Hi,
We have titles that are sometimes long and break in undesireable places. We would like to be able to insert no-break spaces in the strings before they are put in a TextFrameEx.Paragraph.Portion.Text.
I have tried to do this but the no-break spaces do not seem to make it to the PowerPoint (pptx).
Any clues about where I might look or try to do would be appreciated.
Brad
Dear Brad,
I feel sorry to share that I have not been able to completely understand the issue specified by you. Can you please elaborate the problem to some more extent.
Thanks and Regards,
Hi Mudassir,
The problem was in some of the VB string handling routines. I made a work around which used the Replace function not attached to String. Also had to break up the string since I could not find a function that allowed replacement in just part of the string.
For any others that want this functionality:
Public Shared Function noBreaksAtEnd(ByVal s As String) As String
Dim cNBSpace As String = " " 'non break space
Dim cOld As Char = " " 'normal space
If s.Length > 20 Then
s = charReplace(s, cOld, cNBSpace, s.Length - 12, s.Length - 1)
End If
Return s
End Function
Public Shared Function charReplace(ByVal s As String, ByVal cOld As Char, ByVal cNew As Char, ByVal iBeg As Integer, ByVal iEnd As Integer) As String
Dim sBeg As String
Dim sMid As String
Dim sEnd As String
Dim i As Integer
sBeg = s.Substring(0, iBeg)
sMid = s.Substring(iBeg, iEnd - iBeg + 1)
sEnd = s.Substring(iEnd + 1)
'HttpContext.Current.Trace.Warn(sBeg + "-" + sMid + "-" + sEnd)
sMid = Replace(sMid, cOld, cNew)
Return sBeg + sMid + sEnd
End Function
Hi Mudassir,
Another problem has developed with the non-breaking characters (at least the hyphen).
When I create a jpg from a pptx using GetThumbnail, the non-breaking hyphens are not shown in the jpg. I am attaching an example. Notice the hyphen is missing in 'Anti-Static' in the jpg.
