I need to be able to detect when the background changes, for example user right clicks and selects next background, My first thought was using a FileSystemWatcher on the folder where the images are kept to detect when windows reads a image but that didn't work with the filter to last access but it doesn't seem to be working even when i run as administrator
View 2 RepliesI have Windows XP Pro, SP3 on a Dell Dimension 9150 with VB 3.0 and all other Visual Studios up to and including VS2010 Pro.I'm not exactly an expert VB programmer, but I have written several different programs.I would like to write a VB program to run in the background and detect when the program regedit.exe/regedt32.exe tries to run.Once the regedit program tries to run, I would like my background program to pop up a message with three options. Allow, Do Not Allow and Cancel.
The Allow button would allow regedit to run.The Don't Allow button will not allow regedit to run and continue to run in the background. The Cancel button would not allow regedit to run and would cancel the background program.Can this be done?I would explain why I want to do this, but it would take too much of this thread. However, if anybody really needs to know, I will accommodate their request.

The Textbox_TextChanged event fires when a key is pressed or when text is pasted while cursor is in a text box.
Is there an event that fires on Textbox1.text="NewText"? How do I detect this?My reason for doing this is I would like to reformat text property automatically on assignment rather than do something like textbox.text=myreformat("Newtext").I can put code in validating or validated event but then I'd have to force focus/lostfocus to trigger one of those events.
