GetAsyncKeyState funktioniert nicht.

bankaifan · 22. September 2010

Moin zusammen,

ich versuch jetzt seit nunmehr 1,5 Tagen bei C# "GetAsyncKeyState" nutzen zu können.

Ich hatte in VB.net ein Programm das ich per Hotkey starten konnte. da war es total einfach. Und jetzt brauche ich das bei C#

Bis her sieht es so aus:

	private const int VK_F8 = 77;

	[DllImport("user32.dll")]

	private static extern string GetAsyncKeyState(int vKey);

	void Timer2Tick(object sender, EventArgs e)

                      {

                            	if(!bool.Parse(GetAsyncKeyState(VK_F8)))

	                     {

		                           MessageBox.Show("Test","Test");

	                      }

                      }

Der code beruht fast ausschließlich auf den Ergebnissen von Google. dort gibt es leider zig verschiedene möglichkeite. aber keine funktioniert bei mir. bzw ich schaffs ned.

Danke schonmal.

Nur leider kann ich die eingaben nur abfragen wenn das form ausgewählt ist. hat da noch jmd ne idee?
