Randy Birc #3 / 4	from VB file number to VC file handle Hmmm .... as far as I know, there is no way to obtain the real file handle from a VB file number. Your alternative is to use the APIs to open and read the file, which would use a "real" file handle. There may, however, also be other issues with two applications accessing the same file, even if the handle was known. -- Randy Birch MVP Visual Basic Take the vb.net poll at: http://www.mvps.org/vbnet/ http://www.mvps.org/ccrp/ Please respond only to the newsgroups so all can benefit. : Could you kindly help me to associate a VB file number to a VC : file handle?

I assume this is so that VB could open the file, write something to it and then pass things over to a VC function to carry on writing, or something like this? Hmm, interesting question. As other's have said, I don't think it's possible to get the Windows file handle from the VB one so you'll need to use WinAPI call's I'm afraid. Rob.
