I have the Developer's Kit and the book << Programmer's Guide to GEM >>
but neither can enlighten me on how to do the following:

1)	How do I get the address of a string contained in a dialog in order
	to change its contents? What I'm doing is:

	:
	rsrc_gaddr( R_STRING, STR_OBJ, &string );
	sprintf( string, "%4d", value );
	:


2)	How do I send myself a WM_REDRAW message? What I'm doing is:

	SendRedraw( tree, obj )
		long tree;
		int obj;
	{
		int msg[8];

		ObjcXywh( tree, obj, &msg[4] );
		msg[0] = WM_REDRAW;
		msg[3] = GemHandle;
		appl_write( ApplHandle, 16, msg );
	}/* SendRedraw */


	someroutine()
	{
		:
		/* dirty screen, change string values in object */
		:
		SendRedraw( TreeObj, ROOT );
	}

Is any of this right?
