[SOLVED] Length Not Working Like It Should

[pixelink]

This is what I am trying....

Code: Pascal  [Select][+][-]

1. if Length(txtTime.text) < 8 then
2.  
3. And this one...
4.  
5. if UTF8Length(txtTime.text) < 8 then
6.  

Neither of them returns a proper number. I only get 0
I read that is was a bug... is this still the case or has it been fixed?
OR
Am i doing something wrong again.

What is txtTime.text ?

I have similar problem

Code: Pascal  [Select][+][-]

1. writeln(i);

Outputs 5, but  expected is 3.

Are you saying that when i is 3 writeln(i) prints 5? This joke is too late for April Fools Day!

As it should be obvious, something else is at fault here: writeln(i) just writes whatever value i has. If it's 5 but should be 3, look wherever i is set.

A text control field of course.

What kind of "text control field". Give us the class name, at least!

Also, you may try to insert a line with:
    ShowMesageFmt('"%s"', [txtTime.text]);
to ascertain whether it really contains something.

Finally, where did you read about this "bug"? We can't know if there really was a bug and, if so, whether it has been quashed without knowing what you're talking about.

I ask because I've been using various TCustomEdit descendants and other controls with Text properties for years (including using Length and LengthUTF8) and I've never seen anything remotely related to what you're supposedly seeing.

it is a plain old text field.
I need to evaluate the time that is entered into the field.

Did you notice that at first your question was taken as a joke? It is clear that "if Length(txtTime.text) < 8 then " is true when the length of string is less than eight (for example zero, as you mentioned). So without a detailed explanation of what exactly "bug" it will look like a joke.

"Text field" could also be a "field" of a database. But TField has no ".Text" property - or has it? So I have to look into the sources whether there is such a property. Yes. it has.

Hmmm... Or do you mean: TEdit?

Why do keep us guessing what you mean? If you'd say "TEdit" everything would be clear.

OK, since you don't care to say what class it's I'll assume is a TEdit or sibling. Find attached a small test and the results, showing that it does in fact work.

We can't help you adequately unless you give us more (detailed) info.

I have similar problem

Code: Pascal  [Select][+][-]

1. writeln(i);

Outputs 5, but  expected is 3.

Expected is  √-1

1) It is a TEdit text box.  And the property is Text not Caption
2) The length is returning the value of 0
3) I don't remember where I saw that it was a bug, but it was on this forum somewhere

If the text string in the TEdit.Text is "3:00 PM"
Length should be returning 7 characters, not 0

Of course. We can all read your mind.
