[高分]window mobile5 中操作通讯录,该如何解决

[高分]window mobile5 中操作通讯录
用vs2005（C++）写一个程序，在mobile5中能把数据按通讯录的格式导入数据到通讯录里。
请教各位大虾，如何实现，有哪些函数或方法


------解决方案--------------------
你的代码里面“polApp”是个空值，怎么可能继续走下去呢？你可以用下面的代码初始化
BOOL InitPoom(HWND hwnd)
{
BOOL bSuccess = FALSE;

if (SUCCEEDED(CoInitializeEx( NULL, 0)))
{
// Now, let 's get the main outlook application
if (SUCCEEDED(CoCreateInstance(CLSID_Application, NULL, CLSCTX_INPROC_SERVER,
IID_IPOutlookApp, reinterpret_cast <void **> (&g_polApp))))
{

// login to the Pocket Outlook object model
if(SUCCEEDED(g_polApp-> Logon(NULL)))
{
// can 't login to the app
bSuccess = TRUE;
}
}

}

return bSuccess;
}

D:\Program Files\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Samples\CPP\Win32

其实在你WM5.0的目录下有很多例子可以参考，poom的操作你可以参考Poommaster里的Poomdata.cpp
