Hi, It''s been a late frustrating night. I have tried several ways to copy one workbook to another in memory (I have a baseline workbook, that has 15 sheets in it that I need to make several copies of to pump data into).
Is there a easy way to do this? like:
IWorkbook newWB = oldWB.CopyToNew()
I want to do this in memory to speed up my app vs. doing a disk based copy.....
I have tried cut/paste to clipboard - it crashes.
I have tried copying the sheets collection from one to the other with AddCopy() - it crashes.
Finally I wrote a loop and tried to use AddCopy() on each worksheet.. - it crashes..
Here is the code sinppet and exception... Please tell me what is wrong....
----------------------------------------
IWorkbook workbook = application.Workbooks.Create();
for (int i = 0; i < templateWorkbook.Worksheets.Count; i++ )
{
workbook.Worksheets.AddCopy(templateWorkbook.Worksheets[i]);
}
------------------------------------------
