Hi all,

I have my previous application is running on .NET 1.1 (OS - MS SERVER 2003) and I have developed new application on .NET 2.0, so if I install .net freamework 2.0 on server will it create any problem for previous running application?

Because that use .NET 1.1 and I can select .NET 2.0 in ASP.NET in properties of my Virtual Directory website, so will it create any problem for previous running website?

I am new for doing all setup, please any help?

Thanks in advanced.

Snehal.

Yes, your server can only run one version of the .NET framework, AFAIK.

So it will create any problem for previous running website which is developed using .NET 1.1 if I install .NET 2.0 for new website?

Thanks a lot

Hi,
I have installed .NET 2.0 and from ASP.NET tab under IIS Virtual directory I have changed to .NET 2.0 but when I run that website it give still same error, and at bottom I look because it use .NET 1.1, do I need to register manually IIS with .NET?

When It was installing .NET framework I saw the instruction that it is registering IIS, please any help regarding this?

Thanks,

Snehal.

If it's an ASP.NET 2.0 site, and you set it to run with .NET 2.0, then that should be all you need. You can try asp_regiis.exe, if that doesn't work, nothing will.

What is the error ?

Thanks for your reply,

that's correct, I can register iis using asp_regiis.exe and than my site which I developed new will run properly but I am more worried about an existing site which is deployed by some other vendor and it is in .NET 1.1, so it might stop working when I upgrade to .NET 2.0, so do you recommend it will also work in .NET 2.0 without changing any .config in old website?

by the way error is "Unrecognized configuration section 'connectionStrings'" because it still use .NET 1.1 (as I haven't register IIS so) but after register IIS with .NET 2.0 what about existing site?

I'm not sure how often I can repeat this. Your IIS can only be registed with one version of IIS. Typically, a dev machine would have links to regiis, for each, so the user can switch between them easily. If you're deploying, you need a server for each.

AFAIK, you can run 2 ASP.Net Applications under different versions of .Net on the same IIS though I may be wrong.

Rijndael problems

Hello, I'm trying to send an encrypted picture with C#.
First I read the picture with a FileStream and get its bytes with this code:

public static byte[] Serializa(string Name)
{
FileInfo FichInfo = new FileInfo(Name);
if (!FichInfo.Exists)
return null;

MyFile = new FileStream(Name, System.IO.FileMode.Open);

BytesContent = new byte[MyFile.Length];

MyFile.Read(BytesContent, 0, (int)Fichero.Length);

MyFile.Flush();
MyFile.Close();
FichInfo = null;
return BytesContent;

}

Then I try to encrypt with Managed Rijndael and it throws an exception with the message "Length of the data to decrypt is invalid".
My code to encrypt is as follows:

public byte[] cifrar(byte[] obj)
{
return cifrador.TransformFinalBlock(obj, 0, obj.GetLength(0));

}

Thank you

It sounds like you have created a decryptor instead of an encryptor.

No, I have created both of them because my program needs to encrypt and decrypt data. I use the decryptor to decrypt data and the encryptor to encrypt data.
My program seems to deal ok with strings (I can encrypt and decrypt strings correctly) but the problem comes when I try to encrypt the picture.

The error message that you quoted refers to decrypting. Are you really sure that you get it when you are encrypting?

Have you checked the length of the array, so that you are not trying to encrypt an empty array?

You must be more specific.

Generally You acquire your data, insert them in the listbox aw though it was a simple one. Based on acquired data you check or uncheck certain items and then through CheckedItems property you continue on your next step that i didnot understand,.

Hi! Thanks for replying, I've switched to a listbox instead. I want to add items into the listbox. The items added are coming from my database.mdb I've set the listbox properties Datasource to database.mdb(which is my database name). For the case of the display member I set it to the column that I want to display. For the selection mode it will be multi-simple. I'm actually doing a selection of multiple student IDs to be reflected back into the database when a user selects the IDs that he/she wants. Is my way of doing it right?
