Question

i am learning win32 api . i know how to add pushbutton on the fly. now i am trying to add a pushbutton using a resource file ( rse.rc ) . below is my res.rc file defination:

IDB_B1 PUSHBUTTON "TOGGLE",7 , 20, 180, 200, 30

and i have evn generated a resource.h file to be included in the source. now the problem i am facing is how di add this button to my main window ? i have tried adding cursor and icon using .rc file which is easy but can not get my head around this button .

i guess it has to be under:

WM_CREATE:

but how exactly to call it from .rc file?

Answer 1

It does not work this way.

Resources in Win32 are used to create many things: menus, accelerators and dialogs, among others; but not single controls.

What you want to do, a main window with a button can be achieved using two techniques:

1. Let your main window be a dialog. You write the resource for a full dialog, with buttons and all, and from WinMain() you call CreateDialog() . DialogBox() or similar.
2. Your main window is a normal window, and you create child contros manually. These controls are created calling CreateWindowEx() directly, with class name WC_BUTTON , as a response to WM_CREATE as you guessed.

Also, you can make the dialog a child of the main window, but I don't recommend that, specially if you are still learning.
