    Thread: Database operation exception handling
Post: RE: Database operation exception handling

I don't think so. You can put your commit or rollback inside its own 'try' block to check if it ran correctly, or you can use the same 'try' for all the transactions sequence.

My understanding of wmi is you cannot use it on linux, because it's a wrapper on a windows dll. One way I see is to install cygwin, by this way you will have a linux emulation on your windows pc, et s...
