Hi Samiullah,
this has nothing to do with the connection string. The program is missing an object, where an object is expected it is null. Check the exception details for the line in the code where the exception is thrown. This will give you a hint which object is missing.
Regards
Sebastian

Good afternoon everyone ,
I have created a class library in C#.NET.
That contains one class MyClass.
i want to create instance of this class inside javascript.
Can anybody tell me what are the necessary steps and precautions i have to take !!
MyClass.cs
public class MyClass
{
string m_filePath ;
MyClass()
{
this.m_filePath =String.Empty;
}
MyClass(string _filePath)
{
this.m_filePath =_filePath;
}
}
and the instance should call parameterised ctor.
var obj = new MyClass("c:\\"); -> what should be JS code.
Thanks in Advance........

Why you are trying this ?
If you want to pass client side variable to C# class, use HiddenField, Store values in hidden field and access from C# class from code behind .

Hai,
I have a user control in my master page,which shows the company logo based on the language selected from the dropdown in the content page,the logo comes dynamically from different language folders,I update a session variable when I change the language in the dropdown,but when I update the language the user control is not getting refreshed,only reloading the page changes the logo.
cheers,
Thomas.

Hi Thomas,
Add following code where you update the Session variable.
Response.Redirect(Request.Url.ToString());
Thanks,

Hai,
if (ddl_language.SelectedItem.Value.ToString() != "0")
{
HttpCookie cookie = new HttpCookie("viterion_app_language");
cookie.Value = ddl_language.SelectedItem.Text.ToString();
cookie.Expires = System.DateTime.Now.AddDays(365);
Response.Cookies.Add(cookie);
}
From this cookie, the session varible is updated in the master page through the init event.
The code is
HttpContext.Current.Session.Add("app_language", HttpContext.Current.Request.Cookies["viterion_app_language"].Value);
cheers,
Thomas.

if(pos=="center"){LeftPosition=(screen.width)?(screen.width-w)/2:100;TopPosition=(screen.height)?(screen.height-h)/2:100;}
else if((pos!="center" && pos!="random") || pos==null){LeftPosition=0;TopPosition=20}
settings='width='+w+',height='+h+',top=0,left=0,scrollbars='+scroll+',location=no,directories=no,status=no,menubar=no,toolbar=no,resizable=no';

Hi,
I am using WebBrowser Control and passing the url at run time.
I want to insert some text or javascript into the body of the web page being loaded in the browser.
I tried like below.
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
WebBrowser browse = (WebBrowser)sender;
if (!(webBrowser1.Document.Body.InnerHtml.Contains("Hello")))
{
webBrowser1.Document.Body.InnerHtml = browse.Document.Body.InnerHtml + "<script type='text/javascript'> var Hello; var i; var totalTable = document.getElementsByTagName('table').length; for(i=0;i < totalTable; i++) { document.getElementsByTagName('table')[i].id = 'name' + i; } function myfun() { this.style.border = 'solid 5px Red'; } function myfun1() { this.style.border = 'none'; } for(i=0;i < totalTable; i++) { document.getElementsByTagName('table')[i].onmouseover = myfun; document.getElementsByTagName('table')[i].onmouseout = myfun1; } </script>";
}
}
But, This is not working. This event is fired many times for single page.
Thanks,
Nagaraj

Hi all,
I have a problem with cookies.
I use a cookie with key/value pairs for storing articles.
I have a button "Add article" which adds a key/value pair to the cookie.
When the page reloads I need to access all the values in the cookie and display them.
the problem is that when the button is clicked the cookie is added to the Response and will not be present in the Request until another reload since - I guess - the button event handler is being executed during the page load.
If I add an article it won't show up until I do another reload on the page.
Does anybody have an idea how I can add the cookie with a button and have the value in the Request when the page loads next time.
Hope someone out there understands what I'm trying to explain.
Thank you for your help!!
