RE: Follow up question. Get value of closed file.

1) I don't think you really know how to use arrays. You can't just put an
array into a mesage box. You havve to access each member of the array
individually.

a single dimension array
for i = 0 to upperbound(ReturnData - 1)
msgbox(returndata(i))
next i


a double dimension array
for i = 0 to upperbound(ReturnData - 1)
msgbox(returndata(i,0))
msgbox(returndata(i,1))
next i

I would unprotext the file for testing and add the password back after you
get everything working. I'm not sure of the syntax to add the pasword to the
commands for reading a close file.

Thank you Joel,

I cannot get it to work yet but I will continue trying. I tried to return
MsgBox ReturnData and it said type mismatch. And now I have an issue of
what if the file I am getting the data from is passworded? I feel I am
occupying your time and vastly superior knowledge. If you can give me one
last direction I would certainly appriciate it.

Thank you,

Steven

2) Change
from
ReturnData = Nothing
to
set ReturnData = Nothing

Joel,

Thank you for your response. I still cannot make it work. I setup what you
have for the Public Sub GetData(..............) ............. End Sub and
changed my GetData_Example3() to add , True at the end. When I tried to run
it it gave me an error first on ReturnData = Nothing.

My ultimate goal is to return the value of 1 cell in the closed file to a
variable, and if possible without writing the value to a cell. This is
definitely new ground for me. Can you show me how this works and then return
the variable at the end with MsgBox ......

Thank you,

Steven

You need to return an array. You can either make the routine a function and
return the array or pass the array as a parameter in the sub and make the
variable BYREF.

I earlier in the month asked how, in code, do you get the value of a cell

instead of putting the value in a work*** cell as this solution does, I
want to save the value to a variable. How do I do that?

Thank you,

Try an ADO macro ; first , copy this macro in a wbook !

Then , copy and this macro , too :

Sub GetData_Example3()
' In this example Header = False and UseHeaderRow can be True or False
because it is not used

GetData ThisWorkbook.Path & "\test.xls", "Sheet1", _
"A3:C4", Sheets("Sheet1").Range("A1"), False, False

End Sub

change test.xls , sheets name and range according with your needs ;
