.net - Unhandled Exception From Dll - Only Shows Up In Release Build
Apr 11, 2012
I have a dll library that I built to help reduce the amount of boilerplate code copied over from project to project. There is a timer running in the dll to maintain the connection to our machinery via RPC. When I debug my project and break the RPC connection my code gracefully tosses a disconnect event from the dll library and my main form catches the event and handles it appropriately.Now, build for release. When I break the RPC connection a unhandled exception is tossed from the library that apparently is not caught elsewhere.
The weird part is that the code that is throwing the exception is in the timer and the calls are all wrapped in try/catch blocks and the catch block swallows the exception and does other cleanup work.I don't get how in debug mode everything is fine but in release it is not. That part doesn't make sense to me. I tried looking at the exception object and setting a handled property on it but it's not available. Is this normal behavior what I am seeing?
I just recently started utilizing numerous libraries in my projects to keep my solutions more trimmed and easy to follow. Hopefully this isn't a problem with libraries I had not considered.

I have a Form with a Media Player in it. Which plays a Song.
[Code]...
It's playing in the background since the Form is hidden. When I play itin Debug, everything works fine. When I run the app outside Debug, I get this error: [URL] The Music File is there, but strangely, there comes this weird error.

I am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?

I have some very simple questions about making a release build exe in vb.net using MS VB 2010 Express.
I realize that my project's executable is built in the bin/debug folder. However, when I copy this to any other location on my computer or someone else's, this executable does not function. I have read that I need to create a release build but in MS VB 2010 Express, when I use the Project-Properties menu and change the Compile tab configuration to Release and the path to binRelease, I still get the exe in the binDebug folder and not the binRelease folder.
1) Is it normal that exe's from the debug folder do not function outside of the debug folder?
2) Most importantly, if the release build produces a faster exe, could someone please explain step by step how to do this with MS VB 2010 Express ? I do not see any button on the compile tab in the project properties that actually builds the release.

I wrote a little (like 40 lines little) Winforms application with VB.net in Visual Studio 2010. Now I've released the code as a Google Code project. It's easy for a developer to get the source but I'd like to make it easy to install too.
What I did was make a release build then zip up what it created, this included a setup.exe. There was also an option to "publish" my project which looks like it can enable update checks and other stuff.

I have a form and I drag and drop a control in VB.NET. I have a line say,
private WithEvents radioButton RadioButton
Also, I have a handler like,
private void click(.....) Handles radioButton.Click {
...
}
Now, When I build this is .NET 3.5 in release mode, and see the generated code in reflector tool, the code is something like:
Private Overridable Property radioButton As RadioButton
.
.
.
<AccessedThroughProperty("radioButton")> _
Private _radioButton As RadioButton
And how do I avoid the generation of new properties and fields?

I've searched the VS settings and haven't discovered why the bin.Release folder is empty after a build. The bin.Debug folder output is normal. The same occurs with the obj.* folder.

Every time I compile a new release build in vb.net 2009, the file version number of my main exe is correct, but the assembly version number is the same as the last build instead of the current version even though I manually change the file and assembly version in the design studio to be the same prior to compiling.The only way I can get the assembly version to be correct is to close Visual Studio and delete the obj folder. Then if I open the solution and recompile, all is well.
Here is the information copied from the About box in VS:
Microsoft Visual Studio 2008
Version 9.0.30729.1 SP
Microsoft .NET Framework

I have one global generic exception handler(catch ex as Exception) for all unhandled exceptions from application.But in debug mode(app runs from VS) I don`t want that exceptions go to this global handler.Better for me is when VS stops app on place when exception occurs.

I was scripting a very basic process manager, with a ListView component, and it was working fine for many days, up until now.Here is the code for getting processes:
Dim Process As New Process()
Dim Count As Integer = 0
ListView1.Items.Clear()[code].....
The line of code where I put "*WIN32 EXCEPTION LINE* keeps running into an error(Win32 Exception was unhandled; Access is denied). Here is the full error description:
System.ComponentModel.Win32Exception was unhandled
ErrorCode=-2147467259
Message=Access is denied[code]....
As I said before, this had been working for several days, up until now.

Using MS Visual Studio 2010 Express, when trying to debug, the build finishes and the following error below appears. It doesn't seem to effect the running of the program.
The error is:
An exception was encountered while constructing the content of this frame. This information is also logged by running the application with the /log parameter on the command line, which stores results in "C:Documents and SettingsCorkyApplication
DataMicrosoftVBExpress10.0ActivityLog.xml".
Exception details:
System.Runtime.InteropServices.COMException (0x80040154): Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))[code].....
I can't find the "ActivityLog.xml" file the message references.

I got an out of memory exception in a photo editor thingy i was making in vb.net. The bitmap image is constantly changing, and I always Dispose() of it after it has been sent off to the other bitmap. Is it being stored in a temp folder and using up all my space on the computer, or what? It always bugs after about 8 bitmaps have been drawn.

I have the following sub where i am reading in a 250mb file of dictionary words in a list, for example
Aardvark
Because
Count
[Code]....
As you can see i am wanting to use linq to remove duplicates, and also because i want to use the union and except statments elsewhere.
The above is fine if the filesize is about 150mb but with 250mb it throws a out of memory unhandled exception, on 'sWriter.Writeline(sline).
I am thinking this would need to be inside the loop, but cant work out how include my linq statement also.

I've been using it for three days, and tried to make my own application. Everything was going okay, it ran fine in the debugger and everything worked, so I assumed there would be no problems. But then when I went to run it from the exe in the folder, it shows me this:
Quote:
System.Threading.ThreadStateException: Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.

I copied what I think to be the most important part of it. I've been searching around, and it says to do something with the main method, but I have no idea what that means.
