How to display barcode images onto Pocket PC, Windows CE and Windows Mobile forms

Prerequisites
  • Neodynamic Barcode Professional for .NET Compact Framework
  • Microsoft .NET Compact Framework 2.0 (or greater)
  • Microsoft Visual Studio 2005 (or greater)
This walkthrough illustrates how to easily display linear (1D) and 2D barcode images onto Smart Device forms in Pocket PC, Smartphone, Windows CE and Windows Mobile projects leveraging .NET Compact Framework technologies.
During the course of this walkthrough, you will accomplish the following activities:
Display directly barcode images onto a form by using Barcode Professional UI controls
Follow these steps:
  • Install Barcode Professional for .NET Compact Framework and configure it in Visual Studio 2005 as is described in the "Getting Started > Visual Studio Configuration" topic in the product help.
  • Open Visual Studio 2005 and create a new Smart Device project such as Pocket PC 2003
  • Displaying Linear (1D) barcodes, for example Code 128
    • Open Visual Studio Toolbox and drag & drop the Barcode1D control as is shown in the following figure:
      Dragging & dropping Barcode1D control from Visual Studio Toolbox
    • Specify the Linear (1D) barcode Symbology/standard you want to use by setting up the Symbology property of Barcode1D control just dropped onto the form. For example the following figure shows the setting for encoding Code128
      Setting up Symbology property of Barcode1D control
    • The value to encode is specified by setting up the Code property of Barcode1D control and by default it's "123456789"
    • The Text property of Barcode1D control can be used to add additional text you want to draw on the barcode image. Example, you could set it to "Employee ID"
    • Barcode related dimensions are specified by setting properties like BarHeight, BarWidth, BarRatio, etc (all dimension values are measured and must be specified in inches). IMPORTANT: Please refer to the Barcode Professional help for more information about the settings for each standard. Look for "Barcode Symbology Information Center" topic.
    • (Optional) All the settings can be made by writing code in your preferred .NET language such as VB.NET or C#. For example, you could specify all settings in the Form_Load event procedure like follows:
      Visual Basic .NET 
      'Temporally suspend drawing

Me.barcode1D1.SuspendDrawing()
'Set barcode symbology

Me.barcode1D1.Symbology = Neodynamic.CF.Barcode1D.Symbology1D.Code128
'Set value to encode

Me.barcode1D1.Code = "123456789"
'Set additional text

Me.barcode1D1.Text = "Employee ID"
'Set dimensions

Me.barcode1D1.BarWidth = 0.01F
Me.barcode1D1.BarHeight = 0.5F
'...
'Redraw barcode

Me.barcode1D1.ResumeDrawing()
      Visual C# .NET 
      //Temporally suspend drawing
this.barcode1D1.SuspendDrawing();
//Set barcode symbology
this.barcode1D1.Symbology = Neodynamic.CF.Barcode1D.Symbology1D.Code128;
//Set value to encode
this.barcode1D1.Code = "123456789";
//Set additional text
this.barcode1D1.Text = "Employee ID";
//Set dimensions
this.barcode1D1.BarWidth = 0.01f;
this.barcode1D1.BarHeight = 0.5f;
//...
//Redraw barcode
this.barcode1D1.ResumeDrawing();
    • That's it. Build your project and test it. You should get something like follows:
      Testing Barcode1D control in Pocket PC Emulator
  • Displaying 2D barcodes, for example Data Matrix
    • Open Visual Studio Toolbox and drag & drop the Barcode2D control as is shown in the following figure:
      Dragging & dropping Barcode2D control from Visual Studio Toolbox
    • Specify the 2D barcode Symbology/standard you want to use by setting up the Symbology property of Barcode2D control just dropped onto the form. For example the following figure shows the setting for encoding DataMatrix
      Setting up Symbology property of Barcode2D control
    • The value to encode is specified by setting up the Code property of Barcode2D control and by default it's "123456789". Notice that Code property is not displayed in 2D barcode symbologies!
    • The Text property of Barcode2D control can be used to add additional text you want to draw on the barcode image. Example, you could set it to "Card ID"
    • Barcode related dimensions are specified by setting properties like DataMatrixModuleSize, BarHeight, BarWidth, BarRatio, etc (all dimension values are measured and must be specified in inches). IMPORTANT: Please refer to the Barcode Professional help for more information about the settings for each standard. Look for "Barcode Symbology Information Center" topic.
    • (Optional) All the settings can be made by writing code in your preferred .NET language such as VB.NET or C#. For example, you could specify all settings in the Form_Load event procedure like follows:
      Visual Basic .NET 
      'Temporally suspend drawing

Me.barcode2D1.SuspendDrawing()
'Set barcode symbology

Me.barcode2D1.Symbology = Neodynamic.CF.Barcode2D.Symbology2D.DataMatrix
'Set value to encode

Me.barcode2D1.Code = "123456789"
'Set additional text

Me.barcode2D1.Text = "Card ID"
'Set dimensions

Me.barcode2D1.DataMatrixModuleSize = 0.04F
'...
'Redraw barcode

Me.barcode2D1.ResumeDrawing()
      Visual C# .NET 
      //Temporally suspend drawing
this.barcode2D1.SuspendDrawing();
//Set barcode symbology
this.barcode2D1.Symbology = Neodynamic.CF.Barcode2D.Symbology2D.DataMatrix;
//Set value to encode
this.barcode2D1.Code = "123456789";
//Set additional text
this.barcode2D1.Text = "Card ID";
//Set dimensions
this.barcode2D1.DataMatrixModuleSize = 0.04f;
//...
//Redraw barcode
this.barcode2D1.ResumeDrawing();

Generate barcode images by using Barcode Professional classes and then display them onto a form by using a PictureBox control
Follow these steps:
  • Install Barcode Professional for .NET Compact Framework.
  • Open Visual Studio 2005 and create a new Smart Device project such as Pocket PC 2003
  • Displaying Linear (1D) barcodes, for example Code 128
    • Open Visual Studio Toolbox and drag & drop a PictureBox control and set its SizeMode property to CenterImage
    • Add a reference to Neodynamic.CF.Barcode1D.dll assembly
    • In the Form_Load event procedure of the form, write the following sample code which instantiates Barcode1D class and generates a Code 128 barcode image to be displayed in the PictureBox control.
      Visual Basic .NET 
      'Create a Barcode1D object

Dim bc As New Neodynamic.CF.Barcode1D.Barcode1D()
'Set barcode symbology

bc.Symbology = Neodynamic.CF.Barcode1D.Symbology1D.Code128
'Set value to encode

bc.Code = "123456789"
'Set additional text

bc.Text = "Employee ID"
'Set dimensions

bc.BarWidth = 0.01F
bc.BarHeight = 0.5F
'...
'Generate barcode image and display it

Me.pictureBox1.Image = bc.GetBarcodeImage()
      Visual C# .NET 
      //Create a Barcode1D object
Neodynamic.CF.Barcode1D.Barcode1D bc = new Neodynamic.CF.Barcode1D.Barcode1D();
//Set barcode symbology
bc.Symbology = Neodynamic.CF.Barcode1D.Symbology1D.Code128;
//Set value to encode
bc.Code = "123456789";
//Set additional text
bc.Text = "Employee ID";
//Set dimensions
bc.BarWidth = 0.01f;
bc.BarHeight = 0.5f;
//...
//Generate barcode image and display it
this.pictureBox1.Image = bc.GetBarcodeImage();
    • That's it. Build your project and test it. You should get the barcode image displayed in PictureBox control.
  • Displaying 2D barcodes, for example Data Matrix
    • Open Visual Studio Toolbox and drag & drop a PictureBox control and set its SizeMode property to CenterImage
    • Add a reference to Neodynamic.CF.Barcode2D.dll assembly
    • In the Form_Load event procedure of the form, write the following sample code which instantiates Barcode2D class and generates a Data Matrix barcode image to be displayed in the PictureBox control.

'Set additional text

bc.Text = "Card ID"
'Set dimensions

bc.DataMatrixModuleSize = 0.04F

      Visual C# .NET 
      //Create a Barcode2D object
Neodynamic.CF.Barcode2D.Barcode2D bc = new Neodynamic.CF.Barcode2D.Barcode2D();
//Set barcode symbology
bc.Symbology = Neodynamic.CF.Barcode2D.Symbology2D.DataMatrix;
//Set value to encode
