You will need to convert the logic-level (5 volt) signals from the microcontroller into the RS-232 level signals that the computer requires. See this article about the very useful MAX232 chip: http://en.wikibooks.org/wiki/Serial_Programming/MAX232_Driver_Receiver[^]

I'd assumed you'd need something more like: http://cmm.ensmp.fr/~beucher/prom_sta.html[^] As you can see the lanes on the road form "Trapezoids" which can be detected, this doesn't help you, as you have a very different problem. sebogawa wrote: I just think distancing and angling every white point on the image would be very time consuming processing wise. Yes, but complicated tasks such as these are heavy-duty! One thing that strikes me immediately is that you should look at your camera/image resolution, it doesn't need to be very high and this will drastically cut down your processing costs. Assuming the surface is flatish and the camera is at a constant height and angle, you can calculate the distance of every pixel in the image when the rig is calibrated (i.e. once) as each will always appear at the same distance due to the geometry being constant. Again, at calibration, you then create an ordered (by distance) dictionary of pixel co-ordinates. When you start in earnest it is just a matter of rattling through the image to find the nearest white pixel. Triaging the areas in the image into "Don't worry- too far away", "need to start planning", "urgent" could again reduce your costs. Things that could complicate this are a) obstacles being mistaken for lines (if they are white) b) The robot heading off in the wrong direction!

Hey sorry I didn't even know that is a bad thing. I just saw a question and offered to help.

Nothing really. That is exactly why I've used parentheses. Now if I had be sure, I could have left out again entirely. :laugh: Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles] I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

Hi, you could save settings to disk by creating a loop, similar to the foreach I have shown; and later reload just like you load the first time. PS: replying to yourself, I did not get a notification and saw your message only by accident. :) Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles] I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

Personally, I prefer to store such files within the database.

Thanks again you have all been great help...Once I'm done I will post my work on the site, if its good enough. I'm sure someone somewhere will be interested in underwater ultrasonic communications. : )

I guess you need to check if the name is already in the list, and if so, append a number to the name. In that instance, I am assuming you need to add the FilterInfo to the combo box, and set the DisplayMember to be the Name property, otherwise, how do you tell which is which, if not by name ?

I have just created a test project and pasted your code into it. It works perfectly. So, question. What event are you handling with freezeFrame_MouseClick? You see I tried it with both MouseClick and MouseDown of the PictureBox, and it worked for both. Henry Minute Do not read medical books!

Hi, several comments: 1. sebogawa wrote: txtMouseX.Text = e.X.ToString(); int mouseX = int.Parse(txtMouseX.Text); What a waste. You already have e.X as a number, why do you need to parse a string then. Just write int mouseX = e.X; txtMouseX.Text = mouseX.ToString(); 2. Bitmap refImage = new Bitmap(freezeFrame.Image); You claim the problem is here, I doubt that. There are two ways this could fail: a) freezeFrame.Image being null would result in a NullReferenceException b) freezeFrame.Image being of some special ImageFormat (such as EMF) might cause problems, I'm not sure though. 3. Color currentPixel = (refImage.GetPixel(mouseX, mouseY)); would throw an ArgumentOutOfRangeException when mouseX and/or mouseY fall outside the image. 4. redMinUpDown.Value = currentPixel.R - rangeLimit; may cause problems since the lowest achievable value is negative (-rangeLimit). If Value is set outside [Minimum,Maximum] an ArgumentOutOfRangeException will be thrown. Overall, your code is low-quality as it lacks a lot of checks. :) Luc Pattyn [Forum Guidelines] [My Articles] Avoiding unwanted divs (as in "articles needing approval") with the help of this FireFox add-in

Thank you for the help Henry. I was wondering if the videosourcePlayer_NewFrame can inherit the videoSourcePlayer_MouseClick values and apply them to the _NewFrame block? I have been playing around with basic inheritance but involves only classes. I stunbled upon a C# lesson involving polymorphism (inheriting from a method) at the following link: http://www.softsteel.co.uk/tutorials/cSharp/lesson14.html[^] Do you think this will help? If not then how can i solve my problem, detaching the greyimage declaration and applying it to mouse click does nothing due to the fact that the greyImage can not be changed. I am trying to make it so that when i click on the live video feed control, it takes the ARGB values of the pixel clicked on (plus or minus 30) and apply it to the ARGB filter textboxes which saturates the image to only show the given color. (color tracking) the purpose of this app is for a robot that i am working on that tracks while traffic lines, 3 inches thick which the robot must stay in between. I am using webcams, and the AForge library for video processing and I scrapped together pieces of the "Lego Pan and Tilt App" from a Code Project Article. The app works but i have to manually set all the ARGB ranges to find the color i want. It would be easier to just click on the image and get the values. I hope this information helps, im stuck and at a loss for ideas. Any help would be greatly appreciated. :-D modified on Tuesday, April 21, 2009 3:11 PM

If it is, then in the designer, select it, in the Properties Window, switch to Events page and double click on the MouseMove event. Put your code in the handler stub created in the code view for the form, should work OK, no need for offsets etc.. Henry Minute Do not read medical books!
