[RESOLVED] Clearing part of a console

[i00]

How can I clear part of a consoles output??

E.g if I have this:

Console.WriteLine("The quick brown fox jumped over the lazy dog" & vbCrLf & "The quick brown fox jumped over the lazy dog")
Console.CursorTop = 0
Dim ClearText = "a" & vbCrLf & "b"
Console.WriteLine(ClearText)

The a and b will only replace the first 2 letters of each line; not clear the lines...

I considered replacing them with spaces, but when this happens, after making the window narrower, it pushes the b in:

Console.WriteLine("The quick brown fox jumped over the lazy dog" & vbCrLf & "The quick brown fox jumped over the lazy dog")
Console.CursorTop = 0
Dim ClearText = "a" & New String(" "c, Console.BufferWidth - 1) & "b" & New String(" "c, Console.BufferWidth - 1)
Console.WriteLine(ClearText)

Is there anyway just to clear part of the console?

Thanks

Ok ... worked it out .. need to use:
Fill this way with Chr(32) via API:

FillConsoleOutputCharacter(OutputHandle, Chr(32), 1, cord, CellsWritten)
