Fileupload Control Is Not Working At Other Location & Give Exception "file Could Not Found"
Aug 11, 2010
fileupload control doesnt allow to select multiple files, then what i did , i select a file of directory and by coding i got its directory path. and showing all files of that directory in checklistbox control.So now user can select multiple files and can send selected file. I know its not a proper way, but i am getting a control that can allow me to select multiple files, If you let me know about the control that will allow me to do that , then this is what my onlyOk come to my problem with fileupload control, it works fine when run locally. but at other location its giving me a exception of path is invalid and file not found and one more thing its looking for this location "Could not findfile 'c:windowssystem32inetsrv"
Create a asp.net mvc project with the default template and used bmc appsight to monitor the w3wp process ; so when ever an action is clicked an exception is occured in iiscore.dll here is the sample one which i got.
I have a file upload control on my page. The maximum request length set is 8 MB (maxRequestLength = 8192). I also have server validation that throws an error if the file is more than 4MB. The reason that its 8MB in the config is the leverage that's given to the user and also that the app can be tested.
If I upload a file that's 9MB, I get thrown an exception "Maximum request length exceeded.", which is fine and as expected.
But when I try to upload a file that's 1GB, it shows me a HTTP 404 - File not found. how can I get it throw me a maxRequestLength exception?
I'm using a HttpHandler to intercept PDF file download requests and modify the PDF file. I'm stuck on what to do if the requested file doesn't exist on the webserver. If I handle the Exception and return an empty response, it gives the user a 0 byte file to download. If I ignore the Exception, then ASP.NET catches it and the user is redirected to my unfriendly customError page.
if i browse for a text file and displays it in the text box and trying to save it as the name provided above i am getting the error as Directory Not Found Exception.
I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
public void ZipExtract(string zipfilename, string outputDirectory) { using (ZipFile zip = ZipFile.Read(zipfilename))//file not found exception { Directory.CreateDirectory(outputDirectory); zip.ExtractSelectedEntries("name=*.jpg,*.jpeg,*.png,*.gif,*.bmp", " ", outputDirectory, ExtractExistingFileAction.OverwriteSilently); } } [code]...
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?
So I have a strange problem. I have 2 LinkButtons on a form with their OnCommand event attached. Everything works fine locally when debugging but when I publish the web site with I get the following error:
404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.
I also tried the OnClick event but I get the same results.
This is being published to IIS 7.
The OnCommand is just doing a redirect. I can manually do the redirect by entering the url the same way it's passed to redirect and it works fine. I also tried putting some code in just to verify that the event really gets called on the server and it seems it doesn't. Although it does work fine locally. I also tried removing all the files from the server and doing a clean publish just to make sure I wasn't missing anything.
fileupload control is inside a grid, When Ajax is not used its s working correctly, so as wen i use a Update panel, am getting a error in uploading my file to thr database.
I want to uplaod my images into the database.it works fine if my images are inserted into the database on postback,but when i put my FileUpload control in UpdatePanel the FileUpload.PostedFile property shows NULL.remember my scriptmanager tag is in master page.
I do not want to change the default settings for file upload, 4Mb is more than enough for the project I'm working on. After quite a bit of searching I found two approaches that were purported to work but neither one is preventing the "Maximum request length exceeded" error. The first approach[see ref. #1 below] performs validation with a custom validator and in code behind on the page that contains the FileUpload control. It doesn't work. The second approach [see ref #2 below] performs validation in the Application_BeginRequest event in Global.asax. The author stated that validation must be handled by this event. Quoting: "The way to get past is to use your Application_BeginRequest event to handle the problem.. This event takes place for each request to your application BEFORE the data has been completely uploaded. Here you can check for the content length of the request and then redirect to the some error page or the same page with some value in session or query string so that the page can show appropriate message to the user." Here is my code from Golbal.asax based on the above. As noted, this approach doesn't work either.
protected void Application_BeginRequest(object sender, EventArgs e) { const int maxFileSize = 4 * 1000000; // Slightly less than 4Mb if (Request.ContentLength > maxFileSize) { Response.Redirect("~/FileUploadError.aspx"); } }
One comment by a reader of the Global.asax approach was that the value returned by Request.Content.Length would include everything on the page, i.e. viewstate, image and text content, etc. I suppose one work-around would be to set the limit higher in web.config but validate for max. file size in code behind, but that seems kind of silly because I'm manipulating the uploaded files (images) to reduce the size anyway; storage space isn't the issue, performance is. Has anyone managed to solve this poblem?
I am planning to create a web page with the name of the student, course,pic and the resume to be uploaded by the user for specified students...
If I upload the resumes of students with same name how to differentiate. Looking for creating a name of the file name randomly as next I'm planning to retrieve the resume via search function to download and view the resumes....
Saving the resumes with same name with differentiate or randomly to save the files with new file name....
