Winforms 错误LNK 2028和2001

我正在从事一个在Visual C++2010中使用Windows窗体的项目。我正在使用这个类。以下是相关代码：

我包括头文件：

#include "BasicExcel.hpp"
using namespace YExcel;

然后，当我按下按钮时，软件会在单元格1,4处写入“Test str1”：

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
         //Code for Writing to Excel
            BasicExcel x;
        // Load a workbook with one sheet, write some test data at (1,4)
            x.Load("TestFile.xlsx");
            BasicExcelWorksheet* sheet = x.GetWorksheet("Sheet1");
            BasicExcelCell* cell;
            sheet->Cell(1,4)->SetString("Test str1");
     }

执行此操作时，会出现以下错误：

我已经试着把它修好了，但我对链接知之甚少。如果有人能启发我，我将不胜感激。

谢谢

您包含了一个头文件，但您是否向项目中添加了任何潜在的源文件？谢谢！这真的很简单。我本应该能够弄明白这一点，但所有这些链接器错误的解决方案都是非常复杂的帖子，看起来都是针对特定项目的。再次感谢！
