  [out, retval] LONG *plLeft
);

Property value

Error codes

Returns one of the following values.

Name	Meaning
S_OK	Success.
RPC_X_NULL_REF_POINTER	plLeft is a NULL pointer.
E_FAIL	Could not get window handle.
E_NOTIMPL	Cannot be accessed through scripting.

Remarks

The following table lists error codes returned by this method.

Error Code	Meaning
0x80004001	Cannot be accessed through scripting.
0x80004005	Messenger application window or conversation window has been closed either through user action or the method that launched the window.

If the Messenger window is minimized, the value retrieved will appear to be out of range (>= -32000). If the Messenger window is closed through application programming interface (API) or user action, this method fails to get a value.

If this method called on the IMessengerWindow object of the parent application's Messenger window, it returns the left screen position value of the parent application window.

There is no bounds-checking on input values for lLeft. Negative integer values are accepted, but the window will go no further off the left side than half its width.

Note

This property is not available for scripting languages.

Examples

The following Visual Basic example shows the use of this method.

Public WithEvents MsgrUIA As MessengerAPI.Messenger
Public MsgrWindow As MessengerAPI.IMessengerWindow

Private Sub Form_Load()
    Text_Top.Text = CStr(MsgrWindow.Top)
    Text_Height.Text = CStr(MsgrWindow.Height)
    Text_Left.Text = CStr(MsgrWindow.Left)
    Text_Width.Text = CStr(MsgrWindow.Width)
End Sub
