onExecute
int onExecute(int transactionType, Ddeml.HCONV hconv, Ddeml.HSZ topic, Ddeml.HDDEDATA commandString) A client uses the XTYP_EXECUTE transaction to send a command string to the server. A Dynamic Data Exchange (DDE) server callback function, DdeCallback, receives this transaction when a client specifies XTYP_EXECUTE in the DdeClientTransaction function.Remarks
This transaction is filtered if the server application specified the CBF_FAIL_EXECUTES flag in the DdeInitialize function.
Because most client applications expect a server application to perform an XTYP_EXECUTE transaction synchronously, a server should attempt to perform all processing of the XTYP_EXECUTE transaction either from within the DDE callback function or by returning the CBR_BLOCK return code. If the hdata parameter is a command that instructs the server to terminate, the server should do so after processing the XTYP_EXECUTE transaction.
- Parameter:

- uType - The transaction type.hconv

- hsz1 - A handle to the topic name.commandString
- A handle to the command string.- Gibt zurück:
- A server callback function should return DDE_FACK if it processes this transaction, DDE_FBUSY if it is too busy to process this transaction, or DDE_FNOTPROCESSED if it rejects this transaction.
