Uploading a photo and submitting form data

STEVE.com — Wed, 09 Dec 2009 05:00:00 GMT

I have a database that I would like users to be able to submit data to. My website is photo sharing site and I also want users to be able to upload a photo. I'm using a formview for users to submit the information (for the photo) to the database. I then use a FileUpload tool with the following background script, unfortunately when I run the site it tells me that the FileUpload1 does not exist.

<%@ Page language="C#" masterpagefile="master.master" title="You are about to upload a photo" %>
<asp:Content ID="head" runat="server" ContentPlaceHolderID="head">
<script runat="server">

    protected void UploadButton_Click(object sender, EventArgs e)
    {
        // Save the uploaded file to an "Uploads" directory
        // that already exists in the file system of the
        // currently executing ASP.NET application.
        // Creating an "Uploads" directory isolates uploaded
        // files in a separate directory. This helps prevent
        // users from overwriting existing application files by
        // uploading files with names like "Web.config".
        string saveDir = @"\data\uploads\photos\";

        // Get the physical file system path for the currently
        // executing application.
        string appPath = Request.PhysicalApplicationPath;

        // Before attempting to save the file, verify
        // that the FileUpload control contains a file.
        if (FileUpload1.HasFile)
        {
            string savePath = appPath + saveDir +
                Server.HtmlEncode(FileUpload1.FileName);

            // Call the SaveAs method to save the
            // uploaded file to the specified path.
            // This example does not perform all
            // the necessary error checking.
            // If a file with the same name
            // already exists in the specified path,
            // the uploaded file overwrites it.
            FileUpload1.SaveAs(savePath);

// Notify the user that the file was uploaded successfully.
UploadStatusLabel.Text = "Your file was uploaded successfully.";

        }
        else
        {
            // Notify the user that a file was not uploaded.
            UploadStatusLabel.Text = "You did not specify a file to upload.";
        }
    }

DiscountASP.net upload control

mattcase — Sun, 15 Nov 2009 05:00:00 GMT

I have my site hosted with discountasp.net and I have a webpage that allows my users to upload their photo to their page. My problem is that when I try to upload a photo, it seems to upload correctly and gives me the confirmation that it did upload. However the file is not there.

Can anyone here help? I have already tried the discountasp.net forums.

Thanks.

FileUpload to MS SQL database

mattcase — Sun, 15 Nov 2009 05:00:00 GMT

I have been having trouble getting my page to upload a file to my discountasp.net hosting account, so I have decided to direct the uploads to a SQL database (thinking that would help solve my problem).

Does anyone know how to code that? I have placed my current code below:

FileUpload not working in EditTemplate of DataList

alisubhani — Sun, 01 Nov 2009 04:00:00 GMT

Hi,

I have problem in uploading file using Fileupload in Edit-Template of DataList.

There is no scriptmanager on the page, no Ajax and no update panel.

When onUpdateCommand is called, I put response.write to display Fileupload.HasFile and it displays False.

I cannot understand why it is happening as I am alos not using any Asynchronus postback and Ajax panels.

Code example:

<asp:DataList Id="myDataList" runat="server" onUpdateCommand="update_comand">
   <EditItemTemplate>
        <asp:FileUpload id="uploadFile" runat="server"/>
         <br/>
         <asp:Button Id="uploadButn" runat="server" CommmandName="Update"/>
   </EditItemTemplate>
</asp:DataList>


//=============== code behind ====================

protected void update_comand(Object source, DataListCommandEventArgs e)
{
        Response.Write(
                        ((FileUpload)e.Item.FindControl("uploadFile")).HasFile.ToString() );

}

Adding Outlook 2007 items via file upload

bfancett — Thu, 22 Oct 2009 04:00:00 GMT

I am looking for a way to be able to attach an Outlook item (an email message) in an ASP.NET 3.5 application. Similar to when in Outlook and sending an attachment, you can select either a file, or an item. Selecting an Item, opens up your Outlook folder directory, and you can select an email message, and send it as an attachment.

I have a need for being able to access these emails in the Outlook folder directory and add them as a file attachment. I am not using the File Upload Control, I am using an HTML input tag with type="file".

Please let me know your ideas.

Thanks!

FileUpload size validation

zautashvili — Sat, 17 Oct 2009 04:00:00 GMT

Hi,

I'm trying to validate uploading file's size, I know it's possible to check FileBites and compare it to some value, but the problem is, I'm not doing this for file size restriction in general, but because of low internet speed (browser just hangs when file is more than 20mb).

As said above, I've already tried to check FileBites, but the problem remained the same, seems like server needs to fully initialize the uploading file and then it has all the information on it and this process takes the equal time, so, browser hangs again, before the server checks the file size.

Is there any workaround for this issue?

Many thanks

FileUpload empty after validation

Ozhan99 — Wed, 14 Oct 2009 04:00:00 GMT

well the title says everyting.

I have a page with 20 TextBox's and 10 FileUpload's. On the TextBox's I've a RequirefieldValidator (server side validation).

When one textbox is empty and all other controls all filled in (also the FileUpload's) and the user Submit the form, the validation goes off and all the FileUpload controls are empty and the Textbox's not.

I know this is because of the security of IE, but is there a solution for this problem? A solution that is not the "gmail" style.

Thanks in advance.

Asp.Net(vb.Net) FileUpload Control

bmdfarooq@live.com — Wed, 16 Sep 2009 04:00:00 GMT

Hi,

I have a FileUpload control in top half of the web page through which i will be uploading the files.
The list of uploaded files will be displayed in a gridview in the bottom half of the webpage.

For the selected row in the gridview, i am populating the details in the controls in the top half of the webpage. The problem is i am not able to keep the selected row file path in the file upload control.

Can any one suggest how can i handle this problem (either through file upload control or (textbox + SaveFileDialog) controls or any other best option).

Upload 200MB+ .zip files

CurtWRC — Thu, 10 Sep 2009 04:00:00 GMT

Hi,

I need to find a way of uploading a very large zip file through my website.

However, if I'm to do a simple upload through the asp:FileUpload control using FileUpload.SaveAs() as I'm concerned this will take to long to process, and may time out the server. I'm aware I can just increase the time out length, but to be honest I don't want users to have to wait minutes if its possible

Is there some way the user can upload the .zip file, but then are redirected to another page stating that the file is currently being uploaded and that they should not turn off their computer.

Thanks!
Curt

Re: FileUpload loses file on submit

realfantasy — Mon, 24 Aug 2009 04:00:00 GMT

fileupload control can't keep path after postback...

you simply create hiddenfield and on button click call javascript function and get value of fileupload control and put in that hiddenfield.

and on window.onload .. simply put back to asp file upload control
