Question : Unable to set break point

Why does this happen after running the project, and setting the breakpoint while the program is running:?

I get a message:

The following breakpoint cannot be set:  .....
The common language runtime was unable to set the breakpoint.

set the "generate debuging information" to true in project properties



or

manually edit .vbproj file to change the debug symbols to true
