try this Example to Find IP and IP Location:-

1. Create new website project and Go to solution explorer.

2. Right-click on your project name

3. Click on ‘Add Web Reference’

4. Enter this address: http://tools.webmastermafia.com/GeoIPChecker.asmx

5. Drow some Button control and TextBox Control named txtIP

6. Enter this code into button_click event:

C#:
com.webmastermafia.tools.GeoIPChecker GEO = new com.webmastermafia.tools.GeoIPChecker();
lblResult.Text = GEO.GetCountry(“test@webmastermafia.com”, “test”, txtIP.Text, “CountryName”);

Visual Basic:
Dim GEO As com.webmastermafia.tools.GeoIPChecker = new com.webmastermafia.tools.GeoIPChecker();
lblResult.Text = GEO.GetCountry(“test@webmastermafia.com”, “test”, txtIP.Text, “CountryName”)

This is for check country name by IP. If you want to check City name, than use this code:

C#:
com.webmastermafia.tools.GeoIPChecker GEO = new com.webmastermafia.tools.GeoIPChecker();
lblResult.Text = GEO.GetCity(“test@webmastermafia.com”, “test”, txtIP.Text, “City”);

Visual Basic:
Dim GEO As com.webmastermafia.tools.GeoIPChecker = new com.webmastermafia.tools.GeoIPChecker();
lblResult.Text = GEO.GetCity(“test@webmastermafia.com”, “test”, txtIP.Text, “City”)

Increase file Uploaded size

Filed under: ASP.Net — yasserzaid @ 1:37 pm

By Default, we can’t upload files with size more the 4Mb, because it’s already configured in the machine.web file. as follows:
<httpRuntime maxRequestLength =”4096″/> where 4096 in kb

Although you can overload these settings in the web.config file

add in the <system.web>

Which allows uploading files up to for example 5120 = 5Mb.

Hope this helps

Good Luck

4) In code behind in Button Click Event:-

protected void btnAddFile_Click(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(1000);
        //string filename = System.IO.Path.GetFileName(fileUp.FileName);
        //fileUp.SaveAs(Server.MapPath(“~/Upload/”) + filename);
        string File = Guid.NewGuid().ToString() + Path.GetExtension(fileUp.FileName);
        fileUp.SaveAs(Server.MapPath(“~/Upload/”) + File);
    }

Disable and Restrict Copy Cut and Paste from on a Textbox

Filed under: ASP.Net, Javascript — yasserzaid @ 4:08 pm

try this example to Disable and Restrict Copy Cut and Paste from on a textbox using Javascript

You will need two javascript functions for this:

    function noCopyMouse(e) {
        var isRight = (e.button) ? (e.button == 2) : (e.which == 3);

        if(isRight) {
            alert(‘You are prompted to type this twice for a reason!’);
            return false;
        }
        return true;
    }

    function noCopyKey(e) {
        var forbiddenKeys = new Array(‘c’,'x’,'v’);
        var keyCode = (e.keyCode) ? e.keyCode : e.which;
        var isCtrl;

        if(window.event)
            isCtrl = e.ctrlKey
        else
            isCtrl = (window.Event) ? ((e.modifiers & Event.CTRL_MASK) == Event.CTRL_MASK) : false;

        if(isCtrl) {
            for(i = 0; i < forbiddenKeys.length; i++) {
                if(forbiddenKeys[i] == String.fromCharCode(keyCode).toLowerCase()) {
                    alert(‘You are prompted to type this twice for a reason!’);
                    return false;
                }
            }
        }
        return true;
    }

And a wee bit of code-behind to handle the two events for the textbox(es):

Textbox1.Attributes.Add(“onmousedown”, “return noCopyMouse(event);”)
Textbox1.Attributes.Add(“onkeydown”, “return noCopyKey(event);”)

Hope this helps

Good Luck

Allow Users to Change Their Email Address using Membership

Filed under: ASP.Net — Tags: Membership — yasserzaid @ 5:55 pm

try this example to Allow Users to Change Their Email Address using Membership :-

in code behind :-

protected void Page_Load(object sender, EventArgs e)
{
    //add theses lines
    if (!IsPostBack)
   {
      MembershipUser user = Membership.GetUser();
       if (user != null)
      {
         txtEmail.Text = user.Email;
      }
   }
}
Then, we need to add the method that fires when the Change Email button is clicked.

//add this methodprotected void btnEmail_Click(object sender, EventArgs e)
{
   if (IsValid)
   {
      MembershipUser user = Membership.GetUser();
       if (user != null && txtEmail.Text != user.Email)
       {
         user.Email = txtEmail.Text;
          try
         {
            Membership.UpdateUser(user);
            lblEmailChangeSuccess.Text = “Your email address was successfully changed.”;
         }
         catch (ProviderException)
         {
            lblEmailChangeFail.Text = “A user with that email address already exists. Your address was not changed.”;
         }
      }
   }
}

Hope this helps
