The usual examples given in introductory textbooks (with one But the importantįeature of both these techniques is that the control manipulation code exists In my solution, all the code is in one function.
ON_UPDATE_COMMAND_UI handler, and the code to enable the control goes in that Only difference between the technique I'm about to describe and the technique heĭescribes is how the code is partitioned. WM_KICKIDLE and looking at the C++ Q&A columns that come up. It appears on the MSDN CD-ROM find it by searching for
Unfortunately, I've tried this a couple times and could not That suggests a technique for causing ON_UPDATE_COMMAND_UI messages to be Paul DiLascia has published a technique in his C++ Q&A column Has allowed me to develop a methodology for handling this. The simple methods illustrated in the introductory textbooks areĬonsiderably less than adequate in this case. Real world, dialog boxes are usually fairly complex, and the enabling conditionsĪre nontrivial. Simple methods are easy to write and easy to maintain. That's because most of them illustrate fairly simple examples, where the Most books that show examples of how to do it get it Unlike windows, there is no ON_UPDATE_COMMAND_UI Have certain controls enabled or disabled, visible or invisible, based on the I don’t know why they are deprecating it.Dialog box control management is a perpetual problem. It is recommended that you do not use it in new programs because it might be altered or unavailable in subsequent versions of Windows. …However, this function is deprecated and not intended for general use. If the specified window is a control, the text of the control is obtained. This is unlike GetWindowText which obtains the text by sending the window a WM_GETTEXT message. However, it obtains the window text directly from the window structure associated with the specified window’s handle and then always provides the text as a unicode string. This function is similar to the GetWindowText function. Microsoft has provided an undocumented API which they say is deprecated, but I find it irresistible… Well GetWindowText has got some problem with it that if you invoke this API on a window that is hung, you application also get’s hung!
