Borland C++ 4.5 and 5.5?

[Vladimir Perkic]

Hi everybody!

Does anybody know why Borland C++ 5.5 reports errors at line:

CreateWindow ("button", "One",
WS_CHILD| WS_VISIBLE| BS_PUSHBUTTON,
20, 8, 75, 25, hwnd, (HMENU)IDBT_ONE, hInst, NULL);

error is at '(HMENU)IDBT_ONE': cannot convert 'void *' to
'HINSTANCE__ *'...
Borland C++ 4.5 compile this code without any errors or warnings.

Thank you in advance

Possibly, because you "cannot convert 'void *' to 'HINSTANCE__ *'".

Since HINSTANCE__ is undefined in the C standard, you'll need
show us how you defined it, or take it to some newsgroup that
might actually be appropriate for that type of question.

HInstance is supposed to be an unsigned int but Borland (contrary to their
help file) has defined it
as a void*. Do reinterpret_cast<unsigned> (HInstance)...
