QQ视频窗口最大化_.NET_编程开发_程序员俱乐部

闲着无聊，用C#做了一个QQ视频窗口最大化。

原理很简单就是WinApi的调用而已。

class="brush:csharp;gutter:false;">/// <summary>
/// 查询窗体
/// </summary>
/// <param name="lpClassName"></param>
/// <param name="lpWindowName"></param>
/// <returns></returns>
[DllImport("User32.dll", EntryPoint = "FindWindow")]
public extern static IntPtr FindWindow(string lpClassName, string lpWindowName);

/// <summary>
/// 获取窗体标题
/// </summary>
/// <param name="hwnd"></param>
/// <param name="text"></param>
/// <param name="maxLength"></param>
/// <returns></returns>
[DllImport("user32.dll")]
private static extern int GetWindowText(IntPtr hwnd, StringBuilder text, int maxLength);

/// <summary>
/// 设置窗体显示
/// </summary>
/// <param name="hwnd"></param>
/// <param name="nCmdShow">1-常规 2-最小化 3-最大化</param>
/// <returns></returns>
[DllImport("user32.dll", EntryPoint = "ShowWindow", CharSet = CharSet.Auto)]
public static extern int ShowWindow(IntPtr hwnd, int nCmdShow);

/// <summary>
/// 设置窗体是否置顶
/// </summary>
/// <param name="hWnd"></param>
/// <param name="hWndInsertAfter"></param>
/// <param name="x"></param>
/// <param name="y"></param>
/// <param name="Width"></param>
/// <param name="Height"></param>
/// <param name="flags"></param>
/// <returns></returns>
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern int SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int Width, int Height, int flags);

通过spy工具获取QQ视频窗体的类名是"TXGuiFoundation"

            IntPtr maindHwnd = FindWindow("TXGuiFoundation", null); //获得QQ窗体的句柄   
            if (maindHwnd != IntPtr.Zero)
            {
                //StringBuilder sb = new StringBuilder(255);
                //GetWindowText(maindHwnd, sb, 255);
                //MessageBox.Show(sb.ToString());
                ShowWindow(maindHwnd, 3);
                SetWindowPos(maindHwnd, -2, 0, 0, 0, 0, 0x001 | 0x002 | 0x040);
            }
            else
            {
                MessageBox.Show("没有找到窗口");
            }

    需要双击把视频窗口点击出来，运行代码既可。
