Loop through folder to unregister ActiveX controls

[strager]

Hi,

I have an app that doesn't uninstall activex controls in a folder.
In my setup, I need to check if that folder exists and if it does, I need to unregister every ActiveX control in that folder.
Then I need to delete the folder and it's contents.
I found how to check for a folder and your sample on unregister activex controls. I just can't figure out how to loop through all the controls when I don't know how many there are.


bresult = Folder.DoesExist("%CommonFilesFolder%\SMS");

if bresult then
Loop through folder and unregister all activex controls in folder
When all controls have been unregistered...
Delete folder and contents.

end

Thanks for your help,

Sheri

I have tried to put something together... Is this correct?

bresult = Folder.DoesExist(SessionVar.Expand("%CommonFilesFo lder%\SMS"));

if bresult then
-- A while loop

while File.Find(SessionVar.Expand("%CommonFilesFolder%\S MS"), "*.ocx", false, false, nil, nil) do
-- Do something here\
sPath =SessionVar.Expand("%CommonFilesFolder%\SMS")
sFolder = String.SplitPath("sPath");
sFile = sFolder.Filename;
sExt = sFolder.Extension;
-- get and set name of control

tFind = File.Find("C:\\", "sName", true, false, nil);
iCount = tFind.Count
-- check to see if another instance of the file exists. If it does, don't unregister or delete.
if iCount <= 1 then
System.UnregisterActiveX("sPath" .. "\\sName");
File.Delete("sFolder".."\\sName", false, false, false, nil);
end


end

Folder.Delete(SessionVar.Expand("%CommonFilesFolde r%\SMS"));


end

Thanks

I have a customer that has installed an application of mine and one of the packages installs an activex that causes an out of memory error.
I couldn't figure out what control is causing the problem but it is one that is in a specific folder.
I unregistered and deleted all controls in a test machine and then installed again with a new setup and I no longer get the error.
What I need to do, is create a setup that will unregister and delete all the controls in that folder, so I can do a fresh install.

Please help... it is urgent! Thank you

Hello,

this should be all you need.

-- check if folder exists
if Folder.DoesExist(SessionVar.Expand("%CommonFilesFolder%\\SMS")) then
    -- find all OCX in folder and retrieve them in a table
    tFiles = File.Find(SessionVar.Expand("%CommonFilesFolder%\\SMS"), "*.ocx");
    -- process each element in the table
    for i, file in tFiles do
        -- unregister
        SetupData.WriteToLogFile("Info\tUnregistering ".. file .. "\r\n", true);
        System.UnregisterActiveX(file);
        -- delete
        SetupData.WriteToLogFile("Info\tDeleting ".. file .. "\r\n", true);
        File.Delete(file);
    end
    -- cleanup
    Folder.DeleteTree(SessionVar.Expand("%CommonFilesFolder%\\SMS"));
else
    SetupData.WriteToLogFile("Info\t" .. SessionVar.Expand("%CommonFilesFolder%\\SMS") .. " does not exist\r\n", true);
end
