Im drawing a chart based on values from a database as an image in a picturebox. I can then add lines and circles etc in the picturebox, so as to highlight areas in the chart.
The next step I would like to do is to have temporary lines and circles, so when I move the mouse, the circle grows or shrinks and only when I release the mousebutton the circle is assigned to the chart picturebox.
I would like to draw a rectangle on a form, for example to mimic a steel beam that is 6 metres long.Within this rectangle, there may be 4 "openings" or circles that mimic a diameter of 600mm, so i need to draw 4 circles within the rectangle, to indicate a beam that has 4 openings. Other issues I need to cater for is that one of the circles may not be in the centre, it may be slightly raised.The user can change the length of the beam and the size of the openings so i'd like to refresh my drawing to keep in line with this.

I've got a fun little question for you all. I am designing a program that allows you to click on a picture to input data in certain areas. What I want to do it pretty allow someone to take a look at a picture. Click the add point tool, then select an area on the picture where it places a circle. I then want them to be able to go back to the circle and modify data if necessary

I would like to build a line chart which can redraw or change during a period of time with dynamic data. So that the x, y axis will change if out of range. The graph may be somehow similar to Matlab. I am using vs2005.
View 2 RepliesSo I have been working on some code that is a supplement to a video game that I play (doesn't really give me an advantage, I'm against cheating) as recreational programming to get me to learn more things which apparently is working immensely.The video game is called DoTA which is a custom map in Warcraft 3.
What I am trying to do is to make a program that can manually click the skills when the user presses the key they bound to that skill. This allows for more precise skill usage as keybindings in the game change randomly which causes chaos.
I first tried using mouse_event to move, click down, click up, return back to original location. This worked, but I ran into a problem that occurred if mouse movement by the user was happening while the code was being ran. The problem mainly would cause the mouse to move off the skill before clicking or even after the mouse down event.
So then I looked into SendMessage and PostMessage but it took a while before I could fully grasp everything about the functions mostly due to many examples posted online being different from one another as far as the declarations.
I now have matched the output that happens according to Spy++ when I actually click the mouse myself with various PostMessage and SendMessages, but am still having an odd problem:
I provide the coordinates to click on say Button 1. Spy++ tells me it is clicking it properly, but I do not actually get a click. However, if I manually move my mouse over that button, even on the very corners of it, and then press the key, it clicks it (although it also seems to work on one other button in the game.) Other than that, it will not click any other button besides the one that the coordinates are over.The game does not have any child windows so it doesn't seem like I can get the handle of the actual buttons themselves.Here is what I have as test coding to figure this all out (the sleep time in between mdown and mup is because the game doesn't register if clicked too fast):
Option Explicit On
Imports System.Runtime.InteropServices 'MarshalAs, Marshal
'Imports System.Reflection 'assembly
[code]....
I was thinking that if there was a way to maybe pause control from being able to move the mouse that I could just revert back to the original mouse_event code as well, but I haven't found anything that can take away control like that (actually, I wouldn't even want that posted TBH as it could be used for malicious stuff).
EDIT:The code at the bottom is just stuff I was using to match what happens when I actually click according to Spy++.
I have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?
View 1 RepliesI am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
Private Sub mainForm_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click
Dim penColor As New Pen(Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255, Rnd() * 255), 2)
[Code]......
This works to do what I need to get done, I just need each circle to have a random color as it is drawn.
The purpose of this (maybe there is a better method I don't know) is to so the user can say what order they want pieces of code to be compiled in. Sort of like a flow-chart. I want it somewhat animated, so, example being 3D circles the user drags and drops in the order they want things.
1. I need 4 circles inside of a form.
2. I need it so when the user selects the circle, they can drag and drop it in an order.
3. User clicks OK to finish their chosen order.
I haven't designed anything before that needed to check the borders of the form etc.

View 5 RepliesRight now I'm trying to make collide a lot of circles drawn during runtime. I have no problem making 1 circle collide with the form's bounds nor with another circle, however, if I draw like 25 circles in runtime, how can I make each one "move" and set the "collision properties"?
Can I make the circles move outside of the form? Let's say, the whole screen?
I am struggling with coding up a bit of logic.
I have a map which I have created zones which are basically rectangles which have the coordinates sorted
eg
Zone 1
Zone 2
Zone 3
I then want to create circles within the rectangles. So for example
Item1, Zone1
Item2, Zone1
Item3, Zone3
Item4, Zone2
Item5, Zone1
So i would like Item 1, 2 and 5 to show up as three circles and when the mouse cursor floats over them to show it. The item list is dynamic and so I am not sure how to get about with this?
How do I dynamically add or remove a chart series on a WinForm. To date all my MS Charting experience has been dealing with ASP.Net charts with static sql select statment to a SQL Database. In the new project that I have been assigned I have different cities with different amounts of points that they want monitored. One city might have 3 an another might have 5 or 7 so I can't hard code the amount of series that I need. It needs to be set up so the amount of series can be flexible depending on the city selected and then display those points on the chart.

For the project I have to include some graphs however I've no budget (surprise, surprise) to purchase 3rd party controls & the graph controls within .NET v3.5 dont have that elusive "wow" factor that I'm looking for.
The chart controls in .NET v4 (MS version of the Dundas controls) are just what I'm looking for but I unfortunately cant use them as the 3rd party API won't work in v4 & there are no plans to have it upgraded to v4 compatable anytime soon

Basically, the user will input a "product" into a textbox and upon a button click, will be transferred to a listbox. The problem that I have is that I need to also collect a precentage for each product, and using that percentage, create a type of bar chart with "x"s based on the percentage. The final outcome of the application should look something like this-

This is a problem like the puzzle - "find minimum number of coins to completely cover a piece of paper".
The difference is:
in my case RADIUS of the coins is variable (but all coins should have same radius).
Real scenario:
1. I need to draw circular shapes on a rectangular image.
2. Number of circles (N) is CONSTANT/ User input
3. Size of image (S) is CONSTANT/ User input
4. The program should find the MINIMUM RADIUS (R) that is needed to draw N number of circles on an image of size S, so that, the image is completely hidden behind the circles.
This is NOT a puzzle/assignment that I'm trying to solve.This is part of a larger project that I'm working on.
I don't need any drawing code. I just need the code/algo to find the radius.
Question: I need to draw pictures as below in C#/VB.NET Draw ishihara-transformations (circles in circle without intersection)?
Note that my problem is NOT drawing circles in C#.
My problems is drawing them without much whitespace and without intersection.
My thought would be using "Orbits" and then draw the circles with center on the "orbit" lines. (with some orbit lines for bigger and some only for smaller circles)

I would like to enquire how I would go about population a chart (bar graph) in VB 2010 Professional?
I am pulling the information from a MS SQL Database.
I would like to copy a chart to another form. I have a MainForm which displays several charts. However I have another form which I would like to copy some of the graphs from MainForm to this new form (GraphCompare) so that the charts can be compared easily by the user. I am unsure on how to do the actual copying part.
so far I have this:
Dim Chart56 As New Chart
Chart56 = Chart1
GraphCompare.Panel1.Controls.Add(Chart56)
