Unhandled exception occurs after handling exception


Unhandled exception occurs after handling exception

Hope this helps In your handler method, you need to tell .NET that you handled the exception. Otherwise it will still kill the application. You do this by using the Handled property of the DispatcherUnhandledExceptionEventArgs object.
So if you decide that you want to continue the application despite the exception, set it to true:
code :
private void App_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
{
    e.Handled = true; //let's continue and see if anything explodes
}

around this issue That depends on what you keep in the session. In most cases it won't be good to log user out just because there's an error in your code. Make a custom error page, and redirect there, so user can spam refresh on the error page as long as he wants.

will be helpful for those in need in webkit (what chrome or safari uses) debug tools, click the Scripts section on the top. then look for hexagon like icon on the bottom with the two vertical lines. clicking that will cause javascript execution to pause on an error. At the right you will see the callstack, where you can trace through everything.

Hope this helps You need to attach an event handler to UnhandledException event on the Current AppDomain:
AppDomain.CurrentDomain.UnhandledException += UnhandledExceptionHandler
Unhandled exception occurs when I try to do cleanup for STL vectors

Unhandled exception occurs when I try to do cleanup for STL vectors

To fix this issue The reason for the crash: you define vector, fill your vector with ee.assign( 13, L”-1” ); and with wchar_t *temp = new wchar_t[50]; and delete with delete[]. All mismatched.
delete[] operator frees memory allocated on the heap ee.assign( 13, L”-1” ); passes compiler allocated objects. That is wrong. These are not on the heap and you shouldn't free that memory, but you do that when you call delete[].
code :
std::vector<std::wstring> v;
v.assign(10,L"xyz");
std::wstring s = L"abc";
v.push_back(s);
... etc.
v.clear(); // call destructor for every std::wstring in the vector
wchar_t temp[50];
GetDlgItemTxt( ... , temp, ... );
v[i] = temp; // creates a wstring object and copies temp in there
vector<wchar_t*> v;
v.assign(10, 0); // fill in with null pointers
wchar_t *ptr = new wchar_t[10];
... fill in ptr memory with data
v.push_back(ptr);
... etc.
// Now you need to free memory you allocated manually - You do not do that
// in case of std::vector<std::wstring>
for (vector<wchar_t*>::iterator it = v.begin(); it != v.end(); ++it)
    delete[] *it;

v.clear(); // clear function calls destructor for every object in the vector.
// There is no destructor for a pointer, hence the difference between
// deallocating vector<wstring> and vector<wchar_t*>
Unhandled exception error occurs after 10 seconds, why?

it should still fix some issue I found some interesting infos, looks like try catch won't do anything for you, as it is probably the amount of graphics you are asking c# to generate. You have to lower the quality of the graphics your displaying or reducing the amount of objects that require graphics in your code, see :
System.ComponentModel.Win32Exception: The operation completed successfully
