HowTo: Convert a string to proper case in a label expression

Summary

Instructions provided describe how to use a label expression to convert a string that is upper case, lower case or mixed case to proper case. For example, if a string that is in the following formats:

"hello world"
"HELLO WORLD"
"hELLO wORLD"
"Hello World"

The following label expression will convert the string to: "Hello World".

For information on how to do the equivalent steps in the ArcMap field calculator, see the link in the Related Information section below.

Procedure

In the ArcMap field calculator, use the VBA expression StrConv to convert a string to proper case. However, the default label expression parser VBScript does not have this method. The following label expression works around this VB Script limitation:

1. Open the Label Expression dialog box.
2. Click the Advanced button.
3. Use the following code when converting only one field. Remember to change the name of the field [MyFieldName] to match the field name in the two locations below where it is referenced. 

Function FindLabel ([MyFieldName])

  FindLabel = PCase([MyFieldName])

End Function

Function PCase(strInput)

  Dim iPosition

  Dim iSpace

  Dim strOutput

  iPosition = 1

  Do While InStr(iPosition, strInput, " ", 1) <> 0

    iSpace = InStr(iPosition, strInput, " ", 1)

    strOutput = strOutput & UCase(Mid(strInput, iPosition, 1))

    strOutput = strOutput & LCase(Mid(strInput, iPosition + 1, iSpace - iPosition))

    iPosition = iSpace + 1

  Loop

  strOutput = strOutput & UCase(Mid(strInput, iPosition, 1))

  strOutput = strOutput & LCase(Mid(strInput, iPosition + 1))

  PCase = strOutput

End Function

 4. Use the following code when converting many fields at once. Remember to change the field names in the code below. Add more fields if required.

Function FindLabel ([MyFieldName1], [MyFieldName2], [MyFieldName3])
  FindLabel = PCase([MyFieldName1] & " " & [MyFieldName2] & " " & [MyFieldName3])
End Function

Function PCase(strInput)
  Dim iPosition
  Dim iSpace
  Dim strOutput
  iPosition = 1
  Do While InStr(iPosition, strInput, " ", 1) <> 0
    iSpace = InStr(iPosition, strInput, " ", 1)
    strOutput = strOutput & UCase(Mid(strInput, iPosition, 1))
    strOutput = strOutput & LCase(Mid(strInput, iPosition + 1, iSpace - iPosition))
    iPosition = iSpace + 1
  Loop
  strOutput = strOutput & UCase(Mid(strInput, iPosition, 1))
  strOutput = strOutput & LCase(Mid(strInput, iPosition + 1))
  PCase = strOutput
End Function

Multiple Checkbox Select/Deselect Using JQuery

Almost all the user interfaces that I have created had this functionality of selecting multiple items from a list to process them or delete them. Although its very very easy to implement this functionality in Javascript, using jQuery for this is real fun. I will show you a simple implementation of adding multiple checkbox select and deselect functionality to any webpage. We will have a table with some data in it and checkbox in each row. There will be a select all checkbox in the header of the table. If user select/deselect the selectall checkbox, all the checkbox in table will get selected or deselected accordingly. Now one more thing we would like here to add is, suppose user select all the checkbox one by one then the selectall checkbox should be automatically gets selected. And if user click selectall first and then unchecks any of the checkbox, then the selectall also should be unchecked automatically.

Check Special Character in File folder name using regular expression

In Javascript:

function checkFolderName(str) {
    strreg = /^[\w\-]+$/
    var strregx = new RegExp(strreg);
    if (strregx.test(str)) {
        //alert("OK")
        return false
    }
    else {
        //alert("Not OK")
        return true
    }
}

function checkFileName(str) {
    var name = str.substr(0, str.lastIndexOf('.'));
    var ext = str.substr(str.lastIndexOf('.') + 1);
    ext = ext.toLowerCase();
    //alert(name);
    //alert(ext);
    strreg = /^(?!.*  )(?!.*__)(?!.*--)[\w -]+$/    //Check alphanumeric with underscore and Hyphan and two consecutive spaces,underscore,hyphen
    //strreg = /^[a-zA-Z0-9_\-]+$/          //Check alphanumeric with underscore and Hyphen
    var strregx = new RegExp(strreg);
    if ((strregx.test(name)) && (ext != "asp") && (ext != "aspx") && (ext != "dll") && (ext != "cmd") && (ext != "bat") && (ext != "exe")) {
        //alert("OK")
        return false
    }
    else {
        //alert("Not OK")
        return true
    }
}

How To use function:

if(checkFolderName(document.getElementById("abc").value))
{
    alert("Please don't use special char in Foldername.")
}

if(checkFileName(document.getElementById("abc").value))
{
    alert("Please don't use special char in File Name.")
}

Textbox autocomplete using jquery in asp .net

In this asp net tutorial we will learn how to use Jquery Autocomplete. Jquery Autocomplete is a very useful plugin which allows users to quickly search and select from list of values when they type into texbox control.

Whenever user starts typing in Autocomplete enabled textbox he will see a list of suggestions based on the characters he has typed in the textbox. After getting the desired result user can select required value from the autocomplete list which will displayed in the textbox.
   

You can provide static values in the form of array or you can also bind Jquery Autocomplete with database. In this tutorial we will bind our Jquery Autocomplete plugin with database. I will use northwind database for the demonstration purpose you can choose your own database. 

Lets get started with sample application: 

Step1: Create a new asp .net website.

Step2: Create a default.aspx page and create a textbox control in it.

<asp:textbox runat="server" id="txtAutoComplete" cssclass="autosuggest"></asp:textbox>




Step3:  Add neccessary Jquery and Css files. Here I am using CDN(Content Delivery Network) for Jquery and CSS files. You can use CDN or you can download files from Jquery website to your project. Put this code between “Head” tag.




<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/base/jquery-ui.css" rel="stylesheet" type="text/css">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"></script>

Step4: Write a method to get list of employees from database and return to Jquery Autocomplete. For this example I am using WebMethod to get and return list of employees from Northwind database.



Add Connection String:




<connectionstrings>      <add name="myConnection" connectionstring="Data Source=Sqlservername;user id=sa;password=yourpassword;Initial Catalog=Northwind"></add>  </connectionstrings>




Add following namespaces:







using System.Web.Services;


using System.Data.SqlClient;

using System.Configuration;



Create Following method in Default.aspx.cs page:







[WebMethod]


    public static List<string> getCustomerNames(string prefixText)

    {

        List<string> customers = new List<string>();



        using (SqlConnection conn = new SqlConnection())

        {

            conn.ConnectionString = ConfigurationManager.ConnectionStrings["myConnection"].ConnectionString;

            using (SqlCommand cmd = new SqlCommand())

            {

                cmd.CommandText = "select contactName As Name  from Customers where " +

                "contactName like @SearchText + '%'";

                cmd.Parameters.AddWithValue("@SearchText", prefixText);

                cmd.Connection = conn;

                conn.Open();

                using (SqlDataReader dr = cmd.ExecuteReader())

                {

                    while (dr.Read())

                    {

                        customers.Add(dr["Name"].ToString());

                    }

                }

                conn.Close();

            }



        }

        return customers;

    }</string></string></string>





Step5:  Call Webmethod using Jquery and bind values for Jquery Autocomplete.Put this code between your page’s head tag.




<script type="text/javascript">
       $(document).ready(function () {
           SearchText();
       });
       function SearchText() {
           $(".autosuggest").autocomplete({
               source: function (request, response) {
                   $.ajax({
                       type: "POST",
                       contentType: "application/json; charset=utf-8",
                       url: "Default.aspx/getCustomerNames",
                       data: "{'prefixText':'" + document.getElementById('txtAutoComplete').value + "'}",
                       dataType: "json",
                       success: function (data) {
                           response(data.d);
                       },
                       error: function (result) {
                           alert("Error");
                       }
                   });
               }
           });
       }
   </script>

How to check if multiple textbox have same value?

//First get the counting of textbox
             flag = false;

            $(".dyntxt").each(function () {
                if ($(this).val() == "") {

                    $(this).focus();
                    return false;
                }
            cnt =cnt +1
            });
//To Check Textbox is fiiled or not
            if (flag) {
                alert("Please fill student name")
                return false;
            }
            else if (!flag) {
                count = Number(cnt - 1);
               //count = Number((document.frmDefineSSS.cboTeamSize.selectedIndex) - 1);
                flagSame = false;
//to check the duplicate value
                for (i = 1; i <= count; i++) {
                    for (j = i + 1; j <= count + 1; j++) {

                        if ($("#txtStudName" + [i]).val() == $("#txtStudName" + [j]).val()) {
                            alert("Team Member can't be same.");
                            $("#txtStudName" + [i]).css("background-color", "yellow");
                            $("#txtStudName" + [j]).css("background-color", "yellow");
                            flagSame = false;
                            return false;

                        }
                        else {
                            $("#txtStudName" + [i]).css("background-color", "white");
