The code in the load event of the PracticeWin form ensures that the FlowLayoutPanel wraps its contents and then calls a method to set up the form.
If you are not familiar with this technique for passing data from one form to another using a constructor, see this blog post for more information. This constructor receives the memorized text array and the blank count from the calling form. The next step is to define a constructor. It is defined here and not within the code that sets up the form to ensure that the application does not pick the same set of words to remove each time the user retries. The rnd variable is an instance of the Random class. This is needed for checking the user-entered values. The blanks generic Dictionary contains the list of random numbers and their associated TextBoxes on the form. The blankCount integer variable defines how many blanks should be inserted into the text. If that is not the case for you, you will need to add code to remove the punctuation and capitalization. For my kids, having the correct capitalization and punctuation in the memorized text was required. Notice that the array elements include the capitalization and punctuation. The memorizedText array consists of 15 entries, each containing a word from the text: For example, if the text to memorize is this: The memorizedText array contains the array of words in the order they appear in the text to memorize. But I thought it would be easier for cutting and pasting to put all of the code in and then explain it instead of having multiple pieces of code for you to paste in with lots of words around it. Loop While (numberOfBlanks memorizeText.Length) Then If Not blanks.ContainsKey(randomNumber) Then ‘ Ensure this random number was not already selected
RandomNumber = rnd.Next(0, memorizeText.Length) Private Sub PracticeWin_Load(ByVal sender As System.Object, _īyVal e As System.EventArgs) Handles MyBase.Loadīlanks = New Dictionary(Of Integer, TextBox) ‘ Add any initialization after the InitializeComponent() call.

‘ This call is required by the Windows Form Designer. Public Sub New(ByVal textToMemorize() As String, _ } while (numberOfBlanks memorizeText.Length)ĭim blanks As Dictionary(Of Integer, TextBox) Ensure this random number was not already selected Private void PracticeWin_Load(object sender, EventArgs e) Public PracticeWin(string textToMemorize, int intialBlankCount) In the PracticeWin form, insert the following code. Let’s start by coding the second form first. The first control is a FlowLayoutPanel set as follows:Īlso add an ErrorProvider (it shows up in the form’s tray) as follows: In this example, the first form looks like this: The user enters the text for the missing words.The form closes and a second form appears with the defined number of words removed.User identifies when this process is finished.User enters the set of text to memorize and the number of words to remove on one form.Some of their teachers helped them learn the verses using this technique. Going to a parochial school, my daughters had to memorize lots and lots and lots of Bible verses. Repeat this process until you can fill in the entire set of text with no words. Then blank out more words and fill them in again. One of the common ways to memorize a set of text is to read it several times, then blank out some of the words and attempt to fill them in. Using the ErrorProvider to show end-user data entry errors.Leveraging the FlowLayoutPanel to simplify control layout at runtime.Using the set of random numbers to pick a set of items from an array.Picking a unique set of random numbers.Passing data from one form to another on a constructor.Though this is not necessarily a common requirement, this post demonstrates the following techniques.
