Creating BarCode using VB.Net. or Barcode and Vb.Net.
In this project we used font which is added to font at run
time. It is barcode font it convert entered text in form of Barcode value. There
is file name "rmad " this must be copied into Debug folder of project so that
font could be at installed run time. After generation of Barcode equivalent
value and image would be created in Debug folder automatically containing
Barcode value. You could download whole project as well as rmad file if need it
explicitly otherwise it is already in project Debug folder.
I am using visual studio 2010. I have converted this project
compatible to framework version 2.0 but still if it doesn’t work. Then just
follow the steps and create your own project. This code is acceptable to all
version of .Net.
Step 1: Create project and add 4 controls on form. That are
: one button name=button1, two label (no matter that what is name of second
label but you must name one label with name=Label1 (this label is must for
result if you are using code directly)) and one textbox with name=textbox1.
Step 2: Copy this while code to your class and also copy
namespace used. Copy carefully because if you would copy it in improper manner
then this code won’t be working for you.
Step 3: Copy ‘rmad’ file to Debug folder. ‘rmad’ file is available
for download here.
Solution code:
Imports System
Imports System.Drawing
Imports System.Drawing.Imaging
Public Class Form1
Dim PFC As
Drawing.Text.PrivateFontCollection
Dim NewFont_FF As
Drawing.FontFamily
Private Sub
Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles Button1.Click
Dim objBitmap
As New Bitmap(100, 50)
Dim
objGraphics As Graphics = Graphics.FromImage(objBitmap)
Dim objPoint
As New PointF(5.0F, 5.0F)
objGraphics.FillRectangle(Brushes.White, 0, 0, Width, Height)
objGraphics.DrawString(Me.TextBox1.Text,
CreateFont(Application.StartupPath & "\rmad", 20,
FontStyle.Regular, GraphicsUnit.Point), Brushes.Black, objPoint)
objBitmap.Save("Result.JPG",
ImageFormat.Jpeg)
Me.Label1.Font
= CreateFont(Application.StartupPath & "\rmad", 20,
FontStyle.Regular, GraphicsUnit.Point)
Me.Label1.Text
= Me.TextBox1.Text
End Sub
Private Function
CreateFont(ByVal name As String, ByVal size As Single, ByVal style As
Drawing.FontStyle, ByVal unit As Drawing.GraphicsUnit) As Drawing.Font
PFC = New
Drawing.Text.PrivateFontCollection
PFC.AddFontFile(name)
NewFont_FF =
PFC.Families(0)
Return New
Drawing.Font(NewFont_FF, size, style, unit)
End Function
End Class
Explanation:
Imports System.Drawing and Imports System.Drawing.Imaging
namespace is used for generation of image with barcode value.
Imports System namespace is used to import system control.
In this for installing font dynamically at run time and writing image file this
namespace is required.
Why installing font dynamically ?
Because it won’t lead in revealing secret to your client
that this is so simple to generate. Second and main reason is this; it won’t
result in error because whole job is of packaging properly no job required by
client of installing font. Download project from here. Download rmad from here. Output: Barform view.
