You can't. Sorry to keep shooting you down, but the only way to open word and excel files, is to use Word and Excel. Unless you wrote something on the server that controls Word and Excel, and then your own program that edited the data. You need Word to open Word files, and you need Excel to open Excel files.

I dont say that I dont use word and excel. But even though I need to display and edit the files by using a UI. Please try to understand my intensity of the problem. Thank you.

That's a massive undertaking. If you don't want to take me at my word, see the size of the source code for open office. You'd need to write something that big to make it work. If you need something more capable than the Office COM controls (mainly limited in terms of menu/toolbar options IIRC) your only practical option is an activeX container. Since porting/writing one (this is what the DSOframer is) appears to be beyond your abilities you'll have to look at finding and buying a commercial one from a component vendor.

Yes sir Dan,
I am ready to buy it. But the only condition is that control must be made by using managed code, the great architecture from Microsoft. Thats what I am always requesting to Christian. But he is feeling bad. I am sorry if I trouble you in any way.
As I am optimistic, I am trying it to find. Thats the problem is. Thank you.

Because it is 'the great architecture from Microsoft' :P
Seriously, this guy wants the functionality he's found in an ActiveX control, but his client doesn't want it to be ActiveX, because of security issues. He thought if he wrapped an ActiveX control in .NET, .NET would allow it to run without any security requirements. I am praying he is wrong....

Dear Christian, this is too much ya aqui. Yes, it is deffinitely more secured. You can ask to mMicrosoft also. It is secured because, .Net uses managed code, which will be rendered at client in the form of html which is secured and light weight. So please tell me, if you find any solution. Please. Thank you.

You are totally, totally lost. You're talking about ASP.NET. There is NO way that you can send just HTML to the client, and render/edit/save Word and Excel documents. Well, with a lot of javascript, perhaps, but if you do it, you should quit your job, and start a business selling the control you write.
indian143 wrote: .Net uses managed code
That has nothing to do with security. ASP.NET requires no permissions because, unlike ActiveX, it's not code on the client end, just HTML. Which is not enough to do what you want.

And I said 'I am praying he is wrong', not because I want you to fail ( I wouldn't be trying to help then ), but because if you're right, then we all have major security issues on our desktops.

So, is there no way except using activeX. Ok, then. Pray that may God help me. As I like to research the new things, I have been trying. If you get any idea, please send me to my email also.
Because, I keep those things with me, where I have been struck. But right now I am leaving this because I have to go with other things also. But I remember this as, I faced a real problem here in my development experience. And I am always thankful to you because you did more as a friend. Thank you.

You and your client seem to be under the misunderstanding that all things .NET are secure. Nothing could be further from the truth. I can get you to install an application on your machine that looks like it does it's job quite nicely, but in the background is actually going through your hard drive deleting files at random, under YOUR user ID.
You are also under the mistaken impression that a .NET Control does not need to be installed on the client-side in order for the client to use it. Again, nothing could be further from the truth. ESPECIALLY one that wraps an ActiveX control. Now, BOTH controls have to be installed on the client-side in order for it to work.

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.
The operative word being "Applcations"

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.
