    Resolved Type Conversion

    The type of a picture box handle is IntPtr. Firstly what does 'Ptr' stand for?

    How do i convert this to an int?

    I have tried picCamA.Handle.ToInt32 but the SendMessage API wants an int, not an Int32.

    I think you should change the declaration of SendMEssage API to use IntPtr rather than int. This is how it should work in .NET
    Use [code] source code here[/code] tags when you post source code.

    Just as Shuja Ali says. Any API function that wants a handle should have the argument declared as IntPtr. From the help:
    A platform-specific type that is used to represent a pointer or a handle.
