Article
08/28/2006

The Logon method logs on the user to a POOM Session. It must be the first method called for a POOM object.

Syntax

HRESULT Logon(
  long hWnd
);

Parameters

hWnd
[in] Handle to the parent window for the POOM session. Outlook Mobile uses this handle for each PIM item's Display call, and for the infrared transfer dialog.

For Visual Basic, this parameter is optional and has a Null default value.

Return Values

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

S_FALSE
The user is already logged on.
S_OK
The method completed successfully.

Code Example

The following code example shows how to log the user on to a POOM session.

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.

HRESULT hr;
IPOutlookApp * polApp;

// Initialize COM for Pocket Outlook.
if (FAILED(CoInitializeEx(NULL, 0))) return FALSE;

// Get the application object.
hr = CoCreateInstance(CLSID_Application, 
                      NULL, 
                      CLSCTX_INPROC_SERVER,
                      IID_IPOutlookApp, 
                      (LPVOID*)&polApp);
if (FAILED(hr)) return FALSE;

// Log on to Pocket Outlook.
hr = polApp->Logon(NULL);
if (FAILED(hr))
    return FALSE;

Remarks

LogOn must be called from a thread that will process Windows messages.

Messages broadcast using SendMessage might hang on the POOM application window. To be safe, use PostMessage instead.

The parent window for the POOM session is the window that recieves Outlook Mobile notification messages. For more information, see Notification Window Messages.
