Add 3 or 4 or 5 Upload Controls and add one Button that Will do the Upload for all these Control. add a Progress Bar so that your users will know what is happening.

When you place more than one fileupload control, all the chosen files will be sent on submit of the request.

You will find each file in its file collection..

yes its Possible. Use the Upload control and set the destination of the File to your "App_Data" that is always shipped with your application or use the relative path.

Your variable strimage returns correct path?! It seems to me that isn't correctly initialized.

whats this..?
Dim strimage As String = "~/SchoolFeeCollection_lalit1/Photos/JC001924.jpg" '"~/Photos/" & photo
the easy way to find the path is to ..!
drop an image control and go to properties set the image url to the image which is stored in the folder..!and copy the path from the source which will generate by VS..!

I might be missing something blindingly obvious here but you don't need to call Server.MapPath when setting an image url. Server.MapPath will give you the physical location on the server disk which is useless when the web page is sent to the client.

Server.MapPath will return the actual physical path which wont work as an image url. If you want to generate the virtual path at run time use Page.ResolveClientUrl method instead.

Naming a file on the server in Multiuser environment.

Hello there

I've a website that allows a user to create and download a document. I first save the file in the server and then let the user download it. This works just fine. But when multiple users try to do this, they must create their own copy of the file in the server. Can somebody suggest a foolproof way of naming the file - so that everyuser downloads only their copy of the file.

Many thanks in advance.

One of possibilities is:

string uniqueFileName = Guid.NewGuid().ToString();

How about naming the file with the username as a part of it?

Or possibly a date-time-string such as 'yyyyMMddHHmmss' or a combination of the two?

Nah... What's up, Doc?

Of course.. Pad the UniqueID(Preferably a GUID) just after the actual filename. It will identify which users copy of the file it is.

Also, if your requirement is only to have a copy, why dont you use Database as file storage. It is easier to manage files in database as far as your reqirement is concerned. Only a single row with UserID Foreign key will do the job for you.

Also, another thing, if the file wouldn't be modified by each user in the server, you dont have to store multiple copies of each file.

To Resolve this you can have a Small Function that will check if the File Exists , if so tell the user else create the File. Let the user be in control of the naming. This will make things easier for them because they will remember the names. Just add a Control Mechanism to check if the File exists with that name, if it exist Suggest another name.

hi all,
on clicking a button i am getting a following error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or 
<%@ Page EnableEventValidation="true" 
%> in a page.  For security purposes, 
this feature verifies that arguments to postback or
 callback events originate from the server control that 
originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to
 register the postback or callback data for validation.

can any body guide me.......plz...

SessionPageStatePersister is not releasing the old viewstate from session and so cpu memory is running out

mtilak21-Dec-09 13:14

21-Dec-09 13:14

I have used the option of the better methods from this document http://msdn.microsoft.com/en-us/library/system.web.ui.sessionpagestatepersister.aspx[^]

PageStatePersister _pers;
    protected override PageStatePersister PageStatePersister
    {
        get
        {
            if (_pers == null)
                _pers = new SessionPageStatePersister(this);
            return _pers;
        }
    }

Everything works great, the viewstate is no longer on the page and is moved to session. But how does this get released from the session. I don't see it released and my servers cpu memory is growing indefinetely.

Thanks,
Tilak
