Dear Experts,

I want to call the VBA Excel functions with optional parameters like Range.PasteSpecial(...) for example in PowerScript functions.

I tried the following:

OLEObject lole_WS_From // Excel worksheet
OLEObject lole_WS_To    // Excel worksheet

(...)

 lole_WS_From.Rows("1:3").Copy // works

 lole_WS_To.Rows("1:3").PasteSpecial(-4163, -4142, False, False) // results in
                                                                                              // "Error calling external object function pastespecial"

Is it possible to call VBA Excel functions with optional parameters?

If it's possible: How is the syntax?

 

Thanks in advance for all trials to help me!

Kind regards,
Konrad Kaltenbach

Hi Konrad,

The issue isn't the passing of parameters as you do have the correct syntax and your range expression is fine as well. It may be how you're accessing/ selecting the second OLE object and without seeing the rest of your code (how both objects are connected to etc.) it's hard to tell. lole_WS_To...what is that used for? Is it to connect to another workbook? Are you using ConnectToObject? ConnectToNewObject?

Maybe I'm misunderstanding what you're trying to accomplish but it could be how you're trying to utilize/ access lole_WS_To.  You don't need to create another OleObject, you simply need to change the focus of the current workbook and sheet...using the same OleObject...to the new workbook and sheet.

So applying that to your code:

myoleobject.Rows("1:3").Copy
myoleobject.Windows("Book2").Activate
myoleobject.Sheets("Sheet2").Select
myoleobject.Rows("1:3").PasteSpecial(-4163, -4142, False, False)

Try the above changes and see if that works but it may well depend on the answers to the questions in the first paragraph.

HTH...regards,

Mark

Hi Konrad...just wanted to follow-up on my last message above regarding not activating the window and so you may wish to try the following:

myoleobject1.WorkBooks[2].WorkSheets[1].Rows("1:3").PasteSpecial(-4163, -4142, False, False)

This should allow you to paste the contents without having to activate the workbook first.

Regards,

Mark

Dear Mark,







thanks a lot for your elaborate and comprehensive answers and your additional thoughts!



On your question: I wanted Excel stay "passive" and hidden until the table is filled. But probably no problems will appear when the window is activated as you showed me.



Regarding your thoughts:



You're right: I didn't publish the complete code of the function where PasteSpecial is called but only an extract which I assumed to be complete with respect to the OLE objects and your queries.



"myoleobject1.WorkBooks[2].WorkSheets[1].Rows("1:3").PasteSpecial(-4163, -4142, False, False)" I will try next week. Thanks! But, yes, probably activating the window will not cause any problems.



Grateful regards,



Konrad

Hi Mark,

following your suggestion I tried the following:

xlsInstanz.Application.Workbooks[li_WBk].Worksheets[li_WS].Rows("1:3").PasteSpecial(-4163, -4142, false, false )

(cf. my source code posted Tuesday, 30 March 2021 09:05 AM UTC and the comment). The error still occurred (as long as the window is not activated before).

Dear Sir or Madam,

here is the complete source code:

ls_ws_to   = "Name of target sheet"

SetNULL( lole_WS_To )

    li_err = xlsInstanz.connecttoobject( ls_file )
CATCH (OLEruntimeerror er2)
    DESTROY xlsInstanz
    ls_err += "Description: ~n" + er2.Description + " " +  er2.getMessage()

    // "Error calling external object function pastespecial"


CATCH (OLEruntimeerror erKopfCopy)
    messagebox("", erkopfcopy.getmessage())
End Try

The error disappears if the the Excel window is activated (lole_win.Activate) between

lole_WS_From.Rows("1:3").Copy and lole_WS_To.Rows("1:3").PasteSpecial(-4163, -4142, False, False)

(cf. accepted answer by M. Goldsmith).

Without window activation the following three trials didn't work, too:

xlsInstanz.Application.Workbooks.Item(ls_wb).Worksheets.Item(ls_WS_to).Rows("1:3").PasteSpecial(-4163, -4142, false, false )

xlsInstanz.Application.Workbooks[li_WBk].Worksheets[li_WS].Rows("1:3").PasteSpecial(-4163, -4142, false, false )

xlsInstanz.Application.Workbooks(li_WBk).Worksheets(li_WS).Rows("1:3").PasteSpecial(-4163, -4142, false, false )

Hi Konrad...glad to hear you got this to work, even if only by activating it first. That being said, the syntax I provided which matches your second trial above does work. The only thing I can think of is that maybe your elements (for Workbooks and Worksheets) are off/ incorrect. From what I can see in the code above in your trials, the second two trials are using li_WS but in the first trial you are using ls_WS_to and in your original code posted March 30 you were using li_WS_to as the destination worksheet and so maybe that is where it is failing.



Again, glad to hear you got it working and thanks for the update.



Regards,

Mark

It's been a while since I worked with excel ole. I would suggest you to look at your range expression. PasteSpecial needs a valid range and probably Rows("1:3") is not valid. I found it helpful to test my syntax first in an excel macro.

Thanks for your comment! And sorry for the delay.



But "Rows("1:3")" works quite well.
