What is private bytes, virtual bytes, working set?
The short answer to this question is that none of these values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak. Private Bytes refer to the amount of memory that the process executable has asked for – not necessarily … Read more
Debugging with command-line parameters in Visual Studio
Yes, it’s in the Debugging section of the properties page of the project. In Visual Studio since 2008: right-click the project, choose Properties, go to the Debugging section — there is a box for “Command Arguments”. (Tip: not solution, but project).
