I hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right

I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

I'm trying to calculate the direction between two points on a two-dimensional grid. Actually I want to determine if that vector is within a range of two values. Suppose the grid's origin is 0,0 at the upper left corner, and 0 degrees represents north. I have a point A on that grid. I want to know if a line from point A to point B on the grid is within a range of directions between 111.8 degrees (a little south of east) and 158.2 (a little east of south). Those are approximations; the 111.8 is 90 degrees plus the arctangent of 2/5, and 158.2 is 180 minus that value. I worked out a series of calculations worthy of a medieval astronomer, but I suspect there is a simpler way. I'm going to have to do this for a variety of other vectors, and I'd like to generalize

I'm using VS2010 and I've set up a form with a picturebox inside a panel and have zoom working via the mousewheel. The user can also pan by clicking and dragging the mouse. So all good so far. But I've struck a problem.
When I zoom it is anchored on the top left of the image.
What I would like to be able to do is have the user click a point and zoom on that point, or at worst a simple zoom on the center of what is displayed in the picture box.

I am able to draw points on a picture box. Add Labels to the points i draw. And delete the Labels at runtime.
It is the last part im having an issue with. Apparrently when i press the button to delete all the labels it does that because i can then start creating the labels again in the picture box starting at 0 again. But it leaves all the old labels visible on the screen. I assume i need to delete the Points to but this is beyond my current knowledge set.[code]...

how to remove text. For example, I am trying to get the username of the logged on user (e.g. Bryn)into a variable. I did this with variable = My.User.Name
However this also brought the domain with it (e.g. aaabbbcccBryn).
Is there anyway of getting rid of the domain? The App will be used on many domains, so removing the first, say, 9 characters won't be any good.

I need to move an ellipse from a known point on the screen to another known point on the screen.
I've tried using For.....Loops with less than desired results.
I can't remember everything I've tried, a lot of trial and error has been layed to waste. Lol
I've ended up with this code after putting together what I've tried, what I've learned elsewhere, and a couple of posts I've read on here.
All I want to do is move the ellipse from one point to the other along a straight line that forms the angle between the two points (X1,Y1) and (X2,Y2), make it grow from 2 pixels at it's start, to about 80 pixels by the time it reaches half way, then shrink from 80 pixels back down to 2 pixels by the time it reaches the point (X2,Y2).
Easier said than done.
Here's what I have at the present.....
Dim W As Integer
Dim H As Integer
Dim Num As Integer
[Code].....
....This seems like such a simple task, yet it's been a week since I came up with the idea, and I've had little success.

assuming i have an isoceles triangle, where i know the height + base width, how
can i calculate the width of that triangle at 1/3 of the distance from the point + 2/3 of the distance from the point?
i thought it'd be simply 1/3 base width + 2/3 base width, but my drawing is +/- a few pixels when i resize it?

If anyone has ever worked in the food industry, you are familiar with the P.O.S. system that you place orders into. If a company adds a new menu Item, they don't have to rehire the programmer to code in the button, there is a script in place that will allow them to add their own buttons.

I work for a Aerial advertising company, and am trying to build a app that will measure a distance from one zip code to another, and then spit out a price (like if somebody wanted to fly a "Please Merry me" banner for their girlfriend) based on that distance (in air miles, not road travel). I guess I will have to use a Map api, but how in the world do I do this? I have built a very basic app, so I know some progamming, but I have never used a API.
