View 18 Repliesi am creating a winform program using vb where i am loading an image into a picture box. then in the mouse down event i am creating small circles which can act as points which will be displayed on the image. say creating five points around the eye of a bird. then i am having a button by clicking it , a polygon will be drawn on those selected circles x and y as edges. i am having no issues until this. when i am trying to add another polygon in the same picture by clicking around its leg or whatever and pushed the draw button there must be another polygon i.e. two separate polygons 1 on eye and 2 on leg. but there is only one polygon from eye to leg. so my questions are
1) how to close a polygon and draw another one in picture box
2) how to select a previously drawn polygon and delete it.

Can I draw my own shapes (such as a filled circle, square, etc.) on a form?Can it be done from code as well as from the designer?Can I use events such as onClick() on the shapes?
View 3 RepliesI want to use a loop to draw different types of shapes on a visual. I want to use the Random function sothat the number of each shape would be set randomly. For example, I want three triangles followed by two circles, followed by two triangles, etc. When you click the button again a different set of shapes would be rendered. I can draw shapes. What I need is how to use the loops and Random() to do this. I tried to use concatenation but it does not work with the Polygons.
View 15 RepliesThe aim of my program is to load a picture into an pic box, then to be able to place multiple shapes on the picture in the pic box by clicking on the location where i want the shape. The type of shape will depend on the radio button which has been selected. Basically all i want is choice of X or O. (its not tic tac toe either At the end of it all i want to be able to save the image WITH the shapes on it, doesnt matter what format its in (gif, jpg, bmp) as long as it has color and i can see the original image with the shapes included.
I have made several attempts at this, and this is what i have so far. (I am brand new to VB and programming so i need all the help i can get) I have hit a wall with how far previous examples can get me.

View 1 RepliesI would like to draw a rectangle on a form, for example to mimic a steel beam that is 6 metres long.Within this rectangle, there may be 4 "openings" or circles that mimic a diameter of 600mm, so i need to draw 4 circles within the rectangle, to indicate a beam that has 4 openings. Other issues I need to cater for is that one of the circles may not be in the centre, it may be slightly raised.The user can change the length of the beam and the size of the openings so i'd like to refresh my drawing to keep in line with this.

View 4 Replies[URL] In my Windows Form, I wanted the user to give an option to draw all over the form. But, if the user while drawing, enters the region 1, I want to assign a value to variable, say a=1. Correspondingly, if the user without leaving the mouse button previously enter the region 4, I want to b=1.After the user leaves the mouse button, I wanted to compare a and b. If both of them are equal, then Result=Done else not.

Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

I have a form in which I draw a rectangle and a line depending on the button click. I basically want a dynamic line/ rectangle that moves when the mouse is clicked on another point on the picturebox. I found some code online for a rectangle, and I'm trying to extend it to draw a line too, but i'm having some issues. The line is not displayed when the mouse is lifted(mouse up event).
Here's my code:
Public Class Form1
Dim selection As Rectangle = Nothing
Dim m_Drawing As Boolean = False
Dim m_Start As Point
Dim square_click As Boolean = False

View 6 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False
