debugging

问题 I use Visual Studio 2005 & C#. In my FormClosing event I release some resources, that my application uses.

问题 I was trying to debug a multi-threaded process on a Linux server running Slackware 12 using GDB 6.6.

问题 I'm debugging R code with browser(). The function pauses the execution of the current R script and allows for inspection. Is it possible to enable/disable the debug mode on the fly, during the execution? With large scripts it would be very handy. Thanks 回答1: Your question prompted me to read ?browser . The documentation says you can use the expr= argument to browser to create (the illusion) of conditional debugging. That, combined with a global option should give you what you want. foo <-

问题 I'm using VS 2008 on a 64-bit XP machine. I'm debugging a 32-bit C++ DLL via a console program. The DLL and EXE projects are contained in the same SLN so that I can modify the DLL as I test. What happens is that every once in a while I kill the program with Debug | Stop Debugging (Shift-F5). VS stops the program, but the console window stays open! If I'm sitting at a breakpoint and hit Shift-F5, it will terminate properly, but if the program is running full-tilt when I stop it, I often see

The tooltip only appears when I hover over the element with my mouse pointer. Normally I'd just inspect the html or dig deeper with Chrome's developer console, but as soon as I do that the tooltip disappears because the mouseover event ends.

问题 In pdb (or ipdb) we can execute statements and evaluate expressions with the ! or p commands: p expression Evaluate the expression in the current context and print its value. [!]statement Execute the (one-line) statement in the context of the current stack frame. The exclamation point can be omitted unless the first word of the statement resembles a debugger command.
