Hallo zusammen!

Ich habe ein großes Problem. Ich versuche schon über einen längeren Zeitraum einme externen Programm was zu schicken. NEIN nicht über senkkeys sonder über eine API Schnittstelle.
Achso ich mach das Ganze in VB.NET VS2008 eine Konsolen Anwendung.
So weit so gut. Das funktioniert auch bis zu einem gewissen grad, aber jetzt kommt mein Problem. Ich habe versucht einen Unterstrich zu Versenden, den ich Brauch, damit ich was anderes Starten kann.
Anbei mein Code:

Wie ihr in der dritt letzen Zeile seht, versende ich einen Unterstrich. Aber den wird einfach ignoriert. Bitte helft mir. Achso der Code ist so lauffähig in einer Consolen Anwendung unter VS2008

Hi,


einmal brauchst du das hier ...

//Sind zwar gleich aber zum entscheiden ob shift gedrückt werden soll hilfreich
VK_UNDERSCORE = 189
VK_Minus = 189

ElseIf sChar = "_" Then
VK = eVirtualKeyCode.VK_UNDERSCORE
ElseIf sChar = "-" Then
VK = eVirtualKeyCode.VK_Minus

ElseIf sChar = "+" Then
......


und dann noch vor dem Drücken bei Underscore Shift drücken:

If VK = eVirtualKeyCode.VK_UNDERSCORE Then
keybd_event(&H10, 1, 0, 0) //Shift
End If

keybd_event(VK, 1, 0, 0)
keybd_event(VK, 1, KEYEVENTF_KEYUP, 0)

das wars
jetzt gehen auch '-' und '_'


P.S.
Falls noch Zeichen fehlen einfach das hier in die main ..

While (True)
Dim a As System.ConsoleKeyInfo
a = Console.ReadKey()
End While

und wenn du dir a dann anschaust siehst du den Code in dez.
sonst auskommentieren.
