Class does not implement interface member!

[some buddy]

Hi All,

I am trying to implement the following code:

public class SampleFamilyLoadOptions : IFamilyLoadOptions
{
    #region IFamilyLoadOptions Members
 
    public bool OnFamilyFound(bool familyInUse, ref bool overwriteParameterValues)
    {
        if (!familyInUse)
        {
            TaskDialog.Show("SampleFamilyLoadOptions", "The family has not been in use and will keep loading.");
 
            overwriteParameterValues = true;
            return true;
        }
        else
        {
            TaskDialog.Show("SampleFamilyLoadOptions", "The family has been in use but will still be loaded with existing parameters overwritten.");
 
            overwriteParameterValues = true;
            return true;
        }
    }
 
    public bool OnSharedFamilyFound(Family sharedFamily, bool familyInUse, ref FamilySource source, ref bool overwriteParameterValues)
    {
        if (!familyInUse)
        {
            TaskDialog.Show("SampleFamilyLoadOptions", "The shared family has not been in use and will keep loading.");
 
            source = FamilySource.Family;
            overwriteParameterValues = true;
            return true;
        }
        else
        {
            TaskDialog.Show("SampleFamilyLoadOptions", "The shared family has been in use but will still be loaded from the FamilySource with existing parameters overwritten.");
 
            source = FamilySource.Family;
            overwriteParameterValues = true;
            return true;
        }
    }
 
    #endregion
}

then I call it like this:

dbDoc.LoadFamily(file, new SampleFamilyLoadOptions(), out family);

However, when I'm compiling, I got the following error messages:

"Error 1 'FamilyContentExplorer.SampleFamilyLoadOptions' does not implement interface member 'Autodesk.Revit.DB.IFamilyLoadOptions.OnSharedFamilyFound(Autodesk.Revit.DB.Family, bool, out Autodesk.Revit.DB.FamilySource, out bool)'"

"Error 2 'FamilyContentExplorer.SampleFamilyLoadOptions' does not implement interface member 'Autodesk.Revit.DB.IFamilyLoadOptions.OnFamilyFound(bool, out bool)'"

What am I doing wrong?

TIA,

Using the ref modifiers instead of out?

This is supposed to work like this for two reasons:

1) Initially the call was:

dbDoc.LoadFamily(file, out family);

and there was no problem.

The Document.LoadFamily() method has also an overload supposed to accept the three arguments as stated in my initial post.

2) This implementation attempt is the same as suggested on a Revit (and not only) API dedicated blog:

http://spiderinnet.typepad.com/blog/...mentation.html

There, the author suggests the same aproach:

CachedDoc.LoadFamily("c:/temp/fixed.rfa", new SampleFamilyLoadOptions(), out family);

I respected everything, but it's not working

Tanks for trying to help,

Buddy

OK, after searching a little bit more on the subject, finally I saw what you meant!

Actually, when I wanted to contact the author of that blog about the issue, I've seen that it's already answered

The classic mistake, haste makes waste.

Thanks again,

Buddy
