c# - How do I Change comboBox.Text inside a comboBox.SelectedIndexChanged event? -

-

कोड उदाहरण: 

  निजी शून्य comboBox_SelectedIndexChanged (ऑब्जेक्ट प्रेषक, EventArgs ई) {if ( कुछ स्थिति) {comboBox.Text = "new string"}}

मेरी समस्या यह है कि कॉम्बोबॉक्स पाठ हमेशा चयनित इंडेक्स के स्ट्रिंग मान को दिखाता है और नये स्ट्रिंग नहीं। क्या यह एक रास्ता है?

यह कोड काम करना चाहिए ... 

  सार्वजनिक फॉर्म 1 () {InitializeComponent (); ComboBox1.Items.AddRange (नया स्ट्रिंग [] {"आइटम 1", "आइटम 2", "आइटम 3"}); } निजी शून्य comboBox1 से चुने गए इंडेक्स (वस्तु प्रेषक, EventArgs ई) {स्ट्रिंग पाठ = "आपने चुना:" + comboBox1.Text; BeginInvoke (नई एक्शन (() = & gt; comboBox1.Text = text)); }

आशा है कि यह मदद करता है ... :)

SQL/PHP: Table design question -

-
I have two tables, called a "cart" and what I call "items" That the cart be able to store a "item" and a list of quantities. That's why I have created another table "cart_items" which contains the ID of the template, the ID of the item and the quantity. Is this a good design, or should I add another area for the ID of "cart_itim"? Or is there a better way to do it all together? When I try to update my car, I am just running in trouble, my cart items do not update properly, what am I going to do all "cart_times" by car Is connected and then to re-add each "cart_item" and I can not help but it seems that there should be a better way This is a very good design. In the words ER (unit relationship) there are many relationships between objects and cart, through this I mean that an item can appear in many different trains and many different in a cart - Different items may be included In this context ...

NHibernate Passing Session to the Repository -

-
How do I go about passing a session for a repository class? We say that I have two projects 1) TestSite 2) Business Objects The Republican Business Objects Project is included in the project. The NHibernate session has been opened in the test site project. Now, I want to use the same session because the test site initiates the transaction on that session. Currently, I am using the following: var repository = New Customer Resor (_session); Of course, it looks ugly! I'm thinking in some way that a dependency injection frame can be tilted and I can be provided without entering the repository with the ejection object. In our WCF service, we actually use a unitofwork that wraps an operation and stores ISSN for that operation. . The repositories know how they are receiving a hint from the current unit of work under which they are running In case of testing we have a base test class, Those who are included in any test class, who touch the test database, we then control t...

When I wanted to verify my in-memory xml schema, I found this strange error, did I do anything wrong?
