• SQL Server deadlock errors

  I'm setting up a push merge replication, after the initial merge agent completes without errors I move the subscriber from a wired connection to a wireless connection. At this point I get an error… The schema script …Program Files\Microsoft SQL Server\MSSQL\REPLDATA\unc\[ table ]_93.sch' could not be propagated to the subscriber. (Source: Merge Replication Provider (Agent); Error number: -2147201001) Cannot drop the table '[ table ]' because it is being used for replication. (Source: dfdmfvltgh09 (Data source); Error number: 3724) After this error the initial merge agent kicks off again trying to apply the initial snapshot where I then get the following deadlock errors.

• Visual Basic Any way to BREAK when MyVariable=CertainValue? on ANY line?

  In VB6 (or 3, I forget;-) you could BREAK when a variable reached a certain value or changed, no matter where that change occurred. In VB.net 2005, it seems that you can only do that for a particular line. (I.e., Break on Line X when MyVariable=MyValue). Am I missing something This seems to be a HUGE step backward in debugging functionality. You can still do that in VS2005 with memory breakpoints, but it only works for C++. The reason behind is that variables are now managed by the garbage and thus can be reallocated or moved during the execution of the program. If you wrap access to your variable via a property accessor, then you could still catch the condition by setting up the conditional breakpoint ...Show All

• Visual Basic Class not registered

  I just transferred an app from one computer to another and upgraded from VS 2002 to VS 2005. After doing this, I'm getting several errors, the most common one being: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). The error occurs on the line that says InitializeComponent() at the end of the region "Window Form Designer generated code" for one of my forms.

• Software Development for Windows Vista Domain Model/WF Design Question

  This question is very design-oriented. One thing I'm having trouble with is knowing where WF fits in a domain model. For example, is WF intended to provide the logic backing for a domain model, or replace a domain model Meaning, is it recommended that we still design domain entities (e.g. a class named 'Invoice' with a behavior/method named 'Cancel()') and use WF to implement the logic, or is WF supposed to supplant the need for behavior-rich domain entities. In particular, many systems have situations where the business logic is relatively simple, and could readily be defined with a WF (where it seems to be overkill) and other situations where the behaviors are complex and long-running, where WF makes sense. Should we mix models Thanks ...Show All

• Visual Studio 2008 (Pre-release) multiple databases using sqlmetal

  Currently, we are replicating from a file system database and are not able to include foreign key constraints. Therefore, we created a model database with the same table structures and added the foreign key constraints. With this database, I use an O/R mapping tool to create my dll. I am trying to do the same thing with sqlmetal. I created the cs file and when I try to pass a different connection string than the one used to create the cs file, I am getting an error when I try to bind the object to the grid. I am getting an InvalidCastException on .DataBind() Please let me know what you think Thanks, Joe ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Need Info On The Basics

  OK, Ive read a large part of this forum and HAVE recieved alot of answers. With that said, over the past few days Ive been burshing up on my old C++ skills and plan to start learning C# here in the next week. My plan is to do this as a Hobby (Mainly cause Im an electrician with a family) so ive set some really long goals. Im not expecting to pump out a 3d game in a year. Ive been very interested in writing code for years now and have been a lover of Game design ever since Missle Command came out in the Arcade (Just Dated Myself). Since Ive taken this up, a Tattoo Artist buddy of mine has become interested inthe graphic end of the whole thing. So in short, what would be a great 3D design software for a begineer (with years of drawing expert ...Show All

  For security, I have to disable bluetooth and wireless in pocket PC of our employee, and I have to via REGEDIT. How do I disable bluetooth via REGEDIT and how do I disable wireless via REGEDIT Thank you. IMHO you can't do this _just_ with Regedit. What you can do is hide the individual control panel applets - simply add a string value named "Redirect" below the key e.g. [HKEY_LOCAL_MACHINE\ControlPanel\Bluetooth] Then soft reset the device.
