爱华网While there are predefined session variables available to use, you can also create custom session variables at design time and run time. At design time, they can be defined on the Session Variables tab of the Project Settings dialog. At run time, you can create and manipulate session variables using the available SessionVar actions.
Note: If a session variable used on a screen needs to be set to a different value, it must be set prior to the screen's displaying, and all of its events. Another option is to set the text of the screen control using the appropriate Dlg***.SetProperties action. Any changes made to a session variable on a screen after the screen has been created (just before the On Preload event) will have no effect.
The following pre-defined session variables are available in Setup Factory:
%AppFolder%
Your application's main directory, where all of your files and folders will be installed. For example, by default Setup Factory's main directory is C:Program FilesSetup Factory 7.0.
%AppFolder% is initially set to the default value that you give it on the Session Variables tab of the Project Settings dialog. However, in most installations, the value of %AppFolder% will ultimately be set by the user on the Select Install Folder screen, overriding the default value.
%ApplicationDataFolder%
The path to the per-user Application Data folder on the user's system. This folder serves as a common repository for application-specific data. Typically, this path is something like "C:Documents and SettingsYourNameApplication Data."
%ApplicationDataFolderCommon%
The path to the all-user Application Data folder on the user's system. This folder servers as a common repository for application-specific data. Typically this is something like "C:Documents and SettingsAll UsersApplication Data."
%AppShortcutFolderName%
The name of the shortcut folder on the Start menu where your application's shortcuts will be stored.
%AppShortcutFolderName% is initially set to the default value that you give it on the Session Variables tab of the Project Settings dialog. However, in many installations, the value of %AppShortcutFolderName% will ultimately be set by the user on the Select Shortcut Folder screen, overriding the default value %ProductName%.
%AppDrive%
The drive letter of %AppFolder%. You should not set this variable explicitly. It is reset every time that %AppFolder% is re-assigned. For example, if %AppFolder% is C:Program FilesMy Program, %AppDrive% will be C:.
%CommonFilesFolder%
The user's Common Files folder. Typically, this is something like: C:Program FilesCommon Files.
%CompanyName%
Your company’s name. The value of this variable is set on the Session Variables tab of the Project Settings dialog.

Your company’s URL. The value of this variable is set on the Session Variables tab of the Project Settings dialog.

The path to the user’s font directory (e.g. "C:WindowsFonts").
%MyDocumentsFolder%
The user's personal (My Documents) folder on their system. Usually this is something like "C:Documents and SettingsYourNameMy Documents" on Windows 2000/XP and "C:My Documents" on Windows 98/ME.
Note: Windows 95 did not have the My Documents folder and this variable will return "C:" if run on such a system.
%ProductName%
The name of the product that you are installing. The value of this variable is set on the Session Variables tab of the Project Settings dialog.
%ProductVer%
The version number of the product that you are installing. The value of this variable is set on the Session Variables tab of the Project Settings dialog.

The full path, including the filename, for the current setup executable.
For example, if the user was running "setup.exe" from "C:Downloads", %SourceFilename% would be expanded to "C:DownloadsSetup.exe".

The path to the user's Start menu folder. On Windows NT/2000/XP, this is the path from the per-user profile.

%StartupFolder%

Usually this directory will be the user's temporary directory, unless the user overrides the temporary directory with the /T command line option.
