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

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.

Why did you ask two similar questions ? What is the error ? It probably relates to permissions to write a file on the server.

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.

Problem with code

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

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 ?

Girish48125-Jun-09 21:23

25-Jun-09 21:23

Sir,
Thanks for your reply. From the above code, i am creating a formated text file and one batch file which will be print the formated text file by using dos mode i.e. > PRN; but sir, problem is that if i wish to delete the formated and/or batch file, after run the code, i am not able to do so.

Girish48125-Jun-09 21:52

25-Jun-09 21:52

I do'nt know, how to create the text file on client's machine; and what is another way to get the DOS mode (which runs faster) printing of a text file by asp.net, so please guide/help me in this regard.

The thing Christian wants to point out is that your application will use the printer installed on the server where you application is running. It means, every time the printout will be generated by the printer installed on the server, not on the machine from where you are accessing the web page.

Girish48125-Jun-09 22:46

25-Jun-09 22:46

At the first stage if it runs on server machine and printer; then my question will be how to access and client's printer to get printout. Actually, this is running fine on server printer but if i remove the comment from any of last two line i.e.
'File.Delete(Server.MapPath(".") & "\" & filename)
'File.Delete(strFilePath)

then no print out comes on the printer.

Please help me.

Girish Sharma

That may be because the print command hasn't finished when you delete the file but it isn't important if you want to print on the client machine anyway. Look into the javascript function window.print if you need to print client side.
