Okay so.. I have this SDI and I know even is not a good design, but I want to understand how do I close the function 'Void CheckBox1()' after I enable it in WM_COMMAND, cause I tried different things like WM_DESTROY, or WM_CLOSE but without success.. I know that these cases take no action for static controls but how do I do that?
I put the entire code here and no worry about the resources is only the background I change it.. it should work fine.
Mif (403)
Ohh forgot to say the function void CheckBox1() should be close from the button Close.. that will appear when you click on the Characters button..

Try DestroyWindow(hChBox) on the Close button message.
I am not 100% if this is the best way.
Is there a reason why you don't use a normal Windows dialog?

            default:
                return DefWindowProcW(hWnd, msg, wp, lp);
            }


The Problem is I had to send message to all the static that is in the function void hCheckBox()...
Mif (403)
Anyone knows a better method to do this, maybe not that long.. ?
Mif (403)
Or maybe is there a way to press again the same Button Characters to destroy the void function? Like this I could get rid of the Close button..
MikeyBoy (5631)
to destroy the void function

What on earth do you mean by that? What even is destroying a function?
Mif (403)
I meant to disable it like you do with

 
 
EnableWindow(hWnd, false);

This is where I asked if there's another way do this (destroy the void)meaning by using a WM_DESTROY .. :)

It's only an expression saying destroy a function

But... what do you mean by that? You can't destroy a function! Can you explain more clearly what it is you think you mean by that expression?
