Cannot Undo SystemParametersInfo API Call ! Please Help !!

Hi
I wanted accelerator keys to show for my users, so I followed the instructions in http://www.codeproject.com/KB/dotnet/General.aspx
However I cannot work out how to call the function to reverse my change !
Thanks
Nick

Public Class AcceleratorKeyVisibilityUtils
    <DllImport("user32.dll")> _
    Private Shared Sub SystemParametersInfo(ByVal uiAction As UInteger, ByVal uiParam As UInteger, ByRef pvParam As Integer, ByVal fWinIni As UInteger)
    End Sub
 
    Const SPI_SETKEYBOARDCUES As UInteger = &H100B
 
    Public Shared Sub AcceleratorsVisible_ChangeSystemSetting(ByVal pShowAccelerators As Boolean)
        SystemParametersInfo(SPI_SETKEYBOARDCUES, 0, pShowAccelerators, 0)
    End Sub
 
End Class

Hello orekin,

Maybe you can use SPI_GETKEYBOARDCUES (0x100A) action to get current settings?

I'm not sure what you mean.
Wouldn't SPI_GETKEYBOARDCUES be used to retrieve the settings ?
I want to change the settings back to what they were - in other words "Hide Underlined letters for keyboard navigation until I press the ALT Key"

Sorry, I misunderstood.

Try to set pShowAccelerators to False

Well, yes, I tried to set pShowAccelerators = False and it does not reverse the change.

Anyone else have any ideas ? This should be a solvable problem ....

Another unanswered question of mine.
Another question that a moderator will forcibly close.
Yet this question is direct, short and clearly expained.
It seems that Experts Exchange is a Waste of Money
