Re: rtf problem - nonbreaking hyphen breaks + other problems (REVISED)

I'm using a read only rich text box to format some text. In the text is a
series of phone numbers separated by a comma and a space. I don't want the
phone numbers to be split.

Here's what I've done. I replace '-' with '\_'which is supposed to be the
non-breaking hyphen. If I look at the string before it is stored in the
rtf it looks like ';555\_201\_1234, 555\_201\_1111, '. In the rtf it looks
like '555-201-1234, 555-201-1111, '.

When the form is displayed at the normal size, the series of phone numbers
are displayed correctly except that the space after the comma is at the
beginning of the next line.

When the form is made larger the vertical scroll bar is removed (the rtf
box fits on the screen) and the series of phone numbers split on one of the
hyphens screwing up the format. If there enough phone numbers to keep the
vertical scroll bar, the data is displayed correctly, except that the lines
start with a space.

When the form is restored to it's original size, the vertical scroll bar is
missing if it wasn't required on the larger window. If you set the cursor in
the rtf box and move the cursor down the vertical scroll bar appears.

I see 3 problems:

1. The rtf control string for a nonbreaking hyphen doesn't work.
2. If a line is split on a space the space should be at the end of the line.
3. Vertical scroll bar is missing when required.

Hi tsiGeorge,

Thanks for your post.

I do not think I understand your scenario well.

First, how do you store ";555\_201\_1234, 555\_201\_1111, " string in the
rtf? This statement:
this.richTextBox1.Rtf=@";555\_201\_1234, 555\_201\_1111, ";
will generate an " Invalid file format." exception

Second, defaultly, I do not know how your vertical scrollbar appears? I
think there is only single text in the richtextbox, which should not cause
the vertical scrollbar to appear.

Currently, I suggest you attach a sample project for us to demonstrate this
issue. Then we can understand your problem better. Thanks

(you may remember me from the MDI client problem)
Try this for the string
Dim I as integer
Dim S as string
For I = 0 to 25
S &= "555\_201\_1234, 555\_201\_1111, "
Next
S = S.Substring(0, S.Length-2)
RichTextBox1.rtf = "{\rtf1\ansi " & S & "}"

Create a MDI client form.
Set the rich text box width so that 3 phone numbers are displayed per line
and the height so the vertical scroll bar is active. Maximize the form and
then restore to the orignal size.

Hi George,

Thanks for your reproduce project.

With it, I can reproduce your #3 vertical scrollbar disappear issue.
Currently, I am not sure what internally cause out this problem, however,
we can workaround this issue with adding a refresh statement call after the
height changing. Like this:

Private Sub Form2_resize(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.SizeChanged
RichTextBox1.Size = New Drawing.Size(RichTextBox1.Size.Width, _
lblMsg.Location.Y - RichTextBox1.Location.Y - 8)
Me.RichTextBox1.Refresh()
End Sub

After adding this line of code, it should work well.

For #1 and #2, I think I still did not understand your point. When I run
the project, I can see certain phone number splitted on my machine like
this:
218-229-2908, 218-283-0932, 218-365-0064, 218-365-0843, 218-834-0781,
218-834-0783, 320-558-4021, 320-
558-4023, 320-692-4398, 320-692-4715, 320-983-2870, 320-983-6245,
507-423-1045, 651-257-2635, 651-462-
0649, 763-479-2503, 763-972-5894, 952-446-8167, 952-446-8169, 952-472-3782,
952-472-5089

For #2, can you show me you steps about how to force the line to splitted
by a space?

I will wait for your further feedback. Thanks

The refresh workaround worked.

On the splitting problems.
When the windows is a maximum size look at
218-834-0783, 320-558-4021, 320-
> 558-4023, 320-692-4398, 320-692-4715, 320-983-2870, 320-983-6245,
Notice that the phone number 320-558-4023 was split on 2 lines. But the
hyphens are nonbreaking hyphens. In rtf code \_ was used.

When the window is at the minimum size notice that the phone numbers are
slightly to the right of all the other values in the right column. If you
look at the value of the S variable (i think it's S) you will see it starts
with a space so that when the string is split on a space the phone numbers
still line up. It is very obvious that when the string is split on a space
the space is at the beginning of the line when the initial space is removed.
Hope this makes sense to you. The phone numbers should always be displayed in
nice columns.

Hi tsiGeorge,

Thanks for your feedback.

With your further feedback, I think I understand your problem.

First, nonbreaking hyphen is "\_" in RTF specification, not "\emdash", so I
have replaced all the "\emdash" with "\_" in your project. However, it
seems that this also does not work.

Second, I have also seen your space at the begining of each line problem.

For these 2 issues, I will spend a little more time into them, I will
update you ASAP. Thanks for your understanding.

Jeffrey,
Sorry about that. I've tried \_, \endash, \emdash and none of them worked.
Your would think an \endash would work since it isn't a hyphen but once it
gets loaded into the rtf variable they all look alike.

Hi tsiGeorge,

Sorry for letting you wait for so long.

I have contacted our product team for this issue, and below is their
feedback:
"It looks like the Unicode character richedit supports as a nonbreaking
hyphen is 8209: try replacing
320\_558\_4021
with
320\u8209?558\u8209?4021"

So I suggest you try to replace "\_" with "\u8209?" to see if this helps.
Thanks

Non-breaking space also doesn't work - any ideas for that one?

Thanks.

Jeffrey

Doesn't work at all. Shows up as an illegal character (small box).
