JavaScript Debugging in a Web Browser Control with Visual Studio



Debugging a Web Browser Control embedded in a Windows application can be a bear because there's no obvious way to debug the the JavaScript code or HTML DOM/CSS inside of the application. Although the Web Browser uses the Internet Explorer Engine for HTML rendering and JavaScript execution and provides most of the engine features, the Debugger and F12 are not part of that. As it turns out you can use Visual Studio to hook up a script debugger and provide a rich debugging experience with the full IE debugger, Console and even a DOM/CSS Explorer. In this post I show how.

Dragging and Dropping Images and Files into the Web Browser Control



Dragging content into the Web Browser control and capturing the content dropped can be tricky. The Web Browser Control is based on Internet Explorer and is actually an ActiveX control hosted inside of a container and because of that is difficult to deal with. In this post I describe how you can get around this issue and still capture images and files dropped on the control and handle the drop operations.

Debugging the Web Browser Control with FireBug



If you need to debug JavaScript code or layout issues in a Web Browser control inside of a Windows desktop application, you've probably found that the experience sucks. Although Internet Explorer on which the control is based suppports rich developer tools, those are not available in the Web Browser control. Enter an oldie but goodie: FireBug which is an embeddable Console implementation that provides a lot of the features that you find in modern browser developer tools and with a couple of lines of html you can add this debugger into your application.
