Asp.net - Can't Handle An Uploaded File Exceeding Maxrequestlength
Mar 21, 2012
I'm trying to get a specific error message posted when a user tries to upload a file that exceeds the maxrequestlength of 10MB for my asp:fileupload object. However, adding the onError attribute to my fileupload object, the user does not get the error I want displayed; the page just crashes. Setting customerrors mode to on and setting up a redirect page doesn't work either; the page still crashes. How am I supposed to get the page to display a specific error without crashing?
I made a form in ASP.NET with VB background code.my problem is I want to make that the file which is been uploaded to by the form to change to "Resemey.doc" instead for example "012 MaraCSD.doc"did a bit of research and found out I need to add some code to my vb code.but couldn't find what, and where to put it.
this is my code:
'Add the namespace for the email-related classes Imports System.Net.Mail Partial Class SendAttachment
I need a snippet to check file for validity (I'm allowing users to upload xml files). So I need to check whether uploaded file is XML. The best I can think of is just check if extension is ".xml". What if its replaced?
This method will only verify the file's extension, not its actual type. Once I receive the file, I want to examine its contents to determine what it really is, in this case image only.
I am developing an application that will do 2 things:
- connect to a webservice
- Upload/download files through WebDAV.
Seems to work fine, but I am having an issue with debugging. Since WebDAV is installed on the server, i have to publish the webservices there aswell, as the webservice is going to access the file locally (serverside) after upload to the server. This makes it impossible for me to debug the webservices. When i switch to the local services for debug, they cannot reach the file that was uploaded to a remote location (the server). Is it possible to install a local WebDAV server, even if i do not have IIS set up? Just for testing purposes?
I am writing a code that downloads alot of information from different servers. Puts the information in an excel spreadsheet, saves the sheet, and uploads it to an FTP page for each server. The code is running into an OutOfMemoryException. Is there a way to clear the memory after each servers file is uploaded to the FTP?Or is there another way to fix the problem with out adding memory to the server the code is running on?
I have recently programmed a site that enables a user to upload and download files to and from an FTP site.
I now wish to take it further by having an email sent out to a specific email account (Outlook 2010) confirming that a file has been uploaded or downloaded along with the file name.[code]...
Having no real experience with updater-style applications, basically I want a secondary EXE to be bundled with my application which will update the program file. Its a one file application - so its a simple process. Its just for the PC's inside the business.Currently, I think it will be easiest to get the updater to check a text file uploaded onto our server, and determine whether the running version number is above or below that. The new application will then be downloaded from a simple http link.
-I have an interface designed, so that will be attached to my request.
-Is it possible for the updater to update itself? How could I request that?
-Is there any way I can ask that the link which the updated file will be downloaded from is definitely hidden from the user?
-Will the developer incorporate error handling for if the program is running when the updater runs? How do I ask for that?
Is there a better way for the updating process to run? What other things should I ask the developer to include?

What I'm trying to do is get the bytes already uploaded. I cannot seem to do this.Another problem: When uploading, the form will not move or change Label1.text. When pbUpload.value == 100, THEN it changes to a different number than label3.text.
ok i know its not possible for a normal computer to exceed Long.MaxValue for Stopwatch.GetTimeStamp, but what is the scripted behavior of VB when Stopwatch.GetTimeStamp actually exceeds Long.MaxValue?
On Visual Studio 2008 I am running into problems with strings longer than 30 characters, which become blank. My context is slightly unusual (perhaps) - but I dont see why it should not work.I am calling a VB2008 script from C++ using the COM interface [URL].. It works fine with integer and real arguments, and with strings up to 30 characters long.(see below - the example above is easily generalized to arguments as String, in which case the C++ code declares a BSTR object and uses L"xxxx" to set the string to "xxxx").
Surprisingly, I get a problem if the C++ string exceeds 30 characters in length - the string received by the VB routine becomes "" , ie, completely blank.I checked and this is not just a limitation of the debugger viewer - it really is "". However there is no problem with local strings exceeding 30 chars - the problem appears in passing of the argument, both byVal and byRef.
I've drawing text to a rectangle, say for example "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789",That should be centered (which it is), but be on one line, not clipped like this:
"ABCDEFGHIJKLMNOPQR STUVWXYZ123456789"
my String Format is:
With sfFormat .Alignment = StringAlignment.Center .LineAlignment = StringAlignment.Center .Trimming = StringTrimming.Character .FormatFlags = StringFormatFlags.NoClip End With
It doesn't even have to trim it, like I have in my code, but it won't even stay on one line.
I had some trouble a while back with my progress bars exceeding their maximum sizes. I though I had fixed the problem but obviously I was wrong every time the maximum size is exeeded the application enteres debugging mode .... this is really frustrating as the progress bars are a major factor in the game...
What I have is one progress bar which is linked to a clock the clock which ticks up to 1:30 and the game then ends. I also have another progress bar showing the health of the shooter.
I have a series of collision codes set up which are linked to these progress bars, that add to them and take from them.
'Heath pick up collision code... If (HPU.Top + HPU.Height >= Shooter.Top) And (HPU.Top <= Shooter.Top + Shooter.Height) And (HPU.Left + HPU.Width >= Shooter.Left) And (HPU.Left <= Shooter.Left + Shooter.Width) And HPU.Visible = True Then
[Code]....
I have tried re-routing the overload so that if it cannot add no more to the progress bars it adds nothing to them.
here i am reading files from one root folder and after reading that we are moving that particular file Success folder and taking a copy of that in to back up folder normal
while reading file i will check file naming convention by targeting backup folder if suppose it was exists in backup folder then i m moving the file to duplicate folder
my problem if suppose again same file came to process this file already existed in duplicate folder how do send the file in to duplicate folder, unfornately i dint have any property as file rename
If File.Exists(Swift_Backup + "" + Path.GetFileName(CBFile)) Then ' File.Move(CBFile, Swift_Duplicate + "\" + Path.GetFileName(CBFile)) 'DUPLICATE FOLDER'
If you were to upload a project to any site but are concerned about the large file size, what are the only files you need to zip up for your project to work for either VB 2008 or VB 2010? So far I know you don't need the exe's, the pdbs, and xml files.
I've been reading gobs of articles on FTP upload in ASP.NET recently and they all seem to make sense, but every time I've tried implementing them I either get an empty file uploaded, or no file at all. Here are some of the articles I've been reading:Managing FTP Transfers from an ASP.NET Web Page By John Peterson FileUpload Control Doesn't Give Full Path...How to: Upload Files with the FileUpload Web Server Control I know exactly what the problem is but I don't know how to fix it. I can pass the file name from the FileUpload control, but the path does not exist for security concerns. However, the StreamReader object requires the fully qualified path of the file to be uploaded, so how the heck do I get that? I'm at my wits end!Let's use the example by John Peterson that I linked above. Here's the code:
Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim myFtpWebRequest As FtpWebRequest Dim myFtpWebResponse As FtpWebResponse
i would like to create a fixed size frame for user photos uploaded. I've tought: i, can create a fixed sized image (200 width x 600 height for example), with my personal frame (top, left, bottom, right element graphics) , and in the center a transparency.
Ok, but i don't know how to merge the photo into the frame and save the new photo format.
I'm using the code below to send large strings (500kB) to a server. I'd like to show the upload speed and in order to do that, I need to calculate the amount uploaded every second.
In a Timer that fires every second I get the BytesUploaded, divide it by 1024 in order to get KiloBytes (kB/s) and show it to the user. Then I set BytesUploaded to 0 and one second later do the same process.
The uploading is done asynchronously and the size of the data is added to BytesUploaded at once. This means that BytesUploaded is not being updated in a constant flow and has a totally different value almost every second.
I have a web application using VB ASP.NET 3.5 that along with many things allows users to upload documents into a directory on the web server. I would like to know how I can zip a folder on a webserver and download it to the client machine via a submit button.Currently, I have the files displayed as URLs so that the users can right-click and "Save Target As." But I think just having everything zipped in one file would make it alot easier for the users.
Normally when user upload a picture, how do u control the size of the picture uploaded by the user?
is there a way to change the size picture (scale the image according my size 300 x 150). Let say an user upload an image with (500 x 300), using picturebox, can i scale the image (500 x 300) to my picturebox size so that it can looks perfectly nice?
So, in this program I added 2 necessary login codes let's say, first a code that I will provide and then the username and password from my website. I implemented both ways, the first one worked perfectly, however, the second one is giving me some problems, my idea for that control was not using a database of users, that was going to be too complicated for a 14 year old guy, so I decided to take the source code for my website and I took a fragment, the boxes for the login, username, password, forgot your password, remember me and some other boxes, great, that worked perfectly, I uploaded the HTML modified document to my website's files and linked it to the URL of the webbrowser control in one new form, good, it's working, but I wanted a simple condition that works for this function "When the webbrowser loads the success website, hide me and show the past login form, when this one shows the failed login, popup a messagebox that says the error.". I have been looking for that simple condition for a long time. I am using Visual Basic 2010 Express Edition.
I want to use the GetFileInformationByHandle function under kernel32.dll in order to get the NTFS unique file identifier.The function declaration is like this [code]...
