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.

I think there is OnFocus and onBlur event for every html input control for doing this.

Hi,
I am trying to disable some items in listbox through javascipt in ASP.net
These items are disabling in IE8 but not disabling in IE6. How can I do it?
<br />
var lstRight = document.getElementById("lstSelection"); <br />
var fixedFieldIds = document.getElementById("hdnFixedFieldId"); <br />
var fieldIdArray = fixedFieldIds.value.split('^');<br />
<br />
if(fieldIdArray)<br />
{<br />
for(var i =0;i<fieldIdArray.length;i++)<br />
{<br />
for(var j=0; j<lstRight.options.length; j++)<br />
{<br />
if(lstRight.options[j].value == fieldIdArray[i])<br />
{<br />
lstRight.options[j].disabled = true;<br />
break;<br />
}<br />
} <br />
}<br />
} <br />

This is no ASP.Net question. There is a seperate Web Development [^]forum for these type of questions.
In between, IE8 and IE6 have different rendering engine. You can use IE Developer [^]toolbar to take a dig into it.

I got all available network printers but the problem is when I select Microsoft XPS Document Writer as my printer and give print Then there is an error
|
|
|
|
|
Why did you ask two similar questions ? What is the error ? It probably relates to permissions to write a file on the server.

I want to get all network printers using ASP.NET &c# and want to avid the image printer like Microsoft Office Document Image Writer or Microsoft XPS Document Writer

You can't do that with ASP.NET. Not in any way. Unless your app runs over the same network, in which case, you can, assuming your client can see the same printers that your server can.

Hello,
I am using VS 2005 and following is the code:
Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim fp As StreamWriter
Dim line As String
Dim filename As String = System.Guid.NewGuid.ToString & ".Txt"
Try
fp = File.CreateText(Server.MapPath(filename))
line = "Normal Text" & Chr(27) & "E" & " Bold Text" & Chr(27) & "F"
fp.WriteLine(line)
line = "Normal " & Chr(27) & "S 0" & " It should be superscript" & Chr(27) & "T"
fp.WriteLine(line)
fp.WriteLine(Chr(27) & "4" & " Italic Mode" & Chr(27) & "5") ' Italic mode
fp.WriteLine(Chr(20) & " or it should be superscript " & Chr(20) & "Normal")
fp.WriteLine(Chr(15) & "Girish Kumar Sharma" & Chr(18)) ' condensed mode
'fp.WriteLine(Chr(12)) ' Page Eject
fp.Close()
Catch err As Exception
err.ToString()
Finally
End Try
Dim fpforbat As StreamWriter
Dim strFilePath As String = "c:\\temp\\" & System.Guid.NewGuid.ToString & ".Bat"
fpforbat = File.CreateText(strFilePath)
Dim x As String = "Type " & Chr(34) & Server.MapPath(filename) & Chr(34) & " > PRN"
fpforbat.WriteLine(x)
fpforbat.Close()
'Dim strFilePath As String = "c:\\temp\\test.bat"
Dim psi As System.Diagnostics.ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd.exe")
psi.UseShellExecute = False
psi.RedirectStandardOutput = True
psi.RedirectStandardInput = True
psi.RedirectStandardError = True
psi.WorkingDirectory = "c:\\temp\\"
Dim proc As System.Diagnostics.Process = System.Diagnostics.Process.Start(psi)
Dim strm As System.IO.StreamReader = System.IO.File.OpenText(strFilePath)
Dim sout As System.IO.StreamReader = proc.StandardOutput
Dim sin As System.IO.StreamWriter = proc.StandardInput
While strm.Peek() <> -1
sin.WriteLine(strm.ReadLine())
End While
strm.Close()
Dim stEchoFmt As String = "# {0} run successfully. Exiting"
sin.WriteLine(String.Format(stEchoFmt, strFilePath))
sin.WriteLine("EXIT")
proc.Close()
sin.Close()
sout.Close()
'File.Delete(Server.MapPath(".") & "\" & filename)
'File.Delete(strFilePath)
My Two questions:
1.How i will get super/sub script printing ?
2.If i remove the comment from any of last two line, code do'nt run.. no printing. Why ?
Please guide me how to resolve the issue(s).
Thanks & Regards
Girish Sharma

Wow - what a nightmare this is. What are you trying to do ? Does this cause things to print on the print ? Why do you want to write code that prints stuff on the server ?
