in C, you can declare a sexy function like this:

Code:

HWND roflWindow = FindWindow()

then everyone can use it, how can i do it in delphi ?

i tried with type/const, thanks !!

i showed an example, -_-

look, in C you can do it like this:

Code:

#include <windows.h>

HWND dd = FindWindow(NULL, L"Calc");

void main()
{
if(dd != NULL)
//your code
}

how can i do it in Delphi ?

I don't think you can initialize variables outside the code, you can just initialize them in Form_Create.

Delphi has initialization and finalization sections.

If your unit needs to perform any cleanup when the application terminates, such as freeing any resources allocated in the initialization part; you can add a finalization section to your unit. The finalization section comes after the initialization section, but before the final end.

Read before you ask please.
