DataMatrix ActiveX 3.5 - User Guide and FAQ

Frequently Asked Questions - DataMatrix ActiveX

1. What image formats can barcode be saved in?
   The barcode controls can save files in the following formats: JPEG, GIF, PNG, TIFF, BMP, WMF, EMF.
   To be able to save images in these formats, you must have the GDI+ library (supplied beginning from Windows XP, 2003 and higher) on your PC. If you do not have this library, you can copy it to the System32 folder from any other PC where it is installed.
   
   
2. Can your DataMatrix-ActiveX controls be used in scripting languages (VB Script, Java Script)?
   Yes, you can use our barcode controls in such scripting languages as VBScript and JavaScript. All properties and methods of our controls are script-compatible. We carried out special compatibility tests for the scripting languages.
   
   
3. Are your controls compatible with .NET, and how should they be used in the .NET environment?
   Yes, the barcode controls are fully compatible with the .NET environment. Most development tools (VB.NET, C#, etc.) allow you to transparently use COM and ActiveX controls. You do not have to do anything special for that.
   
   
4. Is it possible to encode binary data with your DataMatrix barcodes?
   Yes, it is. To encode binary data, you should convert each byte into the following form:
   
   ~xNN
   
   where NN is your binary number.
   Suppose you need to encode the following byte array:
   
   0000C7A9030030323141642343001D2774
   
   You should convert it into the following string:
   
   "~x00~x00~xC7~xA9~x03~x00~x30~x32~x31~x41~x64~x23~x43~x00~x1D~x27~x74"
   
   This string must be attributed to the DataToEncode property. Our DataMatrix will decode this string and your real barcode will have your initial byte array in it instead of the string.
