I'm working on a form where a user can submit a file through asp:fileupload, but want to display a specific error message if the user uploads a file exceeding 10MB. However, when I put a try catch statement, my error message does not get displayed, only the default one.How do I make sure it gets displayed?
Try
If fuAttach.HasFile Then
Dim filename As String = fuAttach.FileName

View 2 RepliesI'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

View 2 RepliesWhat is the maximum size of a multidimensional array in VB.NET (in my case two-dimensional)? I'm using Visual Studio 2008, Framework 3.5 I found in msdn [URL]: "The length of every dimension of an array is limited to the maximum value of a Long data type, which is (2 ^ 64) - 1. The total size limit of an array varies, based on your operating system and how much memory is available. Using an array that exceeds the amount of RAM available on your system is slower because the data must be read from and written to disk." However, I am trying to use an array of data type single, with dimensions 64513 by 301 but Visual Studio seems to freeze when I execute the line to redimension the array ( Redim myArray(64513, 301) ). I have 4Gb of RAM and am using Windows XP (32-bit).

I created a script for caching some images my program needs, so they aren't downloaded from the web everytime. But the cache folder is getting big, and it's getting big fast. It's not really the plan to have a cache of 1Gb or something like that, so I would like to create something like this to set the maximum size:
But I don't really know were to start. Sure I can create some check, and if the maximum is exceeded, remove the whole map, or the oldest files. But maybe the oldest files are the one's used the most.

View 5 RepliesIt is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

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 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

I need to create a FileUpload control from the code behind page. I have this function:[code]However, even though I successfully use a similar technique for other form controls, my FormUpload doesn't get rendered to the page.I'm writing the returned FileUpload to a DIV on the page outside of my function.Update: It's sorted. Seemed to be a problem with Visual Studio. Closing it, relaunching and then rebuilding the website sorted it.
View 1 RepliesThe fileupload control works well for files < 4MB (maxrequestlength), but if the file is larger than this the program fails with: - Server error in '/xxxxx' application Maximum request length exceededHow do I trap this so that I can return a better error message? The failure occurs before the Page Load from any callback, so I can't see any way of trapping the error, and I haven't seen any event or property of the Fileupload control that I can set to say "Do this when Max Request Length is exceeded"
