Visual Basic features and characteristics VBA and Visual Studio are the two frameworks most commonly used today. NET, Visual Basic for applications (VBA) and Visual Stuido. The last version of VB, Visual Basic 6, was released in 1998, but has since been replaced by VB. VB is intended to be easy to learn and fast to write code with as a result, it is sometimes called a rapid application development ( RAD) system and is used to prototype an application that will later be written in a more difficult but efficient language. VB is derived from the BASIC programming language and is considered to be event-driven and object-oriented. Private Sub SaveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveButton.ClickįileWriter.WriteLine(RadioButton1.Name & '|' & ())įileWriter.WriteLine(RadioButton2.Name & '|' & ())įileWriter.Visual Basic (VB) is an event-driven programming language and environment from Microsoft that provides a graphical user interface ( GUI) which allows programmers to modify code by simply dragging and dropping objects and defining their behavior and appearance. RadioButton2.Checked = Boolean.Parse(prop(1)) RadioButton1.Checked = Boolean.Parse(prop(1))ĮlseIf String.Equals(prop(0), RadioButton2.Name) Then RadioBtn.Checked = Boolean.Parse(prop(1))ĮlseIf String.Equals(prop(0), RadioButton1.Name) Then ' If ComboBox Component set it's propertyĮlseIf String.Equals(prop(0), comboBox.Name) ThenĬomboBox.SelectedIndex = Integer.Parse(prop(1))ĮlseIf String.Equals(prop(0), radioBtn.Name) Then If String.Equals(prop(0), textBox.Name) Then 'Read the next line and split its value based on the | character If File.Exists('c:tempsampleFile.txt') Then Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Clickĭim prop(2) As String ' define array of length 2

Private Sub CloseButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CloseButton.Click Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load The example contains basic error checking including validating that the saved file exists, however it does not validate the data in the file is of the correct format and not corrupted.

To see the full example of how the data is processed please view the full source code below.Īfter the loop close the FileReader as all the data has been read.įor those that learn better by example below is a Simple Class that holds a complete example of saving data to a File from a Form in addition to loading the saved data from the form and setting the components to the correct state.

In the below example we will read in the file’s contents 1 line at a time. Iterate until the End of File is reached.In this case we will utilize the StreamReader class of the System.IO package.ĭim FileReader As StreamReader ' define the File ReaderįileReader = New StreamReader('c:tempsampleFile.txt', False) After you have read all the data you would lastly close the File. First you want to open up the file, then you want to read a line of data, single character, or etc depending on how you are going to process the data until you reach the end. The process for reading information out of a File is similar to the writing process. This step is optional however as the Close function will call Flush if needed.įileWriter.Flush() ' optional as close will flush However if you want you can first call Flush to have the data written out. To complete your write you simply need to call Close on your writer. For a text field saving the Text is appropriate while when using a check box or radio button you will want to save the Checked property.įileWriter.WriteLine(textBox.Name & '|' & textBox.Text)įileWriter.WriteLine(comboBox.Name & '|' & ())įileWriter.WriteLine(radioBtn.Name & '|' & ()) In the case of forms you may want to write different data. To write data to the file you can utilize the WriteLine function. I will assume for these instructions that you have imported the System.IO library.ĭim FileWriter As StreamWriter ' define the stream writerįileWriter = New StreamWriter('c:tempsampleFile.txt', False) In this case we will utilize the StreamWriter class of the System.IO package. They include opening up a writer to a specified file, writing the contents, and then closing the writer when completed. The process for saving data to a file is pretty straightforward in Visual Basic. In this short tutorial I will show you the basic steps to save a form’s information to a file and then load up the contents of the saved file.

A common task when creating a form based windows application is to allow a user to save their information and to also load saved information.
