The Microsoft Standard for GUI design appears to be single-click moves the keyboard caret to the nearest location under the cursor and double-click selects something (e.g. nearest sentence). An optional triple-click selects something more than double-click (e.g. paragraph). The process then cycles between the various effects as you keep clicking. I've never seen a quadruple-click, but, IMO, we probably need one in certain apps. BTW, it is WM_LBUTTONDBLCLK not WM_LBUTTONDBCLICK. Edit controls are hard to master. EN_CHANGE is sent as the user is typing into the edit control but before any visual updates happen. Seems like the wrong notification to look at to me. You are better off waiting for a WM_LBUTTONDBLCLK and then using EM_CHARFROMPOS to determine where the click is occurring within the control. From there, you should be able to select the text you want. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task.
