[fpc-pascal]Need Windows Dialog Help

[Matt Emson]

If you want to create a dialog (i.e. traditional windows dialog) you'll need
to create a resource file containing the windows resource information.. I believe
it is possible to do this programatically, but I don't know how easy it is to
do so. There is then a load of win32 API that handles the creation and displaying
of Dialogs. (take a look at CreateDialog for a starter..)

If you mean just a traditional main window.. Have a look at the examples that
come with Borland Pascal/ Turbo pascal for windows (if you still have them.)
Failing that, CreateWindow and CreateWindowEX are good starting points. If you
can read C code, there are some resources out there..

You can probably also just create another window.. in the same way as below.


Hope that helps (and isn't off at a tangent)
