• swells Writing exe path to registry.

  How would I write the path of the current program I am running to the registry using either the load event or in a setup program Thank You! I'm sorry, I worded that wrong. How could I get a setup program, when run, to write the path of the install directory to the regristry using the setup & deployment project installer, you would have to create a custom action to do this, again using the same method above. You would probably create this custom action on the AfterInstall (or something similar to that, or on the Commit event) event. http://msdn.microsoft.com/library/default.asp url=/library/en-us/vsintro7/html/vbconCustomActions.asp http://msdn.micr ...Show All

• P.H. Monitoring Changes on a Tab Page

  In my WinForms app I have a tab page with a bunch of controls on it (e.g. textboxes, checkboxes, buttons, radio buttons, etc.). Is there an event, or a few events, of the tab page that I can monitor to see if any changes to any controls on the tab page have been made Robert W. http://pocketpollster.com rwerner wrote: It is not the selecting of the tabs I'm interested in but the altering of controls on a tab page. I thought perhaps there was a "Parent Control" event that would be fired when anything happened to any control on a tab page. Apparently not. As you're seen, there's nothing "built-in" like that. As nobugz mentioned, you could iterate all the contained controls and ...Show All

• brohans Uninstall removes files and leaves executable running

  Hi, I have used VS2005 to create a .msi package for my software. The problem though is that when I uninstall the software either through "Add/Remove Programs" or through running the uninstaller again, the uninstaller will remove all of the files but leave the executable running. Is there anyway to have the Installation project stop the executable, both when the application is in window form and in the system tray Thanks, Adam I'm thinking about doing the same, but the .exe doesn't seem to be deleted on uninstall (Probably because it's running ) I found the fix on another forum... I created a FileWatcher to watch when the .exe was getting deleted. When it did ...Show All

• NuclearChicken Incremental Search

  Hi, how can i do a incremental search in a DataTable or DataGridView I was a Delphi developer and now i'm studing and developing .NET/C#.

Thanks, Rob I have been trying to figure this out for a while now and ran into the same problem with IComparer.

• sGurpreet OpenGL control

  Hello everyone ! I'm new to windows forms ( actually I started kinda...today)...  I was able to bind an OpenGL context to a form, and later create a GLForm derived from Form. Both worked perfectly, no flickering at all, but I was rendering directly in the form. I'm now trying to create a OpenGL control, derived from UserControl, which alows me to render only in that control. I was able to create the control and render onto it, but  it's flickering... alot, I tried to override the OnPaintBackground method of both the control and the form that holds the control, but flickering was still there .... My paint method is very simple, it just clears the screen using OpenGL, render stuff, and then  swap buffers. Anyone had a pr ...Show All

• Mike Greenway Threading and the FileSystemWatcher

  I need some help with the filewatcher class. I am trying to use it to monitor a directory and get the list of files that are created and deleted from the directory.
