.net - Using TransactionScope with typed dataset -

-

मेरे पास एक WinForm अनुप्रयोग है जिसमें टाइप-डाटासेट टेडेडएप्टर्स का उपयोग करते हुए SQL डेटाबेस डेटाबेस पूछता है। मेरे पास एक मुख्य फॉर्म असेंबली और एक डेटाबेस असेंबली है जो हर डीबी ऑपरेशन को संभालता है। मुझे लेन-देन में टेबल एडैप्टर का उपयोग करने में समस्या हो रही है और मुझे इसकी सराहना होगी अगर कोई मुझे कोई विचार क्यों दे सकता है

अपडेट () विधि इस त्रुटि को देता है: 

  "कनेक्शन ऑब्जेक्ट लेनदेन क्षेत्र में भर्ती नहीं किया जा सकता है।"

यहां मेरा कोड है: 

  नामस्थान मुख्य {सार्वजनिक वर्ग} मुख्यफ़ॉर्म {निजी MyDbAssembly.MyDbClass db; // इंस्टेंटिएट और डीबी भरने के तरीकों को छोड़ा गया .. निजी शून्य हटाना () ({TransactionScope trans = new TransactionScope ()) {this.db.Delete (id); UpdateDb (); trans.Complete (); }} निजी शून्य UpdateDb () {// बाइंड्सओवर एंडीट एंड amp; Datagridview समाप्त विधियों को छोड़ दिया .. this.db.Update (); }}} नाम स्थान MyDbAssembly {सार्वजनिक वर्ग MyDbClass {निजी myTypedDataset myDataSet; निजी myTypedDataSetTableAdapter.MyTable1Adapter table1Adapter; // मौलिक तरीकों को छोड़ दिया .. सार्वजनिक शून्य हटाएं (गद्य आईडी) {this.myDataSet.MyTable1.FindByID (id) .Delete (); } सार्वजनिक शून्य अद्यतन () {this.table1Adapter.Update (myDataSet.MyTable); // & lt; - ERROR LINE}}

क्योंकि आपने टेबल 1 एडेप्टर को बाहर बनाया है ट्रांजैक्शन स्कोप ट्रांस स्कोप।

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
