• Visual Studio Express Editions Textbox updating/refresh problem.

  Hello Experts, This problem is actually making me ill, please could you spare a moment The answer is probably very simple (I just can't find it!). I have a form with an API event handling a price feed. The feed is just trying to update a textbox on the main form. Code is like Public Class MainDisplayForm . . . End Class Public Class PriceFeedFromAPI Inherits fxRateEvent . . . Public Overrides Sub handle( ByVal ei As fxEventInfo, ByVal em As fxEventManager) . . . MainDisplayForm.PriceTextBox.Text = CurrentPrice.ToString End Class The text box TextUpdate event fires OK after the update and I can see that the value gets to the .Text property (it Debug.Prints the value when fired) but ...Show All

• Software Development for Windows Vista Why do WF and WPF have different DependencyObject classes?

  I was surprised that the Workflow and Presentation Foundation frameworks each have their own DependencyObject- and related classes. I was expecting that in the final bits the dependency object functionality would be represented by one unified set of classes. What drove Workflow to define its own set of classes in System.Workflow.ComponentModel, rather than using the classes in System.Windows Thanks, Glenn Burnside Thanks,Tom. That's pretty much what I suspected happened, but I was really hoping there was some solid technical reason instead. Any chance of seeing a unified set of classes in the Framework 3.5 timeframe Thanks, Glenn Burnside ...Show All

• SQL Server Keeping Multiple Detail Lines in a Table Together

  I have a table in my report. The table has two detail lines per detail item. My problem is that the two lines really need to be kept together, and the table will page break between the lines when the end of page is reached. I have been looking through the different table properties, and I have not been able to locate anything that lends a hand to my issue. I did some quick searches, and I couldn't find another thread requesting this information. I may just be missing something obvious. Any help and/or advice would be great! Thanks. Curtis P.S. This is what I am working with Detail 1 = Product Description, Product Number Detail 2 = Various Pricing and Units of Measure, Barcode It makes it a little difficult if these two ...Show All

• Visual Studio Team System Import Database Schema error: Cannot sort a row of size 8132, which is greater than the allowable maximum of 8094.

  The error message is clear enough. To understand the problem, let's start the initial discussion with a description of the original database in question. The database has two tables that were at the maximum row size and everything was fine. After adding constraints to the database, those two tables ended up exceeding the maximum row size as these warning messages indicate: Warning: The table 'Table1' has been created but its maximum row size (8065) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.

• Software Development for Windows Vista ScardAccessStartedEvent does not signal in Vista services - service hardening?

  Dear all, Migrating our core development platform to Windows Vista, one of our Windows services using smartcards is failing. We have debugged the problem and found that the event provided by the function ScardAccessStartedEvent does not receive notification. This event is supposed to signal when the SmartCard Resource Manager starts. As we have a WaitForSingleObject(event,INFINITE), the service hungs. Testing the same service as an ordinary executable ( registering with -regserver ) I can see it works properly. In XP it works properly both as an executable and service. I have read something about Service Hardening in Vista and I guess it may be caused by privilege reduction. So, I've created some code to enumerate the existing ...Show All
