The picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.
I am drawing an arc within a square or a polygon with the maximum possible radius inside.When the arc is drawn within the boundary of the square or polygon,the arc length will intersect at few points on the square or polygon.How to find the coordinates of the intersecting points of arc at the periphery of the square/ polygon?
I'm working in .net 2005. I have a collection of points and I'm creating a polyline with them; however, I need to curve fit them so that they appear to be some what straighter.
If you look at my picture, you can see the blue dots represent the points and the red line is a represenation of how I'd like the final results to be. (Basically, I need to line to appear straighter and less jaggedy looking than it is now).
I didn't know if I should try to see if there's some plug-in for doing this or if vb.net has anything I could use to do this myself.
I am looking for a way to be able to export a beizer-curve (a curve like in the example below)from my app to a DXF-file.What I need is a way to calculate the control-points and parameters that DXF-format requires (format as in link below)
I have a button on vb form and its click event will call Windows to run "system32calc.exe" which is work great. My problem is I do NOT want to have multiple calculators running even if i click the button more than once. Is there any way to detect the calc.exe runing and then disable my button event to call calc.exe?
how to interface between Vb.Net and OpenOffice.org calc. I wanted to store and read back values from OpenOffice.org calc as we did in Excel from VB.net.
Env X is working on a calculator that needs some help to make it better.We have a button that will make the number either positive or negative.We have code that works but we want to make it better.Env X will give you the piece of code and see what you can do with it.[code]
I want to use calc.exe file in my vb .net program. I was trying this code but it not works as what I want.
Private Sub CalculatorToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculatorToolStripMenuItem.Click
Dim startInfo As System.Diagnostics.ProcessStartInfo Dim p As New System.Diagnostics.Process
startInfo = New System.Diagnostics.ProcessStartInfo("calc.exe") p.StartInfo = startInfo p.Start() p.WaitForExit()
When I click the menu to use the calculator, my system seem to hang and the background process is stopped.
What I want is, when I click to use the calculator, the background process is not stop. I only want we cannot touch the form at the back, I meant we cannot click the function at the back form untill the calculator is close. The calculator also should locate at the top of the form and cannot be minimized.
I am writing a few line of test code using Calc as a test on Sendkeys, but it does not seem to work correctly. Basically I am shelling out to Calc and trying to use Sendkeys to close it, but it is not working. [Code]
Using the attached code, the goal is to draw a series of 1x1 rectangles to produce an image of a line. The image begins okay at point (0,0) but ends up after 5600 passes through the loop at (1884,5273) instead of at (1965, 5244). To prove the scale factor accurate I also use Drawline to draw the entire line with the same scale factor. Drawline ends up at the correct location (1965,5244).
I've manually checked the calculations with the results as noted. I'm at a total loss to understand what's going on.
A couple of options seem to be available to achieve better accuracy and shorter periods than the Timer control in VB allows, however they too seem to have their own unique drawbacks. I am trying to plot (draw) points that are calculated in my VB application and then represent them in real time with an accuracy of a couple percent. If VB can calculate the points in the microsecond time range, would it be reasonable to hang an external pulse source on a usb port and use the "Datachanged" event to count the pulses that will be summed and used to plot the points?Ultimately, this is a machine control application that requires "reasonably precise" timing - ie. CNC type control. The points are scaled and drawn and then step and direction signals are sent out through another USB port.
Why my math keeps getting rounded to 0 decimal points by default?When I do this I get return value of 1
Private Sub Button4_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim numb1 As Integer numb1 = 100 / 78 MsgBox(numb1) End Sub
How to get that value up to two decimal points (like 0.00)?
I'm working on it for a couple of days but I couldn't get any success.. I'm trying to access Calc's edit box and trying to write something there but I couldn't do it =( what's wrong with my codes?
I have a large set of latitude and longitude coordinates from a GPS which, when plotted, creates a 'jerky' line over time. I would like to 'smooth' this line into another set of coordinates which I can then plot to make the track more 'smooth'.
I may need to add more intermediate coordinates to do this. I just wondered if there are any code snippets out there or even MS Excel functions
I'm not sure where I'm going wrong with this. it's supposed to let the user add scores to the list, then calculate the total, average, and count. However, it doesn't let me add more values to the list. Any help whatsoever would be awesome! Keep in mind, I am new to VB and programming languages, and was just playing around with code hoping for any sort of positive result, and therefore some of the code may not be necessary, or make sense. Here's what I have now:
Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
