VC从文件全路径中获取文件名和扩展名方法

方法一：
CString CPrintImage::GetFileTitleFromFileName(CString FileName,CString& ExtendName) //获取文件名和扩展名
{
    int Where;
    Where=FileName.ReverseFind('//');
    if(Where==-1)
    {
        Where=FileName.ReverseFind('/');
    }
    CString FileTitle=FileName.Right(FileName.GetLength()-1-Where);
    int Which=FileTitle.ReverseFind('.');
    ExtendName=FileTitle.Right(FileTitle.GetLength()-Which-1);
    if (Which!=-1)
    {
        FileTitle=FileTitle.Left(Which);
    }
    return FileTitle;
}
调用方法：
CString a,b,c;
a="c://kele8//shootman2//vision//123.exe";
b=this->GetFileTitleFromFileName(a,c);
AfxMessageBox(b);    //弹出123.exe
AfxMessageBox(c);    //弹出exe

方法二：
CString CPrintImage::GetFileTitleFromFileName(CString FileName, BOOL Ext)   
{   
    int Where;   
    Where = FileName.ReverseFind('//');  
    if (Where == -1)  
        Where = FileName.ReverseFind('/');  
    CString FileTitle = FileName.Right(FileName.GetLength() - 1 - Where);  
    if (!Ext)  
    {  
        int Which = FileTitle.ReverseFind('.');   
        if (Which != -1)   
            FileTitle = FileTitle.Left(Which);   
    }   
    return FileTitle;   
}  
调用方法：
CString a,b,c;
a="c://kele8//shootman2//vision//123.exe";
b=this->GetFileTitleFromFileName(a,TRUE);
c=this->GetFileTitleFromFileName(a,FALSE);
AfxMessageBox(b);   弹出123.exe
AfxMessageBox(c);   弹出123
