Answer 1

To modify the system’s cursor, we need to change items in the following registry:

HKEY_CURRENT_USER\Control Panel\Cursors\

 

After that, we call the Windows API SystemParametersInfo with SPI_SETCURSORS to force the system cursors reloaded.

 

VB.NET codes:

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

#Region "SystemParametersInfo"

    Declare Function SystemParametersInfo Lib "User32" Alias "SystemParametersInfoA" ( _

        ByVal uAction As Integer, _

        ByVal uparam As Integer, _

        ByVal lpvParam As IntPtr, _

        ByVal fuWinIni As Integer) As Integer

 

    Private Const SPI_SETCURSORS = &H57

    Private Const NULL_PTR = 0

#End Region

 

    Private Sub ButtonSend_Click( ... ) Handles ButtonSend.Click

        SystemParametersInfo(SPI_SETCURSORS, 0, NULL_PTR, 0)

End Sub

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