      • Hi all, in the following C++ code, I'm defining a class inside an unnamed namespace. This works as expected, but I'm having trouble setting a breakpoint in the Foo constructor. Well, I can navigate to the code and set a breakpoint by clicking on the line containing the code, but I can't seem to find the right way of specifying the breakpoint location by name. I tried "Foo::Foo" and thing

A concrete question: since Spy++ shows, that this window receives all WM_KEYDOWN messages but the trac

      • Sometimes for no apparent reason "find in files" does not search at all. It says something like "no files found". Pressing Ctrl-ScrollLock fixes the problem and find in files works again. I could never figure out the purpose of this "feature" and when it disables "find in files". The same annoying bug/feature exists in VS 6 and VS 2005. If I invoke "fin
