Using A FileUpload Control In A Website Which Should Only Be Able To Upload Images?
Jun 18, 2012
I'm using a FileUpload control in a website which should only be able to upload images. To that end, I'm checking its MIME type before accepting the upload.Does anyone know whether the FileUpload.PostedFile.ContentType property comes from the file itself or the request? The latter is insecure, since the request can be spoofed. If that's the case, does anyone know a good way to validate a file securely?

I have a problem with FileUpload, when I select a file from the local machine, it will not bring the real path of the file, it will use the path for the project files and assume the file I am selecting is there, any ideas?
Example:File name is "Q.JPG" and is in "C:" when I browse to "C:" and select "Q.JPG" and click open, I get the following Error Could not find file 'C:Program FilesMicrosoft Visual Studio 8Common7IDEq.jpg'.So when I fire up the code for Uploading the file to FTP for example, it will return an error because file doesn't exist

First off I'm using aspx pages with Visual Basic .net 2008 for the code behind.
I'm using a FileUpload control on an aspx web page to upload files to the server.
When I click on the Browse button I get a dialog box to select the file. I select the file and click the Open button and the entire file path populates the textbox portion of the control, just as it should.
However, when I use the same process to select a second file, after clicking the Open button it takes over 2 minutes for it to populate the textbox portion.

I have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'.
When the button is clicked code similar to the following is executed:
If FileUploadControl.HasFile Then
'Save the file and do some other stuff
End If
This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?!

how to upload to FTP, however when using the FileUpload control inside a Wizard control, when you move to the next step, the File you selected gets cleared because of the postback. I need to be able to rename the file according to the results from the Wizard before uploading. So...
I finish my wizard It uploads some stuff to a database Renames the file according to those results Uploads the renamed file to the FTP server
I suspect I will need to follow a procedure something like this, having an upload button next to FileUpload
On "Upload" button click stream the file to the Web Server. Complete the Wizard. If the wizard completes successfully, rename file and stream to FTP server. If the wizard fails, what? Delete the file from the web server? How?
I think I understand the process, how to split my FTP Upload function into two parts with the proper error handling for when the wizard fails.
Protected Sub UploadFile(ByVal NewFilename As String)
Dim myFtpWebRequest As FtpWebRequest
Dim myFtpWebResponse As FtpWebResponse

I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server.This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page.The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments.
So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it?
edit:Im adding some code because im still confused with this
Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
[code]....
This method gets called on a click of a button... The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />
So why is this property always returning false?
