Insert Key State

[=?Utf-8?B?Sm9obiBBdXN0aW4=?=]

I want to ensure that the Insert Key state is 'Insert' rather than
'Overwrite' in a particular textbox (or possibly for the whole form). How can
I go about this?

Hi John,

My.Computer.Key board object exposes several properties about keyboard key
status, such as Ctrl key, Caps Lock key, Alt key and Scroll Lock key.
However, it does not contain a property for checking insert key status. So
we have to p/invoke Win32 API for this task. You may use GetKeyState() API
by passing VK_INSERT:

<DllImport("Use r32.dll", CharSet:=CharSe t.Auto, ExactSpelling:= True)_
Friend Shared Function GetKeyState(ByV al KeyCode As Integer) As Short
End Function

Private VK_INSERT As Integer = &H2D

Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
If ((GetKeyState(V K_INSERT) And 1) 0) Then
MessageBox.Show ("Insert key")
Else
MessageBox.Show ("No Insert key")
End If
End Sub

Actually, this API is what My.Computer.Key board object called internally
for its properties. Thanks.

Thank you very much Jeffry, just what I wanted.

Perhaps Microsoft can add InsertState to My.Computer.Key board !

If the InsertStatus is wrong (I want to make sure it is not overwriting),
how do I go about changing it - I can't find a SetKeyState API call?

Thanks,

Hi John,

Yes, I agree with you. You may submit a suggestion to the product team at
the link below:
https://connect.microsoft.com/VisualStudio

Regarding your further question, there is no SetKeyState API. You should
use SendKeys.Send() method to toggle the insert key with parameter
"{INSERT}".

Thanks.

I think I have have been dafter than usual! I placed your code on a form
containing a textbox and button (your code fires when the button is pressed).
Regardless of the state of the Insert key (correctly displayed by your
procedure), the textbox appeared to always be in insert mode!

Hi John,

Yes, this is a by design behavior. The .Net TextBox will not recognize the
INSERT key status to switch between overwrite and insert modes. If you want
to support these 2 modes, you have to code yourself to support them, please
refer to the link below:
"27.11 How can I place a TextBox in overwrite mode instead of insert mode?"

Thanks.
