VB program get data directly from Excel spreadsheet

How can I get VB to get data directly from an Excel spreadsheet?  Right now, I'm converting the Excel file to CSV, then making it a text file, then using INPUT AS to get it into the VB program.

There's gotta be a way to do this directly, with no conversions needed, but how?  (Note I'm using VB 5.0 Pro)

You can use ole objects to open the workbook and then you can reference the cells directly.
Or.

You can access excel just like you would a database.  here's an article on that:
http://support.microsoft.com/default.aspx?kbid=190195

I'll try to find some reference material for you on the ole objects.  Till then, look up automation in your help files.

I'm back.

Here's an example of late binding.  This function gets the data located in A1 of Sheet1

Function getXLData()
Dim xl, wb, ws
Dim theResult As String

Set xl = CreateObject("EXCEL.Application")
Set wb = xl.Workbooks.Open("C:\Your\Path\Your\Workbook.xls")
Set ws = wb.Worksheets("Sheet1")

With ws
    .Activate
    theResult = Range("A1")
End With

wb.Close
xl.Quit

Set xl = Nothing

MsgBox theResult
End Function

The function inputs one value.  I need to input many columns and rows worth of data, and store the data into arrays.  For instance column 1 becomes the array LastName(i) and column 2 becomes FirstName(i).  How do you implement this?  I'm new to VB, and there's nothing like this in older versions of Basic to help me.

dds-
When I try the code you sent, I get an error message since VB thinks range("A1") is an array and it's not dimensioned.  How should this code read?

It's still not working.  I'm trying to read in a bunch of cells into an array in VB.  What's wrong???  Thanks.

Private Sub Form_Load()
Call getXLData
Show.Form
End Sub

Function getXLData()
Dim xl, wb, ws
Dim LastName(4), junk As String

Set xl = CreateObject("EXCEL.Application")
Set wb = xl.Workbooks.Open("C:\Basic\labels.xls")
Set ws = wb.Worksheets("Sheet1")

With ws
    .Activate
    For i = 1 To 2
        junk = "a" + Str(i)
        LastName(i) = Range("junk")
        Print "lastname(i)="; LastName(i)
    Next i
End With

wb.Close
xl.Quit

Set xl = Nothing

MsgBox LastName(1)
MsgBox LastName(2)
End Function

two things:

change this line:
junk = "a" + Str(i)

to this:

junk = "a" + Trim(Str(i))

then change this line:
LastName(i) = Range("junk")
to this:
LastName(i) = Range(junk)

That should do it.

I get an error message for Range(junk).  VB complains that Range is a sub or function that is not defined.  Revised code appears below.  What should I fix now???

*******
Private Sub Form_Load()
Call getXLData
Rem Show.Form
End Sub

Function getXLData()
Dim xl, wb, ws
Dim LastName(4), junk As String

Set xl = CreateObject("EXCEL.Application")
Set wb = xl.Workbooks.Open("C:\Basic\labels.xls")
Set ws = wb.Worksheets("Sheet1")

With ws
    .Activate
    For i = 1 To 2
        junk = "a" + Trim(Str(i))
        LastName(i) = Range(junk)
        Print "lastname(i)="; LastName(i)
    Next i
End With

wb.Close
xl.Quit

Set xl = Nothing

MsgBox LastName(1)
MsgBox LastName(2)
End Function

Sorry again for being away so long.  This one is simple.  Since you are using late binding to reference Excel, you need to precede any of Excels functions (i.e. Range) with your reference to Excel.  In this case, just change the line to read:

LastName(i) = xl.Range(junk)

Hope that helps.
