How to set the height of a window using c#?
提问by Abs
Is it possible to set the height of a window using the window handle or process handle?
是否可以使用窗口句柄或进程句柄设置窗口的高度？
I have the following so far, assume the application in question is notepad.
到目前为止，我有以下内容，假设有问题的应用程序是记事本。
Process[] processes = Process.GetProcessesByName("notepad");
foreach (Process p in processes)
{
if (p.MainWindowTitle == title)
{
handle = p.MainWindowHandle;
while ((handle = p.MainWindowHandle) == IntPtr.Zero)
{
Thread.Sleep(1000);
p.Refresh();
}
break;
}
}
Can I make use of handleor pto set the height of the window?
我可以使用handle或p设置窗口的高度吗？

This is how I would do it:
这就是我将如何做到的：
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
namespace ConsoleApplication1
{
class Program
{
[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
public int left;
public int top;
public int right;
public int bottom;
}
[DllImport("user32.dll", SetLastError = true)]
static extern bool GetWindowRect(IntPtr hWnd, ref RECT Rect);
[DllImport("user32.dll", SetLastError = true)]
static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int Width, int Height, bool Repaint);
static void Main(string[] args)
{
Process[] processes = Process.GetProcessesByName("notepad");
foreach (Process p in processes)
{
IntPtr handle = p.MainWindowHandle;
RECT Rect = new RECT();
if (GetWindowRect(handle, ref Rect))
MoveWindow(handle, Rect.left, Rect.right, Rect.right-Rect.left, Rect.bottom-Rect.top + 50, true);
}
}
}
}
While you can do it with SetWindowPos, and SetWindowPosis the newer and more capable API, MoveWindowis just easier to call.
虽然您可以使用SetWindowPos, 并且SetWindowPos是更新且功能更强大的 API，但MoveWindow更易于调用。

You should be able to use the Win32 SetWindowPosfunction (use for both position and size). Here's a linkfor how to do it in C#.
您应该能够使用 Win32 SetWindowPos函数（用于位置和大小）。这是有关如何在 C# 中执行此操作的链接。
Here's a quick sample. This will move notepad to (10,10) on the screen, and resize it to (450,450):
这是一个快速示例。这会将记事本移动到屏幕上的 (10,10)，并将其调整为 (450,450)：
class Program
{
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, SetWindowPosFlags uFlags);
static void Main(string[] args)
{
Console.WriteLine("Start notepad and hit any key...");
Console.ReadKey(true);
Process[] processes = Process.GetProcessesByName("notepad");
foreach (Process p in processes)
{
var handle = p.MainWindowHandle;
SetWindowPos(handle, new IntPtr(SpecialWindowHandles.HWND_TOP), 10,10,450,450,SetWindowPosFlags.SWP_SHOWWINDOW);
break;
}
}
}
public enum SpecialWindowHandles
{
HWND_TOP = 0,
HWND_BOTTOM = 1,
HWND_TOPMOST = -1,
HWND_NOTOPMOST = -2
}
[Flags]
public enum SetWindowPosFlags : uint
{
SWP_ASYNCWINDOWPOS = 0x4000,
SWP_DEFERERASE = 0x2000,
SWP_DRAWFRAME = 0x0020,
SWP_FRAMECHANGED = 0x0020,
SWP_HIDEWINDOW = 0x0080,
SWP_NOACTIVATE = 0x0010,
SWP_NOCOPYBITS = 0x0100,
SWP_NOMOVE = 0x0002,
SWP_NOOWNERZORDER = 0x0200,
SWP_NOREDRAW = 0x0008,
SWP_NOREPOSITION = 0x0200,
SWP_NOSENDCHANGING = 0x0400,
SWP_NOSIZE = 0x0001,
SWP_NOZORDER = 0x0004,
SWP_SHOWWINDOW = 0x0040,
}
