ListBox/Injector Help

I am having a go at an injector and ive used a source.
The source was meant to inject only 1 .dll and i want it to inject a set of .dlls in a listbox.

Above code was the original source code, it worked fine.

This code was what i changed, im not sure if its this, but when i run the exe it seems to inject but nothing happens.

Any help available?

Can you PM me that source code??

And I have always had troubles with listboxes, so sorry for no help there.
