Sql Server Compact Edition

26 January 2010 brianbruff

I've been playing with a workflow service hosted here /PSService/PSService.svc
Feel free to give it a bash [August 2012, removed]) Endpoint is using basic http binding.

Tonight I whipped a Sql Server Compact Database out of another little app I have lying around so I could sit it behind the webservice persist data.

But

To my horror it doesn't work..

I get the following exception " sql compact is not intended for asp.net development"

I can imagine why I guess.. bit what a pity.. it's not allowed..

[August 2012: It is allowed, just needs a setting]

WPF Routed events

Ever have a control on a window and want to be able to receive button clicks from this child control?
More than one I've done this the hard way, but now.....

 

[code:c#]

public VariablesWindow()
  {
   this.InitializeComponent();
   variables.AddHandler(Button.ClickEvent, new RoutedEventHandler(HandleChildClick));
  }
  
  private void HandleChildClick(object sender, RoutedEventArgs args)
        {
            Button senderButton = args.OriginalSource as Button;
            if (senderButton != null && senderButton.Content != null)
            {
                string buttonText = senderButton.Content as string;
                if (buttonText == "_Cancel")
                {
                    this.DialogResult = false;
                    Close();
                }
                else if (buttonText == "_OK")
                {
                    this.DialogResult = true;
                    Close();
                }
            }
        }
