Single instance mode issues #288

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I've noticed 2 issues when enabling single instance:
- the 2nd instance crashes instead of diying
- the app freezes when pressing "exit key" (manually quitting the app is ok)

I did not see my Single Instance crash.  EmuHawk was told it's single instance 
and then reloaded in Single Instance mode.  Loading EmuHawk if the old instance 
is not told to be single instance and the mode is set.

I've made a test launching the 2nd instance from Visual Studio in debug mode.
Here is where it stops:

Pressing a custom "Exit key" when single instance mode is enabled does not get 
you a crash: the emulation stops but the windows stays on until you manually 
close it.

Confirmed on SVN Build r8178

Reproduction Steps:
Enable Single Instance Mode and close EmuHawk fully.
Reopen EmuHawk.
Attempt to open another Instance of EmuHawk.
Error message and First instance freezes until the error message is cleared.

I get this error:
************** Exception Text **************
System.ArgumentOutOfRangeException: Index was out of range. Must be 
non-negative and less than the size of the collection.
Parameter name: index
   at System.ThrowHelper.ThrowArgumentOutOfRangeException()
   at System.SZArrayHelper.get_Item[T](Int32 index)
   at BizHawk.Client.EmuHawk.Program.SingleInstanceController.this_StartupNextInstance(Object sender, StartupNextInstanceEventArgs e)
   at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.OnStartupNextInstance(StartupNextInstanceEventArgs eventArgs)
   at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.OnStartupNextInstanceMarshallingAdaptor(Object args)

Close Emulator hotkey appears to be working fine for me in single instance mode.
