Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

I have downloaded application from code project.
Its giving error like
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS

How can i clear this problem?

hi,
U can use instance of Bitmap class like this
Bitmap b = new Bitmap(...)
ans use public Save method to save image with format ImageFormat.Gif

and if u want to resize image , try this code , hope it help

public Size CalculateDimensions(Size oldSize, int targetSize)
        {
            Size newSize = new Size();
            if (oldSize.Height > oldSize.Width)
            {
                newSize.Width = (int)(oldSize.Width * ((float)targetSize / (float)oldSize.Height));
                newSize.Height = targetSize;
            }
            else
            {
                newSize.Width = targetSize;
                newSize.Height = (int)(oldSize.Height * ((float)targetSize / (float)oldSize.Width));
            }
            return newSize;
        }

the oldSize param is old size of your image
the targetSize param is new dimension you want to resize to.

Hi,

As i have downloaded a small asp.net ajax project and i added this project to my visual studio 2005 and when i execute the project the error message "object reference not set to an instance of an object". and also i modified the connection string.

Debug the code.And check the line of code from that you are getting this error and it would be helpful if you put your piece of code here.

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.

How to instantiate C#.NET class at client side (inside javascript ).

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,

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.
