如主题中...或更好 - 如何在顶部窗口更改时从事件中获取此信息?
最佳答案
感谢提示。所以无论如何我都应该使用 P/Invoke。完整代码如下:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace CuckooCoach
{
class Monitor
{
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
static extern int GetWindowTextLength(IntPtr hWnd);
// int GetWindowText(
// __in HWND hWnd,
// __out LPTSTR lpString,
// __in int nMaxCount
// );
[DllImport("user32.dll")]
private static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount);
// DWORD GetWindowThreadProcessId(
// __in HWND hWnd,
// __out LPDWORD lpdwProcessId
// );
[DllImport("user32.dll")]
private static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);
//HANDLE WINAPI OpenProcess(
// __in DWORD dwDesiredAccess,
// __in BOOL bInheritHandle,
// __in DWORD dwProcessId
//);
[DllImport("kernel32.dll")]
private static extern IntPtr OpenProcess(uint dwDesiredAccess, bool bInheritHandle, uint dwProcessId);
[DllImport("kernel32.dll")]
private static extern bool CloseHandle(IntPtr handle);
// DWORD WINAPI GetModuleBaseName(
// __in HANDLE hProcess,
// __in_opt HMODULE hModule,
// __out LPTSTR lpBaseName,
// __in DWORD nSize
// );
[DllImport("psapi.dll")]
private static extern uint GetModuleBaseName(IntPtr hWnd, IntPtr hModule, StringBuilder lpFileName, int nSize);
// DWORD WINAPI GetModuleFileNameEx(
// __in HANDLE hProcess,
// __in_opt HMODULE hModule,
// __out LPTSTR lpFilename,
// __in DWORD nSize
// );
[DllImport("psapi.dll")]
private static extern uint GetModuleFileNameEx(IntPtr hWnd, IntPtr hModule, StringBuilder lpFileName, int nSize);
public static string GetTopWindowText()
{
IntPtr hWnd = GetForegroundWindow();
int length = GetWindowTextLength(hWnd);
StringBuilder text = new StringBuilder(length + 1);
GetWindowText(hWnd, text, text.Capacity);
return text.ToString();
}
public static string GetTopWindowName()
{
IntPtr hWnd = GetForegroundWindow();
uint lpdwProcessId;
GetWindowThreadProcessId(hWnd, out lpdwProcessId);
IntPtr hProcess = OpenProcess(0x0410, false, lpdwProcessId);
StringBuilder text = new StringBuilder(1000);
//GetModuleBaseName(hProcess, IntPtr.Zero, text, text.Capacity);
GetModuleFileNameEx(hProcess, IntPtr.Zero, text, text.Capacity);
CloseHandle(hProcess);
return text.ToString();
}
}
}
