Application Does Not Crash On Runtime Errors
Mar 31, 2012
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 have a project that as a standalone runs perfectly. There are a number of routines, forms etc. that I want to incorporate into another solution that I have created. Each time I try, it will load in the new project, but if I try to access anything by clicking on it, one of two things happens, either VS crashes and then restarts OR I get 100+ designer errors thrown.

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 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.

I 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.

I 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.

I'm making a project for school with a group of classmates. It is an application that needs to reference quite a few pictures and strings from My.Resources. I don't know what the problem is but, whenever I run the program, I get a message that reads this: "There were several build errors. Would you like to continue and run the last successful build?"
And then below in the Output:
----- Build started: Project: Wilkes-Barre Virtual Scavenger hunt, Configuration: Debug x86 ------
COM Reference 'WMPLib' is the interop assembly for ActiveX control 'AxWMPLib' but was marked to be linked by the compiler with the /link flag. This COM reference will be treated as a reference and will not be linked.

I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />
</customErrors>

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 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.
