如何用VB.NET把执行文件加到窗体中加以一个panel用来显示应用程序的,就是放你那个easycap的 , 代码如下
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内
SendMessage(h, WM_SYSCOMMAND, SC_MAXIMIZE, 0)
End Sub
把其中的c:\windows\system32\cmd.exe换成你要嵌入的应用程序
.net程序无法加载dll文件,找不到指定的模块 。是在重装系统和VS软件之后出现的1、文件没有vb.net加载文件了vb.net加载文件 , 通常是程序用vb.net加载文件了非window或者.net自带的dll,从别的地方找的第三方的 。按照vb.net加载文件你说的你重装系统和VS软件,那么有可能是之前找的第三方的dll然后放到了C盘什么的 。
2、dll本身出问题了 , 不是所有的dll都能被VB或者C#识别的,你用C和C写的就不能直接使用 。
