OLE Automation Access example

Here's an example of how you might use Milestones Profesional's OLE Automation to take information from an Access Table and generate a formatted schedule.

The "ScheduleData" Access table:

OutlineLevel	Task	Manager	Funding1999	Funding2000	StartDate	EndDate
1	Task 1	Jane	$333.00	$123.00	2/10/99	9/14/00

2	Task 4-2	Donald	$332.00	$232.00	4/4/99	11/26/00
2	Task 4-3	Mary	$332.00	$232.00	4/4/99	12/29/00
2	Task 4-4	Jim	$332.00	$232.00	4/4/99	8/4/99

The Milestones Professional Schedule:

The Access Visual Basic Program:

Here's a Visual Basic Program that generates an outlined Milestones Professional schedule using the data in the Access table. The Milestones OLE calls are displayed in red.

Public Sub CreateSchedule()

' this function updates the schedule using data from a table

Dim dbsCurrent As Database
Dim rstTable1 As Recordset
Dim numberoftasklines As Integer
Dim numberofsymbols As Integer
Dim x As Integer
Dim x2 As Integer
Dim TaskNumber As Integer

'Identify the table
Set dbsCurrent = CurrentDb()
Set rstTable1 = dbsCurrent.OpenRecordset("scheduledata", dbOpenTable)
Set objMilestones = CreateObject("Milestones")

With objMilestones
' Locate first record.
rstTable1.MoveFirst
' Activate Milestones Professional Schedule
.Activate
.Template "AccessTemplate.mtp"
.Refresh

TaskNumber = 0

'Start of loop

Do Until rstTable1.EOF
TaskNumber = TaskNumber + 1

On Error GoTo SkipDate

'Use Milestones Professional OLE Automation calls to add symbols to the schedule

.AddSymbol TaskNumber, Format(rstTable1!StartDate, "mm/dd/yy"), 1, 1, 2
.AddSymbol TaskNumber, Format(rstTable1!EndDate, "mm/dd/yy"), 2, 1, 2

.SetOutlineLevel TaskNumber, rstTable1!OutlineLevel

SkipDate:
'Add information to the task columns
.PutCell TaskNumber, 1, rstTable1!Manager
.PutCell TaskNumber, 3, rstTable1!Task
.PutCell TaskNumber, 6, "$" + Str(rstTable1!Funding1999)
.PutCell TaskNumber, 7, "$" + Str(rstTable1!Funding2000)
.RefreshTask TaskNumber

'Move to the next record
rstTable1.MoveNext
Loop

' End of loop.

.SetLinesPerPage TaskNumber
.SetTitle1 "ACCESS OLE AUTOMATION EXAMPLE"
.SetTitle2 "Milestones Professional"
.SetStartDate "1/1/1999"
.SetEndDate "12/31/2000"
.Refresh

'Close Access Table
rstTable1.Close

'Keep Milestones Professional schedule open
.KeepScheduleOpen
End With

Exit Sub

End Sub
