Pocket PC Development:: Device Reading and Writing

[bicphuong]

Dear CodeProject Users, I have programmed some Windows Mobile applications with C# and VB.NET for my Pocket PC. I think it's simple. When I want to read and write contacts from SIM and call log, I got problems because C# do not support (I think so). But C++ is supported with many API (refer to Windows Mobile 5 SDK help) I'm wondering how can we use these API in C# or VB.NET ? OR How can we start with C++ Programming for Windows Mobile step by step ? Thanks for your attention, Phuong
