In the Autos window, you see variables and their current value. If it is closed, open it while paused in the debugger by choosing Debug > Windows > Autos. Look at the Autos window at the bottom of the code editor.

Inspect variables with the Autos and Locals windows Often, when debugging, you want a quick way to check property values on variables, to see whether they are storing the values that you expect them to store, and the data tips are a good way to do it. The value of the variable changes with each iteration of the for loop, showing values of f, then fr, then fre, and so on. Press F5 (or Debug > Continue) a few times to iterate several times through the for loop, pausing again at the breakpoint, and hovering over the name variable each time to check its value.

Next, hover over the name variable, and you see its current value, an empty string. Įxpand the letters variable to see its properties, which include all the elements that the variable contains. Void SendMessage(const std::wstring& name, int msg) In get-started-debugging.cpp, replace all of the default code with the following code instead: #include In the Configure your new project window, type or enter get-started-debugging in the Project name box. Then, in the Visual Studio Installer, choose the Desktop development with C++ workload. In the Not finding what you're looking for? message, choose the Install more tools and features link. If you do not see the Console App template, you can install it from the Create a new project window.

F# and JavaScript do not support the Autos window). If this is the first time that you've tried to debug code, you may want to read Debugging for absolute beginners before going through this article.Īlthough the demo app is C++, most of the features are applicable to C#, Visual Basic, F#, Python, JavaScript, and other languages supported by Visual Studio (F# does not support Edit-and-continue. You can step through your code and look at the values stored in variables, you can set watches on variables to see when values change, you can examine the execution path of your code, see whether a branch of code is running, and so on. When you do this, the debugger provides many ways to see what your code is doing while it runs. When you debug your app, it usually means that you are running your application with the debugger attached. If you want a higher-level view of the debugger features, see First look at the debugger.
