In some cases this function will always return the same array, independent of actual keyboard state. This is due to Windows not updating the virtual key array internally. It has been found that declaring and calling GetKeyState on any key before calling GetKeyboardState will solve this issue.

.

         public static int GetKeyState(){

.

            static extern short GetKeyState( VirtualKeyStates nVirtKey );

.

                short result = GetKeyState( testKey );

.
Summary
The GetKeyState function retrieves the status of the specified virtual key. The status specifies whether the key is up, down, or toggled (on, off—alternating each time the key is pressed).
.

static extern short GetKeyState(VirtualKeyStates nVirtKey);

Private Function GetKeyState (ByVal nVirtKey As KeyStates) As Short

    Private Declare Function GetKeyState _

.

        bInserting = GetKeyState(Keys.Insert)

        bInserting = GetKeyState(Keys.Insert)
