Data Matrix PCL Code For .NET
Now I am creating Data Matrix in VB.NET. Here is a sample code to have a try:
Dim barcode As DataMatrix = New DataMatrix
' Data Matrix Barcode Basic Settings
barcode.Data = "112233445566"
barcode.DataMode = DataMatrixDataMode.ASCII
'if your selected format mode doesnot have enough space to encode your data,
'the library will choose the right format mode for you automatically.
barcode.FormatMode = DataMatrixFormatMode.Format_48X48
'Set the ProcessTilde property to true, if you want use the tilde character "~"
'to specify special characters in the input data. Default is false.
'1) 1-byte character: ~0dd/~1dd/~2dd (character value from 000 ~ 255);
' ASCII character '~' is presented by ~126;
' Strings from "~256" to "~299" are unused
' modified to FS, GS, RS and US respectively.
'2) 2-byte character (Unicode): ~6ddddd (character value from 00000 ~ 65535)
' Strings from "~665536" to "~699999" are unused
'3) for GS1 AI Code:
' ~ai2: AI with 2 digits
' ~ai3: AI with 3 digits
' ~ai4: AI with 4 digits
' ~ai5: AI with 5 digits
' ~ai6: AI with 6 digits
' ~ai7: AI with 7 digits
'4) ECI: ~7dddddd (valid value of dddddd from 000000 to 999999)
'5) ~rp: Reader Programming (for ASCII mode and Auto mode only)
'6) ~m5: 05 Macro (for ASCII mode and Auto mode only)
'7) ~m6: 06 Macro (for ASCII mode and Auto mode only)
barcode.ProcessTilde = True
' Barcode Size Related Settings
barcode.UOM = UnitOfMeasure.PIXEL
barcode.X = 3
barcode.LeftMargin = 0
barcode.RightMargin = 0
barcode.TopMargin = 0
barcode.BottomMargin = 0
barcode.Resolution = 96
barcode.Rotate = Rotate.Rotate0
' Image format setting
barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Gif()

Thanks for your nice ionfo. But using code to deal with the related problem is too complicated for me. I will try it later.

I was trying to generate data matrix in VB.NET with the code you posted. The images came but the width and height of the barocde remained the same no matter what numbers I put in the source code to replace. Any idea why and how to solve it. Please.
