I have a richtextbox that is filled with the result of a SqlServer query on vb.net. The result joins all items horizontally and when reaching the richtextbox margin it will wrap the line.
Code:
'Function of loading data into Datagridview
Private Sub entregue()
dgv1.Rows.Clear()
Cursor.Current = Cursors.WaitCursor
Dim consultando As New frm_aguarde_consultando
consultando.Show()
' Set cursor as hourglass
Application.DoEvents()
Dim ano, mes, dia As Integer
Dim var1data, var2data As Date
Dim dinicio, dfim As String
var1data = DateTimePicker1.Value '.ToString.Substring(0, 10)
dia = var1data.Day
mes = var1data.Month
ano = var1data.Year
dinicio = ano & "-" & mes & "-" & dia
var2data = DateTimePicker2.Value
dia = var2data.Day
mes = var2data.Month
ano = var2data.Year
dfim = ano & "-" & mes & "-" & dia
Using sqlcoon As SqlConnection = GetConnectionsql()
Dim READER As SqlDataReader
'ENTREGUE
Try
sqlcoon.Open()
Dim Query As String
Query = "select MOV_IDENTIFICACAO,MOV_PROTOCOLO,MOV_DATADOC,MOV_SITUACAO,MOV_DATAENTREGA,MOV_HORAENTREGA,MOV_SITEND_CODIGO
from movimento where MOV_DATADOC = '" & dinicio & "'
AND MOV_CLI_CODIGO = '" & txtcod.Text & "' AND MOV_SITUACAO = '" & "E" & "'
AND CAST(MOV_DATAENTREGA AS DATE) = '" & dfim & "' "
Dim COMMAND As SqlCommand = New SqlCommand(Query, sqlcoon)
READER = COMMAND.ExecuteReader
While READER.Read
Dim MOV_IDENTIFICACAO = READER("MOV_IDENTIFICACAO")
Dim MOV_DATADOC = READER("MOV_DATADOC")
Dim MOV_DATAENTREGA = READER("MOV_DATAENTREGA")
Dim MOV_PROTOCOLO = READER("MOV_PROTOCOLO")
Dim MOV_SITUACAO = READER("MOV_SITUACAO")
Dim MOV_SITEND_CODIGO = READER("MOV_SITEND_CODIGO")
dgv1.Rows.Add(MOV_IDENTIFICACAO, MOV_PROTOCOLO, MOV_DATADOC, MOV_SITUACAO, MOV_DATAENTREGA, MOV_SITEND_CODIGO)
End While
READER.Close()
sqlcoon.Close()
For Each linha In dgv1.Rows
Dim altura As Integer = 17
linha.height = altura
Next
If dgv1.Rows.Count >= 0 Then
' Set cursor as default arrow
Cursor.Current = Cursors.Default
' Hide the please wait form
consultando.Hide()
End If
Catch ex As SqlException
MessageBox.Show(ex.Message)
Finally
' sqlcoon.Dispose()
End Try
sqlcoon.Open()
Try
For r As Integer = 0 To dgv1.Rows.Count - 1
Dim COMMAND3 As SqlCommand
Dim READER3 As SqlDataReader
Dim Query_3 As String
Query_3 = "select IMOV_CODIGORECBTO from imovimento where IMOV_MOV_IDENTIFICACAO ='" & dgv1.Rows(r).Cells(0).Value.ToString & "'"
COMMAND3 = New SqlCommand(Query_3, sqlcoon)
READER3 = COMMAND3.ExecuteReader
While READER3.Read
Dim IMOV_CODIGORECBTO = READER3("IMOV_CODIGORECBTO")
'DataGridView1.Columns(6).HeaderCell.Value = "ID"
dgv1.Rows(r).Cells(6).Value = IMOV_CODIGORECBTO
End While
READER3.Close()
Next
dgv1.Sort(dgv1.Columns(6), ListSortDirection.Ascending)
sqlcoon.Close()
Catch ex As SqlException
MsgBox(ex.Message)
End Try
End Using
End Sub
'Function of loading data into Richtextbox
Private Sub preenchimento_rchrelatorio()
Dim entregue = "ENTREGUE"
rchrelatorio.Text += entregue & Environment.NewLine & Environment.NewLine
For r As Integer = 0 To dgv1.Rows.Count - 1
'richtextbox
rchrelatorio.Text += dgv1.Rows(r).Cells(0).Value & " "
Next
Dim totalentregue = "TOTAL: " & dgv1.Rows.Count
rchrelatorio.Text += Environment.NewLine & Environment.NewLine & totalentregue & Environment.NewLine & Environment.NewLine
end sub
Result:
How can the spacing between the lines of this rich text box be increased so that it looks like this:
Is there any possible way to achieve the result on vb.net ? I saw many forms in C# but I couldn't convert.
To be able to solve this way:

' Type of line spacing. To use this member, set the PFM_SPACEAFTER flag in the dwMask member. This member can be one of the following values.
' 0 - Single spacing. The dyLineSpacing member is ignored.
' 1 - One-and-a-half spacing. The dyLineSpacing member is ignored.
' 2 - Double spacing. The dyLineSpacing member is ignored.
' 3 - The dyLineSpacing member specifies the spacingfrom one line to the next, in twips. However, if dyLineSpacing specifies a value that is less than single spacing, the control displays single-spaced text.
' 4 - The dyLineSpacing member specifies the spacing from one line to the next, in twips. The control uses the exact spacing specified, even if dyLineSpacing specifies a value that is less than single spacing.
' 5 - The value of dyLineSpacing / 20 is the spacing, in lines, from one line to the next. Thus, setting dyLineSpacing to 20 produces single-spaced text, 40 is double spaced, 60 is triple spaced, and so on.
Dim ruleNum As Byte
' returns ruleNum as the number input by the user,
' or 255 if user input is bad

SelLineSpacing(rchrelatorio, ruleNum, 72)

SelLineSpacing(rchrelatorio, ruleNum, 100)
Case Else
MessageBox.Show("rule number must be between 0 amd 5")
End Select
End Sub
End Class
With the code above, at the moment when the richtextbox (rchrelatorio) is filled with the text and then the button is pressed, it generates a dialog box where it asks the spacing size between 0 and 5, and then just run to celebrate.
Important detail.
a problem if in case you want to print the formatted content, you will have to use a shipping method that does not change the configured richtextbox formatting.
