Hi,

can somebody explain me the advantage of registering a dll as shared dll ?
Is the dll loaded only once into the memory ?

My application (several vds exe files) needs much ram - i think because of the many dlls I use in each exe.

Thanks for your help

Bye, Fabian

Hi Codescript,

thanks for your answer.
Several installers (for example innosetup) have the option for registering a dll as shared dll (in the registry). So you say there is no difference for working with a vds dll in my directory and a vds dll registered as shared dll ?

Bye, Fabian

I don't know what the setup does ?
I think shared means it is placing the dll in system directory.
IMHO placing the dll in your app directory/subdirectory is far better to avoid the "dll hell" (dll version conflict problems)

I think the option for registering shared DLLs is purely to do with uninstalling. If you register it as a shared DLL, Windows keeps a count of the number of applications that used it, and if the count decrements to zero, the installer can offer you the option of removing it.
