Vc++ 控件用法总结之List Control

1.新建对话框MFC,在对话框上放一个ListCtrl

ID:IDC_PATH

View:Report

2.为ListCtrl添加变量

右击->添加变量m_wndPath

3.找到OnInitDialog()函数添加如下代码：

// TODO: 在此添加额外的初始化代码

m_wndPath.DeleteAllItems();//清空
m_wndPath.InsertColumn(0,_T("项目"));//添加列
m_wndPath.InsertColumn(1,_T("所在路径"));
m_wndPath.SetColumnWidth(0, 150);//设置列宽
m_wndPath.SetColumnWidth(1, 350);
m_wndPath.SetRedraw(FALSE);//防止重绘

int nIndex;
//char|TCHAR项目属性->字符集：使用多字节字符集
TCHAR Path[MAX_PATH+1];//TCHAR取代char  MAX_PATH最长路径
nIndex=m_wndPath.InsertItem( 0,_T("Windows目录") );
if( nIndex < 0 ) return TRUE;
GetWindowsDirectory(Path,MAX_PATH);//取得windows目录
m_wndPath.SetItemText( nIndex, 1, Path );

LPITEMIDLIST pidl;//桌面CSIDL_DESKTOPDIRECTORY
//用来得到系统的某些特定文件夹的位置信息
if(SUCCEEDED(SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOPDIRECTORY,&pidl)))
{
    if(SHGetPathFromIDList(pidl, Path))//功能是把项目标志符列表转换为文档系统路径
    {
        nIndex=m_wndPath.InsertItem( 0,_T("桌面"));//成功则返回0
        if( nIndex < 0 )
        {
            return TRUE;
        }
        m_wndPath.SetItemText( nIndex, 1, Path );
    }
}

m_wndPath.SetRedraw(TRUE);//显示

return TRUE;  // 除非将焦点设置到控件，否则返回 TRUE

4.char被TCHAR取代，若要用则：

项目属性->字符集：使用多字节字符集

参考代码：

m_wndPath.DeleteAllItems();
m_wndPath.InsertColumn(0,"项目");
m_wndPath.InsertColumn(1,"所在路径");
m_wndPath.SetColumnWidth(0, 150);
m_wndPath.SetColumnWidth(1, 350);
m_wndPath.SetRedraw(FALSE);

int nIndex;
const int nFolder[]={ CSIDL_ALTSTARTUP,CSIDL_APPDATA,CSIDL_BITBUCKET,CSIDL_COMMON_ALTSTARTUP,

char Path[MAX_PATH+1];
nIndex=m_wndPath.InsertItem( 0,"Windows目录" );
if( nIndex < 0 ) return TRUE;
GetWindowsDirectory(Path,MAX_PATH);
m_wndPath.SetItemText( nIndex, 1, Path );

nIndex=m_wndPath.InsertItem( 0,"System目录" );
if( nIndex < 0 ) return TRUE;
GetSystemDirectory(Path,MAX_PATH);
m_wndPath.SetItemText( nIndex, 1, Path );

int i,count=sizeof(nFolder)/sizeof(int);
for(i=0;i<count;i++)
{
    LPITEMIDLIST pidl;
    LPMALLOC pShellMalloc;

    if(SUCCEEDED(SHGetMalloc(&pShellMalloc)))
    {
        if(SUCCEEDED(SHGetSpecialFolderLocation(NULL,
            nFolder[i],&pidl)))
        {
            if(SHGetPathFromIDList(pidl, Path))
            {
                nIndex=m_wndPath.InsertItem( 0,strFolderName[i] );
                if( nIndex < 0 )
                {
                    pShellMalloc->Free(pidl);
                    pShellMalloc->Release();
                    return TRUE;
                }
                m_wndPath.SetItemText( nIndex, 1, Path );
            }
            pShellMalloc->Free(pidl);
        }
        pShellMalloc->Release();
    }
}
m_wndPath.SetRedraw(TRUE);
