byte[] im = (byte[])insunit.GetLogo(id);
MemoryStream ms = new MemoryStream();
ms.Write(im, 0, im.Length);
Bitmap bm = new Bitmap(im);
bm.Save(Response.OutputStream, ImageFormat.Jpeg);
//Img_Logo.ImageUrl=;
public byte[] GetLogo(string Id)
{
byte[] s;
string sqlstatement = "SELECT UnitLogoPath FROM Units WHERE UnitId='" + Id + "'";

Abay Dhakan , In order to make the image appear into the image control , it is mandatory to display it in a blank aspx page and afterwards give the imageurl , the address of that page(where u have to display the image).

Wow - this is so wrong. If he saves the file to disc, he can put an image control anywhere he likes. Not saving it to disc is his core question.

The only way to do this, is to write an HTTP handler for a custom extension, which loads your image and feeds the bytes back. Otherwise, the image needs to be a file on your hard drive, not just a byte stream.

How can I detect Admin from Customer?
How Can I have two login page and how can I use "Forms Authentication" in this way. (my customers and Dmins have roles)

Your design is broken. You should have one table, of all people who can possibly log in. Then your site should support roles, and only show options to a logged in user who has permission to see them.

I have enabled deleting with a DetailsView. In the view I am displaying all the fields in a table except the primary key (a GUID). I am having a hard time writing the DeleteCommand. Using the primary key in my WHERE clause would be easiest, but where can I get it?
Is there a way to select the key, but not display it, and retrieve it as a parameter for my DeleteCommand? Is there a better/preferred way to determine the row to delete?
Thanks

What about adding one column in DetailsView? you can hide that column..

Following is the expression , that represents the trimming of the string , which has the white space.
function LTrim( value )
{
var re = /\s*((\S+\s*)*)/;
return value.replace(re, "$1");
}
function RTrim( value )
{
var re = /((\s*\S+)*)\s*/;
return value.replace(re, "$1");
}
function trim( value )
{
return LTrim(RTrim(value));
}
and am unable to understand the meaning of the expression
/\s*((\S+\s*)*)/
Will somebody please make me understand

the first \s* leaves any number of blank spaces
the inner one (\S+\s) matches one more non space characters and a space.. for example.. "asm " or "a " etc.
And the outer ((\S+\s)*) matches any number of these words..
in short, this regex breaks a sentence into words..
for ex. " My Name Is ABC XYZ"
can be extracted as "My_", "Name_", "Is_", "ABC_"
XYZ isn't captured because it does not have a trailing space and so doesn't match (\S+\s)

i was trying to figure out the solution of trimming.
i reached the following expression
function ltrim(s)<br />
{<br />
var temp = s;<br />
alert('hi');<br />
var obj = /^(\s*)([\W\w]*)/;<br />
if (obj.test(temp)) <br />
{<br />
temp = temp.replace(obj, '$2'); <br />
}<br />
return temp<br />
}<br />
<br />
function rtrim()<br />
{<br />
var temp = s;<br />
alert('hi');<br />
var obj = /^([\W\w]*)(\s*)$/;<br />
if (obj.test(temp)) <br />
{<br />
temp = temp.replace(obj, '$2'); <br />
}<br />
return temp<br />
}<br />
<br />
function trim(s)<br />
{<br />
return rtrim(ltrim(s));<br />
}
I think there is missing something.
One more thing , What is the difference between $1 and $2.
Please help

i have a better solution which i have verified as well on my many application try this.
i hope this will solve your problem
function TrimWhiteSpaces(s)
{
s=s.replace(/^\s+|\s+$/g, "");
var myArray=s.split(" ");
var outPut="";
for (var i=0;i&lt;myArray.length;i++)
{
if(myArray[i]!="")
{
outPut=outPut +" "+ myArray[i];
}
}
s=outPut;
return s;
}
wish you all the best

function rtrim(s)<br />
{<br />
var temp = s;<br />
var obj = /([\W\w]*)(\s*)$/;<br />
if (obj.test(temp)) <br />
{<br />
temp = temp.replace(obj, '$2'); <br />
}<br />
return temp<br />
}

Hi,
In my application I am using a function that is currently written in the app_code directory.
This function called GetRole() gets the role of the logged-in user from the database table.
The function is called from almost all of the pages and user controls in my application
both on Page Load as well as on the PostBack events such as the click of a button etc.
Now is it possible that I get the Users Role only once when the user launches the
application and store it across all pages in my application.
We are not allowed to use sessions. Any ideas would be appreciated.
Thanks in advance,
Aakar
