Dynamic Graph In .net?

Mar 1, 2012

i 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.

Dynamic SQL To Dynamic LINQ In .NET With MS SQL Server 2008?

May 24, 2010

I need to represent the following query using LINQ:

DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0

[code]....

Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.

VS 2008 Dynamic Timer In A Dynamic Form

Feb 19, 2010

Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)

1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.

2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.

I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)

Heres my code;

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form

[Code]....

*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)

Dynamic ContextMenuStrips On A Dynamic Form?

Oct 15, 2009

I have a form that i need to be 100% Dynamic. So it could contain 10 labels maybe 100 who knows.

When you hover over a label there will be a different contextmenustrip to appear for each and every label. So all the contextmenustrips are Dynamic and contain 1 option maybe 2 options even 3 or 4 up to the users settings.

My problem is not creating a handler for when the user clicks on the contextmenustrips options. The problem is knowing which one of the options for that contextmenu was clicked!!

Dynamic ToolTip For Dynamic Text Box?

Jan 11, 2012

OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.

On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.

I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"

Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()
Me.Controls.Add(t_0300)

[Code].....

Plotting 2d Graph In C#.net?

Jan 19, 2011

I was writing a program on a web form which is reading a file and then plot the file as a 2d graph.

the file looks like

c1
number1
number2

[Code].....

where c1 c2and c3 is the header which the readfile stream should ignore and the total "number" numbers are decided by the user which can be a variable.

the graph will take the c1,c2,c3values as x-axis and the number values as y-axis.

how can I draw the graph from reading this file? can some one kind enough to show me some code?

Application - Plotting X/Y Graph ?

May 4, 2009

I wanted to plot a graph for one of my application in VB.net. I want a Time (X-axis) Vs Temperature (Y-axis) graph, where:

1. X- Axis has vertical lines every 10 minutes. So there are 6 vertical lines between 1 hr. The labels on the Axis should be written at every hour even though the vertical lines are at every 10 minutes. (Eg: 10:00, 11:00, 12:00, 13:00, 14:00...)

2. Y-Axis should have horizontal lines every 10 degrees C. So there are 10 Horizontal lines between 100 degrees. The labels on the axis should be written at every 100 degrees (Eg: 0 deg C, 100, 200, 300...)

Clear And Redraw A Graph?

Apr 1, 2011

I am writing a VB program that measures the voltage on a circuit and then graphs the voltage value. I read what the voltage is at ever milisecond and load that value into an array and shift all the data one to the right. On each timer tick i regraph the data.

The problem i am having is on each tick i erase the picturebox then i redraw the graph using the new array. Because of this the further out the line is from the start of the drawing processes the less it shows the line. You get a flicker effect. I have been seeing if there are ways to remove the flicker but the few things i have found have to deal with doublebuffered but i do not think that is the issue here. I think i need to find some other way to clear the picturebox.[code]...

Convert Program 6 Graph To NET?

I'd like to convert it to .NET, but I'm not really sure how to do it. Expecially the Polygon API is giving me headaches. I guess I can use DrawPolygon, but I'm having problems with the second parameter (converting Pts to System.Drawing.Point) and also the third parameter that DrawPolygon doesn't have. I'm not looking for anything fancy like the chart control, but like to get the graph as shown in the image below.[code]....

Create The Bar Graph With Each Store's Name?

Oct 14, 2011

I'm having trouble figuring out the logic to this problem:Thus, you can create the bar graph with each store's name, and a separate label that has the sales information for each store. Since each asterisk represents $100 sales, you can just do # of sales mod 100 to get the number of asterisks you need for that store, then loop and add asterisks until the label has the correct number of asterisks. Repeat for each store input that the user gives.
