How do I check the connectivity to Remote Desktop through Visual Basic (if possible). I would like to run a program checking if servers is up running normally. In some cases servers will respond to ping, without being able to connect to RDP. It would be great to a program being able to detect loss of RDP-connectivity almost as soon as any problems appear.

View 8 RepliesI need my application to check for internet connectivity on my user's computer. If there is, an image is displayed and if there isn't, a different image is displayed. Here's the code I used to get this to work:
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
If NetworkInformation.NetworkInterface.GetIsNetworkAvailable Then
Dim bi1 As New BitmapImage

I decided to test this on my own computer by changing my default gateway (thereby making it seem as if I lost connection). But I realized that the code still showed that I was connected. So I'm thinking that it's only checking for connectivity of the interface - which in this case, is my connection to the router (which is true, I was connected to the router).How do I check that the user's PC is actually connected to the internet? I read the article Check for Internet connectivity but it's in C# and I don't understand that.

View 14 RepliesI am trying to verify connectivity from my application to various servers - For now I am only concerned with mail servers... (later SQL etc)Before anyone gets all upset and thinking this is for SPAM - wrong - these are to confirm connectivity from the application for sending logs OR to ensure the SQL conneciton is working appropriately - Those that want to SPAM can do this simply by getting LINUX and doing it for free with ANY mail client (I add this ONLY because MOST SMTP threads go unanswered... which is silly... there are MANY good reasons to work with mail within an application.....)So what I have tried is opening a telnet session, grabbing the output, and going from there...But it is not working.... the output contains nothing specific to the telnet session I initiate - and.... of course from the command prompt manually i DO get the proper responses

I get the command prompt header, I see the commands... I see the prompts... but after the telnet command there is nothing I am assuming there is an issue redirecting telnet info and the telnet session terminates the second I try to read the data

I have a problem with a large application that consists of windows forms mainly, but some WPF windows and controls (we also use DevExpress controls v9.1). The problem is that the application sometimes hangs when it runs in a remote desktop session, and that session gets locked due to inactivity, and the user comes back and unlocks the session. The hang seems very similar to the hangs you get when accessing GUI controls from a none GUI thread, but I'm pretty sure that's not what causes the problem. (We had a lot of those problems earlier, and have fixed all multithreading problems we were able to find. And the hangs now never occures when the application runs outside the remote desktop environment.)
I've done a lot of research on the problem but I've still not found a clear point to what causes the problem. However, I think there might be a problem related to some combination of remote desktop and .NET framework. The reason for this is posts like this:

I want to be able to view the desktop in almost-realtime from a computer on my lan (its part of my business) As this is a business situation teamviewer is not free, but id rather like to make my own server and client anyway - will be fun! I need to know the best way of sending the desktop fast to the second computer. I know of several ways to do this: take image of screen be it jpeg/bmp or whatever and send it as many times a second as i can (too slow) take an image of the screen and compare it with the previous image and send the bytes that have changed. take multiple images of the screen compare with previous images and send through the bytes that have changed.
View 1 RepliesIs there anyway, in a program, to detect if a program is being run from inside a remote desktop session or if the program is being run normal in .NET 2.0? What I'm trying to do is, I create a timeclock application which will clock a person in and out and keep track. But this particular person, I suspect, is remoting into their computer at work, from home, and clocking in and out.
View 5 RepliesI am trying to overcome a problem I am having with remote desktop.Basically I have 2 machines running in different locations. I use remote desktop to access one of them (the "Remote Machine") from the other.("My PC")The "Remote Machine" is performing automated tasks that require the screen to be active, not the user login screen.
When I do so the Remote Machine logs off and presents the normal windows login screen.When I am finished reviewing the remote machine I log off and then I need to log back into the "remote" machine. It has no monitior but I can log in by pressing the enter key which sends a keypress to log into the user account( there is only one). In fact I do this the other way around. I press the enter key on the "Remote Machine" and this logs the user back in - terminating the remote session on "MyPC".
The problem is I have to physically go to the Remote Machine to press this enter key.This is a hassle - One solution is to remotely re-boot the remote pc but the lead time involved is too great.I am unable to fix this problem by tweaking setting or registry hacks so I guess the solution must be to cause the remote user to log back in programatically.I am an experienced VB user but I have never worked outside the windows environment. Ideally I would like to programmtically send a keystroke "{enter}" to the login screen but this doesn't work.

View 9 RepliesI created an application that opens certain Microsoft Windows built in functions depending on what button you use. I have Text Fields setup for certain things like IP/URL, Username, Password, Port, Service. Depending on what function you want it pulls data from these fields.
When someone clicks on Remote Desktop I would like it to pull from the IP/URL, Username and Passwords fields. Right now it pulls only from the IP/URL field. How can I have it populate the Remote Desktop login, pulling the data from my Username and Password fields?
I have found a Login DLL that someone wrote and also found a Remote Desktop DLL but I do not know how to tie these into my program. I somewhat know the process of using a DLL in a VB project but I don't know how to tie these in.
FYI, I would like to be able to make my application a single executable instead of having multiple files that are installed by an Setup program.
Another feature of my program is being able to stop and start a service. I can use Taskkill and have it pull the username and password just because Taskkill has this built in with switches. This is ok for ending tasks but when I try to use SC to start the tasks, it only works locally because the remote server has a different username and password. SC does not have a switch for username and password.
Also another FYI, I do not want to use a 3rd party software that may not be on the remote computer/server. i.e. PSKill, PSExec, VNC or another program..... unless these can be imported into my single executable program and not have to be on the computer. As I mentioned, I do not like having to rely on 3rd party applications.
