Capture Shift Held Down When Application Starts?

[Alex Stevens]

Hi All,

I'm writing a launcher program which checks for updates and copies them down
to the client.
However, I would like the user to be able to modify the settings for the
launcher. As this runs automatically, I would like it to be configurable by
the user holding down the shift key when double-clicking my exe, to bypass
the usual update routine and start the config form.

Access does something similar, by holding down the shift to bypass the
autoexec macros with automatically starts on startup.

I'm already checking for command parameters to start the config, but that
isn't acceptable, and the user would have to modify the shortcut etc.

Any ideas?

Thanks

Alex

Alex,
Have you looked at using System.Windows.Forms.Control.ModifierKeys to see if
one of the modifier keys (SHIFT, CTRL, & ALT) is in a pressed state or not?

Hope this helps

Othman,

It seems that there is something wrong because your replies don't contain
any text...

 

[Samuel R. Neff]

If Control.ModifierKeys = Keys.Shift Then
' Shift is being held down.. special processing...
End If

This checks if Shift is the only modifier key being pressed. If you
want to check if shift or any other key is pressed, then use

If (Control.ModifierKeys And Keys.Shift) = Keys.Shift Then
' Shift is being held down.. special processing...
End If

HTH,

Sam
