Origin Ver. and Service Release (Select Help-->About Origin): 8
Operating System: Win7
Hi,
i have two questions regarding labtalk.
1. Is it possible to read the Origin file name and use it as a variable? Because my files have the format YYMMDD and i want two extract the measurement date from the file name.
2. is it possible two excess the so called USerParameter ? Normally i use something like
"RangeName[U]$="(unit)";"
thx for your help in advance

(1) If by Origin file name you mean the name of the file you imported, then yes, that is in the page storage and can be accessed from script:
string str$ = Book1!page.info.system.import.filename$;
str$ = str.mid(n,6)$; // extract 6 characters starting at position 'n'
If the files were real-time generated, you can also get their date-time stamp:
jdn = page.info.system.import.filedate;
ty $(jdn,D10);
(2) You can use the Row Header text to access any parameter value:
string strP0$ = col(B)[UserParameter0]$;

thanks,
1) I need to get the name of the opj-file. This has nothing to do with import of files.
another question:
Is it possible to add new row headers like UserParameterXY?

If you are talking about the name of the current OPJ file, then that is available (without the .OPJ) in the G String Register variable:
string strProjectName$ = %G;
For custom headers ...
wks.userparam# = 1; // Turn ON the # user parameter row
wks.userparam# = 0; // Turn OFF the # user parameter row
string str$ = wks.userparam#$; // Read the # user parameter row header
wks.userparam#$ = "Some text"; // Write the # user parameter row header
where # starts at 1 and can go up to 127.
E.g.
wks.userparam1$ = Temperature;
wks.userparam1 = 1;
col(2)[Temperature]$ = 16.5K;

Thank you, this works great.
But i have a new questions:
Is it possible to check if a variable already excists? Or is it possible to give a default value a variable test$
Something like: only if test$ does not excist --> test$=default
Kind regards |

You can use the string functions like:
IsEmpty or GetLength
For example:
test$="default";
test.getlength()=;
test.getlength()=7
test.isempty()=;
test.isempty()=0
If the values returned are missing then you know the string variable does not exist. For example:
if(test.isempty() == NANUM) test$ = "default";

Thank you, this works fine for string objects, but don't work anymore for integers:
if(Temperature.isempty() == NANUM) Temperature = 5;
Is there another way for integer objects? |
