Im trying to fill my DataGridView with data where the Column "RefID" is equal to the tbRefID.text that is on the same form but its not working my code is as follows.
Public Sub New(ByVal lviQ As ListViewItem)
InitializeComponent()
Me.tbRef.Text = lviQ.SubItems(0).Text
[code]....
and the code for the FillByRef is
SELECT RefId, QuTask, QuCost
FROM quote_tasks
WHERE (RefId = 'tbRef.text')

I finally got this code to work after hours of toiling:
[Code]...
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.

I finally got this code to work:
vb
Dim path As String = OpenFileDialog1.FileName
Dim myDataset As New DataSet()
Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""")
Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.Fill(myDataset)
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
So replace:
vb
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text
Next

Here i have code filling a drop down box with the company name.
Private Sub Filllistcomp()
listcomp.Items.Clear()
'define select statement
[CODE]...
This part works. The drop down menu is filled with all the company names. The following part does not work how ever.
Protected Sub listcomp_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles listcomp.SelectedIndexChanged
'create the select statment that serches for a record
[CODE]...
There is no error thrown either. The information is just not showing up.

I have a small 10px by 10px image, and I want to use VB.NET to find out if that image is (an exact) part of a larger image.I thought a method of doing this would be to lock the bits of the larger image into memory and then loop through each pixel in the image and for each pixel, I could take the 10px by 10px section which is down and to the right of that pixel.. and then compare it to my smaller image.
This is the code I have so far:
'Lockbits of larger image to memory
Dim bmp As New Bitmap(Image.FromFile(System.AppDomain.CurrentDomain.BaseDirectory() & "picture.bmp"))
Dim pxF As PixelFormat = PixelFormat.Format24bppRgb
[code]....
when I'm looping through the 10 by 10 section and I find the R G B bytes for each pixel, how do I store this in my rawImage array so I can convert it to a back bitmap and compare it with my original small 10by10 image?

I wish to extract numerical data from a text file and plot the data on a graph using the Zengraph classes. Each record has five variables.
I attempted to use the split function but failed to successfully get past one record.
1) How does one create an array or arrays using a text file containing many records, each with five distinct variables?
2) Is it better to create a number of single-dimension arrays or create one multi-dimensional array?
3) Is it easier to somehow convert a text file to an Excel file, with each variable in its own cell and each record on one row?

Basically iv got a form, and the fields are
"Full Name":
"Amount Contributed in �":
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith
Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:
Public Class Form2
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
