Submits a simple request to the Provisioning Queue Manager Service of Microsoft. Provisioning Framework (MPF).

SubmitRequest includes an option to submit a suspended request. SubmitRequest is the standard method to submit untrusted requests to queue managers for both COM and HTTP/SOAP applications.


HRESULT SubmitRequest  (
	BSTR bstrRequest,
	BSTR bstrNamespace,
	BSTR bstrProcedure,
	BOOL fSuspended,
	BSTR *bstrQueueID
Visual Basic
Function SubmitRequest ( _
	bstrRequest As String,   _
	bstrNamespace As String, _
	bstrProcedure As String, _
	fSuspended As Boolean	_
) As String


XML data node for the request.
Name of the namespace for the procedure invoked by the request. 
Name of the procedure invoked by the request. 
Specifies whether the request is submitted as suspended. If set to 1 (true), the queue manager will not execute the request until you unsuspend it with a call to Activate. You can only add a child request to a parent request with IProvQueue::AddDependency if both requests are suspended.
bstrQueueID (C++) / return value (VB)
Queue ID returned for the submitted request. The queue ID returned can be used by Activate, AddDependencyDelete, QueryResults, and QueryStatus.

Return Codes

Zero indicates success; a non-zero value represents an error. For a list of error codes, see MPF Errors.

Performance Counters

Counter Object: Microsoft Provisioning Client
Counter Instance: Queued Requests

Average Request Latency Average time for this client to execute a provisioning request. Each call to SubmitRequest contributes to the average latency of up to the last 100 requests.
Request Rate Incoming request rate for this client. Each call to SubmitRequest contributes to the average request rate of transactions per second.
Requests Executing Number of concurrently executing requests at this client. Identifies the total number of concurrent calls to SubmitRequest.
Total Requests Number of requests this client has processed. Each call to SubmitRequest increments this counter.
Total Requests Failed Total number of failed requests that this client initiated. Each call to SubmitRequest that returns a failed HRESULT increments this counter.


Queued requests can be submitted as either activated or suspended. An activated request is always executed regardless of whether the corresponding MPF transaction succeeds or fails. A suspended request is automatically activated if the transaction succeeds; otherwise the transaction fails and is deleted. It is not possible to suspend an active request.

C++ Example

LPCWSTR wszRequest = L"<request>\n" + 
					 L"  <data>\n" +
					 L"	<organizations>\n" +
					 L"	<organization name=\"tailspintoys.com\"/>\n" +
					 L"	</organizations>\n" +
					 L"  </data>\n" +
					 L"  <context>\n" +
					 L"	<clientContext clientTransactionId=\"53367B03-63D3-44ae-B8AD-C1E57E876E6C\"/>\n" +
					 L"  </context>\n" +

IProvQueue * pProvQueue = NULL;
BSTR bstrRequest = ::SysAllocString(wszRequest);
BSTR bstrNamespace = ::SysAllocString(L"Test Namespace");
BSTR bstrProcedure = ::SysAllocString(L"Write Request");
BSTR bstrQueueID = NULL;

if(bstrRequest && bstrNamespace && bstrProcedure)
	// Create queue manager client:
	hr = CoCreateInstance(CLSID_ProvQueueClient, NULL, CLSCTX_ALL, IID_IProvQueue, (void**)(&pProvQueue));
	if(hr == S_OK)
		hr = pProvQueue->SubmitRequest(bstrRequest, bstrNamespace, bstrProcedure, FALSE, &bstrQueueID);

// Get the error description in the case of error
	IErrorInfo* pErrInfo = NULL;
	if(::GetErrorInfo(0, &pErrInfo) == S_OK && pErrInfo)

// Show the results
MessageBoxW(NULL, bstrQueueID ? bstrQueueID : L"Unknown error occured", L"Queued request results", MB_OK);

// Clean up
