setPopup not working + minimize window question

[bgowland]

Firstly - the setPopup call isn't working in this piece of code. Everything else is fine and I see the Logger messages for 'About to set popup' then the one for creating the process....but no popup appears.

Code:

Logger.Verbose("Play invoked");
if (DVBTRadioProc == null)
{
    Logger.Verbose("About to set popup");
    setPopup(new GBPVRX2.Popups.PopupMessageBox(this, "Starting DVB-T Radio service. Please wait..."));
    try
    {
        Logger.Verbose("About to create process for Dvbtr.exe");
        DVBTRadioProc = System.Diagnostics.Process.Start(GBInstallDir + @"plugins\DVB-T Radio\Dvbtr.exe", "529834 8 9018 16384 18560");
    }
    catch (Exception e)
    {
        Logger.Verbose(e.ToString());
    }
    finally
    {
        setPopup(null);
    }
}

Second question - Dvbtr.exe is a command-line program so I get a command prompt appear on screen. How do I start this minimized? I can see the Process.MainWindowHandle property but that is an IntPtr and I can't decide how to use it. Or is there another way?

Cheers,

Are you sure that setPopup(null) isn't being fired before the popup is displayed?

As or the minimized window, you need to set the start parameters on the process. I have some exaple code somewhere. I'll try to find it.

1) GBPVR does not have a chance to render your popup. You create it and destroy it in the same thread, same unit of work.

You should create the popup, then spawn a thread to Dvbtr work. When that (Dvbtr work) thread ends, you can set popup to null.

2) Take a look a ProcessStartInfo. You should be able to use ProcessStartInfo.CreateNoWindow to hide the window. If you only want to minimize, try ProcessStartInfo.WindowStyle = ProcessWindowStyle.Minimized.

Thanks guys.

I thought about it a bit more after I posted and it is probably the case that the popup just doesn't get the chance to appear. The Process.Start method is returning almost instantaneously. I'll probably just take the code out as it isn't really neccessary to have a 'Please wait..." message for an instant action.

I'd briefly looked at ProcessStartInfo but hadn't spotted the window control stuff. I'll give it a try.

Sorry, I somehow missed this thread otherwise I would have replied. The guys have set you on the right path with their replies above.

ProcessStartInfo was the start parameters I was refering to but I was too lazy to fire up VS and check. Sorry.
