exception - wpf DoDragDrop IndexOutOfRangeException -

-

I have found this solution that I am trying to implement drag and drop behavior among a group of ListViews Uses full properties:

But whenever I try to drag and drop, I get the following error message in the debug log:

My 'xx The first chance of type 'System.IndexOutOrRangeException' occurred in '

exception I tracked it down and it You can see that DragDrop.DoDragDrop is running, but since the exception has just been swallowed, I do not know where this code is being thrown away from. How can I find the exception?

The main problem with my problem was that I do not know how to break the Visual Studio when An exception was thrown within the WPF code because I was doing drag and drop operations, this can be done under the debug menu in Visual Studio:

debug -> exception -> exception Locate it that you are interested in and click on the checkbox to make the debugger breakdown exception The expertise.

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
