Universal Way To Connecting To Excel Through OleDB Connection?

Nov 17, 2011

A While back I developed a application that connected to Excel using DB connection. It worked fine since the application was designed for usage on one particular PC with Excel 2003. I especially liked the solution since the data retrieval was much faster compared to what I would get if I connected to Excel using Interop libraries.

However, recently when I tried to implement the same solution onto another app that would run on various PC that could use different versions of MS Office I ran into multiple problems. First of all, I can't use the same connection string on various versions. Also, the whole x64 vs x86 thing is adding to the problem.

I wonder if there is a way to check the version and use the apropriate connection string for every version?

Efficiency Of Oledb - Got 10+ Users Using Files, Via A Oledb To Put Info Into An Excel Spreadsheet

Oct 18, 2010

Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?
