• SQL Server sysxlogins table and null names

  Hi all, running sql server 2000 sp4, viewing the sysxlogins table data, and am wondering about the three items listed with a <NULL> in the name column, all xstatus = 192, each has a unique srvid value of 0, 2 or 3. Looking in the MS tables reference book did not help they don't cover sysxlogins, googled around but no luck, searched this forum also. What are these entries Thx I only have one entry for that. I assume that this are internal account which are us for internal purposes, these accounts have setupadmin and sysadmins rights (xstatus 192), dedicated to the (as of the srvid) local se ...Show All

  Hello. I installed VisualStudio.NET 2005 a few days ago.  ( not beta ) While I'm debugging, I'm faced with strange message box. -- MessageBox -- No symbols are loaded for any call stack frame.

• SQL Server For Each in SQL?

  Hi. using SQL Server 2000 here. What I want to do is pretty much execute a stored procedure, giving it the value of a field. The thing is, since I am still learning SQL, I am new to this and have no idea how it should be done.... The way this has to be is, execute a query (SELECT someField FROM SomeTable) then, foreach record for this someField column, I want to be able to get the someField value, and give it to a stored proc as a parameter (EXEC sp_whatever @p1) how would I achieve this is this possible First off, this is generally a bad idea if you can avoid it. Most of the time if you can rewrite it to whe ...Show All

• Visual Studio Referencing Properties that contain free form XML

  If you have a property group with a property that contains free form XML and you want to reference the value, of say, OutputPath, what is the syntax for doing so $(ConfigOptions) gives you the entire XML string, as you would expect. I'd like to get to the CodePath within $(ConfigOptions). I played around with a few variations, but none seemed to work. Are free form XML properties only intended for logging and tasks that actually know how to parse the XML string contained in the top node Thanks for any input you can provide. < PropertyGroup >    <Config Options >       < OutputPat ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. ShadowMap HLSL render loop woes

  Below is a portion of my render loop. It uses the ShadowMap.fx file from the ShadowMap sample. If I remove the code in blue (comment it out), the shader and loop works fine (scene and shadows are the way I want them). If I add the code in blue (uncomment), then my objects no longer show, only the background appears. Is there anything blatantly obvious wrong with the code in blue // Clear the render target and the zbuffer device.Clear( ClearFlags .ZBuffer | ClearFlags .Target, unchecked (( int )0x8C003F3F), 1.0f, 0); try { device.BeginScene(); beginSceneCalled = true ; VertexDeclaration vd = device.VertexDeclar ...Show All

• Architecture General business object requirements

  For those of you who have worked on medium to large sized projects, or anyone who has an opinion , I would like to know what types of logic an application needs in the business layer. If the objects expose properties and collections, is a simple validation on write all that's needed I guess the objects also have methods that do various things. If anyone feels like offering any insight into the kinds of things their business objects do besides store bits of information that would be greatly appreciated. I'd also like to know what types of exceptions are generally thrown when persisting to a database. What about errors in the middle of bat ...Show All

• Visual Studio Express Editions ComboBox.ObjectCollection.IsReadOnly Property

  Hi, How do I set the combo box to read only. I have found a topic on this using the, ComboBox.ObjectCollection.IsReadOnly Property, but not sure how to code this. Ron I assume what you want to do is to force the user to pick only certain selections rather than just typing in what she thinks is appropriate. Set the DropdownStyle property to "DropDownList" and populate the Items property with the choices you'll accept. ...Show All

• Visual Studio Memory leaks in the automation?

  I'm using the automation to build up screens in visual studio using vb.net. After building 800 some screens (all in the same project mind you) the machine gets dog slow. Well upon looking at it, its using almost 1GB of RAM and the machine only has 512MB physically. Thats fine, but 1GB of RAM used seems excessive. I'm making sure to close the form after I created it. (my first attempt didnt do that and caused the system to run out of window handles. :) Generally, I would say that there is something not being freed and we have a classic memory leak. Given that I'm using a .net language however, I dont really have any control of the memory, so ...Show All

• Visual C# Using Excel to graph?

  I have a database and I've spent some time trying to get Crystal Reports to graph some information from it in the way I want it but haven't had much luck at all. Is there a way to use Excel to do graphing and then somehow get those graphs onto a windows form in C# I've seen some posts about importing data into Excel and I suppose I could try to do things that way but it would be inreadibly useful if I could just let the user get all the graphs from the program I'm building itself.

• Visual C# ?porting to VC++?

  I have heard about ppl doing it but how can it be done, im guess porting vc++ to C# would be a nice trick to know how to do. can someone explain or point me into a direction of where I can read about it. thanks We've looked at C++ to C# conversion (in depth) and unfortunately at this time we feel that there are too many subtleties and loose ends for a C++ to C# converter to be useful.  The amount of work you would have to do in post-conversion cleanup would be so large that you may be better off doing it by hand.  This is why you may never find a good C++ to C# converter (or even a bad one).
