Hi Why u r saving image into database save the image in folder
on hard drive and save only image name and type into database.
Saving image into database is not a good practice.

I think that the code will be depended on the EMail Server that you used. For example, if you are using Microsoft Exchange Server, you can find the code about how to manipulate the MS Exchange server.

To create a website like yahoo or gmail or any large website, it's not that easy. I suggest you to start with small application and read more about ASP.NET and the different kind of Exchange Servers. Once you got the solid idea, you can develop those kinda site..

Hi to all,

I m newbie to asp.net Sleepy | :zzz:

n its my first site which i m trying to develop (asp.net(vb)) but i m facing the tab index problem to navigate cursor to the next text box. Mad | :mad:

In my login page first focus in on user name but when i press tab again n again first it goes to the controls of top.ascx which is used in every page of my site n then goes to the addressbar n then come back to the password textbox. Poke tongue | ;-P

i fixed the TabIndex property 0(username) n 1(password)

In vb.net i use TabStop property to restrict the focus on control but i don't know how to do it in asp.net

Any help would be appreciated
I m looking forward to your suggestion

Thanks with anticipation Rose | [Rose]

I have a database with some fields,along with this fields an image field with datatype image is tehre.But after saving all details into the db.the saved data will be displayed on a grid.But whn i tried to retrieve the data by selecting into a grid row the text fields are coming properly.But the image will be displayed only the first photo that i uploded.Only one image will be displayed for all the rows.What is the reason I attach the image retreival code in the rowcommand of the grid.

DataTable dt = new DataTable();
dt = insunit.GetUnit(id);
Img_Logo.ImageUrl = d.Rows[0]["UnitLogoPath"].ToString();

The Getnit() is to retriving data from the table..

Hey you hav to use for loop for this..
Try this..........
DataTable dt = new DataTable();
dt = insunit.GetUnit(id);
for(int i=0; i< dt.row.count; i++)
{
Img_Logo.ImageUrl = d.Rows[i]["UnitLogoPath"].ToString();
}

it will be work...
Bye Bye.

Hey what you have done here ??
Can you try to figure out ?

DataTable dt = new DataTable();<br />
dt = insunit.GetUnit(id);<br />
Img_Logo.ImageUrl = d.<big>Rows[0]</big>["UnitLogoPath"].ToString();

Here you are taking only first rows value... Smile | :)

Change it..
If possible bind data in RowDataBound Event of gridview.
On every row find appropriate data and bind it properly.
