• .NET Development Reading a DataReader from two places at the same time.

  I have a SqlDataReader which returns some data from a database. I would like to insert the data from this DataReader into two different tables on two different servers, using two SqlBulkCopy instances. Somehow my SqlBulkCopy objects should read the same DataReader in parallel, so I won't have to read my data twice from the source. The amount of data is quite large, so I wouldn't cache them, for example into a DataSet. How would you solve this problem The only idea I could think of is creating a wrapper over the DataReader, which implements the IDataReader interface, and which can be read in parallel from two different threads. However I don't know how this would perform, as each thread would block after each row of data, and th ...Show All

• Visual C++ Help button get chm instead of hlp

  I have a application built around a CPropertySheet derived class. The help button is looking for 'app.hlp' file (this is the default MFC stuff, I've not added anything other than moving the button). How do I get it to look for a 'app.chm' file instead I've tried the following using a test help file in InitInstance() //First free the string allocated by MFC at CWinApp startup. //The string is allocated before InitInstance is called. free((void*)m_pszHelpFilePath); //Change the name of the .HLP file. //The CWinApp destructor will free the memory. m_pszHelpFilePath=_tcsdup(_T("C:\\filezilla\\filezilla.chm"));     EnableHtmlHelp(); but i just get "Failed to launch help" Actually in the ...Show All

• Visual Studio 2008 (Pre-release) Code-Generated Base Entity Class

  Hey team, Is there a way to specify the base-class that the generated entities inherit when the code is generated I'm thinking of creating a base-class that contains common functionality, and want to have the generated classes derrive from that instead of System.Data.Objects.Entity. My base-class will of course extend System.Data.Objects.Entity. :) Thanks!

• Game Technologies: DirectX, XNA, XACT, etc. Using DirectX with VB.Net

  I am using Visual Studio 2005 (VB.Net) to write my apps. My next app will have a graphical component (nothing as intricate as games) but still lines and shapes will need to be displayed interactively. My questions are: Can one use DirectX with VB.Net If so, which SDK do one use. If not, what would be recommended to program graphics using VB.Net.

• SQL Server How to fail when ForEach File Enumerator doesn't see files

  I have a ForEach file enumerator that executes a data flow for every source file in a specified directory. If there are no files in the directory, the package executes with a result code of 0. I need the package to fail if there aren't any files found in the specified load directory. Is there a simple way to do this with the SSIS component, or will I have to script the entire file enumeration process inside script tasks to handle this requirement Thanks in advance for any assistance with this question. Please post replies to this forum. -Doug First thought, how about setting a variable to False before the loop, and within the loop to True. You could then use a Script Task after the loop that dep ...Show All

• Visual Basic 1st time lucky, 2nd time's good, 3 times through and it crashes.

  I have a program that uses a subroutine that has an output file called temp.csv. It also has a sub that reads the output file using a streamreader, then closes the streamreader, I've watched it, and it always closes, even when I get an error. Every time through it deletes the temp file because in the output sub, it appends to the output file otherwise. When I run the program, and the program tries to delete the temp file, no problems, second time, no problems, third time, I get the another process is using this file... exception. Like I said, the streamreader is closed by this point every time, I've watched it. Any thoughts Well... Even though I had close statements in there, and it was closed, apparantly ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Performace: can't this thing draw any faster?

  I'm certain that I my code must have some critical inefficiency somewhere; I can run my favorite 3D video games at maximum settings, but my little DX app slows down to < 90 frames per second when it tries to draw 100 little boxes. Here's the code in a nutshell: protected D3D.Texture _texture; protected static D3D.Sprite _sprite; _texture = MakeTexture(); // ends up producing a 1x1 white texture _sprite = new D3D.Sprite(graphics); dx_graphics.BeginScene(); for (int i = 0; i < 100; ++i) { _sprite.Begin(D3D.SpriteFlags.AlphaBlend); _sprite.Draw(_texture, new Rectangle(0, 0, (int)500, (int)500), new Vector3(0.0f, 0.0f, 0.0f), new Vector3((int)300, (int)200, 0.0f), Color.FromArgb(255, 255, 255, 255)); _sprite.End(); } dx_graph ...Show All

• Smart Device Development Generate DTMF on SmartPhone/PocketPC via C# at runtime

• Visual C# Placing a filter on Image

  Hi all, I am a beginner in C# but somehow it is required of me to use C# to create a presentable GUI that will place a movable filter on to an image. I did post a different topic previously however, I thought that someone might be able to help me better, if I describe the task at hand in more detail. What I wish to do is load an image to a picturebox. Then place black plane with a circular hole of a specified radius. So the final picture will be only viewable via this little hole and everything else will be black. Now this hole needs to traverse line by line such that at the end the whole image would have been presented to the user. The time it takes to traverse to the end should be made variable. I thought of doing the above task by ...Show All
