Line and Shape Controls For Visual Basic Just Released

Line and Shape Controls For Visual Basic Just Released

  • Comments 10

The VB Team just released an updated version of the Visual Basic Power Packs on the VB Developer Center that includes a new set of controls for Visual Studio 2005 that allow you to draw lines, rectangle and oval shapes on your Windows Forms. These controls encapsulate many of the graphics methods that are contained in the System.Drawing namespace. This enables you to draw lines and shapes in a single step without having to create graphics objects, pens, and brushes. Complex graphics techniques such as gradient fills can be accomplished by just setting some properties. 

I don't know about you but I've been really looking forward to this release! 

Enjoy!

  • These shapes are great!  I have already redesigned my current application. I love the rounded corners!

    Thanks VB Team.

    Hey does anyone know how to make a label tansparent, through the gradient fill?

    Thanks!

  • Hi ,

            I liked the powerpacks but i amnot able to use the shape controls like  the other controls (in system.windows.forms ), when i am creating an instance of shape control and adding it to the picture box it is raising exception

    "Value of type'Microsoft.VisualBasic.PowerPacks.RectangleShape' cannot be converted to 'System.Windows.Forms.Control'.

    I want to use those controls like label,Tb,Checkbox and i want to add to the picturebox control .Is there any other way to create line,Rectangle ,oval and add to the picturebox .I reallly want these things in my application

  • Hi Dvsriram,

    You can't add the shapes to a picturebox control, instead use a panel and set the backgroundimage and then add the shape container and shapes to that. For instance,

    '-----------------------------

    Sub Setup()

           'setup the panel

           Dim p As New System.Windows.Forms.Panel

           p.BackgroundImage = My.Resources.MyPicture

           p.BackgroundImageLayout = ImageLayout.Stretch

           p.Dock = DockStyle.Fill

           'setup shape container

           Dim sContainer As New Microsoft.VisualBasic.PowerPacks.ShapeContainer

           sContainer.Dock = DockStyle.Fill

           'setup shapes

           Dim l As New Microsoft.VisualBasic.PowerPacks.LineShape

           Dim o As New Microsoft.VisualBasic.PowerPacks.OvalShape

           Dim r As New Microsoft.VisualBasic.PowerPacks.RectangleShape

           'setup line

           l.X1 = 100

           l.X2 = 500

           l.Y1 = 100

           l.Y2 = 500

           'setup oval

           o.Size = New System.Drawing.Size(500, 500)

           r.Location = New System.Drawing.Point(200, 200)

           o.BorderColor = Color.Blue

           'setup rectangle

           r.Size = New System.Drawing.Size(400, 400)

           r.Location = New System.Drawing.Point(100, 100)

           r.BorderColor = Color.Red

           'add shapes to shape container

           sContainer.Shapes.Add(l)

           sContainer.Shapes.Add(o)

           sContainer.Shapes.Add(r)

           'add shape container to the panel

           p.Controls.Add(sContainer)

           'add the panel to the form

           Me.Controls.Add(p)

       End Sub

    '-----------------------------

  • Thanks For giving the information ,

    I am creating panels at runtime on clicking a particular panel .Now i am able to create the control s , lineShape,RectangleShape ,OvalShape on panel (At runtime )which is generated at runtime .

    Now i have to do these things ::

    I used for this class for Control (Type ) selection & resizing from

    www.codeproject.com/KB/miscctrl/CSPickBoxSample1.aspx?df=100&forumid=23756&exp=0&select=1033576

    while creating a control as PickBox.WireControl(ControlName) .It taking care of Control(Type)(TextBox,etc ) selection& resizing .

    Now ,I need for moving and resizing controls (labels/textboxes/checkboxes/etc) and

    shape controls (LineShape ,RectangleShape, OvalShape which are from

    powerpacks.dll ) which i  place on the Panel which are generated at runtime .

    Is there any Class for creating Control Selection and Resizing Handles  which accepts any typeof controls which are present on the panel at runtime ??????

    I want to show the selection if user presses the control and able to resize

    those controls with resizing handles for Any Typeof control . ????? Line i want only 2 SizingHandles  at end points like that .

    ' If i release the mouse button after resizing it has to update the size or

    location of that control  same like in vs2005 design time environment but

    here at runtime .

    plzzz ,

  • I want a user to select & rezise a control at runtime using some grab handles on panel (also generated at runtime ) . Here i am having different controls that's the problem if i have normal control no problem .but here 4 Different controls RectangleShape,OvalShape,LineShape,Control (TextBox,....)

    THis is main meaning .Please do this favour for giving a nice thing .

    THanks & Regards

    Sriram

  • Dear Beth Massi

    The Power Pack elements like line or rectangle has constructor of Integer but I wanna single data type constructor. What do you offer for it.

    Another question is:How can I make a class that create line and rectangle objects(or component)

    Thanks a lot for your attention

  • I am actually trying to develop a ladder diagram drawing application, your method is very helpful. Can include text in shape container? Thank you very much

  • Hi Massi ,

    LineShape Control slipping from mouse pointer while moving at runtime

    Dim fdragging As Boolean = False

       Dim StartX, startY As Integer

       Private Sub LineShape1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles LineShape1.MouseDown

           fdragging = True

           StartX = e.X

           startY = e.Y

       End Sub

       Private Sub LineShape1_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles LineShape1.MouseMove

           If fdragging Then

               LineShape1.StartPoint = New Point(LineShape1.StartPoint.X + e.X - StartX, LineShape1.StartPoint.Y + e.Y - startY)

               LineShape1.EndPoint = New Point(LineShape1.EndPoint.X + e.X - StartX, LineShape1.EndPoint.Y + e.Y - startY)

           End If

       End Sub

       Private Sub LineShape1_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ShapeContainer1.MouseUp  ' Used for Handling MouseUP event bcoz not identifying event LineShp Mouseup

           fdragging = False

           StartX = 0

           startY = 0

       End Sub

  • Hi Beth,

    The example you have written was very nice, I could solve my problem. Thanks a million.

    Let me hope all the best for you.
