I’m porting an Excel add-in from visual VB to Delphi 2006. Most of it

  • 0

I’m porting an Excel add-in from visual VB to Delphi 2006. Most of it is working but I am stuck on these two VB lines:

oXL.Selection.QueryTable
oXL.Selection <> ""

where oXL is defined as Excel.Application.

In Delphi ExcelApplication.Selection requires an index but in VB it doesn’t. I couldn’t find anything similar in C# either. I have tried ExcelApplication.ActiveCell which works as long as there is an existing query, otherwise Excel crashes.

Does anyone know what this translates into for Delphi, or C#?

Also if oXL.Selection is an interface, how can you perform oXL.Selection <> “”?

Thank you.

    No worries, I had forgotten that you can just cast the application IDispatch interface to an OleVariant and then call the method.

    But what I’ve done instead is just the following

    try
  ExcelApplication.ActiveCell.QueryTable.Refresh(False);
except
end;

    This seems to be the only way to make it work without crashing excel.
