Thanks, but since the printer is not a POS device, this is not going to work.
If there was a print utility that could be called from VB.NET, that would suffice, if there is no way to send text directly to a printer driver in VB.NET.

So what?? I shows you how to print directly to the printer without going through all the GDI stuff to draw an image of the page.
Once you can get directly to the printer, you can send it all the commands you want that are native to that printer.

I am doing a bar chart using a date variable and a double variable. I am having trouble reading in the date. Do I have to read in the date using seperate variables for the date?

Hey
Post up a small snippet of code so we can see what is going wrong and trying to help you. By small I dont mean the entire code base but a simplified version of what is happening.
You could even try using a small simplified function or here is a crazy idead - test and debug the function (I have heard people do that sometimes).

I am doing an Example of creating barcharts in VB.
I am using two variables
Thedate as date = Today
Theweight as double
The weight is input on a daily basis via a textbox. The date is taken from the pc's calender. I have a sample to go by, which uses integers and doubles as variables. Everything i have tried so far gets errors because of the date.
Dim NumberGames As Integer
Dim DStreak(144) As Double
Private Sub frmPlot_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Streak As Integer
'Open file, load data in arrays
FileOpen(1, AppPath() + "mar95.csv", OpenMode.Input)
NumberGames = 0
Do Until EOF(1)
Input(1, NumberGames)
Input(1, Streak)
DStreak(NumberGames) = CDbl(Streak)
Loop
FileClose(1)
picPlot_Paint(Nothing, Nothing)
End Sub
The above code is what i am trying to follow.
i hope this helps
thanks

So where are you REALLY reading the date from?? I'm quite sure it's not a bar chart...
We'd need to see the code that you're using to read this data.

It would be better if you stopped using TXTSpeak in the forums. There's over a hundred keys on the keyboard in front of you. Use them.

Hi,
I have and Issue where one of my imported fields is being formatted in the datagrid view,
The code to import the file is thus:
If OpenFileDialog1.ShowDialog(Me) = DialogResult.OK Then<br />
Dim fi As New FileInfo(OpenFileDialog1.FileName)<br />
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Text;Data Source=" & fi.DirectoryName<br />
Dim objConn As New OleDbConnection(sConnectionString)<br />
objConn.Open()<br />
Dim objCmdSelect As New OleDbCommand("SELECT SupplierID, SupplierDebrand, RangeID, RangeDebrand, ItemID, ModelNumber, Description, cost, Usual, Sell, SKU FROM " & fi.Name, objConn)<br />
Dim objAdapter1 As New OleDbDataAdapter<br />
objAdapter1.SelectCommand = objCmdSelect<br />
Dim objDataset1 As New DataSet<br />
objAdapter1.Fill(objDataset1, "test")<br />
DataGridView1.DataSource = objDataset1.Tables(0).DefaultView<br />
objConn.Close()<br />
End If
But my problem is sometime I have a model number like "0802.123" but in the grid it is showing it as "802.123" So how do I stop it from formatting it as a number as opposed to text?
Thanks in advance

Hi,
You can set the custom format for that column.You can try using the following code snippet.
Me.DataGridView1.Columns(1).DefaultCellStyle.Format = "0##.00"
You will have to set the column index on the above code.

Thanks for that feedback, but unfortunatly it does not work, as the data is not always numeric sometimes it is text like "CAT 10" is there a .format that will force a text value?

You have to use a schema.ini file to describe each column in the file you're importing. That column is being interpreted as a numeric column instead of a text string.
