WiseScript Editor Reference
To complete the dialog box
If System
Use the drop-down lists to build a statement of what to check for.
Note
When you check for an operating system, this action looks for the minimum
operating system of the type for which you're checking. Example: If you check for
Windows XP, this action returns TRUE if Windows XP or later is running.
Action
Occurs when the statement above is true. All options below display the message
described in Title and Message Text below, unless Message Text is blank.
Display Message Only
Abort Installation
Start Block
Begins a conditional block. All actions between this action and the next Else or
End action are executed.
Title
Enter the title for the dialog box.
Message Text
Appears in the body of the message dialog box. Leave this blank to prevent a
message from appearing.
Note
Checking for "Share Loaded" opens a temporary file and tries to lock a section of it.
It detects all versions of DOS SHARE, Windows VSHARE, Windows NT/2000/XP/
2003/Vista/2008/7, and Windows 95/98. Checking for "VGA or better" graphics
ensures that display resolution is at least 640x480. Checking for free memory tests
the amount of memory (including virtual memory) available at installation time.
The sample script CheckVGA.wse uses this action. For details on sample scripts, see
ScriptHelp.htm in the Samples subdirectory of this product's installation directory.
This action determines if enough disk space is available for the installation, based on
files that are always installed. You would use this action only if the WiseScript contains
Install File(s) actions that install files permanently on the destination computer.
Note
When a WiseScript is used in a Windows Installer installation, an alternative to using the
Check Disk Space action is to determine how much disk space the WiseScript .EXE
requires, and putting that figure in the ReserveCost table in the Windows Installer
database. This works best when all files are always installed. See ReserveCost Table in
the Windows Installer SDK Help.
You can leave all fields blank and the action checks disk space for all files. This action
takes the cluster size of the disk into account.
