Class Not Registered Error In Vis Studio IDE

Microsoft OFFICE


  • 1. Excel XP save as website - problem with hyperlinks
    I recently created a fairly large spreadsheet where I Save As a Website and it creates a fully linked xlHTML website using the hyperlinks from the spreadsheet. This worked fine in Excel 2000. I have tried producing the same thing in Excel 2002 and this does not work. When I open the resulting xlHTML file the links do not work. For example, instead of linking to the correct sheet in the file that Excel creates when it produces the site, it instead tries to always link to sheet001 followed by a #[name of sheet it should be linking to] - so it thinks that the sheet I am trying to link to is a reference tag on the first sheet of the workbook. Anyone come across this and know a way around it? Much appreciated
  • 2. Repost: Pivot Table - get rid of expand indicators
    Recent editions of pivot table have a propery called DisplayExpandIndicator - and I expected that it would hide the zillions of + and - expand markers that are evident in pivot tables. But setting DisplayExpandIndicator does not do this. What is it supposed to do then? What I am interested in getting rid of are the spurious + and - markers that appear at every row and column of a pivot table even when there are no child cells, ie no point in the markers being shown. They really clutter up the screen.
  • 3. Formulas in Pivot Tables?
    I need information in how to add formulas and calculation on pivot tables. Thanks-

Hello -

I'm using the Spreadsheet WebComponent in a WinForms application.

Because I wanted to handle events from the WebComponent, I followed the 
instructions in the MS KB article 
( http://www.**--****.com/ ) and recompiled the OWC11 dll.

After recompiling, I was left with the following dlls:

I then opened up Vis Studio 2003, and added the AxOWC11.dll components to my 
Toolbox: AxChartSpace, AxPivotTable, AxSpreadsheet.

I created my WinForm and compiled my project. I then went to a different 
development machine, but brought all my DLLs. I added the same components to 
my Toolbox, but when I try to drag any of the components over to a Form, I 
get a MsgBox with the following error "Class Not Registered".

The only thing I know is that my first development box had Office 2003 
installed (I'm using OWC11) and the second development box had Windows XP 

Hence, I cannot develop on this second machine. Does anybody know how to 
either "Register" my recompiled OWC11 DLLs or know to resolve this issue.

OWC must be installed on your machine for OWC to work. The events walkthru 
only prepares a suitable RCW. Install the OWC components on that machine.
