• .NET Development CreateParameter give bad performance

  We are working with MSSQL 2005 and ado.net framework 1 .1 During our performance tests over large DB (~1M records) I found out that when I run one of our queries, with embeded values in the query -string, instead of using the CreateParametr method, the query ran 40 times faster!!! The parameters are 2 strings (~30 characters) , the type in database is varchar(255). Wh at can cause such a huge difference in the execution time This is our AddParameter source: public void AddParameter( object parameterValue) { string paramName; IDataParameter IParam; //For string that is empty do nothing means null is entered to field. if (((parameterValue is string ) && (parameterValue.ToString( ...Show All

• Software Development for Windows Vista Windows Workflow Foundation BRE Does Not Update Value Type Fields of a Structure

  The BRE of WF does not appear to update value type fields that are part of a structure. When the THEN action of a rule is executed and a calculation updates a value type in a struct, the value of the structure member remains zero. Turning on tracing of the execution of individual business rules shows successful execution of the assignments, but the targeted field maintains its initial value of zero during its use in subsequent calculations. No exceptions are thrown and tipping the BRE via the "update()" command has no impact on this behavior. In my case, changing the struct to a class cured the BRE of this ailment. Sorry you ran into this. We are aware of this issue and will be fixing it in the next release. Unfortunately, ...Show All

• .NET Development CLR and thread deadlocks

  Hello, I'm hosting the CLR (.NET 2.0) in an unmanaged C++ app. The CLR is used for calling C# plugin functions through IDispatch. The C# plugins are COM visible classes and are created from the app main UI thread. They are mostly used for accessing the app through a COM primary interop assembly generated with TLBIMP.EXE. The interop between C# and the app is achieved through the default Microsoft COM wrappers. This is all working fine but I'm having a problem when the C# functions are called by the app from a worker thread. At this point the CLR attempts to interop with the app via the UI main thread which is causing a deadlock because that thread is locked while the worker thread is executing. From what I see in the call stack (b ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 360 Boat game with source

  Hello I was playing about again the last 4 days and come up with a little boat game for the 360. The source code is very untidy but there might be something of use in there for some people. It was written for use on the 360, it might work ok for the PC. You can have 1 to 4 players and it uses some ai for the others. There's only 1 track at the moment - I may get around to fixing it all up into a proper game if there's enough interest or if an artist wants to help out. It plays a different sound effect when you cross the line and beat your own best score. My best lap is 8.07 (no down to a 7.96) seconds.   Best to use a 360 pad but here's some keys if you feel the need.   Q and E change the number of players ...Show All

• Visual C++ Adding Resource data to an executeable without an RSRC section

  Hello,I am currently stuck on a problem. I am trying to add an Icon to an external executeable.Meaning: a executeable, which I don't have control of the original source. Now I'm trying to add an Icon as resource to this executeable, but this doesn't work using the standart APIs "BeginUpdateResource", "UpdateResource", "EndUpdateResource". As they don't seem to add the resource table.I hope anyone knows how to get rid of this problem.I'm pretty sure it is possible, as I saw it "Resource Hacker" for example.

• Visual Studio Syntax error when using Online MSDN

  Hi, I have a problem with the Visual Studio 2005 help. Every page that loads i get a "line 1 syntax error" message box. It is DRIVING ME INSANE! I have tried to repair of the Document Explorer tool. I have looked for updates or KB articles and i can't find anything. I have tried turning off IE debugging but just the shape of the message box changes (and it doesn't ask me to debug), and the syntax error moves to line 2. A sample source for the page starts with XML so i thought that might be the cause but I am running the latest updates. Has anyone else had this problem Thanks in advance for any tips, Nathan Hi!

• SQL Server Deserialization failed: The type initializer for 'Microsoft.ReportDesigner.Drawing.RptStyleConstValue' threw an exception

  The way we resolved this was by deleting the user's NTuser.dat file and having them log back on to create a new NTuser.dat file. This is not painless in that the user then has to reconfigure Outlook, recreate shortcuts on the desktop, etc., but it's better than reloading the OS. ...Show All

• Visual C++ How to convert 4 types of C++ strings?

  I am new to C++ programming ... and it seems not everything is written in the books. Can anybody explain to me how to convert between the 4 types of string representations: char * char[ ] string class String ^ class Are there simple recipes for conversions Are the classes string and String^ only used with Microsoft C++, or with ANSI C++ as well It would be wonderful to get a sort of systematic overview, which I could not find in any book anywhere so far.
