Exact Code Produces Different Results

[Raeki]

So, I have this code.

Case Keys.U
                    With Me.TextBox1
                        Dim selectionStart As Integer = .SelectionStart
                        Dim selectionLength As Integer = .SelectionLength
 
                        .SelectedText = underline & .SelectedText & underlineend
                        .SelectionStart = selectionStart + underline.Length
                        .SelectionLength = selectionLength
                    End With
                Case Keys.I
                    With Me.TextBox1
                        Dim selectionStart As Integer = .SelectionStart
                        Dim selectionLength As Integer = .SelectionLength
 
                        .SelectedText = underline & .SelectedText & underlineend
                        .SelectionStart = selectionStart + underline.Length
                        .SelectionLength = selectionLength
                    End With

It is inside if e.modifiers = keys.shift and a select case e.keycode

The code inside case keys.u is the exact same as keys.i, yet whenever I press control-i, it adds a whole bunch of spaces between the "underline" and "underlinelength" strings. So control-u produces

[u][/u]

but control-i, with the exact same code, produces

[u]                  [/u]

It's getting really frustrating... can someone please shed some light on this ridiculous malfunctioning?

Urgh, and what I find EVEN MORE annoying is that if I replace e.keycode = keys.i with e.keycode = keys.p, there is no problem!

Have you put a breakpoint in those two cases to see what the selection length is? What I am wondering is whether the issue is within that code, or in the selectedtext. Of course, it would probably look the same, so I guess the actual comparison would be on the selectedText.Length property.

I found that control-i seems to put that big block of spaces in... its one big character

Any way to cancel that? The auto-recognition like control-z is autmatic without me coding anything

Do you have any hotkeys defined on that computer? A big chunk of space like that sounds like a tab, or some similar thing. If you identify that, you might figure out why it is being added. Offhand, I don't know of anything. Of course, if it always happens, and the length is one higher than it should be, you might just remove that one character whenever you press that key combination.
