View 1 RepliesI have a program written in VB6/VB.net and its supposed to calculate a set of numbers based on user input. From there the data is saved into an xml file. I want to be able to take the data from the xml file and draw a chart representing all the data. I found a tutorial that draws line graphs based on an predetermined array of data, but I need the program to take the data from an xml file.
Heres the code for the line drawing program:
Option Strict On
Imports System.Drawing.Drawing2D
Public Class ViewChart

I have created a function to create a string to populate a y axis with data:
Function talktosql() As Double
Dim ConnString As String = "Data Source=MARK-WORKMSSMLBIZ;Initial Catalog=Yahoo_data;Integrated Security=True"
Dim SQLString As String = "SELECT [RDSA.L] FROM yahoo_data.dbo.XLON"
Dim SqlDataAdapter1 As New SqlDataAdapter(SQLString, ConnString)
[code]....
so it should for example come out like this:
Dim yValues As Double() = {55.62, 45.54, 73.45, 9.73, 88.42, 45.9, 63.6, 85.1, 67.2, 23.6}
I cannot seem to get the data from the function into the right format to populate "yvalues".(the msgbox that I put in at the end in the first code renders the result "0")
I want when Push Button data from Excel(The next cell data) go to the next Line in Textbox.

I am wondering how one would go about using the graph control to display a bar graph that shows trends from my database.They are rather easy trends. I am building an industrial issue tracker and I would like for it to show how many issues were submitted each month for the last 6 months and also how many issues in the last month were of certain types that are categorized in my database.
View 1 RepliesYpos = TopMargin + Count * PrintFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())
Count = Count + CInt(ROData(x, 4))
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.
I am trying to click on certain rows in a datagridview and have the information in the rows sent to a textbox. It does not append each row to the textbox though, which is what I want it to do. it just replaces it with the row I click on. What's wrong with my code. I have tried cell click too.

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.

View 1 RepliesCurrently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.
