I though vista came with .net framework 3.0 right? how come a vista user can't run an application i made with:
Imports System.Net
Imports System.IO
Imports Microsoft.Win32
these are all .net imports right? what's wrong?
i compile my form with the below code when i run it on vista work fine without any problem but when i try to run in on XP cant run... that happened with any XP machine.[code]when i run my exe to other Vista machines work fine... but on xp NO.
View 1 Repliesi made an application for serial communication. for this application i need to set delay time. during this delay time i m doing some other task. So for those task i need to take back control from delay function, for this purpose i am unsing Doevents() function.Its work fine On other OS (XP, Windows7 32/64-bit). But Application.DoEvents() function halt and crash in windows vista.
Private Sub TimeDelay(ByVal DT As Integer)
Dim StartTick As Integer
StartTick = Environment.TickCount()

How would I go about doing this? Like maybe if this folder exsists then user=vista else user=XP? How would I go about doing this?

View 3 RepliesWithin the application, I need to have two levels of access: Standard User and Power User,for example.These two levels can have the same access level within Windows.It is not my intention to elevate to administratoWhat is needed, is a way to have two different groups of users.ne group will be able to run the application while a second group has access to additional features within the application but not within the windows environment
It is my hope that there will be two user account types: 1) Standard User and 2) some other user type such as Power User or something else that will distinguish it from Standard User
My program runs under a limited account, and uses impersonation to access admin codeI also have a program in the same folder, that my program runs sometimes when it exitsBoth exe files are in the same folder in the "Program Files" folderIf I try to run the other file, I get a not found error.If I Raise the first program to admin (even though it should already have admin rights due to impersonate) it can run the second file.1. I don't want to raise to admin.2. I'm using the full path and file name to the file.3. That do i need so that dot net can find the file so that it runs.

View 4 RepliesI am trying to build a self-updating .NET application that will run in an environment with limited user accounts. No admin rights here. The application must run on Vista and XP, and probably Win 7 when it comes out.An X-copy deployment would be fine. I would prefer NOT to use click-once.So far I have tried a system where the application checks a manifest and downloads updated binaries, which worked great in development, but not so much when the app was installed.Vista refuses to to let me copy files to Program Files. After that, I tried downloading an updated .msi, which works except that the MSI has a UAC prompt -- no go if the user does not have an account with local admin privileges.
running the program in AppData and using the x-copy method might work, but I have not seen anyone say that they have tried it and it did work. Will that work for an account without admin rights? Can anyone vouch for this method before I start writing more code?

I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.

View 6 RepliesI am designing a fairly small application to manage a waiting area for a clinical department. There will be a receptionist who books appointments and updates exisiting appointments to say that a patient has "Arrived". In seperate rooms will be nurses who call patients who have "Arrived" and update the appointment as "In Session" and finally as "Discharged". The appointments are viewed in a flexgrid with nurses across the top and time down the left, patient names are displayed at the relevant times and the cells are shaded a colour to represent the current appointment status ("Booked", "Arrived", "In Session" and "Discharged").
I am using SQL Server as the back-end and Visual Basic 6 (I know) as my front-end.I have been told that there will be 2 or 3 nurses plus the receptionist logged in to the system but I would like to cater for growth.My question is what is the best mechanism to use in order to reflect the status change made by one user on the screens of the other users currently logged in?
I have been thinking about using a timer to refresh the data at a set interval but I do not want to keep hitting the server excessively (although what is considered excessive? we would be talking about a call for data every 60 secs per user). Plus the server could be serving data for many other applications so this is another consideration.Alternatively I have been thinking about sending some kind of message via Winsock to the other users notifying them of data changes as they happen. I don't have a lot of experience with this and am concerned about clients not receiving messages and users seeing old data. It also seems strange to me that once the days appointments have been retrieved from the database that "in theory" a client could go the whole day without having to query the database again to pick up changes - kind of scary.Some information on the data:We would probably be looking at around 100 appointments per day We capture patient name, date of birth, date and time of appointment and appointment status.What is the standard approach / best practice for this kind of scenario?

View 16 RepliesI'm running an application under an account that is not the account logged-on to the PC.
Within the application I need check if the logged-on user is a member of the Administrators group. Below is the code I'm using. From what I've read, WindowsIdentity.GetCurrent() should return an object associated with the logged-on user. It doesn't, it returns the same information as the call to System.Threading.Thread.CurrentPrincipal. Which is the information associated to the ID running the application, not the logged-on user.

View 8 RepliesI have a few programs published via ClickOnce. These are highly specialized programs, and are only used by a relative handful of people, but the set of users is likely to change, and is spread over a fairly wide geographical area. The major advantage of ClickOnce....ok, for me, the ONLY advantage of ClickOnce, is that I can create updates and have them (mostly) installed when the end user runs the program. Over the brief time that I have used it, I have encountered these aggravations regarding ClickOnce:
1) The application can only be installed on a user by user basis (it can't be installed for all users at once). I understand why this is done for a general solution like ClickOnce, but it is certainly an aggravation.
2) Updates don't always appear to happen. Usually, the updates do happen when a person starts the program, but a fair number of times, the update isn't noticed, or recognized, or something. This causes the user to continue with the old version, which makes them think that I didn't fix the bug they had, which causes them to give me a raft of excrement, which results in me flipping them the bird. Much hilarity ensues (fortunately, I'm friendly with my entire user group, so this is a fairly accurate acconting of the sequence of events, except that I just laugh at them rather than replying in sign language).
3) Certificates expire in a year. Certificates are a great thing...for some situations. In my case, an alternative seems like it might be better.
4) Some settings in the manifest are so doggone hard to fix that I've nearly given up. I changed the URL that ClickOnce was supposed to go to for updates, and found it impossible to change the program to find the new location. It had to be there somewhere, and I found several candidates, but never could find the critical one.
Because of these issues, I have been tempted to write my own replacement. There are a few issues that I'd like some commentary on. For one thing, security is an issue that is hard to pin down. None of the data I am dealing with is worth a second thought. No cracking of that data would harm anybody or any thing. However, my first thought would be to have people install an app that would go to a web service to check for the existence of an updated version. If one was available, then the existing program files would be overwritten by the new files. If one was not available, then no overwrites would take place. Lastly, if the service couldn't connect, then no overwrites would take place (of course). If the files were compressed for transport, it would be kind of difficult to intercept and inject a different program into the transport stream, so the only weakness that I can see would be if somebody hacked the server that held the new version, and replaced it with something else. What am I missing here?Also, has anybody done anything like this, and if so, what else am I overlooking?
In my application I have a several type of user could be log in. My purpose is to have a restriction with other menu to show on or off. In php I used a session to handle that user id. In vb.net how can assign user id and retrieve anytime I need it in every user that has been logged in, so that I can check the user type and do some action.
