• SQL Server How can we verify the Clustering algorithm models?

  Hi, all here, Since we are not able to use accuracy chart for Clustering algorithms there. So how can we verify the accuracy of clustering algorithm models here in terms of its classification and regression tasks Thank you very much in advance for your guidance and advices for that. With best regards, Yours sincerely, Of course, the strength of clustering is to find intrinsic categories in your data to allow you understand your data better. You can use Cluster Diagram, cluster profiles, cluster characteristics and Cluster discrimination to explore your data. As a domain expert, this tools should also help you validate the quality of the resulting clusters. We have different clustering algorithms, such as: K-Mean ...Show All

• Smart Device Development Bluetooth device search

  Hello! I have one problem: I wrote an application that recieves some information via Bluetooth. I use SerialPort profile to connect to the device. It worked at Qtek 8300 and O2 Atom.

• Visual C# constructor exceptions for objects in using list lead to problems

  using ( TSomething s1 = new TSomething(1), s2 = new TSomething(2) ) { ...} if during creation of object s2 an exception should occur s1 will be taken care for by "using" (call to dispose) s2 will NOT be taken care of by using (no call to dispose) s2 intended object will be lined up for finalization (sometime) In other languages when a contructor fails the destructor will be autom. called. Here the destructor call is delayed. This leads to problems because it is recommended that constructor throw exceptions (when necessary of course) if constructor does it would have to free special resources (that it planed to do via Dispose / or destructor), something that would normally be reserved for Dispose & ...Show All

• Software Development for Windows Vista XPS and Javascript

  Is there a way to control viewing XPS files in IE7 using javascript Is there a way to start viewing a specific page using the command line when using the document viewer This feature is there in adobe reader and is very important for developers that are developing applications in other languages that .NET like C/C++/Java Thanks for your help. Abdullah Hej CTA, ofcourse I'm not 100% sure if it's the same DocumentViewer control (guess it's derrived from maybe) but according to Tim Sellers, MSFT it's built on the WPF-API, so why should they reinvent the wheel but you'll never know...

• SQL Server Changing connection string dynamically and Reports calling performance

  Hi all, We've a web application (asp .NET) used by a different users mapped to different databases, and a single Server for reporting. We've define reports shared by all users because all databases schemas are same, and it reports deployment is not complicated. When the report is called, it’s queued in a separated thread, and we change the connectionstring of the shared report by SetDataSourceContents before calling the report service (using ReportingService. Render method) . Recently, we have a new problematic. We have implements a new web page that integrate the report result and it work fine. But the problem is that we have to queue all requests and the waiting time can be very important if a lot of request are queued .... I ...Show All

• Audio and Video Development Programatically setting the default playback device (and recording device)

  Under Vista is there a way to set the default playback device programatically I've searched through the APIs but I'm not seeing it. For example, there is a method IMMDeviceEnumerator::GetDefaultAudioEndpoint(), but there is no corresponding IMMDeviceEnumerator::SetDefaultAudioEndpoint(). Can I do this through the endpoint properties Thanks, that's a helpful suggestion (although in our case, it would require a substantial rewrite of our control panel, so this might be more of a long-term solution). Some of the most useful features of our control panel can't be implemented this way, though. We have a "preset" feature where a user can create named sets of all of their audio settings and easily switc ...Show All
