  - by Ian Ringrose

  We are having problems on one machine, with the error message: "MSDTC on server XXX is unavailable." The code is using a TransactionScope to wrap some LingToSql database code; there is also some raw Ado.net inside of the transaction.

• Truncate C++ string fields generated by ostringstream, iomanip:setw

  - by Ian Durkan

  In C++ I need string representations of integers with leading zeroes, where the representation has 8 digits and no more than 8 digits, truncating digits on the right side if necessary. I thought I could do this using just ostringstream and iomanip.setw(), like this: int num_1 = 3000; ostringstream out_target; out_target << setw(8)…

• SQL Server: What locale should be used to format numeric values into SQL Server format?

For example, if the current locale is bengali, then the number 123456789 would come out as "?????????". And that's just the digits, nevermind what the digit grouping would be. But…

My example here is ridiculously abstracted, so I doubt it will be…
