3. Extract the name of each property key by calling the MQPropertiesKeyIterationGetNext() function.

4. Determine the type of the property value for a given key by calling the MQGetPropertyType() function.

5. Use the appropriate MQGet...Property function to find the property value for the specified property key.

   If you know the property key, you can just use the appropriate MQGet...Property function to access its value.
