Setting Text Style Based on Word in Field

[J316]

Hi Folks,

Having trouble with this as I'm just getting started in LC.
With a field named month listing the following:

Month 1
2nd
4th
etc.
Month 2
12th
17th
etc.

I am wanting to set the textStyle to link for all lines that contain the word "Month".
Have been modifying the below script without success.

on mouseUp
put field "month" into tmonth
repeat with x = 1 to the number of lines in tmonth
if line 1 contains "Month" then
set the textStyle of it to link
put tTest22 into field "test22"
end if
end repeat
end mouseUp

Any help much appreciated!

Hi J316,

1. welcome to the forum!

2. This should do the trick, please note my comments!

Code: Select all

on mouseUp
   put field "month" into tMonth
   
   ## To speed up things when working with fields, we lock the screen!
   ## Since fields are quite complex to draw, we might see LC working line by line otherwise :-D
   lock screen
   repeat with x = 1 to the number of lines of tmonth
      ## if line 1 contains "Month" then
      ## You want to check ALL lines and not only line 1, right?

      ## Looks like all the lines START with Month, so I used ...BEGINS WITH... here, if not chage back to ...CONTAINS...
      if line i of tMonth begins with "Month" then
         
         ## set the textStyle of it to link
         ## IT is not used anywhere in this handler so it may contain 
         ## ANYTHING (from an earlier command/functoin) or NOTHING!
         ## We change the according line in the actual field:
         set the textstyle of line i of fld "Month" to "link"
         
         ## tTest222 is also not defined in this handler so you will see the string tTest 22 in fld "test22"
         ## put tTest22 into field "test22"
      end if
   end repeat
   
   ## Done!
   unlock screen
end mouseUp

Try this.

Code: Select all

on mouseUp
   put field "month" into tmonth
   repeat with x = 1 to the number of lines in tmonth
      if line x of tmonth contains "Month" then
         set the textStyle of line x of tmonth to link
         put tTest22 into field "test22"
      end if
   end repeat
end mouseUp

Hi Tom,

...
set the textStyle of line x of tmonth to link
...
"tMonth" is a variable!

Hey again Klaus,

I guess I'm a little confused about the lines in fields from your comment about All of them starting with Month. My assumption was for the
below example that only lines 1 and 5 begin with Month...as they would appear in the contents of a field?? I am trying to have "Month 1" and "Month 2" only to become links.

Month 1
2nd
4th
etc.
Month 2
12th
17th
etc.

I did try the script with "starts with" and "contains", no quotes, of course. It returned an error both ways:
execution error at line 12 (Chunk: error in range start expression),char 1
This is the line in the script: if line i of tMonth contains "Month" then

Thanks much for the help. I know this is elementary for you folks, but I will get better...promise!

Hi J316,

sorry, I made a little typo in my script, lets see if you can spot it, too:

Code: Select all

...
 repeat with x = 1 to the number of lines of tmonth
      if line i of tMonth begins with "Month" then
      ...
       set the textstyle of line i of fld "Month" to "link"
...

Ah! Klaus,

Thanks for the little challenge...I do appreciate it. Sorry about the delay...my day job got in the way! I changed the i's to x's since the initial repeat was defined that way. I am also assuming, and will try i for this also, it is like a variable and can be most anything one would like it to be as long as one is consistent in the script.?

I also removed the quotes from:
set the textstyle of line x of fld "Month" to "link"
making it:
set the textstyle of line x of fld "Month" to link --I suppose this is optional?

All worked fine and I really appreciate it.

Klaus...this wasn't actually my first post. I saw some folks viewed my first one, but did not respond. I assumed I just ask a stupid question or maybe it wasn't posted in the correct place in the forum. Would you mind looking below at my first post and tell me if it's a stupid question, in the wrong place or, if you will, address it. I really wanted to make a decision on the below item before I got too far along in my efforts. Thanks again, very much! And here it is:

"Hi Folks,

This is my first posting a question here and thanks for all you are doing to help.

I am reading about retrieving text files that are located on a server, but am not sure what the most efficient way to proceed might be. My app is almost exclusively dealing with text. I have created several fields for displaying the text stored in the field contents, but I'm concerned that with the volume of text I will ultimately have, it may slow down the app. I am not interested (at this point) in writing to the server. In reading, I saw a suggestion of using the "load" command as being asynchronous and also being able to dump the cache. But I also wondered if using FTP would be as good a choice. I'm just too new to this stuff (about a month in) to trust my own instincts.

I have a text file stored on my web server, but forum says I can't post web links. Need help with that for future I suppose?

Might you point me in the direction you think is best for me to proceed? Thanks upfront for any help and again for all you do!

it actually IS a variable, a temoprary one, but a real and valid variable!

I also removed the quotes from:
set the textstyle of line x of fld "Month" to "link"
making it:
set the textstyle of line x of fld "Month" to link --I suppose this is optional?

No, that is correct syntax with quotes!
If in doubt, always take a look into the dictionary!
