I was just wondering if there is a way to have a program in visual basics 2010, some what selfdestruct. For example, when the user opens the program they have a time limit to use it and then it closes?

Currently following is the setup of my wifi connection.
Laptop 1 ------> Wifi Router <------
Laptop 2
There are about 5 laptops which connect to the wifi router to access internet. Network is password protected so anyone with a valid network key can connect and access internet.
I am planning to develop a local website which will be having a list of username and passwords. I will also remove the password of the wifi network so that anyone can connect.
If a connected system tries to access a web page in the internet then redirect them to a Login page (in the local website) and ask them to login. Once successfully logged i,n the mac id should be added to "Allow" list and monitoring starts. Internet should not be available for those who don't have a valid username and password.
I was thinking about developing the application to block/allow internet access though a vb.net/c# application.
I am okay with the website part. What I would like to know is
How I can block/allow internet access through the .net application. Is it possible in .net or should I be going for an unmanaged code development? If it is possible where is the best place to start? I have experience in winforms development but not much of network programming. Will there be any change in my current wifi setup? May be a new webserver/proxy server which will host the website and the windows application?
I want to create a limit to the amount of the space my application can take from the hard drive its running from.
View 5 RepliesI have designed and published my small created app with WINDOWS FORMS using VB 2010 EXP on Windows 7. I can only install the app on the machine that I used to develop the app.I want to install the app on another computer but I cannot. I usually have error reports.
Example:Unable to install or run this application. This application requires Microsoft Common Language Runtime 4.0.3 to be installed on your computer.
what can I do to be able to install the app on a different computer which does not have .Net and does not have visual basic 2010 installed.
my code caused "Application pool exceeded its job limit settings"when doing bulk update.My hosting provider told me that my code caused memory exceeded its limit.

I want to make my applications to have a self update function. My applications have only one file, the main .exe. For updating, I want to use the best way: the program download it's new version overwriting itself; and on next start the program will be the updated version. I tried to use the ShadowCopyFiles, but all the times the main file is locked, so cannot overwrite it (or delete or anything). I found many examples in the internet like this:

I've got quite a big application and I've just started noticing that not all runtime errors cause an error.
for example if I call a function that executes an SQL query and the query string uses invalid syntax or refers to a field that doesn't exist then that would normally cause an error at runtime. But it doesn't - as soon as it hits the error the function simply returns to the caller.
If I enclose the code in a try/catch then the error is trapped but, while developing, I just want a good old runtime error but not getting one.
The application run normally fine on several computer but today we got the error
View 6 RepliesI am making a video conversion tool. I have a listview with one item per file.And i also have options to add subtitles to movies. I want it to be like this:Say the user add 2 movies. He select the first movie in the listview and then go to the subtitle tab beside. There he checks a checkbox so he can add subtitles. Some controls comes up that allows he to browse for subtitle and select which language the subtitle is. Then when he has selected these options, he select the other movie, the program saves the subtitle data somewhere and then erases all fields so he can fill them with a subtitle for the other movie.
My.Settings is way to simple for this. But i don't want SQL or db related stuff.Is there a good storing way i have missed?
I 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.

We have a VB .Net application that is targeted to the .Net Framework version 2, over the past couple of days users have been reporting that they are getting the following error message when running the program?
View 8 RepliesI have developed an application using VB.NET (.NET 2.0). I have put an exe on 4 client machines, it works fine on 3 clients but fourth gives me the following error:

I have .NET 2.0 framework installed on the fourth machine.
sir, i have no idea how the code will look, but i want it to assign a value after reading from a text file and then store it for further use even if the text file is not there, but without using any external storage like registry, disk, ram. It should store the value in itself and do like this:-
dim variable1, variable2 as string
if file.exists("text.txt")

I have a WinForm program developed in VB.Net with Visual Studio 2005. The program needs Microsoft Office Runtime installed atleast on the computer to allow the application to run without any errors.
Is their a way to check the computer to see if the minimum of the Runtime or Microsoft Office is installed on the computer? If either isn't I would like to display a message to the user on the startup of the application that states to atleast go to Microsot's site (I have full link to Runtime Download) and download the runtime for free.
Or is their a way to include the runtime as a component with my install for the application so if it isn't installed on the computer already it will install when the application is installed?
I'm in a VB.NET application. I have referenced some java.* namespaces in my file and am utilizing objects and methods from this namespace throughout the code. Presumably this is relying upon J# to compile.
Imports java.util
Imports java.util.zip
Imports java.io
Are these JDK namespaces fully contained in the .NET framework, or will my clients need to have Java installed when they go to run my application?As a side note, I have not explicity referenced any external Java DLL's or anything. This is all pure .NET as far as my code is concerned.

View 3 RepliesYou can change the connection string at run-time like this. You make the connection string setting available for writing as a separate property inside the MySettings class:
Partial Friend NotInheritable Class MySettings
Public WriteOnly Property RunTimeConnectionString()
Set(ByVal value)
[code]....
Then, in some place when the application is being initialized (before using any table adapters of typed datasets), write something like:
My.Settings.RunTimeConnectionString = My.Settings.ProductionConnectionString
Where ProductionConnectionString is a simple String setting. It is a User Scope setting so every user can change it (by assigning a value to it, similar to the code above) and save it by calling My.Settings.Save()This code works well for connection strings which were initially created in the main project and stored in it's settings (= app.config file).
The connection string in the app.config actually has a longer name: MyApp.MySettings.MyConnectionString.When you have a connection string stored in the app.config in a class library project, and reference that project in the main project, the app.config files will somehow be merged, so the class library has it's settings.The thing that don't know how to do, is change a setting from the class library at run-time. I could copy the connection string setting from the class library to the main project's app.config. I must keep the same name, which looks something like: MyClassLibrary.My.MySettings.MyConnectionString.Can the same principle I showed above be somehow applied to this second connection string?
So I wrote a VB.net project in Visual studio.I have a scheduled task that is set to run the program every morning at 10AM. If I use windows explorer and double click the application, it runs fine.If I open task scheduler, open the task properties, and browse to the application, then choose run, the program fails, due to Runtime exceptions.I know I have the path entered correctly, since I can debug the instance when it crashes from the task scheduler. VS2010 pulls up my source code.The exception is System.IO.FileNotFoundException, remember, it works fine when I double click the app. If attach a debugger to the process after it is executed from the task scheduler, I can then restart the debugger, and Voila!, The application runs fine.
