Re: to lock an application Diddy15-Jan-04 5:37 Diddy 15-Jan-04 5:37  You can use GetLastInputInfo on Win2k to give you the time of the last "input" event - and compare that to the current time and then lock the app if the time out has gone If you wanna run on 9x I think your into hook land - look up WH_FOREGROUNDIDLE - you might find this http://www.microsoft.com/msj/0200/c/c0200.aspx and this http://msdn.microsoft.com/msdnmag/issues/0500/c/default.aspx useful which do what you want.

Then set this value to whatever idle time you are interested in. Once that idle time has been reached, Windows will broadcast a SC_SCREENSAVE message. When your application ends, restore the screen saver timeout value to what it was. Another idea that comes to mind would be to call SetWindowsHookEx(). As far as which type of hook to use, I don't know. Several of them look like they might work, but ultimately it'd probably be only one of them. Classier ways may exist, but having never done this, I'm not familiar with them. A rich person is not the one who has the most, but the one that needs the least. Re: to lock an application Idefix22-Jan-04 0:37 Idefix 22-Jan-04 0:37  Many thanks for your suggestions. I realized the application lock to filter out the messages WM_KEYDOWN, WM_SETCURSOR, WM_MOUSEMOVE ... I use the WindowProc from CMainframe and PreTranslateMessage from the Application to keep the user event in mind. I set a timer to pull the last user event and divided the time of timer by 10. When the timer the peeks the noted user event it puts them back. After 10 times without user events the applcations will be locked. It goes well and is not so complicate. I get another problem with messageboxes. When a messagebox appears there are no window messages In addition I have to handle a opened messagebox. At the moment I'm thinking about this problem. Thanks Re: to lock an application Idefix22-Jan-04 1:47 Idefix 22-Jan-04 1:47  I'm so stupid. Why I haven't tried GetLastInputInfo at first? (don't answer me) That works very simple and it is what I wanted. Thanks Capture LButtonUp in a CListBox ?? jwd15-Jan-04 0:38 jwd 15-Jan-04 0:38  Hi, I have at CListBox in a dialog box but I'm not able to capture mouse click (ex. LButtonUp() ) ? Context-menu works fine on the mouse right click. Can anybody help me ? Re: Capture LButtonUp in a CListBox ?? Vladimir Georgiev15-Jan-04 0:51 Vladimir Georgiev 15-Jan-04 0:51  If the List box does not provide a way handle a message - WM_LBUTTONUP message in your case, you will have to use subclassing (write your own message procedure) for this control. See the articles on subclassing here at CP, or at msdn.microsoft.com... "Needless redundancy is the hobgoblin of software engineering." - Peter Darnell Re: Capture LButtonUp in a CListBox ?? Diddy15-Jan-04 5:54 Diddy 15-Jan-04 5:54  Have MFC subclass it for you with a DDX_Control statment, if its based on a resource: 1. Derive a class from CListBox 2. Double click on the list box in the resource editor with CTRL held down 3. Select control 4. Select your new derived list box class 5. Give it a name Then use class wizard to add a handler to your LB for WM_LBUTTONUP to your new LB the problem of mscomm32.ocx and vc++ anders_zhou15-Jan-04 0:26 anders_zhou 15-Jan-04 0:26  hi!

Re: Resolving NetBIOS name for IP address ---Ranger---15-Jan-04 17:45 ---Ranger--- 15-Jan-04 17:45  1. gehostbyaddr() too slowly for LAN (resolving timeout is too big) 2. Name rsolved by gethostaddr can be both DNS or NetBIOS.

Large Text Display in a Dialog Dov Sherman14-Jan-04 22:56 Dov Sherman 14-Jan-04 22:56  I need to display a long block of scrollable text in a dialog. I tried using a read-only CEdit but it doesn't seem to allow more than ~65000 characters. Is there a way to increase the amount of text a CEdit can display? Or is there a different, more appropriate solution? Re: Large Text Display in a Dialog jhwurmbach14-Jan-04 23:11 jhwurmbach 14-Jan-04 23:11  A CRichEdit can handle almost any amount of text. Just remember to call AfxInitRichEdit before trying to display the dialog. Who is 'General Failure'? And why is he reading my harddisk?!? Loading Bitmap Image sweep12314-Jan-04 22:45 sweep123 14-Jan-04 22:45  I am trying to place a high resolution bitmap on a Picture control. I resize the image to fit on the picture control. However I lose some resolution (its quite bad). I did try and load the image as a jpg and gif and wmf but keep getting the error: c:\Task_Emu\Task_Emu.rc(339): error RC2170 : bitmap file res\PrimaryFlight.gif is not in 3.00 format I have looked at the properties of the Picture control and Bitmap (set to True colour). Are they antthing I can do to get the bitmap (or jpg) displayed a bit better. I expect some lose of resolution, but just want it a bit better if possible Regards, Sweep123. Re: Loading Bitmap Image LunaticFringe15-Jan-04 6:14 LunaticFringe 15-Jan-04 6:14  How much are you resizing it? Re: Loading Bitmap Image sweep12315-Jan-04 6:22 sweep123 15-Jan-04 6:22  Quite a bit! The original image was done in CoralDraw and converted to bmp format (size ~2.MB). Other programs, Paint, PaintShopPro display the detail, its just the Picture control seems to break it up a bit. All I want was a bit more detail if possible. Does that help? Re: Loading Bitmap Image LunaticFringe15-Jan-04 11:01 LunaticFringe 15-Jan-04 11:01  I'm not sure this will help, but you could try StretchBlt'ing the image to a DIBSection in RAM and displaying that. Network connection problem Stan the man14-Jan-04 22:43 Stan the man 14-Jan-04 22:43  Hi. My question is how does a server knows if the connection is suddenly gone for example if the hardware connection is broken? Usually a server will send alive messages etc to the client so the client will know. But how does a server know if that side is gone when it is not shutdown "gracefully?" Is there a function call to help with this? Thanks in advance.
