Hi,

I have a simple VCL test app that is a form with a button, the button
OnClick calls a function in a DLL (DLL created in Visual Studio 2005 -
C++ - have full source).

It works perfectly on XP, press the button and the function gets
called...  I have a very simple unit that is the interface to the DLL
function e.g.

procedure AS1(text:PChar; f, f2:Integer); cdecl; external 'MYDLL.dll';

In Vista, when running the same app, not even the form appears.  The
app is in the the list of processes but nothing happens.  Have tried
it on a few Vista boxes and always the same result.  It looks like the
DLL cannot be loaded for some reason.  I tested another VCL app that
does not use a DLL (identical except instead of the function in the
DLL I did a call ShowMessage just as a test) and it works fine on
Vista.

Any one have any ideas what the problem might be and how to resolve
it?

TIA,

P.
