How to Cast $SKIP_UNINSTALL$ InstallAnywhere Variable To String Or Boolean Data Type

[#1]

Summary

This article discusses how to cast the $SKIP_UNINSTALL$ InstallAnywhere variable to a string or boolean data type for use in Custom Code.

Synopsis

This article discusses how to cast the $SKIP_UNINSTALL$ InstallAnywhere variable to a string or boolean data type for use in Custom Code.

The $SKIP_UNINSTALL$ InstallAnywhere variable determines whether the uninstaller will run actions in the Uninstall Sequence (for more information, see below in the Discussion section).

Discussion

Here is more information about the $SKIP_UNINSTALL$ variable:

Tells the uninstaller whether to perform the uninstall step. To cause the uninstaller to skip the uninstall step, set $SKIP_UNINSTALL$ to true. To allow the uninstall step to occur, set $SKIP_UNINSTALL$ to false. ($SKIP_UNINSTALL$ is false by default.) If the installer skips the uninstall step, it sets $UNINSTALL_SUCCESS$ to SKIPPED.

Note: The Uninstall Complete panel tests the value of $UNINSTALL_SUCCESS$ variable and provides controls for you to customize the message the panel shows in the event that the uninstall step was intentionally skipped.

As for casting the variable to a different data type, namely to a string or boolean, here is sample custom code for a custom code action:

package com.zerog.ia.cca;

import javax.swing.JOptionPane;

import com.zerog.ia.api.pub.CustomCodeAction;
import com.zerog.ia.api.pub.InstallException;
import com.zerog.ia.api.pub.InstallerProxy;
import com.zerog.ia.api.pub.UninstallerProxy;

public class SkipUninstallTest extends CustomCodeAction
{
@Override
public void install(InstallerProxy ip) throws InstallException
{
// TODO Auto-generated method stub
}
@Override
public void uninstall(UninstallerProxy up) throws InstallException
{
String sSkipUninstall = up.substitute("$SKIP_UNINSTALL$");

boolean bSkipUninstall = false;

bSkipUninstall = Boolean.valueOf(sSkipUninstall);

if(bSkipUninstall==true)
{
JOptionPane.showMessageDialog(null, "$SKIP_UNINSTALL$=" + sSkipUninstall);
}
else if(bSkipUninstall==false)
{
JOptionPane.showMessageDialog(null, "$SKIP_UNINSTALL is false");
}
}

@Override
public String getInstallStatusMessage()
{
// TODO Auto-generated method stub
return null;
}

@Override
public String getUninstallStatusMessage()
{
// TODO Auto-generated method stub
return null;
}
}
