C# - .NET Will Stop Debugging Run The Code In The Finally Block?

Well, I've read (and learned) that the finally block doesn't always execute its code (even apart from pulling the plug).FYI For more information, see try catch finally question

Code To Run On 'stop Debugging'?

Aug 25, 2010

When I end my app by pressing the stop button in visual studio, is there a way for that event to trigger some exit code? I'd rather do that than include a visually distracting quit button.

Better still would be to program some kind of key sequence, eg control + q to trigger some quit code so my app can exit cleanly. Is this possible? I wouldn't know how to program a key shortcut but it might be handy.

VS 2010 Stop A Block Of Code Executing When User Clicks "Stop"?

Mar 1, 2011

I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.

My START code is basically a while loop that iteratively does some calculations.

So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

Use Finally In A Try Block?

Apr 3, 2010

I often use the Try block to catch exeptions, and I have read in the help pages to do with the Finally statement. But, from what I understand it has no use whatsoever. Why would I use Finally instead of just ending the Try block. For example, from what I know

Set An Object To Nothing In The Finally Block?

Apr 4, 2012

In this VB.NET code:

Dim o as SomeClass
Try
o = new SomeClass
'call some method on o here
Catch(...)

Why is there a need to set o to Nothing? What if i don't set it to Nothing in the Finally block? What i think is that it is OK if you don't set it to Nothing because the object will be marked for GC.

IDE :: In Finally Block - Check If An Exception Occurred Or Not ?

Sep 18, 2011

In Finally Block, How can we check if an exception occurred or Not.I am programming in VB.Net. Why i am asking is that in the Finally Block there could be some things you would like to do if an Exception has occured and some things you want to do if an exception has not occured. So, within finally block how do we know if an exception has occured

Terminate The Application Is To Hit 'stop Debugging'?

Mar 17, 2011

I wrote the following code to build a basic game that makes two cars race (randomgenerator) and let the user pick their bets on the end results. I've gone terribly wrong somewhere in that my cars only race halfway then get stuck behind the start line and the programme keeps repeating the beeping and the messsagebox.show and adding results to the 'incorrect' box.

The only way to terminate the application is to hit 'stop debugging'.

Option Explicit On
Option Strict On

Asp.net - Opening File Via Hyperlink Causes VS To Stop Debugging?

Jun 21, 2012

This is a rather odd problem i am running into I currently have a web page that i am adding hyperlinks to that when clicked will open a file (usually Word file though there are some Excel files). Here's the problem. When debugging all of the files do open properly, however, files labeled .doc, .docx, or .xls all end up stopping debug mode when they open. I have .docm files that open properly and do not stop debugging. There isn't an error thrown anywhere just a forced stop of debug mode it seems.

Has anyone ran into a problem similar to this? I have only tested locally but i am unsure if it will cause problems when putting it on the test server. I'm still not quite done with the rest of the page so i was hoping to stop this behavior before completeing the project.

Press Stop Debugging/ Task Manager End Process?

Feb 15, 2012

When I go to Debug my program (F5), the program will load, until I click on the form with the main part of code in it, and then the program freezes, although it doesn't lock up because as soon as I press stop debugging/ task manager end process, it closes fine.

I will attach the zip of the program here. The form that it freezes on is "Black Ops". Edit Due to the forum not accepting my .Zip file (Invalid file type), I will upload it to MediaFire. Download link (445kb): Click Here

Try...Catch Block "pauses" While Debugging?

But while debugging (and "Address" field is left empty), the program breaks and I get an exception at the "Throw New Exception" line even if the error should be trapped by the "Try...Catch" block.
At runtime, everything works well and the correct error is displayed.

.net - While Debugging VB Code In VS2008?

I have a new 64 bit machine with vs2008 - is there anyway to mouseover a guid value and have it appear? What makes guid's so special that their value doesn't show like most variables?

Debugging VB 2010 & VB6 Code?

Jun 25, 2010

Prior to VS 2010 I was able to debug VB6 client code from the .Net IDE by setting "Start External Program" to vb6.exe (full path), or attaching to the running vb6 executable via "Tools->Attach to Process" and have execution stop at the required breakpoints in my .Net code.

Now with VS 2010 I seem to be only able to accomplish the same by setting the target framework to 4.

Is this a bug in VS 2010, or is there a switch/option that controls this?

C# - Use Case For Try-catch-finally With Both Catch And Finally

Feb 17, 2010

I understand how try-catch works and how try-finally works, but I find myself using those (usually) in two completely different scenarios:

try-finally (or using in C# and VB) is mostly used around some medium-sized code block that uses some resource that needs to be disposed properly.
try-catch is mostly used either

around a single statement that can fail in a very specific way or (as a catch-all) at a very high level of the application, usually directly below some user interface action.

In my experience, cases where a try-catch-finally would be appropriate, i.e., where the block in which I want to catch some particular exception is exactly the same block in which I use some disposable resource, are extremely rare. Yet, the language designers of C#, VB and Java seem to consider this to be a highly common scenario; the VB designers even think about adding catch to using.

Or am I just overly pedantic with my restrictive use of try-catch?

EDIT: To clarify: My code usually looks like this (functions unrolled for clarity):

Try
do something
Aquire Resource (e.g. get DB connection)
Try

[Code]....

which just seems to make much more sense than putting any of the two catches on the same level as finally just to avoid indentation.

Asp.net - Debugging Code In Aspx Files?

Feb 15, 2011

I am converting an old asp project to a new .NET project. Now, all vb code are inside aspx files, and we are on the process of moving all vb script from aspx files to .vb files. My problem is, I can't debug the vb script inside most of the aspx files. All my friends don't have this problem. I think the problem is with vb text editor.I am using Visual Studio 2008. Is there anyway, I can make visual studio understand that aspx files have vb script inside them.

Debugging - Handling VB.NET Events In VB6 Code?

May 12, 2009

I have some VB6 code that instantiates a class which handles events that are being raised from a VB.NET component. The VB6 is pretty straightforward:private m_eventHandler as new Collection

public sub InitSomething()
dim handler as EventHandler
set handler = new EventHandler
m_eventHandler.Add handler
m_engine.Start

[Code]...

My problem is that when I debug the VB6 program, the first time InitSomething gets called, the event will not be handled (the VB6 event handler is never entered). Subsequent calls to InitSomething does work.

Everything works as I would have expected when I run the program outside the debugger. At this point, I'm not even sure if this is something I should be worried about.It may or may not be relevant but the VB.NET was converted from a VB6 using the Visual Studio code conversion tool (and subsequently manually cleaned up).
