Check error methods available with the IIS debugger

When debugging an ASP program with IIS, some pages can display error lines and causes of errors, although the reason is not very specific but enough to boot the debugger, but sometimes directly appear: HTTP 500-Internal server error is over, very affected debugging, after the CSDN and discussion, When it comes to debugging ASP programs that are easy to check for errors, it is summarized as follows:

1, win2kserver Management Web site do not close.

2, check the home directory options under the "Configuration" of the application debugging is not selected, (their use found, if the management of the Web site does not close, this is not selected can also appear in the browser error prompts.) ）

3, can modify 500-100.asp file to make the error hint more vivid

4, can be in the prior code error handling:
On Error Resume Next

5. Write the frame first
Write the code to the frame (not the picture) to write well, the framework has, more detailed code to write a handy ~ ~ ~

6, more use of CSS less table.
[COMETZG]: Detailed information can be on http://www.w3cn.org/web designer website Query

7, when debugging in the page screen, output some sensitive dongdong

Response.Write ""
Response.Flush ()
Response.End
[COMETZG]: This method is not the best, debugging when you can see some information, but after debugging need to find all the debugging-related output statements, but also very troublesome.

8, the program has session, try not to CTRL + N window.open a new window, lest the session value mixed.

9, set up debugging in the configuration of IIS virtual directory, send detailed error message to client.
IE tools ==> option ==> Advanced, cancel out display friendly HTTP error message

10, the collection of error code is very practical ...

VBScript syntax error
If the VBScript statement structure violates one or more VBScript scripting language syntax rules, a VBScript syntax error is generated.
Errors are usually generated when the program is compiled before executing the program. Here are 53 syntax errors:
