Hi!
I`m tryng to connect to a ftp-server which allows only a secure connection. Connecting with Flashfpx it works with both "auth ssl" and "auth tls", but when i try to do it with the menatils security-library and the example ftp-client i get this exception:
220 (glFTPd 2.00 Linux+TLS) ready.
AUTH TLS
234 AUTH TLS successful
Org.Mentalis.Security.SecurityException: An error occurs while communicating with the remote host. ---> Org.Mentalis.Security.Ssl.Shared.SslException: The server hello message uses a protocol that was not recognized.

I´ve read somewhere that the menatlis-library didn´t support dhe/dss and the server seems to need this. Here´s a part of the log when connecting with FlashFXP:
[R] AUTH SSL
[R] 234 AUTH SSL successful
[R] Connected. Negotiating SSL session..
[R] SSL negotiation successful...
[R] SSL encrypted session using cipher DHE-DSS-AES256-SHA (256 bits)
[R] PBSZ 0
[R] 200 PBSZ 0 successful
I´ve been told OpenSSL would support this authenticationmode, but i don´t have a clue how to use this library in my project. Any suggestions and help will be appreciated.

Dear all,
I developed a tool window, which is a custom graphical editor. Now I would
like to use standard visual studio undo/redo buttons and printing dialog.
But these buttons are disabled when my toolwindow is focused, and also not
passed to Querystatus of the addin. On other hand, for example, build-in
form editor can usees the buttons.
May be somebody could help me?
Thanks in advance,
Boni

This is probably a stupid basic question but...
When setting a new variable to the value of an existing reference variable how do you tell c# to copy the variable instead of copying the reference the variable holds.

Not exactly what you're after, but one solution is to implement ICloneable and call the Clone method.

Thanks for the suggestion.
What I eventually did was to create a Copy method and use the MemberwiseClone method to create a shallow copy of the object.

If you've ever used MFC before, you might remember the concept of separating document and view. Setting aside the debate about whether MFC is good or not, I'm developing an app right now that has a clear definition of a document that can be saved/loaded/printed and possibly edited in different views, and I think I could use some of the design that were quite rigidly enforced in MFC.
Unfortunately, I've lent my MFC book to a friend (probably about 5 years ago), and I can't remember some of the document/view separation ideas.
If anyone happens to remember the answers, here are my main questions:
-Should the main view create and manage the document object, or should it be created outside?
-Should the document object be able to access the view object (WinForms control), and should I use it from there? Should I worry about portability of the document object, or should I just worry about that when I serialize it and leave the view object out?
-Since objects within the document are in charge of drawing themselves, should the document object draw the whole view, or should that be up to the view object? If the latter, should I pass the Device Context (System.Drawing.Graphics in .NET) to each draw routine?
Thanks in advance.
By the way, don't you think it'd be cool if VS.NET had templates for SDI and MDI C# applications? Maybe we should post that on the Whidbey suggestions page.

Great, that's exactly what I was looking for.
I found this[^] article with a Google search for "view model controller pattern", and the last portion cleared up all my questions.
Thanks!

Hi,
i have a problem handeling powerpoint presentations with c# .net.
I have to copy all shapes and slides from an existing presentation to
another.
Only to copy the whole presentation doesn't work for me.
But when using .copy() and .paste() the formatting is lost.
Also the background and the slide master is not in the new
presentation.
Can anybody give me a little code how to handle this?
I've looked everywhere but found nothing about it.
Thanks a lot!

Hi all,
I have one question about the installer. I've set the RemovePreviousVersions of installer to true, and have changed the installer version every new release(it also changed the product code).
However, the installer still can't detect the pervious version of application. Do I miss any important steps?
Please hlep.
Regards

Hi
My installer is unable to remove assembly from Cache.i tried to run rd/s/q assemblyName command by starting Process but it`s giving access denied error,following is my code:
Assembly a = Assembly.LoadWithPartialName("MyAssembly");
curdir=Directory.GetCurrentDirectory();
getParent=Directory.GetParent(a.Location.ToString());
Console.WriteLine(getParent.ToString());
getParent=Directory.GetParent(getParent.ToString());
Console.WriteLine(getParent.ToString());
getParent=Directory.GetParent(getParent.ToString());
Console.WriteLine(getParent.ToString());
Directory.SetCurrentDirectory(getParent.ToString());
Console.WriteLine("Current Directory");
curdir=Directory.GetCurrentDirectory();
Console.WriteLine(curdir.ToString());
a=null;
System.Diagnostics.Process myproc=new Process();
myproc.StartInfo.RedirectStandardOutput=true;
myproc.StartInfo.UseShellExecute=false;
myproc.StartInfo.FileName="cmd.exe";
myproc.StartInfo.Arguments="/C rd/q/s MyAssembly";
myproc.StartInfo.WindowStyle=ProcessWindowStyle.Normal;
myproc.Start();
Console.WriteLine(myproc.StandardOutput.Read().ToString());
myproc.WaitForExit();
Console.WriteLine("Current Directory After Finishing of Process");
curdir=Directory.GetCurrentDirectory();
Console.WriteLine(curdir.ToString());
The executed command gives following O/P
MyAssembly\100~1.0__\MyAssembly.dll - Access is denied.
-1

intresting thing that when i run rd/s/q assemblyName on Command Prompt,it removes the file successfully
is there some .NET restriction to remove assemblies within framework?

Ok here's my take, from most used namespaces (packages in java?) to least used (but still used alot).
1. System - all things common to the framework, eg object, string, primitives.
2. System.Collections - few handy list classes.
The above is common to most, my personal preferences follows.
3. System.IO - all stream related classes, including the overlooked StringReader/Writer classes.
4. System.Reflection - allows you to get info at runtime for any class (including your own).
5. System.ComponentModel - type convertors.
6. System.Windows.Forms - all UI classes.
7. System.Xml - basic XML goodies.
8. System.Text - most notably StringBuilder class.
9. System.Net - basic network client classes.
10. System.Text.RegularExpressions - RegularExpressions.
11. System.Xml.Serialization - XML (de)serialization.
12. System.Runtime.InteropServices - support for calling lecagy dll's.
And finally you might wanna look at System.Data that has support classes for database interopablity, and the ASP.NET related namespaces (System.Web.*) for web stuff.

If you have Visual Studio, try typing "System." in a function. It'll bring up a list of all the namespaces and objects there, along with brief descriptions. SharpDevelop does the same thing, if you want a free IDE.

1) Keyboard language? You can't determine the web client keyboard from the server side. There is nothing that passes that information from client to server.
2) You can't! There is no way you can change a system-wide setting from inside the client web browser.
