we use an scanner from Brother and have the problem, that always the Dialog from the Scanner is shown. In the params we define that we don't want the dialog to be shown.
We are in contact with the brother dealers suppport. They tested against the Imageen Demos.
Here is the feedback from brother.
The following point described in “State 4 to 5 - Request the Acquisition of Data from the Source” causes this problem.
TW_BOOL Show UI; TW_BOOL ModalUI;
If you want to display the UI, ShowUI = TRUE (Numerically1) ModalUI = TRUE (Numerically 1)
If you want to hide the UI, ShowUI = FALSE (Numerically 0) ModalUI = FALSE (Numerically 0)
This issue will be solved if the above points in the application is revised. It seems that -1 is now specified in both cases.
