The tricky part is getting the toolbar buttons to line up with the arbitrary widget: You add a separator to the toolbar of the width that you want your widget to be, and in the location that you it to be. You then create whatever widget you like, setting its parent window to be the toolbar, and its bounds to be the bounds of the separator. Given toolbar handle "bar" the following creates a text box inside a toolbar: (translated from pascal in my head, so it probably doesn't compile) TBBUTTON tb; RECT r; int i; tb.iBitmap = 100; // The width goes in the bitmap field. // Of course! It's so obvious! tb.idCommand = 123; tb.fsState = 0; tb.fsStyle = TBSTYLE_SEP; tb.dwData = 0; tb.iString = 0; SendMessage(bar, TB_ADDBUTTONS, 1, &tb); i = SendMessage(bar, TB_COMMANDTOINDEX, 123, 0); SendMessage(bar, TB_GETITEMRECT, i, &r); h = CreateWindow('EDIT','Foobar', WS_CHILD | WS_VISIBLE | WS_BORDER, r.left, r.top, r.right - r.left, r.bottom - r.top, bar, 0, instance, NULL); The only hard part after this is to catch any button order updates, and change the bounds of the widget so that it stays "on top of" the separator. A smart programmer (unlike me) would store the handle in the dwData field (or in a structure pointed to by the dwData field) for easy reference. -Jim
