Windows service cannot open device Printed From: Way2call Communications Category: Hi-Phone Software Development Kit (SDK) Forum Name: Hi-Phone and .NET Forum Description: Discussion on the Hi-Phone product family, its .NET interface, samples and development tools URL: http://www.way2call.com/forum/forum_posts.asp?TID=24 Printed Date: Apr 26 2024 at 11:21am Topic: Windows service cannot open device Posted By: sk Subject: Windows service cannot open device Date Posted: May 15 2009 at 9:56am Using the .NET SDK I am developing a windows service to interact with the desktop pro. When I try to open the device (w2cDrv.Device.Open(0)) after initializing the driver it throws the following exception: "Unable to cast object of type 'WindowsServiceName' to type 'System.ComponentModel.ISynchronizeInvoke. If I transfer the same snippet of code into a Windows forms application there is no problem. Does anyone know what the issue might be, thanks.
