If you display multiple windows in an SDI application, you need to carefully keep track of each one, usually by storing a form reference in some sort of static application class. With MDIs, you don t need to go to this extra work. That s because it s easy to find the currently active MDI window, the MDI parent, and the full collection of MDI children. Consider the next example, which provides a ToolStrip with two buttons: New and Close. The New button creates an MDI child window, while the Close button always closes the currently active window (see Figure 19-5). You don t need to write any extra code to track the currently active child. Instead, it is provided through the ActiveMdiChild property of the parent form. Here s the code: private int mdiIndex = 0; private void cmdNew(object sender, EventArgs e) { // Show a new child form. Child frmChild = new Child(); frmChild.MdiParent = this; mdiIndex++; frmChild.Text = "MDI Child #" + mdiCount.ToString(); frmChild.Show(); }

If the passwords do not match, then you will see the Passwords Do Not Match warning message, as shown in Figure 6-22. This message will appear when your computer detects the Windows Home Server on your home network.

type person = { name : string ; favoriteColor : string } let robert1 = { name = "Robert" ; favoriteColor = "Red" } let robert2 = { name = "Robert" ; favoriteColor = "Red" } let robert3 = { name = "Robert" ; favoriteColor = "Green" } printfn "(robert1 = robert2): %b" (robert1 = robert2) printfn "(robert1 <> robert3): %b" (robert1 <> robert3) The results of this code, when compiled and executed, are as follows: (robert1 = robert2): true (robert1 <> robert3): true Structural comparison is also used to implement the > and < operators, which means they too can be used to compare F# s record types. This is demonstrated here: type person = { name : string ; favoriteColor : string } let robert2 = { name = "Robert" ; favoriteColor = "Red" } let robert3 = { name = "Robert" ; favoriteColor = "Green" } printfn "(robert2 > robert3): %b" (robert2 > robert3) The results of this code, when compiled and executed, are as follows: (robert2 > robert3): true If you need to determine whether two objects are physically equal, then you can use the PhysicalEquality function available in the LanguagePrimitives module, as in the following example: type person = { name : string ; favoriteColor : string } let robert1 = { name = "Robert" ; favoriteColor = "Red" } let robert2 = { name = "Robert" ; favoriteColor = "Red" } printfn "(LanguagePrimitives.PhysicalEquality robert1 robert2): %b" (LanguagePrimitives.PhysicalEquality robert1 robert2)

private void cmdClose(object sender, EventArgs e) { // Close the active child. if (ActiveMdiChild != null) ActiveMdiChild.Close(); } The event handlers are treated as user interface commands (hence the names cmdClose and cmdNew). That s because they aren t linked to just one control. Instead, clicks on the menu and the ToolStrip are handled by the same event handlers.

Tip You also can set the active MDI form using the Form.Activate() method. This is similar to setting the focus for a control. It automatically moves the appropriate child form to the top of all other child forms and sets the focus to the most recently selected control on that form. Additionally, you can find the control that has focus on an MDI form by reading the ActiveControl property.

Figure 6-22. Your passwords do not match. Ensuring that the passwords match certainly makes more sense from an ease-of-use perspective, but if you are concerned about security and would prefer a different password, you can ignore this message and leave things as they are.

The MdiParent property allows you to find the MDI container from any child. The ActiveMdiChild property allows you to find the active child from the parent form. The only remaining gap to fill is retrieving the full list of all MDI children. You can accomplish this using the MdiChildren property, which provides an array of form references. (That s right, an array not a collection, which means you can t use methods like Add() and Remove() to manage MDI children.) The next example shows how you can use the MdiChildren array to synchronize MDI children. In this example, every child shows a text box with the same content. If the text box content is modified in one window, the custom RefreshChildren() method is called in the parent form.

The Operators module also offers a number of functions (see Table 7-1) specifically for floating-point numbers, some of which are used in the following sample:
