Displaying Text

Hello all

Basically, I'm a PHP coder, and I've decided to take have a bash at C. The two languages are so similiar, I think I've pretty much picked it up ok. I can handle command line stuff fine, it's just this stupid windows thing that I can't do.

So, I'm having a bit of a problem with the windows api. I'm just trying to display a window with some text in it...

But the text just doesn't display!! I'm using DrawTextEx()...I would make a guess it's something to do with that. I'm on windows XP, and using CodeBlocks as my compiler.

Here's my code:

Code:

#include <windows.h>

const char Window_Class[] = "WindowClass";

//window callback handler
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
	//switch message...
	switch(msg)
	{
		//close window
		case WM_CLOSE:
            MessageBox(hwnd, "Bye", ":)", 0);
			DestroyWindow(hwnd);
		break;
		//display window
		case WM_PAINT:
            RECT rcClient;
			PAINTSTRUCT ps;
			HDC hdc = BeginPaint(hwnd, &ps);

			DrawTextEx(hdc, "Hello...world?"+'\0', -1, &rcClient, DT_CENTER, NULL);
		break;
		//register window process
		default:
			return DefWindowProc(hwnd, msg, wParam, lParam);
		break;
	}

	return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    char *lpCmdLine, int nCmdShow)
{
	//register windows classes
	WNDCLASSEX  window;
	HWND        hwnd;
	MSG         msg;

	//register window with....windows ;)
	window.cbSize           = sizeof(WNDCLASSEX);
	window.style		    = 0;
	window.lpfnWndProc	    = WndProc;
	window.cbClsExtra	    = 0;
	window.cbWndExtra	    = 0;
	window.hInstance	    = hInstance;
	window.hIcon		    = LoadIcon(NULL, IDI_APPLICATION);
	window.hCursor		    = LoadCursor(NULL, IDC_ARROW);
	window.hbrBackground    = (HBRUSH) (COLOR_WINDOW + 1);
	window.lpszMenuName     = NULL;
	window.lpszClassName    = Window_Class;
	window.hIconSm		    = LoadIcon(NULL, IDI_APPLICATION);

	//...
	RegisterClassEx(&window);

	//create the window
	hwnd = CreateWindowEx(
		WS_EX_CLIENTEDGE,
		Window_Class,
		"Window!",
		WS_OVERLAPPEDWINDOW,
		CW_USEDEFAULT, CW_USEDEFAULT, 500, 250,
		NULL, NULL, hInstance, NULL);

	//run...
	ShowWindow(hwnd, nCmdShow);
	UpdateWindow(hwnd);

	//run the message loop
	while(GetMessage(&msg, NULL, 0, 0) > 0)
	{
		TranslateMessage(&msg);
		DispatchMessage(&msg);
	}

	return msg.wParam;
}

If you need any more info, please ask.
Thanks for taking the time to read this!!

It's been a long time since I've done Windows programming, but I think you need to call EndPaint() after your DrawText call.

No...didn't make a difference unfortunately Still got a blank window...

Thanks for the suggestion anyway.

Any other ideas...?

Aha! After reading a load of MSDN docs, I found TextOut(). Works perfectly. Thanks for your help anyway bithub
