Asp.net - FileUpload Within A Wizard Control, Processed At The End

Oct 17, 2011

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

[Code]....

ASP.NET/.NET FileUpload Control?

Apr 28, 2011

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

My FileUpload Control Freeze

May 22, 2012

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.

.net - FileUpload ASP.NET Control Not Working Under Windows 7

Apr 28, 2010

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?!

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?

Asp.net - FileUpload Control Inside Gridview (ajax Updatepanel)?

Mar 11, 2011

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?

Method Of Using A Tab Control To Act Like A Wizard?

Oct 27, 2009

I am new to VS and evaluating VS 2010. I am trying to create a wizard type control, on which various controls are on each tab. I then want to turn off the tab description and outline and control which tab controls are displayed by programmatically selecting each or one specific tab. Also require to be able to place a control above a tab (not on any of the tabs, which will mean that the control is visible whenever the form is displayed

I am trying to duplicate the characteristics of the Clarion (Soft Velocity) language tab control.

I have noticed that the tab control does have a "visible" attribute and if turned off that none of the tabs are visible. I guess what I need is a "visible" attribute (most probably inhereted from the parent tab control ) which can be programmatically changed.

I have been asked to build a custom wizard control in VB.NET for a windows forms project. It has been made very clear to me that I am not "allowed" to utilize existing wizard controls on the internet due to some obscure logic surrounding copyrights. It has also been made clear to me that we are not "allowed" to use usercontrols in the software.

Android - ASP.Net Wizard Control On A Mobile Browser

Jul 25, 2011

We are using a .net wizard control for a mobile website. Everything works great except on android devices when the user exits the browser to take a call or send a text message. When the user returns to out web page the android browser is refreshing the web page. Our problem is when the web page refresh the wizard is losing the view state So if they are in the middle of the wizard there previous work is lost. how to combat this. Is there a way to persist the wizard even if the user refreshes the webpage? I basically want to make my asp.net wizard control truly stateless.

Asp.net - FormView Or Not - Page With A Wizard Control Containing Several Pages Of Form Fields

May 20, 2011

I have an ASP.NET page with a Wizard control containing several pages of form fields. The data is collected and inserted to a database from the code behind page. I need to set this form up so you can not only insert, but edit a record as well. Since the form is long and complex, I would rather use the existing one and not make a duplicate one for editing, especially since I want to keep both forms exactly the same and any edits would have to be made to both. But it looks like this is what I need to do if I'm going to databind it. But this would also involve putting the Wizard inside of a FormView, and then I'd have to use FindControl to access any of the fields which would mean altering all my already-existing code (which of course would be time-consuming). So should I manually enter all the values from the code behind instead of databinding it? Which is better, to use a FormView and have duplicate forms (plus have to go in and redo the way I access the fields), or to do everything from the code behind?

Event Handlers Processed Asynchronously?

In VB .NET, when you call RaiseEvent X(), is the function that handles the event X processed asynchronously or synchronously. I was under the impression that RaiseEvent and the processing of the event were Synchronous unless created explictly on another thread. I've been told otherwise though.

VS 2008 Many Messages Sent To Server - Few Processed?

Jan 20, 2010

I'm using a modified version of John's Message server, instead of passing a string I am passing a serializable object called "DataClass".This is my modified Read sub to process data that gets sent from the client to the server:

vb.net
Protected Overrides Sub Read(ByVal ar As IAsyncResult)
Dim asyncState = DirectCast(ar.AsyncState, ReadAsyncState)
Dim buffer = asyncState.Buffer
Dim client = asyncState.Client
Dim host = Me.clients(client)

[Code]...

The message is received fine when they aren't in quick succession, however I tested it by sending like 1000 messages almost instantaneously and it only processed about 2. Obviously this isn't acceptable, but I am unsure how to properly implement some type of queue that will ensure all backlogged messages will get processed.

Check Login In MasterPage Before Any Other Code Processed

Nov 15, 2011

I'm developing an application which requires log in. I'm using Master Pages and a customer Web Control which is my main menu system. The main menu accesses database information to provide notifications and various things, none of which will work unless the user is logged in. I am trying to place the following code:
If Session("hgAdminUser") = "" And InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then _
Response.Redirect("Login.aspx") ' if userSession is empty, redirect to login page.

Into the top of my MasterPage code behind, but it's still trying to process scripts, the main problem being that it is running the .ascs file which requires Database access, which it can't do without the required parameters from Login. I've tried running it within a Page_PreInit sub, also Page_Load and Page_Init, but in all cases it ignores this (or probably doesn't ignore it, but errors come in before it deals with this) and returns a big fat ERROR due to functions that I don't even want it to be running!! How can I check for a session variable, which if not present cause all other scripts on the page to be ignored and redirect? This is all using VB.NET

I need to display on the form which directory is being processed. Similar to if we use the Debug.writeline which writes to the output in Visual Studio. I tried using a ListBox but it only displays the last one and only displays the last one once processing is done. I want to be able to display each directory name as it is being processed.[code]...

.net - ASP.NET Keep Fileupload After Postback?

Jul 13, 2010

I'm writing an intranet ASP.NET page using VB.NET. I've run into a particularly nasty problem dealing with handling file uploads. I'll do my best to explain the problem, and perhaps someone can help.

My problem is almost a duplicate of this one, or this one, except (other than the filename) I don't care about sending the file to the server until the other data has been reviewed. here's the situation:

Joe Q. Dataentry inputs some data into several fields. The first 3 are drop down, and when he changes the selection, a postback event is fired that queries a database for valid entries for the other drop down selections. After selecting the values, he inputs some other data, chooses a file to accompany the data and clicks the "Update" button. When he hits the button, it fires a postback event that sends the current data to the server to be validated. The data will create a change in the database, so he is presented with a view of the current state, and what it will look like when his changes are made. He can now either confirm or cancel the operation for whatever reason.

Part of the data he will see involves the extension of the file which may be a PDF, or could also be some image file or other document.

Now here's where my problem is - on each postback event, the fileupload dialog is cleared. I was getting around it by creating a temporary file on the first postback and then renaming if he clicks OK or deleting on Cancel... but I need to do a variety of things, based on the previous state of data and the filename. I've tried to keep some session variables to retain the filename, and that works OK for just renaming the file, but for what I need to do it gets unwieldy.

What I want to do is be able to have the postback event to present the changes, and then when the user clicks "OK", submit the file. Is there any possible way to do that?

One of my thoughts was to do some of the validation client-side (I'm already re-validating server side so I'm not too worried about data security there), but I don't know how I could get the information from the database query. It appears that what I want to do is prevent a certain button from firing a full postback. Is there any way to do that?I have an update panel on the page already - is there any way for the button to only post what's in the update panel?
