• SQL Server Which Transformation to use

  Hi there, I want to check whether the values in a column within a defined list of values or not. These values aren't in a table or a file - I just want to "code" them in the package so to speak. I was thinking of using a script component but I'm not sure how to "fail" a row if it the column's value is not part of the pre-defined list. Any suggestions. Thanks. For fast performance, I expect coding the checks as a series of conditional operators in a Derived Column Tx would be the most efficient. For large lists, or more dynamic lists, putting them in a SQL table and usi ...Show All

• Visual C++ Tips for speeding up debugging (stepping through code)?

  I've got one particular large C++ project that, in VC 2005, when stepping through code in the debugger, it takes approximately 2 seconds for each hit of the F10 key (i.e. each line of code) to be executed. I've tried many things to attempt to speed it up: disable intellisense, renaming feacp.dll, removing all additional output windows, watch, breakpoints, etc, removing navigation bar from text editor window, disabling anti-virus on the machine, closing all other apps. It's always the same speed. Running on a dual P4 2.8 gig with 1 gig of memory, and hyperthreading enabled. Are there any other tips for speeding up debugging in the ...Show All

• Visual Basic Automating Excel - code doesn't execute on 2nd loop iteration

  Hello all. I have written code in VB.NET to automate Excel. This portion will copy a range on 1 sheet, find the last cell in a particular column on a 2nd sheet, paste the range and then sort the data so to remove any empty cells. The problem is that the code executes the first time in the loop (index = 0) but not the 2nd time although while stepping through it, it appears that it should work fine. It works for the 3rd iteration on to 15 or above, just not on the 2nd time it loops index = 1). I put break points in the code and all of the values appear to be set correctly and there is no error. What happens is that the code trys to activate ...Show All

• Visual Studio Express Editions BackgroundWorker Problems.

  Hello, I'm working on a simple app. that uses the GUI and 2 threads(backgroundWorker) to do some reading on some ports and to handle some alarms. The problem is that when ran on the target machine, it doesn't fire the update function, until it has finished or stopped. here's the basic function. 1- GUI loads. 2.- user configures the reader thread and starts the thread that keeps reading some ports. 3.- If the thread reads nothing, it updates with some progress, and if it reads something wrong, it updates with another progress (yes, I use the progress as status code, as there's no other way to do this with it... or is there a way ) 4. ...Show All

• .NET Development What Iam doing wrong?

  OK. What Iam doing wrong here I have wrote this function, but it doesen't work :S. ReadHTMLFile() is a function that reads whole HTML file. GenerateMenuBar() is a function to generate menu bar for the HTML file. Then I do what I need to do (is in WriteHTMLFile() function) and when I write the file I get a page like some tags are missing (truncated :S). I compare the html files (the original one and the generated one) and Ive notice that at the bottom of the file some tags are in very strange place (see below the code). public void WriteHTMLFile()         {          &nb ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotate the world

  Hi All How can I rotate the world in Managed DirectX using mouse drag and zooming using Scroll, like DirectX Viewer did Thx All The source code for DX Viewer is in the SDK. Its a C++ sample. Also a lot of the managed samples also do this using the ModelViewerCamera classes in the framework, take a look at that code to see how it works. Finally do some searches for 'arcball', this is probably the most common solution to the problem. However explaining the whole thing is too much for a forum post. ...Show All

• .NET Development Implementing Optimistic Concurrency Control using Datasets

  I have designed a data access layer in which all the updates happen using the data adapter.update(dataset) method. The problem I'm facing is that by default the 'Last In Wins' concurrency is being done. I mean the last update is potentially overwriting all the other updates done. The requirement is to implement an optimistic concurrency approach meaning that if two users A and B have datasets of table X and if User A updates the table X with his/her dataset before User B does, then in that case, when User B tries to update the table X, an error should be raised or no rows no should be updated since the actual data in the table X ...Show All
