The information in this article applies to:
- The Visual Workbench Integrated Debugger included with:
- Microsoft Visual C++ for Windows, versions 1.0, 1.5, 1.51, 1.52
- Microsoft Visual C++ 32-bit Edition, versions 1.0, 2.0, 2.1, 4.0, 5.0
SUMMARY
The process of developing a dynamic-link library (DLL) with Visual
C++ usually includes debugging. To do so, you must build a debugging
version of the DLL and call it from an application. However, it is not
necessary to build the debugging version of the calling application or to
build the caller with Visual C++.
MORE INFORMATION
The following five steps demonstrate debugging a DLL. Note that it is
not within the scope of this article to provide detailed instructions
for building the DLL.
- Build the DLL with debugging information.
- Specify the fully-qualified path to the calling application. In Visual
C++ for Windows and Visual C++ 32-bit Edition version 1.0, choose Debug
from the Options menu and enter the information under Calling Program.
In Visual C++ 2.x and 5.0, choose Settings from the Project menu; in
Visual C++ 4.0, choose Settings from the Build menu. Select the Debug
tab, and enter the information under Executable For Debug Session.
- Set a breakpoint in the source code of the DLL function to debug.
To do this, place the cursor on the line in the source code to contain
the breakpoint and press F9.
- Choose Restart from the Debug menu. If the calling program does not
contain debugging information, a dialog box appears asking you to
confirm your choice. Choose OK and the program starts execution.
- After you perform the necessary steps to execute the function that
contains the breakpoint, execution stops on the specified line of
code.
