    [VB2010] - RTF format: how change row height?:(

    i have these nice sub for insert a table:
    Code:
    Public Sub InsertTable(ByVal Rows As Integer, ByVal Columns As Integer, Optional ByVal ColWidth As Integer = 700, Optional ByVal RowHeight As Integer = 2000)        Dim _Rtf As String
            _Rtf = "\par"
            ' I Fixed the column size here you can change it on your own
            For row As Integer = 1 To Rows
                _Rtf &= "\trowd\trautofit1\trgaph108\trrh" & (RowHeight * row).ToString & "\trleft36" 'these last comand is the left row position
                'The following  For loop is just an example you make a list of columnWidth and  and you can assign it here
                For col As Integer = 1 To Columns
                    _Rtf &= "\clbrdrt\brdrdb\brdrsh\brdrs\clbrdrr\brdrdb\cellx" & (ColWidth * col).ToString
                Next
                _Rtf &= "\pard"
                _Rtf &= "\intbl\row"
            Next
            _Rtf &= "\pard"
            Dim tmpstr As String = Me.Rtf
            Me.Rtf = tmpstr.Insert(tmpstr.LastIndexOf("\par" & tmpstr.Chars(tmpstr.Length - 2)), _Rtf)
        End Sub
    i have read that the "\trrhN" RTF command is for change the row height and the 'N' is the size. if so why don't change the row height?

    Open in WORDPAD to see the changes. RTF changes every few years. It was 600 pages 10 years ago. You can download it.

    heres the result:
    Code:
    {\rtf1\ansi\ansicpg1252\deff0\deflang2070{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}\viewkind4\uc1\pard\f0\fs17\par
    \trowd\trgaph108\trleft36\cellx700\cellx1400\cellx2100\cellx2800\cellx3500\pard\intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \pard\par
    }
    big question: where is the "\trrhN" command?

    A quick observation showed me that your code should be fine. You do realize though that you must set the row height and width properties in Twips?

    A twip is 1/20 ( one twentyith ) of a point. 72 points are equal to one inch. Therefore 1440 twips are one inch (72 times 20)

    Also, have a look here :

    heres the new code:
    Code:
    "\trowd \trgaph108 \trqc \ltrrow \trleft3 \trrh" & (RowHeight * row).ToString & " \trhdr \trkeep"
    and what the textbox show me:
    Code:
    {\rtf1\ansi\ansicpg1252\deff0\deflang2070{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}
    \viewkind4\uc1\pard\f0\fs17\par
    \trowd\trgaph108\trleft3\trqc\cellx700\cellx1400\cellx2100\cellx2800\cellx3500\pard\intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \intbl      \cell\cell\cell\cell\cell\row
    \pard\par
    }
    i see 2 bad things
    1 - the cell have the standard height;
    2 - the textbox don't show me the "\trrh" comand
