使用NetScheduleJobEnum取得AT职位

问题描述

你好，

我想获取所有AT计划任务的应用程序名称的列表.
我正在使用NetScheduleJobEnum()和一个AT_ENUM结构数组.但是在我的代码中，运行NetScheduleJobEnum后，buffPtr并不指向AT_ENUM，并且该行:
for(ai = buffPtr, cnt = 0; cnt < nrRead; cnt++, ++buffPtr)

甚至没有运行一次.我正在附上我的代码.
问题是什么?
谢谢

Hello,

I want to get a list of all the AT scheduled tasks'' application names.
I''m using NetScheduleJobEnum() and an array of AT_ENUM structs. But in my code, after running of NetScheduleJobEnum, buffPtr doesn''t point to an AT_ENUM, and the line:
for(ai = buffPtr, cnt = 0; cnt < nrRead; cnt++, ++buffPtr)

doesn''t run even one time. I''m attaching my code.
What is the problem?
Thanks

DWORD res;
DWORD id;
DWORD maxid;
AT_ENUM* buffPtr = NULL;
AT_ENUM* ai;
DWORD nrRead;
DWORD posRead;
DWORD resumHandle;
DWORD cnt;
CString str;
ITaskScheduler *pITS;

hr = CoInitialize(NULL);

hr = CoCreateInstance(CLSID_CTaskScheduler,
                  NULL,
                  CLSCTX_INPROC_SERVER,
                  IID_ITaskScheduler,
                  (void **) &pITS);


res = ::NetScheduleJobEnum(NULL,
    (LPBYTE*)&buffPtr,
    MAX_PREFERRED_LENGTH,
    &nrRead,
    &posRead,
    &resumHandle);


if(res != 0)
{
    int i;
}
else

    for(ai = buffPtr, cnt = 0; cnt < nrRead; cnt++, ++buffPtr)
    {
        str.Format("Jobid: %d Command: %s", ai->JobId, ai->Command);
        ::AfxMessageBox(str);
    }

    if(buffPtr != NULL)
    {
        NetApiBufferFree(buffPtr);
    }
}

推荐答案

res = ::NetScheduleJobEnum(NULL,
    (LPBYTE*)&buffPtr,
    MAX_PREFERRED_LENGTH,
    &nrRead,
    &posRead,
    NULL);


if(res != 0)
{
    int i;
}
else

    for(ai = buffPtr, cnt = 0; cnt < nrRead; cnt++, ++buffPtr)
    {
        str.Format(L"Jobid: %d Command: %s", ai->JobId, ai->Command);
        ::AfxMessageBox(str);
    }

    if(buffPtr != NULL)
    {
        NetApiBufferFree(buffPtr);
    }

{
NetApiBufferFree(buffPtr);
}
ULL)
{
NetApiBufferFree(buffPtr);
}

ULL)
{
NetApiBufferFree(buffPtr);
}
ULL)
{
NetApiBufferFree(buffPtr);
}
