The NDdeIsValidAppTopicList function is called to check an application and topic string (“AppName|TopicName”) for proper syntax.
BOOL NDdeIsValidAppTopicList(
LPTSTR targetTopic |
// points to app and topic string |
); |
If the targetTopic parameter has valid syntax, the return value is nonzero.
If the function fails, the return value is zero.
This function is also called by NDdeShareAdd when it creates the DDE share.
