PNG As Window/Region?

[Hyperlisk]

Hi, I was wondering if anyone has any code they could share that demonstrates how to use a png image as a window. I have no idea where to start... I assume Either GDI+ or pnglib, but that's about it...

But yeah... If anyone has anything they can share, I would be delighted to look at it. Hopefully in C/C++ or MASM, but I'm sure anything will be fine if I can adapt it.

Thanks,

Here's a small C snippet using pnglib, pretty straight forward really:

#include <windows.h>
#include <commctrl.h>
#include "resource.h"
#include "pnglib.h"// Prototypes
INT_PTR CALLBACK Messagehandler(HWND, UINT, WPARAM, LPARAM);// Global vars
HINSTANCE Instance;PNGINFO PNGMain;
HBITMAP BmpMain;
BITMAP BmpDimensions;// ---int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow)
{
	Instance = hInstance;
	InitCommonControls();	DialogBox(Instance, MAKEINTRESOURCE(IDD_MAIN), 0, &Messagehandler);
	ExitProcess(NULL);
}INT_PTR CALLBACK Messagehandler(HWND Window, UINT Message, WPARAM wParam, LPARAM lParam)
{
	switch(Message)
	{
		case WM_INITDIALOG:
			// Load background png
			PNG_Init(&PNGMain);
			PNG_LoadResource(&PNGMain, Instance, MAKEINTRESOURCE(PNG_MAIN));
			PNG_Decode(&PNGMain);
			BmpMain  = PNG_CreateBitmap(&PNGMain, Window, PNG_OUTF_AUTO, false);
			GetObject(BmpMain, sizeof(BmpDimensions), &BmpDimensions);
			break;		case WM_PAINT:
			PAINTSTRUCT ps;
			HDC hdc, hdcMem;			hdc = BeginPaint(Window, &ps);
			hdcMem = CreateCompatibleDC(hdc);			SelectObject(hdcMem, BmpMain);
			BitBlt(hdc, 0, 0, BmpDimensions.bmWidth, BmpDimensions.bmHeight, hdcMem, 0, 0, SRCCOPY);			DeleteDC(hdcMem);
			EndPaint(Window, &ps);
			break;		case WM_CLOSE:
			EndDialog(Window, 0);
			break;		case WM_DESTROY:
			DeleteObject(BmpMain);
			PNG_Cleanup(&PNGMain);
			break;		default:
			return false;
	}	return true;
}

I removed some stuff to make it a more basic example, there might be an error two, haven't run it through a compiler :>

My lib patchLib does this as well if you want to take a look at it's code to see how I did it. You can find it here:
