最近开发使用到 libxl，用的是3.8.0 破解版。
具体过程：
1、将lib.dll放在exe同目录下，在代码中引用 libxl.lib
#pragma comment(lib, ".\\Lib\\libxl.lib")
2、包含头文件 libxl.h
3、实例
//m_strFilePath为excel文件的完整路径
CString ext = ::PathFindExtension(m_strFilePath);
if(ext.CompareNoCase(L".xlsx") == 0)
book = xlCreateXMLBook(); //针对.xlsx
else
book = xlCreateBook(); //针对.xls if(!book)
{
return;
} const wchar_t * x = L"Halil Kural";
const wchar_t * y = L"windows-2723210a07c4e90162b26966a8jcdboe";
book->setKey(x, y); //设置key，即破解^_^ if(!book->load(m_strFilePath))
{
return;
} int sheetCount = book->sheetCount(); //工作表总数量
for (int index = 0; index < sheetCount; ++index)
{
Sheet *sheet =book->getSheet(index++);
if(!sheet)
continue;
int firstRow = sheet->firstRow(); //有数据的第一行行号
int lastRow = sheet->lastRow(); //有数据的最后一行行号
int firstCol = sheet->firstCol(); //有数据的第一列列号
int lastCol = sheet->lastCol(); //有数据的最后一列列号 //找出表头（测试数据）
map<int,wstring> mapColNames;
for(int c = firstCol; c < lastCol; ++c)
{
const wchar_t* str = sheet->readStr(firstRow, c);
if(!str)
continue;
mapColNames[c] = str;
} //确定每个表头代表的意义（测试数据）
map<int,eFIELD> mapColTypes;
for (auto it = mapColNames.begin(); it != mapColNames.end(); ++it)
{
eFIELD e = GetFieldTypeByName(it->second.c_str());
mapColTypes[it->first] = e;
} //逐行读取数据
for (int row = firstRow+1; row < lastRow; ++row)
{
for(int c = firstCol; c < lastCol; ++c)
{
CString strValue;
CellType t = sheet->cellType(row, c);
if(t == CELLTYPE_NUMBER)
{
double db = sheet->readNum(row, c);//test
LONG64 number = (LONG64)db;
if(number > 0)
strValue.Format(L"%I64d", number);
}
else
const wchar_t* s = sheet->readStr(row, c); //读取内容
}
}
}
4、读取时间格式的数据
CString strValue;
bool bDate = sheet->isDate(row, col);
if (bDate)
{
double db = sheet->readNum(row, col);
int year=, month=, day=;
bool b = book->dateUnpack(db, &year, &month, &day); //将读取的时间 转换为时间戳
unsigned __int64 ftNow;
SYSTEMTIME time;
ZeroMemory(&time, sizeof(SYSTEMTIME)),
time.wYear = year;
time.wMonth = month;
time.wDay = day;
SystemTimeToFileTime(&time,(LPFILETIME)&ftNow);
__int64 timeStamp = (__int64)((ftNow-0x019db1ded53e8000)/);//毫秒
strValue.Format(L"%I64d", timeStamp);
}
