Problem with CreateTextFile 1

[paulparky]

I have a problem with CreateTextFile in that whenever I try to use a variable in the filename I get the error "bad filename or number".
The code I'm using is

outputfile = "//192.168.10.152/encoded/" & filenumber & ".enc"
Set objfso = Server.CreateObject("Scripting.FileSystemObject").CreateTextFile(outputfile,True)

If I replace "filenumber" with a literal string i.e outputfile = "//192.168.10.152/encoded/testfile.enc" it creates the file without problem, but as I need to use a variable name for the filename,does anyone have any ideas/pointers to resolve this.

try:

outputfile = "//192.168.10.152/encoded/"&TRIM(filenumber)& ".enc"

Are you certain that the value of filenumber is what you think it is? Is it a valid file name?

Try using Response.Write(filenumber) to see what value is being used.

Hi guys,
DotNetGnat - The Trim(filenumber) gives me the same result "bad filename or number"

TomThumbKP - the filename variable is a string consisting of Alpha and numeric characters upto 13 in length. If I put the same string as a literal the file creates without problem. I have displayed the variable name beforehand and cannot see any characters that would deem the filename invalid.

Can you do a Response.Write(outputfile) and paste what you get into this thread?

cheers

Either this statement:

"If I put the same string as a literal the file creates without problem."

or this statement:

"I have displayed the variable name beforehand and cannot see any characters that would deem the filename invalid."

Is incorrect. Since concatenating multiple strings results in a string literal.

the only option left for you to debug this is to use...

Response.Write

-DNG

 

[paulparky]

the code outputfile = "//192.168.10.152/encoded/" & fileNumber & ".enc"
response.write(outputfile) gives the result
//192.168.10.152/encoded/TXLU8393021.enc
but I get the error with this code.
If the code states outputfile = "//192.168.10.152/encoded/TXLU8393021.enc" I get no error and the file creates correctly.

 

[DotNetGnat]

try this:

outputfile = """ & "//192.168.10.152/encoded/" & fileNumber & ".enc" &"""

-DNG

Look for any nonprintable char in filenumber, if any.
[tt] response.write escape(trim(filenumber))[/tt]

Thanks guys. There was actually noprintable characters in there being picked up from the xml data source file. Sorted it now.
