<p>Basically what I want to do it this: a pdb file contains a location of source files (e.g. <code>C:\dev\proj1\helloworld.cs</code>). Is it possible to modify that pdb file so that it contains a different location (e.g. <code>\more\differenter\location\proj1\helloworld.cs</code>)?</p>
| <p>You can use the source indexing feature of the Debugging Tools for Windows, which will save references to the appropriate revisions of the files in your source repository as an alternate stream in the PDB file.</p>
| <p>It is certainly possible, as On Freund has already pointed out.
But if it is only so that the sources can be located and loaded during debugging, then a better way would be to set the source path correspondingly. Once set in a debugger, it will preemt all hard coded paths inside PDBs.</p>

<p>Is there any way to change the background color of the Solution Explorer in Visual Studio using a Theme? - or any other way for that matter?</p>
<p>I can change it by changing windows-wide color settings, but obviously that affects too much.</p>
| <p>Just created VS extension for that in under an hour, search extension manager for "SExColor". Enjoy ;)</p>
| <p>Not by any means of configuration from Visual Studio itself.</p>
<p>You can however probably "hack" the window object from the Win32 API (look up "window enumeration"). Once you have the window handle, you can set all characterstics you want.</p>

| <p>I'm not sure if this is the correct way but you could add another non nullable term to the index (say BookIsPublished) with a default value and if no search term is entered by the user return all matching items on the BookIsPublished constant field.</p>
