ASP VBScript code gives "800a0005 Runtime error Invalid Procedure Call"

Question

The ASP code getting the below error while writing text to file.

Microsoft VBScript runtime error '800a0005'

Invalid Procedure call or argument

The Line in which i get the above error is below,

oFile.Write Chr(AscB(MidB(FileData,nIndex,1)))

The issue is caused when I am uploading a file. I will face this error only in Development environment. But the same code is working good in the Production environment. I could not understand why the error causes in Dev environment only.

Answer 1

You have a method with three nested function calls. Try breaking that up to see which call actually causes the error:

b = MidB(FileData, nIndex, 1)
i = AscB(b)
c = Chr(i)
oFile.Write c
