• .NET Development Database access and threading

  I have begun experimenting with remoting, databases, and threading, and have come across a potential problem. My current self-assigned project is a chat system, similar in nature to MSN Messenger. The problem arises whenever two clients are talking to the server at the same time. For example, the registration process involves sending a email address to the server. The server checks that this email is not already registered (in the database), and if not, adds it to the database. However, the registration process on the server side is performed using threads, and however rare it may be, I can envisage a problem arising... For instance, see this example. The two columns represent two 'registration' threads running concurrently on the serve ...Show All

• Visual Basic Image viewer in VB

  Hello, I’m trying to build a sort of an image viewer in VB for an Excel macro. My idea was to have an user form with a "previous" and "next" buttons that browsed through images in a directory and displayed them in an image box above, something like the windows image viewer, but much simpler. Does anyone have any idea how I can go about doing that Thanks a lot. I've thrown together a quicky .Net example for you (it uses the same mechanism that Katana314 described), but it's been too long since I worked with Excel-VBA to know whether this code will work as a macro - probably not entirely, but you may be able to adapt it. ...Show All

• .NET Development GetRunningObjectTable in .NET 2.0

  Apparently GetRunningObjectTable is a new supported method in .NET 2.0. It is accessible via IBindCtx.GetRunningObjectTable and the signature is given as... void GetRunningObjectTable ( out IRunningObjectTable pprot ) Which of course implies that IBindCtx is a supported .NET 2.0 interface too. This is good. We don't have to bother with all that tedious P/Invoke stuff. So... ... does anyone have any ideas on how to get hold of the .NET 2.0 object that implements IBindCtx (because the MSDN certainly doesn't give us any clues!) Cheers, ~swg Well, that's fair enough. If there's no managed object then there isn't. Thanks for the info. Re: your final comment, I didn't draw the conclusion that there ...Show All
