vb.net 調(diào)用C語言可執(zhí)行程序并傳值？
在c語言中每一個變量都有兩個屬性一個是值，一個是址。比如inta=2;變量a的值是2，變量a的地址，可以用取地址
成都創(chuàng)新互聯(lián)服務(wù)項目包括射洪網(wǎng)站建設(shè)、射洪網(wǎng)站制作、射洪網(wǎng)頁制作以及射洪網(wǎng)絡(luò)營銷策劃等。多年來，我們專注于互聯(lián)網(wǎng)行業(yè)，利用自身積累的技術(shù)優(yōu)勢、行業(yè)經(jīng)驗、深度合作伙伴關(guān)系等，向廣大中小型企業(yè)、政府機構(gòu)等提供互聯(lián)網(wǎng)行業(yè)的解決方案，射洪網(wǎng)站推廣取得了明顯的社會效益與經(jīng)濟效益。目前，我們服務(wù)的客戶以成都為中心已經(jīng)輻射到射洪省份的部分城市，未來相信會繼續(xù)擴大服務(wù)區(qū)域并繼續(xù)獲得客戶的支持與信任！
操作符
獲取，即a。因此以C語言的函數(shù)傳遞中具備兩種方式傳遞參數(shù)，一種是傳址，一種傳值。比如voidf1(intv){;}//函數(shù)f1v
VB.NET把dll嵌入到exe內(nèi)部。
我的方案是將相關(guān)dll的放入vb的資源文件中,生成exe,在exe執(zhí)行時先將dll釋放到exe目錄(或path所在目錄),這樣就只有1個exe就可以了
如何用VB.NET把執(zhí)行文件加到窗體中
加以一個panel用來顯示應(yīng)用程序的，就是放你那個easycap的，代碼如下
Declare Function SetParent Lib "user32" Alias "SetParent" (ByVal hWndChild As IntPtr, ByVal hWndNewParent As IntPtr) As Integer
Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Int32, ByVal wMsg As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Int32
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Int32, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Int32) As Int32
Private Const WM_SYSCOMMAND As Int32 = H112
Private Const SC_MAXIMIZE As Int32 = HF030
Private Const SC_MINIMIZE As Int32 = HF020
Private Const SC_RESTORE As Int32 = HF120
Public Const SW_HIDE = 0
Public Const SW_SHOW = 5
Private Declare Function ShowWindow Lib "user32.dll" (ByVal hwnd As Int32, ByVal nCmdShow As Int32) As Int32
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ShellExecute(Me.Panel1.Handle, "open", "c:\windows\system32\cmd.exe", Nothing, ".", SW_HIDE)
System.Threading.Thread.Sleep(50)
Dim h As IntPtr = FindWindow(Nothing, "c:\windows\system32\cmd.exe")
ShowWindow(h, SW_HIDE)
SetParent(h, Me.Panel1.Handle) '嵌到panel1內(nèi)
SendMessage(h, WM_SYSCOMMAND, SC_MAXIMIZE, 0)
End Sub
把其中的c:\windows\system32\cmd.exe換成你要嵌入的應(yīng)用程序
