在MDI表单上删除由于tablelayout pannel导致的凹陷边框 [英] Remove sunken border of due to tablelayout pannel on MDI form

问题描述

删除由MDL表格上的tablelayout pannel引起的凹陷边框。

解决方案

对于我在其他位置找到的解决方案，$ b $我发布此解决方案： -  
 1.在MDI上粘贴以下代码
< pre lang =cs>公共静态类MDIClientSupport 
 {
 [DllImport（& user32.dll& quot;）] 
 private static extern int GetWindowLong（IntPtr hWnd，int nIndex）; 
 [DllImport（& quot; user32.dll& quot;）] 
 private static extern int SetWindowLong（IntPtr hWnd，int nIndex，int dwNewLong）; 
 [DllImport（& quot; user32.dll& quot;，ExactSpelling = true）] 
 private static extern int SetWindowPos（IntPtr hWnd，IntPtr hWndInsertAfter，int X，int Y，int cx，int cy ，uint uFlags）; 
 private const int GWL_EXSTYLE = -20; 
 private const int WS_EX_CLIENTEDGE = 0x200; 
 private const uint SWP_NOSIZE = 0x0001; 
 private const uint SWP_NOMOVE = 0x0002; 
 private const uint SWP_NOZORDER = 0x0004; 
 private const uint SWP_NOREDRAW = 0x0008; 
 private const uint SWP_NOACTIVATE = 0x0010; 
 private const uint SWP_FRAMECHANGED = 0x0020; 
 private const uint SWP_SHOWWINDOW = 0x0040; 
 private const uint SWP_HIDEWINDOW = 0x0080; 
 private const uint SWP_NOCOPYBITS = 0x0100; 
 private const uint SWP_NOOWNERZORDER = 0x0200; 
 private const uint SWP_NOSENDCHANGING = 0x0400; 
 public static bool SetBevel（此Form表单，bool show）
 {
 foreach（控制c in form.Controls）
 {
 MdiClient client = c as MdiClient; 
 if（client！= null）
 {
 int windowLong = GetWindowLong（c.Handle，GWL_EXSTYLE）; 
 if（show）
 {
 windowLong | = WS_EX_CLIENTEDGE; 
} 
其他
 {
 windowLong& amp; = ~WS_EX_CLIENTEDGE; 
} 
 SetWindowLong（c.Handle，GWL_EXSTYLE，windowLong）; 
 //更新非客户区域。 
 SetWindowPos（client.Handle，IntPtr.Zero，0,0,0,0，
 SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | 
 SWP_NOOWNERZORDER | SWP_FRAMECHANGED）; 
返回true; 
} 
} 
返回false; 
} 
}< / pre> 
 2.使用MDI表单中的代码加密方法
< pre> this.SetBevel（假）;< /预> 

Remove sunken border of due to tablelayout pannel on MDI form.

解决方案

For this i found solution at another location,
i am posting this solution:-
1. Paste following code on MDI
<pre lang="cs">public static class MDIClientSupport
  {
      [DllImport(&quot;user32.dll&quot;)]
      private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
      [DllImport(&quot;user32.dll&quot;)]
      private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
      [DllImport(&quot;user32.dll&quot;, ExactSpelling = true)]
      private static extern int SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
      private const int GWL_EXSTYLE = -20;
      private const int WS_EX_CLIENTEDGE = 0x200;
      private const uint SWP_NOSIZE = 0x0001;
      private const uint SWP_NOMOVE = 0x0002;
      private const uint SWP_NOZORDER = 0x0004;
      private const uint SWP_NOREDRAW = 0x0008;
      private const uint SWP_NOACTIVATE = 0x0010;
      private const uint SWP_FRAMECHANGED = 0x0020;
      private const uint SWP_SHOWWINDOW = 0x0040;
      private const uint SWP_HIDEWINDOW = 0x0080;
      private const uint SWP_NOCOPYBITS = 0x0100;
      private const uint SWP_NOOWNERZORDER = 0x0200;
      private const uint SWP_NOSENDCHANGING = 0x0400;
      public static bool SetBevel(this Form form, bool show)
      {
          foreach (Control c in form.Controls)
          {
              MdiClient client = c as MdiClient;
              if (client != null)
              {
                  int windowLong = GetWindowLong(c.Handle, GWL_EXSTYLE);
                  if (show)
                  {
                      windowLong |= WS_EX_CLIENTEDGE;
                  }
                  else
                  {
                      windowLong &amp;= ~WS_EX_CLIENTEDGE;
                  }
                  SetWindowLong(c.Handle, GWL_EXSTYLE, windowLong);
                  // Update the non-client area.
                  SetWindowPos(client.Handle, IntPtr.Zero, 0, 0, 0, 0,
                      SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER |
                      SWP_NOOWNERZORDER | SWP_FRAMECHANGED);
                  return true;
              }
          }
          return false;
      }
  }</pre>
2.paste following code in MDI form load method
<pre>  this.SetBevel(false);</pre>
