    My Visual studio debug sessions are suddenly behaving erratically. The debugger position does not correspond with the c++ source code line, it's sometimes one line off. This used to work fine. I'm VS 2005 SP1. Any ideas what might be wrong?

    Hi, I am just giving a try.... May be your exe hasn't been updated, with the current code and debugging points.Its a old one What you can do is, - check the exe path in project settings...see if it is existing, check the updated time(after re-building) - or, delete the exe...rebuild the project..if no new exe has been updated to that path, that means your path is wrong....

      No, that's not it. I'm just going to try to reinstall and see if that does the trick.

          Have you removed all temporary files, including the Debug folder, and rebuilt the project?

            This may be too simple a solution but what you describe usually occurs when you start debugging a release version. Is your active configuration 'Debug' ? Souldrift

              The standard solution to this problem is to select "Rebuild Solution" in Visual Studio. Sometimes the source gets out of sync with the stored debugging information, and Rebuild Solution brings it up to date.

                    Yeah, that's the first thing I tried. But I notice when I moved the function that I was debugging to a different position in the file that the problem went away. Seems like VS just doesn't like my source code

                      hi, it may be cause of fault in encoding of lines endings in Your source file, ie. from any reason at end of line instead of standard windows CRLF code ('\x0D','\x0A') appear the CR code ('\x0D'). Debugger counts line endings and if any encoding of line end differs from the other it may results in wrong line highlighting. To eliminate this problem You can use any text tool that can re-encode the line endings in Your source file to standard windows encoding or You can use Visual Studio editor feature "Save With Encoding" into "Save File As..." dialog. I would try first in VS do "Save File As..." -> Unix/Macintosh and next "Save File As..." -> Windows.

                        You know I have a switch statement like this: switch (keyCode) { case 0x10: maybe it's somehow recognising the 0x10 as a new line return. That makes sense becuase it's only after this switch statement that the error occurs

                            What about optimizations?

                              The code after that switch statement is giving the error, so it definately looks like it to me

                                Sorry for my mistake, proper hex values of CRLF are: '\x0D' for CR and '\x0A' for LF. Values which I wrote earlier are related decimal values 13 and 10 respectively. I was thinking about hex values but wrote decimal :) it happens. In Your switch condition there is actually decimal value of 16 but not 10 as You expected. So, it not may be the cause of problem.
