To print a point(.) on the given position from the formulas above.
Now heres my question how do I get Visual Basic too calculate:
x= (10 x CosA)+40
y=(10 x SinA) +20
360 times i.e 0rad-2Pirad and then pass the x & y [(x,y)] point to my cursor position code so that a '.' is printed at that position. I.e I will end up with a circle made out of 360 '.'
I would asume that a loop is used and also an array to store the 360 Pi values. I'm finding it extremely hard to even get Vb to calculate the Cos of an angle.
I am drawing a circle, of let's say 300 pixels diameter. I want to draw a triangle, with the top of it being at New Point(diameter / 2, 0). How could I get the other 2 points of the triangle? If possible, how could i get the 3 points of a triangle rotated by x degrees?
So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
Is is possible to draw graphics in a console application or is console limited to only text? If possible, where is a guide to the form of the graphics structures.
I've been having some trouble with a draw subroutine in a project I'm working on. The last time I did anything like this in VB, drawing on a form was as simple as calling the Line() function, so I'm not clear on a lot of these things. Here's my code:
Code: Private Sub drawBox(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles btnDraw.Click Dim blueBrush As New SolidBrush(Color.Blue) Dim i, j As Integer
[code]....
The code is just meant to draw a grid of small squares across the form, using the centers() array, which is set up elsewhere. My problem is that I can't figure out how to call this sub. If I use Handles Button.Click or Mouse.Move or something like that, VB returns an error saying that Draw and Mouse functions are incompatible. I can't call it normally, because I don't have values for sender and e.
I am really exhausted because I have been trying to find a way to draw 3D sphere which is spinning and have done nothing yet.. I am using visual basic studio. Part of my project is to draw solar system which includes a star and planets rounding about it and their stem. I want to create a class that create a planet with draw function and delete function to create movement.
I have really try to find something in the network but do nothing at all. First, I have read about XNA, but the tutorials seems to be quite complicated - after all, XNA is used for creating games, I need something more simple. I decided to use the directx libraries, read a lot about them but succeed only in draw rectangle (2D).
how to draw a dot (with XY position) in the radar.
Code: ' Draw the radar plot. Private Sub picCanvas_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles picCanvas.Paint ' Generate coordinates for the points.
Ok..I think it's very simple but I'm still a begineerI'll try to make it clear I need to draw a rectangle when I click on the button..what is the required code?
Quote: Public Class Form1 Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
I am trying to draw an image from a MS Access database by use of e.Graphics.DrawImage(New Bitmap()). In my database Row 0 Item 1 holds the path to the image I want to draw.
My current code looks like this:
Code: Private Sub pnlStart2_Paint(ByVal sender As Object, ByVal e As_ System.Windows.Forms.PaintEventArgs) Handles pnlStart2.Paint e.Graphics.DrawImage(New Bitmap(ds.Tables("Track1").Rows(0).Item(1)), 3, 3) End Sub
When I run my program I get the following message in my code: Illegal characters in path how I can draw the image from the database?
Is there any way to have 2d graphics that gets made by user through manual dimensions input be bound to a text box?
Is there any way to take position 1000,600 and make that zero? Can we make graphics by inputting only the next co-ordinate and have the pc automatically draw a line from last point?
Also, whats the difference between drawline and draw path? How can I get the shape to remain on screen when I toggle between pages?
Private Sub PictureBox1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint e.Graphics.DrawEllipse(Pens.AliceBlue, New Rectangle(New Point(0, 0), New Size(PictureBox1.Width, PictureBox1.Height))) End Sub
I am trying to draw a circle in VB.Net, .Net version 4.Nothing shows up in the paintbox.
Using Visual Basic 9 I want to draw a circle and gradientFill the circle using FillGradientStyle = Centraland a FillStyle = SolidWith the same results as can be achieved in The Power Packs 3.0 OvalShape.
I searched this forum for the answer before posting this and from what i have noticed there is no "simple" way ofcourse "simple" definition varies from one person to another
my definition of simple is something like this Line(x1,y1,x2,y2,color) or something like that.[code]...
User launches the application, enters width of circle, then enters width and height of rectangle and presses the button. Then app draws the circle with rectangle inside of it (if it fits). App should output the coordinates x1;y1 , x1;y2 , x2;y1 , x2;y2 (corners of rectangle) somewhere on form and would be great if it could post those coordinates on x and y axes (optional).
how to draw the circle at the below position, i have marked where i should get the angle. And i m also sending my piece of code.
Plz tell how to draw the circle at 180 degree on x-axis, For green circle. And later i should draw at the same place semi circle, dnt know how to draw them... i.e on green circle at zero n 180 degrees.
I am having some trouble drawing a circle that is constant when the program runs. right now I am able to create one of my clock hands (that is going counterclockwise), but I can't figure out how to draw the circle of the clock, any suggestions? [Code]
I need to write some code which draws a predefined circular path (say 48pix diameter) and use a timer to delay it to show it being drawn. I need to use GDI+ to do this. My guess is on the Timer.Tick, I would set some Point value for the next point on the path, and then call Invalidate to raise the Paint event.
is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...
Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?
Question: I need to draw pictures as below in C#/VB.NET Draw ishihara-transformations (circles in circle without intersection)?
Note that my problem is NOT drawing circles in C#.
My problems is drawing them without much whitespace and without intersection.
My thought would be using "Orbits" and then draw the circles with center on the "orbit" lines. (with some orbit lines for bigger and some only for smaller circles)
Im working on a project that needs to print a report of one client.Everything went smooth untill i came across my multiline input text data.When i display it in the PrintPagePreview the text go's outside my page. Even when im printing it only the halve of my text is displayed. I googled and looked everywhere but i can't get a clear fix for it.
I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.
drawing text on a window which is not the current form's window.I remember doing this in Win32 api with getwindowdc(handle) to obtain a DC for the Window, then textout() on the DC.
I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.
