how can I keep a dll resident in memory?

[sfoxover]

Hi,

Is there any way to keep a dll or plug-in resident in memory for the duration of the install. I have an exported function call that I run as soon as the installer loads. I then want to call the dll again after I insert a custom dialog. I have a lot of data persisted in the dll that I do not want to convert into a format that can be persisted in the InstallAware script. Is there any way to keep this dll alive for the entire install session?

Regards

Steve

Other than using hooks (you can look that up) you might try using a singleton COM object built as a dll and you can run it as an executable from the first program, if noone calls a deref on the COM object it will stay in memory, you can just start program 2 before you end program one, etc.
