try catch(...) problem in VC++

[lunguIonut]

Hello everyone,

I have a VS solution with a C# windows application and a VC++ dll which exports a function.
In that function (from the dll) I have a try catch block like this:
try{
//do something
int a =0;
int b = 100/a;
//do something else
catch(...)
{
//Log this exception
}

the prblem is that the exception is caught from the C# application. The dll (which exports a function) is imported in the C# application like this:

[DllImport("Huffman", EntryPoint = "StartToArchive")]
private static extern void StartToArchive(string from, string to, StatusCallBackDelegate statusCallback);

Do you have any ideas how can the exception (error division by 0) can be managed by the try catch block from the C++ dll without throwing an error in C#?

This code is just an example. I don't look for answers like test before the third line if a != 0.

The C++ dll is unmanaged code.
