I am referencing my project to an external DLL which I got from a hardware vendor and encountered this error:
Exception thrown: 'System.FormatException' in mscorlib.dll
Exception thrown: 'System.FormatException' in mscorlib.dll
Exception thrown: 'System.FormatException' in Microsoft.VisualBasic.dll
Exception thrown: 'System.InvalidCastException' in Microsoft.VisualBasic.dll
An unhandled exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Additional information: Conversion from string "8010001D" to type 'Integer' is not valid.
However there is no compilation error in Visual Studio 2017, only runtime crash. A colleague could debug it fine in Visual Studio 2012. I have tried to change the targeted platfrom from .NET 2.0 to .NET 4.5 but still failed.
Here is the source code. At the moment I am just trying to see if the referencing is fine or not but it shouldn't have any problem IMO.
class Program
{
static void Main(string[] args)
{
MyKad reader = new MyKad(); //the app breaks here. MyKad() is a dll object
Console.WriteLine("Testing app starts..");
if(reader.Connect())
{
Console.WriteLine("Obj creation succeed");
}
else
{
Console.WriteLine("Obj creation failed");
}
}
}
MyKad() is from dll. I can see the methods info but not the actual code. Did I miss any legacy settings in the project configurations?
Below is the callstack
Microsoft.VisualBasic.dll!Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger( Value) Line 788 + 0x84 bytes Basic
CSMyKad.dll!CSMyKad.MyKad.UserControl_Initialize() + 0x73 bytes
CSMyKad.dll!CSMyKad.MyKad.MyKad() + 0x11e bytes

We have a Windows 10 UWP app that runs fine under Debug builds and crashes under Release builds. What it is about release builds that makes it crash is that .NET Native tools chain is enabled - disabling that allows the app to run. But that's not a real fix as it needs to run with .NET Native tool chain if you intend to publish to the store.
We use Microsoft.Practices.Unity for DI. Here's an example of how we register some classes:
container.RegisterType<IBoardView, BoardView>();
And then, in our app we resolve it as follows:
container.Resolve<IBoardView>();
It works fine unless I run it with .NET Native, in which case I get the following exception:
An exception of type 'Microsoft.Practices.Unity.ResolutionFailedException' occurred in Microsoft.Practices.Unity.dll but was not handled in user code
Additional information: Resolution of the dependency failed, type = "WindowsUniversal.ViewModels.Interfaces.IBoardViewModel", name = "(none)".
Exception occurred while: while resolving.
And in the output window I get:
Exception thrown: 'System.NullReferenceException' in System.Linq.Expressions.dll
Exception thrown: 'System.NullReferenceException' in Microsoft.Practices.Unity.dll
Exception thrown: 'Microsoft.Practices.Unity.ResolutionFailedException' in Microsoft.Practices.Unity.dll
An exception of type 'Microsoft.Practices.Unity.ResolutionFailedException' occurred in Microsoft.Practices.Unity.dll but was not handled in user code
Additional information: Resolution of the dependency failed, type = "WindowsUniversal.ViewModels.Interfaces.IBoardViewModel", name = "(none)".
Exception occurred while: while resolving.
Exception is: NullReferenceException - Object reference not set to an instance of an object.
At the time of the exception, the container was:
Resolving WindowsUniversal.ViewModels.Interfaces.IBoardViewModel,(none)
All this works under Debug or Release when .NET Native is disabled. Now I know .NET Native has it's limitations, reflection being one of them. I guess I'm asking how to get around this?
Any insights would be greatly appreciated, thanks.
I have trouble running unit test on one of my machine, the test app just shut down after few seconds. Here is the output show when debugging the test:

Those exceptions is not related to my app at all, as my app dont need internet and the code in test method is not reached. They are from the test framework.
The same solution run test fine on every other machine (same Windows 10 build). I think the problem is that the system on troubled machine turn off some services required for unit testing. I cant find any thing related anywhere. What should I do to fix that, I dont want to re-install Windows.
Seems like the connection with the Test Emulator can't be established. When you build the TestApp make sure that you have set the Build configuration to Debug - Any CPU (not ARM)
Also, you shouldn't run the test project by hitting F5 but run the tests from the TestExplorer.
I end up reinstall VS 2015 and the problem now gone.
After I use my code when Ranorex is installed is works fine, but after uninstalled it, I have a library of Ranorex payed version, but I don't install it on my PC, just I need the library. there an exception showed with this line of code
Form form = Host.Local.FindSingle<Ranorex.Form>("form[#processname='" + pr.ProcessName + "']");
On debug Mode shows ;
'Host.Local' threw an exception of type 'System.TypeInitializationException'
Exception :
Exception thrown: 'System.TypeInitializationException' in Ranorex.Core.dll
Additional information: The type initializer for
'Ranorex.Core.ElementEngine' threw an exception.
For Ranorex and it's components to work atleast Ranorex Runtime Licencse is required.
I'm trying to convert my system from matlab 2012a x64 to matlab 2014b x64. However I'm getting this error. i'm using .Net 4.5, visual studio 2012 + update 5.
A first chance exception of type 'System.Exception' occurred in MWArray.dll
Additional information: Start-up options discovered in multiple assembiles.
then I hit F5 and I get:
A first chance exception of type 'System.TypeInitializationException' occurred in MWArray.dll
Additional information: The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception.
I press F5 again and I get:
A first chance exception of type 'System.TypeInitializationException' occurred in MWArray.dll
Additional information: The type initializer for 'MathWorks.MATLAB.NET.Arrays.MWArray' threw an exception.
here is my code:
private static MWArray ConvertBlackLevelResultsToMWArray(BlackLevelData blackLevelData)
{
var blackLevelResultsGroupedbyExposure = from blResult in blackLevelData group blResult by blResult.ExposureTime;
var exposuresCount = blackLevelResultsGroupedbyExposure.Count();
var blackLevelCells = new MWCellArray(1, exposuresCount); //the exception is here
I have used .net reflector in order to go over all of the dependencies in other DLL files, they all have refernce to the correct MWarray version 2.14.1.0
Can you suggest A way to find out what is my problem?
thanks
You must remove all the attributes
[assembly: MathWorks.MATLAB.NET.Utility.MWMCROption ("- nojit")]
from all places, to which were added for MCR 2012a.
I am using sample from https://github.com/liveservices/LiveSDK but it isn't working. I managed to run the PhotoSkyOnTheGo project, but after logging in I get 3 exceptions:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.dll
What am I doing wrong or what source code should I use?
