DdeReconnect

The DdeReconnect function allows a client Dynamic Data Exchange Management Library (DDEML) application to attempt to reestablish a conversation with a service that has terminated a conversation with the client. When the conversation is reestablished, the DDEML attempts to reestablish any preexisting advise loops.

HCONV DdeReconnect(
  HCONV hConv   // handle to conversation to reestablish
);
 

Parameters

hConv

Handle to the conversation to be reestablished. A client must have obtained the conversation handle by a previous call to the DdeConnect function or from an XTYP_DISCONNECT transaction.

Return Values

If the function succeeds, the return value is the handle to the reestablished conversation.

If the function fails, the return value is 0L.

Errors

The DdeGetLastError function can be used to get the error code, which may be one of the following values:

DMLERR_DLL_NOT_INITIALIZED
DMLERR_INVALIDPARAMETER
DMLERR_NO_CONV_ESTABLISHED
DMLERR_NO_ERROR
