Icon?

[prog_tom]

Does anyone know how to change the Icon of the EXE? i mean everytime I compile it, the Icon is the same old DOS ICON

[abdul]

You can load the icon from a resource file and then change the following lines for your window class structure:
(I assume that you have an icon called "THEICONNAME" in the resource file. And I also assume that the window cass structure is declared as wc)

   wc.hIcon = MAKEINTRESOURCE(THEICONNAME);
   wc.hIconSm = MAKEINTRESOURCE(THEICONNAME);

If it's a console app, then just add an icon to the project, and that will be the icon that the EXE will use.

Doesn't work for me

Hi Abdul, I meant the Icon displayed on the EXE file. Not in the program... Also Megatron, I'm creating a Win32 App. Not Console.
Please have a look at this code:

	tz.hIconSm=LoadIcon(NULL,IDI_APPLICATION);
	if(!RegisterClassEx(&tz)){
		return 0;
	}
	hwnd=CreateWindowEx(WS_EX_CLIENTEDGE,tzID,"Welcome!",WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,500,300,NULL,NULL,hInstance,NULL);
	if(hwnd==NULL){
		return 0;
	}
	ShowWindow(hwnd,nCmdShow);
	UpdateWindow(hwnd);
	while(GetMessage(&Msg,NULL,0,0)){
		TranslateMessage(&Msg);
		DispatchMessage(&Msg);
	}
	return Msg.wParam;
}

When I click on the "edit"(TextBox), it pops out MessageBox twice. How to change it to once? Do you know how to get the Text in the "edit"?

it should do it for both, it does for me.

[abdul]

you have

return 0;
break;

at the end of each case statement. Try erasing one of those lines and then see if you get two messages.

Try the following code that shows a messagebox with the editbox text in it:

char edtext[100];
        GetDlgItemText(hwnd, TEX1, edtext, GetWindowTextLength(GetDlgItem(hwnd, TEX1)) + 1);
        MessageBox(NULL,edtext,"The text",MB_OK);

Yes

[prog_tom]

Yeah I removed:

return 0;
break;

But each time I clicked Either Button or Edit, it will pop up expressions for both.
I only want like one for one...

[abdul]

that is wierd. I only get two message boxes with the editbox. I don't know if there is any other way to do so without subclassing the editbox. I think that you are getting two message boxes because of one "Down" and one "Up" event on the editbox.

Here is the subclassing thing that only shows one messagebox when the mouse is down:
