Use this dialog box to select existing projects and add them to your solution. You can add an existing project from local or network directories and Web sites. Access the Add Existing Project dialog box by selecting Add Project on the File menu. A solution must be open in order to access this dialog box.
Before opening an existing project or component, determine the trustworthiness of the code outside of the Visual Studio designer. Opening projects or components in the Visual Studio designer automatically executes code from that project or component on your local machine in the trusted process of devenv.exe.
Before adding an existing project from shared directories in a multi-developer environment, you should attempt to ensure that your changes do not adversely affect or overwrite another developer's changes.
Use this drop-down list box to select an existing project by exploring a hierarchically structured view of files, folders, local drives, mapped network drives, and pointers to other Web resources on your computer.
You can use the Look in drop-down list box to add, modify, or remove an FTP location.
Use this text box to filter files and folders by name. Type the full or partial file name on which to filter, using an asterisk (*) as the wildcard character. Filtering allows you to locate a file or folder whose full name or exact location is unknown.
Navigate to Web and network locations by entering the URL or network path in the File name box. For example, "http://mywebsite" displays the files available at the "mywebsite" Web location and "\\myserver\myshare" displays the files available at the "myshare" location on "myserver."
If you try to access and build Visual C++ projects directly over a network, you will experience problems. Visual C++ does not perform any special operations to accommodate network drives and shares, and it is unaware of whether the file it is reading or writing is on a network drive or a local drive. Use of Visual C++ in this manner is not supported. For more information, see Microsoft Knowledge Base article 255252.
Files of type
Use this text box to filter project files by file extension. This drop-down list box contains all project file types for installed Visual Studio components. Filtering by file type is especially useful when searching for a project item whose exact name is not known.
