Dears,

I have a USB Camera connected to my pc.
I want to take pictures and save them.

I tried the following code but i got this error "HRESULT: OX80210015"
on this line
(Device d = class1.ShowSelectDevice(WiaDeviceType.CameraDeviceType,true,false))



using WIA;

string wiaFormatGIF = "{B96B3CB0-0728-11D3-9D7B-0000F81EF32E}";

WIA.CommonDialogClass class1 = new WIA.CommonDialogClass();
Device d = class1.ShowSelectDevice(WiaDeviceType.CameraDeviceType,true,false);
if (d != null)
{
DeviceID = d.DeviceID;
}
else
{
return;
}

WIA.CommonDialog WiaCommonDialog = new CommonDialogClass();

WIA.Item item = d.ExecuteCommand(WIA.CommandID.wiaCommandTakePicture);
ImageFile img = (ImageFile)item.Transfer(wiaFormatGIF);

img.SaveFile("C:\\MyImage.gif");


Any ideas how can i solve this problem?
Thanks in advance.
