c# wince 禁止gprs/wcdma拨号时候弹出密码输入框

有时候写程序需要直接把SIM卡用户名密码写入程序，这样方便省事，直接启动就行了，免得麻烦。

如下类，直接拨号前调用一下set()函数就可以了，已测试是OK的

public class wcdmaset

{

public static void set()

{

RASENTRY rasEntry = new RASENTRY();

//RASDIALPARAMS RasDialParams = new RASDIALPARAMS(); ;

int dwSize = Marshal.SizeOf(rasEntry);

byte[] lpb = new byte[1024];

int lpbSize = lpb.Length;

int ret = -1;

//初始化

rasEntry.dwSize = dwSize;

ret = RasGetEntryProperties(null, "WCDMA", ref rasEntry, ref dwSize, lpb, ref lpbSize);

if (ret == 0)

{

rasEntry.dwfOptions &= ~RASEO_PreviewUserPw;

ret = RasSetEntryProperties(null, "WCDMA", ref rasEntry, rasEntry.dwSize, 0, 0);

// ret = RasSetEntryProperties(null, entryName, ref rasEntry, rasEntry.dwSize, lpb, lpbSize);

}

}
