SUMMARY
This article describes how to determine the message store provider name.



MORE INFORMATION
The following code sample illustrates how to retrieve the PR_PROVIDER_DISPLAY property of a given message store. This can be useful in determining the type of information store you are working with.

Here is the code: #include   #include    // NOTE: You will need to include Mapi32.lib as an additional // library in the Link tab of the Project Settings dialog box.

HRESULT MsgStoreType ( LPMAPISESSION pSession, LPSBinary pMsgStoreID ) {     HRESULT         hRes = S_OK; LPMAPITABLE    pTable = NULL; LPSRowSet      pRows = NULL; SRestriction   sRes; SPropValue     spvStoreID;

SizedSPropTagArray ( 2, spta ) = { 2, PR_ENTRYID, PR_PROVIDER_DISPLAY };

ZeroMemory ( &sRes, sizeof ( SRestriction ));

spvStoreID.ulPropTag = PR_ENTRYID; spvStoreID.Value.bin.cb = pMsgStoreID -> cb; spvStoreID.Value.bin.lpb = pMsgStoreID -> lpb;

// Open the message stores table. hRes = pSession -> GetMsgStoresTable ( 0l, &pTable ) ) );

if ( FAILED ( hRes ) ) goto Cleanup;

sRes.rt = RES_PROPERTY; sRes.res.resProperty.relop = RELOP_EQ; sRes.res.resProperty.ulPropTag = PR_ENTRYID; sRes.res.resProperty.lpProp = &spvStoreID;

// Find the row that matches the passed in message store ID. hRes = HrQueryAllRows ( pTable,                           (LPSPropTagArray)&spta,                            &sRes,                            NULL,                            0l,                            &pRows ) ) ) goto Cleanup;

// PR_PROVIDER_DISPLAY is in pRows -> aRow -> lpProps[1].Value.lpszA MessageBox ( m_hWnd,                 pRows -> aRow -> lpProps[1].Value.lpszA,                  "Information Store",                  MB_OK );

Cleanup:

if ( pTable ) {        pTable -> Release ; pTable = NULL; }

if ( pRows ) FreeProws ( pRows );

return hRes; }
