I just want to know how I can change asm instructions in the IDA-view A:

  1. How to edit instructions(for instance: jnz to jmp)?
  2. How to insert new instructions(call func1, call func2 inserted to existing code)?

I know how to make dif files, I know how to apply the changes on my DLL, but how can I "make the difference"? How can I edit the code in IDA?

I learned how to modify a DLL:

  1. Modify code(how?)
  2. Generate dif file.
  3. Apply the code modifications to the DLL with the dif file and a script.

Use Edit->patch program->assemble to write in assembly syntax

Use Edit->patch program -> patch bytes to edit bytes in the binary

Finally, use Edit->patch program -> apply patch to input file to apply patches. I'v personally used it in IDA 7.0

Try IDA Pro 6.1 or 6.2. It has the ability to write the changes to the input file directly.
