Returns the text from the history of the conversation window. Not scriptable.

Syntax

HRESULT History(
   [out,
   retval] BSTR* bstrHistoryText
);

Parameters

bstrHistoryText

Pointer to a BSTR that contains the text of the conversation window.

Return Value

Returns one of the following values. For managed code applications, these return values are received in the form of a COMException.

S_OK

Success.

E_FAIL

The client is not signed in to the primary service at the time this method is called or the conversation window is closed.

S_FALSE

Cannot bring focus to the window.

RPC_X_NULL_REF_POINTER

bstrHistoryText is a null pointer.

Remarks

The history property returns all the contents of the Office Communicator conversation window, including any error messages posted there. This property gives you the capability of archiving IM and conference conversation text. You cannot read this property in your event handler for the DMessengerEvents::OnIMWindowDestroyed event. The conversation history must be accessed to archive before the conversation window is closed.

Example

The example code reads the History property of the IMessengerConversationWnd interface object, imWindow, and displays the returned string on the application console window.

Copy Code
if (imWindow != null)
{
   try
   {
	 Console.WriteLine(imWindow.History);
}
	catch (COMException CE)
	{
		Console.WriteLine("COM Exception " + CE.ErrorCode.ToString());
	 }
}
