I know how to create multiple ones... but it just isn't efficent. Let's say I have res file with 2 dialog windows. I load the dialog with control ID 100, later I want to also load the one with control id 200... ( like let's say an about window). How could I do that without callind dialogboxparam and all that crap again.

Create an array with contol ID values, then make a loop that retrieves values from this array and calls DialogBoxParam.

What is it that you have against calling DialogBoxParam twice?

You don't need a message loop at all for DialogBoxParam... its is a modal window (the function returns when the dialog box is closed)

And you can always point to the same DlgProc (message handling) for all your windows. But then you must remember that ids have to be different in every window.

HMMMMM..... You just gave me a good idea Reverend... I'll have to use polymorphism.

So,Instead of having to make a whole new loop to handle the new window. I'll use polymorphism to do changes the the current loop, to increase performance.

Nice but rather error-prone solution Wink

I'd rather suggest sth like this:

Code:

; let's say we have two dialogs of ids 1 and 2
; both have two buttons (100, 101) and (200, 201)

proc DlgProc hwnd, umsg, wparam, lparam
        cmp [umsg], WM_INITDIALOG
        jz ...
        cmp [umsg], WM_CLOSE
        jz ...
        cmp [umsg], WM_COMMAND
        jnz @F
        cmp [wparam], 100
        jz ...
        cmp [wparam], 101
        jz ...
        cmp [wparam], 200
        jz ...
        cmp [wparam], 201
        jz ...
    @@:
endp

You see there's no need for any polymorphism. Just some code is shared between dialogs, but they still can be distinguished (100-199 first dialog, 200-299 second dialog)
