    I am trying to save the settings last used on the scanner. I am trying to use the CUSTOMDSDATA api, but am having trouble figuring out what size I should set the InfoData buffer to. I tried calling the MSG_GET function with the length set to zero, hoping that it would return the required size, but that didn’t work.

    Any help at all would be appreciated.

    Thanks

    you don’t set it, the DS sets it – it seems to work for me…
