AnswerThe answer is, you can't*. A DLL is file created by the compiler after compiling or packaging the source code and there is no way to find out how it is written once it is compiled. If you really trust the source of your DLL, you can add this DLL to a com+ application and find out the methods and functions available through the DLL, and the parameters for those. Alternatively, you can create a simple ASP file and create an instance of this DLL and find out all the methods and functions that way too. AdditionYou can open them with notepad, but you won't be able to understand anything as it's all in computer code.

*unless it was developed in (at least as I know of) MS Visual Studio .NET, then you may examine the functionalities thereof by means of your object browser and the functionalities, properties, methods, etc are exposed there. The extent to which these functionalities are understood is directly related to how well the programmer of this (D)ynamic (L)ink (L)ibrary documented it. In other words, this is in its functional form, no further compilation is required, but it may as well adhere to the conformaty set forth by Microsoft via Visual Studio .NET an IDE (Integrated Development Environment) whereby you may examine its programming resources.

How do you open .dll files to see what is written inside?

A DLL is a library file that contains functions for other programs to use. In order for these functions to be run their code must have been compiled. Compiling is the process of taking source code in a language like C++ or Visual Basic which can be read by humans, and converting it into machine code that can be read by a computer processor. As such it is very hard to 'read' DLL files as the actual functional code is machine code. In order to read the source code you would have to attempt to reverse-engineer the machine code. Reverse compilation is touchy legal area which is usually very hard as the machine code may have been written in any high-level language, you would have to find out which one it was written in to have good shot of decompiling it. It would also likely be encoded. You can use a program such as "DLL Export Viewer" (see Related link below) to 'view' DLL files.
