Hi,

I have some problems with the Keyboard Module in the KeyDown event in an Editfield.

This code works properly...

  if Keyboard.OSKey = true then
    if key = Lowercase("r") then
      DoPreviewDocument()
      Return true
    end if
  end if

---------------------------------------------------------

This code is not working, the Keyboard.ControlKey is fired properly, but the 'Key' (from the KeyDown event) is blank.

Checked in the Debugger ( size 1 ASCII / but blank )

In the Keyboard.OsKey the 'Key' variable is shown properly in the Debugger.

  if Keyboard.ControlKey = true then
    if key = Lowercase("a") then
      JumpTwice()
      Return true
    end if
  end if

Any ideas about this?

Using the control key is supposed to produce non printable characters (or beeps on some applications which prevent that). Control-a won't produce the "a" character (it's like when you type "option-p": you get a special character (here: "π"), but you only know that final character, not the "p" key)).

Here's how I do it (it was the only way on RB 5.5, but I don't think something has changed; I'm still on RB 5.5):

Function IsKeyDown(key As String) As Boolean
  dim i As integer

  for i=0 to 127
    if Keyboard.AsyncKeyDown(i) then
      if Keyboard.KeyName(i)=key then Return True
    end if
  Next
End Function

This won't works for special keys (delete, for example) since the produced characters won't be "delete", obviously ;-)

Hope this helps._______________________________________________

Hi,
Thanks for your response...
The problem was more like 'out of memory' or 'memory overflow'

Thx,
Sven E
