i'm trying to read datamatrix and code128 simultaneously with one call like this:

rc = L_BarCodeRead(bitmapHandle,
roi,
BARCODE_DM_READ_RECTANGLE | BARCODE_DM_READ_SMALL | BARCODE_DM_READ_SQUARE | BARCODE_1D_CODE_128,
BARCODE_SCANLINES_PER_PIXELS,
0, //default, no special flags
10,
&BarCode1D,
NULL,
NULL, //&BarColor,
&pBarCodeData,
sizeof(BARCODEDATA));

However, I'm only getting the code128 barcode recognized. If I leave
out the BARCODE_1D_CODE_128, the datamatrix barcodes are recognized.

Is it possible to recognize simultaneously, if so, what's the best way?

greets
matthias

Matthias,

The documentation for the ulSearchType parameter of L_BarCodeRead function states that you "... can combine values when appropriate among the same group values..."
This means you cannot OR search types from different groups such as 1D and datamatrix.

Thanks,
