如何用程序启动一个拨号连结？

又如何得到连结已经成功或者失败的消息？

如何结束这个拨号连结。

其中“连接Internet”为你创建的拨号程序名称
winexec('rundll32.exe rnaui.dll,RnaDial '+'连接Internet',9);

我找到了一个程序，可是 DWORD ret=RasEnumEntries(NULL,NULL,NULL,&dwSize,&n);

ret返回值也是632，这个广泛流行的程序，应该不会有这么奇怪的错误。

真的不知道哪个地方配置不对劲了。

我的系统环境是win2000 专业版。

直接RasDial函数。

ras可以为你做到，相关资料楼主可以上网查一下

楼主你代码帖出来，大家帮你看看，你光说，这样错误很难解决的

MSDN资料如下：（取自MSDN2003)

DWORD RasDial(
LPRASDIALEXTENSIONS lpRasDialExtensions,
LPCTSTR lpszPhonebook,
LPRASDIALPARAMS lpRasDialParams,
DWORD dwNotifierType,
LPVOID lpvNotifier,
LPHRASCONN lphRasConn
);

Parameters
lpRasDialExtensions
[in] Pointer to a RASDIALEXTENSIONS structure that specifies a set of RasDial extended features to enable. Set this parameter to NULL if there is not a need to enable these features.

Windows Me/98/95: This parameter is ignored. On these platforms, RasDial always uses the default behaviors for the RASDIALEXTENSIONS options.


lpszPhonebook
[in] Pointer to a null-terminated string that specifies the full path and file name of a phone-book (PBK) file. If this parameter is NULL, the function uses the current default phone-book file. The default phone-book file is the one selected by the user in the User Preferences property sheet of the Dial-Up Networking dialog box.

Windows 95: This parameter should always be NULL. Dial-up networking stores phone-book entries in the registry rather than in a phone-book file.


lpRasDialParams
[in] Pointer to a RASDIALPARAMS structure that specifies calling parameters for the RAS connection. Use the RasGetEntryDialParams function to retrieve a copy of this structure for a particular phone-book entry.
The caller must set the RASDIALPARAMS structure's dwSize member to sizeof(RASDIALPARAMS) to identify the version of the structure being passed.

If the szPhoneNumber member of the RASDIALPARAMS structure is an empty string, RasDial uses the phone number stored in the phone-book entry.

dwNotifierType
[in] Specifies the nature of the lpvNotifier parameter. If lpvNotifier is NULL, dwNotifierType is ignored. If lpvNotifier is not NULL, set dwNotifierType to one of the following values. Value Meaning
DWORD The lpvNotifier parameter is a handle to a window to receive progress notification messages. In a progress notification message, wParam is the equivalent of the rasconnstate parameter of RasDialFunc and RasDialFunc1, and lParam is the equivalent of the dwError parameter of RasDialFunc and RasDialFunc1.
The progress notification message uses a system registered message code. You can obtain the value of this message code as follows:

{UINT unMsg =
RegisterWindowMessageA( RASDIALEVENT );
if (unMsg == 0)
unMsg = WM_RASDIALEVENT;
}

0 The lpvNotifier parameter points to a RasDialFunc callback function.
1 The lpvNotifier parameter points to a RasDialFunc1 callback function.
2 The lpvNotifier parameter points to a RasDialFunc2 callback function.

Windows Me/98/95: This value is not supported.



lpvNotifier
[in] Specifies a window handle or a RasDialFunc, RasDialFunc1, or RasDialFunc2 callback function to receive RasDial event notifications. The dwNotifierType parameter specifies the nature of lpvNotifier. Please refer to its description preceding for further detail.
If this parameter is not NULL, RasDial sends the window a message, or calls the callback function, for each RasDial event. Additionally, the RasDial call operates asynchronously: RasDial returns immediately, before the connection is established, and communicates its progress via the window or callback function.

If lpvNotifier is NULL, the RasDial call operates synchronously: RasDial does not return until the connection attempt has completed successfully or failed.

If lpvNotifier is not NULL, notifications to the window or callback function can occur at any time after the initial call to RasDial. Notifications end when one of the following events occurs:


The connection is established. In other words, the RAS connection state is RASCS_Connected.
The connection fails. In other words, dwError is nonzero.
RasHangUp is called on the connection.
The callback notifications are made in the context of a thread captured during the initial call to RasDial.

lphRasConn
[in] Pointer to a variable of type HRASCONN. Set the HRASCONN variable to NULL before calling RasDial. If RasDial succeeds, it stores a handle to the RAS connection into *lphRasConn.
Return Values
If the function succeeds, the immediate return value is zero. In addition, the function stores a handle to the RAS connection into the variable pointed to by lphRasConn.

If the function fails, the immediate return value is a nonzero error value, either from the set listed in the RasError.h header file or ERROR_NOT_ENOUGH_MEMORY.
