Hi, WolfPack, Sorry to disturb, May I ask?

I was confused with the dll. I just want to call the third-party software.exe to help me do the compression and decompression part. Do I need to call the dll? Or, Can I just call the .exe from my software?

Sorry for causing any confusion, I was not clear with dll before I put this thread, after I read the pdf about dll, I think that maybe I dont need to call dll but just call the exe.

Please forgive me, I apologized for the trouble caused by me.

Do you think it is possible to call any CODEC software exe from my software? Which one is easier for a newbie like me?

But, I dont know how can I do so, do you mind to give me some guidance? Please, Please forgive me for my ignorance. I try my best in doing it. Hope you can teach me some. Please.
