VB6中如何獲取磁盤信息？

樓上的朋友可能有點(diǎn)小小的誤會(huì)樓主的意思了，

樓主朋友可能要現(xiàn)在已經(jīng)分好區(qū)的空間大小，已用空間、剩余空間。

當(dāng)然我也不敢保證誰對誰錯(cuò)，

我還是把我的理解 然后 也把代碼貼出來讓樓主看看吧

下面代碼的功能：顯示光驅(qū)當(dāng)前分區(qū)，以及各個(gè)盤的總空間，剩余空間。

當(dāng)然。如果要硬盤總空間，我們可以把所有空間加起來，就達(dá)到要求了。

希望下面的代碼對樓主有用！

'硬盤空間大小 以及光驅(qū)

vb.net 磁盤文件列表，界面如圖，在.net下如何實(shí)現(xiàn)？

預(yù)先準(zhǔn)備三個(gè)圖標(biāo)文件，用于樹型控件中顯示磁盤符號和文件夾的圖像之用。

1、窗體上添加控件如下：

組合框控件 ComboBox1，樹型控件 TreeView1，列表框控件 ListBox1，圖像列表控件 ImageList1。

選中TreeView1，設(shè)置其ImageList屬性為ImageList1。

2、設(shè)置屬性

選中圖像列表控件 ImageList1，在屬性窗口里，選中屬性Images，單擊三個(gè)小點(diǎn)按鈕，出現(xiàn)圖像集合編輯器窗口，單擊[添加按鈕]，一一把準(zhǔn)備好的圖標(biāo)文件進(jìn)行添加，注意先后次序，如果不符合要求可以通過上下移動(dòng)按鈕重新改變次序。完成后單擊[確定]。

運(yùn)行圖如下：
