When they click the Restore button I want it to show a different, smaller, minified, form, which will show them a maximize button which will return the use to t...
I'm looking at this control, and it seems to be lacking the standard .net "datasource" and "datamember" properties for databinding. Is this control not bindable? I can write some custom function that populates the treeview from a given data source, I suppose, and embed data objects as necessary, but is that the 'best practice'? Or doe...

Might sound like its tr...

The application I'm trying to localize is a WinForms application that has a few hosted WPF user controls (WPF user controls hosted in an ElementHost WinForms control). I use resx files to localize the WinForms, which VS2008 manages quite well. The problem starts when I try to use the LocBaml method to localize the WPF parts. Here's wh...
I'm trying to write a chat client in C# and have run into a problem. How it works is that the client polls the server every 1 second to see if there are any new actions to take (for example display a message in a channel, or whatever). The polling is done in a thread of its own. Now, I want the polling thread to open a new MDI form whe...

I'm using .Net 2.0 and this is driving me crazy but there's probably some easy thing I'm not doing that I am now too confused to see. I have an application that has a bespoke collection of objects in it, only the main form should be able to change the contents of that collection and all other forms should be able to read from it. Actu...
Hello, I have a custom control that uses a designer I've inherited from ParentControlDesigner to allow child controls to be dropped. I'm not using any internal designers, just straightforward single-parent stuff. This control draws a "header", so I'm trying to do three things: Have child controls dock to the bottom of the header ins...
I'm currently using winforms databinding to wire up a data editing form. I'm using the netTiers framework through CodeSmith to generate my data objects. For database fields that allow nulls it creates nullable types. I've found that using winforms databinding the controls won't bind properly to nullable types. I've seen solutions onl...
