• .NET Development Unsubscribing to events from COM Client doesn't work

  I've created a .Net component that has a COM interface. This interface contains events. I've also got a VB6 client that connects to this component. It recieves the events using the VB6 WithEvents "mechanism". Setting the WithEvents variable in VB6 to nothing doesn't make the events stop fireing. Looking deeper into the problem I see that the IConnectionPoint->UnAdvise call that the VB6 client makes when setting the WithEvents variable to nothing fails with error code 0x80040200. The problem gets worse if I set the WithEvents variable to a different object, since the first object still fires events, even if I have no reference to it anymore. I get the same result using VB.Net as C# to create the component. Is thi ...Show All

• SQL Server Truncate and foreign keys

• Software Development for Windows Vista Holder-of-Key vs. Bearer

  Until recently I was under the impression that the holder-of-key confirmation would be mandatory in CardSpace aka InfoCard. E.g. the Technical Reference for InfoCard v1.0 in Windows states on p. 5: " The subject confirmation method is always specified as “holder of key” and is identified by the URI “urn:oasis:names:tc:SAML:1.0:cm:holder-of-key” . ". There are also other references to this property e.g. http://www.identityblog.com/codesample.php simple-infocard-demo/signed_token I also saw this value when test-driving InfoCard with self-issued cards against service provider demos such as https://infocard.pingidentity.com/sp/login.jsp After updating my test environment to the .NET Framework 3.0 Runtime Components Ju ...Show All

• Visual C# Implementing an expression parser

  Hi All, First of all thanks you very much for spending your time to open this post. We are trying to implement a small parser which evaluates expression given by users. We have idenfied a set of operators, functions, keywords, conditional staments which are required for the language. Can you please tell us how shall we implement a parser which checks syntax of the expression and evalutes them If you have any reference to data structure concepts, please let me know. Many thanks in advance. Cheers, Gopi Sounds like you're trying to build an interpreter. If you're new to the subject, read some articles on languages and grammars. It's not an easy subject. First you'll have to build a tokenize ...Show All

• Visual Studio Express Editions How to I make this change?

  Hello I need some help. Say I have a connect button, and when you push it it would say "Trying to connect." and after it timesout, it would say "Could not connect." dose anyone know how to do that That would help me so much! - Thanks well you would implement a timer, drag and drop a timer on your form and set the interval for the time out (interval is measured in milliseconds, so 1 second = 1000 milliseconds). Double click the timer to make a tick event so when the time has elapsed, this event would fire/be raised Now when you press this button, you simply start the timer: Me.theTimer.Start() Me.theLabel.Text = "Trying to connect..." now in the timer tic ...Show All

• SQL Server ETL, simple database mode and a large log file

  All, I have a ETL host database (40 gig) that is running in simple mode, but is generating rather large log files (10 gig). Are these large log files due to the bulk load nature of the ETL process, and if so, how can I mitigate the issue (reduce log size) without specifically shrinking the database Any help is appreciated... Jim You will need to break up the load into smaller chunks. If the entire load is a single transaction, the log will have to grow to accommodate changes, just in case the transaction fails and it has to rollback. If you're using bcp/bulk insert, take a look at batchsize option. ...Show All
