Thread: Colouring Edit Box Child Windows

Also, if your interested in fancy edit boxes, then its probably time for you to look at rich edits....Ken's site has info...here's a basic one

Code:

#include <windows.h>
#include <tchar.h>
#include <richedit.h>

LRESULT CALLBACK WndProc(HWND hWnd, 
						 UINT msg, 
						 WPARAM wParam, 
						 LPARAM lParam)
{

	static HWND hEdWnd;
	const COLORREF col = 0x00FF8800;//Half green,full blue
	RECT rect;


 	switch(msg){
	case WM_CREATE:

		GetClientRect(hWnd,&rect);
		

		hEdWnd = CreateWindow(RICHEDIT_CLASS,
							  NULL,
							  WS_CHILD | WS_VISIBLE | ES_MULTILINE,
							  rect.left,
							  rect.top,
							  rect.right,
							  rect.bottom,
							  hWnd,
							  NULL,
						      GetModuleHandle(NULL),
							  NULL);
		SendMessage(hEdWnd,
					EM_SETBKGNDCOLOR,
					0,
					(LPARAM)col);

	
		break;
	case WM_CLOSE:
		PostQuitMessage(0);
		break;
	default:
		return DefWindowProc(hWnd, msg, wParam, lParam);
	}

	return 0;
}

int WINAPI WinMain(HINSTANCE hInst,
				   HINSTANCE,LPSTR,int nShow){

	TCHAR szWindowName[]= _T("ColourEdit");
	WNDCLASSEX wc= {0};
	HWND hWnd;
	MSG msg;

	HMODULE hMod = LoadLibrary(_T("riched20.DLL")); //Need this!!
	if(!hMod) {
		return EXIT_FAILURE; 
	}

	wc.cbSize= sizeof(WNDCLASSEX);
	wc.style= CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS;
	wc.lpfnWndProc= WndProc;
	wc.hInstance= hInst;
	wc.hIcon= LoadIcon(NULL, IDI_WINLOGO);
	wc.hCursor= LoadCursor(NULL,IDC_ARROW);
	wc.lpszClassName= szWindowName;
	wc.hbrBackground= CreateSolidBrush(RGB(255, 255, 255));
	wc.hIconSm= LoadIcon(NULL, IDI_WINLOGO);

	if(!RegisterClassEx(&wc))return EXIT_FAILURE;

	hWnd= CreateWindowEx(WS_EX_CLIENTEDGE | WS_EX_ACCEPTFILES,
						   szWindowName, 
						   szWindowName, 
						   WS_OVERLAPPEDWINDOW,
						   CW_USEDEFAULT, 
						   CW_USEDEFAULT, 
						   400, 
						   400, 
						   HWND_DESKTOP, 
						   NULL, 
						   hInst, 
						   NULL);
	if(!hWnd) {
		return EXIT_FAILURE; 
	}

	ShowWindow(hWnd, nShow);
	UpdateWindow(hWnd);

	while(GetMessage(&msg, NULL, 0, 0) > 0)
	{
		TranslateMessage(&msg);
		DispatchMessage(&msg);
	}

	FreeLibrary(hMod);

	return msg.wParam;
		
	return 0;
}
