Invoke or BeginInvoke cannot be called...Solved

Hi

I'm getting the following exception from AutomaticUpdater control when my application starts (with the latest Version):

Stacktrace bei System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) bei System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) bei System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) bei System.Delegate.DynamicInvokeImpl(Object[] args) bei System.Windows.Forms.Control.InvokeMarshaledCallbackDo(ThreadMethodEntry tme) bei System.Windows.Forms.Control.InvokeMarshaledCallbackHelper(Object obj) bei System.Threading.ExecutionContext.runTryCode(Object userData) bei System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) bei System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) bei System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) bei System.Windows.Forms.Control.InvokeMarshaledCallback(ThreadMethodEntry tme) bei System.Windows.Forms.Control.InvokeMarshaledCallbacks() bei System.Windows.Forms.Control.WndProc(Message& m) bei System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) bei System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) bei System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) bei System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) bei System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) bei System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) bei System.Windows.Forms.Application.Run(Form mainForm) bei ch.hbs.moto.cl.Program.Main() in C:\Projects\HBS_KMU\Kmu\Client\src\Program.cs:Zeile 69.Inner Exception

Looks like AutomaticUpdater calls Invoke on the owner form before the form's handle is created. You should wait until ownerForm.IsHandleCreated returns true before doing anything with the ownerForm.

Can you fix this?
