Active 7 months ago. Viewed k times. Jim G. The easiest way is to do a nested foreach loop on items and subitems. NOTE: If you're trying to pass values from a data table to an object then to Excel, you should be doing datatype error handling as well. One work around without testing for datatypes is to use "ToString " when populating your object.
Excel will convert numbers back to number format on its own. I would recommend the answer on this question: stackoverflow. Add a comment. Active Oldest Votes. Add dt,"WorksheetName" ; The developer is responsive and helpful. Julien N 3, 4 4 gold badges 27 27 silver badges 44 44 bronze badges.
Good question MicheleVirgilio. I haven't done any testing to quantify an impact. But for what it's worth, it hasn't bothered me in any of the projects I've used it, in fact I can't say that I've ever noticed it. This code returned me an excel with a single column with value ClosedXML.
XLWorkbook — It's a trap. Adding large datatable's k rows in my case resulted in out of memory with ClosedXML and its a known open issue — glant. How to populate in the current open excel?

There are, of course, loopholes The NVG was the last one they offered forsale. Buying one on eBay is buying someone else's rented but unreturned box -- with or without an ETF. I have several that were left behind by previous business tenants; when the wall is being demo'd, I'll take the technology off of it.
Best I can figure, they're "falling off a truck". Or the Chinese factory is churning out a few extra, and you should never trust those. As I have proven you wrong in past with links to ordering pages and quotes, you can purchase the gateway from 3rd party service resellers.
You legally own it at that point. You must have a very short or selective memory. It was quite a recent thread. No difference at all. So you are wrong, and judging from your admission to that by mentioning 3rd party resellers you know that too.
Most websites e. Snailbook are far slower than that. And you're reading comprehension is still just as bad. Returning the one they provided for one you got on ebay doesn't change that; when you terminate service, they will expect the active box back. And, eBay is the only path to get one yourself. There's no retail path to get one. T doesn't sell them. There's no class action suit s because no lawyer will touch it, because they can't win. All a suit would do is get T to track serial numbers, and no "used" box will ever work again.
And your luck is the same with or without an eBay'd box. Anon6af5b I just checked Toast. How much is T's current price? Not promotional; the ongoing price. Toast is still operating under an older agreement. Well, I'd much rather a vendor put all the costs in the advertised price vs T's song and dance with advertising a price that a customer can never achieve. I don't know that any T retail pricing structure is inside Toast's retail pricing structure. And that's what caused a truck roll inside T's system; my new rate with Toast was technically a new T account in the back end system.
Never mind that I had been with Toast for awhile at that point. Also, Toast at one point very recently had only Their offerings have bounced around a few times over the past couple of years. It always pays to pay attention. If anything, their current offerings are very very recent.
That all makes me think, this isn't an older agreement at all. It makes me think they've been through a couple agreements over the last 2 years. I say the same thing about T-Mobile. At that point you own the gateway. They have no process for you to buy the RG, so they will ship and charge for one.
Even if you already have one, they will assume ownership -- they have no way to indicate "customer owned" -- and bill you for it.
