  when a new record is inserted in to table, i want to increment the variable called counter by 1 how can i implement this what is the IDENTITY field in a table is it something like a counter variable pls let me know An identity column can increase by 1 everytime you add a new record.

But identity fields are commonly used for primary keys. I think that is what you wanted to know. If not please explain what you are going to use it for. ...Show All

• Visual Studio Team System Import Database Schema Keys not imported as expected

  Greetings, When I use Import Database Schema on an SQLServer 2000 database project (from an SQL Server 2000 database server) none of the keys, constraints or indexes are imported against the tables. They all appear to be there but are created as objects at the same level as the tables (i.e. under the Tables folder in the tree view) instead of in the appropriately named folders under each table. Everything looks good in Query Analyzer and even if I target SQL Server 2005 the import is the same. All these objects have a red exclamation mark but no errors appear in the error list. Also all my stored procedures and user functions ha ...Show All

• .NET Development .NET remoting with dual lans

  I have 2 computers on 2 separate LANs. Computer A is at 192.1.0.1 on LAN A and 192.1.1.1 on LAN B. Computer B is at 192.1.0.2 on LAN A and 192.1.1.2 on LAN B. I am using a TCPChannel (actually TCPServerChannel/TCPClientChannel) for the connection. Computer A runs a windows service which provides an activation point for a CAO. Computer B will run a client application which activates the CAO. When I run the client application on computer B I can specify the server I want to connect to by IP address thereby being specific about which LAN I want the .NET remoting traffic to use. This is passed to the Activator.CreateInstance method usin ...Show All

• Windows Forms Z-order and losing focus on MdiChildren

  I'm writing a little index cards application. I have a toolbar which has forward and back buttons, for iterating through the collection of cards. When I click the forward button, I move the active MdiChild to the back of the z-order with a SendToBack. However, after that the topmost MdiChild doesn't gain focus and I have to click on it first before being able to proceed forward again. Is there a way to give the top-most MdiChild in the z-order focus programmatically I've tried MouseEventArgs and OnMouseClick to no effect. There are a couple of ways to do this- One is to send CTRL-Tab to the active child window using SendKeys: SendKey ...Show All

• SQL Server SSIS Send Mail task problem

  Hi, I have got the problem connected with Send Mail Task in SSIS. The general idea was: sending email alert to different email users.

• Visual Studio 2008 (Pre-release) Why text editor classes is so closed in Avalon?

  For example, i need insert (by code) a link into RichTextBox. This mean that i need split Run before insertion. Type type = typeof (Control).Assembly.GetType("System.Windows.Documents.TextRangeEdit"); MethodInfo m = type.GetMethod("SplitFormattingElements", BindingFlags.Static | BindingFlags.NonPublic); TextPointer position = m.Invoke( null , new object [] { editor.CaretPosition, true }) as TextPointer; position.InsertTextElement(hyperlink);   Or i need select (by code) text in RichTextBox from 5 to 11 symbol and do something.

• Windows Forms 121 PictureBoxes slow my app. Help me optimize?

  I'm developing a program that uses 121 pictureboxes on one form and when I run the program, it is rather slow.  I haven't even coded yet!  If I try to move the window, the contents get especially choppy.  It's even worse if I'm moving the app and it hits the edge of the screen.  Plus, my pictureboxes all need to have transparent backgrounds.  That slows my app even more. I know that the alternative is having one big picturebox and using the Paint event.  I've tried that back in Visual Basic 2003 and it was a total nightmare. Can anyone help me optimize my app so that all the pictureboxes don't slow it ...Show All
