where is the cursor in a rictextbox???

[bany]

hello,

(sorry for my english...)

I would like know if it's possible to get the position of the cursor( text
and not a mouse position!)

example: line 15, colonne 7 in my richtextbox...

thank for your help

Jean Jacques,

I doubt that this functionality would actually make sense. If you think
about it, as this is a rich text box, the text can be different font and
sizes for each character. Therfore there can not be a persistant definition
of 'column' . Therfore I would not expect any in built function to exist.

However, you could write something yourself I suppose.

Mhm... It makes sense in a code editor, for example something like
VS.NET's code editor.

P/invoke on 'SendMessage' + 'EM_LINEFROMCHAR'/'EM_EXLINEFROMCHAR'.
Sorry, I don't have a sample and an idea for getting the column number
(but there is a way to do that).

In the code editor, the characters are ll in the same fonr and size.

Yep. And you can select a font like Courier New in a RichTextBox too.

Some text editors are based on the RichTextBox control...

I still maintain that a column by definition is a vertical line. Therfore,
'column' does not apply if they text is not lined up. If you were to say
row, this also does not apply in a RTB, because lines are wrapped, therefore
the definition of 'Row' does not apply in a RTB who's lines may wrap.

You can turn off line wrapping. That's not the problem. Even if there
was line wrapping and different fonts, (idx_x, idx_y) can be used to
specify the position of a character.

OK, lets say I give in on the 'Row' , a Colum is still a column. Even if
the fonts are the same, fonts which support Kerning would skew the colum
depending on the letters used.

Loosely speaking you may get "Almost Columns", but it would be better to
refer to horizontal position, not Column Number.

or magazine is divided:
I didn't have time to read the whole article - just the first column.

The 3rd character in the line will still remain the 3rd character,
regardless of which font(s) is/are used to display it.

Mhm... For me, it doesn't matter if we are talking about rows or
columns, I think everybody understands what the OP is referring to.

Actually no we dont. How do you know that he did not want to use the RTB in
some other way. he may have wanted to show a maxtrix of values for example.

And yes the 3rd character will remain the 3rd character, however the 3rd
character on the 1st row may not be in the same position as the 3rd
character on the 2nd row. In this case viewing characters 3 would not
result in a column but a skew.

Just like chr 3 remaining chr 3, a column is a column.

Mhm... I would not use the RichTextBox to display a matrix.

ACK.
