IMAPISession::GetMsgStoresTable

4/8/2010

The GetMsgStoresTable method provides access to the message store table, which contains information about all of the message stores in the session profile.

Syntax

HRESULT GetMsgStoresTable (
  ULONG ulFlags,
  LPMAPITABLE FAR * lppTable
);

Parameters

• ulFlags
  [in] Ignored.

• lppTable
  [out] Reference to the message store table, implemented on IMAPITable.

Return Value

This method returns the standard values E_INVALIDARG, E_OUTOFMEMORY, E_UNEXPECTED, and E_FAIL, as well as the following:

• S_OK
  Indicates success.

Remarks

GetMsgStoresTable retrieves a pointer to the message store table, a table maintained by MAPI that contains information about each open message store in the profile.

The following IMAPITable methods are supported for message store tables in Windows Mobile Messaging:

• IMAPITable::QueryRows
• IMAPITable::SetColumns

Because MAPI updates the message store table during the session whenever changes occur, call the IMAPISession::Advise method to register to be notified of these changes. Possible changes include the addition of new message stores, removal of existing stores, and changes to the default store.

For an example of how to use this method, see the Sending a Message code sample.

Code Example

The following code example demonstrates how to use GetMsgStoresTable.

Note

To make the following code example easier to read, security checking and error handling are not included. This code example should not be used in a release configuration unless it has been modified to include them.

        if (1 != psrs->cRows)
            break;

        // Make sure to get all the properties that you need.
        if ((1 > psrs->aRow[0].cValues)||(PR_ENTRYID != psrs->aRow[0].lpProps[0].ulPropTag))

        // Create a message.
        hr = pfldrDrafts->CreateMessage(NULL, 0, &pmsg);

        // Send the message.
        hr = pmsg->SubmitMessage(0);

        // Free resources.
        MAPIFreeBuffer(rgprops);
        MAPIFreeBuffer(rgpropsMsg);

        RELEASE_OBJ(pmsg);
        RELEASE_OBJ(pfldrDrafts);
        RELEASE_OBJ(pStore);
    }

FuncExit:

    //Clean up
    MAPIFreeBuffer(rgprops);
    MAPIFreeBuffer(rgpropsMsg);

    FreeProws(psrs);

    RELEASE_OBJ(pmsg);
