I have a problem with MouseEvents on my WinForm C# application. I want to get ALL mouse clicks on my application, but I don't want to put a listener in every child component neither use Windows mouse hook.

I am using a background thread to initialize an instrument over USB. The UI hangs when I try to open the device. I would expect the background thread to pause when calling Open on the device, but not the UI thread. I am testing this with no UI interaction from the background thread. I don't know how to debug the problem, and it's too bro...

I have a WinForm TreeView Control that displays the Parent Child relationship of CaseNotes(I know that means nothing to most of you but it helps me visualize the answers). I have a DataTable of the CaseNotes that I need to display. The Parent/Child is defined as: If the row has a ParentNoteID then it is a childNode of that note other...
Hi all, I've searched the web and I can't seem to find anything that will work for me. I've seen plenty of discussion, and even some fairly extensible open-source tools, for code editors that provide line numbers and syntax highlighting. Here's my dilemma...

I've got a "Main Window" containing quite a few things, including, in the status bar (at the very bottom of the window), a "Support" button, which the user can use at any time to open a window containing our support phone number, along with a little chat functionality if the user prefers to chat with us. The problem is that if the progr...
I've got a DataGridView in a modal window with a list of options for my program. The grid has two collumns. The first one contains a checkbox for selecting that option, the seccond is the name/description of that option. The winform also contains OK and cancel buttons but that's beside the point. The code below does what I want it to. Be...

I have a Winforms project with a single .exe file as the primary output. I'm using a deployment project to distribute it, but the .exe file is not being updated when the new version is installed, meaning I have to ask the users to manually uninstall and then install the new version. Here's what I'm doing: I increment the assembly vers...
