I have gotten FileUpload in VB.Net to work fine in saving a file to a web server folder but cannot find some examples on how to save the file as an image on sql200. Can anyone point me in the write direction - thanks.
View 3 RepliesI am trying to use the FileUpload control to save a filename to a SQL database. I'm using the OnUpdating event for my SQLDataSource to add the filename to the UpdateParameters. The OnUpdating event is firing but the FileName doesn't get added to the database. Any pointers as to why that might be would be very helpful.
Here's the code. Thanks much.
<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="File Upload Testing" %>
<script runat="server">
Sub Page_Load()
Response.Write("UpdateParameters(0)=" & dsLabel.UpdateParameters(0).Name & "<br />")
Response.Write("UpdateParameters(1)=" & dsLabel.UpdateParameters(1).Name & "<br />")
End Sub
Sub dsLabel_OnUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs)
Dim FileUploadControl As FileUpload = DetailsView1.FindControl("FileUpload1")
Dim strFileName As String = FileUploadControl.FileName
dsLabel.UpdateParameters(0).DefaultValue = strFileName
dsLabel.UpdateParameters(1).DefaultValue = Request.QueryString("rgstnID")
Response.Write("dsLabel.UpdateParameters(0).DefaultValue = " & dsLabel.UpdateParameters(0).DefaultValue & "<br />")
Response.Write("dsLabel.UpdateParameters(1).DefaultValue = " & dsLabel.UpdateParameters(1).DefaultValue & "<br />")
End Sub

I have a project that is using an exsisting SQL DB that stores uploaded files and images into the DB.
I am trying to figure out how to take the file from the fileupload control and place it into the DB field.
Almost all the examples I've seen deal specifically with images but I will not know what the file type is. It could be an image, a word doc, and excel file, a text file ect.
I thought to use a INSERT statement but I wonder if that will work.
I know that fileupload.postedfile.saveas saves the file to a directory you name but that does not help me. I thought I could just use the fileupload.contents property in the Parameter add statement but that must not be an option as I cannot find and example of that usage besides that would just be too easy I guess.
Any help or code would be accepted with great gratituide. I realize that this is not the best way for performance but it is what it is and I cannot scrap the old DB I just have to make it work.
Thanks,
Ty
Hello,
I have a FileUpload control on my webform. I would like a user to be able to upload a file to the server. Is there any way to store this file in SQL Server 2005?
Thanks

HiHoping someone can help me , I am looking to add a file upload inside a createuserWizard but am banging my head at this stage I can get in working saving the file selected in the Fileupload into a table on the database using a datatype "image" for the field.However
ideally I would like to save a string of the file path to the database
and save the actual file to the filesystem of the webserver.The
problem for me is that this is inside a CreateUserWizard, I gather the
standard information and them have "extended" the wizard by adding
another wizard step , which will include a FileUpload control. I need
to invoke the FileUpload when the user select the createUser button of
the CreateUserWizard control( CreateUserWizard1_CreatedUser in the aspx.cs) I
am able to write the SQL that allows save information from a textbox
to a database tabel but not able to write the functionality to 1.Uplaod file to webServer when user selects Create User button 2. Save this path in a table on the database.I've tried loads but cannot get it to work I'm using C# for this. here's a scaled down version of my code with just teh CreateUserWizard which contains the fileUploadaspx ( Contains a create user Wizard which inturn contains a Fileupload) <%@ Page Language="C#" AutoEventWireup="true" CodeFile="FORUMcreateuser.aspx.cs" Inherits="_Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head id="Head1" runat="server"> <title>Sign Up Page</title></head><body> <form id="form1" runat="server" enctype="multipart/form-data">

Hi
I have a asp:FileUpload conponent that I am trying to use to retrieve a picture file from the clients pc and store it in a SQL database.
The table is called PropertyImage and it contains the following fields:
imgID (type = int - autoincrement); imgData (type = Image); imgTitle (type = VarChar); imgType (type = VarChar); imgLength (type = BigInt);
I have a button (Button1) which when clicked calls Button1_Click()
--------------------------------------------------protected void Button1_Click(object sender, EventArgs e)
{byte[] fileData = null;
Boolean status = false;if (FileUpload1 != null)
{
// Make sure the file has data.if ((FileUpload1.PostedFile != null) && (FileUpload1.PostedFile.ContentLength > 0))
{
// Get the filename.string fn = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
try
{
// Access the file stream and begin the upload. Store the file in a memory byte array.Stream MyStream = FileUpload1.PostedFile.InputStream;
long iLength = MyStream.Length;fileData = new byte[(int)MyStream.Length];MyStream.Read(fileData, 0, (int)MyStream.Length);
MyStream.Close();
}catch (Exception ex)
{ }
}
}SqlConnection connection = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\heidihomes.mdf;Integrated Security=True;User Instance=True");
try
{
connection.Open();SqlCommand sqlCmd = new SqlCommand("INSERT INTO PropertyImage (imgData, imgaTitle, imgType, imgLength) VALUES(@data,@title,@type,@length)");
SqlParameter param = new SqlParameter();
// String connectionString = new SqlConnection(sqlCmd, connection);
param = new SqlParameter("@data", SqlDbType.Image);
param.Value = fileData;
sqlCmd.Parameters.Add(param);param = new SqlParameter("@title", SqlDbType.VarChar);
param.Value = fileData;
sqlCmd.Parameters.Add(param);param = new SqlParameter("@type", SqlDbType.VarChar);
param.Value = fileData;
sqlCmd.Parameters.Add(param);param = new SqlParameter("@length", SqlDbType.BigInt);
param.Value = fileData;
sqlCmd.Parameters.Add(param);
sqlCmd.ExecuteNonQuery();
connection.Close();status = true;
}catch (Exception ex){ }if (status)
{
UploadStatus.Text = "File Uploaded Successfully";Server.Transfer("Admin_PropertyView.aspx");
}
else
{UploadStatus.Text = "Uploaded Failed";
}
}
}
--------------------------------------------------
But when I click on the button, nothing happens.
Please could someone help me out here. I have tried this a few times and still haven't come right.
Also, if there is something else wrong with the code, please let me know.
Thanking you in advance.
I am almost done with a simple page to have a user select a file (using the FileUpload object), give it a short description and associate it with an item from a listbox. Thensave these pieces of data to a new row in a SQL DB.
My issue...
The SQLSmd.ExecuteNonQuery FAILS...
I have got all the fields able to connect and almost save... but for the actual "document" field errors out. The user can select any type of file (image, word, excel, Powerpoint, etc) for storage into the DB. I am not storing a referance to a file or the path to a file but the actual file in SQL.In the DB I have the field (Document) set to a type of VarBinary(8000) in the table. Here is thethe corrisponding code in my app...
Dim bArray As Byte...bArray = FileUpload1.PostedFile.InputStream.ReadByte()... SQLCmd.Parameters.Add("@Document", Data.SqlDbType.VarBinary, 8000).Value = bArray...iReturn = SQLCmd.ExecuteNonQuery()
ERRORThe first section of the stact trace...
[InvalidCastException: Invalid cast from 'System.Byte' to 'System.Byte[]'.] System.Convert.DefaultToType(IConvertible value, Type targetType, IFormatProvider provider) +867 System.Byte.System.IConvertible.ToType(Type type, IFormatProvider provider) +37 System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) +408 System.Data.SqlClient.SqlParameter.CoerceValue(Object value, MetaType destinationType) +896
I am trying to upload a file in ASP.net 2.0 to a SQL database using the FileUpload control. I am doing this by way of a typed dataset.Here is my code.Dim rta As New ResponseTableAdapterDim rdt As ResponseDataTable = rta.GetResponseByID(1)Dim rr As ResponseRow = rdt(0)Dim fs As New FileStream(fu.PostedFile.FileName, FileMode.Open, FileAccess.Read)Dim br As New BinaryReader(fs)Dim image() As Byte = br.ReadBytes(fs.Length)br.Close()fs.Close()rr.UploadFile = imagerr.NameFile = fs.Namerta.Update(rdt)The code runs without an error but afterwards I find that nothing has been stored in the UploadFile cell in the database but the file name has been stored in the NameFile cell in the database. Any ideas?Your help is much appreciated. James
