Q2：如何从winCE 5.0设备读取短信。 [英] Q2: how to read SMS from winCE 5.0 device.?
问题描述
我想在VC ++ .net中开发一个应用程序，它从PND71C_EN（ARMV4I）设备读取短信。
我试过以下代码来阅读短信
代码：
// THREADSTRUCT * ts =（THREADSTRUCT *）pArg;
//THREADSTRUCT* ts = (THREADSTRUCT*)pArg;
  SMS_ADDRESS smsaDestination;
SMS_ADDRESS smsaDestination;
  TEXT_PROVIDER_SPECIFIC_DATA tpsd;
TEXT_PROVIDER_SPECIFIC_DATA tpsd;
  SMS_HANDLE smshHandle;
SMS_HANDLE smshHandle;
  HANDLE hRead = CreateEvent（NULL，FALSE，FALSE，NULL）;
HANDLE hRead = CreateEvent (NULL, FALSE, FALSE, NULL);
  //打开短信处理
// Open an SMS Handle
  HRESULT HR = SmsOpen（SMS_MSGTYPE_TEXT，SMS_MODE_RECEIVE，
HRESULT hr = SmsOpen (SMS_MSGTYPE_TEXT, SMS_MODE_RECEIVE,
             &安培; smshHandle， & hRead）;
&smshHandle, &hRead);
  if（hr！= ERROR_SUCCESS）{
if (hr != ERROR_SUCCESS) {
            返回0;
return 0;
  }
}
  //等待邮件进来。
// Wait for message to come in.
  int rc = WaitForSingleObject（hRead，30000）;
int rc = WaitForSingleObject (hRead, 30000);
  if（rc！= WAIT_OBJECT_0）{
if (rc != WAIT_OBJECT_0) {
    SmsClose（smshHandle）;
SmsClose (smshHandle);
     返回0;
return 0;
  }
}
  memset（& smsaDestination，0，sizeof（smsaDestination））;
memset (&smsaDestination, 0, sizeof (smsaDestination));
  DWORD dwSize，dwRead = 0;
DWORD dwSize, dwRead = 0;
  hr = SmsGetMessageSize（smshHandle，& dwSize）;
hr = SmsGetMessageSize (smshHandle, &dwSize);
  if（hr！= ERROR_SUCCESS）{
if (hr != ERROR_SUCCESS) {
      dwSize = 1024;
dwSize = 1024;
     返回0;
return 0;
  }
}
  char * pMessage =（char *）malloc（dwSize + 1）;
char *pMessage = (char *)malloc (dwSize+1);
  memset（& tpsd，0，sizeof（tpsd））;
memset (&tpsd, 0, sizeof (tpsd));
  HR = SmsReadMessage（smshHandle，NULL，&安培; smsaDestination，NULL，
hr = SmsReadMessage (smshHandle, NULL, &smsaDestination, NULL,
            &NBSP ;（PBYTE）pMessage，的dwSize，
(PBYTE)pMessage, dwSize,
             （PBYTE）及tpsd，的sizeof（TEXT_PROVIDER_SPECIFIC_DATA），
(PBYTE)&tpsd, sizeof(TEXT_PROVIDER_SPECIFIC_DATA),
             &安培; dwRead）;
&dwRead);
  if（hr == ERROR_SUCCESS）{
if (hr == ERROR_SUCCESS) {
      CString outputStr;
CString outputStr;
      outputStr.Format（L" dst =％s，msg =％s"，smsaDestination.ptsAddress，pMessage）;
outputStr.Format(L"dst=%s,msg=%s",smsaDestination.ptsAddress,pMessage);
      AfxMessageBox（outputStr）;
AfxMessageBox(outputStr);
  } else
} else
       免费（pMessage）;
free (pMessage);
  SmsClose（smshHandle）;
SmsClose (smshHandle);
    返回0;
return 0;

错误：
但是在我编译项目时给了我以下错误，尽管我已经包含了"sms.h"和"sms.h"。标题
错误 1
错误LNK2019：未解决函数"unsigned long __cdecl ThreadRecordMsg（void）"中引用的外部符号SmsReadMessage （？ThreadRecordMsg @@ YAKXZ）的
Smsreceiver2Dlg.obj的 Smsreceiver2
Error 1 error LNK2019: unresolved external symbol SmsReadMessage referenced in function "unsigned long __cdecl ThreadRecordMsg(void)" (?ThreadRecordMsg@@YAKXZ) Smsreceiver2Dlg.obj Smsreceiver2
错误LNK2019：未解析的外部符号SmsGetMessageSize在函数"unsigned long __cdecl ThreadRecordMsg（void）"中引用（？ThreadRecordMsg @@ YAKXZ）的
Smsreceiver2Dlg.obj的 Smsreceiver2
推荐答案
包括一个标题只是定义了一些符号;为了让链接器解析这些符号，你必须链接到实现它们的库，在你的情况下，它是sms.lib
Including a header simply defines some symbols; in order for the linker to resolve such symbols you have to link to the library which implements them which, in your case, is sms.lib
