I have a problem with the DeleteRows method of the XLSReadWriteII4 component.

The task I try to accomplish consists of importing several CSV files, all with the same header row, into one worksheet.
For all files except the first I want to delete the header row, producing one contigious list of entries with a header row only at the top.
The code goes like this:

// Obtain at which row to insert next file:
NextRow:=XLS.Sheets[NoSheets-1].LastRow+1;
if NextRow=1 then
NextRow:=2;
if not ImportCSV(XLS, NoSheets-1, 0, NextRow, FullName, ';', False) then
Log('CSV import of '+Fullname+' failed');
// If not first file imported, delete header row:
if NextRow>2 then
with XLS.Sheets[NoSheets-1] do
begin
Log('Deleting row '+IntToStr(NextRow));
XLS.DeleteRows(NoSheets-1, NextRow, NextRow);
end;

The strange thing is that for some of the files the deletion of the intermediate header row is successful, but for others only the cell contents is cleared, leaving a blank row in between
I have tried both XLS.DeleteRows() and XLS.Sheets[].DeleteRows but same result.

Anything I have missed?

Hello

You uses DeleteRows correct.
Can you create a test case that I can use to reproduce this problem?

Thank you for your prompt reply Lars!

Unfortunately I don't have the time to send you anything now, to complete the project in time I went for another approach, namely by importing each .CSV file into a temporary sheet and then copying rows using the method TXLSReadWriteII4.CopyRows.
I'll see whether I can prepare something next week.

BTW, I'm not quite sure when I have to call CalcDimensionsEx to obtain the correct dimensions of a sheet.
Which operations on a sheet requires this method to be called explicitly, and which update the dimensions automatically?
