After having worked in WinForms for over a decade, the best features of a BindingSource that I like the most include: Binding … Read more
C# WebBrowser Control System.AccessViolationException
We have recently had a similar problem on the machines of several customers. The problem turned out to be a bug in the MSHTML control in certain environments. A common symptom for the problem seems to be the broken registration of the jscript.dll library. Symptoms that may help to diagnose if it’s the same problem … Read more
