I fill the DGV by looping through a dataset and adding a DGV row for each datarow. After this the DGV.RowCount = DataSet.Rows.Count. Funny thing is that the DGV shows only a part of it (19 of 2448 in my example). After some testing I figured out that the rows show up if I change the Window size a bit. So now I use a work-around by inclu...

I am wondering if there is a way to dynamically redefine an ICommand-derived class's CanExecute method. I'm still new to .NET and perhap...

I have several medium-sized data sets in-memory that I need to be able to filter and find information from quickly. The data sets are small enough that I don't want to take the performance hit of going to a database every time I need an entry but large enough that I really need to index the data somehow. Currently, I'm using POCO object...

This is very odd. We have some managed C++ (an assembly) which uses a .NET COM interop dll generated by TlbImp to make calls into a COM object. When we register the COM DLL we specify that we want it to execute within a surrogate (the "DLLSurrogate" registry entry). Our COM DLL is 64-bit and is executing on a 64-bit platform. When we ...
