C# Container like the VB Collection??? code-frog15-Mar-07 6:34 code-frog 15-Mar-07 6:34  Years ago (1998) I wrote an MTS application that had a C++/ATL middleware and a VB 6.0 front-end. I remember an object (Collection) that you could stuff unique values into. It would throw an error if your values were not unique. You could trap the error and continue adding values. What made it nice is you didn't have to manually iterate the data structure checking for uniqueness before inserting your values. Does C# have such a data structure? I can write one but if there's an intrinsic structure that takes a key, value pair that would be great. Anybody know of such a beast?

Then you insert the value if it does not already exist.

Doesn't any collection implementing IDictionary give you what you want? If you try to add an element whose key already exists in the dictionary, an ArgumentException is thrown...

By convention I try to avoid causing any type of error as a means of correct programming so I've never tried this. I'll let you know what I find out.

Re: FTP to Mainframe jchigg200019-Mar-07 13:49 jchigg2000 19-Mar-07 13:49  Hey, thanks for the suggestion. Too bad I've already done countless "Simple Google or Code Project" searches and found that this class is completely useless. Not to worry...I have gotten the wininet.dll command function working. one backgroundworker, two jobs? brainfuelmedia_15-Mar-07 5:19 brainfuelmedia_ 15-Mar-07 5:19  Is it possible to have one backgroundworker complete one job, then move on to another completely different job all in the same class? If so, how? Thanks! Re: one backgroundworker, two jobs? Judah Gabriel Himango15-Mar-07 5:45 Judah Gabriel Himango 15-Mar-07 5:45  No, not without any coding. You could easily modify the BackgroundWorker to support such a thing. Fortunately for you, someone's already done this: QueuedBackgroundWorker component[^].
