Hi,

you can tell Parse and TryParse what it is you want to allow, e.g.:

int val;
bool OK=int.TryParse("12,345", NumberStyles.AllowThousands, null, out val);

Hello
Tanks for your help. I used your code like below :

Int64 val;<br />
bool ok;<br />
ok = Int64.TryParse(TextBox1.Text, NumberStyles.AllowThousands, null, out val);<br />
TextBox1.Text = Convert.ToInt64(val.ToString()).ToString("#,###");<br />

The problem accures after typing more than 4 numbers. Because cursor qoes to the left side of numbers, For example i want to type 12345, after typing 4 in typing 5 it TextBox shows : 51,234
Can you help me on this?

Regards

use this code:
by this code,your problem is ok

private void textBox1_TextChanged(object sender, EventArgs e)
       {
           try
           {
               string ss = textBox1.Text.Replace(",", "");
               int d = int.Parse(ss);
               string gg = String.Format("{0:###,###,###}", d);
               textBox1.Text = gg;


               textBox1.SelectionStart = textBox1.Text.Length;
           }
           catch
           {
           }

       }

try
{
string ss = textBox1.Text.Replace(",", "");
int d = int.Parse(ss);
string gg = String.Format("{0:###,###,###}", d);
textBox1.Text = gg;

textBox1.SelectionStart = textBox1.Text.Length;
}
catch
{
}

While reading the physical address of each card using WMI works, I've found it to be a little slow. If speed isn't your main concern, this is fine. However, if you want something slightly faster, then you could look into the NetworkInterface class

I'd use the NetworkInterface class over WMI.

Also, if you're going to use the MAC for some security related conern, make sure you're using the SAME MAC every time. It's possible the machine will have multiple network interfaces and will have multiple MAC's. Also, there are additional interfaces that will show up, even though there is no physical adapter for them!

Warning: the MAC address can be spoofed; it equals the hardware MAC address when the system boots and/or the network connects, you can easily modify it afterwards. So it is not a reliable way for achieving software protection.

Creating a ClientProxy from Scratch

Lochnagar4-Sep-09 8:22

4-Sep-09 8:22

Hello All,
So, I am usually a .NET developer now working in a ColdFusion shop. I found out recently that the
new .NET WCF format Web Services don't play as nicely as some would have you believe, specifically,
they are quite difficult to access successfully through ColdFusion. . . . The easy answer, create
a .NET Proxy to do the actual web interaction and access the local .NET DLL from ColdFusion (much
easier to integrate). So, that is a little background on the overall project.

Now for the Question:
We are having issues with the Skew Value when trying to send to the web service. We have asked the
other end (our client) to see if they can update on their end, but we want to make sure that we are
updating on our end as well. If this was a .NET only application, I could just add three or four
lines to my app.config or web.config file and this would be an easy fix. But, since working with
ColdFusion, I can't use an app.config or web.config file with my .NET DLL (REALLY wish I could).
So, I am creating the complete proxy from scratch, and I could just use some help looking over my
work, making sure that I am doing it correctly, and making sure that I am actually setting the Skew
Value correctly.

Here is the Method that I create the Client Proxy for calling the web service (basically having to
create in code everything that would normally be in the app.config/web.config):

private static NameSpace.Web_Service.ClientProxy createClientProxy()
{
    // Create MyBinding WSHttpBinding for the Client
    System.ServiceModel.WSHttpBinding myBinding = new System.ServiceModel.WSHttpBinding();
    // Setup MyBinding Basic Values
    myBinding.Name = "SecureBinding";
    myBinding.CloseTimeout = new TimeSpan(0, 1, 0);
    myBinding.OpenTimeout = new TimeSpan(0, 1, 0);
    myBinding.ReceiveTimeout = new TimeSpan(0, 30, 0);
    myBinding.SendTimeout = new TimeSpan(0, 1, 0);
    myBinding.BypassProxyOnLocal = false;
    myBinding.TransactionFlow = false;
    myBinding.HostNameComparisonMode = System.ServiceModel.HostNameComparisonMode.StrongWildcard;
    myBinding.MaxBufferPoolSize = 524288;
    myBinding.MaxReceivedMessageSize = 65536;
    myBinding.MessageEncoding = System.ServiceModel.WSMessageEncoding.Text;
    myBinding.TextEncoding = Encoding.UTF8;
    myBinding.UseDefaultWebProxy = true;
    myBinding.AllowCookies = false;

    // Setup MyBinding.ReaderQuotas
    myBinding.ReaderQuotas.MaxDepth = 32;
    myBinding.ReaderQuotas.MaxStringContentLength = 8192;
    myBinding.ReaderQuotas.MaxArrayLength = 16384;
    myBinding.ReaderQuotas.MaxBytesPerRead = 4096;
    myBinding.ReaderQuotas.MaxNameTableCharCount = 16384;

    // Setup MyBinding.ReliableSession
    myBinding.ReliableSession.Ordered = true;
    myBinding.ReliableSession.InactivityTimeout = new TimeSpan(0, 10, 0);
    myBinding.ReliableSession.Enabled = false;

    // Setup MyBinding.Security.Mode
    myBinding.Security.Mode = System.ServiceModel.SecurityMode.TransportWithMessageCredential;

    // Setup MyBinding.Security.Transport
    myBinding.Security.Transport.ClientCredentialType = 
        System.ServiceModel.HttpClientCredentialType.None;
    myBinding.Security.Transport.ProxyCredentialType = 
        System.ServiceModel.HttpProxyCredentialType.None;
    myBinding.Security.Transport.Realm = String.Empty;

    // Setup MyBinding.Security.Message
    myBinding.Security.Message.ClientCredentialType = 
        System.ServiceModel.MessageCredentialType.UserName;
    myBinding.Security.Message.NegotiateServiceCredential = true;
    myBinding.Security.Message.EstablishSecurityContext = true;

    // Create ContractDescription for MyEndpoint
    System.ServiceModel.Description.ContractDescription myContractDesc = 
        new System.ServiceModel.Description.ContractDescription("Web_Service_Name", "Web_Service");

    // Create EndpointAddress for MyEndpoint
    System.ServiceModel.EndpointAddress myepAddress = 
        new System.ServiceModel.EndpointAddress("https://www.webservicelocation.com/WebServiceName/Service.svc");

    // Create MyEndpoint Service Endpoint for the Client
    System.ServiceModel.Description.ServiceEndpoint myEndpoint = 
        new System.ServiceModel.Description.ServiceEndpoint(myContractDesc, myBinding, myepAddress);

    // Create Proxy Service
    NameSpace.Web_Service.Client myProxy = new NameSpace.Web_Service.Client(myBinding, myepAddress);
    BindingElementCollection test = myProxy.ChannelFactory.Endpoint.Binding.CreateBindingElements();
    SymmetricSecurityBindingElement security = new SymmetricSecurityBindingElement();
    security.LocalClientSettings.MaxClockSkew = TimeSpan.FromMinutes(30.00);
    security.LocalServiceSettings.MaxClockSkew = TimeSpan.FromMinutes(30.00);
    SecurityBindingElement bootStrap = new SymmetricSecurityBindingElement();
    bootStrap.LocalClientSettings.MaxClockSkew = TimeSpan.FromMinutes(30.00);
    bootStrap.LocalServiceSettings.MaxClockSkew = TimeSpan.FromMinutes(30.00);
    SecureConversationSecurityTokenParameters secureTokenParams = 
        new SecureConversationSecurityTokenParameters(bootStrap);
    security.ProtectionTokenParameters = secureTokenParams;
    test.Add(security);

    // Add Credentials to Proxy Service
    myProxy.ClientCredentials.UserName.UserName = "MyUserName";
    myProxy.ClientCredentials.UserName.Password = "MyPassword";

    // Return Proxy Service
    return myProxy;
}

And the app.config file that I used to create it is:

I've a string that contains ShowVideo('sdsdsdsdsd,1,2'); and I want to replace it with new string but before replace I need to retrieve its values(i.e. 'sdsdsdsdsd,1,2'). So I thought to use Regex but I stuck. Actually I'm not good in that thing...I tried following code but I dunno what to write next. I read alot of examples and articles but I couldn't figure it out that how this thing is working...

string data = "NotShowVideo('sdsdsdsdsd,1,2'); ShowVideo('sdsdsdsdsd,1,2');     %     ";

Regex r = new Regex(@"ShowVideo"); // what to write here
MatchCollection mc = r.Matches(data);
for (int a = 0; a < mc.Count; a++)
{
    Match m = mc[a];
}

any help would be nice
