Thread: how to use the constants in afxres.h

Hi,can someone help? I am aware that many constants like ID_FILE_NEW is defined in "afxres.h". I tried to use ID_FILE_NEW constant in my menu, but it came out with the error shown below.

Code:

Deleting intermediate files and output files for project 'xWrite - Win32 Debug'.

--------------------Configuration: xWrite - Win32 Debug--------------------

I am using VC++. Here is my resource.h and resource.rc:

Using the ID_FILE_NEW in this function call in a wndProc where WM_COMMAND is received:

Code:

void mainFrame::mainWindow_onCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify)
{

	switch(id)
	{case ID_FILE_EXIT:	DestroyWindow(hwnd);
						break;
	case ID_FILE_NEW: Edit_SetText(hEditCntl,NULL);
		              break;  
	default: FORWARD_WM_COMMAND(hwnd,id,hwndCtl,codeNotify,DefWindowProc);
	}

}

Thanks it worked
