View 1 RepliesSignal (NOT Cancel) A BackgroundWorker?
Mar 7, 2011Is it possible to send information to a BackgroundWorker thread while it is running? Here is my scenario: Parent thread calls background thread to send a data request to a database. If it's a big complicated query it can take a while for the db to respond, so putting the db request on the background worker thread is great. My app can do other stuff while the one thread waits for the db.
Now, db responds with beginning of data. I want my background thread to report back meta data about the result set to the parent thread. No problem there, I can use a custom user state object and the ReportProgress method. But now, how to I send a signal from the parent thread back to the worker thread? I want the background thread to wait while the parent thread does something, and then tells the worker thread to keep going or quit. I know how to cancel a background thread, but I want the parent to be able tell the child some information other than "cancel". Here's one way to think about it:

Build An Oscilloscope And Display The Signal As On And Off (square Wave) From The Encode?
Feb 26, 2010I am trying to build an oscilloscope; I will be using a signal coming from digital encoder going through MAX232 logic level converter to the PC via the serial port 1. The signal from the encoder is 3VDC when it is high and 0VDC when it is low, the encoder resolution is 1024 PPR, the encoder is attached to motor (1800 RPM) so the max resolution is 1843200 pulses per minute or 30720 pulses per second. I would like to make my form display the changing of the input from the serialport1 to graphical display just like the digital oscilloscope. I
I want to be able to display the signal as on and off (square wave) from the encoder and be able to display the signal as speed so when the motor is running at full speed the line be at the top of the graph and when the motor drop to 20% of its full speed the line will drop to 20% and so on.

View 2 RepliesCapture Raw Signal From WiFi Card As Would A Sound Card
May 9, 2012Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.
