Some of the previously collected data---use component technology to protect your ASP code

Use components to protect your ASP code
Before we talked a lot about the security of Open database connection, now I put forward a kind of thinking
Use an ActiveX DLL to protect your code. (You don't have to worry about using shared encryption software,
More importantly, you can top the encryption method, enjoy the "everything in control" feeling.
At the same time, in order for everyone to do their own work to make their own components. ）
ActiveX DLLs is a compiled machine code that cannot be compiled without the source project file.
This technology makes it possible for developers to develop public automation programs and publish them as shareware versions of programs
This technology can be seen in some of the components that you sell in chinaasp.
If you want to protect the security of some code in your ASP, for example you don't want others to see what you are using to connect to
database, or do not want to let others see how some of your more important functions are done, or some important
Process (Cakk can refer to), you can continue to develop your own components, this is a DLL file, that is, others get
This DLL file, 1:30 will also not be able to get the important information you want to protect. And the components that you developed yourself
brings a stream of new features to your program.
Here's a very common example of how to open a database in a confidential way.
The simple example is to display the contents of a field in a database in a Drop-down box.
The whole process is as follows:
1. Create a new VB6 ActiveX DLL project
2. In the Properties window, name your library module and project file. Example is the Keiths_lookup project name and the lookup module name.
This name is the name of the DLL function you refer to in ASP (the object name in ASP is Keiths_lookup.lookup).
3. Save the Project and library module with the same name (of course, the suffix is not able to be the same OH).
4. Select References from the Project menu in VB6. Then select the Microsoft ActiveX Data Objects 2.0 library, Microsoft
ActiveX Data Objects Recordset 2.0 library.
The code for the file is as follows:
Public Function Html_combo (ComboName As String, Lookup_field as String) as String
Dim outstring as String
Dim Conn as ADODB. Connection
