+Summary: WM_WINDOWPOSCHANGING not sent
+
+Description of Problem:
+WM_WINDOWPOSCHANGING does not appear to be sent (the constant with this 
+name in System.Windows.Forms.Msg is never used).
+
+Additional Information:
+This may be useful. While the following effect can be obtained by using 
+MinimumSize and MaximumSize, at the time it seemed the logical thing to do.
+
+using System;
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    const int FixedHeight = 100;
+    public TestForm() {
+        Height = FixedHeight;
+    }
+    const int WM_WINDOWPOSCHANGING = 0x0046;
+    struct WINDOWPOS {
+        IntPtr hwnd;
+        IntPtr hwndInsertAfter;
+        int x;
+        int y;
+        int cx;
+        public int cy;
+        uint flags;
+    }
+    protected override void WndProc(ref Message m) {
+        if (m.Msg == WM_WINDOWPOSCHANGING)
+            unsafe {
+                ((WINDOWPOS*)m.LParam)->cy = FixedHeight;
+            } 
+        else 
+            base.WndProc(ref m);
+    }
+}
