kernel32" Alias _
"GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long
Eg:
Dim sBuffer As String
Dim iReturn_Value As Long
sBuffer = String$(200, " ")
iReturn_Value = GetWindowsDirectory(sBuffe
"C" grade!, Why?

Simply because you were the first to answer but not quite what I want.. I was aware of the PATH issue and hence nothing was added to my knowledge, I guess "C" in this situation might have been adequate for just taking an effort.
Cheers.
