工作總結2
1..strcpy提供了字符串的複製。即strcpy只用於字符串複製，並且它不僅複製字符串內容之外，還會複製字符串的結束符。
char* strcpy(char* dest, const char* src);
2.獲取本地時間：
GetLocalTime(&InsertSysTime);//獲取本地時間
3.十6進制轉為10進制地址
sscanf(strAddr.Left(strAddr.Find(‘H’)>0?strAddr.Find(‘H’):strAddr.Find(‘h’)),
“%X”, &m_nDeviceAddress)
4.年月日時分秒
function getDateStr(seconds){
var date = new Date(seconds*1000)
var year = date.getFullYear();
var month = date.getMonth() + 1;
var day = date.getDate();
var hour = date.getHours() < 10 ? “0” + date.getHours() : date.getHours();
var minute = date.getMinutes() < 10 ? “0” + date.getMinutes() : date.getMinutes();
var second = date.getSeconds() < 10 ? “0” + date.getSeconds() : date.getSeconds();
var currentTime = year + “-” + month + “-” + day + ” ” + hour + “:” + minute + “:” + second;
return currentTime
}
//getDateStr(1524637692)>”2018-4-25 14:28:12″
//C++
SYSTEMTIME sys = {0};
sys = Time(lpszResp,nHead,n);
CTime cTime(sys);
time_t t = cTime.GetTime();
SYSTEMTIME CMyDevice::Time(LPCTSTR lpszResp,int nHead,int m)
{
/*double dbDaTa = 0;*/
//double myshort = 0;
SYSTEMTIME sys;
memset(&sys,0,sizeof(SYSTEMTIME));
int nData = 0;
CString strData = _T(“”);
char chData1[1] = {0};
char chData2[2] = {0};
char chData3[3] = {0};
char chData4[4] = {0};
char chData5[5] = {0};
char chData6[6] = {0};
char chDATA1 =(char)lpszResp[nHead + 19 + 36*m];
char chDATA2 =(char)lpszResp[nHead + 20 + 36*m];
char chDATA3 =(char)lpszResp[nHead + 21 + 36*m] ;
char chDATA4 =(char)lpszResp[nHead + 22 + 36*m];
char chDATA5 =(char)lpszResp[nHead + 23 + 36*m];
char chDATA6 =(char)lpszResp[nHead + 24 + 36*m];
/*strData = */
/*sscanf(chData,”%d”,&nData);*/
sprintf(chData1,”%x”,chDATA1);
sprintf(chData2,”%x”,chDATA2);
sprintf(chData3,”%x”,chDATA3);
sprintf(chData4,”%x”,chDATA4);
sprintf(chData5,”%x”,chDATA5);
sprintf(chData6,”%x”,chDATA6);
int nTime1 = atoi(chData1);
int nTime2 = atoi(chData2);
int nTime3 = atoi(chData3);
int nTime4 = atoi(chData4);
int nTime5 = atoi(chData5);
int nTime6 = atoi(chData6);
sys.wYear = 2000 + nTime1;
sys.wMonth = nTime2 ;
sys.wDay = nTime3;
sys.wHour = nTime4;
sys.wMinute = nTime5;
sys.wSecond = nTime6;
return sys;
}
5.選擇文件
原型為
CFileDialog(BOOL bOpenFileDialog, // TRUE for FileOpen, FALSE for FileSaveAs
LPCTSTR lpszDefExt = NULL,
LPCTSTR lpszFileName = NULL,
DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
LPCTSTR lpszFilter = NULL,
CWnd* pParentWnd = NULL);
調用：
CFileDialog dlg(true,NULL,NULL,NULL,”所有文件|*.*”,NULL);
//char szFilter] = {“All Files(*.*)|*.*||”};
//CFileDialog dlg(TRUE,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,szFilter,NULL);
if(IDOK == dlg.DoModal())
{
MessageBox(dlg.GetPathName(),_T(“”));
//m_strXML = dlg.GetPathName();
}
6. CString strAddress = _T(“”);//實現把十進制數轉為16進制數，並且逆序排列
UINT unAddress = atoi(intoData);
sprintf(strAddress.GetBuffer(0), “%0x”, unAddress);
strAddress.ReleaseBuffer();
CString strAddress1 = _T(“”);
CString strAddress2 = _T(“”);
CString strAddress3 = _T(“”);
strAddress1 = strAddress.Right(2);
strAddress = strAddress.Left(strAddress.GetLength()-2);
strAddress2 = strAddress.Right(2);
strAddress3 = strAddress.Left(strAddress.GetLength()-2);
7.sscanf（）的使用
strTime = strAddress.Left(2);//按十六進制轉換
strAddress = strAddress.Mid(2);
int nData = 0;
sscanf(strTime,”%X”,&nData);
strTime = strAddress.Left(1);//按字符串轉換
strAddress = strAddress.Mid(1);
int nData = 0;
sscanf(strTime,”%s”,&nData);
8.由16進制轉為float類型
float freq;
char recv[4] = {0x41, 0xbc, 0x00, 0x00}; //接收到的數據，高位元組到低位元組排列
char * Modbus_HoldReg[4]; //定義保持寄存器指針數組
//第一步：指針初始化
Modbus_HoldReg0] = ((char*)(&freq))+3; //低地址指向高位
Modbus_HoldReg1] = ((char*)(&freq))+2;
Modbus_HoldReg2] = ((char*)(&freq))+1;
Modbus_HoldReg3] = ((char*)(&freq))+0; //高地址指向低位
//第二步：給地址指定的內存單元賦值（對應Modbus協議中的數據解析）
*Modbus_HoldReg0] = recv[0];
*Modbus_HoldReg1] = recv[1];
*Modbus_HoldReg2] = recv[2];
*Modbus_HoldReg3] = recv[3];
printf(“%f\r\n”, freq);
9.字符轉換

CString csMsg1 = _T(“”);
CString csMsg2 = _T(“”);
CString csTest = _T(“測試字符串編碼”);
value.bstrVal = csTest.AllocSysString();
