• Piotr Trojanowski ODBC

  I am a relative newbie to the ways of .NET. I have been learning to use Microsoft Visual C# .NET 2005 and have wrestled just about everything to the floor except for database access. I have an extensive survey data library with all the files in dBase IV format. As a long time Delphi programmer, this used to be a relatively straightforward piece of the jigsaw and I have written a number of successful applications that manipulate those files. ...Show All

• Bogey1 Making dataset instances invisible to COM

  Hi There, I've got a C# assembly that's marked for COM Interop Registration. It contans a dataset definition. When I look at the TLB file generated for the assembly, the object is included.

I could mark the ...Show All

• Ales Is NET Framework fast enough?

  I want to make a MIDI-editor, but I'm not sure if using NET Framework is the right choice. I'll need really fast editors, like fast ListBoxes and fast ComboBoxes, that need to be updated the fastest possible. I've make a comparison between how fast does a Win32 application adds 1000 items to a ComboBox, and how fast does a NET Framework does it. The Win32 application is about 5 times faster!. So, what do you suggest me Is there perhaps a way to ...Show All
