Using Replace to replace data in a file does not work (Solved)

Hello LC friends,
I thought I could replace data in a file directly with the replace command. But nothing happens. I also get no error information.
Any ideas? Below is the code snippet I made.
Variable tFileURL holds the Path and filename e.g. C:/foldername/filename.html
variable tGraphLabel holds the name of the graphic that should replace ***GraphicLabel*** in the file
Code: Select all
put quote&" file: "&tFileURL"e into tURLInfo
try
replace "***GraphicLabel***" with tGraphLabel in URL tURLInfo
catch tError
end try
Regards,
Paul

Hi Paul,
you end with this in tUrlInfo ->
" file: tFileURL" and LC obviuosly does not like this.
Do this:
Code: Select all
...
try
## put quote&" file: "&tFileURL"e into tURLInfo
replace "***GraphicLabel***" with tGraphLabel in URL ("file:" & tFileURL)
catch tError
end try
...
Best
Klaus

This needs to be done by reading the file in, making the changes, and writing it back out. (I think...)
Or by specifying the location of your placeholder text and putting the replacement into that location of the file, eg
Code: Select all
put "new text" into char 1 to 17 of line 55 of url ("file:" & tFileURL)
Or depending on your circumstances and need, you might the power of *merge* quite useful. If you have a template file with placeholders marked with square brackets
Code: Select all
standard text [[tGraphLabel]] more text
then the expression in the merge placeholder will be merged (ie the tGraphLabel variable will be evaluated and its value replaced in the merged result. You can then write it out to a new file.

You have to change some parts of your script to get it working
Code: Select all
put "file:"&tFileURL into tURLInfo
try
replace "***GraphicLabel***" with tGraphLabel in URL tURLInfo
catch tError
end try
Although that works, i would use value("tURLInfo") to reference to the content of tURLInfo.
Code: Select all
replace "***GraphicLabel***" with tGraphLabel in URL value("tURLInfo")

Thank you all for helping me.
It now works.
What a difference a small code change and some LC forum friends can make
.
