ASP in IIS7 error line number is not allowed to solve the problem

In Win7 to do ASP development, found a very egg pain problem. When the error occurs, the line number is not allowed, it is difficult to quickly read locate the problem code (in the Win2003 IIS6 is no problem). The name code has only dozens of lines, the error line number is thousands of lines (should IIS7 the ASP all include code to a file at runtime), as shown in figure:

After looking at the ASP configuration in IIS7, we found that there is an option to calculate line numbers, set to true. (Note: Click on the right side of the application, although the prompt is effective, but actually did not take effect.) You must restart IIS with IISReset before it can take effect.
