Visual studio debug - set a condition on a particular variable

[leejwen]

I'm using VS 2005 under WINDOWS to debug a piece of code. Can I set a breakpoint based on a variable's value. For example, I have a variable IFC. I want to find out where IFC is set to 5.

Another question: could somebody tell me where I can find a best tutorial about how to use Visual Studio debug.

Set the breakpoint, then in breakpoints window, in right-click context menu, 'condition' item.

You can set a watch expression. That is you can watch a variable and have the program breaks without setting a break point in code.

However that generally makes things run very slowly in deed because the debugger has to check the variable value after every instruction. If you can use a break point with a condition set on it.

Sorry for the confusion. Actually, I want the debug to be stopped automatically where the variable IFC=5, for example. Is it possible to set a condition? This program is huge with lots functions while IFC is a global variable. :-)

Many thanks
