VBA to open Excel file, refresh bloomberg data, save, close - vba

Question

I'm trying to write a vba script that gets called in a batch file to open an excel file, refresh bloomberg data, save the file, and then quit excel.
There was a historical question which asked something similar, but the suggested answer didn't seem to work - I can open the file and refresh the data, but it doesn't save the file or close excel.
I tried also putting in as a macro with the workbook_open file, but then ran into a problem where excel is saving and closing the file before refreshing the data. Any suggestions would be much appreciated.
Immediately below is the modified vba code that refreshes the data, but doesn't save or close the excel workbook.
'Write Excel.xls Sheet's full path here
strPath = "C:\MngXL\testbook.xlsm"
'Create an Excel instance and set visibility of the instance
Set objApp = CreateObject("Excel.Application")
objApp.Visible = True
Set wbToRun = objApp.Workbooks.Open(strPath)
StartAutomation
DoneNow
Sub StartAutomation()
Dim oAddin
Set oAddin = objApp.Workbooks.Open("C:\blp\API\Office Tools\BloombergUI.xla")
If Not oAddin Is Nothing Then
objApp.DisplayAlerts = False
objApp.Calculate
objApp.Run "RefreshAllStaticData"
objApp.Calculate
objApp.Run "RefreshAllStaticData"
'WaitTillUpdateComplete
End If
dim count
dim updated
updated = false
for count = 0 to 12
if updated = false then
if objApp.WorksheetFunction.CountIf(objApp.Range("rng_inWorkbook"),"#N/A Requesting Data...") = 0 Then
updated = true
else
Application.OnTime Now + TimeValue("00:00:15"), WaitTillUpdateComplete
end if
end if
next
End Sub
Private Sub WaitTillUpdateComplete()
Dim t
t = 0
objApp.Calculate
If objApp.WorksheetFunction.CountIf(objApp.Range("rng_inWorkbook"),"#NAME?") > 0 Then
Application.OnTime Now + TimeValue("00:00:15"), "WaitTillUpdateComplete"
ElseIf objApp.WorksheetFunction.CountIf(objApp.Range("rng_inWorkbook"),"#N/A") > 0 Then
Application.OnTime Now + TimeValue("00:00:15"), "WaitTillUpdateComplete"
ElseIf objApp.WorksheetFunction.CountIf(objApp.Range("rng_inWorkbook"),"#N/A Requesting Data...") > 0 Then
If t < 5 Then
t = t+ 1
waitlonger
Else
Exit Sub
End If
Else
Exit Sub
End If
End Sub
Sub waitlonger()
Dim x
x = Now + TimeValue("00:00:40")
Do While x > Now
Loop
objApp.Calculate
End Sub
Sub DoneNow()
wbToRun.Save
wbToRun.Close
objApp.DisplayAlerts = False
objApp.Quit
MsgBox strPath & " " & strMacro & " macro and .vbs successfully completed!!!!", vbInformation
End Sub

You need a strategy to let the refresh of Bloomberg data take about the right amount of time.
Currently, your program seems to allow only certain small amounts of time to pass with no feedback. Instead, you need to make a loop that cycles once every 10 seconds (or whatever makes sense) and checks to see if the program is done.
I like to do it this way:
dim count as integer
dim updated as boolean
updated = false
for count = 1 to 12 'or any value you choose
if updated = false then
if objApp.WorksheetFunction.CountIf(objApp.Range("rng_inWorkbook"),"#NAME?") = 0 Then
updated = true
else
Application.OnTime Now + TimeValue("00:00:15"), "WaitTillUpdateComplete"
end if
end if
next
