Finding Area And Perimeter Of A Rectangle?
Sep 8, 2009OK, so I just started this VB programming class at school. But I don't understand much because the teacher doesn't really teach us. He just types everything on the projector and expects us to keep up. We have this project in which we are supposed to build a form that accepts the length and width of a rectangle, and calculates the area and perimeter of the rectangle. CAN SOMEBODY PLEASE HELP ME?? I really have no clue how to do this, and more than half the other people in our class don't either, so finding help within the class is pretty much out of the question.
The user enters values for the length and width of a rectangle and clicks the Calculate button or presses the Enter key to activate that button. The application then displays the area and perimeter of the rectangle in the third and fourth labels on the right side of the form.
Specifications The formula for calculating the area is width * length. The formula for calculating the perimeter is 2 * width + 2 * length. The application should accept fractional decimal entries like 10.5 and 20.65. Assume that the user will enter valid numeric data for the length and width.
Find The Area Of A Circle Which Is Inside A Rectangle?
Jun 24, 2011I'm writing a .NET program for an engineering company. Their specification is to find the number of holes (either of same or different radius) on a rectangular plate and then to find the area of the rectangle and also area of the circle inside that rectangle. It's not essential that the circle touches the rectangle.

Dec 5, 2010Drawing text on a picbox I notice if the picbox has a border style set then the TextRenderer.DrawText rectangle area needs to be adjusted slightly otherwise text may be drawn very near the picbox borders and the text doesn't look as clean, but I'm not sure what those offsets should be, I hard coded them in, see code under "' area to draw". btw, the code draws the first word of text in bold and then the other words as regular.

Finding The Brightest Area In An Image?
Aug 5, 2009I'm working on a small project for the fun of it. One of my hobbies is astro-imaging and I take pictures of planets, nebulae gallaxies etc . One of the more challenging targets is the International Space Station. I have had some success with the ISS by manually aiming my telescope as the Station moves across the sky.
What I am trying to achieve is to write a program that will lock onto the brightest area of a webcam image. If the brightest area (which will be the ISS) is off center, then commands are sent to the telescope to recenter it.
So far I have been able to write code that talks with the scope, and I have been able to get a webcam stream to show on a Form.
So the last piece of the puzzle (well I am sure there will be other things that have to be worked out) is to identify the brightest area of the image. I am scratching my head as to how I should accomplish this.
I'm thinking I should dump pixel information into an array maybe, and establish which line and column has the brightest average values (I could then draw a cross hair over the image).

Convert Visible RichTextBox Area Into Image Object?
Aug 12, 2009I'm working on a Vb.net project. I have a form with a RichTextBox or a simple TextBox control. It contains hundreds of text lines, so the control has to be scrolled.
I want to send to a printer only the lines that are currently seen on the control window.
That is, I want to convert what I see into an Image and then draw that image thru e.Graphics.DrawImage.
As you can see, it could also be the case of a ListBox, a TreeView or any other scrollable control.
How can I grab that rectangle area and then convert it into an Image? The rest I already know how to do it.

VS 2008 Translucent Layer On Form?
May 12, 2010I am using normal windows form application. I wanted a way whereby I could create a layer over my form which would be semi transparent and nothing would be accessible until I click a button or do something like that. What I want is similar to a grey sheet that covers your screen in vista or 7 when user admin Yes/No box is displayed. Nothing is accessible behind. Or as you might see in some webpages where till we dont click a button or so the content behind is inaccessible.
Actually I want this to apply only on my mdi child form (a particular one) and it should enable me to see whats in the form but semi transparent and till i dont click a button on it, the content behind should'nt be accessible. Kinda like what you see in webpages whereby there is a button in the center and till you dont click it you can't select or click on content behind it.
