我有一个 C# 问题,
我能够模拟对当前窗口的点击,但如果窗口被最小化或隐藏,我想这样做。
有任何想法吗?
这是一个完整工作的片段,它将为您提供窗口句柄、目标子窗口并将消息发布到该子窗口。
#include "TCHAR.h"
#include "Windows.h"
int _tmain(int argc, _TCHAR* argv[])
{
HWND hwndWindowTarget;
HWND hwndWindowNotepad = FindWindow(NULL, L"Untitled - Notepad");
if (hwndWindowNotepad)
{
// Find the target Edit window within Notepad.
hwndWindowTarget = FindWindowEx(hwndWindowNotepad, NULL, L"Edit", NULL);
if (hwndWindowTarget) {
PostMessage(hwndWindowTarget, WM_CHAR, 'G', 0);
}
}
return 0;
}
目前它会将G
字符发送到记事本“Untitled”(打开一个新记事本,什么也不做。

您可以找到使用Visual Studio 附带的子窗口。
下面是一个使用 SendInput 发送鼠标事件的例子:
#include "TCHAR.h"
#include "Windows.h"
int _tmain(int argc, _TCHAR* argv[])
{
POINT pt;
pt.x = 300;
pt.y = 300;
HWND hwndWindowTarget;
HWND hwndWindowNotepad = FindWindow(NULL, L"Untitled - Notepad");
if (hwndWindowNotepad)
{
// Find the target Edit window within Notepad.
hwndWindowTarget = FindWindowEx(hwndWindowNotepad, NULL, L"Edit", NULL);
if (hwndWindowTarget) {
PostMessage ( hwndWindowTarget, WM_RBUTTONDOWN, 0, (pt.x) & (( pt.y) << 16) );
PostMessage ( hwndWindowTarget, WM_RBUTTONUP, 0, (pt.x ) & (( pt.y) << 16) );
}
}
return 0;
}
抱歉,这花了这么长时间,这是 C# 版本:
using System;
using System.Runtime.InteropServices;
namespace Sandbox
{
class Program
{
[DllImport("user32.dll")]
static extern bool PostMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);
[DllImport("user32.dll")]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll")]
static extern IntPtr FindWindowEx(IntPtr hWnd, string lpClassName, string lpWindowName, string lParam);
public const Int32 WM_CHAR = 0x0102;
public const Int32 WM_KEYDOWN = 0x0100;
public const Int32 WM_KEYUP = 0x0101;
public const Int32 VK_RETURN = 0x0D;
public const string windowName = "Untitled - Notepad";
static void Main(string[] args)
{
Console.WriteLine($"Finding {windowName}");
var hwndWindowNotepad = FindWindow(null, "Untitled - Notepad");
if (hwndWindowNotepad != 0)
{
// Find the target Edit window within Notepad.
var hwndWindowTarget = FindWindowEx(hwndWindowNotepad, null, "Edit", null);
if (hwndWindowTarget != 0)
{
Console.WriteLine($"Sending Char to {windowName}");
PostMessage(hwndWindowTarget, WM_CHAR, 'G', 0);
}
}
}
}
}
