Guoqi Zheng

Dear Sir,

I am trying to use do a upload function on my site. I got a upload class
from Internet. However, sometimes, it works, sometimes, it give me the
following error.
Microsoft VBScript runtime error '800a0005'

Invalid procedure call or argument

/viplogin/include/UploadClass.asp, line 136

Line 136 is following

For nIndex = 1 to LenB(FileData)
oFile.Write Chr(AscB(MidB(FileData,nIndex,1))) --- Line 136
Next


Can someone help me out??

Hi Guoqi,

Ik kan me alleen bedenken dat er iets fout gaat met de SET in de regel
ervoor, waardoor de write niet lukt.

Bijvoorbeld een missende "/" tussen sPath & FileName ?

Hi, Evertjan

Thanks for your quick reply. I have been in Holland for 3.5 years, however,
I still can not understand Dutch.

The variable "sPath" is always checked to make sure that it end with a "\".
So I think it wasn't that problem.

The funy thing is that somet imes it is ok, some times, it gives that error

Any one has an idea??
