• Visual C# Creating an Excel in C# having 60 columns and 6000 Rows is taking 20 minutes

  Hi, I am trying to create an Excel file using C#. But I am facing a performance issue. It is taking about 20 minutes to create a 1.5 MB Excel file. And for the 20 minutes, the Server's CPU is being used 100%. I have also tried to optimize the logic. I am using only 2 major for loops. Is this normal for a generation of a huge (60 cols*6000rows) Excel spreadsheet having static data without any logic written to it, to take 20 mins of 100% CPU If so, please give me a link to such an online resource so that I can have some online material for my support. OR Is the code still needs to be optimised. Please help me out in fixing this issue. Thank you in advance. Thanks and Regards, Neelesh ...Show All

• SQL Server Easy NOOB question

  Hi, I'm trying to pass a parameter into a procedure and not getting the results I want.  There's probably better ways to write the procedure, and if you want to suggest one, that's ok, but I'm most interested in just getting the stupid thing to work.  I'm trying to search a bit field in a table with the bit field being the parameter that isn't working.  In the code I include below, @category is the parameter that isn't working.  For this case, "category" is a bit field in a table and I want to be able to pass in different fields and find out if they're set.  When I use the parameter @category, the result isn't right.  If I hard code the field name (for the case below, "Compensation" is the DB field name), i ...Show All

• Windows Forms datagridview cell selecting

  hi, i have a datagrigview with columnheader and rowheader . the default behaviour for the topleftcell click is to select all cells. is there a way to bypass this functionality ( none cells selected ) or to disable that cell thanks You can just make the mydatagridview.rowheadervisible = false; You wont have the row header, but will still have column headers, and that wont happen anymore, becasue there is no row header to click. Now if you want the rowheader and the column header both displayed, but do not want the full row to be selected when you click on the row header, you may be able to call mydatagridview.clear or it might be called clearselection. If that doesnt work the only thing i c ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Generating MipMaps

  Hi, When I create a texture using the code below the mip maps always come out as a solid color, how can i generate proper mip maps from the texture TextureImage = new Texture (device, ii.Width, ii.Height, 5 , Usage .None, format, Pool .Managed); SurfaceLoader .FromSurface(TextureImage.GetSurfaceLevel(0), textureTexture.GetSurfaceLevel(0), Filter .None, 0); TextureImage.GenerateMipSubLevels(); Thanks for any help, -Dave You are a victim of a common misunderstanding what GenerateMipSubLevels do. It is only there to create the mip maps for textures that are used as render target. And even then they need to create with special parameters. The function you are looking fo ...Show All

• Smart Device Development HELP! DataReceived/SerialPort Troubles

  I am building code for the PocketPC to interface with a chemical sensor to poll and report on chemical agents in the air. I am having a devil of a time getting the DataReceived event to pass content (through an Invoke) to the main thread. When I write an "N" to the device, it is supposed to send back the following string to the UI, which represents the chemical sensor types that are housed in the unit: "CO VOC H2S LEL OXY" When I send an "R" to the device, it is supposed to send the current readings for each of the sensors as a string that looks like this: "00000 00000 00000 00000 00207". I have all of this working successfully as a WIN32 application, but it doesn't port cleanly to the .NET 2 ...Show All

• Visual Studio Tools for Office Catching Unhandled Exceptions

  Hi, I am trying to catch unhandled exceptions in my code for a c# workbook. I have tried using the: AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(HandleException); (this is set in the ThisWorkbook_Startup method) but my HandleException method is never called and i get the default "Office document customistation is not available" error message. This isn't ideal as the customisation breaks and stops working, I'd like to handle the exception myself and carry on. The workaround is to put try catches on all my code but handling the unhandled exception would be better. The exceptions only ever tend to be network timeouts, but occasionally something else goes wrong. Thanks ...Show All
