Question

What library can you recommend to capture image from a webcam in .Net?

Answer 1

Windows Image Acquisition does the trick with wiaCommandTakePicture (VB.NET as per your tag 🙂 )

as demonstrated in this project by Hanselman in coding4fun

I pasted the C# code, but you can read the VB.NET alternatives on the site also:

CommonDialogClass class1 = new CommonDialogClass(); Device d = class1.ShowSelectDevice(WiaDeviceType.UnspecifiedDeviceType, true,false); if (d != null) {     settings.DeviceID = d.DeviceID;     settings.Save(); }   Item item = device.ExecuteCommand(CommandID.wiaCommandTakePicture); foreach (string format in item.Formats) {     if (format == jpegGuid)     {         WIA.ImageFile imagefile = item.Transfer(format) as WIA.ImageFile;         filename = GetFreeFileName();         if (string.IsNullOrEmpty(filename) == false)         {             imagefile.SaveFile(filename);         }         this.picLastImage.Load(filename);         return filename;     } }
