Remarks

The set of command types defined by this class are not intended to be a complete list but rather a simple means for identifying base types likely to be supported by many DDEX providers. For future additions, the numbers 1-99 are reserved for values in this enumeration. Numbers 100+ can be used for provider-specific command types.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
