Just saw this post by Jan Schreuder talking about MSDN Virtual Labs . If you haven't checked these out yet, it's worth it. Without installing the software, try out various Microsoft technologies, both present and future. If you were just dying to try out that new SQL Server 2005 feature, or find out...
I just received an anonymous comment to the Blogger version of the Data validation in .Net using ErrorProvider and DataSet errors post, asking for the code to setFocusToErrorOnRow.

When an unhandled exceptions occurs (or application ThreadException), the user is presented with a dialog prompting them to submit it as a crash report. The dialog in turn calls a web...

It seemed easy enough - just call SelectNextControl to have .Net read the tab order and select the next one in order, right? Yes, it was that...
Here's a post from Dec. 11, 2004: Recently I encountered a challenging situation in Windows Forms where I needed to sort the contents of a ComboBox involved in the middle of multiple levels of Data Binding. The combobox was on a window that provided a list of items on the top of the window, and details...
