Is it possible to remove the checkboxes from a .NET WinForms ListView control at runtime? The following code appears to have no effect when '.Checkboxes' has initially been set to 'true' and the control has rendered onto a form with checkboxes available for each list view item: // C#: testListView.BeginUpdate(); testListView.Checkbox...
My goal is to have this program send a logout command when the user is logging off or shutting down their pc. The program is connected to a server application via a tcp socket using a Winsock object. Calling singleSock.SendData "quit" & vbCrLf is simply a way of logging out. I am going to start capturing data with Wireshark, but I'd l...
I'm writing a Toast that needs to be thread-safe as it's being used to report the status of asynchronous socket input. I've tried to make it thread-safe but the toasts are still locking up. public static void Show( string message ) { Toast toast = new Toast( message ); toast.ShowAction(); } private delegate ...

I was recently adding some drag/drop functionality to a usercontrol that I'm creating, and I decided that it made sense to factor the specifics of drag/drop out for subsequent testing, etc. The core logic is in DragOnMouseMove<TInput>(). (Formatting trimmed for brevity) internal class DragState { private static readonly Size deadZ...

We have a WinForms app that runs fine on x86, but has many third-party components that make win32 calls. To get the apps to run on x64, I now compile for the x86 platform. Our habit has been to install our thick-client outside the system partition on servers, so we installed in "F:\Program Files (x86)" yesterday on a Win2003 x64 server. ...

I'm currently thinking of a new pet project, an "editor" for MIDI-enabled synths. I've got the MIDI side covered, I suppose, but what I'm looking for right now is something that can pass for nice "dials" and "knobs" like you see in Ableton Live, Reason, Reaktor, and so forth. Putting my form full of trackbars, is sort of wasteful, y'kno...

Hello, does anyone know how easy it is or how possible it is to skin a .net Windows Forms DataGridView control? I'd like to render the control vastly different then what it currently looks like.
