VintaSoftTwain ActiveX in laptop with integrated webcam

Hello,

I'm trying to test VintaSoftTwain ActiveX in my laptop (Dell Latitude E6400) with integrated webcam (from Creative Labs) but I'm getting an error (I'm using the javascrip example).

When I click "Get an image with device dialog" or "Get an image without a device dialog" buttons it launches a popup with no sources (to be selected).

In the directory "C:\Windows\twain_32" there is only a file "wiatwain.ds".

Can you give me some help on this ?

In the twain.log I get the following messages:

TWAIN_32.DLL - MESSAGE - CTwunk ::AppInitialize - Reset Log

TWAIN_32.DLL - MESSAGE - CTwunk ::OpenServer - Starting Thunker

TWAIN_32.DLL - MESSAGE - CTwunk ::CloseServer - Why Can't We Find The Thunker Window?

TWAIN_32.DLL - MESSAGE - DSM --DsmEntryDiagExit (RC = 0, CC = 0)

TWAIN_32.DLL - MESSAGE - CTWTRACE--VintaSoftTwain(38) to NULL:

TWAIN_32.DLL - MESSAGE - CTWTRACE--CONTROL, IDENTITY, GETDEFAULT

TWAIN_32.DLL - MESSAGE - DSM --DsmEntryDiagExit (RC = 1, CC = 3)

TWAIN_32.DLL - MESSAGE - CTWTRACE--VintaSoftTwain(38) to NULL:

TWAIN_32.DLL - MESSAGE - CTWTRACE--CONTROL, IDENTITY, USERSELECT

TWAIN_32.DLL - MESSAGE - DSM --DsmEntryDiagExit (RC = 3, CC = 0)

TWAIN_32.DLL - MESSAGE - CTWTRACE--VintaSoftTwain(38) to NULL:

TWAIN_32.DLL - MESSAGE - CTWTRACE--CONTROL, PARENT, CLOSEDSM

TWAIN_32.DLL - MESSAGE - DSM --DsmEntryDiagExit (RC = 0, CC = FFFF)

Thanks in advance.

Best regards,
Ana

Hello Ana,

You have no sources - this means that you do not have TWAIN or WIA drivers installed in the system. Please try to find TWAIN or WIA driver for your webcam.

Best regards, Alexander
