Barcode Forums by Morovia

Dear all hi,

i'm new here and i hope i can find some answers here

i'm using morovia 2d datamatrix barcode and i'm using the included dll file to encode the string by my vb.net application

when make a setup project i always get an error at the definition line which is

Dim ecoder As New MrvDMFEAX3Lib.DataMatrixFontEncoderClass

please help

The datamatrix encoder is a COM object. Before you use it you need to register it:

Regsvr32 MrvDMFEAX3.dll

please tell me how to register the com object

In order to register the COM object you need to click on Start menu select Run and type: Regsvr32 MrvDMFEAX3.dll

If MrvDMFEAX3.dll is not in your System32 folder then you need to specify the full path to that dll.

Hope this helps.

still not working

same nothing happen and I change the definition a little hoping from it to work and i got a new error message

Cannot Create ActiveX component.

pleaseeeeeeeeeeeeeee help

i copied the file in the windows\system32 folder and it works okey now

but i got a different error now

in the next form in the roll after I encode the string with the provided dll from morovia, i store all the data in a XML file then i read this file into a crystal report but when this form (containing the crystal report) start to load an error accure says:
