There is no doubt, you can use either appSettings or connectionStrings. ConnectionStrings has built in support in the ConfigurationManager class where as using the appSettings you have to do yourself. Also, connectionSettings is where other components will look by default for connection information.

I have a gridview in my form which I am populating data using SqlDataSource. The gridveiw has insert, update and delete. But somehow I forgot to write the RowEditingEvent.
Upon my surpise, when I clicked on Edit button in the grid while executing, the row automatically become editable. Obviously, I have declared the columns with EditItemTemplate.
Is the RowEditing Event not required when I use ObjectDataSource or SqlDataSource? I couldn't find such event in the msdn example also MSDN Link
Thanks

Hello team,
I am in a very critical situation, wherein I will have to take an important decision. I have some existing C programs. Those C programs takes input from .DBF (dBase III) files and .BTR (BTRIEVE) files.
I have been given 2 options:
1) Convert .DBF files to .BTR files and .BTR files to .DBF files. These convertion can be done using .NET. If yes, give me some code snippets or some links where I can get the code.
2) Or using .NET is there any other way to replace this BTRIEVE concept itself? In other ways, instead of BTRIEVE, can we go for some other technology?
Pls advise....

Try this:
private void checkButtonDoubleClick(Button button)
{
System.Text.StringBuilder sbValid = new System.Text.StringBuilder();
sbValid.Append("if (typeof(Page_ClientValidate) == 'function') { ");
sbValid.Append("if (Page_ClientValidate() == false) { return false; }} ");
sbValid.Append("this.value = 'Please wait...';");
sbValid.Append("this.disabled = true;");
sbValid.Append(this.Page.ClientScript.GetPostBackEventReference(button, ""));
sbValid.Append(";");
button.Attributes.Add("onclick", sbValid.ToString());
}

You look like too lazy to even Google it out. I am sure there would be no point asking what have you tried till now.
Go here:
http://www.google.com
http://www.codeproject.com
Use keywords like - chat, messenger, etc. You will get lots of articles.

(sigh) People these days are used to spoonfeeding. Help yourself buddy. research first on what you want to do and then based on your researches, ask questions. It would be an interesting discussion if it was done that way.

Following is my code for login:
void Page_Load(object sender, EventArgs e) {
string appURL = "http://www.mysite.com/Login.aspx";
string strPostData = String.Format("login={0}&password={1}",
"myloginname", "mypassword");
// Setup the http request.
HttpWebRequest wrWebRequest = WebRequest.Create(appURL) as
HttpWebRequest;
wrWebRequest.Method = "POST";
wrWebRequest.ContentLength = strPostData.Length;
wrWebRequest.ContentType = "application/x-www-form-urlencoded";
wrWebRequest.CookieContainer = new CookieContainer();
// Post to the login form.
StreamWriter swRequestWriter = new
StreamWriter(wrWebRequest.GetRequestStream());
swRequestWriter.Write(strPostData);
swRequestWriter.Close();
// Get the response.
HttpWebResponse hwrWebResponse =
(HttpWebResponse)wrWebRequest.GetResponse();
// Have some cookies.
CookieCollection ccCookies = hwrWebResponse.Cookies;
// Read the response
StreamReader srResponseReader = new
StreamReader(hwrWebResponse.GetResponseStream());
string strResponseData = srResponseReader.ReadToEnd();
srResponseReader.Close();
// Display the response.
Response.Write(strResponseData);
}
It logs me in successfully but when I click on any link, it logs out.
Please let me know what's going wrong.

From Your code it looks like you are login from other side,
What you need to do is when you login successfully you need to set session values,
And when you go to other page check this value so you will not log out.
hint is when you sent login successfully response from other site, send some values like 'userid',
and set this id session value.
