    Use the 'ref' keyword.

    e.g., if you're calling "SomeMethod";

    SomeMethod(ref SomeArg);

    Check out the samples included in the sdk, there are some good ones demonstrating various pinvoke declarations.

    Also check out this page: http://msdn.microsoft.com/netframework/programming/interop/default.aspx

    The first few links include some great resources for dealing with platform invoke (calling C++ methods from managed code) and should be able to help you out here.

    Hi David,

    I tried using ref but then it returns an error even then.

    It tells unable to convert (data type) to *(data type)

    In that case i have to declare it as pointers. But if i do so then it becomes unsafe...

    how can this be overcome

    Thanks in advance
