如何在C#/ Win32中编写和发送文本到mIRC？

Question

在上一个问题中,我询问了如何将文本发送到记事本.它帮了我很大的忙.对于第2部分,这是相同应用的mIRC的简化版本:

[DllImport("User32.dll", EntryPoint = "FindWindow")]
public static extern IntPtr FindWindow(String lpClassName, String lpWindowName);
[DllImport("user32.dll", EntryPoint = "FindWindowEx")]
public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);
[DllImport("User32.dll")]
public static extern int SendMessage(IntPtr hWnd, int uMsg, int wParam, string lParam);

IntPtr mainHandle = FindWindow("mIRC", null);
IntPtr serverHandle = FindWindowEx(mainHandle, new IntPtr(0), "MDIClient", null);
IntPtr chanHandle = FindWindowEx(serverHandle, new IntPtr(0), "mIRC_Channel", null);
IntPtr editHandle = FindWindowEx(chanHandle, new IntPtr(0), "Edit", null);

SendMessage(editHandle, 0x000C, 0, textBox1.Text);

这似乎对我来说是正确的,除了它不起作用!是否窗口名称不正确(MDIClient,mIRC_Channel和Edit)？这些是我通过Google搜索"FindWindowEx mIRC"在网站上找到的值.

1.)我在上面做错了什么？

2.)作为参考,一般来说,有一种简单的方法可以找到所有用于的窗口名称FindWindowEx()？

Answer 1

此代码适用于我（mirc 6.31）：

IntPtr mainHandle = FindWindow("mIRC", null);
IntPtr serverHandle = FindWindowEx(mainHandle, new IntPtr(0), "MDIClient", null);  
IntPtr chanHandle = FindWindowEx(serverHandle, new IntPtr(0), "mIRC_Channel", null);  
IntPtr editHandle = FindWindowEx(chanHandle, new IntPtr(0), "richEdit20A", null);
SendMessage(editHandle, 0x000C, 0, "Hello World");

请注意更改后的窗口类（richedit20A 而不是 edit）。刚刚使用 Spy++ 找到了正确的类。

对于窗口句柄，一种可能是使用EnumWindows或EnumChildWindows API。
