How to make a Advance Injector

Post by CFdanz on Sun Jul 31, 2011 3:50 pm

What we gonna do?
We are going to do an Advanced Injector.

What Items we will have?
5 Buttons.
1 Label.
1 TextBox.
1 ListBox.
1 Timer.
1 OpenFileDialog.
So do 5 Buttons.
Name Button1 "Clear Selected"
Name Button2 "Clear Process"
Name Button3 "Clear List"
Name Button4 "Browse"
Name Button5 "Inject"

Do a Label.

Do a TextBox.

Do a ListBox and name ListBox1 to "Dlls"

Do a OpenFileDialog and go to Properties and MultiSelect do it True.

Add a Timer.

Click on Form1 and delete the words and copy and paste this:

NOTE:
This may have some errors because I didn't fully checked it and I need to edit the thread to make it more easy to do.
