A scarry one.

I got something similiar when i was printing pdf-s from asp.net, service i used did not have enough permissions, and got similiar when there ware thread problems. But, "system.formatexception" could mean that you send wrong data type. How do you call this service? Got any code to see what you exactly doing?

Try without multiple threads for start. But i would say you call some method with wrong data type parameters.

There is very simple solution for this.

Make something like this
Now, if you add query string to image with time, it will show picture ok, since this image name does not exist in cache of browser.

Edit:
Don't worry, query string on image will not break anything. Image will show, no matter if you put it like "image.jpg" or "image.jpg?something".

There are more ways to handle this, set expire header to image in past, this will also force browser to read image from server and not local cache.

If you are using server control Image1 then bind ImageUrl property with your last image.
Otherwise show us your code and we will try to hand you.

There is no way that he would show you cached image if you would add query string to image. I do use asp.net everyday, but i don't use webforms, i write pure code with my own framework and template engine so i can not give you exact code you could make this in webforms.

Give your code after you applied what i wrote you to apply.

Now, why it shows same reason, if browser opens up image "members/member1.jpg" he will cache this image, and each time you request from same domain image from same path and file name, he will return you the one you cached. But if you cahnge image name, he will not return you cache, since you can not change image name, you can add up some query string to image, this way image name is the same, but is never read from cache if query stirng is always different. To browser "image.jpg" and "image.jpg?2343-234-234-23423-2342" is not the same thing, and this is when he starts to download fresh image from server instead of read it from cache.

Show your code you wrote after you applied what i wrote you to apply.

thanks for reply

Actualy i modify the image with same name....
my code is bellow

If Not FileUpload1.HasFile = False Then

Dim filepath As String = FileUpload1.PostedFile.FileName
Dim pat As String = "\\(?:.+)\\(.+)\.(.+)"
Dim r As Regex = New Regex(pat)

Dim extention As String = GetExtension(filepath)
If (extention = "jpg" Or extention = "gif" Or extention = "jpeg" Or extention = "bmp" Or extention = "png") Then

Dim m As Match = r.Match(filepath)
Dim file_ext As String = extention
Dim filename As String = "" & Session("abc") & ""
Dim file As String = filename & ".jpeg"

'save the file to the server
FileUpload1.PostedFile.SaveAs(Server.MapPath(".\member_snap\") & file)

Image1.ImageUrl = "~/member_snap/" + Session("abc") + ".jpeg?timestringorGUID"

Label23.Text = "Upload Successfully"

Else
Label23.Text = "Upload jepg,gif,jpg,bmp,png file"
End If
End If

This line:

Image1.ImageUrl = "~/member_snap/" + Session("abc") + ".jpeg?timestringorGUID"

This is wrong, "timestringorGUID" i wrote to explain you where oyu ahve to write Time string or GUID string, not to write this leterally, lol.

Replace the above line with this one:

Image1.ImageUrl = "~/member_snap/" + Session("abc") + ".jpeg?" & Guid.NewGuid.ToString()

Did you wrote Image1.ImageUrl = "~/member_snap/abc.jpeg?timestringorGUID"? as i wrote to you or did you put it
Image1.ImageUrl = "~/member_snap/abc.jpeg?" & Guid.NewGuid().ToString
which is what i did think you will figure out what i try to tell you.
