I 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 1 RepliesI'm have a quite big application which have 2 serial ports and access 1 DB (running on Background workers). I'm experiencing some random locks while the application is running and I started looking for something that could cause it. One of the obvious possibilities would be if I had in the GUI thread some While_End that would never return.I have one While_End in my GUI thread but IMHO it does not look like it would lock, so I want your opinion: Does the code below looks like will lock?? If 'yes', Why ?

Does anyone can imagine a scenario where this While_End would not return ?
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 2 RepliesWe are developing an application in VB.NET that will need to accomodate remote users logging onto a Microsoft Terminal Server using RDP through the MSTSC.exe client.
Is it possible to offer an 'Upload' button which will allow the remote user to pick a file from his/her local hard drive and upload to the server ?
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.
Is there a way to determine if the application is running from an RDP session or not? Our staff has VPN access and use Microsoft's RDP Client to connect to their computers at the office. They mostly interract with software we've written. I'd like to identify those people that use our applications via RDP as opposed to being physically at their computer.
View 1 RepliesI'm looking for an API/function I can call to determine if software is running on Citrix, Terminal Services, or a stand-alone PC. Optimally, it would work something like this: [code]I would prefer something that worked from an API call as opposed to looking at something in the registry as we're having more and more customers that are locking down the registry.
View 3 RepliesWe want to set up a bunch of thin clients linked to a server running server 2003 using terminal services. When the thin client runs our app it needs to know which station it is so it can gather information unique to itself from the database. (IP address?). Our app is written in VB6.

View 3 RepliesI've developed a VB.NET application with Visual Studio 2008. The application communicates with SQL Server and processes a text file.
My question is about performance. While I run it from Visual Studio 2008, it takes 3 sec to complete. The same is when I run the executable created by the Setup Wizard on my desktop (Windows XP sp 3). But if I run the executable installed on a Windows 2003 Server, it takes 15 sec to complete! What could be the reason of degrading performance on the server vs. the desktop? The .Net framework 3.5 SP1 is installed both on the desktop and the server.
I'm developing a Windows application that runs on a terminal server and users connect to it via remote desktop. Standard stuff. However, I would like to know something about the user and I was wondering if there's a way to get some information about the client that the user connects from (his local machine).

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.

View 1 RepliesI develop windows applications in VB.NET using Visual Studio 2008. Recently I reloaded my pc and moved from XP to Windows 7 64 bit. Now when I am debugging, when I should get a runtime error, the executable instead locks up when it should bring up the code with the line that it crashed on like you'd expect in debug.
This doesn't happen all the time, only when I get a runtime error in a separate assembly that is not in the assembly I'm debugging. It used to work fine, but now it locks up. If I run the executable outside of Visual Studio (without debug) I at least get a runtime error like you'd hope for. I don't even get that when debugging.
I have a quite simple application that is having some random locks up. It's just a few text fields that the user fill it up, 3 sets of Radio buttons, one of them with flags to chose the language and click the PDF button. The application uses iTextsharp to load a PDf template, insert the text into it, depending on the language loads some extra text from a .xml file, and depending on the radio button removes the images from the PDF, closes the pdfstamper and uses [Code] to open the file with whatever PDF application the user have installed and closes itself.
Sounds simple, but after the application is installed in the machine (never in debugging mode) it randomly locks up the application. I tried re-publish the application commenting out the Start(filename) line and the thing stopped locking. And I double checked it, re-publish with the line again and it locked after just a few attempts. [Code]
I have a do until loop. But whenever my program get's to it, it always locks the application so I can't click on anything until the loop is finished. How do I fix this? I want to be able to stop the loop with a stop button.

View 1 RepliesWe want to store session in SQL Server. We have sessionState mode="SQLServer". I have been given a sample connectionstring as listed below. In this it is having both stateConnectionString and sqlConnectionString. Why do we need stateConnectionString when mode="SQLServer"?

stateConnectionString="tcpip=XXX.XX.XXX.XXX:42424"
sqlConnectionString="data source=XXX-FFFF-sql2k8,2025;

Note 1: SQLServer mode stores session state in a SQL Server database. Using this mode ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm. To use SQLServer mode, you must first be sure the ASP.NET session state database is installed on SQL Server. You can install the ASP.NET session state database using the Aspnet_regsql.exe tool
Note 2: StateServer mode stores session state in a process, referred to as the ASP.NET state service, that is separate from the ASP.NET worker process or IIS application pool. To use StateServer mode, you must first be sure the ASP.NET state service is running on the server used for the session store. To use StateServer mode in a Web farm, you must have the same encryption keys specified in the machineKey element of your Web configuration for all applications that are part of the Web farm.
I'm experiencing performance issues on my asp.net application. Sometimes it would take the client 30-40 seconds to execute a command, where as in sometimes it would take 3-4 seconds. I tried SQL Profiler and I don't see any problems. I was not able to replicate the issue on my side, under the same scenario when the client was trying.
I'm thinking that it might to do with session variables i'm using. I am using a lot of them to pass information within the page. However I Do not clear them.
I 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 used this way to make my shopping cart system :
Click here to see the example
when I add a product to the shopping cart it adds it very well but the problem is in the session, it stores it in the server not in the client browser.
so if some body visit the website from another computer he can see the added products on his browser while it should be empty.
Is there a way to save it on the client side instead of the server side ??
I'm using VB 2010, and am trying to add a simple TTS function to my program. I'm able to create a voice object, and get it to speak (Voice.Speak("whatever") with no difficulty.
The problem I'm having is that while the "whatever" is actually being spoken, the program doesn't seem to respond to input. The input does show up once the audio is through, but I really need to be able to detect some input (say, a mouse or button click) during a message and respond immediately, perhaps even stopping the audio.
Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.
