Windows 95 used 16-bit API calls. Win98 could handle those or 32 bit
calls. Win NT and up only handle the 32-bit calls and the names of some
of the libraries and the types of some of the arguments are different.

Subject: RE: [AccessD] WindowsXP not recognizing ape Call
Connie,
I use the code I downloaded from Candace Tripp's website for this. It's
been a while, but I remember that she has separate downloads for these
operating systems, and that the code is slightly different, although I
didn't understand the differences. I use the code as is on Windows XP
PC's, and it works.
Look at www.candace-tripp.com.
Good Luck!
Dan Waters

Subject: [AccessD] WindowsXP not recognising api Call
Ok further to last week I have been trying to find the problem with my
inherited app. The api call works fine on windows98 and when taken to
windows XP machines does not work. It throws no errors just does not
open the Windows Open Save dialog box. The code is word for word to the
Getz API call but when the XP machine reaches the If OpenFile Then
fResult = adh_apiGetOpenFileName(OFN)
Else
fResult = adh_apiGetSaveFileName(OFN)
End If
It does not open the dialogue box. Running the same code side by side on
the win98 machine I get the popup box every time. I have run a reference
checker and it says all references are OK. The code is below if that
helps.
