VS 2010 Application.restart() After Downloading A New Update
Sep 9, 2010
I was trying to use application.restart() to restart my application after downloading a new update. It seems to run into the problem where it is trying to start the new application before the original is closed so it errors out and never starts. After reading through some threads here I determined the better way to handle it would be
application.exit() process.start(application.executablepath) This didn't work and gave me what seems to be the same problem. I would also like to note this works fine when running the application through visual studios, it is only when I try to run this independent of VS2010 that the application never restarts.

I've deployed an application inside a corporate network and I want the update process to require less attention from users. Giving them a choice to update is not a porogative.I've written code to detect when new updates are available automatically rather than letting ClickOnce check on application start. I'm wondering if its necessary to restart the app after the update has completed. Currently I invoke at the end of my update script:Application.Restart()
But what if (to make the update process more transparent for the user), I performed a 'silent' update in the background on a separate thread, and then displayed an icon prompting the user to restart the app to apply the changes? Would it work this way?
Furthermore, if I ran my custom InstallUpdate() process on a timer, say every 2 hours, would ClickOnce be happy to continue to update for every new version that was released even thought the user has not restarted (and I'm expecting the updates only to apply once the user restarts the app)?

I'm using my.settings to store different communication parameters. After changing parameters, for several reasons, it's easier to restart the application then to re-initialize all objects/variables/etc using program code.
When I change my.settings and use save to save them. When I quit the application and manually start it again, the newly saved settings are used.
When I use either .restart, or application.exit in combination with process.start. The application will use the old values for my.settings.
If I read up on .restart there's a remark mentioning that it will restart the application using the initially used settings.
Before restarting the application, I manually checked if the new settings were really save to the user.config file, and they were.
My question: Is there a way to restart the application using either .restart, or application.exit in combination with process.start which will use the newly saved my.settings values?

I place some code below to simplify the process.
1) I am trying to use background worker to download a large file and update a progress bar to reflect the changes as the large 5GB file is being downloaded, and also update percentage completed to the label.text(lblInfo).
2) As I was goggling I came across some info that a web client is needed to calculate the maximum size of the file and divide by 100 and you can stream it down with the web client. Reading it is one thing, implementing it is another as I spent week trying to get it to work.

Is it possible to restart a VB.NET application, but with different command line arguments than it originally had? Here is the challenge. I want to write a single instance application. If the second instance has the same CL args as the first, then the built-in behavior is fine (second instance never opens, e.BringToForeground=True brings 1st instance to foreground, everything is great). But if the second instance has different CL args, then I would like the first instance to close and the second instance to start. However, once you mark a VB.NET app as "single instance only", it appears that you can never get the second instance. I think: OK, fine, I can just restart my first instance from the StartupNextInstance event. But how do I use the new command line arguments from the second instance? The Restart() method does not take CL args that I can see.

In my code the application will restart using the Application.Restart statement from another form named frmDatabase.
The application seems to restart while debugging but yet the dataset, tables etc which is declared right below the class declaration for the startup form seems to fail initializing when the restart is done.
Compiling and running the application works like a charm and there is no error like this when running the executeable.
I also Inserted a breakpoint in the Form_Load event and the debugger seems to skip all the statements when the application is restarted all the way down to where the exception occurs.
Declarations:
Public Class frmMain
Public objConnection As New OleDbConnection(strConnectionString)
Public objDataSet As New DataSet
Public objCommand As New OleDbCommand
Public objDataAdapter As New OleDbDataAdapter(objCommand)

I have an application with a splash screen which gets shown before the application starts. One of the requirements of the application is to allow users to restart (or atleast clear the form) so that other test cases can be ran. Because there are so many forms and variables, we elected to simply call Application.Restart() to accomplish this.
What we would like to do now is disable the Splash Screen when Application.Restart() is called. That is, only show the Splash Screen when the application is initially started, not when it is restarted.

I developed a chat application with an attendant chat server. Everything is working fine. The issue now is the fact that whenever the chat server goes down (for instance, the server system shuts down as a result of power failure or some other problem), by the time the server system come back on, the chat server would have to be restarted manually.
I believe (and I know) it is more appropriate for the chat server application to restart itself when the computer comes back on (and of course regardless of who is logged in and of course, even before anyone logs in). I have a batch file that executes the chat server. My attempt was to create a windows service that start automatically and runs this batch file using a Network Service account on the server system. Although, I'm having a hard time with this (temporarily), I would love to ask if there are any alternatives to using a windows service.

I have an application that opens up Excel, reads some information, then closes Excel. I developed this application using Microsoft Office XP 2007. A few weeks ago, my company upgraded to Microsoft Office 2010. The applications still works fine, but I can not compile in VS 2008 anymore. I get the error message: "Error 3 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'." I have updated my COM reference to Microsoft Office 14.0 Object Library, but the same message appears. [code]Obviously there is a bunch of stuff under this, but this shows where the errors are.I am unable to fix a bug in the program because I can not even compile it without error.

I have a program I would like to release, has 2 programs within it.1. The main program. 2. A resource utility.To release it, i'm going to package them both up using a 3rd party setup maker.Now, the question is this.I noticed in the snippets...theres 2 options.Update application synchronously or asynchronously.
First, whats the difference between the 2?Also, could I utilize that so it'll update from the clickonce, so I dont have to keep repackaging it?Also, I want all updates to be mandatory, vs optional like in clickonce default updates..where it gave the user the option to skip.Reasoning is, for cracks, hacks, etc, if it is modified, and i notice cracks, etc. it'll update and replace any cracks, etc. No "skip the update, so the hack/crack continues to work".

Basically I want to create a little program with 5 or so text fields where I enter the specific names of movies. Upon pressing a "go" button it then does a google search(with certain criteria) for all textfield entries on the website [URL} and then download the files, if possible without opening a browser.
Search criteria:
-only video formats(.avi .mov etc)
-download url contains the "_de" tag (to insure german trailers)
That way it should hopefully find the right trailer and download it. If possible have it use progress bars.
How much work do you think this is? Or is it even possible? From a logical standpoint I don't think it's too much work... I am using Microsoft Visual Studio 2008 Express Edition. My project currently is just full of test code but I will post it anyway:
Code:
Public Class Mainwindow
Private Sub Mainwindow_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

1. Just looking for some general help on how to auto update my application via a file location path (e.g. I have a HTML file containing the current file version and the .exe file to download)
What I need is to read in the HTML file version - DONE Check file version vs HTML file stream input - DONE Replace current .exe file with new .exe file - HAVING ISSUES WITH THIS
I know I have to close the application and then replace the old exe file with the new exe file then restart the application but looking for the best/safest way this can be done
2. Basically what I want is during my Splash screen which runs for 5 seconds I want to check if a network drive is mapped.
if not, pause splash screen ask user for address of drive, map drive then un-pause splash screen and continue with load how do I check if a network drive is mapped? and how do I pause the splash screen?

I was wondering if there was anyway to 'scan' page sources of websites and download only certain files based on their extensions, as you would by going to view -> page source in a web browser? Then, saving, perhaps, a .pdf, or a .swf file? I really don't know where to start.

I'd like to convert a VB6 application to .Net. It downloads multiple files at once and the progress is shown in a Listview. I'm using the Winsock control in a Usercontrol. Every time I start a new download a new instance of the Usercontrol is loaded. This way I can easily download 25 files at once with very low CPU usage.
I looked into the WebClient Class to download the files, but I noticed it only downloads two files at a time. Other downloads won't start unless one of the first two downloads are finished, but maybe I'm doing something wrong.
1) What's the best way to download dozens of files at once? It must be possible to resume the downloads.
2) How do I keep the downloads apart (index number?), so the Listview can be updated accordingly? I don't need help with the Listview itself.
3) Should I use the Backgroundworker or not?

What I am wanting to do is create a program that will load up a page (it is password protected) and get the links out of any files that I need to download. The green text is the text that contains the link and will be repeated for every file.One little thing is that there are multiple pages that are accessed through JavaScript with the code highlighted in red. So, I also need to step through the pages and get a list of all files on subsequent pages.
Everytime I run this program, it will get a list of all files and only download the ones that aren't already downloaded. However, I have never done this before and was wondering what I need.I have accessed the source of pages and parsed it for things like links before, but not sure if that is the optimal way or if there is some other way to handle this particular situation easier, especially since I have multiple pages to deal with and JavaScript.
