calling formatMessage() from VB5
Posted on 1998-06-21
Hi There !
I using wininet.dll to connect to ftp server, and i want to handle errors, I found that i have to use kernel32.dll formatMessage() (info from MSDN appendix c: handling errors).
That problem is I get "application error" or "mismach type" when I call this func, I belive it's becasue the the last parameter :va_list *args , and in the declaration (from API viewer) it's defined as long.
My questions are :
1. if parameter defined as va_list *Args in the dll - how to I declare it in Vb?
2. how do i send C++'s NULL ? - vbNullString doesn't work
