Disable keys

Hi,

i currently have a program, it will run full screen so it cannot be closed without the use of a button, i want something that will disable ALL keys apart from the few keys i want to be enabled, is there a way to do this and if so how?

as an example if possible lets say the letters A,B,C, will be all unblocked.

thanks

you could make a list of all keys, and use "for each" to filter A, B and C out.
and just search the forum for the code to disable the keys.

In the Form_KeyPress event, put code similar to the following:

VB Code:

If KeyAscii = 97 Then
        'A Key was pressed, so do something
    ElseIf KeyAscii = 98 Then
        'B Key was pressed, do something else
    ElseIf KeyAscii = 99 Then
        'C Key was pressed, do yet another thing
    Else
        KeyAscii = 0
    End If

Thanks mark thats very useful :D

To make MarkDorf's code more readable use VB's built in constants

VB Code:

If KeyAscii = vbKeyA Then
    'A Key was pressed, so do something
ElseIf KeyAscii = vbKeyB Then
    'B Key was pressed, do something else
ElseIf KeyAscii =  vbKeyC Then
    'C Key was pressed, do yet another thing
Else
    KeyAscii = 0
End If

In case you need the Full ASCII table

thanks :D (yeah i already had an ascii table but this one it much easier thanks)
