Frees the memory specified by the lParam parameter of a posted Dynamic Data Exchange (DDE) message. An application receiving a posted DDE message should call this function after it has used the UnpackDDElParam function to unpack the lParam value.
Enables a Dynamic Data Exchange (DDE) server application to impersonate a DDE client application's security context. This protects secure server data from unauthorized DDE clients.
Enables an application to reuse a packed Dynamic Data Exchange (DDE) lParam parameter, rather than allocating a new packed lParam. Using this function reduces reallocations for applications that pass packed DDE messages.
Contains flags that specify how a DDE server application should send data to a client application during an advise loop. A client passes a handle to a DDEADVISE structure to a server as part of a WM_DDE_ADVISE message.
This learning path introduces Data Analysis Expressions (DAX) and provides you with foundational skills required to enhance semantic models with calculations. It starts by describing Power BI Desktop model structure and how it can be enhanced with DAX calculations. It then describes how you can write DAX formulas and the different types of model calculations, including calculated tables and columns, and measures. Evaluation contexts are introduced, and subsequent lessons describe how to write DAX formulas t
