Scanner With WIA(Flatbed and )

                                                                WIA (Flatbed and ADF)

Some important point you have to fallow  before to start the development :-

1.  Before to start you should know something about WIA.
2.  Read about Windows image Acquisition properties and feature.
3. You have to import the Interop.WIA.dll

Steps you need to fallow for development :-

1.  Open your visual studio, go to file and create windows form application.
2.  Select language as c#.
3.  Give your application name as you want.
4.  Now go to the solution explorer right click and add form.
5. Take one button control.

Now generate the click event of scan button.

 

Now you have to write the code for calling the scanner properties  initialized  the device and process , so you have to write this code into your form Initialization event.

Most Important point is-  You have to add reference of Interop.WIA.dll

public Form2()

{

      InitializeComponent();

      //Get default device Id 

     _deviceId = FindDefaultDeviceId(); 

     //Find Device 

     _deviceInfo = FindDevice(_deviceId);

     //Connect the device 

     _device = _deviceInfo.Connect();

} 

1. private DeviceInfo FindDevice(string deviceId)  
2.         {  
3.             DeviceManager manager = new DeviceManager();  
4.             foreach (DeviceInfo info in manager.DeviceInfos)  
5.                 if (info.DeviceID == deviceId)  
6.                     return info;  
7.   
8.             return null;  
9.         }  
10.   //finding the device Id here
11.         private string FindDefaultDeviceId()  
12.         {  
13.             string deviceId = Properties.Settings.Default.ScannerDeviceID;  
14.             if (String.IsNullOrEmpty(deviceId))  
15.             {  
16.                 // Select a scanner  
17.                 WIA.CommonDialog wiaDiag = new WIA.CommonDialog();  
18.                 Device d = wiaDiag.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false);  
19.                 if (d != null)  
20.                 {  
21.                     deviceId = d.DeviceID;  
22.                     Properties.Settings.Default.ScannerDeviceID = deviceId;  
23.                     Properties.Settings.Default.Save();  
24.                 }  
25.             }  
26.   
27.             return deviceId;  
28.         }  

 Copy and paste below code

 Note :- Add the final You have to set the properties of device ID, check into below Image

 

 this is the final solution with WIA.

If you have any doubt and problems you can contact with me any time.

all the best.
