ASP Tutorial: The virtual directory can not upload pictures

There are so many problems today, one problem has been solved, another problem is coming out. Looks like a new one. As the title, I used the "Wind no component upload class 2.08 Beat" site with the main directory test use of all normal, changed to virtual directory, you can not upload pictures. Alarm content:
Microsoft VBScript run-time Error "800a0005"

Invalid procedure call or parameter: "Instr"

\uploadclass.asp, line 174
Then went to Baidu inside a few good several related articles, finally found the solution. Put if Instr (Inttemp,strtemp, ".") <>0 then changed to If Instr (inttemp,strtemp) <>0 then can be viewed in the following figure found in the article said, can not pass the RAR, do not know is not, there is no test, the back to fill this solution.
