Draw Rectangle In A Circle?
Mar 12, 2011User 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).

Why Can't Draw The Rectangle Around The Picturebox Itself
Mar 29, 2011This code is used to demonstrate drawing a blue border around a picture box...(I've numbered the lines so I can refer to them below
1 Dim objGraphics As Graphics
2 objGraphics = Me.CreateGraphics
3 objGraphics.Clear(SystemColors.Control)
[code]....
Regarding line 1, the author says, "To instantiate an object in code, you create a variable that holds a reference to an instantiated object".!Regarding line 2, he says "the CreateGraphics method is pretty complicated, but for now, just know that it instantiates a new object that represents the client area of the current form".So now I have two new instances, the one from line 1 - an instance of a graphics object, and this one from line 2 representing the client area of the form.The rest of it is pretty clear; But Why can't I draw the rectangle around the picturebox itself? Why do I have to draw it around the "instance" of the picture box?
.net - Draw A Hollow Rectangle Using CreatePen?
Jun 25, 2011Since using the DrawArc function in GDI+ isn't very accurate when drawing a small rounded rectangle, I am using RoundRect instead.
Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
Dim hDC As IntPtr = e.Graphics.GetHdc
Dim rc As New Rectangle(10, 10, 64, 24)[code].....
This will draw a nice rounded rectangle, but it will also fill it with a white brush, erasing what I don't want to have erased.How can I draw this without erasing the inside of the rectangle?
Draw A Zoom Window Rectangle?
May 20, 2010I have drawn a diagram of lines on a panel using the g.DrawLine command. I want to be able to zoom in to the diagram and define the zoom area by two cursor picks. I get the coordinates of the picks and draw a rectangle using g.DrawRectangle. This works fine but as I move the cursor around, the rectangle becomes solid black (with all the DrawRectangle commands). In VB6 I used a rectangular shape on top of my diagram but you cannot do this in VB2008. I need something like drawing in XOR mode. Somehow as I move the cursor I need to undraw the old rectangle and draw the new rectangle.

View 1 RepliesDraw Invalidated Rectangle Using WM_PAINT?
Sep 23, 2011In order to draw a text over a ComboBox (or whatever else), I override WndProc() and catch 0x000F message -- which is WM_PAINT.Code is like the following:
Protected Overrides Sub WndProc(ByRef m As Message)
MyBase.WndProc(m)
If m.Msg = &HF Then[code].....
It works very well, but there is a problem: if I drag parent window on a side of the screen (in order to hide a part of the window form), the visible part of my control is infinitely redrawn. This makes the text redrawn over itself. I suppose there is a way to draw only invalidated (hidden) part of the control. How can I do?
EDIT:Here is the problem in one picture: http:[url].....(it's a link since I can't post image for now.)
UPDATE: I tried using BeginPaint API, but the RECT structure included in the returned PAINTSTRUCT structure contains only zeros.
If m.Msg = WM_PAINT Then
Dim ps As PAINTSTRUCT = New PAINTSTRUCT
BeginPaint(Handle, ps)[code].....
Can I do something with that? I don't know how to proceed, in order to paint only invalidated area.
Draw String On Top Of Rectangle Shape?
Oct 7, 2011I'm using e.graphics in the Me.Paint event to draw a string in the form. There is a rectangle shape with gradient in the form, and the string is supposed to be drawn on top of the rectangle shape. However, when I run the program, the string is drawn under the rectangle shape, and is therefore invisible... How do I fix this?

Draw A Rectangle In Picturebox In The Mousemove Event In Application?
Feb 14, 2012Actually I'm creating a simple paint application in VB.Net 2010. I want to draw shapes in my application same as we do in Microsoft Paint using mouse.
I'm a bit successful also using mousedown and mouseup events of a picture box. The mousedown event sets the starting point and mouseup event sets the ending point(diagonally opposite point of rectangle.) The problem is "Nothing seems to be occuring between mousedown and mouseup events(Well..that is obvious because I didn't add any code on mousemove event). My question is: "Can I do something to see a growing rectangle during mousemove event?". The rest of the drawing should remain unaffected.
Draw Rectangle And Line On PictureBox On Button Clicks

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:
