I am using OpenCV 2.4.6 with VS2012 c++/cli in Windows 8 and trying to simply read a matrix from a file. At runtime, I am crashing when I try and open the file and I am getting an error saying "System.Runtime.InteropServices.SEHException" - "External component has thrown an exception".

I have two questions: 1) what is causing this error; and 2) why is try/catch not handling this error?

My code looks like:

private: System::Void buttonLoadStyle_Click(System::Object^  sender, System::EventArgs^  e) {
FileStorage fs;
try
{
}
catch(cv::Exception& e)
{
const char * err_msg = e.what();
}
catch(...)
{
}

if(fs.isOpened())
{
// do something
}
};


I get the exception when the the fs.open line tries to open the file. Further, the exception is not caught by my try/catch blocks.

Any help greatly appreciated. Thanks

Edit: When I remove the ".xml" extension, I execute past the fs.open line but, of course, do not find the file. Seems like it might be something with parsing the filename.

Any help greatly appreciated. Thanks
