Sune, is there a max count it could be. For instance, 0-100 characters? Is there an infinite number possibly? Do you need the spaces between the characters counted?

I need to know how many character I have in a live text input, so I can adjust the text size to fill the full screen

Hi Sune,

There is not a Node that can do this, you're right, but there is a script:

VGetStringLength,VarName,String

You can assign your input to a variable with a Node then use this script to count that variable.

I hope this helps.

You can write Danish characters Æ Ø Å in the text input box in wd, but they come out as "<?>" PB text layer. can I get around it? so I can write the Danish characters

To get 'special characters' from the Widget Designer into Pandoras Box, you can use the "PB Text Unicode" Node.

I just tested this node with your characters and they worked.

Justyn,
I have a question. Where is the answer deposited? If the text read "Hello World" that would be 11 characters. I assume if you run the Script, you would end up with an answer of 11, just foggy on where that answer would show itself.

VGetStringLength,VarName,String VarName is the text you want to count, correct? Or is it where the answer of the script is placed. So if Text inside textbox1 how would this script be formulated assuming VarName is the variable

VGetStringLength,VarName,Textbox1 ?

Thanks!

The return is written to what ever Variable you would like - it's written as an Integer.
You can get the value from anywhere in WD - a String Variable or right from a Text Box if you'd like.
Just replace "string" with what ever you'd like to count.
For example:

Code: Select all
VGetStringLength,Length,textbox1.text


This will write an Integer with the number of characters (including spaces) to the Variable "Length" from Textbox 1.
