.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?!
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.
[code]It is for ASP.NET, i want to run it in Windows Application. I get an error says FileUpload reference doesn't exist or so. FileUpload resides in System.Web.UI.WebControls which doesn't belong to Winforms family.Please note that the file will be saved from desktop to remote file server (not ~/Uploads).
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.

I have deployed my Website on Windows Server 2007. in IIS..I have added asp:FileUpload control..i have set <httpRuntime maxRequestLength="60000"/> under the <system.web> in my Web.Config file but website doesn't allowed to Save the the file of maxlength as specified in web.config file.
I'm setting up a program that displays a website that has a FileUpload object.I wanted to have my program set the default path for the FileUpload object but I can't seem to get it to work.[code]It doesn't seem to be working, however.Does anybody how I can get my desired result?
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 tried to control another application to automate a process we do 100 times a day. It is simple enough, a few key strokes is all but I have been foiled in all attempts
I have an ImageButton and a FileUpload controls in a child page of a master page. I would like to achieve something like when user click on the ImageButton, the browse file window will pop-up like what we did when we click on the Browse button of the FileUpload control.How can call the browse file window of the FileUpload control when i click on the ImageButton?
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:
I am trying to add a fileupload control to my aspx page so the user can add pictures, but when I am implementing the code behind on VB the fileuploader controler is not recognized. I have this on aspx page inside a formview:
I have embedded the WMP control in my Visual Studio 2010 app which works on windows 7 (Framework 4.0), but installing the app on winXP, I get the following error:
System.IO.FileNotFoundException: Could not load file or assembly 'Interop.WMPLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. File name: 'Interop.WMPLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].
I guess this is a reference issue, but I have added references to WMP libraries (axinterop.wmplib.dll and interop.wmplib.dll). The WMP works on the XP machine, but not when called from my application.I have searched the web now for 5 days and changed references, and reinstalled the media player on the XP machine, but nothing works.
I have developed a Windows Service in VB.Net (VS2010) which is running on Windows7. I am trying to get "MainWindowTitle" for processes thru their process object but it returns empty.
I have 2 functions for opening and closing Windows Explorer, which is still working fine with Windows XP and even Vista. The same functions not working on Windows 7. Following are the functions:

It is possible to create windows service using windows form control in vb.net. give me the url or links. The windows forms control such as, Timer control, list-box, notify-icon control etc.
Can someone please show me an example of how I would start a timer when viewing another window such as Mozilla Firefox? I would prefer it be started with a keystroke.
I'm using Visual Basic 2008 and I've written a very handy little app that takes care of serveraladmistrative tasks when our company gets a new project. I won't get into all the features but one of the tasks that it performs is setting up a new projectolder structureon our file server with a predefined set of subfolders and it also sets userpermisions on the subfolders.nder Windows XP it worked great and saved me tons of time. It made me giggle everytime I used it in the past becuase it would save me so much time doing these simple but time consuming tasks.
Now my computer is a Windows 7 Pro machine and the only way I can get the exe to run is to right-click the .exe and choose RUNAS administrator. I'm already a domain administrator so why I would need to do this is silly and annoying. In my code I already included a RunAs_Impersonator class so that anyone could use the app which worked great until windows 7.The RunAs_Impersonator class that I use can be found hereI recently needed to make some additions to the program'sbut when I try to debug itwhen it gets to the portion of trying to create the folders on the server,the program breaks and makes claims that I don't have the rights to do so.
I have an old 32bit vb type app and we're running it on windows 7 64bit sp1. On one computer it works fine, on another it doesn't work right. Do you know how we could debug this and figure out what's causing it? Could a different CPU or bios/chip set have something to do with it?
This is the thing we're using specifically:[URL]...
I am using Visual Basic Express 2010 and the AXwindowsmediaplayer PlayStateChange event does not appear to work in Windows 7. I put a break point in my code and can start, stop, pause the player and the event is never initiated. If I run this in XP or Vista it works. I even started a new project in VB express on the Windows 7 machine with nothing but a player and the event and it is never initiated. is there a work around for this? i have set a timmer but the event I am watching for, MPLib.WMPPlayState.wmppsMediaEnded, happens so quickly that the timmer never catches it
I have an application that I want to load using the scheduler in windows. I am also wanting the "enter" key pressed when the app loads. Because you cannot use a batch file I tried using a vb app. It works great on two different windows 7 machines but not at all on the xp machines. The xp machines load the app but don't follow through with the sendkey.
Sidenote - I had to repeat the sendkey function in order to get this to work because I am not sure how to use the sendkeys.sendwait function. I tried and it never worked.

I am working with Visual Studio 2010 Pro. My OS is Windows 7 x64.I am migrating a VB.NET application that was written for .NET 1.1 / 1.0 in a much earlier version of Visual Studio.The project converted without many issues and works except for on thing. The Jet 4.0 libraries are not available for Windows 7 x64. I understand that they have been replaced with ACE Provider, with actually has an x64 version.
I need to be able to manipulate an MS Access 2003 format database (MDB). I am planning to target .NET framework 2.0 to ensure maximum compatibility with downlevel clients. (I can't install framework 3.5 or 4.0 on these machines). I need to continue supporting MS Access 2003 format on these machines. If I switch to the ACE provider, wouldn't I have to at least install the Microsoft Office 2007 data access components on all of the machines that will run this application? What's the best way for me to target these older machines without having to install any extra software? They already have .NET 2.0 installed and have the JET 4.0 libraries registered.
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?
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:
