Having trouble with IsolatedStorage persistence in .NET

[mortovski]

Hi there,

I'm working on a Windows application in C# and wanting to persist MDI window states so that when a user opens the application, it looks like it did when they closed it down.

I've been using the IsolatedFileStorage to save a class with the settings in it. I've set breakpoints in the program and watched as the correct values are supposedly 'saved' in the IsolatedFileStorage location. But then when I load them back from the file, some of the values are not coming back correctly from the file.

Any ideas on what I might be missing here? Below is a snippet of some the code...

Thanks,
Pete

private ModuleSettings windowmodulesettings = new ModuleSettings();
[Serializable()]
public class WindowSettings
    {
        public bool Initialized = false;
        public int Top =0;
        public int Left =0;
        public int Height =0;
        public int Width =0;
        public bool Visible = false; 
    }
 
    [Serializable()]
    public class ModuleSettings
    {
        public WindowSettings Window1 = new WindowSettings();
        public WindowSettings Window2 = new WindowSettings();
 
    }
 
private void LoadModuleSettings()
        {
            IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForAssembly();
 
            IsolatedStorageFileStream isfs1 = 
                    new IsolatedStorageFileStream("WindowSettings.xml", 
                    FileMode.Open, FileAccess.Read, isf);
 
            BinaryFormatter BF = new BinaryFormatter();
            windowmodulesettings = (ModuleSettings) BF.Deserialize(isfs1);
            isfs1.Close();
        }
 
void SaveModuleSettings()
        {
                    IsolatedStorageFile isf =
                        IsolatedStorageFile.GetUserStoreForAssembly();
 
                    IsolatedStorageFileStream isfs1 = 
                        new IsolatedStorageFileStream("WindowModuleSettings.xml",
                        FileMode.Create, FileAccess.Write, isf);
 
                    BinaryFormatter BF = new BinaryFormatter();
                    BF.Serialize(isfs1,windowmodulesettings);
                    isfs1.Close();
        }

Oops - the two filenames above are not the same - I changed the filename for the purpose of posting this question. However, they are the same in the actual file I'm using... sorry....

Got it working now... the trouble wasn't with IsolatedStorage - rather it was that the SaveModuleSettings function was being called multiple times....
