Question

用CFile类如何实现想文件写入数据？

Answer 1

CFile file;
CString sPath = "....";// 设置文件路径
if (!file.Open(sPath, CFile::modeCreate | CFile::modeWrite))
return;
BYTE* pData; /闹消/ 将数据保存到指针中；
long lsize= 0; /搜亏/ 设置数据液漏知大小
file.Write(pData, lSize);
file.Close();

Answer 2

typedef int (WINAPI ICEPUB_WRITETEXTTOFILE)(char *strText,char *strFilename,int traceFlag);
ICEPUB_WRITETEXTTOFILE *icePub_writeTextToFile = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_writeTextToFile = (ICEPUB_WRITETEXTTOFILE *)GetProcAddress(hDLLDrv, "icePub_writeTextToFile");
}

if(icePub_writeTextToFile != NULL)
{
icePub_writeTextToFile("上火了！","D:\桥樱\program files\\test\\a.txt",1);
}

if(hDLLDrv)
FreeLibrary(hDLLDrv);

typedef int (WINAPI ICEPUB_APPENDTEXTTOFILE)(char *strText,char *strFilename,int traceFlag);
ICEPUB_APPENDTEXTTOFILE *icePub_appendTextToFile = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_appendTextToFile = (ICEPUB_APPENDTEXTTOFILE *)GetProcAddress(hDLLDrv, "icePub_appendTextToFile");
}

if(icePub_appendTextToFile != NULL)
{
icePub_appendTextToFile("头晕、眼花、走路打晃晃！","D:\漏型\program files\敏搜丛\test\\c.txt",1);
}

if(hDLLDrv)
FreeLibrary(hDLLDrv);
