RE: How to make StatusBar tooltips? ac2718-Dec-99 4:07 ac271 8-Dec-99 4:07  Have you tried: SendMessage ( hStatusBarWnd, SB_SETTIPTEXT, (WPARAM)(INT)iStatusBarPart, (LPARAM)(LPCTSTR)lpcszTextToDisplayAsTooltip ); code sequence? The status bar window must be created (as in the following example) using g_hStatusBarWnd = CreateWindowEx ( 0L, STATUSCLASSNAME, 0, WS_CHILD | WS_VISIBLE | SBT_TOOLTIPS, 0, 0, 0, 0, hParentWnd, (HMENU)ID_STATUSBAR, g_hInstance, 0 ); For more information, you can check the WindowsNT System Manager, where you can find, among other stuff like this, also something about status bar APIs.

But there are many cases in which strmatch() will fail: strmatch("*?s*", "doesmatch"); doesn't work, because after '*' explicit match to '?' is searched. strmatch("*to*", "doesmatchtoo"); doesn't work because '*t' finds the first 't' and compares "tchtoo" with "to*" - result: no match.

Of course my example will not work correctly in many situations, I've spend about 5 minutes writing it and my main task was to give an idea how you can do this. If you really want to make something like this you should spend much more time coding and testing. You've mention about the recursion but I don't think it's the right place for it, the only place when you can use it is while testing for the '*' but I don't see big advantage comparing to the usual loop. So spend some time, add several IFs and WHILEs and it will work great for you. And don't try to find an existing function, it's always better to do something small like this yourself, because you can always adjust it to your own needs. Don't forget to post the results on the CodeProject and I will also took part in testing...

Thanks RE: Beginer ques on programmng practice Jesse Ezell14-Dec-99 14:56 Jesse Ezell 14-Dec-99 14:56  It would definately take less processor time to pass a reference or a pointer, so this would be the best option in that case. However, you can also have a dialog box class that accepts a Cperson class in its constructor, and then is permenantly linked with that Cperson or a copy of it. It is mostly a matter of opinion and depends on what you intend to use the dialog for. ================== The original message was: Hi I am displaying information of a simple Cperson class in a dailog box - which is better practice to pass the information by parameter to the dailog via DDX or to pass a pointer to the Cperson object and let the dailog box extract the data ? Thanks Re: Beginer ques on programmng practice Tomb28-Jun-00 11:10 Tomb 28-Jun-00 11:10  My suggestion would be pass a reference to the object and let the Dialog interrogate the object directly for the data. Why pass n parameters when half the raison d'etre for the object is the encapsulation of this data? Pass a reference. In fact, there are probably ways to display the data in a dialog in such a way (combined with a bright method or two in the CPerson object) such that you can change the internal data represented in the CPerson without having to modify the Dialog that displays it. One of the stratagems of the experienced programmer is to try to devise ways to insulate himself from changes in data structure within object classes - this tends to happen, and the less impact it has on code scattered across the project, the better.
