I have the following database defined in app.config now:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory| able.mdb
can I use excel instead as datasource there? are there any limits if I use excel file, the database is simple 300 rows, and it would be more handy to use excel file.does excel need to be readonly?
I made an application that was used by one person only, but now my boss told me that this application it'll be used by all company.I made the application with a dataset that have the datasource in a access database that's installed with the application. The user can add, delete and change values in the database, so i had to put the database in a sql server to everyone see the changes.There's someway to change the dataset datasource/connection string?

I'm able to add a new sheet to an excel ss and name it. But to tighten up the code I thought a counter was in order. So I tried a while loop.
[Code]...
A few oddities, for one this makes a total of 11 sheets. I thought this would make a total of 7. The first 3 then adding 4 from the while loop. I thought a counter starting at 0 then going to < 4 would add 4. Also I'm getting an error, noted in the code, it expects an end of statement. It doesn't like the +=. I'm trying to add to the sheet name/number of Taroko #. Maybe it's trying to start at 0 there. So I'll initialize the namectr to start at 2. No still doesn't work.
I think my syntax is simply bad for the statement..Sheets("Sheet4").Name = ("Taroko # " + nameCtr += 1) ' error here also tried & instead of +.
