• .NET Development Database UPDATE problem.

  Just a question. Im really wondering why my sample database program wont update. It will say that it has updated the actual database but when i double check, it didnt. I am not using the command builder coz i want my own sql codes. When I test using the query builder, i will see the data being updated or added but when i use my own program, it really wont. Actually i have this one sample database program that updates ok. I just dont know why I cant do it again. Im really pissed off thinking abt it the whole night. I ommitted the INSERT and DELETE commands since they dont work too. h ...Show All

• SQL Server if/else newbie question (conditionalizing SELECT on old/new db, existence/abscence of a column)

  As to not get lost in the details of my problem, I'm oversimplifying this posting to get the root of my problem answered. :-) Let's say a database has a table called CUSTOMERS , and it may or may not contain a column called ORDER_NUMBER , depending on whether or not the database is an old or new database. Now if I run the following query in Query Analyzer (v8)... if (1=2) begin select * from CUSTOMERS where ORDER_NUMBER is not null end ...I get "Invalid column name 'ORDER_NUMBER'." Obviously 1 does not equal 2, so why is the code in that if block being executed Or is there some sort of precompilation/schema che ...Show All

• .NET Development technical differences between JVM and CLR?

  I read lots of things about jvm and clr but still i can't understand the technical differences.Much of them are about "c# is more powerful than java" or  "c# is copy of java" etc..(some benchmark tests). But i want to learn the techinical and algorithmic differences between these two technologies.I don't want to learn which technology is more powerful.I want only technical details. How do they execute source codes differently step by step I mean ;what are the different  ways(methods) which they use while execution. Your help is greatly appreciated.

• Visual Studio Document Explorer crashes

  Thought I'd start a new thread, since I'm using Visual C# Express, rather than full VS2005. Windows XP Pro SP2, Visual Studio 2003 Pro, SQL Server 2000 Developer Edition, Visual C# Express, Visual Web Developer Express, SQL Express 2005, MSDE. I also have Virtual Server 2005 SP1 beta installed. Problem just started this weekend. Whenever I click on any topic in the Index, Document Explorer crashes. I've tried Repair on Visual C# Express, Visual Web Developer Express and MSDN 2005 Express. Same problem. It was working fine last week, I'm not sure what's changed. I have previously had VS2005 beta2 installed, but I removed that by following the ...Show All

• Software Development for Windows Vista Rehydration and member variables

  Hello, In some of the samples found in the book "Presenting Windows Workflow Foundation", member variables are used to allow activities to share some data.  For example the book used a member variable that is incremend inside a while loop using a code activity.  The value of this member variable is important to the proper execution of the workflow, but doesn't belong to a particular activity.  If the runtime decides to dehydrate a workflow, what happens to these member variables when the workflow is rehyrdated   Are they somehow automatically tracked and rehydrated to the proper value when the workflow resumes Than ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX Area inside a CLR/WFA or MFC window?

  Hello! I'd like to write an application which should use DirectX, but not in the whole window, only a part of the window. In the other parts of the window there should be buttons and input areas to controll what is happening inside the DirectX area. So appart of the DirectX part, that looks like a normal CLR windows forms application or a MFC application. My questions are: Is it possible to include such a DirectX area in a windows forms application or MFC application (Is windows forms application better for this than MFC or the other way round ) How can I include this area in a windows forms application or MFC application Are there some sa ...Show All

• SQL Server Stopping and restarting Transactional Replication

  The situation is as follows: Database A is being replicated to database B on a networked server. The application vendor is in the process of doing customizations which require frequent table changes. So the vendor (who has access to the replicated DB) stops replication in order to upgrade some tables. But I am finding that either he has forgotten to restart replication or, more than likely, has broken it. So, if anyone is able to comment on a process which will allow changes to database tables and the restoration of replication, I would be very grateful. thanks in advance. Why is the vendor stopping repl ...Show All
