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.
