Will any of the free light-weight charting libraries; ZedGraph or NPlot, be able to draw a simple graph similar to attached image (no waste of space, and with colored plot areas)? This plot will act much like the task manager "CPU Usage" plots, with update of last value every 500ms, but only making a new datapoint every 1 minute or so.
Or is this so extremely simple that it's better to hard-code it? What classes should I look into for this?

View 3 RepliesI would like to know a simple method to create a simple line graph, with a grid and X and Y values... I tried just drawing in a picturebox but that was just annoying and not clear... Is there any simple way to create a little graph with prefixed values on X and Y (graph should just be lines drawns from different Y values, with always the same change of X)
View 4 RepliesI was just wondering if there are any examples around the internet on how to develop a simple CAD program.
Would I be better off drawing on the form directly or use a Panel or a PictureBox for that?

In short, I want to offer some kind of Expression feature to my users, unless it is too much work, as this project is not the most important one and I don't have like 2 years to develop it. I think that the better thing I should do is to write something like CustomExpression that could be passed in parameters to some functions or subs.
First I'd like to say I am not fluent in Visual Basic, I down loaded Express 2008 and have easily completed the first few lessons. I have some programing exerpience. I have written a few simple programs with Autolisp for Autocad.Vdraft will only integrate with full blown VB programs. So, Maybe someone can write a simple program using Vdraft api which can be found at :

View 5 Replies[URL]..I wrote a program with a timer set to tick every 100 ms. The values oscillate between 109 and 110 ms. Each tick, a variable adds +1 to itself; it starts at 0 and goes to 9 and then it goes back to 0 where it continues the addition process. When the timer ticks 110, the variables is added to a textbox. The pattern is something like this, which you can see in the above youtube video. 5 9 5 9 5 9 4 8 4 8 4 8 3 7 3 7 3 7 etc.

If rdbsideA.Checked = True Then
Do While AngleB > 0

Loop
MsgBox("The Length of Side A is ", SideA)

That is if the user seleects to find side a. When the messagebox pops up, it doesnt state the previous calculation, why is that?

I have a program with various settings, all stored in the app.config file. Often, I have a need to edit the connection string setting. I cannot do so using the My.Settings.myConnectionStringVariable method, as this is read-only. What I would like to do is have a big text box, and simply load the entire app.config file into it. The user could modify whatever they wanted, click save, and the program would save the new edits to the app.config file, and restart the program. I don't have a huge need to only pull out the connection string, as getting the text for the entire config file would suffice. However, if it is easier to pull out just the connection string from the config file, that would work too.
View 1 RepliesI'm currently trying to write a really simple game on which the player has to pursuit some figures on the screen. Since i'm just writing the prototype version i'm using a Panel wich i redraw 1000 times per second. Now, i want that every level is similar but not the same as past level, so i created a Level Class that contains the game objetcs of Player Class and the Figure Class, wich are the ones that have all the movement subrutines. So, with a Timer, 1000 times per second, i get the input from a joystick, pass it to the player objetc and update the position of the figure object. All this stuff is reported to an internal Panel that every level object has, wich i refresh and then pass it ByVal to the panel that the player actually sees. The problem i have is that after the first level ends, when the second level starts running, i can see the last frame of the fisrt level flashing behind the figures and it makes the game run a bit slower after every level. I tried keeping a copy of the inicial state of exterior panel and use it to clean the one i'm using on the levels but it didn't work...

View 1 Repliesi am to generate a line graph in vb.net. The graph should be something dynamic. I have a program calculating total distance, therefore in my output window i have iteration number and its corresponding value.
I have to plot the graph as iteration number by iteration value.I have tried an offline graph where i saved the values of the iterations and then draw the graph with the values.
But this is not what i am actually suppose to do. The graph should be generated simultaneously as the processing is being done. I am finding this a bit tough to do.
I have a CSV file in my working directory and dont know how to load in into a graph in VB. I already loaded my chart into the form and its called "Chart1" with "Series1".
