Hi all From this site : http://dotnetperls.com/process-start-net Use the Process.Start method to start external EXEs. This method is in the System.Diagnostics namespace. It will show a console window.  How about if the program running using .dll extension? how to code this? What methods should use? Thanks in advance.

Either your exe will have all the functionalities or you'll have to get another exe (for decryption in your case). YOU CANNOT EXECUTE .DLL FILE. please mark as answerd if helpful.

I think i know what you mean the dll that u referring is the one we created with class library. But just to reconfirm when i download this encyption software it said it have 2 active component one with X.exe and one with Y.dll. when i run X.exe it become decryption. so that mean im lake of one exe that is for encrypt. When i check is registry i assume that this Y.dll is used to encrypt. but I'm not sure. So this Y.dll is a library or execution file? thanks

hi a file with .dll extension is also an assembly (unit of deployment) but you can't run it directly by using any command. It is basically a library which can be referenced in another assembly (.exe). In short you can reference a dll in your project and use its types and methods in your source code.
