![]() Open all downloaded snippet files in Notepad or the XML editor of Visual Studio and review them carefully before installing them. Snippets downloaded from the Internet should be treated like any other downloaded content - with extreme caution.ĭownload snippets only from sites you trust, and use up-to-date virus software. However, they can create security risks in your application. IntelliSense code snippets installed by Visual Studio are not in themselves a security hazard. Protecting resources (such as event logs, registry)įor more information, see Securing applications. The following list contains a few of the areas that must be considered. How secure a snippet is depends on where it is used in the source code and how it is modified once it is in the code. In addition, the user may not have permissions to write to the file. Be aware that between the time the user selects a file and the time your code manipulates the file, the file may be deleted. You can use the OpenFileDialog and SaveFileDialog controls to reduce the likelihood of invalid file names. For individual user data, the application can create a file for each user in the Documents folder. For application data, we recommend the Application Data folder. Storing files in the root folder ( C:\) is not secure. Users may not have access to the Program Files folder of the computer, so storing files with the application files may not work.įinding a secure location. When you adapt file locations to your application, you should think about the following:įinding an accessible location. For examples, see How to: Handle an exception using try/catch (C#) and statement (Visual Basic). For each exception, there are several ways to respond. That may not be the right choice for your project. Typically, code snippet Try.Catch blocks catch and rethrow all exceptions. For most applications, the code must be modified to suit the application. The code in a code snippet shows only the most basic way to do something. Applies to: Visual Studio Visual Studio for Mac Visual Studio Code
