• Game Technologies: DirectX, XNA, XACT, etc. getting variable from GameCompnent without instancing?

  how would you do this I'm not exactly sure what you're trying to do here. The only way you could get access to a variable from a class without instancing the class itself is to make the variable static and then either have a public static method to return the variable or make the variable public. The problem is, the variable itself wont be much use to you because it will be null as you haven't initialised it in the class constructor (or wherever else). The only way around this would be to create another public static method to initialise the variable or have the variable public and then assign it a value before you use it. Basically, it sounds like extremely bad programming. Why do you want to do it What exactly are you wanting to do ...Show All

• SQL Server Conditional Where using a Parameter

  How do I construct a select with a conditional where: If DefaultWH is not blank I want to add a "AND part". SELECT DISTINCT Name FROM Warehouse WHERE (Cono = @Company) CASE WHEN @DefaultWH' <> ' ' THEN AND (@DefaultWH = whseid) END Here is something that I have done. Rather than use a blank, set it to null and use an isnull. Example: If @DefaultWh = '' Begin Set @DefaultWh = NULL End Select Distinct Name from Warehouse Where (Cono = @Company) and isnull(@DefaultWH, WhseID) = WhseID Hope that helps! BobP ...Show All

• Visual Studio 2008 (Pre-release) ListView move items up and down

  I've got a ListView bound to an observable collection and I am able to move the items in the list programatically moving their index value in the list. But the selection is now a problem because the selection doesn't move with the item. What's the correct way of doing this This smells wrong to me too. I've opened a bug. I traced through this - ListCollectionView has all the information it needs to move currency along with the item and it's really simple for it to do the right thing; it just doesn't do it. Sorry about that. ...Show All

• Windows Forms Alternating between two images every 3 seconds using a timer

  Hello! I am quite new to C sharp and want to write a small program. I use an Mdi form with several child forms. I want to have a little picture box in a corner, possibly the Mdi form, that alternates every few seconds or so between two images continuously even while I switch between the various child forms. Is this even possible in Visual Studio 2005, and if so how Many thanks, Boombastic Just to ensure we are clear ... You can add the timer to the MDI parent. This would allow the event to be generated regardless of what is going on with the child forms. However, I don't know how you would *display* it on the MDI child form. Unless you wanted to put it as a background image of the MDI paren ...Show All

• SQL Server Queue not disabling

  HI There My activated proc is rolling back the transaction and putting the message abck on the queue infinately Normally it disabled the queue after a few rollbacks, i can see in the sql log that it just keeps rolling back and re-activating thousands of times.

• SQL Server Help Needed in writing a function to help daily nightmare with Debugging.

  I debug SPS on a daily basis and I use SQL profiler to help me trace where the problem is. Once I have established which SP is the main problem I need to debug the line of code. What I do is Cut and Paste the SQL Profiler details and populate all the parameters,sometimes that can be 30 and more.. Now what i thought is to write an SP or Function where I pass : SP name and Parameters that profiler genererates and returns me Declare Statements and Set Statements with parameters filled. EG Profiler Returns Customer_INSERT,20,'JO',BLOGG','5 LONDON ROAD' I would call my new SP =PopulateSPParams and cut and paste the profiler's string PopulateSPParams 'Customer_Insert,20,'JO',BLOGG','5 LONDON ROAD' this will RETURN THE FOLLOW ...Show All

• SQL Server deadlock victim

  Here is the exception I am getting, any idea why this might be happening: Exception: ThisMethod is done: let this go: Exception: Transaction (Process ID 74) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. Stack Trace: at Thanks for the reply. While users are working in the user interface I am inserting data to the table with another that is back end for the user interface. Although we do insert and update I do not think that user are dealing with the same data row, so I am assuming I should not be receiving deadlock. Does SQL server do RowLock or TableLock. How can I get my insert and update work on the Row ...Show All

• Visual C++ Visual Studio features - gone in later versions

  I'm trying to figure how to do certain things in a later version of Studio that I could do in VS6 but don't work anymore. Such as (a) dismiss the compilation output window just by hitting ESC, and (b) identifying the exact path to a given source file. I switched from 6 to .NET a couple of years ago, and have regretted not knowing how to make .NET behave like 6 in these particular areas. The Properties window - that's what I was missing. Thanks a million - that really helps! But sadly enough, the ESC key doesn't do for me what it does for you. Before I hit F7 to build, I have Solution Explorer (and now Properties) on the left and my code on the right. I hit F7, and the top half is taken o ...Show All

• .NET Development manual IL code fails verification with "unable to resolve token"

  Hi, I'm trying to write a (naive concept test) script that adds a prologue & epilogue to methods. It modifies the output of ildasm on an assembly to create a new IL file which I in turn compile with ilasm. It works by adding the following lines to the begining of every method: call class [Reflex]Reflex.ReflexWriter [Reflex]Reflex.ReflexWriter::get_Instance() callvirt instance void [Reflex]Reflex.ReflexWriter::Enter() It works on very simple assemblies I compiled with C#. To challenge my naive idea, I tried running it on the fxcop executable. The executable compiled but peverify fails with many similar errors, I copied the first one here: [IL]: Error: [D:\Program Files\Microsoft FxCop 1.35\FxCopy_trac ...Show All

• Visual Basic vb2003 - Database designer/diagrams where the heck are they?

  I've been perusing the VB helpfiles in 2003 and it talks about a database diagram and a database designer. If I right-click on the toolbar areas I can check both and get added icons for them which are ghosted, but I cannot figure out how to enable them. I have a database connection in the server explorer that works but seemingly no way to access either the diagram or the designer.

• SQL Server Failed to decrypt protected XML node "DTS:Password" with error 0x8009000B

After the public release I tried to uninstall the CTP-Versions to install the msdn finals but this time I got lost and was not able to satisfy the requirements of the final setup of VS2005.
