Erasing rectangle drawn with DrawRectangle

Dan
I want to use Graphics.DrawRe ctangle to draw a rectangle at a position on the
screen, and then a few seconds later, erase it. How do you erase a rectangle
that you just drew (without affecting the original background of the
window(s) behind the rectangle)?

Thanks...

If you force the background object (form, control, etc) to repaint
itself. You can use the invalidate method I believe.

Try ControlPaint.Dr awReversibleFra me. Call it once to draw, call it again
with the same args to erase. The disadvantage is that you can't precisely
control the rectangle's color.

I am having a hard time understanding the logic behind the Rectangle object. My problem has to do with the way the rectangle treats the "Width" property. For example, take the following rectangle object. Rectangle myRec = new Rectangle(0, 0, 2, 2); If you draw this rectangle on the screen you will end up with a rectangle like the one shown below (The character "X" represents a pixel used to draw the rectangle and the character "O" is...

Hi, this is a really simple question I have been banging my head on a brick wall over. The program below changes the background colour of a form depending on whether the cursor is inside a rectangle drawn on the form or not. It works perfectly as shown below. But it won't work if I change the values of scaleFactor, rotateFactor, translateFactorX, translateFactorY in the program. I would like to 'correct' the values of e.X and e.Y in...

Hey folks, I'm trying to make my own progressbar. The idea (for my test) is a rectangle that is 1/60 filled with a color per second (so after a minute it is all filled). This is what I have so far: Public Sub DrawRectangleFloat(ByVal e As PaintEventArgs)

I have a rectangle around text that I want to fill in with color. I do not know the height of the rectangle until I actually go through and draw out the text. Is there a way of filling in the rectangle that will allow the text to show through? I did try: myColor = Color.FromArgb(127, Color.GreenYellow) Dim fillBrush As New SolidBrush(myColor) but that isn't exactly the effect I wanted.

Hi, Now I can get the rectangle to draw, but it seems the rectangle is not visible. The following code is used to draw the rectangle. Hope someone can help. Thanks very much! SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); Pen pen = new Pen(brush, 4); Graphics formGraphics = Graphics.FromHwnd(this.axWebBrowser.Handle);

Hello All, I'm trying to solve a nagging problem. The goal is to draw a rectangle over the top of all the other controls on a form. Specifically, over a ChartFX control.

I haev been able to draw the rectangle on a blank form but I cannot get it to draw on top of other controls. I have pasted in the code i am using ....

I'm drawing text using the DrawString method. I need a way to go back and erase one or more characters. As a first thought it seemed that one way to do it would be to go back to the character(s) I want to erase and merely re-write the same character(s) using a brush whose foreground color is the same as the background color. The following code does that: protected override void OnPaint(PaintEventArgs pea) { Graphics grfx =...
