    Text being automatically selected: WM_SETTEXT

    Hi,

    This strikes me as pretty silly, but I can't figure out why this is happening.

    I've got the following code (in highly cut-down form):

    Code:
    LRESULT CALLBACK HelpAboutDlgBox(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
    {
    	static char outbuf[UV_MAXANALEN];
    	static HWND help_abt;
    
    	switch (message)
    	{
    		/* Use messages to update, etc */
    		case WM_INITDIALOG:
    			help_abt = GetDlgItem(hDlg, HELP_ABT); // Multiline edit area
    			strcpy(outbuf, "A lot of text");
    			SendMessage(help_abt, WM_SETTEXT, (WPARAM)NULL, (LPARAM)outbuf);
    			return TRUE;
    			break;
    		case WM_COMMAND:
    			...
    			break;
    		default:
    			break;
    	}
    	return FALSE;
    }
    For some reason, the text when displayed is being selected (as if with Control-A) and yet I'm doing nothing to achieve this. The effect is undesired.

    HELP_ABT is defined as follows:
    Code:
    EDITTEXT        HELP_ABT, 32, 23, 293, 102, ES_MULTILINE | ES_READONLY | WS_VSCROLL
    Is there anything wrong with the above code fragment that would give rise to this?

    TIA!

    Return FALSE from WM_INITDIALOG instead of TRUE.

    Thanks Bithub, that worked a treat :-)

    Funnily enough, I'd tried that (amongst lots of other things) before posting, all to no effect.
