. NET is a language that is built on a virtual machine that generates the intermediate language of the MSIL directly, and then the. NET compiler JIT interprets the image as native code and delivers CPU execution. The intermediate language is easy to decompile, so study how to effectively protect DLL files. My approximate method is: Strong signature + obfuscation + encryption. Strong-Signed strong-named assemblies ensure that your assemblies are unique
We know that Windows DLL is not able to run independently, but Microsoft provides rundll32.exe for running DLLs.
First Test: Run "Rundll32.exe Shell32.dll,restartdialog", will pop up the restart dialog box. This same way you can turn on other features of the Windows system.
Here's how to define your own DLL to let Rundll32.exe run.

Msvcr100.dll is a dynamic link library of Visual Studio 2010, if a program is developed with it, then the program may need to run the dynamic link library, some programs directly packaged it into the installation directory, and register, there will be no missing problems; However, some programs have the default system in the dynamic link library, no processing, there will be missing problems. So what is the reason for the loss of Msvcr100.

This article is a VB-generated DLL that encapsulates ASP code to connect to a database (for example, in an Access database).
In general, when we use ASP to connect to an Access database, we typically do the following:
'//proconn.asp
Dim proconn
Set Proconn=server.createobject ("ADODB. CONNECTION ")
Proconn.open "Driver={microsoft Access driver (*.mdb)};uid=;p wd=123;dbq=" Server.MapPath ("db.asp")

Now three-tier development, with ASP and VB6.0, but now suffer from not finding the right way to debug their own written DLL file, the efficiency is very low.
I have used several methods:
1. Select Uninstall in IIS, then recompile with VB, overwriting the original DLL
2. Select a site in IIS you are debugging, stop, and then compile the overlay, then start, and then refresh the page in IE.
3. Execute regsvr
