.net - Calling New StackTrace Blocks When Closing Application

Sep 12, 2011

I just did some analysis by using a global function which is called GetCallingMethod in my case.

Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.

In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.

This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.

Closing Application Via X Button Without Closing Forms Inside Mdiparent Causes Exception Error

May 3, 2010

Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll

Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

StackTrace And StackFrame Events?

Sep 21, 2009

For debugging purposes, I would like to create a log file showing each function that gets entered. I understand everytime a function is entered, it is added to the stack trace. Is it possible to get events from the stacktrace everytime a new function gets added so that I can log it? I don't want to write log messages to every one of my functions in code, I would like to automate it. OR, is there another way? (I am using VB 2008 Pro)

Application Not Closing Correctly

Nov 12, 2011

I'm having a problem over here; I'm developing a DirectX 9 application, and for some reason, I can't figure the way to close the application completely. This has never happened to me, to be honest. I am using Application.Exit(), which doesn't seem to do anything - it just closes the form, but the program is still running. I have also tried End, but it throws a run-time error I can't seem to figure out.

Checking For And Closing An Application?

Aug 15, 2011

checking if an application is open and then closing it if it is... For an example, I'll use paint or notepad...

Does something like this work?
Dim myProcess As Process = New Process
myProcess.StartInfo.FileName = "PaintDotNet.exe"

[Code]....

What is the best way to check if an application is open first? Struggling with that portion.

How Could Application Form In Vb Be Closing By Itself

Feb 24, 2012

I have a form in a Pocket PC app that is set to be the Application form using:Application.Run(New frmMain())Somehow this form is getting closed for no reason while working on another form. No closing event is fired and nowhere in my code can you close the main form anyway. It is only closed by clicking the OK button at the top right of the window. When this is clicked, the user is prompted if he/she really wants to close the application. However, this is not occurring either.Basically, I am on another form which adds a new record to the database. After adding the record the gotFocus event is somehow called for frmMain. When the code in the gotFocus event reaches a reference to a control on the form, there is an exception that states that the object is disposed.

VS 02/03 - Closing A Word Document & Application

Jun 30, 2009

I'm busy with a program which assists me with all my exams, right, now, with this program I'm launching each program associated with each exam. After the document / spreadsheet etc. is shown, I mark what I need to, then, I have a button which closes the current process, and returns me to my default application interface. All this is working, except for the .doc files, Word files.

Everytime I launch word, I get the Document recovery pane.

I've tried the following: [Code]

As a last resort ( and this doesn't work ), because WordDocument.close does not work, Word Application. Quit does not work! By, saying it doesn't work, means it closes everything, yes, but the Document Recovery PAne always shows up, and I can't understand why! Is there some way of disabling it completely
I know some will say it is not a good idea, I know, I know I really need to get rid of it.

VS 2010 Closing Application Not Just Form?

Jun 11, 2012

How can I ensure an application is fully closed when the user selects the close window X at the top of the form. It appears to just close the current form by default which is leaving the program still loaded in memory when the user thinks they have closed it. I have tried capturing the close and running application.exit but this closes the whole application even when I only want the current form closed.

VS 2010 Remote Closing Application

Feb 28, 2011

I have an app that is on a network drive. Around 100 people will be using the app.

Right now, I have 2 people testing it. They found a couple of bugs, I fixed them, and made the changes.

However, before I could update the app, they had to close it because I can't delete a file that is in use.

how I might prompt the user that the app will be closing in "x" amount of seconds for updating?

Blue Screen When Closing VB10 Application?

Mar 8, 2012

I am developing a simple application in VB10 that uses ADO.net to store data in an Access database, and gets input via a serial port RS232. It works well, but is not fully debugged. Unfortunately, a problem has recently started where as soon as i close the program I get a blue screen. Makes it hard to debug. The solution does not even have to have run; it just has to have been loaded and then exit VB10. The blue screen aslo happens to most of the other example solutions that I have downloaded.

Questions:

1)How do you capture the STOP error codes (probably stupid question)?

2) Is there an easy solution that rings a bell? My IT support is trying but not getting anywhere. Have to believe it is hardware related, but the hard drive checks out with testing.

Closing Child Form Closes Application?

Aug 16, 2011

I've made a Windows Forms Application that runs fine. It has some buttons that open child forms, which can simply close again without any problem. As I need the form to be in a dll, I changed the application type to a class library and added an extra project containing an exe-file that only references the main form in the dll and shows it. So far so good...

The main form is basically a tabcontrol with a bunch of controls, buttons among others. Five buttons on different tabs use the same handler to open a child form. When I click the button on the first tab everything works fine. The form opens and when it closes, only the child closes. When I click any of the buttons on the other tabs, the child form opens and when it closes again, both the child and the main form close...

I am stumped, especially since all buttons use the same code to open the child form and everything appears to be completely identical, yet the results are not. Below I have pasted the code that opens the main and child forms. I am undoubtedly not looking in the right place, but I also have no idea where to look anymore, let alone what to look for...

The code opening the main form:
Public Sub StartProgram()
'Load the form and show it
Dim frmProgram As frmMain = New frmMain

Loaded PDF In AxAcroPDF Crashes When Closing My Application

Jan 14, 2009

I have a small application (in VB.NET 2008) which gives the user the option to open a PDF document. This document is stored on a mapped network drive and is loaded in to the AxAcroPDF Control.

When closing my application I get the following message

The instruction at "0x0700609c" referenced memory at "0x00000014". The memory could not be read.

I've been google-ing this error message, but seen only a lot of problems, but no solutions.

I also tried using the WebBrowser Control, but this gives the same error.

I added synclock in datareceived and in form_closing.Within synclock in form_closing I removed datareceived handler.

Stop Application Closing Until Backgroundworker Finished?

How can I stop my application quitting until a backgroundworker has finished? Its an updater, so basically I want the form to hide until the download is finished, and then exit.I've tried to make a setting to tell the app when it is still downloading, and on form closing check this variable, but it won't work. For some reason it still quits!The update window is in a separate form to the main form, so the user clicks 'Finish', the update form closes and the main form stays open.[code]
