• Visual C# Losing value after calling method for use with another

  I am trying to figure out why JAAAlbum.ProductID is null when passed to my AddNewProductRelationship_Album_Track method in my loop http: / / www. webfound. net/ forum_ posts/ addproduct. txt Basicaly what's happening is the AddNewProduct is called for the album and JAAlbum product is created then values are saved to the database with the following lines: JAAlbum.Save(1, TransactionAbstraction.GetTransaction()) ; TransactionAbstraction.CommitTransaction (); That's all fine and dandy but the problem is when it hits the if statement again, it then goes to add the track: AddNewProduct(xl, row, host, fileExtWAV, "Track", filePathSourceWAV, fileName, moveFile, sstore); Problem is line 131. I get an error saying JAAlbum.Produ ...Show All

• .NET Development Debugging Web Service with database connection saved in Application session state variable

  I'm debugging a web service app that has a database connection stored in an application session state variable. When I finish a debugging session and then start a new one the database connection object still exists in the application variable from the previous debug session. Is there a way I can clean up objects stored in application variables before I start a new debugging session Thanks I think I know what's going on. I don't have exception handling in place yet. So when the app bombs the connection is still open (no try/catch/finally code yet to close the connection!!!). Thus when I start another debug session the previous DB connection is still open and I try to open it again, a no no. ...Show All

• .NET Development Is it possible to compare strong name evidences from a calling assembly with the current assembly?

• .NET Development version question

  There is a note in the help description in a few places that reads "Note: this namespace, class, or member is supported only in version 1.1 of the .Net Framework." What does this mean Does it mean that it was not supported in the earlier version but is supported in version 1.1 and will be in the future Or does it mean that it is supported in only the version 1.1, not in earlier versions and will not be supported in future versions The one that prompted my question is the "HasRows" property of the DataReader. I have noticed the note in other places as well but can't now remember where. The issue is important because I don't want to write code that is guaranteed to fail in future versions. ...Show All

• Software Development for Windows Vista c# VFW capVideoStreamCallback(...) (DIB) lpVHdr To Bitmap

  Hi, (Update - previous post stated capSetCallbackOnFrame(..) this was an error sorry for any confusion, the call back being used is capVideoStreamCallback(...)) Im using the old VFW (Video for windows) within a c# application to facilitate video capture, partially throught the excellent ezVidCap control, (activeX wrapper for VFW capture) and due to some unfortunate limitations the win32 API. It is required that the preview runs, whilst recording and that a frame may be captured from the video stream at any time, ie recording, or not recording. ezVidCap will not allow or facilitate frame capture whilst recording but does make available the call back capVideoStreamCallback (). During recording I am using the callback function capSetCal ...Show All

• Software Development for Windows Vista Designer re-hosting and custom activities inside xoml-> NullReferenceException during GetRootActivity()

  Currently I'm trying to re-host the workflow designer, who's not ;) But I'm failling with each mdsn code sample when I try to load a custom xoml workflow. I end up with a NullReferenceException during the GetRootActivity() method or I see an empy diagram showing nothing but emptyness ;( I know that there is TypeLoader service available, I've added my assembly to this typeloader before the WorkflowLoader tries to load (create instance of) the workflow and it's custom written activities. I would like to load a xoml based workflow with custom activites inside the rehosted designer, what am I missing Thanks Hi Kushal, That's not possible due to copyright rules in my company.

• .NET Development General question......about differece btw language and technology

  Hi All, I have one general question............sorry to put in this forum................. I want to know the difference between language and technology........... eg .net is a technology and C# is a language....... what to say for HTML so I want a line that differentiate btw these two terms......... This sounds like a semantic issue. Let's say we accept the definition of technology as application of scientific/engineering knowlege.  With that, a programming language can be a technology.  SmallTalk can be called an implementation of OO software development technology.  .NET framework can be called an implementation of VM technology, but then .NET also has a central programming language of ...Show All
