• SQL Server Layout File for a Fixed-Length Flat File

  Hi, Does the flat file connection format (Fixed Width) have anyway to include a file layout to define the columns.  We have different files which contain over a hundred columns. Or is there any other way to do this.  Script Component Thanks, Shanti If I understand the question, you want to have something like a format file that the flat file connection manager UI can read to create the files. We don't have a way to do that though we wanted to get it in. If you have hundreds of columns, I suggest writing a quick program that creates such a flat file connection manager using the ...Show All

• Visual C++ how to format a two or one digits number in a two char string?

  Ok, maybe this is a very stupid question but wich is the cleanest way to convert an int to a System::String with always at least 2 chars... Now, I do this: String* convertTo2CharString(int num){ if(num<10)   return String::Concat(S"0", Convert::ToString(int)); else   return Convert::ToString(int); } I suppose that with the String::Format, I can do it with one line of code but I don't know how. Tnx. Here's a good place to start for information on all the new stuff that's coming in Visual C++ 2005. http://msdn.microsoft.com/visualc/whidbey/ ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. PICKING OBJECTS by MOUSE doesnt work correctly

  Hello, I'm making a 3D game and I need to implement PICKING. But I've done everything as it is in the book and was also comparing code line by line with tutorial from other source http://www.toymaker.info/Games/html/picking.html and it doesn't work correctly - the picking RAY is somehow translated upper than it should be. I can click on the object a bit lower than it already is and i cannot click on it from the top, but a bit lower. Also I checked a sample from that book and I found out it does the same for it too. So pls, could you look at it: http://www.moon-labs.com/ml_book_samples.htm download - Download Part III Sampl ...Show All

• SQL Server Combine Data and Split into separate txt files for each header/detail row groupings

• .NET Development Just two true

  I noticed that true.ToString() Convert.ToString(true) Both return "True" rather than "true". Seems wrong to me somehow..... They both return (well Convert.ToString, simply calls Boolean.ToString()), either Boolean.TrueString or Boolean.FalseString depending on the value. I imagine if it returned 'false' or 'true', the Visual Basic programmers would probably say the same thing. ;) Note, though, that Boolean.TryParse does a case-insensitive comparision, so it will correctly parse either version. ...Show All

• Visual C++ Using DataGrid

  I've to change the values displayed in a datagrid (I mean I have to change the database). I watched in the code generated by the .NET, but it's ununderstable for me yet... Assuming you are using VS2005, right click on your datagrid and click on properties. Under the Data section, take a look at the DataBindings property and click advanced. I believe you can specify the source of your data there. If you are not using VC2005, you can probably still follow the same approach. Hope this helps!

• Software Development for Windows Vista Workflow state not persisting on Suspending

  I have added Sqlworkflowpersistance service to my windows host. But am not able to persist the state on Suspend() so on Resume() it is not able to fetch the workflow instance. State is not persisted when workflow is suspended. You can handle the WorkflowSuspended event and try to unload the workflow in the handler. However state is persisted automatically if workflow is Idle and you have set the flag UnloadOnIdle to true in the SqlWorkflowPersistenceService constructor. For unloading workflow on suspend, check methods OnWorkflowSuspend and UnloadWorkflow in following code snippet. class Program { stat ...Show All

• Visual C# separate classes

  hi, I want to separate group of classes to different library (dll) from main file, how can i do it thanks Visual Studio uses Projects as the unit of compilation, hence all files within a project would get compiled into either an Exe or Dll. Hence you use multiple projects to seperate out classes that need to be in a library vs classes that need to be in an application.

• Visual C# File Upload with restricted extensions not working

  I have a file upload class, and in it's constructor it needs to be able to take in an array of possible file extensions (using the new params keyword) I won't know how many or what extensions are being passed in, but once they are only those passed in are allowed to be uploaded. The class I'm having problems with inherits from it's parent class that works fine and doesn't restrict anything. The new inherited class compiles fine, but still allows anything to uploaded, even when I've specified ".doc" as the only type allowed. Here's how one would create and use it: UploadFileOptions  myUpload = new UploadFileOptions("C:\testfiles\", FileU ...Show All
