Debugging extensions in Visual Studio

To debug an extension in Visual Studio, script debugging has to be enabled in Internet Options. Proceed as follows:

1. Open the Control Panel.

2. Select Network and Internet>Internet Options.

3. In the Internet Options dialog, select the Advanced tab.

4. Make sure that the Disable script debugging (Other) box is deselected.

   

5. To make the execution of the extension break, add the statement debugger; anywhere in the JavaScript code. For example, the following causes Visual Studio to prompt for how to debug:

   Qv.AddExtension('QlikView/Examples/HtmlText', function() { debugger; <normal_extension_code> });

6. If Visual Studio is used for developing an extension, select to debug in that instance of Visual Studio, otherwise select a new instance.
