Visual Studio QT integration
The Debugger deffinitions define types for the Visual Studio debugger. Therefore the content of data types like QString QDate or other core QT datatypes is displayed in a Visual Studio debug session.

Installation
Make a backup of the original file (!!!).
The only file we are talking here about, is the
autoexp.dat
file. It is stored in
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Packages\Debugger

Now, there are two cases you need to be aware of.

Case 1
The first case is if the file is untouched, therefore it is the original version installed with Visual Studio.
In that case, you can just replace your lokal file with the one from the ZIP archive.

Case 2
The second case is, if this file was modified by a VS addin or another installation process.
In that case, you have to use the .patch file and apply the two parts to your current version of the autoexp.dat file manually.

Paste the first part of the File to the end of the [AutoExpand] group. For normal you find the end of that group by Searching for a line wich starts with [Visualizer] and paste the code before that line.

The second part of the patch file needs to be pasted at the end of the [Visualizer] group. For normal you find the end of the group by searching for a line wich start with [hresult]. Now paste the code before the [hresult] line.
