I'm looking to create a simple web service that when polled returns a unique id. The ID has to be human readable (i.e. not a guid, probably in the form 000023) and is simply incremented by 1 each time its called. Now I need to consider that it may be called by two different applications at the same time and I don't want it to return the...
Hi, i have custom cell with 2 buttons(the function of these buttons is just to disable the button that was pressed). When i use dequeueReusableCellWithIdentifier in this classic way: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; cell = ...
Hi guys, I'm working on shifting my local web application to google apps. I have an account already for google apps for business and right now I need to work on the functionality of interacting with email. Let me give a synopsis - my web app currently was set up that a cron job would download all emails from a set mailbox into a databas...
I am writing large MS Word 2007 documents, which are often being changed. I have to number paragraphs with stationary unique numbers, that will not change while changing the documents. The numbers should be unique, and will not change even if previous numbers are deleted. The order of the list is not mandatory, and addition of a new numb...
We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs). So, it seems there are basically two options here (short of throwing out GUIDs as PKs altogether, which we cannot do (at least not at this time)). We could chan...
I have to digitize a few thousand physical documents and assign them to a variety of categories for a web app where they will be displayed. Should I generate bar codes for each of the documents to uniquely identify them? If so, how can I avoid the barcode being present in the scanned image? Any other recommendations for approaching th...
I have some data that comes regularily as a dump from a data souce with a string natural key that is long (up to 60 characters) and not relevant to the end user. I am using this key in a url. This makes urls too long and user unfriendly. I would like to transform the string keys into integers with the following requirements: The source...
I am writing a C# application which allows users to store emails in a MS SQL Server database. Many times, multiple users will be copied on an email from a customer. If they all try to add the same email to the database, I want to make sure that the email is only added once. MD5 springs to mind as a way to do this. I don't need to worry ...
I am trying to cast an AuctionId that is a UNIQUEIDENTIFIER to an varchar(36) and then back to an UNIQUEIDENTIFIER. Please help me. CAST((SUBSTRING(CAST([AuctionId] as VARCHAR(36)), 0, 35) + '1') AS UNIQUEIDENTIFIER) But I keep getting this error: Msg 8169, Level 16, State 2, Line 647 Conversion failed when converting from a c...
I'm wondering how SQL Server orders data that is returned from a query and the Id columns of the respective tables are all of type uniqueidentifier. I'm using NHibernate GuidComb when creating all of the GUIDs and do things like: Sheet sheet = sheetRepository.Get(_SheetGuid_); // has many lines items IList<SheetLineItem> lineItems = sh...
I'm creating a control based on ScriptControl, and I'm overriding the Render method like this: protected override void Render(HtmlTextWriter writer) { RenderBeginTag(writer); writer.RenderBeginTag(HtmlTextWriterTag.Div); writer.Write("This is a test."); writer.RenderEndTag(); RenderEndTag(writer); } My question i...
When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, htt...
Do Android devices have a unique id, and if so, what is a simple way to access it via java? ...
Does wx provide a handy way to get anything like this in a platform-independent way? I don't think C++ libs themselves provide anything. I don't have a definite idea what should be used for the unique ID... MAC address is common but what else could be used? If we were doing it Windows-specific, is there a way to get the actual Windows ...
I need a way to uniquely and permanently identify an instance of the JVM from within Java code running in that JVM. That is, if I have two JVMs running at the same time on the same machine, each is distinguishable. It is also distinguishable from running JVMs on other machines and from future executions on the same machine even if the...
Basically I want to use uniqueidentifier in similar way as identity. I don't want to insert values into it, It should just insert values automatically, different value for each row. I'm not able to set autoincrement on columns of type uniqueidentifier(the property 'autoincrement' is set to false and is not editable). ...
Question: I have to come up with unique ID for each networked client, such that: it (ID) should persist once client software is installed on target computer, and should continue to persist if software is re-installed on same computer and same OS installment, it should not change if hardware configuration is modified in most ways (excep...
Hello, I have this function that creates a unique number for hard-disk and CPU combination. GetVolumeInformation(drv, szNameBuffer, 256, &dwHddUnique, NULL, NULL, NULL, NULL); SYSTEM_INFO si; GetSystemInfo(&si); dwProcessorUnique = si.dwProcessorType + si.wProcessorArchitecture + si.wProcessorRevision; dwUniqueKey...
i see after installing the asp.net membership tables, they use the data type "uniqueidentifier" for all of the primary key fields. I have been using "int" data type and doing increment by one on inserts and declaring the column as IDENTITY. Is there any particular benefits to using the uniqueIdentifier data type compared to my current ...
Hi there, I am using C++ and MySQL. I have data objects I want to persist to the database. They need to have a unique ID for identification purposes. The question is, how to get this unique ID? Here is what I came up with: 1) Use the auto_increment feature of MySQL. But how to get the ID then? I am aware that MySQL offers this "SELEC...
