Hi all,
I'm writing a script in the "script after each file" section of the import wizard which is supposed to automatically plot my imported data. This works fine but I want to add a text label with text from a text file. So I somehow need to save the text from the file to a string, at which point I seem to fail. I don't get the readString command to work. Is there anything special to consider here or is there another way? I have the file path in a string. So the general idea should be: Declare a stdiofile object with this path, read the file and add this to the string I want to display, add the label to my plot, done. right?
regards

hi, J:


I think you were using something like the following in Labtalk

%K=test_set_longtext()$;


In Labtalk help file, it say each String Register can hold up to 260 characters at most(%A-%Y, except for some reserved ones, like %Y, %G etc), yet there is an exception, the %Z, so you may change your code to 

%Z=test_set_longtext()$; //%Z can hold longer text
or
strText$=test_set_longtext()$;


Hope it helps.

Ok, I wrote this .c file and it works fine when I start it from the command window in Origin. But when I return the string to my script it seems to be limited to a fixed number(267)of characters. Can anybody tell me why this is and how I can change this or what else to do?
regards

Dear sir/Madam,

The "script after each file" section of the import wizard only accept the LabTalk script, but the readString command and stdiofile object you used are Origin C functions.

Please try to create a .c file to define the functions you want using Origin C and then call the functions in the "script after each file" section.

Thanks,
Shirley
