How to create and print a table using Drawing Vb.net

Question

I'm trying to recreate a label using Vb.net

I have this label that I want to recreate:

What I did till now: I tried to change lines but couldn't do to look like that, I don't even know how to arrange or move or add new column or rows.

Code that I found on the internet:

Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage 

        Dim ht As Single = 7 ' Table Height 

        Dim wt As Single = 5 ' Table Width 

        Dim r As Integer = 15, c As Integer = 2 ' Rows and Cols in Table 

        Dim Cht As Single ' Cell Height 

        Dim lst As Single ' last line drawn 

        Dim i As Integer 

        Dim p As Pen 

        Cht = CSng(Math.Round(ht / r, 2)) * c 

        lst = 0.5F + Cht ' 0.5->default margin 

        p = New Pen(Color.Black, 0.025F) 

        e.Graphics.PageUnit = GraphicsUnit.Inch 

        e.Graphics.DrawRectangle(p, 0.5F, 0.5F, wt, ht) ' border of the table 

        p.Color = Color.Blue 

        For i = 0 To CInt(r / c) - 1 ' lines in the table 

            e.Graphics.DrawLine(p, 0.5F, lst, 0.5F + wt, lst) 

            lst += Cht 

        Next 

 

    End Sub

I'm lost, I don't know how to create a similar label. What's the best way to do that?

Looks like you're progressing quite well. Just keep going with vertical and horizontal lines and you'll get there. — Andrew Mortimer, Mar 21 '22 at 12:59
@AndrewMortimer, thanks for your response, but has I said up there, I don't know how to manage that. — Abd Domingos, Mar 21 '22 at 13:20
DrawRectangle is drawing the outside black border. Then DrawLine is drawing the horizontal blue lines. Look up the help on those two methods and you should see what to change to make the lines vertical, or draw other rectangles. — Andrew Mortimer, Mar 21 '22 at 13:23
For the rounded corner outer rectangle, the following may be helpful: https://stackoverflow.com/questions/33853434/how-to-draw-a-rounded-rectangle-in-c-sharp — Tu deschizi eu inchid, Mar 21 '22 at 13:58
Instead of creating that by code, you can [Use the WinForms ReportViewer Control](https://learn.microsoft.com/en-us/sql/reporting-services/application-integration/using-the-winforms-reportviewer-control?view=sql-server-ver15) or Crystal Report to design and print your reports. — dr.null, Mar 22 '22 at 00:21

The following will help you get started in creating the label pictured in your OP.

I'll be using a Windows Forms App (.NET Framework) project with a Form named Form1.

Add the following Imports statements:

Imports System.Drawing.Drawing2D
Imports System.Drawing.Printing

To draw a rounded rectangle, we'll convert code from here to VB.NET.

RoundRect:

Public Function RoundRect(bounds As Rectangle, radius1 As Integer, radius2 As Integer, radius3 As Integer, radius4 As Integer) As GraphicsPath
    Dim diameter1 As Integer = radius1 * 2
    Dim diameter2 As Integer = radius2 * 2
    Dim diameter3 As Integer = radius3 * 2
    Dim diameter4 As Integer = radius4 * 2

    Dim arc1 As Rectangle = New Rectangle(bounds.Location, New Size(diameter1, diameter1))
    Dim arc2 As Rectangle = New Rectangle(bounds.Location, New Size(diameter2, diameter2))
    Dim arc3 As Rectangle = New Rectangle(bounds.Location, New Size(diameter3, diameter3))
    Dim arc4 As Rectangle = New Rectangle(bounds.Location, New Size(diameter4, diameter4))

    Dim path As GraphicsPath = New GraphicsPath()

    'arc - top left
    If radius1 = 0 Then
        path.AddLine(arc1.Location, arc1.Location)
    Else
        path.AddArc(arc1, 180, 90)
    End If

    'arc - top right
    arc2.X = bounds.Right - diameter2

    If radius2 = 0 Then
        path.AddLine(arc2.Location, arc2.Location)
    Else
        path.AddArc(arc2, 270, 90)
    End If

    'arc - bottom right
    arc3.X = bounds.Right - diameter3
    arc3.Y = bounds.Bottom - diameter3

    If radius3 = 0 Then
        path.AddLine(arc3.Location, arc3.Location)
    Else
        path.AddArc(arc3, 0, 90)
    End If

    'arc - bottom left
    'arc4.X = bounds.Right - diameter4
    arc4.Y = bounds.Bottom - diameter4
    arc4.X = bounds.Left

    If radius4 = 0 Then
        path.AddLine(arc4.Location, arc4.Location)
    Else
        path.AddArc(arc4, 90, 90)
    End If

    path.CloseFigure()

    Return path
End Function

Note: The code below demonstrates how to draw the outer rectangle, as well as, the first row. It also shows how to write text and use MeasureString to assist in calculating positions.

CreateProductLabel:

Private Sub CreateProductLabel(g As Graphics)
    'ToDo: add (additional) desired code

    Dim widthOuter As Integer = 600 'width of outer rectangle
    Dim heightOuter As Integer = 325 'height of outer rectangle

    Dim heightRow1 As Single = 80 'height of row 1
    Dim xPosRightRow1Col1 As Single = 200 'x-position of row1, column 1
    Dim xPosRightRow1Col2 As Single = 400 'x-position of row1, column 2

    'specifying '0', indicates to use the smallest width possible
    Using penDimGray As Pen = New Pen(Color.DimGray, 0)
        'create rectangle for outer border
        Dim outerRect As Rectangle = New Rectangle(0, 0, widthOuter, heightOuter)

        'draw outer rectangle
        Using path As GraphicsPath = RoundRect(outerRect, 10, 10, 10, 10)
            g.DrawPath(penDimGray, path)
        End Using

        'draw horizontal line
        g.DrawLine(penDimGray, New PointF(0, heightRow1), New PointF(outerRect.Width, heightRow1))

        'draw vertical line - right side of row1, col 1
        g.DrawLine(penDimGray, New PointF(xPosRightRow1Col1, 0), New PointF(xPosRightRow1Col1, heightRow1))

        'draw vertical line - right side of row1, col 2
        g.DrawLine(penDimGray, New PointF(xPosRightRow1Col2, 0), New PointF(xPosRightRow1Col2, heightRow1))
    End Using

    'size of the string(s); the height/width will be used in calculations
    Dim sizeProductionDate As SizeF = New SizeF() 'initialize
    Dim sizeShipper As SizeF = New SizeF() 'initialize
    Dim sizeCosigner As SizeF = New SizeF() 'initialize

    'draw text - headings
    Using penBlack As Pen = New Pen(Color.Black, 2)
        Using fontArial9Bold As Font = New Font("Arial", 9, FontStyle.Bold)
            Using brush As SolidBrush = New SolidBrush(Color.Black)
                'draw strings
                g.DrawString("Shipper:", fontArial9Bold, brush, 5.0F, 2.0F)
                g.DrawString("Cosigner:", fontArial9Bold, brush, xPosRightRow1Col1 + 2.0F, 2.0F)

                'determine size of specified string
                'the size (height/width) will be used in calculations below
                sizeShipper = g.MeasureString("Shipper:", fontArial9Bold)
                sizeCosigner = g.MeasureString("Cosigner:", fontArial9Bold)
            End Using
        End Using

        Using fontArial8Bold As Font = New Font("Arial", 8, FontStyle.Bold)
            Using brush As SolidBrush = New SolidBrush(Color.Black)
                'draw String - Production Date
                g.DrawString("Production Date:", fontArial8Bold, brush, xPosRightRow1Col2 + 2.0F, 2.0F)

                'determine size of specified string
                'the size (height/width) will be used in calculations below
                sizeProductionDate = g.MeasureString("Production Date:", fontArial8Bold)

                'draw string - Data de Producao
                'this string Is positioned at the same Y-position, but for the X-position, add the height of the previous string
                g.DrawString("Data de Producao", fontArial8Bold, brush, xPosRightRow1Col2 + 2.0F, 2.0F + sizeProductionDate.Height)
            End Using
        End Using
    End Using

    'draw product label information
    Using penBlack As Pen = New Pen(Color.Black, 1)
        Using fontArial9Regular As Font = New Font("Arial", 9, FontStyle.Regular)
            Using brush As SolidBrush = New SolidBrush(Color.Black)
                'draw strings
                g.DrawString("A 1 VERDE LIMITADA", fontArial9Regular, brush, 5.0F + sizeShipper.Width, 2.0F)
                g.DrawString("Plydor Seafood Limited", fontArial9Regular, brush, xPosRightRow1Col1 + 2.0F + sizeCosigner.Width, 2.0F)
            End Using
        End Using
    End Using
End Sub
