How about strings? How can I set a condition on a string variable, e.g. I want to stop when strTmp == "User3"?

Great post Sara. The white "+" is also in VS2005, but it only shows up when using the "Is True" option.

around since 2005? Mind you, I think Turbo C++ 2.0 already had conditional breakpoints circa 1988. And Visual C++ 4.1 (The first version I used) for sure had them.

The + is indeed a nice cosmetic... plus.

Thanks! I wish I would've known about this one a long time ago! FWIW, the white '+' is in 2005.

FYI, the white "+" is present in VS 2005 as well. Cheers!

Hi everyone,

Remember to use == for a comparison, not just a single =. I spent ages trying to figure out how one of my variables was being updated! :)

I have VS2008Express... i only get two options when i right click a breakpoint - disable and remove.

Is this not in express? or only in express SP1?

Shouldn't it really be "You can make breakpoints conditional?".

A "conditional breakpoint" would be more like the ability to get the program to break when a condition is met at whatever line it happens on. Unfortunately, breakpoints must be set on a particular line, not a condition.

For example, I would like to set a breakpoint when a button on my form changed it's .enabled property to False, but I don't know when that happens (have many statements that can change it).

Maybe the next VS version?

Thanks for the great tips though!!

Anastasio, you can set data breakpoints in VC++ (break when this variable changes, break when this address changes), not sure about about form control properties.

This is quite useful but be wary that the way this works is you still actually hit a breakpoint long enough for the expression to be evaluated by the debugger. This is important when you deal with code that is in a tight loop as it will be incredibly slow ...

To work around this you will tend to have to write your conditional right into your code.

This is useful, but unfortunately it's not a complete solution. What's missing is the ability to break when a certain condition is true on the line that caused it to be true. Sometimes I spend a long time trying to figure out who changes a static variable. It would be nice to just say, "whenever this condition is met, stop the program and show me who did it."

Visual C++ had this feature ages ago!
