I am using WIA to take a photo programatically and this image will then be copied over to a specific folder in my desktop. Everything is going well except for the saving part.
void deviceManager_OnEvent(string EventID, string DeviceID, string ItemID)
{
for (int i = 1; i <= d.Items.Count; i++)
{
wiaImageFile = (WIA.ImageFile)d.Items[i].Transfer(FormatID.wiaFormatJPEG);
wiaImageFile.SaveFile(Properties.Settings.Default.FolderNameRaw + "\\1.jpg");
if (wiaImageFile != null)
Marshal.ReleaseComObject(wiaImageFile);
}
}
In this code, my d.Items.Count is constantly increasing(Eg. 29 which is totally diff from the actual count) even though I only have 2 photos in my camera's SD card. Is there a way to correctly transfer or even cut the file over to my computer?
This is the exception that i receive.
The answer to this is merely choosing the last entry in the index. For my case, I only need to grab the latest photo so this works well.
if (EventID == WIA.EventID.wiaEventDeviceConnected)
{
Console.WriteLine("Connected: D5100");
}
if (EventID == WIA.EventID.wiaEventItemCreated)
{
if (d != null)
{
foreach (Property p in d.Properties)
{
if (p.Name.Equals("Pictures Taken"))
Console.WriteLine("Taken");
}
wiaImageFile = (WIA.ImageFile)(d.Items[d.Items.Count].Transfer(FormatID.wiaFormatJPEG));
wiaImageFile.SaveFile(Properties.Settings.Default.FolderNameRaw + "\\" + imageCount + ".jpg");
imageCount++;
}
}
This works very well. Except that if the file exists already for whatever reasons, you need to do a try catch and fix the problem.
