Save data for next session

Hi, i just switched from VC6 to .NET 2 (2005 edition). Besides a lot of other things i have problems to get used to the all new techniques. I want to store a value in a dialog for the next session with my app.
Befor i used WriteProfileInt from the Windows SDK i.e. and in the OnInitDialog i loaded the value with GetProfileInt from the SDK.
What do i have to do in .NET?
I read something about configuration .config XML files etc. but did not find a easy way to store the data when exiting the app.

Please help

As a first simple solution you could use Microsoft::Win32::Registry and Microsoft::Win32::RegistryKey :

It might be an idea to create your own settings class, where each setting is represented externally as a property. Internally it could use the registry but later on could be changed to use XML config files instead.

Hy Zaccheus,
is there an easy example to approach my own settings class?

Here's a simplified version of what I use:

Code:

---


// .h

public ref class ApplicationConfiguration
{
public:
    static System::String^ ReadString
        (
        System::String^ inKeyName,
        System::String^ inValueName,
        System::String^ inDefault
        );
    static void WriteString
        (
        System::String^ inKeyName,
        System::String^ inValueName,
        System::String^ inValue
        );
private:
  /////////////////////////////////////////////////////////////////
  // Choose your own company name and application name.
  /////////////////////////////////////////////////////////////////
    static System::String^ baseName = L"HKEY_CURRENT_USER\\Software\\MYCOMPANYNAME\\MYAPPNAME\\";
};

// .cpp

System::String^ ApplicationConfiguration::ReadString
    (
    System::String^ inKeyName,
    System::String^ inValueName,
    System::String^ inDefault
    )
{
    System::Object^ result = Microsoft::Win32::Registry::GetValue(baseName + inKeyName, inValueName, inDefault);
   
    return dynamic_cast<System::String^>(result);
}

void ApplicationConfiguration::WriteString
    (
    System::String^    inKeyName,
    System::String^    inValueName,
    System::String^    inValue
    )
{
    Microsoft::Win32::Registry::SetValue(baseName + inKeyName, inValueName, inValue, Microsoft::Win32::RegistryValueKind::String);
}

Obviously you would replace MYCOMPANYNAME and MYAPPNAME with something meaningful.

Thanks for that, but this is not exactly, what i am looking for. I dont want a workaround for that, i would like to use the "normal" mechanism.
I have found out something new.
In VS opening a dialog in design mode, an edit box has a property called ApplicationSettings->PropertyBinding, where you can setup application settings. This seems to be the mechanism, that uses these .config xml files for the properties. But this does not work on my system. If i try to add a new setting, i get an error message:
In my german system:
"Im Projekt wurden keine Einstellungsdateien gefunden. Fügen Sie eine Einstellungdatei hinzu, und wiederholen Sie den Vorgang." which says:
There is no settings file in the project. Add one and try again.
In the help it is said, to use the Project-Designer for that, but i have no project designer and the method in the helpfile seems to talk of a different compiler. My VS has no project designer.
Does anybody know this problem?

Ok, I thought you just want a simple replacement for INI files.
:)

I have not yet investigated the technique you are talking about, but it sounds like I should.
:thumb:

Throw on form TextBox, click on it further in a window of properties open ApplicationSettings, and for property Text set create new adjustment. Thus property Text will be connected with My. Settings.
Not having written a uniform line of a code, the data from this text field will be stored in adjustments.

Probably something is done not so?

Hy, i was a little on holiday.
If i try to do so, i get an error message like described above. I do not have a design manager. What is that? There is nothing with that name in my environment. I am using VS 2005 with VC++ 2005. Are you talking about the same version?
Your technique seems to be, what i am searching for, but it does not work on my computer.
