I'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...
Here is the

I'm building a small program and I have a numbers only textbox where its content need to be higher than 1. So what I have is a messagebox pop when the text change and its lower or equal to 0. What I'd like to do is have the text changed to what it was before the number was changed to <= 0.Here's what I have for the control:
Private Sub txtDelay_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtDelay.TextChanged
If txtDelay.Text <= "0" Then
MessageBox.Show("Delay must be atleast 1 millisecond.", "Delay Error")
End If
End Sub

I have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.

If the application is already running, and someone tries to launch it again, set the focus on the already-running program, and exit the one recently launched. I found this, but I don't know how to get the already-running process hwnd. It should be
Dim handle As IntPtr = Process.MainWindowHandle
But that doesn't work.
