Experimental Section VB programming skills [Abstract] In this paper, experimental courses VB point of view, in order to enable students to grasp a more in-depth programming skills, introduced several popular and typical programming skills. Visual Basic programming using visualization techniques to avoid the many details of process-oriented language. Therefore, students more easily grasp the basic knowledge of VB programming. Experiments on the VB class, it should be as many programming exercises. This article describes few of the more typical programming skills, hoping to help the students to learn VB. [Keywords:] VB programming skills experimental courses First, create a custom cursor In the design of an application, Visual Basic properties of a number of controls allow the programmer MousePointer pre-defined shape of the mouse cursor among a number of optional one. However, in the application, and sometimes want to appear different from the pre-defined shape of a cursor. You can add the code to change the control’s MouseMove and DragOver events. The following examples illustrate when the mouse pointer moves to a control when, how to change into different shapes. First, create a form Form1. In the Form1 to add a text box control Text1. DragIcon property of the Text1 control the settings dialog box, select a pointer to the shape (. ICO file). Add the following code to the MouseMove event of Text1: Private Sub Text1_MouseMove (Button As Integer, Shift As Integer, X As Single, Y As Single) Text1.Drag 1 ‘icon on End Sub Add the following code to Form1’s DragOver event: Private Sub Form_DragOver (Source As Control, X As Single, Y As Single, State As Integer) Text1.Drag 0 ‘icon off End Sub To run this program. Move the mouse pointer to the text box control when the program would have selected. ICO file as the default mouse cursor; the mouse pointer to leave the control, the cursor will automatically revert to the default shape. Other controls can also b
