Add in some code to set the backgroundcolor of the control you're manipulating; that way you can check easily whether or not you're talking to the correct control, and whether all other code works.

If it does, then there's a chance that the "enabled" property is being reset or overwritten by another part of the code.

One thing to be aware of. You're doing a case sensitive comparison of a string there. What happens if the case doesn't match what you're testing for (hint, you won't trigger any of your enable conditions)?

{

Menu mymenu = (Menu)Form.FindControl("Menu1");
MenuItem mi = mymenu.FindItem("Programs");
mi.Selected = true;

how can I convert string ('1213,1415') to XML like this:

<planyears>
    <planyear>1213</planyear>
    <planyear>1415</planyear>
</planyears>

It is as simple as reading alphabets,

static void Main(string[] args)
        {
            string strInput = "('1213,1415')";

            //Manipulate the string
            strInput = strInput.Trim(new char[] { '(', '\', ')' });
            IList<string> strings = strInput.Split(',');

            //Generate the XML
            XElement planyears = new XElement("planyears");
            foreach (string str in strings)
            {
                planyears.Add(new XElement("planyear", str));
            }
        }

RFID Program

Hi,

i have a problem for making rfid program with socket in c#.

i try this code :

socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
IPAddress[] ip = Dns.GetHostAddresses(ipLoc);
IPEndPoint ep = new IPEndPoint(ip[0],23);
socket.Connect(ep);
Console.WriteLine("Connected");

char open1 = (char)13;
char open2 = (char)10;

//char[] myArray = new char[] { open1, open2 };

Byte[] sendBytes2 = Encoding.ASCII.GetBytes(Convert.ToString(open1));
Byte[] sendBytes = Encoding.ASCII.GetBytes(Convert.ToString(open2));
//Byte[] sendBytes2 = Encoding.ASCII.GetBytes("10");
//socket.Send(sendBytes);
socket.Send(sendBytes2);
socket.Send(sendBytes);
count = socket.Receive(buffer);
Console.WriteLine(System.Text.Encoding.ASCII.GetString(buffer, 0, count));

//socket.Shutdown(SocketShutdown.Both);

socket.Disconnect(true);
socket.Close();

but i not have a result.. rfid card not read in console and gate cannot to open..
i hope all of you can help my problem..

thanks very much..

Nowhere near enough information.

I presume the socket code is trying to talk to the RFID receiver? Not the gate? It appears you are sending it a CRLF - what's the purpose of doing this?

It is probably necessary for you to have the specification for the RFID reader.
Usually there is code samples available if you go to the vendors site.

First, What do you mean by "I have done", does it mean you having nothing else to learn in .Net?

Now, to your question,
Go back 10 years (may be to the year 2001)and recall how the .Net and C# was doing. Visualize the changes since that.

however, in next 15 years or so, the changes is going to be further sharp. No one can predict this.

Best ways are to,
1. Not only learn a language or technology, Learn the technique "How to learn and adopt"
2. Learn to travel with the time

Database first Entity framework with repository pattern

We are now in the planning stage of the next web based project using C#, MVC 5 and Entity framework 6. We are discussing about framing the project using the Repository pattern. We already have the full database ready. So, it is going to be Database first.

Now, my question : Is it feasible / worth using Repository pattern with database first approach? I got this doubt because, many sources and examples found in internet are Code first approach. If it is possible can you please provide me any advice or online/article sources to refer. Thanks.

I welcome any ideas or suggestions on Repository pattern.

Of course you can. Mind you, I would suggest that you don't just concentrate on this one pattern. I find that it goes hand in hand with the Unit Of Work pattern to help simplify things.

As Pete O'Hanlon said, you can. We use the Repository pattern + Unit of Work on the project I'm on right now. While we do use Code First, there is no reason it can't apply to Database First as well. Someone can correct me if I'm wrong, but I don't think the purpose of the Repository pattern was designed specifically for Code First. One advantage of using Repo is testing, another is dependency injection. It's simple to test using a Repository, from what I can tell here.

Compare 2 tables

How do I compare two tables and get the difference?
Dim dtBenefitsCurrent As New DataTable
dtBenefitsCurrent = objDB.GetPlanBenefits(groupID, planID, SequenceNumber)
Dim dtBenefitsPreviousYear As New DataTable
dtBenefitsPreviousYear = objDB.GetPlanBenefits(PreviousgroupID, PreviousplanID, PreviousSequenceNumber)
Dim dyDifference ????

Eddy Vluggen17-Sep-14 5:15

Do you want to compare their structure, or their data?

The most obvious way is looping through the data, and looking whether the second table has the same. Exit as soon as they are not, or loop until the end and return a list of differences.

AFAIK, there's no built-in functionality to compare datatables and get a diff.
