如何从Windows窗体应用程序中打开记事本，并把一些文本的呢？ [英] How to open Notepad from a Windows Forms application and place some text in it?

问题描述

我是新来的编程和Windows窗体开发。我使用VB.NET和Visual Studio 2008。

我的问题是：如何打开从Windows窗体应用程序记事本，然后将一些文本字符串中的记事本窗口

解决方案

1. 使用的Process.Start 的属性的ShellExecute 设置为真;
2. 使用剪贴板：<一href="http://www.dreamin$c$c.net/forums/topic/40011-how-do-i-put-text-in-another-program/">http://www.dreamin$c$c.net/forums/topic/40011-how-do-i-put-text-in-another-program/

更新

的Process.Start 返回进程对象，它有一个 MainWindowHandle 属性。在上面提到的链接发送文本代替的FindWindow时使用该句柄。

更新2

有些code

 常量WM_SETTEXT作为整数=安培; HC
＆LT;的DllImport（user32.dll中）＆GT; _
私人共享SendMessage函数（HWND作为IntPtr的，消息作为整数，wParam中的IntPtr，＆LT;的MarshalAs（UnmanagedType.LPStr）＆GT; lParam的作为字符串）作为IntPtr的
端功能

私人共享的Sub Main（）
    的ProcessStartInfo用于指示Process类
    就如何启动一个新的进程。该UseShellExecute告诉
    这个过程的类，它（其中包括）应搜索应用
    使用PATH环境变量。
    昏暗的PIS作为的ProcessStartInfo =新的ProcessStartInfo（NOTEPAD.EXE）
    pis.UseShellExecute = TRUE

    这个过程类用于启动进程
    '它返回一个对象，它可用于控制启动的过程
    昏暗的记事本作为流程=的Process.Start（PIS）

    SendMessage函数是用来发送剪贴板消息，记事本的
    主窗口。
    昏暗textToAdd作为字符串=文本中添加
    SendMessage函数（notepad.MainWindowHandle，WM_SETTEXT，IntPtr.Zero，textToAdd）
结束小组
 

I'm new to programming and to Windows Forms development. I'm using VB.NET and Visual Studio 2008.

My question is: How do I open Notepad from a Windows Forms application, and then place some text string in the Notepad window?

解决方案

1. Use Process.Start with the property ShellExecute set to true;
2. Use the clipboard: http://www.dreamincode.net/forums/topic/40011-how-do-i-put-text-in-another-program/

Update

Process.Start returns a Process object which has a MainWindowHandle property. Use that handle when sending text instead of the FindWindow in the above mentioned link.

Update 2

Some code

Const WM_SETTEXT As Integer = &HC
<DllImport("user32.dll")> _
Private Shared Function SendMessage(hWnd As IntPtr, Msg As Integer, wParam As IntPtr, <MarshalAs(UnmanagedType.LPStr)> lParam As String) As IntPtr
End Function

Private Shared Sub Main()
    'ProcessStartInfo is used to instruct the Process class
    ' on how to start a new process. The UseShellExecute tells
    ' the process class that it (amongst other) should search for the application
    ' using the PATH environment variable.
    Dim pis As ProcessStartInfo = New ProcessStartInfo("notepad.exe")
    pis.UseShellExecute = True

    ' The process class is used to start the process
    ' it returns an object which can be used to control the started process
    Dim notepad As Process = Process.Start(pis)

    ' SendMessage is used to send the clipboard message to notepad's
    ' main window.
    Dim textToAdd As String = "Text to add"
    SendMessage(notepad.MainWindowHandle, WM_SETTEXT, IntPtr.Zero, textToAdd)
End Sub
