[Visual Basic]Multiple Injector

This is an OPEN SOURCE injector.

What it does:

- Multiple .dll injection
- Only inject selected .dll
- Clear listbox
- Remove selected item from listbox
- Timer checking for process
- Save listbox content
- Load listbox content
- Close after injection
- Checkbox/textbox settings save
- Only adds items to the listbox if they are not duplicated/do not contain "OpenFileDialog1"
- error handling
- commented code


What you should add:

- Multiple selection when selecting .dlls =D Can't be bothered to do that nao



"to select add" for sure is meant to be "to add".

Sorry I cannot upload any further virusscan, those sites are rarely working for me -.-


Enjoy.

Omg, Not another 1 .

You should join me in making an .DLL injector tut (that is good) so people stop asking questions about them .
and urs looks kinda nice.
