Thanks Richard and Shan,
I am using the HtmlInputFile control.But Shan where
exactly do you want me to put in your code? becoz,after
the user selects a file to upload and hits Submit, then
the flow of the code does not go into the OnClick() event
of the submit button, if the filesize is > 50 Mb.I checked
this by setting a breakpoint on the first line of the
OnClick event. The aspx page just shows a DNS error page.
Is there a way, that i can check the size of the file
before the user clicks submit maybe. -----Original Message----- Assuming you use the HTMLInputFile Control to choose your file to upload then you can do something like this,
HttpPostedFi le file = fileUpload.Post edFile; int fileLen = file.ContentLen gth;
fileUpload is the HTMLInputFile control name ...
Thanks, -Shan
-----Original Message----- I am trying to upload a file to the webserver through my asp.net application. The file upload works fine for
filesbelow 50 MB size because i have set the maxrequestlengt h property of the <httpruntime> in the machine.config file as 51200KB. whenever the user tries to upload a file whichis more than 51200KB then, a blank page with DNS error
isshown as soon as the user hits the submit button. I want to be able to display an error message to the
userif the file size is greater than 50 MB. How do i catch this error? I have tried using the try catch block in
thesubmit button onClick() event, but no use. Please post
medetailed answer. Thanks in advance. 3 2277
Try to catch the exception in the Application_Err or event handler in
the global.asax file
Code:
=====
Dim AppEx As Exception = Server.GetLastE rror()
If AppEx.Message.C ompareTo("Maxim um request length exceeded.") = 0 Then
'this is an overlimit upload
'clear the error out
Server.ClearErr or()
'redirect to my error page
Response.Redire ct("errorpage.a spx")
End If
Please let me know if this works for you.
Thank you,

Thanks John. The code does go into the application error
event during debugging, but does not redirect the page to
the error page. i tried ALL three methods i.e.
response.redire ct, server.transfer and server.execute. But
the error page is not displyed. My error page has just one
label on it which says " Error occured in file transfer" .
It still shows the DNS error page.
Please shed some light on this if u can. Thank you. -----Original Message----- Try to catch the exception in the Application_Err or event

I have compiled some code, some written by me, some compiled from
various sources online, and basically i've got a very simple flat file
photo gallery. An upload form, to upload the photos and give them a
caption, storing the caption and filename in a text file. It's a bit
buggy when removing the photos and captions from the file, and also in
displaying them on the delete page. you can see it in action at

I have an upload file input as:
<input id="MyFile" style="width:300px" type="File" runat="Server">
This works fine, but I find that if my page doesn't pass validation during
postback, the page comes back with all the data intact, except for the
upload object. The text box for "MyFile" (my example) is always cleared.
Why is that and is there a way to stop that from happening?
Thanks,

I used forms based .NET authentication, although I'm also setting some
session variables when people login.
However, I've found when people use one of my webform pages which includes a
button that pops up a window where you can upload files, if you upload files
in this popup window, it seems to somehow clear out all of the session
variables and the users get logged out. However, if...

Hello,
I am trying to do a FTP file upload which works fine on my localhost but on

specific cause of the failure. In both cases the file is being transmitted

file size or login credentials problem. Could someone please help me out and
give me some ideas what is wrong.
