Re^3: Win32::API - How to call an Imported function with Win32::API::Types ?

I suspect that the problem is that TCHAR is not a type that Win32::API::Type knows about. You can find the list of those that it does know about at the bottom of the Type.pm source file.

You probably need to change

Win32::API::Type->typedef( 'OMDTEXTZ', 'TCHAR');

to something like

Win32::API::Type->typedef( 'OMDTEXTZ', 'unsigned char')
    or die $^E;
[download]

However, if you were to add some error checking to your calls (as above and in my original snippet. E.g. ...or die $^E;), then the module would be telling you what is wrong and where.

According to the source, `TCHAR` is a valid type which is why I chose it. Hmm... As you suggest, I shall put lots of error checking in and see what isn't being liked. Thanks, fx, Infinity is Colourless	[reply] [d/l]

Ok, I've just added `...or die $^E` to every Win32::API module call and nothing is `die`'ing. As far as I can see the call to the function inside the DLL is actually working Hmm... fx, Infinity is Colourless	[reply] [d/l] [select]

Try initializing `my $client = pack('L', 0);` as you did in the code that worked. Examine what is said, not who speaks.
