Hi all,
I googled a lot and found that to display images from database we need to fetch it from DB and
Convert it to Byte[] and then pass it to Response.BinaryWrite() method.

But this is not working for me.

Can anyone please help me wid this?

Thanks & Regards,
Pramod

Session Problem (Login View wrong display)

You need to create the image from byte array.
use a temporary folder to create the image.

byte[] image = GetImageDataFromDatabase();
string imagepath = Path.Combine(Path.Combine(Request.PhysicalApplicationPath,"tempImages"), "imagename.jpg");
using (FileStream ofstream = new FileStream(imagepath, FileMode.Create))
{
      ofstream.Write(image, 0, image.Length);
      ofstream.Close();
}
imgobj.src= "tempImages/imagename.jpg";

This will work. Rose | [Rose]

Hi all,

In a ASP.NET website, I have used Login View to show the Login Status. For Login I have used Login Control.
It is showing status correctly. But after few idle minutes, it is automatically login view text changing to "login"
But user is already logged in. I think this is Session problem. I have used below line earlier. I commented it now.
Still same problem.

<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="UseCookies" timeout="1400" />

pl.help me out

Cookies not working

Hi,
Just a small code to check whether cookies are getting stored/retrived or not.
Check the code below:

protected void Button1_Click(object sender, EventArgs e)
{
Response.Cookies["userName"].Value = "patrick";

}
protected void Button2_Click(object sender, EventArgs e)
{
if (Request.Cookies["userName"] == null)
Label1.Text = "Cookie not found";
else
Label1.Text=Server.HtmlEncode(Request.Cookies["userName"].Value);

}
------------------------
When I try to retrieve the cookie values on button2_click, it is not retrieved although I have set the option "accept all cookies" in IE 6.
Where is issue?

Is this happening between postbacks.
I think it should work if you are not working cookieless.
I checked and found working. Confused | :confused:

Also check whether you have re initialized the value on page_load section.

I have not written anything in page_load.
Just this small code.

Moreover, when i try to see cookies folder, no such cookie is there.

I am running this web page on my machine only i.e. no webserver, just a local host.

The above code is working now.
IF i write the below:
Response.Cookies["userName"].Expires = DateTime.Now.AddDays(1);

There could be any value of expiry.

Why is it mandatory? I mean if we donot set it, does it mean it will not create at all.

Moreover, without seeing the code, how to verify the expiry time of a cookie?

How to Open new aspx page in same window

13-Sep-09 21:29

Well... what you can do is create a session yourself in the database based on the IP of the machine and assign each session state to the same IP.

If you map using IP, it will be easier to handle this. Smile | :)

The function is CALLED window.open, what did you expect ? Why do you need a method instead of just using a link ? Oh, because it's in response to a dropdown. Use window.location.

I think it is not available in most of the browsers ... It is IE specific. Not in w3 standard function list. Frown | :(
