dwRelMode: PropertyReleaseMode

One of the PropertyReleaseMode values. See the Remarks section for more information.

Examples

The following code example shows how to use the CreatePropertyGroup method to create a shared property group manager.

// Create a shared property group.
SharedPropertyGroup^ group =
   groupManager->CreatePropertyGroup( "Receipts",  lockMode,  releaseMode,  groupExists );

// Create a shared property group.
SharedPropertyGroup group = groupManager.CreatePropertyGroup("Receipts",
                           ref lockMode, ref releaseMode, out groupExists);

' Create a shared property group.
Dim group As SharedPropertyGroup = groupManager.CreatePropertyGroup("Receipts", lockMode, releaseMode, groupExists)

Remarks

Using dwIsoMode, during get and set operations, you can either choose to make locking properties atomic by specifying SetGet, or to lock properties over the duration of the method call by specifying Method.

Caution

Do not use Method when creating a property group in a constructor, doing so can result in a deadlock.

If the release mode specified for dwRelMode is Process, the property specified by name is held alive for the lifetime of the process.
