Dots More Dense At Upper Or Lower Edge Of Curve (searching Algorithm)?
Mar 2, 2011This question may be off-topic. If it should be posted in another place (even on another board) For some given curves (see sample below) I have to quantify whether the red dots in some regions of the curve are more dense at the upper or lower edge of the curve. Which algorithm might be adequate to perform this task? The curves are constructed from measurements. (No mathematical formula behind it.) Every data point has two dimensions: A value in the range 4000-7000 and a second value 0-255.

View 11 RepliesDraw Control Past Edge Of Form?
Feb 24, 2010I've got a usercontrol that's a simple rectangle with three labels on it. It's essentially triggered to give a caption to an image when the mouse is moved over it. As I feared, adding the control to the form (or any container on the form) restricts drawing the control to the region defined by the container. I tried increasing the region of the form and the container, but it still didn't draw outside the container.
So my question is: Is there a way to make the control display partially inside the container/form and partially outside it, or is there a better object type that will do what I want?

Custom Control Losing Size Around Edge When Added To Form
Dec 7, 2011Having some issues with creating a simple control in vb.net.
I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)
When i then build it and add this control to a form. Some of the edges are cut off and it isn't anchored the way it was in the control.[url]...
as you can see in the second image the control has lost its white border at the right and bottom.

Oct 17, 2011I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.

Run A User Control Sub After Container Has Initialized User Control Properties?

Access User Control Attributes From A User Control?
Mar 27, 2009I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.

View 4 RepliesCurve Fitting Through A Collection Of Points?
Jun 23, 2011I'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.
Grade Analysis And Curve Calculator?
Dec 19, 2011Write 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?
View 1 RepliesGraph A Curve Of A Function In A VB Form?
Jul 9, 2009How hard would it be to graph a curve of a function in a VB form.
Attached is a graph from excel which is exactly what I need to do.
I have the function of some fluid properties and I'd like to choose a min and max temp then have the function graphed, with temp as the x and the fluid property as the y which would auto scale to fit the curve.
Actually now the program i have to return the properties at one temp is just a GUI front end to call a fortran program to return the properties so actually if I just use that it'd be graphing points and not directly from the function. I can always make it completely VB based if graphing from a function is easier than points. It'd be a slight pain to rewrite all the code for the functions though.

View 1 RepliesVS 2008 How To Calc Curve Points
Jul 26, 2010The 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.

View 3 RepliesSoft Edge Wipe Using GDI
Jun 18, 2009I'm trying to draw some text using GDI (i.e. using a graphics object). It is done using the basic method of creating a path, adding a string to it and using a brush to fill it.
The only tricky part is that I need to apply a soft edge wipe to it. To describe what I'm trying to do better, I've uploaded an example done in photoshop: [URL]
What is the best way of achieving this? I need to be able to control the mask that is creating the soft edge - i.e. the position of the gradient, the width of the gradient etc.
Ideally I'd like to do it using the graphics object and not dipping into .dlls - but at the end of the day I'll do whatever it takes!!
