C# using C++ dll throwing exceptions

That was not what I asked for, I wish to able to throw exceptions across lannguages.

In the header (.h) I have the following declaration

extern "C" SH_API void shCreateDevice(HWND hWND) throw(...);

Which is implemented as

SH_API void shCreateDevice(HWND hWND)
{
//... CODE


if(hr == D3D_OK)
{
throw CException("failed");
}
}

In the C# application i perform as follows:

public void Initialize()
{
try {
shInitialize();
shCreateDevice(panel1.Handle);
shOnCreateDevice();
}
catch (DllNotFoundException ex){
textBox1.AppendText(ex.ToString());
} catch (EntryPointNotFoundException ex) {
textBox1.AppendText(ex.ToString());
} catch (Exception ex) {
textBox1.AppendText(ex.ToString());
}
}

However even when the if is true statement in the C++ code, exception is not catched in the C# application.

Unmanaged code is not a possiblity for this case, the C++ code is a highly optimized Volume Rendering framework based upon DirectX9 and with support for DirectX10 under the Vista beta program.
