guid

I have an excel file with one order on each row, and I want each order to have a unique identifier, so there will be a Unique ID column. Every time I fill a row, I want Excel to automatically populate the Unique ID column for me. I did some research and was pointed in the direction of GUIDs. I found the following code: Function GenGuid() As String Dim TypeLib As Object Dim Guid As String Set TypeLib = CreateObject("Scriptlet.TypeLib") Guid = TypeLib.Guid ' format is {24DD18D4-C902-497F-A64B-28B2FA741661} Guid = Replace(Guid, "{", "") Guid = Replace(Guid, "}", "") Guid = Replace(Guid, "-", "")

I have problem that is really easily solved with Guids. In particular, for a password reset workflow, I would like to send a Guid token to a user's email and have them reset their password using the token. Since guids are unique, this is pretty secure and saves me emailing people passwords, which is risky. I noticed there is one Guid gem for Ruby; but it looks quite old, and it writes stuff to the file system. Does anyone know of any other gems that can create a globally unique identifier? I know I can just fall back to: (0..16).to_a.map{|a| rand(16).to_s(16)}.join But it does not really seem

I've been looking at the code in this tutorial , and I found that it uses My.Computer.Name to save settings that shouldn't roam between computers. It's entirely possible, however, for a user to have two identically named PCs. If they wanted to have the same username on each PC, for example, they may very well end up with two PCs named Username-PC. What are some good methods of identifying different PCs? Do PCs have GUIDs associated with them, or should I look into pulling the serial number off of some hardware? I don't care if the identification persists through reinstallation of Windows. (The

One field of our struct is Guid type. How to generate a valid value for it? Guid id = Guid.NewGuid(); Adam Driscoll Guid.NewGuid() creates a new random guid. There are two ways var guid = Guid.NewGuid(); or var guid = Guid.NewGuid().ToString(); both use the Guid class, the first creates a Guid Object, the second a Guid string. Guid.NewGuid() will create one var guid = new Guid(); Hey, its a 'valid', although not very useful, Guid. (the guid is all zeros, if you don't know. Sometimes this is needed to indicate no guid, in cases where you don't want to use a nullable Guid) reza.cse08 To makes an

突然ですが、皆さんは、馬に乗ったことはありますか？・・・このお話にご興味のある方は本文の最後の【閑話休題】までどうぞ。 さて、今回は、 Event Tracing for Windows (ETW) についてお話ししようと思います。ドライバ開発者の方にとって、なぜ、 ETW が必要なのでしょうか？読者の皆様にもご経験があるかもしれませんが、エンドユーザ様の運用環境の現象を、開発側で再現できない場合や、開発側でカーネルデバッガを接続し、Checked Build 版ドライバでデバッグプリントを出力すると、タイミングが変わって現象が再現しない場合があります。このような時、ドライバに ETW を実装しておくと、エンドユーザ様の運用環境で現象を再現することさえできれば、追加で何かをインストールする必要なく、かつ、パフォーマンスに影響を与えることもほとんどなく、デバッグプリント並みの詳細なログが取ることができるのです。追加で何かのインストールが必要ない、というのは、 OS にすでに入っているツール (logman.exe) を使ってログを採取することができる、ということです。ただ、一方で、「 イベントログの出力方法 」の記事にも書いた通り、常時採取するには向いていません。短時間でもデータ量が非常に多くなってディスクスペースを圧迫する可能性がありますし
