I am trying to obtain the version number of my VFP 5.0 EXE. I've got everything working except the most importand of the three API calls. Here's what I got going so far:
DECLARE INTEGER GetFileVersionInfoSize in VERSION.DLL ;
	String, Integer @
DECLARE INTEGER GetFileVersionInfo in VERSION.DLL ;
	String, Integer, Integer, String @
DECLARE INTEGER VerQueryValue in VERSION.DLL ;
	String, String, String @, Integer @

cFileName='N:\LIMS\lims.exe'
nJunk=0
nFVS=GetFileVersionInfoSize(cFileName,@nJunk)

cVersionData=space(nFVS)
rv=GetFileVersionInfo(cFileName, nJunk, nFVS, @cVersionData)

cVersion="             "
nValLen=0
rv=VerQueryValue(cVersionData, "\StringFileInfo\040904E4\FileVersion", @cVersion, @ValLen)
The nValLen contains the correct length of the return value, but the return value is just junk. I displayed the cVersionData to the screen and could decipher the items in the unicode output. The only thing I can figure is I'm not ueing the correct lang-charset mentioned in the help topic for this function (GetFileVersionInfo). You'll notice I'm just using the example from the help file. Anyone been able to pull this off? Do I need to convert the result of the GetFileVersionInfo function back to a normal string (since it's unicode?).

Thanks

Steve
