hello friends,
i am developing an application in which i want to
upload an image from clients hard drive(local hard drive)
to the server.
i mean the application should provide the user with the
the faliclity to click on LoadPic button to open a
Open File Dialog on his/her system, then allows the user
to browse to the actually image and once the user is done,
by clicking on Send button, sends the image to the server
database.
i have SQL Server 2000 as RDBMS.
how can i accomplish this is ASP.NET ?

Drag a file field control from the HTML section of your toolbar onto your form.
Right click on it and make sure it's set to run as a server control.
Also drag a button onto your control to begin the upload.
Here's the code that goes under the button. This code will work to upload any file type, not just images.
Private Sub btnAttach_Click (ByVal sender As System.Object, _
ByVal e As System.EventArg s) Handles btnAttach.Click
Dim iLength As Integer = _ CType(File1.Pos tedFile.InputSt ream.Length, Integer)
If iLength = 0 Then Exit Sub 'not a valid file
Dim sContentType As String = File1.PostedFil e.ContentType
Dim sFileName As String, i As Integer
Dim bytContent As Byte()
ReDim bytContent(iLen gth) 'byte array, set to file size
'strip the path off the filename
i = InStrRev(File1. PostedFile.File Name.Trim, "\")
If i = 0 Then
sFileName = File1.PostedFil e.FileName.Trim
Else
sFileName = Right(File1.Pos tedFile.FileNam e.Trim, Len(File1.Poste dFile.FileName. Trim) - i)
End If
Try
File1.PostedFil e.InputStream.R ead(bytContent, 0, iLength)
With cmdInsertAttach ment
.Parameters("@F ileName").Value = sFileName
.Parameters("@F ileSize").Value = iLength
.Parameters("@F ileData").Value = bytContent
.Parameters("@C ontentType").Va lue = sContentType
.ExecuteNonQuer y()
End With
Catch ex As Exception
'Handle your database error here
dbConn.Close()
End Try
Response.Redire ct(Request.Url. ToString) 'Refresh page
End Sub
Here's the SQL Query that the above code uses:
INSERT INTO tblAttachments
(FileName, FileSize, FileData, ContentType)
VALUES (@FileName, @FileSize, @FileData, @ContentType)

Hello All,
The problem with File1.PostedFil e = Nothing can be resolved by adding adding "enctype" to your form like so:
<form id="Form1" method="post" runat="server" enctype="multip art/form-data">

I've got a PHP Upload Form that works great, unless that is, the image
your uploading has been modified through a photo editing software.
Example: if I upload the image straight from a camera or other, it
uploads fine. However, If I want to rotate the image, or resize it
with photoshop or simmilar, making sure to save it again as a jpg, the
PHP upload won't upload the image.
