10. Why I use MsgBox in the ASP program, the program error said no permissions
A: Because the ASP is the server running, if you can display a dialog box on the server, then you have to wait for someone to confirm, your program can continue to execute, and the general server will not be guarded, so Microsoft had to ban this function, and told you in random (:) OH) No permissions. However, ASP and client-side scripting can be combined to display a dialog box, as follows:
<% yourvar= "Test dialog box"% >
<% script language= ' JavaScript ' >
Alert ("<%=yourvar% >")
</script >
11. There is no way to protect their source code, do not give people to see
A: You can download a Microsoft Windows Script Encoder, which can encrypt the ASP scripts and client Javascript/vbscript scripts ...

DLL EXTENSION input HTM method exclusions input put.delete all OK. However, it should be noted that the HTM is also handled by Asp.dll, and the efficiency will be reduced.
15. How to register components
Answer: There are two ways.
The first method: Manually registering DLLs This method is used from IIS 3.0 to IIS 4.0 and other Web servers. It requires you to run down the command line, into the directory containing the DLL, and enter: regsvr32 component_name.dll for example C:\temp\regsvr32 AspEmail.dll It registers specific information about the DLL into the registry in the server. This component can then be used on the server, but there is a flaw in this approach. When the component is registered with this method, the component must be set to the appropriate NT anonymous account to execute the DLL. In particular, some components need to read the registry, so the method of registering the component is simply using the server without MTS, to unregister the DLL, using: regsvr32/u Aspobject.dll Example c:\temp\regsvr32/u Aneiodbc.dll
The second approach: using MTS (Microsoft Transaction Server) MTS is a new feature of IIS 4, but it provides a great deal of improvement. MTS allows you to specify that only privileged users have access to the component, greatly improving the security settings on the Web server. The steps for registering a component on MTS are as follows:
1 Open the IIS Management Console.
2) Expand Transaction Server, right-click "pkgs Installed" and select "Ne
