I have recently implemented to following code on a good deal of my forms.
Public Overrides Function InitializeLifetimeService() As Object
Return Nothing
End Function
It has worked great to solve some of my odd application hangs when the application has been running > 1 week.However, when the user closes the program I now get an Application Crash screen.how to stop this? how to put it back to "normal" with a global variable?
Public Overrides Function InitializeLifetimeService() As Object
if readytoExit then
' Return... not nothing?[code]......
I have a backup program that is currently running in our Corporate Environment on about 70 machines. A mixture of Laptops, Desktops and Windows (xp-32, vista-32, vista-64, 7-32-7-64) with no problems.
There is one exception, and it's the reason I'm posting here for assistance.On one machine that is a Dell Latitude running Windows 7 64 bit with .Net 4 Framework installed the console application will crash immediately before it starts Sub Main. It simply give the generic windows error "A problem caused the program to stop working correctly." with no option to see debug info.

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.
I made a application in VB.Net. But some users face crash upon startup. That is "A problem caused this program from working correctly" with just one button "Close the program". Since there are lot of things happening when the app loads
View 1 RepliesI created a windows application service that runs every 20 seconds to collect data from avaya cms and then dump it into a database. I did this using a timer. Since I had to have access to the clipboard to get the data and parse it, I had to be in STA. Unfortunately,just putting the STA before the Main() (or any other sub) did not keep the service in single thread mode. So I had to create a new thread and join it like so:
Public Class CMS
Protected Overrides Sub OnStart(ByVal args() As String)
Timer1.Enabled = True
Timer1.Start()

I have an application which has 2 WebBrowser controls inside(both with script errors suppressed if thal). The application involves navigating to the same url every 3-4 seconds roughly(when the browser is ready).After a while it will crash and tell me flash.ocx is missing and is not included with this version of windows(w7 and vista). I troubleshoot the problem and tells me to update flash which does no fix the problem. This crash only happens when I run the application outside of the IDE btw and I get no errors in the IDE.
View 1 RepliesI have developed a server-client application. The program has multiple users each uniquely login in with their credentials to the system. The problem arises when the application crashes, pc shuts/restarts, the user then cannot log in as it is showing is still logged in. This is true because the last code from the program, which logs out the users , is not run because the program crashed or the pc , that is intalled on, lost power. Is there a way to go around this problem. I cannot deploy the application until this is fixed. I have placed on application exit and on last form`s closing event to logout users. It still keeps them logged in in some cases as I already stated previously.

View 6 RepliesI have an application developed in VS2008 VB.net. It is a numberpad with buttons for 0 - 9.When published and installed on my local PC, everything works as expected. I open a browser window, and am able to click a number-button and have the corrosponding number sent to the active window location. When installed on other PC's, the numbers sent to the active window location are repeated many many times. If you click the "3" button, then anywhere from 10 to 50 "3"s are sent to the screen.All PC's have Windows XP Professional, Version 2002, Service Pack 3.The only differences I can detect are the many many .NET frameworks installed on my computer and not on others.[code]

View 3 RepliesAs far as I understand from the docs, it seems that Application.Run() starts a message loop on the current thread, which in turns enables it to process user input (Is that right?).The overloaded version Application.Run(Form) basically does the same, only it exists when the form closes, and it shows the form by default.timer ticks after 20mns, and has to execute say approx. 15 tasks one by one, every time creating an instance of a progress dialog, initially hidden in the taskbar.

I have VB.Net application that has worked fine for years on XP and Windows 7. For some reason the last update I put out does not run even the simplest VB commands.Simple Environ() fails.I have tried putting simple VB commands onto a MsgBox on the start of the app and everything raises an error. I have no idea what is going on! The exact same app runs fine on Windows 7 clients. All the XP machines including a fresh XP virtual machine with the .Net 3.5 framework even gives the errors. No VB commands are working. I thought maybe something happened to my vbproj files, so I copied an older one from a couple weeks ago when things worked fine and it still does not work.

View 2 RepliesI'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?
View 2 RepliesThe fact is I'm making an application, which users can install by using a Setup file...once installed the data in the database can be updated by a centralized server. To do this, they can insert a DVD/CD-ROM and export the necessary data towards it. I need to do it that way, because some of the users who really need this data will be using stand alone computers.The application gets it's data from a mdb-file and the connection remains open as long a person works with the application (maybe not the best way to do, but I know :-) )...when the user uses the application, he can perform an export...this exports the .ini-file and pictures (which works fine), but he also needs to export the mdb behind the application...I already tried connection.close() before and connection.open() after the System.IO.File.Copy...but that doesn't seems to work.
View 2 RepliesSo 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.
