vb中怎麼把文件夾設(shè)為共享

NET SHARE命令設(shè)置共享路徑,如將D盤設(shè)為共享

創(chuàng)新互聯(lián)從2013年成立，先為儋州等服務(wù)建站，儋州等地企業(yè)，進(jìn)行企業(yè)商務(wù)咨詢服務(wù)。為儋州企業(yè)網(wǎng)站制作PC+手機(jī)+微官網(wǎng)三網(wǎng)同步一站式服務(wù)解決您的所有建站問(wèn)題。

所以你可以使用shell "net share D$"

Vb.net 請(qǐng)問(wèn)如何快速時(shí)時(shí)讀取共享文件夾資料

File.WriteAllText("\\10.1.37.222\shared\temp.txt", "");

如果能生成就沒(méi)問(wèn)題。

如果不用net use的方法，vb.net 有辦法訪問(wèn)共享文件或者共享文件夾嗎

我不會(huì)VB，但是都是.net。c#的代碼稍微轉(zhuǎn)換一下就可以了。

C#實(shí)現(xiàn)訪問(wèn)網(wǎng)絡(luò)共享文件夾，使用?WNetAddConnection2A?和?WNetCancelConnection2A。

在目標(biāo)服務(wù)器建立共享文件夾，建立訪問(wèn)賬號(hào)test;

vb.net?怎么實(shí)現(xiàn)多個(gè)控件共同使用一個(gè)變量

把變量定義時(shí)增加Shared關(guān)鍵字即可.如:

Private

Shared

AAA

As

String

Public

Shared

AAA

As

String

......

這樣AAA在一個(gè)應(yīng)用程序里就是公用的.

------------------------------------------------------

補(bǔ)充:

不可能沒(méi)用,我都是這樣做的.

該控件使用中,自己看吧:

Public

Class

CMB_MemoryTextBox

Inherits

TextBox

#Region

"

變量定義

"

Private

Shared

p_HisData

As

STRU_DATA

'用數(shù)據(jù)表保存所有控件的歷史記錄

Private

Shared

p_FileName

As

String

'保存歷史記錄的文件名

......

vb.net里面老是看到什么“共享方法”“共享屬性”是什么意思？

可以直接從類調(diào)用共享方法，而不必首先創(chuàng)建該類的實(shí)例。共享屬性與之類似，可以在一創(chuàng)建類實(shí)例的情況下訪問(wèn)，并且即使有了多個(gè)實(shí)例，共享屬性仍然只有一個(gè)，就是說(shuō)，設(shè)置了該屬性后，對(duì)所有實(shí)例有效。類似于全局變量。

使用vb.net將以太網(wǎng)共享給虛擬wifi網(wǎng)絡(luò)

最簡(jiǎn)單的辦法是用句柄操作窗體，這種方法就好比是計(jì)算機(jī)在代替你在打開(kāi)設(shè)置窗口，完成設(shè)置。

比較難實(shí)現(xiàn)的方法是用API，不過(guò)我不知道用那些API，而且還要驅(qū)動(dòng)支持

因?yàn)関b。net是高級(jí)語(yǔ)言，不能直接操作驅(qū)動(dòng)，所以直接寫(xiě)匯編是不可行的
