When I read the file using C#, I found empty entry after each element with value. Here is the code block,

TextReader fileReader = new StreamReader(@”C:\members.txt”);

string fileText = fileReader.ReadToEnd();

char[] newLineChar = Environment.NewLine.ToCharArray();

string[] memberIds = fileText.Split(newLineChar, StringSplitOptions.RemoveEmptyEntries);

In order to remove the empty elements, in the Split method, I passed the  StringSplitOptions.RemoveEmptyEntries, which gave the desired result.

Here is the code snippet,

public class ClinicInfo
{
internal string ClinicID { get; set; }
internal string ClinicName { get; set; }

public override string ToString()
{
return ClinicName;
}
}

//Code for binding the data into ComboBox

IEnumerable<ClinicInfo> clinics = DBGateway.GetActiveClinics();

ClinicCmbBox.DataSource = clinics;
ClinicCmbBox.ValueMember = “ClinicID”;
ClinicCmbBox.DisplayMember = “ClinicName”;

Everything was looking good except the Access Modifiers (internal) for the properties in ClinicInfo class.

When I changed that to public as shown below, everything worked fine.

public string ClinicID { get; set; }
public string ClinicName { get; set; }

So, the properties you are setting in ‘ValueMember’ and ‘DisplayMember’ should be public.

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
LoadLeftNav();
}
}

private void LoadLeftNav()
{
string root = @”D:\Projects”;
DirectoryInfo rootDirectory = new DirectoryInfo(root);
TreeNode rootNode = new TreeNode(rootDirectory.Name);
rootNode.Value = rootDirectory.FullName;
rootNode.ToolTip = rootDirectory.Name;
TreeView1.Nodes.Add(rootNode);
LoadOcean(rootNode, rootDirectory);
}

private void LoadProjects(TreeNode rootNode, DirectoryInfo rootDirectory)
{
DirectoryInfo[] compaines = rootDirectory.GetDirectories();

foreach (DirectoryInfo company in compaines)
{
TreeNode node = new TreeNode(company.Name);
node.Value = company.FullName;
rootNode.ChildNodes.Add(node);
node.ToolTip = company.Name;
this.LoadOcean(node, company);
}
}

a. Stop the application pool of the application which is consuming the WCF service.

b. Browse to the C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

c. Delete the temp folder of the application which is using the WCF service. (The reason is, even though you restart IIS, the corrupted files will be here and it will cause the issue)

e. Start the application pool.

That’s it! This resolved my issue and the application started to work normally. Although, I am not clear on what exactly happened to cause this issue, I found the solution.

The following javascript will give you an idea of setting css class to a control for IE and other browsers.

//Javascript

var anchl = document.getElementById(‘largeFontSwitch’); //Id of the control

//Remove class
anchl.setAttribute(“class”, “”); //Other browsers
anchl.className = “”; //IE

//Set class

anchl.setAttribute(“class”, “selectedFont”); //Other browsers
anchl.className = “selectedFont”; //IE

The functionality of my http handler is, it receives request from an ASP.NET page, processes it and sends back a response .

When I right clicked the ‘Process Request’ method in Http Handler and selected ‘Create unit tests…’, Visual Studio created unit test methods for me. But, when I tried to run those tests, I got the following error message, “The test adapter ‘WebHostAdapter’ threw an exception while running test…”.

So, the elegant way I can think of testing my custom http handler is, post data to the http handler url using HttpWebRequest and get the response back using HttpWebResponse.

Here is the unit test which I have written and it is working perfectly,

[TestMethod]
public void AuthTest()
{
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = postData += (“&username=” + “testuser@gmail.com“);
postData += (“&password=” + “testpassword”);

byte[] data = encoding.GetBytes(postData);

HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create(“https://customerdemoserver/WebApplication2/Auth.ashx“);
myRequest.Method = “POST”;
myRequest.ContentType = “application/x-www-form-urlencoded”;
myRequest.ContentLength = data.Length;
myRequest.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;

Stream newStream = myRequest.GetRequestStream();

newStream.Write(data, 0, data.Length);
newStream.Close();

HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
Stream stream = myResponse.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string result = reader.ReadToEnd();

Assert.IsNotNull(result);
}

Now, I am able to verify the functionality of my custom http handler, using the above unit test.
