Cash Drawer - Method Open threw an exception - Windows Service

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :.NET Framework
Hi All, I'm getting the following exception while calling Open method of Cash Drawer object. Method Open threw an exception.  Could not read the device name key's default value, or could not convert the Programmatic ID it holds into a valid Class ID. Code:   class Class1 { CashDrawer _uniCashDrawer1 = null; DeviceInfo cashDrawerDevice1 = null; PosExplorer posExplorer = new Microsoft.PointOfService.PosExplorer();   public void ClaimCashDrawer() { cashDrawerDevice1 = posExplorer.GetDevice("CashDrawer", "testDrawer"); if (cashDrawerDevice1 != null) { _uniCashDrawer1 = posExplorer.CreateInstance(cashDrawerDevice1) as CashDrawer; if (_uniCashDrawer1 != null) { _uniCashDrawer1.StatusUpdateEvent += new StatusUpdateEventHandler(UniCashDrawer1_StatusUpdateEvent); _uniCashDrawer1.Open(); _uniCashDrawer1.Claim(0); _uniCashDrawer1.DeviceEnabled = true; } } } }   Tha above code works fine if you put the code in WindowsApplication in all POS systems. The same is working if you put the code in Windows Service in all other POS systems. The same is not working if you put the code in Windows Service in Aures Galeo POS systems.  Thanks in advance.

Weird Exception: Method not found: 'Double System.Windows.Controls.ScrollViewer.get_ContentHorizon

Hi guys I have an XBAP application that uses a Xamdatagrid from Infragistics. I have some filtering on this grid, that rebinds after a filter. The problem is, when a user has scrolled to a certain point and then filters, the rebinding causes the grid to scroll to the beginning position of the grid. Now how I solve this is by getting an instance of the ScrollViewer, I get the ScrollViewer.ContentHorizontalOffset and then I do a ScrollViewer.ScrollToHorizontalOffset after it filters.   Now here comes the problem. For 99% of the users of this xbap app, this will work absolutely fine. Most, if not all of the users run exactly the same machines, XP 64 bit with 8GB RAM. The other 1% get the error: Method not found: 'Double System.Windows.Controls.ScrollViewer.get_ContentHorizontalOffset()'. I cannot reproduce this error on my own box, our dev server or our production server, it is a phantom exception that only pops up on a certain condition. I have even wrapped the "offending" code in a try catch and it still doesn't solve it. If I set the DispatcherUnhandledExceptionArgs Handled to true, it works, but it doesn't feel right. How is this possible? If the method doesn't exist, how can it compile? Why does that method exist for 99% of the other users running the exact same machines? I have googled my fingers raw without any valid results and this issue is frustrat

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

Windows Services: New Base Classes in .NET Make Writing a Windows Service Easy


Windows services are applications that run outside of any particular user context in Windows NT, Windows 2000, or Windows XP. The creation of services used to require expert coding skills and generally required C or C++. Visual Studio .NET now makes it easy for you to create a Windows service, whether you're writing code in C++, C#, or Visual Basic. You can also write a Windows service in any other language that targets the common language runtime. This article walks you through the creation of a useful Windows service, then demonstrates how to install, test, and debug the service.

Windows 2000: Asynchronous Method Calls Eliminate the Wait for COM Clients and Servers


Windows 2000 is the first version of COM to support asynchronous method calls, which permit clients to make nonblocking calls to COM objects and objects to process incoming calls without blocking the calling threads. COM clients benefit from asynchronous method calls because they can continue working while waiting for outbound calls to return. Objects benefit because they can queue incoming calls and service them from a thread pool. Our SieveClient and SieveServer sample apps demonstrate how to create and use asynchronous clients and servers in COM-based distributed applications.

Open With Windows Explorer very slow


I am trying to troubleshoot an issue where some users of our SharePoint environment have problems using the open with windows explorer option in a document library.


For some users this works fine...  the explorer opens quickly and they can manage the documents.


For other users it takes up to 5 minutes before the explorer view opens.  During this time the browser becomes completly unresponsive.


As part of the troubleshooting process I tried taking the UNC path that is shown in the explorer view and tried using the Start -> Run and then entering in the path.   This seems to cause the complete desktop to freeze until the explorer window displays.


This is occuring on Windows XP SP Pro SP2 with both IE6 and IE7.   The desktops are on the same domain as the SharePoint servers.


Any thoughts on next steps?

Wickedly Strange .Net WPF Performance Problem Dissapeers with Windows 7 Performance Monitor Open

Hello Everyone, I have been developing one large and complex WPF application for 13 months now, all is going well and especially tonight as I now have some sort of clue or hint to what I have been seing now for quite some time.  Here is the rundown. 1) Running on i5 processor with 4GB RAM and Windows 7 2) The application was developed all in .Net 4.0, WPF C#. 3) It is heavily GUI intensive and also uses Entity Framework Detached for Database Access. 4) Is multi-threaded / multi-tasking. I am a nutcase when it comes to testing.  Since my graphical application heavily depends upon performance and determinsm (please somebody don't start with the C++ vs .Net on here) and has been performing great FOR THE MOST PART.  Every once in a while, I see that the application runs into the weeds for 5 or 6 seconds and the interface is unresponsive.  I have this thing tuned finely too.  Well now toward the end of development I have finally had to face that bug so to speak.  I can force it by clicking spastically on my buttons causing an event storm and making the system update the GUI.  SO!  Great start, I can now cause the problem on a regular basis (for you youngsters that is actually a good thing)!  Alright, so I start with the easiest investigative tool, CNTRL - ALT - DEL into Windows 7 Performance Monitor.  As you can tell from

Getting AppDomain.UnhandledException event to work in a Windows Service

Nearly every forum thread I have found on "catching unhandled exceptions in a service" seems to end up where I am.  The supposed solution is the use of the AppDomain.CurrentDomain.UnhandledException event.  But it doesn't work for someone, who then asks why and gets no answer.  Same for me; I can't get the event to happen.  It's as if I need the ServiceProcess version of Application.SetUnhandledExceptionMode(), which doesn't exist. For diagnosing this, I start a timer in a child object of the service and then throw an exception in the timer event handler.  Simple enough to simulate the real situation.  I have tried subscribing to the UnhandledException event in at least a half dozen locations throughout the service, from the Program that runs ServiceBase.Run() to the constructor of the object that owns the Timer, but it never catches this exception. The VS debugger recognizes that the forced exception is unhandled and takes me to the place where is thrown, letting me know it is an unhandled exception. Why doesn't my handler catch it?  Running without the debugger, the exception throws, the timer thread crashes, the service continues merrily along, and nothing gets logged anywhere.  That is NOT the result I need.  What are the people for whom this works doing that I am not doing? How can I at least get the offe

Windows Identity Foundation Security Token Service can't stay logged in

I'm using the Windows Identity Foundation **(WIF)** Security Token Service **(STS)** to handle authentication for my application which is working all well and good. However I can't seem to get any long running login with the STS. From my understanding I shouldn't care about the client tokens at the application level since they can expire all they want to and it should redirect me to the STS and as long as they're still logged in on the STS it should refresh their application token. Yet it doesn't seem to want to keep them signed in. Here's what occurs in my login.aspx on the STS var cookie = FormsAuthentication.GetAuthCookie(userName, persistTicket); if (persistTicket) cookie.Expires = DateTime.Now.AddDays(14); Response.Cookies.Add(cookie); var returnUrl = Request.QueryString["ReturnUrl"]; Response.Redirect(returnUrl ?? "default.aspx"); Which was taken almost directly from existing application using normal Forms Auth. From my web.config <authentication mode="Forms"> <forms loginUrl="Login.aspx" protection="All" timeout="2880" name=".STS" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false" /> </auth

The formatter threw an exception while trying to deserialize the message

Hi I got this error when programming in C# 2008 The formatter threw an exception when trying to deserialize the message: Error while trying to deserialize parameter http://tempuri.org/:GetListSitesResponse. The InnerException message was' Error on line 1, position 314. The item 'http://tempuri.org/:anyType' contains data data contract 'http://tempuri.org/:Site'. The deserializer has no knowledge of any type that is assigned to this contract. Add the type corresponding to 'Site' to the list of known types (eg, using the attribute KnownTypeAttribute or adding it to the list of known types passed to DataContractSerializer). '. See InnerException for more information.
