EosSavePicturesToHost Issue

[stevewong127]

I am trying to implement saving the pictures to some locations in the computer:

camera.TakePicture();
camera.SavePicturesToHost("G:\Test_Canon");

However, there is always a error :

Unhandled Exception: Canon.Eos.framework.EosException: Device Busy.
Failed to set SaveTo Location.

I will appreciate your answer.

Try
camera.SavePicturesToHost("G:\Test_Canon");
camera.TakePicture();

I have no problem saving to my PC.

Hi Esskar,
First, I would like to thank you for putting this code on the net. I'm a fairly new C# developer, and have never before written a program that controls/uses anything outside the computer, so getting this to work is quite exciting for me.
I still don't have quite what I want though. I'm looking for a command-line utility that I can then call using a web interface or whatever (once the basic code is working, I'll be wanting to pass in a couple of params). My code for this is pretty much the same as everyone else's, and I'm having the same problem: I can create my folder, but I cannot save images to it.
Using VS2010, Vista, EOS 50D.
Any suggestions would be hugely appreciated.

                    namespace CanonCameraController {
                        class Program {
                            static void Main(string[] args) {
                                var framework = new EosFramework();
                                var cameras = framework.GetCameraCollection();
                                foreach (var camera in cameras) {
                                    Console.WriteLine("Connected to {0}", camera.DeviceDescription);
                                    try {
                                        string path = Properties.Settings.Default.ImageSavePath;
                                        string fileName = Properties.Settings.Default.ImageName;

                                        DirectoryInfo dir = new DirectoryInfo(path);
                                        if (!dir.Exists)
                                            dir.Create();
                                        camera.SavePicturesToHost(dir.FullName);
                                        camera.TakePicture();
                                    }
                                    catch (EosException eos) {
                                        Console.Error.WriteLine("Last command failed with error {0}, {1}", eos.EosErrorCode, eos);
                                        Console.ReadLine();
                                    }
                                }
                            }
                        }
                    }

Further to the problems that I and some others are having about this, I wonder if the comment below (source: http://tech.groups.yahoo.com/group/CanonSDK/message/1648) is relevant?
Make sure that after the image is downloaded you have call the
EdsDownloadComplete function. Without it the camera is blocked because thinks
that the transfer is not completed.

It is actually with regard to the camera showing "Busy" after trying to save the photo to PC, which is another problem I am having, but is closely enough related that I thought I'd share it.

This problem appears to only manifest itself when creating a command-line app. I have just tried WinForms and WPF apps. Both work.
Interestingly, if I add an Application.Exit() to the end of my Form1.Load event (on load, the photo is taken) then the photo is not saved. It seems that the application is closed before all the events associated with taking a photo have finished. So, to have a commandline app that saves photos to the pc, I'm still stuck.
If anyone has a way to work around this, please let me know.

Is anyone else having problems with this?
Can anyone propose a solution?
