Am automating Excel with Xojo. It seems that the method "End" in Class ExcelRange is missing. Example: xlsheet.Cells(...).End(...)
Any suggestions for a workaround?

Oops! it's there ...
So why doesn't this compile?
dim lastrow as integer = xlsheet.Cells(100, "A").End(-4162).Row
@Mike L So why doesn't this compile?
dim lastrow as integer = xlsheet.Cells(100, "A").End(-4162).Row
What’s the error message?
Good morning Mike,
@Mike L dim lastrow as integer = xlsheet.Cells(100, "A").End(-4162).Row
The word 'End' is a reserved word in Xojo. I tried the following line of code with an underscore behind End and it works on my machine:
dim lastrow as integer = xlsheet.Cells(100, "A").End_(-4162).Row
Here is some example code that returns the correct value of 50 in Column A:
Sub Action() Handles Action Dim excel as new ExcelApplication excel.Workbooks.Add excel.Visible = True //Fill some rows with data Dim i as Integer For i = 1 to 50 excel.Range("A" + CStr(i)).value ="5" excel.Range("B" + CStr(50+i)).value ="6" Next i //Show the number of rows Dim answer as String Dim LastRow as Integer LastRow = Excel.Cells(100, "A").End_(-4162).Row MsgBox "The number of rows that have data" + chr(10) + chr(13) +_ "in column A is: " +LastRow.ToText End Sub
Happy to help. :)
Edit: Removed old commented code
Um, that code that causes a misleading result message if the data in the column is not contiguous.
Right after the For/Next loop, I added
Excel.Range("A77").value = "3"
which adds the value of 3 in cell A77. The number of rows in column A that contain data is now 51, but your code returns 77. So what you are actually returning is the number of the last row in the column that has data. The code is correct, the msgbox is misleading.
Thanks Dale. Yes, I want the last row in the column that has data. Great! Yes, a global replace fixed this problem everywhere (at least at compile-time). Testing is someway off yet :-)
Thanks, Eugene and Dale.
Have now a fully operational version in Xojo of the VB6-VBA Excel application. Only one type of VBA instruction is not working:
Purpose: to name a Trendline on an Excel plot.
Original VBA:
xlchart.SeriesCollection(2).Trendlines.Add(Type:=xlPolynomial, order:=2, Forward:=0, Backward:=0, DisplayEquation:=False, DisplayRSquared:=False, Name:="Upper two-sided 95% Confidence Interval")
In Xojo, this part works:
xlchart.SeriesCollection(2).Trendlines.Add (xlPolynomial,2)
This part doesn't:
xlchart.SeriesCollection(2).Trendlines.Name = "Upper two-sided 95% Confidence Interval"
nor does this :
xlchart.SeriesCollection(2).Trendlines.Name ("Upper two-sided 95% Confidence Interval")
nor does this:
xlchart.SeriesCollection(2).Trendlines(1).Name = "Upper two-sided 95% Confidence Interval"
nor does this:
xlchart.SeriesCollection(2).Trendlines.Add (xlPolynomial,2,0,0,0,False,False, "Upper two-sided 95% Confidence Interval")
Any suggestions?
Here you have 0,0,0:
xlchart.SeriesCollection(2).Trendlines.Add (xlPolynomial,2,0,0,0,False,False, "Upper two-sided 95% Confidence Interval")
and the original VBA only has 2 (Forward=0, Backward=0). Could that be?
Hi Alberto. Thanks for the reply.
The original VBA does not include the Intercept:= parameter. This is included in MSOfficeAutomation.rbx which says:
Function Add(Type_Param as integer, Order_Param as variant, Period_Param as variant, Forward_Param as variant, Backward_Param as variant, Intercept_Param as variant, DisplayEquation_Param as variant, DisplayRSquared_Param as variant, Name_Param as variant) as ExcelTrendline
And here is ExcelTrendline
Class ExcelTrendline
inherits OLEObject
dim Application as ExcelApplication
dim Backward as integer
dim Border as ExcelBorder
dim Creator as integer
dim DataLabel as ExcelDataLabel
dim DisplayEquation as boolean
dim DisplayRSquared as boolean
dim Forward as integer
dim Index as integer
dim Intercept as double
dim InterceptIsAuto as boolean
dim Name as string
dim NameIsAuto as boolean
dim Order as integer
dim Parent as OLEObject
dim Period as integer
dim Type as integer
Function ClearFormats() as variant
Function Delete() as variant
Function Select_() as variant
End Class
Does this provide any clues?
Hi Mike,
I started a new conversation at: Add Excel trendline Name to answer your new question. :)
