VS 2008 : Microsecond Timer To Plot Points On Line?
Feb 27, 2012A 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.

View 12 RepliesMove To The Next Line In The Txt File?
Jan 25, 2011I have a text that has a question followed by four possible answers. At the start, it loads up line 1 of the text file and puts the sentence fragments into their proper place (text.split is being used). I want to be able to have a click button event that then reads the second line and replaces the first line's sentence with its own. Click the button again, it goes to the third line.
This is what I've created. It reads the first line (But honestly, I think it reads the entire thing and the first line is the only thing that can fit in the selected spots). It then splits the first line into fragments, moving them to certain areas of the form. Question goes to the Question label, answers go to the selected button.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim textParser As New TextBox

So, like I said, what would make it possible for me to create a button event that when I click on it, it moves to the next line in the txt file?

View 4 RepliesCharting - Plot Data Using The First Value
Nov 29, 2011I have been learning and developing a software using VB for my company. I seem to have some issues with Chart function. [Code] Those 2 points will plot 2 datas (xval, finvall) & (xval, finvall2). Here is the thing. When I do the plotting, the starting points are always at (0, 0). That points come from the data point collector editor in the series properties. The question is: How do I plot data using the first value that I have? I don't want to start at (0, 0) but instead using (xval, finvall) & (xval, finvall2). I can't change the data point at run time. Many thanks!

Zedgraph - Y2 Axis Curves Won't Plot
Jul 25, 2010I have followed a tutorial from Zedgraph's wiki but I still seem to be having issues. When I run the code below, only the 3 curves on the Y Axis plot. I know the datasource is correct from which the 4 curves on the second Y axis are being created, because I have checked the table after creation. For some reason, however, the curves do not show up and the Y2 Axis does not change its scale to reflect any new curves. Does anyone see what I'm missing here?

Generate A Real Time 2D Plot With Autoscaling?
Oct 27, 2010I have finally made the switch VB.net and I am using VS2010 .NET 4.0 with WinForms. I want to generate a real time 2D plot with autoscaling and update the graphics/picturebox/form/<insert control here> from another thread so when I click a menu the device doesn't halt. The graphics are intensive in that a function is continually reading from hardware and drawing the data. I have been able to do this in VB6 (minus the multithreading) with GDI API and it ran great. Now in VB.NET GDI+ is used which is extremely slow. So my questions are as follows:
1) Should I go back to GDI commands or will this be outdated soon.
2) Should I use Direct2D, if so do I need to switch to WPF and are there any WinForm examples
3) Best approach to multithread this, if I double buffer can I have the GUI thread periodically read the buffer and display it. How can I tell the drawing thread to post an update and the UI thread displays it when it has the chance, similar to using InvalidateRect()
