View 4 RepliesWindows Forms VB Application.. I added a splashScreen to my application. And it was flashing only for a second then going away so I added a sleep timer to my Form Load event... The problem is now the splashScreen stays open even After Application exits, instead of simply closing at the end of the sleeptimer.. The Part of the Form Load event that is causing this is as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Threading.Thread.Sleep(5000)

I have just converting my VB6 project to VB.NET 2008. I have set up start with Model. It start with Main() sub, in Main sub I have declare as below:
Dim frm as new Formpwd
frm.show()
In formpwd I have UserId, PWD as test box and Two command buttons. The system executes form_load code and then PWD and UserId_Gotfoucus handler and then closes the system. Why is not waiting to accept UserId and PWD?
I had originally saved the project I was working on to my desktop, but now I have moved the folder to another location on my hard drive (didn't want it on my desktop anymore).
But since I've moved it I get the message:

Is there a simple way to update my project to the new folder location?

View 1 RepliesI copied a project I wrote on my XP machine to my other computer with Windows 7 64-bit. When I run it through VS2008 it exits immediately. It does not run a single line of code. The exit code is 0. I need to post what else it says. But I did find a posting about this saying the path to the temp files may be wrong for it but he did not know how to change this. If I create a new peoject and put a command button on it, the program runs. So I was wondering if it is something like the temp files or something else. The machine runs a compiled .exe of the program from the XP machone when installed on the Windows 7 machine. So I do not think it is the program not being compatible.

View 1 RepliesAny simple way of automatically updating a newer version of my application from a network share. Everything I have read pertains to an update from a web site. This is possibly a simple thing to do but as I have 6-8 users using the application I have to email them all stating there is a new version on the share and for them to copy and overwrite the existing application executable in the program filesapp directory. If this could be done on launching the program within the splash screen that would be fantastic.

View 2 RepliesI want to allow my user to add urls to a database, much as a user might add file names. I have a form with a label, a textbox, and a browse button. I would like the browse button to load the user's default browser and then have the final url appear in the textbox when the browser closes. I have not been able to do that, but I have come close. I have not found a way to capture the url from an arbitray browser, so I instead load ie.exe and then capture the url with an OnQuit handler. That works (even verified by the debugger) but I am unable to get the url to appear in the textbox without actually clicking in the textbox once ie closes. I would like a suggestion as to how to avoid making my user click in the textbox and, if possible, to load the user's default browser and still capture the url. Here is my code for the Browse button (IE is defined at the class level as Dim WithEvents IE As SHDocVw.InternetExplorer):
theURL = ""
IE = New SHDocVw.InternetExplorer
AddHandler IE.OnQuit, AddressOf HandleIEQuit

I 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 use VB 2005 Express @ home for developing stuff. I am wondering if anyone knows how to run a script automatically after building my application. When I click build I want it to compile my InnoSetup installer and also zip up my executable + readme.txt file into AppName-version.zip. Right now I manually do it, and it's not that big of a deal, but if I am just wondering if it's possible. I think I can do it with full VS, so I will check it at work, but I am wondering if I can write a plugin or something if VB2k5X doesn't have an option do it already built in.

View 5 RepliesI 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.

Im working on a silverlight application where a user can create, edit, delete objects. The changes they make are placed in a queue which is processed every 4 minutes. When it is processed, the updates are sent over an async web method call to be saved in a sql database, one at a time. When the first update finishes, the next starts.Im having a problem when a user makes a change and then exits the browser app before the 4 minute timer has expired.Currently the changes are getting lost.Ive built on what the guy working on this before me has done, and explored the Dispose and Finalize methods, trying to start the update process when the factory is being shut down, but that isnt working due to the async nature of the web service calls. I get errors saying needed objects have already been disposed of.
View 1 RepliesI'm running a bunch of automated tasks in a thread I'm creating via the Thread class. So I'm not using a BackgroundWorker.
During parts of the automation, the thread may exit. This is normal. But when the thread completes, I need to finish up some additional tasks. I can anticipate all of the conditions in which the thread closes, but I'd rather not to do the final tasks at each point, as this will create a lot of redundant code.
So instead, I wanted to write an event that is triggered when the thread exits. I looked through the Thread class, but all I could find was the ThreadState property, which has a Stopped property. But, when I try to add a handler to that property, it doesn't allow me.
For some reason, the next code found on MSDN crashes or exits after 30 cycles or, in other words, after processing 30th Property, exits without explanation. As I said, I found it in MSDN
