I think this code will work just try it. And let me know it's working or not just change image format as per requirement and variable name and also that database fieldname.
Response.Clear();
Response.ContentType = "image/jpeg";
System.Drawing.Image image = null;
Cmd = new SqlCommand("SELECT fieldname FROM tablename where field='" + id + "'", Con);
Cmd.CommandType = CommandType.Text;
SqlDataReader Dr = Cmd.ExecuteReader();
if (Dr.Read())
{
byte[] imageData = (byte[])Dr[0];
MemoryStream memStream = new MemoryStream(imageData);
image = System.Drawing.Image.FromStream(memStream);
image.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
}

Hi All,
I involved in developing a small web site. I need to filter Questions and it's answers from DataBase into asp.net pages, every page contains just 3 Questions and it's answers, and others questions will be filtered into new pages generated automaticaly according the number of Questions in the database. I need some tips or any idea or topics talking about this.
all Regards
Mr.Wonderful

Why do you need to create different pages? If you are developing with ASP.NET 3.5, you could use a ListView with paging support to display questions in groups of 3 and allow the user to navigate between the groups of questions using standard paging controls.

He didn't specify which version of the framework he was using. In the absence of this information, I would have to assume he was using the latest version, i.e. v3.5.

Wait a minute guys, don't bother. I didn't determine which version of framworke I used, because I Suppose 3.5 a new version, and many Developers (maybe) still doesn't used it including me. I still using Version 2. anyway this is a task assigned to me not my option, so if we say create panels at run time and filter just 3 Questions and it's answers into panel that will be created according the numbers of questions in run time with 2 buttons Next And Previous to navigate between panels.
by the way, how we can make these buttons appears in each panel and take this answers(I mean take it's value True or False when clicking on the next button, I determine in the database the right answer), maybe we talking here about QueryStrng or similir, any help please.
thanks in advanced

You what they say about assuming.
If you are in the business you know that the vast majority of development shops have not taken up 3.5 yet.
BTW, very mature to vote down the posts because they point out your deficiencies.

Like I said, the OP didn't specify which version of the framework he was using. I suggested that if he was using v3.5 of the framework he could use the ListView control. This was intended to open a dialogue with the poster, where I could have explored other options if he wasn't using this version.

I didn't vote down the posts, and I resent the accusation that I did. Maybe I'm not the only one guilty of making assumptions  .

You could use the same control, say a Panel, to insert the text as needed. You don't really need to create separate pages.
BTW: This doesn't require 3.5

If you look at the source for this page, you can see that the showing/hiding of controls is done using javascript. Just download the .js files referenced in the page if you want to understand how the code works.

Hi Friends,
I new to vb.net. In c#.net in GridView i use RowDataBound method and make a check if commandname is Delete i catch the linkbutton(Delete) by FindControl and on Click i give javascript method for Confirm. If Ok it goes to RowDeleting else Cancel.
I am trying something same in vb.net for DataGrid.
The button in DataGrid is
<asp:ButtonColumn Text="??a??af?" ButtonType="PushButton" CommandName="Delete"></asp:ButtonColumn>
Any idea how can Throw a Confirm Message on Click of This button?
Any help would be greatly appreicated
Thanks
Cheers

VB.NET is just like C#, except for the lack of ; and more verbose, and less challenging 
In either case, rather than requiring a postback to inject javascript code into the page to display a confirm dialog, you could just use a template button to contain a simple button control and specify the javascript.
<asp:Button runat="server" onclick="return confirm('Do you want to delete?');">

I am working on a product that has ~ 30 web pages. Each page has
various number of controls ( between 20 - 40 controls that include
gridview, text boxes, combo boxes etc). This product should have
ability to connect to different type of data sources ( Oracle, SQL
Server, mySQL etc). I am using ObjectDataSource to populate controls
on these pages. I am trying to minimize back and forth communication
between the pages and backend database. I have createad stored
procedure that will gather all the data required on each page (meaning
one stored procedure per web page that give data needed by all
controls on a given web page). I am wondering what is the best way of
displaying this data by splitting rows return from stored procedure in
the ObjectDataSource. Any links, code examples or hints will be higly
appreciated.
TIA

You have been around here long enough to know that reposting the same question draws the ire of everyone here. Saying it is repost is helpful for us to ignore you.
The same goes for URGENT.

My apology for it. I didn't know that ,haven't really used these forum much. I did not want to offend anyone just am trying to get some sugggestion.

Your problem is that the ObjectDataSource is the aborted whoreson of satan. You really shouldn't use it - in any way at all. It just binds your datasource to the UI and that's bad news - you're just asking for trouble with scalability. Instead, consider separating your UI from the business layer and the data layer. This way you can have much more control over how the data is retrieved, how you page it, and so on.

MailAddress toEmail = new MailAddress(to);
System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage(fromEmail,toEmail);
