Build A Radar Connected To Laptop
Feb 20, 2009I'd like to build a radar connected to my laptop. I know there are computer programs that will allow me to do that, but as far as I know they require the radar to be operated via a built-in computer, but I want my laptop to act as its computer. How do I do this?

View 1 RepliesDisplaying Data Graphically (Ultrasonic Radar)?
Mar 20, 2012I'm working on an ultrasonic sonar and I would like to use the computer to display a standard green radar system detecting the objects.I'm using a micro controller with the software written in C to send out the sensor's angle and position and it works fine.On the computer side, I'm using Visual Basic 2010 to read the COM port which then contains the sensor's data in numbers (sensor's angle and distance between sensor and object) which is a constant stream. On the debug screen (Textbox) I can already see all the data coming through.
Now my question is: How do I convert those numbers into graphics?More explanations about these numbers I want to convert:I have a step motor to rotate the ultrasonic sensor, and it works that way: The motor advances 1 step forward, then measure distance between sensor and object, then send these 2 values out. So, if you see the attached file, those numbers on the text box mean:
000032 -> 000: step number & 032: 32cm between sensor and object
001031 -> 001: step number & 031: 31cm between sensor and object
002032 -> 002: step number & 032: 32cm between sensor and object
003007 -> 003: step number & 007: 7cm between sensor and object
and so on...
So those are the numbers I wish to convert into graphics. The scan line would need to rotate clockwise at same speed of the step motor. And then I would like to display dots when an object is detected.

Saving Window Size And Position Multiple Monitors Toolbar Position Etc.
Aug 24, 2009I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

View 3 RepliesGet Closest Position To Specific Position?
Mar 9, 2010I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:
Dim MyPosition as New Position()
MyPosition.X = 400
MyPosition.Y = 400
Dim tList as New List(Of Tile) = MyMap.GetTiles
Now, I can already do the stuff above, but what I need to make is something like this:
tList.GetTileClosestToPosition(MyPosition)

Mar 24, 2010I have two forms: Main and Options.Main can be moved around the screen (like a normal window).When the user clicks a button, the Options form opens up and the Main form HIDES.How do I set the Options form to open in the exact place that the Main form was last on the screen (to give it the effect the MAIN form never went into hidding)I was thinking to set Option form's StartPosition to Main's current position, but I don't know the syntax for that or if it's even something you can do.

View 6 Replies.net - Best Control To Draw In?
Aug 16, 2011I have a VB app which draws primitive shapes (lines, filled rectangles etc.) into a picturebox control (from its paint event). I've since found out that a picturebox is probably the worst control to use for this. I've also found out that it's better to draw directly onto the form but I don't really want to do this as a control gives clipping for 'free'.
What would be the best control for this? The panel control looks like a good candidate but the experiment I tried actually performed worse

Draw Graphics More Than Once?
Aug 21, 2010Running VB/Studio? 2010 on XP. I draw on full screen resolution of 1920 wide x 1080 hi.I have set FormBorderStyle to NONE & WindowState to Maximize which seems to be the only way to get rid of the task bar.but w or wout this setting, My graphics draws a full screen twice - mostly repeatably.When I have [code] parameters set to use 9/16th of screen horizontally, the pattern is drawn once the first time I run it and usually once if I hit F5 quickly enough after hitting Alt-F4. But if I wait long enough [a second or 2] after 'Ready' appears at teh lower left of the IDE screen, then it draws the pattern 3 times.for wider patterns, 10/16th, 11/16 up to 16/16, which is 1920 pixels wide, it usually draws the pattern once after I make this parameter change and twice from there on. The 'twice' is repeatable; it 'doing it once' the first time is not a sure thing.
There are more peculiaraities than this, but if we can find causes for what I"ve given you, it might get them all wout making it seem more complicated than it is.I don't think it's in my code; it works - it draws the right thing the right number of times w no compiler errors. But here is the guts of it:
Public Class Form1
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
e.Graphics.SmoothingMode = Drawing2D.SmoothingMode.HighQuality

Draw Over A Webpage?
Mar 31, 2012I have a small project where I need to draw graphics over a WEB page.
To do this, I create a "ghost" form with a WebBrowser at the same location and size of my main form that is always displayed behind my main form.
When I set the TransparencyKey of my form's Panel to the main form's TransparencyKey, the panel shows the WEB page that sits behind the form. Yet, because this is a panel, I can draw anything over the WEB page
The only problem that I have is when my program needs to open child non-modal forms. When the user sets the focus back to the main form, the child form goes behind me main form, but it is still in from of "ghost" form.
Is there a way to "bind" the main form and the "ghost" form together, so that any other forms may only be completely on the back, or comletely on the front (never in between)?[code]...
