When running Dynamics NAV as a Remote Application or in Remote Desktop you are missing connection to your locally connected scanner. I have created a solution that uses a standalone application running on the client computer. That application uses the TwainControlX from Ciansoft and connects to a Microsoft SQL database. The database needs to be on a computer that both the client computer and the remote desktop computer have access to.
On that database server a database is created with only one table. That table can be truncated every night in a maintenance job. This is the table creation script.
CREATE TABLE [dbo].[ScanRequests](
[ComputerName] [varchar](20) NOT NULL,
[ClientName] [varchar](20) NOT NULL,
[SelectedDeviceID] [varchar](250) NULL,
[Image] [image] NULL,
[RequestDateTime] [datetime] NULL,
[FormatID] [varchar](50) NULL,
[AnswerDateTime] [datetime] NULL,
[Answered] [int] NOT NULL,
[AnswerText] [varchar](250) NULL,
[PageNo] [int] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
The program on the client then connects to the database and to the scanner.
A code in Dynamics NAV creates the request for a scan by inserting a entry into the ScanRequest table and the application on the client computer automatically scans the images and updates that scan request entry. The updated entry then containes the image file that is imported into Dynamics NAV or attached as a link.
