Question

I have an application that programatically makes calls to different numbers. The application is written in c# (managed) and I use pInvoke for the c++ TAPI functions. Everything works fine except the fact that I need to convert the phone number to a the dialable format.

To do this conversion, I have to use the C++ function lineTranslateAddress, but from C#. Has anyone used this function from managed code and can provide me some samples or at least explanations.

Maybe some indications how to marshall / nmarshall the last field

LPLINETRANSLATEOUTPUT
lpTranslateOutput

I should also mention that the application is for a smart device.

Thanks,

I used this code example, and it works

[DllImport("coredll", SetLastError = true)]
extern public static int lineTranslateAddress(
    IntPtr hLineApp,
    int dwDeviceID,
    int dwAPIVersion,
    string lpszAddressIn,
    int dwCard,
    int dwTranslateOptions,
    byte[] lpTranslateOutput
    );
