我正在使用以下 SendMessage 函数将文本发送/粘贴到不同的应用程序。但是在那个函数中,我必须从另一个应用程序中给出窗口的名称。
如何更改它以获取当前活动窗口并将代码粘贴到那里?
代码:
[DllImport("user32.dll")]
public static extern int SendMessage(int hWnd, int msg, int wParam, [MarshalAs(UnmanagedType.LPStr)] string lParam);
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);
public const int WM_PASTE = 0x0302;
IntPtr windowHandle = FindWindow("NOTEPAD", null);
IntPtr editHandle = FindWindowEx(windowHandle, IntPtr.Zero, "EDIT", null);
string textToSendToFile = "Input here your text";
Clipboard.SetText("Test");
SendMessage((int)editHandle, WM_PASTE, 0, textToSendToFile);
我也得到了这个,但我真的不知道如何将它与上面的代码结合起来......
[DllImportAttribute("user32.dll", EntryPoint = "GetForegroundWindow")]
public static extern IntPtr GetForegroundWindow();
[DllImportAttribute("user32.dll", EntryPoint = "GetWindowThreadProcessId")]
public static extern uint GetWindowThreadProcessId([InAttribute()] IntPtr hWnd, IntPtr lpdwProcessId);
IntPtr hWndForegroundWindow = GetForegroundWindow();
uint activeThreadID = GetWindowThreadProcessId(hWndForegroundWindow, IntPtr.Zero);
