I'm having trouble getting a form working with MVC2. As soon as I change the form element to use 'enctype="multipart/form-data"' I get errors when submitting it. The code I've got creating the form is as follows:

With several form text field and a file upload being the only fields. Nothing too complicated!The action method that handles the form submission is as follows:

It's nothing too complicated either. The code that I've commented out would have inserted the image into the database, but I commented it out to see if it was causing the problem, but it's not.The error I'm getting is as follows:
Server Error in '/' Application.
Invalid character in a Base-64 string.

Obviously something is going terribly wrong here, but I'm at a complete loss as to what it is. The form works fine if I get rid of the multipart bit in the form element, but then of course it doesn't upload the image. I also get the error regardless of whether I've actually selected an image to upload, so it's not the actual image causing the error.
When i try to encrypt it goes fine.. but when i right after try to decrypt it i get an:"Length of the data to decrypt is invalid" error... the error occours when i try to run the code FlushFinalBlock();here is my code:

I know I can use arrayName.length to find out how many items in total in the array there are, but how can I gracefully find out how many items are in a specific dimension? I know I could probably do it in a for each loop, but it would look a little messy, does anyone know of a simple way that I may have overlooked?

View 2 RepliesI am new in asp .net.I am not able to undestand why we call base class method when we
override methods/events.Like automatically visual studio will put base.OnInit() if you are overriding OnInit.
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
same is the case of Finalize. In derived we call base.Finalize() Is there any need of calling these base class methods ?
I have to implement User base security in my Web project using .Net3.5. Followings are some we need:
Roles can be Admin, Manage, Editor, Member etc User can have multiple roles Every roles has its own dynamic menus and restrictions/resources All menus and interface will populate dynamically from Database
I heard some where this kind of i.e user base security can be implemented using HashTable but I dont know how is it?
Today I came to know that for this kind of work Java people use Interceptor Design patterns. So, how could I do the same in asp.net C#?
I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

Is there a way to set the horizontal-align in the code too I tried adding this
.PagerStyle.HorizontalAlign = Right

I recently started learning about HttpModules and made my first one. I was wondering if someone could explain why some modules in the the web.config include a lot of extra info and others do not.
example: not much info
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
example a lot of info
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
What is a publickeytoken, version, culture. Do I need to do anything special to use those?
I have to send a file to my webservice, but the webservice assumes the file (byte Array) as a base64Binary.
Before the encoding, the byteArrayFile is saved on disk as a regular File. (I'm doing it just for testing)
So, in my Java client for webservice, I'm sending the information this way:
String file = new sun.misc.BASE64Encoder().encode(byteArrayFile);
port.sendFileToWebService(file);
The webservice have to decode the information and save the received file on disk.

I have an AJAX service where I'm pulling HTML content. I want to Response.Write() it to the browser as a string. I can't figure out how to do it so it remains a string like this rather than formatting the HTML:
<div id="global_nav">
<ul>
<li class="left"><a class="sub practice" href="/practice-time"><span>Practice Time</span>.
I've tried using HTTPUtility.HTMLDecode(string), but that doesn't appear to do anything.
In my application, i want to do URL encoding And Decoding in my webservice. how i will do encoding and decoding.
View 4 RepliesI have this string test = HttpUtility.HtmlDecode("http://test.com/Folder1/Folder2/my%20view.aspx");When I look into test it still has %20 instead of a space. Why is it not decoding this?

I have vendors who are passing customers to us via an encoded URL. The problem is that Request.QueryString["FieldName"] is returning NULL on some of them and I can't fiqure out why?
For Example, one vendor is sending : http://.....ViewListing.aspx%3FListingID%3D1187721%26Source%3D6"] which returns a NULL value when Request.QueryString["ListingID"] is used.
Using Server.UrlDecode(Request.RawUrl.ToString()), however, will decode itpProperly as /ViewListing.aspx?ListingID=1187721&Source=6
How do I get the Request object to properly retrieve the values?
I would like to make sure that everything that goes into my database is safe, i.e. protection from sql injection.
What I want to do is type something in a textbox, "<b>hello</b>" for example, it be encoded before it's put in the database, but when I retrieve it, I want it to display "hello" in bold.
I've tried the obvious of server.encode on input and server.decode on the output (to a label and a literal control), but couldn't get it to display the text in bold without having unencoded text in the database.
