MSDN Visual Basic Community TitleUse a TabControl with owner-drawn tabs in Visual Basic .NET DescriptionThis example shows how to use a TabControl with owner-drawn tabs in Visual Basic .NET. KeywordsTabControl, OwnerDraw, owner drawn, tab, control, DrawMode, OwnerDrawFixed, VB.NET CategoriesControls, VB.NET To make an owner drawn tab control, the code sets the control's DrawMode property to OwnerDrawFixed. The SizeMode must be Fixed if the program needs to change the tab size. This example does change the size to 10 pixels wide and 6 pixels taller than the initial default. ' Set OwnerDraw mode.Private Sub Form1_Load(ByVal sender As System.Object, ByVal _ e AsSystem.EventArgs) Handles MyBase.Load ' We will draw the tabs. TabControl1.DrawMode = TabDrawMode.OwnerDrawFixed ' SizeMode must be Fixed to change tab size. TabControl1.SizeMode = TabSizeMode.Fixed ' Set the size for the tabs. Dim tab_size As Size = TabControl1.ItemSize tab_size.Width = 100 tab_size.Height += 6 TabControl1.ItemSize = tab_sizeEnd Sub When the control needs to draw a tab, it raises its DrawItem event handler. This routine gets the tab's area by using the control's GetTabRect method. This returns a rectangle slightly different from the one in the e.Bounds parameter and is the rectangle that we can use later in the MouseDown event handler.DrawItem then checks the e.State parameter to see whether the tab is selected and picks colors accordingly. It fills the tab's background and, if the tab is selected, it draws a focus rectangle on it.Next the code makes a rectangle representing the tab's area minus some margins. It uses this rectangle to position the tab number in the upper left corner and the tab's text centered. The program then draws an X in the upper right corner. ' Draw a tab.Private Sub TabControl1_DrawItem(ByVal sender As Object, _ ByVal e AsSystem.Windows.Forms.DrawItemEventArgs) Handles _ TabControl1.DrawItem Dim txt_brush As Brush Dim box_brush As Brush Dim box_pen As Pen ' We draw in the TabRect rather than on e.Bounds ' so we can use TabRect later in MouseDown. Dim tab_rect As Rectangle = _ TabControl1.GetTabRect(e.Index) ' Draw the background. ' Pick appropriate pens and brushes. If e.State = DrawItemState.Selected Then e.Graphics.FillRectangle(Brushes.DarkOrange, _ tab_rect) e.DrawFocusRectangle() txt_brush = Brushes.Yellow box_brush = Brushes.Silver box_pen = Pens.DarkBlue Else e.Graphics.FillRectangle(Brushes.PaleGreen, _ tab_rect) txt_brush = Brushes.DarkBlue box_brush = Brushes.LightGray box_pen = Pens.DarkBlue End If ' Allow room for margins. Dim layout_rect As New RectangleF(

Left edge of its containter. Name The string value used to refer to the control in code. Image Specifies the graphic to be displayed in the control. TabIndex Specifies the tab order of a control within its parent form, TabStop Specifies whether or not the user can use the Tab key to give focus to the control. Tag A string containing extra data associated with the control. Top Specifies the distance (in pixels) between the internal top edge of a control and the top edge of its containter. Visible Specifies whether the control is visible or hidden. Width Specifies the width of the control in pixels. Common Methods of Visual Basic .NET ControlsMethodsare blocks of code designed into controls that tell the control how to dothings, such as move to another location on a form. Just as with properties,not all controls have the same methods, although some common methods do exist,as shown in the table below: Method Description Focus Gives focus to the object specified in the method call Move Changes an object's position in response to a code request Drag Handles the execution of a drag-and-drop operation by the user Common Events of Visual Basic .NET ControlsEvents are what happen inand around your program. For example, when a user clicks a button, many eventsoccur: The mouse button is pressed, the button in your program is clicked, andthen the mouse button is released. These three things correspond to theMouseDown event, the Click event, and the MouseUp event. During this process,the

ZylBurnerAX 1.73 ActiveX Control ZylBurnerAX is a CD / DVD / Bluray burner ActiveX control. It is based on NeroCmd utility, so it needs Nero Burning ROM to be installed. This component is very easy to use, it's ideal for developers for quick CD / DVD / Bluray writing purposes. The control works in two modes: synchronous mode and asynchronous mode. In synchronous mode the operational functions (Burn, Erase, WriteImage, Eject) always wait for the end of the current operation and return a value which indicates if the operation was successful or not. In synchronous mode the return value of the operational functions is always 0, and the functions don't wait for the end of the current operation. You can use it to burn data CDs / DVDs / Blurays, audio CDs, video CDs, supervideo CDs and video DVDs. The demo version is fully functional, but it displays a nag dialog (the licensed version will, of course, not have a nag dialog). The package includes demo programs and a help file with the description of the control. Supported Operating Systems: Windows 95/98/Me/NT/2000/XP/Server2003/Vista/Server2008/7/8/Server2012/10 Requirements: Nero 6.x or later ( necessary also for distribution for every PC Installation: -Installation into Microsoft Visual C#.Net/ Microsoft Visual VB.Net: To install the ActiveX Control into Visual Studio, click "Tools->Add/remove Toolbox Items..." menu item, select "COM Components" tab in "Customize Toolbox" window, click and choose "ZylBurnerAXControl" and press "OK" button. After this you can drag and drop the control to the form and use all methods and events provided. -Installation into Microsoft Visual C++.Net/ Visual C++ 6.0: To install the ActiveX Control into Visual Studio, right-click the form and select "Insert ActiveX Control" menu item, select "COM Components" tab in "Customize Toolbox" window, click and choose "ZylBurnerAXControl" and press "OK" button. After this the control will be added to the form and you can use all methods and events provided. -Installation into Microsoft Visual Basic 5-6: To install the ActiveX Control into Visual Basic, click Project->Components menu item and choose "ZylBurnerAXControl".
