• SQL Server Multiple Multicast

  I have a dataflow where each row passes through about 20 validations. This data flow could contain 200,000 to 20 million rows. Initially I set it up with a multicast component sending data each of the validations. This got to be pretty messy. Then I thought about using several multicast to subdivide the validations and make the data flow easier to follow. I tested using two multicasts to see if it would affect the performance of the dataflow. Results were inconclusive. Before I continue adding and testing different multicast configurations, I thought I would check here to see if anyone else has tried and measured this Thanks for any insight you can provide. Opinions vary, and rightly so, abou ...Show All

• Windows Forms Giving Focus to the Tab Control

  Hello,    I have a tab control with 2 tabPages in it for data entry. The second tabPage is information that the user does NOT have to fill out - so I give them the option. But if they do want to fill it out, I have a button at the end of tabPage 1 for them to proceed to that 2nd tabPage. What code do I need to add in this button_click event that will automatically give focus to that 2nd tabPage so that the user doesn't have to click on the tab PS I tried this - but it didn't work... Private void button3_Click( object sender, EventArgs e) {      if (tabPage2.Focus() != true )      tabPage2.Select(); } Thanks! Any help would be great! pps I just n ...Show All

Can you help me a little The structure of target file is as follows. abc: 100 def: 888 ghi: a.log jkl: 0 mno: c:\123.txt Thinking about the effect made by "/t". the structure of file looks like follows. abc:\t100 def:\t888 ghi:\ta.log jkl:\t0 mno:\tc:\123.txt I wanna update the content followed by "jkl\t", 0 to 5555.

• Visual C++ Syntax for Overriding IListSource -Managed C++

  I am having trouble with the syntax for overriding IList source in managed c++. Especially, how do you override the public ref class StopListSource : Component, IListSource { private: static BindingList<String^>^ blah = gcnew BindingList<String^>(); public: StopListSource() {} StopListSource(IContainer^ container) { container->Add(this); } //***The Following generates: a member using-declaration or access declaration is illegal within a managed type IListSource::ContainsListCollection { get { return false; } } //Not sure about the following, but it doesn't throw any errors //in C# this is: System.Collections.IList IListSource.GetList() , but in C++ this is old syntax ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creating a Menu in 3D, Modify Vertexes & Textures

  hi there! i'm new in game programming (begun 2 months ago) and, after having created the basis for a Turn-based strategy game i've encountered major problems in calculating line of sight and range of view for my characters. I've also had problem with a map editor then i've decided to move to XNA. Now i've more complicated problems :) 1: i've just created a 3D map editor. A 40x40 tile based map that i can modify. I can rise, lower and flatten my terrain but it requires a lot of times because i must redefine my vertexbuffer everytime i modify my map. Is there another way How can i send only my modified vertex information to the GPU 2) in my map, if a tile's inclination is > 45 degrees,another texture is assigned to ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. ExternalReference<CompiledShader> - Am I missing something?

  I'm trying to create references to .fx files from my Content Pipeline types (my writer). When I build my level objects, I want the references to textures and effect files to be baked into the object so that you don't have to add .fx and .png files to your project, just add the file that processes into a level. (A .bsp in my case). My problem is that I used this thread to create external references to textures, but the same technique does not work for shaders. Psuedo code in the processor: ExternalReference<EffectContent> source = new ExternalReference<EffectContent>("C:\shader.fx"); ExternalReference<CompiledShader> built = context.BuildAsset<CompiledShader>(source, typeof(EffectProcessor).Name); ...Show All

• Windows Forms System.IO.FileNotFoundException In Windows Application

  Hello! I have developed a windows Application using VS2003 (VB.NET) to enable my client to export Crystal Reports 8.0 to PDF,HTML and Excel formats. Since the Excel export that comes with VS.NET is not very user friendly, I used Interop.CRAXDRT.dll reference to export the reports to Excel. The application workes fine on my workstation, but when the client installed it, he is getting *** System.IO.FileNotFoundException: File or assembly name Interop.CRAXDRT, or one of its dependencies, was not found**** error. I have tried everything I can think of to resolve this in vain. The interop.craxdrt.dll is in the application bin folder. I made the client copy the file to his system32 folder.

• Visual Studio Crystal Reports XI and Visual Studios 2005 Questions?

  OK I have read a lot of post here that lead me to believe CRXI is not compatible with Visual Studio 2005. Or should I say not till CRXI r2 comes out in which case it will support VS2005 .net Framework 2.0. On a Project that is updated to VS2005 from VS2003 and CRXI for the most part went very smooth.   Except and for me this is major CR Version is 10.2.3600.0 in VS2005 where as it was VS2003 it is Version 11.0.3300.0 for me. Ok from all the post I understand this has dumbed down my reports since CRXI is not ready for VS2005 till r2. In the mean time should we just use the dumb down version of our reports I have seen a lot of post that indicate people can not do this do to controls, processes, or design of there certain proj ...Show All

• .NET Development Delay in invoking webservice call

  hi, We are noticing the huge delay once we invoke the asynchronous call to web service to get the response back, not able to find the reason for the same so far. Is there way we can debug and find the root cause of this delay in invoking web service and getting the response from web service Thank You Ganga What we did is we put trace log at the last line of code in Webservice where data is sent to UI process as "Exit" and first line in UI as "Entry" and we see time difference of 40 seconds waiting for webservice to return to UI process and this is consistent.

• Visual Studio 2008 (Pre-release) Media Element Will Not Play. (And general installation issues)

  I tracked the error down with the on failed error, and I THINK this is ther error: Insufficient memory to continue the execution of the program. I can only say think so because the routed events confuse me somewhat. I looked at your install you didn't mention installing WIC (per section 2.1 of the readme). I had to install WIC even on a fresh install leading me to believe that you have to install WIC regardless of whether or not you upgraded to the June CTP or installed it fresh.
