Debugging Libraries in Visual Studio: A Comprehensive Guide


Developers often face the challenge of ensuring code quality and identifying potential issues in their software. Debugging libraries is an important task that aids in these efforts. Visual Studio is a powerful tool that simplifies the debugging process. In this article, we will discuss the step-by-step process of how to debug libraries in Visual Studio.

Step 1 – Create a New C++ Project

To initiate the debugging process, create a new C++ project in Visual Studio. To do so, you need to click on “File” and select “New” followed by “Project.” From the available templates, choose the “Visual C++” option and select the “Dynamic-link Library (DLL)” template.

Step 2 – Configure the Project

After selecting the project template, the next step is to configure the project settings, set the appropriate name, location, and additional parameters. It is crucial to ensure that the “Debug” configuration is selected in the properties of the project.

Step 3 – Write the Code

Now, you need to write the code for the library, adding all the required classes and functions to the project. It is critical to add breakpoints to the code where you think the code is not functioning correctly.

Step 4 – Build the Project

After writing the code, you need to build the project by pressing “F7” or selecting “Build” and then “Build Solution.” This step is necessary to ensure that the project builds without any errors.

Step 5 – Debug the Library

To debug the library, set breakpoints at lines where you suspect there may be issues. After setting the breakpoints, run the project in debug mode by pressing “F5” or selecting “Debug” and then “Start Debugging.”

Step 6 – Use the Locals and Watch Windows

The Locals and Watch windows are useful in viewing the values of variables and objects at runtime, and these windows help identify issues in your code. You can open the Locals window by selecting “Debug” followed by “Windows” and then “Locals.” Similarly, to open the Watch window, click on “Debug” > “Windows” > “Watch.”

Step 7 – Use the Call Stack Window

The Call Stack window is another tool that shows the sequence of function calls that lead to the current execution point. It helps in identifying which function caused the issue. To open the Call Stack window, click on “Debug” > “Windows” > “Call Stack.”

Step 8 – Use the Output Window

The Output window displays debugging information such as output from printf statements, flow control messages, and other logs. It can be accessed by clicking on “Debug” > “Windows” > “Output.”

Step 9 – Fix the Issue

After identifying the issue using the debugging tools in Visual Studio, make the necessary code modifications to fix the issue.

Step 10 – Test and Repeat

After the code modifications are made, rebuild the project and test again to ensure that the issue has been fixed. If there are still issues, repeat the debugging process until the problem is resolved.
