FIX: Cannot Set Breakpoint if Project Contains \C++\ in Path

Article ID: 122170

Article Last Modified on 10/17/2003

The Integrated Debugger, when used with:
- Microsoft Visual C++ 2.0 Professional Edition

This article was previously published under Q122170

SYMPTOMS

The debugger is unable to set breakpoints when you use the Visual C++ integrated debugger to debug a project located in a directory that contains non-alphanumeric characters (for example, a path that contains \C++\) -- which is a directory name supported by the Windows NT File System (NTFS).

It is possible to set a breakpoint in a source file, but attempting to start a debug session generates this error message:

The breakpoint "{,test.cpp,}.linenum" cannot be set

Here test.cpp is the source file and linenum is the line number where the breakpoint is set.

CAUSE

The integrated debugger can't handle file names supported only on NTFS.

RESOLUTION

Avoid the use of NTFS-specific file names or directory names.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was fixed in Microsoft Visual C++, 32-bit Edition, version 4.0.

MORE INFORMATION

Steps to Reproduce Problem

Create an MFC AppWizard project. When placing the project in a directory, give a directory name that contains special characters (for example, C++).
Build the project for debug mode.
Place a breakpoint on a line of code in your project.
Press the F5 key. A dialog box should appear that reads, "The breakpoint ... cannot be set."
