Indicates whether to display the TWAIN user interface with or without the Scan button, if supported.

HTWAINSESSION hSession

Handle to an existing TWAIN session. This handle is obtained by calling either the L_TwainInitSession or L_TwainInitSession2 function.

Flag that indicates whether to display the user interface.  Possible values are:

Value Meaning
TRUE Display the TWAIN user interface without the scan button, if supported.
FALSE Display the normal TWAIN driver user interface with the scan button. (Default)

Returns

Value Meaning
SUCCESS The function was successful.
! = SUCCESS An error occurred. Refer to Return Codes.

Comments

To display the TWAIN driver user interface without the scan button, call this function with the bEnable parameter set to true. Then call L_TwainTemplateDlg to display the template dialog.

If you call this function with the bEnable parameter set to false, the template dialog will display the normal TWAIN user interface, with the scan button.
