Open EXCEL file with VB6 and read the content

I was planning to write an application today which simply opens an Excel file and read the Cell values into an array so that I could manipulate it accordingly. Since I don't have VS.NET installed on my home PC, I decided to do it with VB6 :o)

Here is the code...

Private Sub cmdOpenExcel_Click()
On Error GoTo ErrHandler
    Dim xlsApp As Object
    Dim xlsWB1 As Object
    'Late binding to open an XLS file which is present on my local harddisk
    Set xlsApp = CreateObject("Excel.Application")
    xlsApp.Visible = True
    Set xlsWB1 = xlsApp.Workbooks.Open(strFileName)
    Exit Sub
    MsgBox "There is a problem while opening the xls document. " & _
    " Please ensure it is present!", vbCritical, "Error"
End Sub

Now, since I know that my Excel file (which I want to work with) has 15 columns and 200 rows, here is what I did to read all the content to an Array for further manipulation.

Private Sub cmdParse_Click()
On Error GoTo ErrHandler:
    Dim xlsApp As Object
    Dim xlsWB1 As Object
    Dim xlsWS1 As Object
    'Opening the file to parse now
    Set xlsApp = CreateObject("Excel.Application")
    xlsApp.Visible = False
    Set xlsWB1 = xlsApp.Workbooks.Open(strFileName)
    Set xlsWS1 = xlsWB1.Worksheets("Sheet1")
    Dim col As Integer
    Dim row As Integer
    Dim str As String
    str = ""
    MaxRow = 200
    MaxCol = 15
    'Declaring an array so that we don't have to depend on the excel file anymore
    ReDim CaseArray(MaxRow, MaxCol)
    'Reading the Excel file and putting everything in Memory for faster manipulation
    For row = 1 To MaxRow
        For col = 1 To MaxCol
            CaseArray(row, col) = xlsWS1.cells(row, col).Value
    Set xlsApp = Nothing
    Set xlsWB1 = Nothing
    Set xlsWS1 = Nothing
    Exit Sub   
    MsgBox "An unknown error occurred while Parsing the Excel. Sorry about that!!" , vbCritical, "Error"
End Sub

In my case, CaseArray was a 2 dimensional Array using which I used in the other modules to manipulate the data as per my requirements!

Hope that helps!
