Ok - I'm about to pull my hair out.
I am using fileexists() function to determine whether a image file exists on
the server. When I type in the path it works fine, but when I use a variable it
always returns false.
My code is like this:
cfset variables.ImageSource =
To troubleshoot, one, the pounds are not needed so I'd take those out.
Two, in cfelse, what is the value of:
cfoutput#variables.ImageSource#cfoutput do something else
In other words, what is the variable's value as soon as you hit cfelse.

try
cfif FileExists('#variables.ImageSource#')
or
cfif FileExists(variables.ImageSource)

We use this all over, though you don't need the hash marks.

Tried:

cfif FileExists('#variables.ImageSource#')
cfif FileExists(#variables.ImageSource#)
cfif FileExists(variables.ImageSource)
None of which works.

The value of the variable is:
C:\somepath\filename.png
Which is correct.

When I was testing this a few minutes ago, I noticed that when I made
changes to the fileExists function, the file wasn't being recompiled -
I had to make some other change (any other change) and save the file
again.
How can you tell when a template is recompiled?
I made some changes and tried again. Still no dice?
I'm outputting the variable and it looks correct, unless there is a control
character or something in the string that I cannot see. I am thinking this
might be the issue. The file name was
It is the correct path and file name.
C:\somepath\filename.png
I am thinking that there may be a control character of something that I cannot
see. I am reading the filename.png from SQL Server.

You can attempt to identify the compiled file in the WEB-INF/cfclasses
subdirectory, and look at the timestamp.

The fileExists function expects a string literal. Wrap
Took the hash marks out. Put quotes, trimmed the variable, checked the length
of the file name to make sure there weren't any control characters or anything.
My code is very straight forward.

I was digging into Adobe's docs to see if something change. 1. Their examples
are terrible. It's amazing anyone learns anything from those. 2. Nothing noted
about changed behavior.
So I took their example and fixed it so it would work. Try this.

You said that When I build the file path from the database fields it will not
work. . Lets see that code. Something may not be what it seems to be.

Have you tried checking the length of the string? Sometimes, you get a
CR/LF at the end with Excel.

Well thats the problem alright. Your putting CFOUTPUT in the cfset tag. It's
getting used as a literal.
This is the better way to do this

Alternately you could do this:

Thank you so much. What a newbie error. I had tried it without the cfoutput
and was at the point of frustration I was coding recklessly.
That fixed it!
