• Visual C# How many threads should a process possess?

  Hi, everyone: My application runs with its thread number ranging from 40 to more 60. I wonder how many threads a windows process should have. I have checked a lot only to find that the general MaxThreadNumber for ThreadPool is "25". But how about threads created by Thread.Start Further more, after Thread.Start() was executed in my application, I was surprised to find the the thread may remain "Unstarted" under a uncertain condition which brings about a hang-up. Does this happen just because of too many threads in my application Thank you I don't claim to be an expert on threading, so please forgive my ignorance on the subject. I have read a lot of material about the dos and do ...Show All

• Visual Studio About the Compability between .Net and COM object

  I am currently working on inhouse libraries upgrade from .Net 1.0 to 2.0. In the .Net 1.0 libraries we have used COM object Craxdrt.dll and functions like craxdrt.AddPictureObject, craxdrt.AddTextObject. I would like to ask if there are any alternatives in .Net version, or I still have to use the COM object for compability. Using craxdrt.dll (Report designer component, RDC) is not even supported in the .Net 1.0 libraries let alone the 2.0. It is only supported through COM languages, and is being deprecated. The new way to do it is through the RAS SDK which requires Business Objects Enterprise or Crystal Reports Server, and if you are using Visual Studio 2005 you need the XI release 2 version of these pr ...Show All

• Visual Studio 2008 (Pre-release) Problem using XPath to investigate Message Headers.

  I am having what appears to be a strange problem. My goal was to use XPath to investigate custom headers in a message. I would create an XPathDocument by passing it an XmlReader from the message.Headers.GetReaderAtHeader() method. Now, if I try to use an XPathNavigator and it's select methods on a Message object that was created by the WCF stack, it doesn't work. If I create a Message (the same EXACT message) via Message.CreateMessage(...) using a string representation of the SOAP message, the XPath queries work fine. I know why its not working, but not sure if its a bug or if there is a reason behind it. The Message instance that is built by the WCF stack is a BufferedMessage instance while that returned by Message.CreateMessage(...) i ...Show All

• SQL Server No New Data Source Option in SSAS

  I have just installed a new instance of SQL Server 2005 including Analysis Services. I have created a new Analysis Services database and assigned a role with full rights. However, I do not have the option to create a Data Source. Clicking the right mouse button only shows refresh. I am new to SSAS and any advice would be appreciated. You are probably working in SQL Server Management Studio. Choose SQL Server BI-Developer Studio instead and start an Analysis Services 9.0 project.

• Silverlight (formerly WPF/E) WPF/E (TextBlock) is not rendering Unicode correctly

  I have downloaded the WPF/E CTP & SDK, I played with them and have noticed that WPF/E does not fully support Unicode, as I use a TextBlock to test the display of Arabic text, WPF/E was rendering the text incorrectly as if it is rendering the text from left to right while it should render the text from right to left. This same behavior is true for Hebrew too which is also a right-to-left language. Hello Fayez, I tried also that and it did not work. I would expect full language support from MS soon hopefully. it is a must if they want it to pick up fully.
