对话框实现文件拖拽

话不多说，直接上代码:

void C目录选择对话框Dlg::OnDropFiles(HDROP hDropInfo)
{
    TCHAR szPath[MAX_PATH] = { 0 };
    UINT nCount =  DragQueryFile(hDropInfo, 0xFFFFFFFF, NULL, 0);
    for (size_t i = 0; i < nCount; i++)
    {
        DragQueryFile(hDropInfo, i, szPath, MAX_PATH);
        MessageBox(szPath);
    }
    DragFinish(hDropInfo);
    CDialogEx::OnDropFiles(hDropInfo);
}
