An application loaded on a citrix server executes with no problem. When we try to run the same program files on a virtual server, we get silent errors and we do not even see the application window appear. The program runs for a moment in task manager, but then closes down. BTW other .net apps run on the virtual server. Here is the error we see in the event viewer application logs[code]...

View 1 RepliesI have a Windows Forms application created in VS2005 which runs fine on the user desktop but when running in Terminal Server session it frequently locks up when the remote desktop window is minimised and the user is working locally.There is plenty of RAM on the server so this is not an issue, the only solution so far has been to force the user session to log off on the Terminal Server and then reconnect.

View 3 RepliesThe vb.net code:Dim fs2 As Object fs2 = CreateObject("Scripting.FileSystemObject")
gets an error when I try to make an executable file out of this program and run it via citrix server.
The error is, the executable file won't run at all. When I try to run this locally, there are no errors at all.
is there a way for a program to get a list of users that are logged into the terminal server that it is running on???

I have built an application in VB 2010 on my Windows 7 Pro desktop. I have a particular combo box with a datasource that is dynamically populated, depending on certain values entered by the user; it may or may not have any records in the datasource. When I run/install the application on my desktop, the combo box acts normal, if I click the dropdown button and the datasource contains no records, the combobox will show a single blank beneath the combobox (to indicate no records). When I perform the same action on server 2003, the combobox DOES NOT show a blank row, it does nothing! It act's like it's broken.

I have an application that will run on a terminal similar to a micros terminal. The terminal is already running another vendors app that captures the users logon ID from a swipecard. I need to capture the same logon ID at the same time. This is no problem, I just hook it.
The problem is I have another app which also captures swipes. In development I am running both apps for testing. It appears that when I unhook one app it unhooks both. Rehook and all is fine. As my two apps will never be on the same terminal this is not a problem. What I am concerned about is the vendors app unhooking mine or the other way around.
I would of thought that each app would have it's own ID and that each hook would be independent. I have considered finding a way to determine if a global hook is present and then use some logic to decide on unhooking or not but can't find anything.

I created a program in MS Visual Web Developer 2010. It has a form that simply launches a script that manipulates a database. The project lives in several files and they are all inherited so they see each other and it accesses a MSSQL Express DB on one of our servers.

I have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?

View 9 RepliesHaving recently installed IIS Express I was hoping that it was going to make life easier for me, but I've run into a problem almost straight away.Consider the following which is representative of some live code:
Public Shared Function GetServiceId() As String
Dim principal As MyCustomAuthentication.Principal.MyPrincipal
principal = CType(Thread.CurrentPrincipal, MyCustomAuthentication.Principal.MyPrincipal)
[code]....
Running the code under the ASP.NET Web Server (Cassini) everything is fine and I can see that Thread.CurrentPrincipal is of type MyCustomAuthentication.Principal.MyPrincipal.Running under IIS Express this same line throws an InvalidCastException and checking the type I find it is now of System.Security.Principal.GenericPrincipal which is confusing as nothing else has changed.I can confirm that MyCustomAuthentication.Principal.MyPrincipal implements IPrincipal and remember this is Live code, it is currently deployed and working.

View 2 RepliesI am in the process of converting vb6 assemblies to VB.NET.I am trying to overcome a particular design challenge.I have a vb6 EXE sitting on a Terminal Server which is shared between multiple customers.Each customer has customizations in the form of overrides to this EXE in custom business logic contained within DLL's.We know what DLL to look at based on a setting in the database.We use the CreateObject ("CustomerDLLName.CustomerClass") method to create late bound objects.If the object is "not nothing", we check for override code.For example, if my base EXE has a sub called PrintForm, based on the logged in user I may use the base sub within the executable, or I may need to use the sub in a custom DLL:
Dim oCustom as Object<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
Dim strSetting as String<o:p></o:p>
strSetting = "Customer1DLL.Class1"[code].....
I am struggling to come up with a comparable if not better way to do the same thing in .NET. I want to continue sharing the base EXE so I can't just have separate EXE's and DLL's in separate folders.They all need to live in the same c:/Program Files/[Application Name] root directory so I can take advantage of the Terminal Server's shared application memory.
Can anyone provide a script to close all open sessions in a Terminal Server?

I've basically made a basic tcp server/client application. The thing is that I'm behind a router and so will be the other people that use my clients. I've had to use port-forwarding or the software "rinetd"to run quite a few applications online.
Let me explain: I'm on a lan network that connects to the internet. Whenever I want to host a server - for instance a basic ftp or http server. If I give my external IP to anyone, they won't be able to access my server. Even if I portforward, it doesnt work. I have to use rinetd here. For other applications, portforwarding works. I'm not sure how these things work at all.
Anyway, my issue now is that I have created this server/client application. I'm having serious doubts that if I run the server, I'll have to either a) portforward or use rinetd to get people to connect to my server. IF I need to portforward, that's fine. However, using rinetd would really suck... My 2nd concern is as follows: IF the person running the client is in a similar situation as me (i.e he's on a lan that has a router which connects to the net), will he have to portforward or use rinetd as well? If he portforwards that's fine. But I don't think I could get people to use rinetd.... Also, if there are more than 1 person on a lan trying to connect to my server, there is a big problem when they try to portforward: they will only be able to allocate one of their internal ip to that port, and the others won't be able to connect, right? How does this work? I mean, I use many softwares like msn/skype/(some games)/firefox that do not need portforwarding/rinetd. Yet they work. My housemates(other people on the lan) use the same softwares, and it works fine. There's no clash/probs watsoever How come these run fine?
Anyway, back to my issues. Given I have no knowledge about how the above work, I was wondering whether there was a way to host a vb .net server application on an external website (external to my house) so that I might *avoid* the above mentioned problems, and to what extent that would be a sound solution.
Im planning to create a Remote Desktop Application and I'm having problem with viewing other computers monitor or screen.
