you must install the Imaging Source driver for both cameras. If you only install the driver for one cameras, windows uses the standard DCam driver for the next camera, even if it is the same model. Windows differs between the cameras using the serial number of the cameras.

In the program we wrote together, we have a initialize method, that recieves the window handle of the window where to display the live video in. Just pass the handel of the second display window to this method.

You have "test.jpg" hardcoded as name in the CListener class. You have the CListener class instantiated twice in an array with. Also you have two grabbers, one for each connected camera. You assgined CListener to grabber 1 and CListener to grabber 2. Now, both grabbers would save their images to one file named "test.jpg", because the CListener object has this name hardcoded and is not able to change it.
You should create a new member in your CListener class, that contains the name of the image to save to (CString type). When you assign the CListener to your grabber, you should assign the image name (test1.jpg and test2.jpg) to the image file name of your CListener class. Then each grabber would save the image in an own file name.

somewhere in your source code (Visiondoc.cpp starting at line 198) there are the listeners assigned to your grabber. There you can also assigne the file names for the images to save.
In you CListener class insert a new public member:
Then you only need to write
m_cListener.m_cFileName = "Test1.jpg"
m_cListener.m_cFileName = "Test2.jpg"
In CListener.cpp you only need to exchange "test.jpg" with m_cFileName.

m_cFileName replace "test.jpg" No work

The "L" in front of the the string, means, that you use wchar (two bytes per character), also named unicode. You have now two way:
- find the Bitmap object in a non unicode library
- change the m_cFileName string to wchar
