Windows: How do I get list of Data source and their identity

[shlooks]

Hello,

Trying to eliminate the need for manual source selection in NAPS2(http://sourceforge.net/projects/naps2/). In order to achieve that, I thought it must be easy to somehow get list of all current DS and their identity, and then use it in the profile(Identity stored on XML).

Any idea how to do it ? (Any language)

Thanks

Found this in Python: (If anyone will ever need it)

from twain import *

from struct import *

SM = SourceManager(0L)

Identity = pack("156s", "")

firstResult = SM.DSM_Entry(DG_CONTROL, DAT_IDENTITY, MSG_GETFIRST, Identity)

print "Result code: ", firstResult

ProductName = Identity[122:]

iOffset = ProductName.find('')

if iOffset != -1:

ProductName = ProductName[:iOffset]

print "The data source name is: ", ProductName

while SM.DSM_Entry(DG_CONTROL, DAT_IDENTITY, MSG_GETNEXT, Identity) == 0:

ProductName = Identity[122:]

iOffset = ProductName.find('')

if iOffset != -1:

ProductName = ProductName[:iOffset]

print "The data source name is: ", ProductName





firstResult = SM.DSM_Entry(DG_CONTROL, DAT_IDENTITY, MSG_GETDEFAULT, Identity)

print "Result code: ", firstResult

ProductName = Identity[122:]

iOffset = ProductName.find('')

if iOffset != -1:

ProductName = ProductName[:iOffset]

print "The default data source name is: ", ProductName

print ProductName
