VC++使用GridCtrl link出错
在头文件中加入了
#include "Grid\GridCtrl.h"
...
CGridCtrl m_Grid;
然后在DoDataExchange中使用
void CCustomcontrol::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CCustomcontrol)
// NOTE: the ClassWizard will add DDX and DDV calls here
//}}AFX_DATA_MAP
DDX_GridControl(pDX, IDC_SHEET, m_Grid);


}
编译能通过，为什么link的时候会报错啊
Linking...
