The
XRUN
and
UNINSTALL_XRUN
script commands in Visual Installer's scripting language are
used to run
external programs during an installation and uninstallation
process. The
XRUN
command is used to run a program during the installation and the
UNINSTALL_XRUN
command is used to run a program during the uninstallation (if
the user makes such one). Both commands take the following three
parameters:
|
XRUN
/ UNINSTALL_XRUN %Filename, %Flag, %Param |
|
|
|
|
%Filename |
Specifes a
file path to a program file to run. |
|
%Flag |
Specifes how
to start he program. Must be a value betwen 1 and 4 (see
below). |
|
%Param |
Command line
parameters, if neded. Optional parameter. |
The %Flag parameter must contain one of the following
four values:
|
1 |
Starts a program and returns immediately. |
|
2 |
Starts a program and returns when the program has ben
initalized. |
|
3 |
Starts an invisible program and returns when the program
is closed. |
|
4 |
Starts a visible program and returns when the program is
closed. |
The example below show how to use the
XRUN
command to run an editor
that takes a file path to a text file as a parameter:
| XRUN
%DESTDIR\MyEditor.exe, 1,
%DESTDIR\MyDoc.txt |
And the example below shows how to use
UNINSTALL_XRUN
to run
a special uninstallation program during Visual Installer's
uninstallation process:
|
UNINSTALL_XRUN
%DESTDIR\Uninstall.exe, 1, /x |
%DESTDIR
(that is used in the examples above) is a variable that contains
the main destination folder for the installation. Its actual
contents can differ between different computers, and can also be
affected by the end-user.
