I need to create an extension to do some custom activity, on File Save Event in visual studio. How to achieve this using VS Package.
I am struck with below code, any advise?
#region Package Members
FileEventsListener listener = null;
protected override void Initialize()
{
Debug.WriteLine (string.Format(CultureInfo.CurrentCulture, "Entering Initialize() of: {0}", this.ToString()));
base.Initialize();
listener = new FileEventsListener();
}
#endregion
}
public class FileEventsListener : IPersistFileFormat, IDisposable
{
private IVsSolution solution;
private uint solutionEventsCookie;
private bool isDirty;
private string fileName;
private const uint MyFormat = 0;
private const string MyExtension = ".edmx";
public FileEventsListener()
{
//solution = Package.GetGlobalService(typeof(SPersistFileFormat)) as IVsSolution;
//if (solution != null)
//{
// solution.AdviseSolutionEvents(this, out solutionEventsCookie);
//}
}
#region IDisposable Members
public void Dispose()
{
}
#endregion
public int GetClassID(out Guid pClassID)
{
ErrorHandler.ThrowOnFailure(((IPersist)this).GetClassID(out pClassID));
return VSConstants.S_OK;
}
public int GetCurFile(out string ppszFilename, out uint pnFormatIndex)
{
pnFormatIndex = MyFormat;
ppszFilename = fileName;
return VSConstants.S_OK;
}
public int GetFormatList(out string ppszFormatList)
{
char Endline = (char)'\n';
string FormatList = string.Format(CultureInfo.InvariantCulture, "My Editor (*{0}){1}*{0}{1}{1}", MyExtension, Endline);
ppszFormatList = FormatList;
return VSConstants.S_OK;
}
public int InitNew(uint nFormatIndex)
{
if (nFormatIndex != MyFormat)
{
return VSConstants.E_INVALIDARG;
}
// until someone change the file, we can consider it not dirty as
// the user would be annoyed if we prompt him to save an empty file
isDirty = false;
return VSConstants.S_OK;
}
public int IsDirty(out int pfIsDirty)
{
pfIsDirty = 0;
return VSConstants.S_OK;
}
public int Load(string pszFilename, uint grfMode, int fReadOnly)
{
fileName = pszFilename;
return VSConstants.S_OK;
}
public int Save(string pszFilename, int fRemember, uint nFormatIndex)
{
return VSConstants.S_OK;
}
public int SaveCompleted(string pszFilename)
{
return VSConstants.S_OK;
}
}
}
