Vb.net sendkeys, letters duplicate?

Question

I created a simple test with SendKeys, and tried both SendWait and Send.

 Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
    System.Threading.Thread.Sleep(10000)
    SendKeys.SendWait("If you can read this, it works." + "{ENTER}")
End Sub

I tested in skype, and a few of the letters doubled. I tested in Flash, I got "Iffff yyouu cccaaaannn rrreaaaddd thhhiiisss,,, iiittt wwwooorrrrkkks."

Clearly the issue is caused by lag. What can I do to prevent doubling (or tripling) of letters? I'm probably missing something big here...

Answer 1

In your app settings, try

<appSettings>

<add key="SendKeys" value="SendInput"/>

</appSettings> 

If that doesn't work, try:

<appSettings>

<add key="SendKeys" value="JournalHook"/>

</appSettings>
