• Visual Studio 2008 (Pre-release) WCF call fails sometime in CAB application

  We are currently developing a software using both CAB (Composite Application Block) and WCF. The client side GUI is written based on CAB. However, it is found that if WCF callback is used, sometime WCF client side call will raise "TimeoutException" exception. I have checked the WCF log file and found that before the exception was raised, the message was already received by the client side; but for some reason, the message was not processed until timeout. If I not to use CAB, it seems everything works fine. I think a dead lock could be generated by ObjectBuilder, which is the main part of all the application blocks. I have wrote a small test program which has the exactly same problem. I cannot locate the problem precisely ...Show All

• Windows Forms Multi language help please

  how can i add a combo box were people select the language they want and it will transform it al into that selected language any help is appreciated thank you hi It seems that there is a bug related to the resource manager: http://dotgnu.org/pipermail/pnet-developers/2003-December/000844.html The reasons are: 1) ResourceManager uses CultureInfo.CurrentCulture, but it should use CultureInfo.CurrentUICulture instead. 2) The CultureInfo.CurrentCulture and CultureInfo.CurrentUICulture getters should make an indirection to the Thread. So, the problem is that while the Thread now has the correct culture, the Resource manager does not update the values on the screen what you could do is the follow ...Show All

• Windows Forms another System.Windows.Forms.HScrollBar question

  hi, i noticed that the System.Windows.Forms.HScrollBar renders a little differently from the scroll bars that are present on a control with the AutoScroll property set to true. The difference is in the way the arrow buttons render, or maybe i should say, don't render. when pressed they just disappear. with the autoscroll version they are rendered as a pressed button shaded a tad darker. what gives thanks, scott hi, now i spent some time duplicating this and looking for the difference between my working implementation and my duplicated implementation. i said earlier that i could not duplicate the problem, today i was able to. here is what did: create a simple form with hor and ver scroll bars from the to ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Device inside a content processor?

  Is it possible to get the graphics device inside the content processor, to create vertex buffers, etc. Yes, but you don't need a device to do that. The ContentTypeWriter for your type should write out VertexBufferContent and IndexCollection types. Then, when reading them back in using your ContentTypeReader, let XNA create 'real' vertex & index buffers. You won't need a device to create VertexBufferContent or IndexCollection types, which is nice because that happens off-line anyways. Write like: output.WriteObject< VertexBufferContent >(value.BuildVertexBuffer()); output.WriteObject< IndexCollection >(value.BuildIndexCollection()); and read like: VertexBuffer vertexBuff ...Show All

• SQL Server which one is effective ?

  which one is effective(performance vice) in stored procedure 1) Creating a table object and destroying it after using or 2) by using the temp table(#tablename) which one is effective.. Thanks in advance... It depends on size of your data.. Table Variables For simple data the best method is using the Table varaibles (@Variable as Table) Disadvantage  You can't share accross the Scope or on nested SPs Advantage  Stored in the Memory instead of Disk, it will reduce the Disk IO (not fully it may use Disk IO)  Scope specific & Concurrent support Temp tables For Complex & huge data it always better to use the Temp Tables (#Table), it will be faster than the Table variables if the row s ...Show All

• Visual Studio Team System Command line get changeset

  HI How do I get the latest changesetnumber for a specific file and parse that number to a get command I know I can get the number with 'tf history...' but how do I parse that to the get command 'tf get /version:C[changesetnumber]...' Regards Kim Hi What I want is to build my solution, using scripts, until we convert it all to tfsbuild. I have a include file called version.rc that contains the versionnumber. Before the build starts I check out and edit this number, and do a checkin. To be sure no one do a checkin in the same second, I would like to get the latest changenumber on version.rc and then use that changeset number to get the rest, to be sure I have a correct and wellknown ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to detect version of D3DX installed?

  With the newer versions of DirectX there are several different D3DX dlls that exist. Just checking for DirectX version 9.0c is not sufficent as that version contains several revisions of the D3DX dlls. If a game ships with the April release the earlier versions of DirectX 9.0c will not work. How can the exact installed version be determined So, apparently there is no way to determine the version using DxDiag What about file version of d3d9.dll I was thinking of checking that. I guess there is no harm in just looking for the D3DX9_30.dll but it just seems like the DxDiag should support this. ...Show All

• Smart Device Development Getting the calling application path

  Hi, Is there anyway of finding the application name from a class I'm trying to build a configuration setting class (like the one in the full framework). It all works fine if it is called from the application .exe but if I call it from a class which has been created by the exe it does not work. The reason being that I get the path of the calling assembly and then add .Config to it get the settings file eg assemblyPath = Assembly .GetCallingAssembly().GetName().CodeBase; configFileURL = assemblyPath + FILE_EXT; Is there any other way of getting the application filename, either through a specific method or by walking up the call stack.
