sendmessage怎么在易语言中让它找到指定窗口然后发送按键消息而且支持后台的哦谢谢大家帮忙解决解决吧！

       发送按键消息用这个命令：ndmessage(你要接收消息的监控主力源码指标窗口句柄,自定义消息,0,0)

       而支持后台的话，你用了时钟去循环执行，就已经可以后台了。正版游戏源码

       关键在于找到指定的新闻Android源码窗口，一般窗口所属进程的名称是不变的，那就可以从进程名取出窗口句柄，然后就sendmessage就行了。

       值得一提的是这个方法用来对付网络游戏不一定管用，网络游戏开发者有一定的防范措施的！

       你可以用来对付系统记事本测试一下程序是否有效

android的Handler中sendEmptyMessage与sendMessage的区别？

       çœ‹æºç  根据参数的不同互相调用 public final boolean sendMessage(Message msg) { return sendMessageDelayed(msg, 0); } /** * Sends a Message containing only the what value. * * @return Returns true if the message was successfully placed in to the * message queue. Returns false on failure, usually because the * looper processing the message queue is exiting. */ public final boolean sendEmptyMessage(int what) { return sendEmptyMessageDelayed(what, 0); }

为什么用::SendMessage(m_hWnd, BM_GETSTATE, 0, 0)这个函数将如何完成它的功能的？

       sendmessage,是发一个消息到MFC的消息循环里.然后就会被执行了.

       OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)重载这个就可以自己响应你发的消息了.

       MFC 里面都是用消息实现的.

       sendmessage也是有返回值的..你可以自己处理这些返回.

       --------------------

       BM_GETSTATE

       这些都是被封装了的...没公开..

       就算OnCmdMsg..也只是在半路给我们踩一脚而已,底层不会公开的.

VB Instr

       çœ‹äº†ä½ çš„问题，按照你的思路使用sendmessage函数进行粘贴，我做了以下分析。

       ä¸€ã€é¦–先实现将类似“/F”的文字替换为其它文字，如替换成“(插入图片)”，以下的代码就可以实现

       Private Declare Function sendmessage Lib "user" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

       Private Const WM_PASTE = &H

       Private Sub Command1_Click()

        Dim Pos As Integer

        Pos = InStr(1, RichTextBox1.Text, "/F", vbTextCompare)

        Do Until Pos = 0

        Me.RichTextBox1.SelStart = Pos - 1

        Me.RichTextBox1.SelLength = 4

        Clipboard.Clear

        Clipboard.SetText "(插入图片)"

        sendmessage Me.RichTextBox1.hwnd, WM_PASTE, ByVal 0&, ByVal 0&

        Pos = InStr(1, RichTextBox1.Text, "/F", vbTextCompare)

        Loop

       End Sub

       äºŒã€ä½¿ç”¨åŒä¸Šçš„方法替换图片，发现可以显示图片，但图片位置不对，代码如下

       Private Declare Function sendmessage Lib "user" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

       Private Const WM_PASTE = &H

       Private Sub Command1_Click()

        Dim Pos As Integer

        Pos = InStr(1, RichTextBox1.Text, "/F", vbTextCompare)

        Do Until Pos = 0

        Me.RichTextBox1.SelStart = Pos - 1

        Me.RichTextBox1.SelLength = 4

        Clipboard.Clear

        Clipboard.SetData LoadPicture(App.Path & "\help.gif")

        sendmessage Me.RichTextBox1.hwnd, WM_PASTE, ByVal 0&, ByVal 0&

        Pos = InStr(1, RichTextBox1.Text, "/F", vbTextCompare)

        Loop

       End Sub

       ä¸‰ã€å¦‚果将RichTextBox1中的文字全部写成半角英文，如：

       AAAAAAAA/FBBBBBBBBBB/FCCCCCCCC/FDDDDDD/FEEEE

       å‘现图片的位置全部都对了，但如果写成全角的英文，发现图片的位置又不对了

       ç»¼åˆä»¥ä¸Šä¸‰ç‚¹ï¼Œå¯ä»¥çœ‹å‡ºsendmessage函数可能存在bug，当它粘贴文字时，完全没问题，而粘贴图片时，却同其它文字的字节数或者是ascii码有关，我测试了多种方法，均无法消除sendmessage的bug

vb问题：希望可以给代码

       先新建一个模块，里面添加API声明

       Option Explicit

       Declare Function MoveWindow Lib "user" (ByVal hwnd As Long,课堂视频源码 ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal bRepaint As Long) As Long

       Declare Function SendMessage Lib "user" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

       Public Const LB_INITSTORAGE = &H1A8

       Public Const LB_ADDSTRING = &H

       Public Const WM_SETREDRAW = &HB

       Public Const WM_VSCROLL = &H

       Public Const SB_BOTTOM = 7

       Declare Function GetLogicalDrives Lib "kernel" () As Long

       Declare Function FindFirstFile Lib "kernel" Alias "FindFirstFileA" (ByVal lpFileName As String, lpFindFileData As WIN_FIND_DATA) As Long

       Public Const INVALID_HANDLE_VALUE = -1

       Declare Function FindNextFile Lib "kernel" Alias "FindNextFileA" (ByVal hFindFile As Long, lpFindFileData As WIN_FIND_DATA) As Long

       Declare Function FindClose Lib "kernel" (ByVal hFindFile As Long) As Long

       Type FILETIME

       dwLowDateTime As Long

       然后在窗体上制作2个菜单，放置一个ListBox和一个PictureBox

       程序运行时就能够通过输入文件名而进行模糊查找了
