So you're saving an image as XML? This is why we need 1TB+ harddisks these days.

You need to send a WM_HSCROLL[^] or WM_VSCROLL[^] message. You can use SendMessage()[^] or PostMessag()[^] to send the message to the control. Simon

Seraph_summer is correct - for some reason MS have hidden it from the designer but it's available in the editor. I'll check the source later and see if I can figure out why! listView1.MouseWheel += new MouseEventHandler(listView1_MouseWheel); void listView1_MouseWheel(object sender, MouseEventArgs e) { // Do stuff! } Dave BTW, in software, hope and pray is not a viable strategy. (Luc Pattyn) Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

I don't know about any easy way how to achieve that. Personally I would prefer to find a non-software solution, but if you insist ;-) I would: 1. limit the account the kids are running under (if not done already). If they are admins, you can do nothing they are not able to overcome. 2. Write a service that is optionally attached to the WTSRegisterSessionNotification (WinXP+). This helps you to use their windows logon to measure the time they spend on the computer in total. Also can help to detect who is trying to overcome the security mechanism. 3. Set the service as autorestarted for any case (service settings). 4. Disable the network connectivity on the service startup (e.g. disable the ethernet card). 5. Write the communication application that is on one side communicating with the service, on other side asks for the specific username/password allowing to start the internet session. 6. The application will pass the credentials to the service. 7. Service will enable the ethernet card for use for valid credentials. 8. Logoff from the windows or from the communication application will cause the eth card to be disabled. 9. In cause the service is killed somehow, windows will restart it. Because of 4. the internet connection is disabled. This all will pops-up some questions: 1. what is a Internet spending time - I can download a bunch of pages at all in a few seconds, then read it for a week (offline browsing)? On the other side I can download e.g. a large iso image of my school project from slow school server physically not being at the computer - meanwhile helping at home with some other tasks ;P. 2. How to manage the software solution that someone will not simply bring in a notebook, disconnect the original computer and browse from that notebook? 3. above solution is quite difficult to manage with user-switching (although not impossible, but can be overcomed by another software running on background in suspended account waiting for the connection to be enabled from another account) Another possibilities (solves 2): - custom proxy - measure the time on other computer used as an authenticated proxy server. Set your network that the internet is not accessible in any other way without using this proxy. Lock proxy in secure place.

You're welcome. Glad my advice was useful. Best, Jun

hey guys Can we do the same through vb.net if yes tell me also abhinav

Never mind - I figured it out. It is passed as "Index" in the event args object! dpb Darryl Borden Principal IT Analyst dborden@eprod.com

Google[^] has. I'm sure one of those will help you. Christian Graus - Microsoft MVP - C++

You can remove them tabControls.TabPages.Clear(); and then re-add them in whatever order you want tabControls.TabPages.Add(tabPageOne);

This commonly happens when a multi-threaded app has different threads setting properties on the controls that were created in a different thread, or when unhandled exceptions occur during instantiation of the main application form (the form used in the call to Application.Run). First go through and make sure that you're handling all exceptions that could occur during instantiation of your child controls and that no worker threads are setting properties (and many times even getting properties) or calling methods on the controls from those threads (see Control.InvokeRequired and Control.Invoke in the .NET Framework SDK for more information). A work-around is to use Application.Quit for your File->Exit (or whatever) menu instead of just calling Close on your form. Microsoft MVP, Visual C# My Articles

Yup - I've experienced it. It was an OpenGL control with mouse interaction, and didn't bother to work out WHY it happened - I just stopped it being a pain with following pseudocode: PointOrWhatever savedPosition; void HandleMouseEvent(whatever args) { if(args.position == savedPosition) return; DoMyMouseMovingStuff(); savedPosition = args.position; } Regards Brewman

Cursor.Position = somePoint; If you want to limit that point to be on the control, use the control's .PointToClient method. For example, Point somePoint = new Point(0,0); Cursor.Position = myControl.PointToClient(somePoint); The graveyards are filled with indispensible men.

This is happening because, while the control is not visible, the Windows handle is not created. When the Windows handle is not created, no sorting (and a few other things) is done. If the control is visible - even if it isn't currently painting items - it sorts with each addition to the Items collection! Even using the LockWindowsUpdate API won't do anything to resolve this issue. The BeginUpdate and EndUpdate methods essentially do the same thing. They disable and enable drawing (respectively) by using the WM_SETREDRAW message. While it isn't documented, LockWindowsUpdate probably does this very same thing. So, you'll either have to bite the bullet and accept the lag, or hide your control and reshow it when you're finished, but that might be annoying to the user. If nothing else, show a progress bar (so add the items in a separate thread, but be sure to use InvokeRequired and Invoke to actually add the items!) while you're adding items to the user knows that something's happening and that they should way. You should also use a try-finally block to show the wait cursor (Cursor.Current = Cursors.WaitCursor) and, in the finally block, set it back to the default (Cursor.Current = Cursors.Default). -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

I have figured it out - I can create a servicecontroller component and issue a stop from there. Darryl Borden Principal IT Analyst darryl.borden@elpaso.com

Never mind on the 2nd question. If I insert a "\n" character in the string then it wraps to the next line in Excel! "1,2,3,4,5\n6,7,8,9" Thanks again for your help. dpb Darryl Borden Principal IT Analyst darryl.borden@elpaso.com
