Using Beyond Compare with visual studio

Beyond Compare is the best merge and compare tool I’ve ever had the pleasure of using but I have found the experience of integrating it with visual studio can depend greatly on using the right parameters.
Using a different merge/compare tool with visual studio is a fairly straight forward thing to do but if you’re using something like winmerge but beyond compare has a lot more bells and whistles to fiddle with. Below is my preferred setup.

How To:

Under Tools > Options > Source Control > Visual Studio Team Foundation Server

Select Configure User Tools. Add both Compare and Merge operations.

Beyond Compare

Compare:
   Tool: C:\Program Files (x86)\Beyond Compare 3\BCompare.exe
   Arguments: %1 %2 /title1=%6 /title2=%7 /solo
Merge:
   Tool: C:\Program Files (x86)\Beyond Compare 3\BCompare.exe
   Arguments: %1 %2 %3 %4 /title1=%6 /title2=%7 /title3=%8 /title4=%9 /solo

Visual Studio Hanging

Do get lots of hangs in Visual Studio where the window fails to redraw when scrolling, some windows don’t paint – and then VS finally hangs. It appears this is because you are hitting the default 10,000 GDI object per process limit. This seems to happen to me quiet often when viewing xaml files (in vs2008).

You can see the GDI Object count in Process Explorer or if Task Manager - by clicking on the view -> select columns menu and ticking GDI Objects.

You can't fix this as far as I know but you can delay the inevitable by increasing the limit.

See this link for information on how to change the GDIProcessHandleQuota limit in the registry: http://msdn.microsoft.com/en-us/library/ms724291(VS.85).aspx

I set the limit to 15,000 on my windows 7 64 bit desktop with 4 gig of ram and haven't had any issues.
