C# - Getting X-coordinate On Chart From Mouse Click?
Mar 22, 2012I have a chart on a Windows Form with several line graphs. I would like to be able to get the x-coordinate from a mouse click on the chart in such a way that the user would be able to place vertical annotations on the chart at the location of the click. I looked at the Chart.HitTest function, but that will only do what I need if the user clicks on a data point, not anywhere in the chart area.

Mar 31, 2011Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
Label5.Text = "X:" & e.X
Label6.Text = "Y:" & e.Y

Dim objectrect As Rectangle = rects(0)
Dim object_x As Integer = objectrect.X

I discovered that these labels are not the same, the mouse move is more accurate. My mouse is currently pointing at the upper left corner of rectangular.

Aug 23, 2011I can't get a simple answer to this. I have pixel coordinates, I want to print an image in a (landscape) page at those coords.In my printing event I do:

This obviously doesn't work: I specify pixels but the driver expects inches(?) or what?
Tried to: e.Graphics.PageUnit = GraphicsUnit.Inch with no luck.I'd like a conversion method like:

View 18 RepliesBest Approach To Store Node Coordinate Data
Dec 24, 2009I have a question on the best way to store model data for my app. My app will basically be drawing a bunch of elements (lines) connected to a node at each end. Im trying to decide how im going to store my node data (as well as element data). The node data im trying to store will consist of the node XYZ coordinates and some other info about the node. The element data will consist of the node numbers at each end plus additional info about the element. There a number of ways i've been thinking i can do this. They are:
1) Store my node/element data as a Dictionary object, where the key represents the node/element, and the value would be an array of the information i want to store.
2) Create a "Node" structure and an "Element" structure to store the info i want. Im a bit worried here as my model could potentially have thousands of nodes and elements.
3) Create a "Node" datatable and an "Element" datatable, and store my info in those instead. I can see some advantages in this in regards to displaying information to the user in datagridview etc. But then again i can easily pull the required data from a method i mentioned above, and generate the datatable when required.
Not quite sure what the best approach is. Either way i do it, i will be serializing whatever object i use to save the data to disk.

View 5 RepliesForms :: Trying To Coordinate Start And Stop Buttons
May 21, 2009I'm very new to Visual Basic, and have just installed VB Express 2008 from a Sams book titled, "Teach Yourself Visual Basic 2008 in 24 Hours", by James Foxall. I've managed to make it through most of the book, which was very helpful in getting a quick jump start, but I find that I am still "not quite getting it" yet.
I've written a program that has a "Start" and "Stop" button which are suppose to control the logging of data through a serial port. When I click the Start button, the serial port gets initialized, opened, and then I go into a Do-Loop-Until loop to process the incoming data stream, and that is suppose to stop when the Stop button is pressed. However, I haven't figured out how to implement that.

View 2 RepliesFast Update Of Bitmap From Polar Coordinate Data?
Sep 7, 2011I am producing a marine radar display in VB.Net and struggling to get the radar data to display quickly enough.The data is coming into my application from a callback from the radar maker's dll. Each dataset consists of an integer between 0 and 8191 denoting the angle from the datum (ship's head) that the dataset represents and a byte array with 480 elements containing data from ship's position (byte 0) to maximum range (byte 480). Each of these locations is a single byte, I want to set both red and green components of the relevant pixel in a 1000 x 1000 bitmap to this byte value. The dataset number increments round from 0 to 8191 as the radar scanner rotates.
My first approach was to use math.sin and math.cos to convert polar coordinates to cartesian coordinates, and then use setPixel to set the colour of the relevant pixels but this is far too slow.I'm now trying to use Boop Boops 'FastPix'
[URL]
Which looks like it should be much better, but I am wondering if there is a more efficient approach, for example cutting out the polar to cartesian conversion, or putting the data direct into a byte array?I am also running the radar picture processing code on a thread separate to the UI thread to keep the UI responsive - what is the best way to display the resultant bitmap onto the UI? I am currently using a delegate and putting the bitmap into a picturebox?
Game Programming :: Coordinate Based 2D Map And Waypoint System
Dec 16, 2010I am reading the memory from a game and I have managed to find the x,y,z values of the player (z is irrelevant). Now I am trying to make some sort of a waypoint system and I thought it would be best to make a small coordinate based map that will act as a birds-eye view of whats going on ingame. But I don't know where to begin creating this thing, since it needs tons of xyz values.Just throwing this in here since I've already made the thread:I also want a small circle to represent the player that will turn, facing waypoint 1 and move in a straight line towards it.
