Re: CMyListCtrl - Limit subitem charactercount Roger Allen24-Mar-03 1:25 Roger Allen 24-Mar-03 1:25  If you popuping up an edit control to allow th edit, you can just call LimitText (EN_LIMITTEXT) function to set the maximum number of characters which can be entered by the user for the columns you need to limit.

I've seen that in Star Trek Armada and Star Trek Elite Force, and I wondered how that could be done. I've tried a keyboard hook, but I can still Alt+Tab out of my application, open the Task Manager or display the Start-Menu. Thanks, widi - Re: keyboard hook Rickard Andersson2023-Mar-03 23:18 Rickard Andersson20 23-Mar-03 23:18  Did you post three messages by misstake or are you trying to be bothersome? Lookup SystemParametersInfo() in MSDN and look for a flag named SPI_SETSCREENSAVERACTIVE. It only works for Win 9x! Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN!

Re: keyboard hook Joerg Wiedenmann23-Mar-03 23:27 Joerg Wiedenmann 23-Mar-03 23:27  Thanks. - Re: keyboard hook Joan M23-Mar-03 23:58 Joan M 23-Mar-03 23:58  If you want to hook the keyboard, you should create a system wide keyboard hook, this kind of hook must be placed in a DLL, and can be installed from anywhere (your program, a service...). In order to hook any key this should be right, but if you want also to control Ctrl+Alt+Del you should create a gina.dll that would allow you to handle it, if you don't want to do this and you don't mind a messagebox (horrible by my point of view) you can search for a question like yours 5 or 6 days before that asked more or less the same, the fact is that somebody told there that it was a method to handle the Ctrl+alt+del... there without a gina.dll. the best way to do it is the gina.dll... Re: keyboard hook Anonymous24-Mar-03 20:43 Anonymous 24-Mar-03 20:43  Thanks, I've installed that low level keyboard hook and it works . I don't know what you mean with that gina.dll , but I now searching that question (this could take a while because of the high-tech internet connection in my school (2,2 kb/s)). Thanks again -widi P.S. Today, computers in school are working great again ... I've signed in and what do I see in the Your Name Edit ? Anonymous ?? - s**t f*****g school-computer. Sorry , but this time I had to say someting... Re: keyboard hook Joan M24-Mar-03 21:31 Joan M 24-Mar-03 21:31  The gina.dll is a special dll that controls the autentification of users and Ctrl Alt Del (and other stuff also). It's a security matter: Microsoft couldn't allow anybody to write down a simple program that could capture the paswwords or info related to one user in the logon screen. And in order to avoid that they use a GINA.DLL that has all related to the logon (including the CtrlAltDel). the only way to make it work properly is to make a GINA DLL (or to get someone that is already made) and substitute the one in the system. This means that in order to do so you must have permission of the administrator of that computer to do that... hope this helps...
