When working with Windows applications, it is important to be able to get the exit code of the application from the command line. This exit code can give valuable information about the success or failure of the application, and can help with troubleshooting any issues that may arise.
To get the application exit code from a Windows command line, you can use the "echo %errorlevel%" command. This will display the exit code of the previously executed command or application.
For example, if you run a program called "myapp.exe" and it returns an exit code of 0, this means that the program has completed successfully. However, if the exit code is anything other than 0, it indicates that there was an error or issue with the program.
Another useful command for getting the application exit code is the "errorlevel" command. This command can be used in batch files or scripts to check the exit code and perform different actions based on the result.
For instance, you can use the "if" statement to check if the exit code is 0, and if it is, then perform a certain action. If the exit code is not 0, you can use the "else" statement to perform a different action. This allows for more advanced and automated handling of application exit codes.
It is also important to note that some applications may have specific exit codes for different scenarios. For example, an exit code of 3010 may indicate that the application requires a reboot, while an exit code of 1603 may indicate that the installation failed.
In addition to using the command line, you can also view the exit code of an application through the Task Manager. Simply right-click on the application in the processes tab and select "Go to details." From there, you can view the exit code in the "Status" column.
Knowing the application exit code can be extremely helpful when troubleshooting issues with Windows applications. It can save time and effort by quickly identifying the root cause of the problem.
In some cases, the application may provide a more detailed description of the exit code. For example, if the program runs into an error due to insufficient permissions, the exit code may provide information on the specific access denied error.
In conclusion, getting the application exit code from a Windows command line is a simple and effective way to gather information about the success or failure of an application. Whether you are a developer or a user, understanding and utilizing the exit code can make troubleshooting and problem-solving much easier. So next time you encounter an issue with a Windows application, remember to check the exit code for valuable insights.
