Introduction

“Might be a little bit heavy on the VB/ HTML side for old-time capacity planners...”

Vic Soder, CMG ERB

If you have ever written a COBOL program, you are overqualified for web development.

Application

MS ODBCProvider

ODBC

Circa 1990

Ubiquitous drivers

Not an Object-Oriented API

Relational bias

OLE DB

COM interface

Support for broader spectrum of data repositories

Interface used by ADO

ODBC data sources accessible via “MS OLE DB provider for ODBC” Possibly with reduced function

ADO

(currently) Highest level interface

Simplified object structure

Relies on OLE DB

RDS

Makes ADO data sources accessible across a network

HTTP, HTTPS, or DCOM

Uses Microsoft Internet Information Server as conduit

SAS ODBC vs. OLE DB

ODBC

Separate install

Full SQL support

Runs Proc OdbcServ instance

Field name is variable label

OLE DB

Auto install with V8

SQL not supported

Direct lib/member access

Field name is variable name

MSDFMAP.ini

RDS Security

C:\WinNT\System\MSDFMAP.ini

Create token to identify local data source for remote access

Determine permitted access

Other RDS/IIS Issues

IIS uses IWAM-servername as proxy (Launch IIS Process Account)

Pivot Table - OWC.PivotTableDSC - OWC.DataSourceControl

OWC Spreadsheet

Resembles Excel spreadsheet

Visible or not

Contains one or more Worksheets

Worksheets contain cells spreadsheet.worksheet.Cell(row,col) Single Worksheet then

spreadsheet.Cell(row,col)

OWC Spreadsheet Range

Identifies a rectangular group of cells

Used by methods that operate on groups of cells set Range = spreadsheet.Columns(x) object.Range(TopLeft : BottomRight)

OWC Spreadsheet API

ss.ActiveSheet.UsedRange.Clear

ss.ViewableRange = ss.ActiveSheet.UsedRange.Address

ExcelStyleCellReference = ss.Columns(Columns).Address

Set c = ss.ConstantsConstants available at run-time

OWC Spreadsheet Formatting

ss.TitleBar.Caption = “string"

ss.Columns.ColumnWidth = 100

ss.Rows(x).Font.Bold = True

range.NumberFormat = "hh:mm“

ss.Columns(x).Hidden = True

ss.DisplayRowHeaders = False

ss.ScreenUpdating = False

Populate Spreadsheetfrom RecordSet

Row = 1While Not rs.EOF Col = 1 While Col <= rs.Fields.Count ss.ActiveSheet.Cells(Row, Col).Value =

Populate Faster

OWC Chart

General purpose charting functions 45 chart types

ChartSpace - one or more charts

Careful with terminology Series – points to be plotted as a group Value axis is vertical (y) Category axis is horizontal (x)

Chart Types

OWC Chart API

Set cs.DataSource = ss.ObjectChart data will come from spreadsheet

Set chart = cs.Charts.Add()Add a chart to the chart space

cs.ClearClear all charts in the chart space

Set c = cs.ConstantsConstants available at run-time

OWC Chart - Formatting

chart.Type = c.chChartTypeLine Basic chart type – 46 varieties

chart.HasLegend = TrueChart will have legend

chart.HasTitle = TrueChart will have title

chart.Title.Caption = “C1”Take title from cell C1 in spreadsheet

OWC Chart - SetData

Method used to identify series1) Dimension or attribute of chart2) Data source3) Data Reference

chart.SetData c.chDimSeriesNames, 0, “A2“Variable name that will appear in legend

chart.SetData c.chDimValues, 0, “C2:C4“Cells containing value (y) axis data
