Sets the file and path that contains the regular expression used for the barcode generation. This regular expression is used for the barcode generation if SetBarcodeValueSource is set to BARCODE_PAGE_CONTENT (1).
This regular expression file is used in conjunction with the regular expression format file set by SetBarcodeRegExpFormatFile.
If pValue is NULL or too small, the function returns FALSE, and pSize will contain the number of bytes required for storing the filename.
If the regular expression file is not set or points to a nonexistent file, the whole text of the printed page is used for the barcode generation.
The file must be a UNICODE text file (UTF-16, little-endian with byte-order mark).
For help in using regular expressions, please see the regular expressions page of the RTK manual.
Internally, the printer driver uses the Microsoft TR1 regular expression library with the ECMA grammar. For more information please see the following page: http://msdn.microsoft.com/en-us/library/bb982727.aspx
SetBarcodeRegExpFile (pDevMode As Long, pValue As String) As Boolean
Input value - pDevMode: handle to the BlackIceDEVMODE structure.
Input value – pValue: filename and path of the regular expression file
Return value - TRUE on success, FALSE otherwise.
NOTE: For 32-bit applications, use pDevMode as Integer, instead of Long.
