winform顶部的记事本

本文关键字：记事本 顶部 winform | 更新日期: 2023-09-27 18:19:48

大家好，有人能帮我吗？我有一个设置TopMost = true的winforms。我有一个按钮，当我点击它时，它会创建一个记事本。现在，我希望我的记事本显示在我的winforms的顶部，而不需要设置我的winform TopMost=false。也许我错过了什么。我愿意接受任何建议。顺便说一句，我把我的表单设置为TopMost=true和BringToFront()，因为我不希望任何用户在任务栏上选择任何程序，然后把它放在前面，最小化我的winforms。提前感谢

public Form1()
{
    InitializeComponent();
    this.BringToFront();
    this.TopMost = true;
}
// bunch of codes here...
private void button1_Click(object sender, EventArgs e)
{
    Process process = new Process();
    process.StartInfo.FileName = "notepad.exe";
    process.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
    process.Start();
}
// some codes here
private void Form1_Load(object sender, EventArgs e)
{
    FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
    Left = Top = 0;
    Width = Screen.PrimaryScreen.WorkingArea.Width;
    Height = Screen.PrimaryScreen.WorkingArea.Height;  
}

PInvoke解决方案：

using System.Runtime.InteropServices;
...
// Even if it is "user32.dll" it will do on IA64 as well
[DllImport("user32.dll", SetLastError = true)]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, 
                                int X, int Y, int cx, int cy, int uFlags);
 ...
// Since Process is IDisposable, put it into "using"
using (Process process = new Process()) {
  process.StartInfo.FileName = "notepad.exe";
  process.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
  process.Start();
  // wait for main window be created
  process.WaitForInputIdle();
  // Insert (change Z-order) as the topmost - (IntPtr) (-1); 
  // NoMove, NoSize - 0x0002 | 0x0001
  SetWindowPos(process.MainWindowHandle, (IntPtr) (-1), 0, 0, 0, 0, 0x0002 | 0x0001);
}
