Introduction 

Multi RDP Client .NET (formerly known as Multi Remote Desktop Client .NET) comes on handy when managing your RDP connections. A simple and friendly user interface for you to work and navigate easily through tabbed RDP remote window. Allows you to Import/Export .RDP files, Disconnect all connection at one click and Connect all your servers at one click as well. You can also change the resolution while working, set the window into fullscreen mode, and as well as enable window stretching and a lot more features!

Background 

Thanks to AxInterop.MSTSCLib (mstscax.dll) an ActiveX COM Component which you can use to connect on  Remote Desktop. So, I made a GUI for it for you to connect on your servers via terminal service on multiple window view in one application. How to use MSTSCAX.DLL? 

  1. You must have the ActiveX file in your system called "mstscax.dll".
  2. if not, then you can Google for the file and download it, then make sure you registered it using "RegSvr32 ". I think that's one of the IIS package if you installed the Remote Desktop Web Connection.
  3. On the UI Design mode in VS2005 or 8.

go to your toolbox and Open Choose Toolbox Items and look for Microsoft RDP Client Control in COM Components tab.

I'm guessing you successfully added that control in your toolbar. So I don't think I have to explain how to get that in your Form.

Introduction . Background . Screen Shots . Features . Codes . Release History 

Code Snippets  

A simple example code  on RDP connection to remote desktop. 

Well the basic code you need to know for you to connect on your server is this 

// for example, I have my AxMsRdpClient control named rdpClient.
rdpClient.Server = "sever name here"; 
rdpClient.UserName = "your username on remote pc"; 
rdpClient.AdvancedSettings2.ClearTextPassword = "you password on remote pc";
// optional 
rdpClient.ColorDepth = 16; // int value can be 8, 15, 16, or 24
rdpClient.DesktopWidth = 1024; // int value 
rdpClient.DesktopHeight = 768; // int value 
rdpClient.FullScreen = true|false; // boolean value that can be True or False
// and connect 
rdpClient.Connect();  

The code above is the simplest way of using the component 

Setting full screen in runtime is fairly simple 

// just set the Fullsceen property to TRUE
rdpClient.Fullscreen = true;
// strecth the screen
rdpClient.AdvanceSettings3.SmartSizing = true; 

Points of interest about connection and disconnection

I implemented a Reconnect feature. But its not easy as calling Disconnect() and Connect().

You should wait until it properly disconnected and call Connect()

In AxMsRdpClient, there is a Connect property which acts as a Connection Status: 

  • 1 = Connected 
  • 0 = Disconnected 

Now reconnecting can be done by doing this:

// call Disconnect() method on AxMsRdpClient
rdpClient.Disconnect();

// wait for the server to properly disconnect
while (rdpClient.Connected != 0)
{
    System.Threading.Thread.Sleep(1000);
    Application.DoEvents(); 
} 
// call Connect() method on AxMsRdpClient  

You can always implement your own way of reconnecting, the code above is just the very basic, I do not recommend you to use that. 

Here's my RDPFile Reader class

We also have DataProtection class which was provided by Microsoft and a little bit of modification and some methods to implement such as converting Byte[] < to > Hex blob. We could create a MSTSC valid password.

Remko Weijnen - "psw" descriptor on CryptProtectData

Now I have created a wrapper called DataProtectionForRDPWrapper to easily Encrypt and Decrypt RDP password CREATED in DataProtection class. Why did I emphasize the "created" word. Some limitation on DataProtection class is, we can't decrypt the password created by MSTSC and still under research.

UPDATE:

Full Release / April 2 
NEW: - From the requests of Simon Capewell and shmulyeng - Simon Capewell Requests: 
--- DONE(03222009_1254)1. Allow connection to servers on a specific port using AdvancedSettings2.RDPPort 
--- DONE(03192009_0916)2. More screen resolutions on the slider - most obviously 1152x864 and 1280x1024. 
--- DONE(03202009_1341)3. Context menu on the list of servers. 
--- DONE(03222009_1254)4. Options for different icon sizes for the list of servers. 
--- DONE(03227009_0138)5. Groupings for servers - handy if you have lots of clients 
    each of whom have multiple servers. You could launch sessions for all the items in the group. 
--- DONE(03212009_1321)6. Auto hide or view menu option to show/hide the sidebar (similar to Visual Studio). 
--- DONE(03192009_0200)7. Clicking Delete Server or Edit Settings when there are no servers throws an exception. 

--- Here's another one that's just occurred. I use Launchy to index a directory with a load of .rdp files in it, 
    which means I can just type Ctrl+space then a portion of the server name and launch it. To do that with this tool it'd need to: 
--- DONE(03272009_1129)1. Be able to launch a connection from the built in server list from the command line. 
--- DONE(03272009_1129)2. Have a command line switch to open the connection in an existing instance of the app. 
--- DONE(03272009_1129)3. Perhaps even be able to launch connections from the command line 
    using rdp files rather than the built in server list. 
- shmulyeng requests: 
--- DONE(03272009_0252)Ability to password protect the server list. 
--- DONE(03202009_1341)Ability to right click on a connection item in the list to edit connection details. 
--- (WILL TRY) Ability to log out of a connection rather than disconnect. 
--- DONE(03212009_1321)One thing I like about Palantir is the tabs of open connections. 
- and I added some 
- CAPTCHA verfication on startup password. 
--- When an incorrrect password is entered 3x, CAPTCH verification panel will show up.
- SQLite3
--- scrap XML!! :P

- LiveInformationBox 1.0 
--- Is a class library that pops up whenever you hover on a specified 
    control and shows some details about what the controls can do. 
--- The information shown on information box is an xml base. 
--- this is better than showing some information on a status strip :P 
- ListViewEx 
--- hooks some control (not just common control) to disable/enable if 
    listview has no item or when a selectio is made on listview items. 
--- good for automating controls instead of doing tons of lines just to disable/enable different controls.
