Subject: Re: [NAnt-users] MSI Task: Remove all files/folder during uninstall
Hi Tom,
There are two ways to do this. One is to use the RemoveFile table, and the other is to use a custom action. The RemoveFile table is probably simpler as it links to the conponents you are installing, but unfortunately it's not directly supported by the <msi> task so you have to use the <tables> element to define it. Try something like:
<tables>
<table name="RemoveFile">
<columns>
<column name="FileKey" nullable="false" category="Identifier" key="true" description="Primary key used to identify this particular table entry." />
<column name="Component_" nullable="false" category="Identifier" description="External key the first column of the Component table. This field references the component that controls the file to be removed." />
<column name="FileName" nullable="true" category="WildCardFilename" description="This column contains the localizable name of the file to be removed. If this column is null, then the specified folder will be removed if it is empty. All of the files that match the wildcard will be removed from the specified directory." />
<column name="DirProperty" nullable="false" category="Identifier" description="Name of a property whose value is assumed to resolve to the full path to the folder of the file to be removed. The property can be the name of a directory in the Directory table, a property set by the AppSearch table, or any other property that represents a full path." />
<column name="InstallMode" nullable="false" category="Integer" description="1=Remove only when the associated component is being installed, 2=Remove only when the associated component is being removed, 3=Remove in either case." />
</columns>
<rows>
<row>
<columns>
<column name="FileKey" value="R_MyFiles" />
<column name="Component_" value="C_MY_COMPONENT" />
<column name="FileName" value="*.*" />
<column name="DirProperty" value="D_MY_DIR" />
<column name="InstallMode" value="2" />
</columns>
</row>
</rows>
</table>
</tables>
You can add as many <row> elements in the <rows> element as you wish to define the files and directories to be removed. see http://msdn.microsoft.com/library/default.asp?url="" fopr more detail on the column values. I haven't tried this myself, so you may have to play about with it a bit and run your script through msiexec with debug on to get it working.
If you really do need to take the Custom Action approach, then you could write a simple _vbscript_ function to delete the files and folders and add it to your <binaries> table. Create a custom action of type 6 to execute the script. Within the script, you will have a Session object provided by the installer, and you can get hold of the properties in the installer via the ProductProperty(string) property on this object. That should presumably allow you to get hold of the folders/files you need to delete.
HTH,
Bill

Hi,I want to add a custom action, which removes all files and folder of my installation during uninstall. Is there a way to add such a custom action inside the msi task? An example would be great!
Thanks,
