    monitoring a third party server

    No, it is not in the registry. I have a couple of these. They stream live price data into excel. The one I need to monitor was written in Java, and I do have documentation for its methods. Without a ProgID, however, I have no idea how to capture it in a com. Can anyone help point me in the...

    DDE links

    Live Data

    I want to store the info in an sql server database. I do not know how to get the data directly into sql. Right now I am gathering the data in excel, and then using DTS to populate the table. I am sure that there is a better way of doing this, I just don't know how.

    OStream

    I have been using the wrox series of books, starting with begining C++ through Professional ATL COM Programming. The is also information in the MSDN knowledge base. To get you at least started, on the menu of C++ use file, and new. Not the icon. You will get a dialog box. On the project...

    OStream

    Now you are talking about automation. It is a whole different ball game. You need either a MFC project, or an ATL project with MFC support. You need to use MFC it import the appropriate library as a class. Then you can invoke the methods. Let me know if you need more info.

    How do I find out what is causing an exception?

    I wrote a com in vc++ to execute an excel spreadsheet every minute. This spreadsheet also uses an add-in that is a DDE link. It works well, except that intermittently I get an excel unknown exception, and excel terminates. This happens ever 1 to 2 hours. Does anyone know how I can find out...

    Access Violation when a COM returns

    Thanks, but I found the bug. I had gotten too hung up with the ATL stuff and I forgot the basics. My array indicies in the functions were incorrect.

    Access Violation when a COM returns

    I have an Excel spreadsheet with a lot of data. This data needs to be crunched, and returned to the sheet so graphs can be created. To accomplish this I wrote a ATL COM in C++ 6.0. To manipulate the data, from the main function I call private void functions and passes the data through...
