Deleting the existting IIS Virtual Directory

[thurein]

Hi.

Is there any ways that the MSI can delete the IIS Virtual Diectory (or web application) under the Default Web Site, before installing a feature.

Thanks

Hi,
I don't know of a way to do it through installshield.
I used a custom action.

function DeleteVirtualDir(hMSI, szDeleteVR)
OBJECT objIIS_Root, objIIS_Sub;
begin

set objIIS_Root = CoGetObject("IIS://localhost/W3SVC/1/Root", "");
set objIIS_Sub = CoGetObject("IIS://localhost/W3SVC/1/Root/" + szDeleteVR, "");

if (IsObject(objIIS_Sub)) then
objIIS_Root.Delete("IISWebVirtualDir", szDeleteVR);
SprintfMsiLog ( "DeleteVirtualDir deleted virtual directory: %s" , szDeleteVR);
else
SprintfMsiLog ( "DeleteVirtualDir could not delete virtual directory: %s" , szDeleteVR);
endif;

end;


hope this helps.

I was trying to get the IIS object by using the following code almost the same logic as urs

set objIIS_Root = CoGetObject("IIS://localhost/W3SVC/1/Root", "");
if (IsObject(objIIS_Root)) then
\\do delete
but the objIIS_Root object got empty all the time so it won't pass the if statement and the delete logic will not be executed. I have tested the above code in both IIS 6 and 7. Pls advice what I am doing wrong.

Thanks Thurein

What part of the ROOT are you deleting?
Post your full code example.

[thurein]

following is my code. When I check the MSI log, it said "could not delete virtual directory" which means it is only going through the else statement. In my IIS, I have a "Default Web Site" and under that I created a Application called "MyVitualDir".

function MyFunction(hMSI)

OBJECT objIIS_Root, objIIS_Sub;
begin

set objIIS_Root = CoGetObject("IIS://localhost/W3SVC/1/Root", "");
set objIIS_Sub = CoGetObject("IIS://localhost/W3SVC/1/Root/MyVitualDir" , "");

if (IsObject(objIIS_Sub)) then
objIIS_Root.Delete("IISWebVirtualDir", "MyVitualDir");
SprintfMsiLog ( "DeleteVirtualDir deleted virtual directory: %s" , "MyVitualDir");
else
SprintfMsiLog ( "DeleteVirtualDir could not delete virtual directory: %s" , "MyVitualDir");
endif;

end;

Thanks

Hi,

Is the action you have created, deferred in system context?

On operating systems with UAC.
It needs to be deferred in system context to remove the iis. So you might aswell try this before the IIS website are created again in the execute part of the msi installation.

Hi,
I have set the "In-Script Execution" to "Deffered Execution in System Context" and "Install Exec Sequence" to "After InstallInitialize" but it is still going through the else statement. Any idea ?

Thanks

Are you running it in the execute part of the installation and not from a button click?

[thurein]

I just double clicked on the setup.exe.

Thanks

Yes, you need to run the installation using the setup.exe, but where/how are you running the custom action to delete the virtual directory?
