9 How to pass variables from one page to another

You should use the hidden type to pass variables

<% form method= "POST" action= "mynextpage.asp" >

<% for each item in Request.Form%>

<input namee= "<%=item%>" type= "HIDDEN"

Value= "<%=server. HTMLEncode (Request.Form (item))%> ">

<% Next%>

</form>

10 Why I use MsgBox in the ASP program, the program error said no permissions

Answer 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 at 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

You can download a Microsoft Windows Script Encoder, which can encrypt the ASP script and the client Javascript/vbscript script ... However, after the client is encrypted, only IE5 can execute, server-side script encryption, only the server installed script engine 5 (installed a IE5 have) to perform.

12 How can I transfer query string from one ASP file to another?

Global.asa files always don't work?

Global.asa is valid only if the Web directory is set to Web application, and Global.asa is valid under the root directory of a Web application. IIS4 can use Internet Service Manager to set application setting how can I make an HTM file Execute script code just like an ASP file?

14 How can I make an HTM file Execute script code like an ASP file?

Answer Internet sevices Manager-> Select Default Web site-> right mouse button-> Menu Properties-〉 Home directory-> application settings (Application Setting)-> Click button "Configure" -> app mapping-> Click on the button "Add"-> executable browse select \winnt\system32\inetsrv\asp. DLL EXTENSION input HTM method exclusions input put.delete all OK but it is worth noting that the HTM is also handled by Asp.dll, and the efficiency will be reduced

15 How to register components

There are two ways of answering

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 execute it on the command-line, enter 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 on 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: I opens the IIS management Console. II Expand Transaction Server, right-click "pkgs Installed" and select "New Package" III) Click "Create an empty package" IV to name the packet V) specify Administrat or Account or use "interactive" (if the server is often logged in with the administrator) now use the right mouse button to click the "Components" after the package that you just created. Select "New then Component" VI to select "Install new component" [B]VII) to locate your. dll file and select next to complete. To delete this object, simply select its icon, and then select Delete. Note: In particular, note the second method, which is the best way to debug your own writing components, without having to reboot the machine every time.
