TryParse() returns a bool so I doubt that is what you want.

Have you checked what the "Convert.ToDecimal(ViewState["_first_min_wage"])" and "Convert.ToDecimal(txtSalary.Text)" calls return?

Yes. They return values like 7.55 and 8.55

TryParse will return a boolean... the values will be stored in d1 and d2. You can do something like this:

string strd1 = "5", strd2 = "6";
Decimal d1, d2;
if (Decimal.TryParse(strd1, out d1) && Decimal.TryParse(strd2, out d2))
{
    if (d1 < d2)
    {
        // Do something...
    }
}

However, if the value stored in the view state is not a string, you may only have to cast rather than parse:

Decimal startVal = 55;
ViewState["myVal"] = startVal;
Decimal val = (Decimal)ViewState["myVal"];

Perfect, that worked. Comparing them using d1 and d2

I have an application that uses a net remoting server that that is on a public network that as no fixed ip address.

When the server changes the ip all the clientes steel connect to the old ip Address even if a call activator.GetObject

width the name of the server.

The service is running in siglecall Mode

and props["useIpAddress"] = false;.

TcpChannel

Can some one help me to solve this problem?

If your clients don't try an resolve the name with the DNS server that is maintaining your remote servers name/IP address, there's no way they are going to be able to connect.

You have two choices. Either move your server to a more "stable" static IP address or the clients will have to specifically be coded to resolve the IP of your server name with the DynmiacDNS of your servers hosting company.

Presumably you have already verified that the DHCP record is getting pushed as soon as the IP changes.

AND you have verified that a NEW client picks up the new IP address.

If either of the above is not true then the question has nothing to do with C#.

If both of the above is true then it might help to create a small bit of code that demonstrates exactly what you are doing. It might be your code or that a .Net API is 'helpfully' caching something it shouldn't.

Yes the ip of the server changes and i can ping the server using the new ip address.

the code i use is this:

string serverAddress = ServerAddress;
int LocalPort = localport;
IDictionary props = new Hashtable();
props["name"] = "DbSync";
props["timeout"] = 60000*60;
props["useIpAddress"] = true;
props["socketCacheTimeout"] = 1;
BinaryClientFormatterSinkProvider clientProv = new BinaryClientFormatterSinkProvider();
TcpClientChannel channel = new TcpClientChannel(props, clientProv);
ChannelServices.RegisterChannel(channel,false);
_ServerURL = string.Format("tcp://{0}:{1}/RDbSyncronizer.soap", adresses[0], LocalPort.ToString());
RemoteSyncronizer =Activator.GetObject(typeof(ServerSyncronizer), _ServerURL) as ServerSyncronizer;

and when a connection fail i call to

RemoteSyncronizer =Activator.GetObject(typeof(ServerSyncronizer), _ServerURL) as ServerSyncronizer;

again.

if i restart the service in the client he connects to the new IP and work until the ip of the server changes again.

My guess is that some part of the remoting infrastructure is caching server/service combinations, so it doesn't have to go and shake hands with a new server each time you create an instance of a remote object. You will need to call some method to clear that cache or force a reconnection. But I have not worked with remoting so I can't provide any detailed help.

Either that is stated incorrectly or it has nothing to do with what I said.

I have no doubt that the IP changes. And once it changed pinging it would be expected.

That however has nothing to do with DHCP resolution.

Hello all, I am now learning to program in C#. I initialised an object of OpenFileDialog and set the filter. When the dialog box opens for the first time, everything seems to be OK. Files of the type specified in the filter a shown. But when I change Files of Type to All files which I have set with *.*, the list of files shown is not automatically updated as is expected. I don't know what is wrong. The following is the code I have.

using System;
using System.Drawing;
using System.Windows.Forms;


class MyForm : Form
{
    public static void Main()
    {
        Application.Run(new MyForm());
    }

    public MyForm()
    {
        Text = "My Form";

        Menu = new MainMenu();
        Menu.MenuItems.Add("&File");
        Menu.MenuItems[0].MenuItems.Add("&Open...", new EventHandler(FileOpenOnClick);
    }

    void FileOpenOnClick(object obj, EventArgs ea)
    {
       OpenFileDialog fodlg = new OpenFileDialog();
       
       fodlg.Filter = "Text Documents (*.txt)|*.txt|All Files (*.*)|*.*";

       if (fodlg.ShowDialog() == DialogResult.OK)
       {
           // some code here
       }

       // some code here
    }
}

I am using Visual Studio 2005 with .Net Framework 2.0. From the code above, I have only set the Filter property. When the file open dialog box opens first with Text documents, it works fine but when I change the Files of Type from the combobox to All Files, the dialog box is not updated to show all files. What could be wrong? What am I missing? Please help.

There's nothing wrong with the code. Your code has no control over the refresh in the dialog.

The problem has to be something else in your system, though I have no idea what.

I changed two things to get your code working; added the STAThread attribute and changed the class to OpenFileDialog, as shown below;

[STAThread()]
public static void Main()
{
    Application.Run(new MyForm());
}

void FileOpenOnClick(object obj, EventArgs ea)
{
    System.Windows.Forms.OpenFileDialog fodlg = new System.Windows.Forms.OpenFileDialog();

    fodlg.Filter = "Text Documents (*.txt)|*.txt|All Files (*.*)|*.*";

The problem is not in your code. I just checked
with following:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog fodlg = new OpenFileDialog();

        fodlg.Filter = "Text Documents (*.txt)|*.txt|All Files (*.*)|*.*";

        if (fodlg.ShowDialog() == DialogResult.OK)
        {
            // some code here
        }
    }
}

and it works like charm! Be aware that the dialog class is called OpenFileDialog and not FileOpenDialog.

You should search elsewhere, code is all right!

Yes, in all seriousness I actually use it quite a lot. I've learnt on environments where the debugger is either non-existent or so flaky one shouldn't use it, so I have a habit of dumping all relevant information to the console and looking to see which bits are wrong.
