How do I block the Space key?

  • Hi again

    i have this events to set a minimum of 3 characters length and a maximum of 15

    the thing is that i dont want to have Spaces, is there a way to block it? even if someone Paste a string with Spaces on it? or to not count the Blank Spaces as a char?

    what im trying to do is to verify the textbox has more than 3 characters but i dont want to count the blank spaces...

    any ideas?

    thanks again

  • You can use the regex system expressions.

    Remove all spaces from string ("\s" matches any whitespace, "g" = global, replaces all occurences):

    RegexReplace(TextBox.Text, "\s", "g", "")[/code:2ddr5qdt]
    
    Count number of spaces:
    [code:2ddr5qdt]RegexMatchCount(TextBox.Text, "\s", "g")[/code:2ddr5qdt]
  • Remove all spaces from string ("\s" matches any whitespace, "g" = global, replaces all occurences):

    ramones where did you find a list of the flags? I can't find it anywhere. The doc on this is ridiculously thin..

    do you know how to concat the flags together? if I wanted to remove whitespaces and "-" dashes? or do I have to do it as separate Actions? I actually want to remove all non alphas... is there a flag for that?

    What?

    Google "regex" will give you more results than you ever can read...

  • I'm sure he meant in C2 / the manual. But yeah regular expressions can be used in most programming languages and there are lots of guides out there.

  • RegExr is an online tool to learn, build, & test Regular Expressions(RegEx / RegExp).

  • For this you don't even need regex necessarily.

    replace(srctxt, " ", "")

    and if you wanna find out the length without spaces:

    len(replace(srctxt, " ", ""))

    Of course regex has it's advantage. It can also catch other whitespace characters in one go and replace them for you etc, like Ramones showed.

    oh javascript.. that was not clear. I'm a C/C++ person I haven't done much js. Still there should be a link in the doc to something like this and not assume users know the flags or know it's js.

    oh it's not js? it is it's own thing? well it's a standard I know nothing about, so good to know!

  • okay so these..

    \d Any digit character

    \w An alphanumeric character (“word character”)

    \s Any whitespace character (space, tab, newline, and similar)

    \D A character that is not a digit

    \W A nonalphanumeric character

    \S A nonwhitespace character

    . Any character except for newline
