I use asp.net + MVC1.0 and in a webpage I have several forms, within each forms I have called the following function
AntiForgeryToken() to generate a hidden value, and in Controller function I have a validate attribute.

<html>

from time to another i find the following exception:
Invalid length for a Base-64 char array I use encryption and decryption: public static string Encrypt(string text)
[Code]....

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:
[Code]....
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:
[Code]....
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.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927
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.

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 1 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.

View 4 RepliesI have a list XML elements that I need to compare to chars in an array. Some of the XML elements start with uppercase characters and some dont.
So I need to convert the XML elements to lowercase to compare them against "alphabet".
I'm doing this by converting the XML element to a string. Then setting that to lowercase. Then converting that to a char. Then comparing that to each char in "alphabet".
Is there a better way to get the XML into lowercase? IE without the two conversions

how to change
XXX@YYY.ZZZ into XXX_YYY_ZZZ
One way i know is to use the string.replace(char, char) method,
but i want to replace "@" & "." The above method replaces just one char.
one more case is what if i have XX.X@YYY.ZZZ...
i still want the output to look like XX.X_YYY_ZZZ
is any meaning of # char in page url... u can see this in below [URL] see in last #tile=outlook...
View 12 RepliesI am using SQL Server 2008 Web Edition and it seems my SQL queries are automagically having the double quotes replaced with ' + CHAR(34) + '. I am trying to pin down why this is happening, I am using Delphi with ASP.NET and using the ADO.NET object for the SQL.
Has anyone come across this before?
When I try to run the following code it always spits out the hex representation, not the integer representation. Most of the examples I found on MSDN said this should work. What am I missing?
var stringBuilder = new StringBuilder("8");
int j = 0;
foreach (char item in stringBuilder.ToString())
{
j = Convert.ToInt32(item); //returns 38, need return to be 56
}
edit I should have made clear that I know the difference it's returning the hex value. I'm outputting the value to a file, and in that file, it still shows the hex value, not the integer, so I don't think it has anything to do with the debugging environment. edit2 Looks like a PEBKAC problem. Looked at the code that was writing to the file, and it was using a .toString("X") method, changing it to a Hex value. The fact that it was hex in my debug environment was what confused me.
i wanna convert char to double type and convert it to date.char->double then double -> date type.I have a whole string and i trim it into 3 parts. In my item(2) is a UNIX Timestamp i'm trying to convert it into date type.
