[Openroad-users] FW: Re: BufferText

[Laverty, Danny]

I found this an interesting and potentially useful feature - I wanted to use it to let our users know how many characters they still had left when entering data into certain text fields.  It works perfectly if only alphanumeric characters are used but I hit a bug where the number of characters used (and, therefore, the number of characters left) is incorrect if the Return key (HC_NEWLINE) is used - something our users do regularly as they format many of their text fields to show paragraphs.  My intended workaround is to use "traffic lights" rather than numbers, but I would prefer to combine both.

If you are thinking of using similar functionality, the bug has been raised under Issue 126468 and a fix will be forthcoming in due course.

Danny

Andrew,

To speed things up - you could also remove the fieldobject creation / destruction in the event block and instead use the trigger field and string object.

e.g: -

ON BUFFERCHANGED comments =

DECLARE

ENDDECLARE

BEGIN

    tally = EntryField(CurFrame.TriggerField).BufferString.Length;

END

Hi Simon,

There is more work in using keypress.

BufferText is alot easier and now with using On BufferChanged its great.

ON BUFFERCHANGED comments =
declare
    fo = FieldObject;
{
    fo = Field(comments);
    tally = Length(EntryField(fo).BufferText);
}

Regards,
Andrew.

What about the KeyPress event?  Would that be any better?

I believe that KEYDOWN fires before the character is added to or

removed from the buffertext. You could check what key was pressed and

add 1 if the key wasn't backspace or delete, and subtract 2 if

backspace or delete was pressed. Too bad there is no KEYUP event,

which is what you really want... an event that fires after the buffer

is changed.

Hi All,



OR4.1 on WinXp.



Anyone out there displaying a tally or character count of a multiline

entryfield as a user types?



I have tried using buffertext but when the user starts typing the

length of the buffertext is one less than what is displayed.



If the user backspaces once then the count goes up by one. If

backspaces again then the count goes down by one, but the count does

not represent the actual number of characters displayed in the field.



My field event look like this:



ON KEYDOWN comments =

declare

    fldobj = fieldobject;

{

    fldobj = field(comments);

    tally = length(EntryField(fldobj).BufferText);

}



I have also tried BufferString but get the same behaviour.

My comments field is a varchar(2000).



Any help would be greatly appreciated.



Regards,

Andrew.
