Defining IDs

I don't think this has happened to me before. I was defining a few IDs for some buttons and Edit boxes I was going to use and it comes up with this error when I try to compile:

Code:

35 c:\windows\profiles\hpuser~1\desktop\login.cpp
 passing `int' to argument 10 of `CreateWindowExA(long unsigned int, const CHAR *, const CHAR *, long unsigned int, int, int, int, int, HWND__ *, HMENU__ *, HINSTANCE__ *, void *)' lacks a cast

If it can't be defined as an integer what can it be defined as? The only value that works is 0, but you can't define more than one thing as the same value. This is probably a simple question. Thanks.

Try casting it to a HMENU.

Something like

Code:

(HMENU) BUTTON_ID

It lets me define and apply that ID to the button, in the CreateWindowEx function, but then I wrote this code to make it does something:

Code:

case WM_COMMAND:
switch(HIWORD(wParam))
{
case ID_BUTTON:
//code to execute when clicked
break;
}
return 0;

It's saying the ID needs to be an integer to use the WM_COMMAND on it. Do I need to write a whole different window processing function to make it receive messages telling the window it has been clicked? Thanks for answering me, Dante Shamest.

Use LOWORD(wParam), not HIWORD(wParam).
