BUG: RasDial() Fails with Error 87 in 16-bit App in Windows 95

• Microsoft Windows Software Development Kit (SDK) 4.0

SYMPTOMS

A function call to the RasDial() API from a 16-bit Windows-based application that is running in Windows 95 fails with error 87 in Windows 95 if the hWndNotifier parameter of the RasDial() API is initialized to a NULL value.

RESOLUTION

An application should always provide a window handle for this parameter even if it will not be processing the messages posted by the RAS DLLs to this window.

MORE INFORMATION

Specifying a NULL value for window handle in the RasDial() API call is common for a Visual Basic application. In such a scenario, the application makes repetitive calls to RasGetConnectStatus() to get the status of the connection. However, calling RasDial() in this fashion causes it to fail on Windows 95 with error 87.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
