In this article, we use the keyboard shortcuts, because it's a good way to get fast at executing your app in the debugger equivalent commands such as menu commands are shown in parentheses. In the code editor, scroll down and hover over the Console. The tooltip for the button shows "Run execution to here". The Run to Click button is new in Visual Studio If you don't see the green arrow button, use F11 in this example instead to advance the debugger to the right place. Click the Run to Click button.
Using this button is similar to setting a temporary breakpoint. Run to Click is handy for getting around quickly within a visible region of app code you can click in any open file. When you press Restart , it saves time versus stopping the app and restarting the debugger.
The debugger pauses at the first breakpoint that is hit by executing code. Features that allow you to inspect variables are one of the most useful features of the debugger, and there are different ways to do it. Often, when you try to debug an issue, you are attempting to find out whether variables are storing the values that you expect them to have at a particular time.
The value of the variable changes with each iteration of the For loop, showing values of f , then fr , then fre , and so on. 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.
In the Autos window, you see variables and their current value. The Autos window shows all variables used on the current line or the preceding line Check documentation for language-specific behavior. Next, look at the Locals window, in a tab next to the Autos window.
The Locals window shows you the variables that are in the current scope , that is, the current execution context. In the main code editor window, right-click the name variable and choose Add Watch.
The Watch window opens at the bottom of the code editor. You can use a Watch window to specify a variable or an expression that you want to keep an eye on. Now, you have a watch set on the name variable, and you can see its value change as you move through the debugger. Unlike the other variable windows, the Watch window always shows the variables that you are watching they're grayed out when out of scope.
While paused in the For loop, click the Call Stack window, which is by default open in the lower right pane. Click F11 a few times until you see the debugger pause in the SendMessage method. Look at the Call Stack window. The Call Stack window shows the order in which methods and functions are getting called. The top line shows the current function the SendMessage method in this app. The second line shows that SendMessage was called from the Main method, and so on.
You can double-click a line of code to go look at that source code and that also changes the current scope being inspected by the debugger. This action does not advance the debugger. You can also use right-click menus from the Call Stack window to do other things. For example, you can insert breakpoints into specified functions, advance the debugger using Run to Cursor , and go examine source code. For more information, see How to: Examine the Call Stack.
While paused in the For loop, click the Call Stack window, which is open by default in the lower right pane. With the debugger paused in the SendMessage method call, use the mouse to grab the yellow arrow the execution pointer on the left and move it up one line, back to Console. The debugger reruns the Console. WriteLine method you see this in the console window output.
Assert statement number. The dialog box also includes three command buttons:. You can also direct output from the Debug class to destinations other than the Output window.
The Debug class has a collection named Listeners that includes Listener objects. Each Listener object monitors Debug output and directs the output to a specified target.
Each Listener in the Listeners collection receives any output that the Debug class generates. You can specify the target for a TextWriterTraceListener class through its constructor. Some possible output targets include:. Listeners collection to receive Debug output. Use Visual Basic. A public module named Module1 is added to the project by default. To initialize variables to contain information about a product, add the following Dim statements:.
Specify the message that the class produces as the first input parameter of the WriteLine method. For readability, use the Indent method to indent subsequent messages in the Output window:. You can also use the WriteLine method to display the namespace and the class name for an existent object.
For example, the following code displays the System. You may need to use the wizard for configuration if you want to run the remote debugger as a service. For more information, see Optional Configure the remote debugger as a service. In some scenarios, it can be most efficient to run the remote debugger from a file share. For more information, see Run the remote debugger from a file share.
On the remote computer, find and start the Remote Debugger from the Start menu. If you don't have administrative permissions on the remote computer, right-click the Remote Debugger app and select Run as administrator. Otherwise, just start it normally. If you are planning to attach to a process which is running as an administrator, or is running under a different user account such as IIS , right-click the Remote Debugger app and select Run as administrator.
For more information, see Run the remote debugger as an administrator. The first time you start the remote debugger or before you have configured it , the Remote Debugging Configuration dialog box appears. Select at least one network type you want to use the remote tools on. If the computers are connected through a domain, you must choose the first item. If the computers are connected through a workgroup or homegroup, choose the second or third item as appropriate. Select Configure remote debugging to configure the firewall and start the remote debugger.
The remote debugger is now waiting for a connection. Use the server name and port number shown to set the remote connection configuration in Visual Studio. You can restart it from the Start menu, or from the command line:. If you need to add permissions for additional users, change the authentication mode, or port number for the remote debugger, see Configure the remote debugger.
Visual Studio will follow the same process to try to obtain symbols as it does when debugging a normal project.
More information and best practices for symbols can be found in this blog. That behavior can be overridden from the Breakpoint Settings peek window. In the settings peek window click on the Must match source link text and then check the box to allow mismatched source, as illustrated below.
This is a really good reason to use SourceLink with your projects. Even if you have a local enlistment you might not have the same version that was used to build the binary. SourceLink is your sure-fire way to make sure that the right source is linked with the right binary.
From the launch page of the profiling tools you can select what tools to use against the EXE. Comments are closed.
A perfectly good article blighted by a clickbait title. Thank you for the feedback. However, when I need to debug any live. Have you heard of dnSpy?
