Create A Graph Where The User Can Input Data Into Textboxes And Then Plot The Data?
Jun 15, 2009
I'm just trying to create a graph where the user can input data into textboxes and then plot the data. I am attempting to use Zedgraph, but open to other suggestions. The program below creates a plot, but it won't update when the textboxes are updated.
Imports ZedGraph
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code]....

I'm currently trying to use ZedGraph to plot a graph based on some data I have extracted from a machine, with reference to a user entered "Frequency" range. I has to be a line graph, with Frequency on the X-axis, and extracted data on the Y-axis. There are 4 channels for the machine, but all data values extracted are close to each other, so multiple Y-axes are not needed. I'm also trying to do it within a class, and the graph should only be drawn when I click "Button3", otherwise there would be no data anyway and button2 extracts the data.
Below are my class (the graph code is at the bottom) and form1, which button3 should call the class, but I'm stuck for both the button interfacing and the class writing. I have also attached the output I get so you can have a look at what I need. Open it in Excel to see the format. The whole program is also attached as a text file if you prefer it that way.

I am trying to save new data every time and then I have to edit it or load it. here is a screenshot you might get some idea by looking at this:
First I will input data (in all textboxes) using create button which will be stored then If I want to edit any thing I will input only the part number and press search. the stored data will come up. I will edit it and update it (Load button is update). Now I can save it in txt file and load it using regex but the problem is edit. I can not edit. If i create a database I cannot save 100 parts (or may be more) in one database so it might create too many db files. So is there any other option I can save parts detail then load it and edit it without create so many dbs?

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.

I have a directory containing list of files.
Those files have some list of values as x and y ordered as line by line.
And my question is just I would like to read those files one by one and to plot line graphs based on those values.

ive been struggling on this portion of my code for almost 3 days with no luck. i have a database containing a list of transactions (in this case, the product name, quantity and date of sale). I want to plot a graph for each product showing the amount sold each month for the past 12 months. The functions to calculate these values are working fine. but my problem is this:
each tab page is named after the product name:
TabControl_SaleOfProducts.TabPages.Add(
"TabPage_"
& ProductName, Item)
and then to this tab page i want to add the graph. but i cannot reference the newly created tab page?

I need to be able to take an MP3 or WAV file and plot a graph of its waveform over time. Prefferably without playing it first. The representation doesn't have to be amazingly accurate as it's not for EQ purposes. I just need to pinpoint certain points in the MP3 / WAV when specific music / sounds etc occur (similar to the display in Windows Sound Recorder).
how I can go about that, or if it's even possible in VB 2005?

How do I determin if a user has given me what I am asking for in terms of data type.
Example if my prompt to the user say "Give me a number of double data type"
How can I tell that the user entered a double xx.yy?
Or if I am testing for integers and I get user input ABC.GH?
I know about CDbl and CInt and CStr but these don't work unless data is provided. Also how do you test if the conversion took place? Also how do you differencate between 12.00 being integer?

I'm trying to make a program where user can input data from a textbox into an array and when the user hit the enter key, it compare it to a data grab from a text file. Here is my code so far:
Private Sub TextBox_KeyDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox.TextChanged
Dim input As String
[Code]....
I got the part where the program can graph data from text file and put it into an array called "varia3". The part I could not get is allowing user to enter data into the textbox. When I run the program, the sec I try to enter a letter or number into the textbox the program ended.

So I'm developing a Windows Forms Application in Visual Basic 2010. The user searches for data and fetches results, updates fields and some other CRUD operations. I want to provide a user input validation. Usual stuff i.e. some fields need to be always numbers>0, others need to be non-empty in order to avoid Null access on some objects and others just need to be some fixed strings.

I have been learning and developing a software using VB for my company. I seem to have some issues with Chart function. [Code] Those 2 points will plot 2 datas (xval, finvall) & (xval, finvall2). Here is the thing. When I do the plotting, the starting points are always at (0, 0). That points come from the data point collector editor in the series properties. The question is: How do I plot data using the first value that I have? I don't want to start at (0, 0) but instead using (xval, finvall) & (xval, finvall2). I can't change the data point at run time. Many thanks!

It's been a good few years since I dabbled in VB and I'm very very rusty so any help would be great! What I'm looking to do is search an access database with user input and display the relevant record.I have a single table set up in an access database called school_info with the following fields and data:
Tres________DfE________Name_________Type
001________1234________School 1________Primary
002________4321________School 2________Secondary
[code]...
I've linked the database to my new project, connected the database and added the 4 fields to my form. When I run it, the data shows in the boxes fine.The Tres and DfE fields are show in text boxes on the VB form, and the school and Type are show in labels. What I really want to do is be able to manually type in either a Tres or DfE number into the relevant text field and have the other labels auto populate with the relevant data that's stored in the database table.

So far i have a really basic form application that allows a user to enter some information and does a small calculation, displaying all of the information gathered on the final form.
Im looking to try to save this information but have no idea where to start,im trying to just take whatever is in my text field and put it in a table row. I created a one table database in Access and linked it to the form with a button to try and save it.
I thought it would be as simple as tablename.rowname = textbox.text or something but apparently not and all ive ended up with so far is this:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Me.Validate()
Me.TblCustomerBindingSource.EndEdit()
Me.TblCustomertableadaptor.Update(Me.DatabaseDataSet.tblCustomer)
End Sub
I dont even think im close, ive just been fiddling with the predefined code in Visual Studio, trying import ect but the button just doesnt seem to do anything.
