Last week Microsoft released version 2.0 of the Visual Basic (.NET) Power Pack, and is freely downloadable here: Click to go to download. The Microsoft.VisualBasic.PowerPacks namespace contains classes for the Visual Basic Power Packs controls. Visual Basic Power Packs controls are additional Windows.

Introduction Microsoft has released version 2. Autocad 2012 Full Version 32 Bit Torrent. 0 of the Visual Basic 2005 Power Packs; the kit may be downloaded from here (Among other things, the kit contains a collection of drawing primitive controls in the form of an oval shape, a rectangle shape, and a line shape. Figure 1: Using the Drawing Primitives from the Visual Basic 2005 Power Pack 2.0 Installed Controls Upon installation of the tools; those items will appear in the toolbox under the heading of Visual Basic Power Packs v2.0.

Platinum Notes Free on this page. After the installation, you should see the Print Form, Line Shape, Oval Shape, and Rectangle Shape controls in the toolbox section. This article only addresses the drawing primitives. Adding to a Form In order to use a control, just drag the control from the toolbox and drop it onto the form as you would any other toolbox control; alternatively the controls may be added in code and added to the control collection.

Figure 2: Power Packs Section of the Toolbox Resize and Reposition Once the drawing controls have been added to the page, the user may click on a control which in turn results in the display of the controls resizing handles. With the resizing handles present, the user may resize the oval or rectangle, or resize and reposition the beginning and end points of the line. Figure 3: Manipulating a Control at Design Time Control Properties Each controls properties are exposed in the IDE property grid upon selection of the control. The user may set fill colors and styles, border thicknesses, gradient effects, and other control related properties from this interface. Such properties may also be manipulated in code at run time. Figure 3: Setting Control Properties in the Property Grid Control Events The controls are configured to respond to a number of common events, by writing event handlers for these events is it possible to create responsive instances of the controls. In the example provided, the three oval controls are configured to show a roll-over effect when the mouse passes into and out of the control, and to respond to a click event. The following code is used to alter the fill gradient color property of an oval control whenever the mouse enters the controls boundaries.

Private Sub OvalShape1_MouseEnter( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OvalShape1.MouseEnter OvalShape1.FillGradientColor = Color.CornflowerBlue End Sub And this code is used to restore the fill gradient color to its previous state once the mouse leaves the controls boundaries. Private Sub OvalShape1_MouseLeave( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OvalShape1.MouseLeave OvalShape1.FillGradientColor = Color.FromArgb(255, 255, 192) End Sub Here, a click event handler is added for the same control and is used to manage the visible property on three line symbol controls also added to this page. Private Sub OvalShape1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OvalShape1.Click LineShape1.Visible = True LineShape2.Visible = False LineShape3.Visible = False End Sub Summary Overall, the drawing primitives are a useful set of controls that may be used to enhance the appearance of an application GUI.
