Question

这个程序怎么改？总是出现错误error C2601:“CBMPtoAVIDlg::choisebmppath”: 本地函数定义是非法的

HCURSOR CBMPtoAVIDlg::OnQueryDragIcon()
{
return static_cast<HCURSOR>(m_hIcon);
char* CBMPtoAVIDlg::choisebmppath(HWND hWnd,CHAR *szTitle, CHAR *szPath)//获得文件夹
{
BROWSEINFO bi;
LPCITEMIDLIST pItemIDList;
bi.hwndOwner = AfxGetMainWnd()->GetSafeHwnd();
bi.pidlRoot = NULL;
bi.pszDisplayName = szPath;
bi.lpszTitle = szTitle;
bi.ulFlags = BIF_RETURNONLYFSDIRS;
bi.lpfn = NULL;
bi.iImage = 0;
pItemIDList = SHBrowseForFolder(&bi);
if(NULL == SHGetPathFromIDList(pItemIDList, szPath) )
{
AfxMessageBox("路径为获取");
}
return (char*)szPath;
}
}

Answer 1

应该要定义一个对象去使用这个函数吧，或者获得当前工程的CBMPtoAVIDlg已经指出的对象。

Answer 2

改成这样就OK啦：
HCURSOR CBMPtoAVIDlg::OnQueryDragIcon()
{
return static_cast<HCURSOR>(m_hIcon);
}
char* CBMPtoAVIDlg::choisebmppath(HWND hWnd,CHAR *szTitle, CHAR *szPath)//获文件夹
{
BROWSEINFO bi;
LPCITEMIDLIST pItemIDList;
bi.hwndOwner = AfxGetMainWnd()->GetSafeHwnd();
bi.pidlRoot = NULL;
bi.pszDisplayName = szPath;
bi.lpszTitle = szTitle;
bi.ulFlags = BIF_RETURNONLYFSDIRS;
bi.lpfn = NULL;
bi.iImage = 0;
pItemIDList = SHBrowseForFolder(&bi);
if(NULL == SHGetPathFromIDList(pItemIDList, szPath) )
{
AfxMessageBox("路径获取");
}
return (char*)szPath;
}
