Exceptions Must Be Exclusive - Exceptions Will Ever Occur Simultaneously ?

Dec 26, 2009

I've just skipped around a few inbuilt VB classes' methods which throws exception. of all that i've came across, methods may throw multiple exceptions but ALL of them are exclusive, meaning there is no way 2 exceptions will ever occur simultaneously, yea and i was trying to make my class throw 2 exceptions simultaneously, hence this question, must all exceptions be exclusive?

Turn Off And Turn On Background Music In Program

Feb 17, 2012

Right now I can add background music in my program by using this code

My.Computer.Audio.Play(My.Resources.Music_3, AudioPlayMode.Background)

I can also turn it off and change the music by using this code

My.Computer.Audio.Stop()
My.Computer.Audio.Play(My.Resources.Another_Music, AudioPlayMode.BackgroundLoop)

Is it possible to pause the music then if I resume the music it will just continue the flow? I mean if I pause the background music in 33 seconds and the music has 50 seconds and I resume it will just continue playing in 33,34,35 etc.. seconds?

Communications :: Send A Command Via RS232 Communications

Jan 26, 2009

I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.

How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.

I am using this code currently without the start and end bits

Log Exceptions In VB, On An ASP.NET Application?

Apr 6, 2009

I'm working on an ASP.NET web application, written using Visual Basic, and I'm trying to track down an error message that I'm getting.I'd like to get it to log the exception to a file (or the event log) so I can see it, as the error only occurs on the production server, and not on the development environment (therefore VS isn't installed on there...).

Does anyone have any thoughts as to best practice as to how to do this ?

Swallowing All Exceptions

Dec 25, 2010

Why is the net filled with examples like this? Why do people just chuck try catch around any expression with out the slightest thought about pre-validation?

i would never just add try catch and not handle the exception. I tell people this is basically on error resume next in disguise.

Is an exception ever unimportant to just use try catch but with out any message?I really want to progress as a programmer but have i been approaching all this wrong?

Catching Exceptions In Soapclient?

Feb 24, 2012

Take the TripPriceService.wsdl from this link Add a service reference(ServiceReference1) to a windows application, by giving the wsdl from the mentioned wsdl file saved in local folder. My question has two parts

1) Is the below fault message a valid soap fault as per the wsdl(TripPriceServiceException)?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:trip="http://trip.price.service">
<soapenv:Header/>
<soapenv:Body>

[code]....

2)Now How to handle and catch the detail tag, when the response is a soap:fault?

Imports windowsapp1.ServiceReference1
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim obj As New ServiceReference1.TripPriceServiceFacadeClient

[code]....

The line obj.getTripPrice, invokes the service. However will it throw an exception if the response is a soap fault(of type TripPriceServiceException)? How to handle such cases, do we need to use ServiceReference1.TripPriceServiceException? We are in a need to handle such faults in our webservice client.

Exceptions In Class Libraries?

Dec 6, 2009

I'm creating a class library that contains a series of functions with Try...Catch blocks to handle errors. When i run another application that uses the class library, and call a function in the library using parameters that i know should cause an error (i.e. divide by zero), i don't get an exception thrown.

Can you not use Try.. Catch blocks in external libraries? If not, how are you suppose to handle errors in these functions?

Get More Detail Of First Chance Exceptions?

Mar 16, 2012

Is there a way to configure the debugger or write code in such a way as to get more information when first chance exceptions happen? I understand they are generally not harmful and I do quite a bit of exception handling in code but when I'm doing database operations it's to know when first chance exceptions occur. Of course I can see them in the Immediate Window in VS but I would like a full stack trace, not ust a line saying "A first chance exception..."

Getting First Chance Exceptions Stop My App

Jan 15, 2011

When an exception is thrown in my app, I expect the debugger to stop running and enter debugging mode, but it does not. Instead, I just get a message in the Immediate Window ('A first chance exception ...'), and the program keeps on running like if nothing happened. However, the sub (in which the exception was thrown) is exited, so statements after the exception are not executed. Since this sub makes the initialization of my program, running becomes very unstable.How can I tell the debugger to stop execution when an exception is thrown? On the 'Advenced compile options' page I don't have 'Target CPU'. Maybe it's that I have only VB Express?If I tick the 'Thrown' checkbox in Debug > Exceptions, execution stops even if I have a catch for that exception, and I don't want that.Until now I used VB 2008 on 32 bit, and everything worked fine, but since I moved to 2010 64 bit I just can't get it right.

ll app build in VB 2005 that has a DLL. The app runs fine on 32bit systems but fails on 64-bit ones (Failed to load the assembly: BadImageFormat from the DLL). As I could not fix the problem I wish to somehow ignore this error so the rest of the app can run normally. I wish to retain the funcionality on 32-bit systems thus not removing the DLL from the project.

Try / Catch Not Trapping Exceptions

Mar 25, 2011

I am working on an app that uses a third-party charting component.It is a .Net component. There have been some occasions when exceptions have occurred inside the third-party component code, but my try/catch is not trapping them.Should they get trapped?My code is structured roughly like this:[code]I have since found and fixed what was causing the exceptions, but I would have thought that this should trap them. What happens when I run in the IDE is that it crashes and Visual Studio throws up a page telling me there is no code available to debug, and no disassembly available.Fair enough, but I repeat - why doesn't the exception get trapped?
