[WiX-users] Referencing a command from a Rollback & Uninstall custom action to avoid duplication

[Kiran Challa]

Hi,

This question is from a maintenance perspective where currently I am 
duplicating the same command in a Rollback custom action and a Uninstall custom 
action.

If you notice from the following example, I am duplicating the command for the 
rollback action "SetBtsAddAppRollback" in the uninstall action "SetBtsRmvApp" 
also.

I would like to avoid this duplication...Can you please suggest how could I 
make these 2 custom actions reference a single declaration of a command (I 
mean, let's say you declare this command somewhere and both these custom 
actions reference it)?


Example:

<CustomAction Id="SetBtsAddAppRollback" Property="RunBtsAddAppRollback" 
Execute="immediate" Value="&quot;[BTS09TSK]&quot; removeApp 
/applicationName:&quot;!(loc.BiztalkApplicationName)&quot;" />
<CustomAction Id="RunBtsAddAppRollback" BinaryKey="WixCA" 
DllEntry="CAQuietExec" Execute="rollback" Return="ignore" />

  <CustomAction Id="SetBtsAddApp" Property="RunBtsAddApp" 
Value="&quot;[BTS09TSK]&quot; addApp 
/applicationName:&quot;!(loc.BiztalkApplicationName)&quot; 
/description:&quot;!(loc.BiztalkApplicationName)&quot;" />
  <CustomAction Id="RunBtsAddApp" BinaryKey="WixCA" DllEntry="CAQuietExec" 
Execute="deferred" Return="check" />


  <CustomAction Id="SetBtsRmvApp" Property="RunBtsRmvApp" 
Value="&quot;[BTS09TSK]&quot; removeApp 
/applicationName:&quot;!(loc.BiztalkApplicationName)&quot;" />
  <CustomAction Id="RunBtsRmvApp" BinaryKey="WixCA" DllEntry="CAQuietExec" 
Execute="deferred" Return="ignore" />


Thanks,
