The DdeGetLastError function returns the most recent error code set by the failure of a Dynamic Data Exchange Management Library (DDEML) function and resets the error code to DMLERR_NO_ERROR.
UINT DdeGetLastError(
|
DWORD idInst |
// instance identifier |
|
); |
If the function succeeds, the return value is the last error code. Following are the possible DDEML error codes:
|
Value |
Meaning |
|
DMLERR_ADVACKTIMEOUT |
A request for a synchronous advise transaction has timed out. |
|
DMLERR_BUSY |
The response to the transaction caused the DDE_FBUSY flag to be set. |
|
DMLERR_DATAACKTIMEOUT |
A request for a synchronous data transaction has timed out. |
|
DMLERR_DLL_NOT_INITIALIZED |
A DDEML function was called without first calling the DdeInitialize function, or an invalid instance identifier was passed to a DDEML function. |
|
DMLERR_DLL_USAGE |
An application initialized as APPCLASS_MONITOR has attempted to perform a dynamic data exchange (DDE) transaction, or an application initialized as APPCMD_CLIENTONLY has attempted to perform server transactions. |
|
DMLERR_EXECACKTIMEOUT |
A request for a synchronous execute transaction has timed out. |
|
DMLERR_INVALIDPARAMETER |
A parameter failed to be validated by the DDEML. Some of the possible causes follow: |
|
The application used a data handle initialized with a different item name handle than was required by the transaction. The application used a data handle that was initialized with a different clipboard data format than was required by the transaction. The application used a client-side conversation handle with a server-side function or vice versa. The application used a freed data handle or string handle. More than one instance of the application used the same object. | |
|
DMLERR_LOW_MEMORY |
A DDEML application has created a prolonged race condition (in which the server application outruns the client), causing large amounts of memory to be consumed. |
|
DMLERR_MEMORY_ERROR |
A memory allocation has failed. |
|
DMLERR_NO_CONV_ESTABLISHED |
A client’s attempt to establish a conversation has failed. |
|
DMLERR_NOTPROCESSED |
A transaction has failed. |
|
DMLERR_POKEACKTIMEOUT |
A request for a synchronous poke transaction has timed out. |
|
DMLERR_POSTMSG_FAILED |
An internal call to the PostMessage function has failed. |
|
DMLERR_REENTRANCY |
An application instance with a synchronous transaction already in progress attempted to initiate another synchronous transaction, or the DdeEnableCallback function was called from within a DDEML callback function. |
|
DMLERR_SERVER_DIED |
A server-side transaction was attempted on a conversation terminated by the client, or the server terminated before completing a transaction. |
|
DMLERR_SYS_ERROR |
An internal error has occurred in the DDEML. |
|
DMLERR_UNADVACKTIMEOUT |
A request to end an advise transaction has timed out. |
|
DMLERR_UNFOUND_QUEUE_ID |
An invalid transaction identifier was passed to a DDEML function. Once the application has returned from an XTYP_XACT_COMPLETE callback, the transaction identifier for that callback function is no longer valid. |
