Got some legacy Delphi 5 code.
In the initialization of one of the unit there is code to validate the
version of a DLL. If the DLL is not the right version, an error message
is displayed using:
MessageBox( GetStdHandle(STD_OUTPUT_HANDLE), pchar('error..') ,
MB_ICONERROR+ MB_OK );
One of my customer reported he had the error message under Citrix.
I replicated its configuration on my XP machine. I dont have the error
message, if I double-click on the executable. I start my application
using the Delphi debugger, the error message is displayed?
Why does MessageBox() display nothing if I start the EXE, and display
something in the Delphi IDE. Could this explain the Citrix reaction ?
Thanks
