When is a column not a column?
I have several extremely similar datawindows that I have to maintain that go against the same table. Recently, I had to add a column to that table, and also add the column to ALL of these datawindows that go against this table. I added the column to the first datawindow, set up the edit control style, etc. I then did a copy/paste of the columns edit control to the remaining dw's (of course remembering to first add the column in SQL). Everything (update props, column specs, column props) seems to indicate that the pasted column is linked to the column I selected, HOWEVER, when I retrieve, the column behaves as if it is not linked to the underlying SQL column. It seems that the cut and paste is REAL problematic, but without it, maintenance on these dw's is going to be a real pain. Any ideas on what might be going on? TIA, Bill Pfeiffer

Adding a column or modifying even the Data Type of a column in a DataWinodw is not so straightforward as it seems. There is a great feature though that I have used which is a life saver. Go to the Library painter, select the Datawindow, do a mouse right click and choose Export (also available under menu Entry). Edit this Exported file (it might be difficult to understand in the beginning) to include the new column. Once done do an Import into your library from the Library painter. This is sure to work.

datawindow.column.count not returning the column count of a datawindow
I am having problems with the datawindow.column.count property of a datawindow. It just started happening with PB 6.501 and still works fine in PB 5.0. The function that looks at this property is in an ancestor userobject. The dataobject is assigned at this point but all other properties of the datawindow are missing. Any suggestions? Don't recall, but was it still dwDescribe() in version 5.0? If it was that may be your problem.

Writing a column after column
Hi all, I need to consolidate columns of data available across different directories into a single excel csv file. Usually we write to a file row after row but for the current task I have, it would be convenient to write the file column after column. Is there a file writing mode for this? If not, I guess, I will have to write the matrix row by row and then take a transpose. Let me know what you guys think and if you could share some skeleton of code for something like this would be great.
