Thread: How do I update an edit box?

Well so why this dosen't work? It compiles and starts but the dialog dosen't show up...

Code:

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include "clock.h"

SYSTEMTIME time;
char strtime[20];

BOOL CALLBACK DlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
    switch(Message)
    {
        case WM_INITDIALOG:
            while(1)
            {
                GetLocalTime(&time);
                sprintf(strtime, "%d:%d:%d", time.wHour, time.wMinute, time.wSecond);
		SetDlgItemText(hwnd, IDC_TIME, strtime);
            }
	break;
        case WM_COMMAND:
        break;
        case WM_CLOSE:
             EndDialog(hwnd, 0);
        break;
	default:
	    return FALSE;
    }
    return TRUE;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
	LPSTR lpCmdLine, int nCmdShow)
{
	return DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, DlgProc);
}
