问题 I have one table called customer_master that includes a column called cust_id with autoincrement set to 1. When we try to insert records its working fine and inserted records like cust_id 1, 2, 3 and 4 are inserted, but when an error is generated in the insert command we do a transaction rollback, this means that cust_id 5 is not inserted, but when we are insert another record, cust_id generates 6. It skips cust_id 5. I want to set it up so that if any error is generated in the insert command

问题 I am very interested in using the new service recently released for secret management within Azure. I have found a few example guides walking through how to interact with key vault via powershell cmdlets and c#, however haven't found much at all in regards to getting started with using the rest API. The thing I am particularly confused with is the handling of oauth2 w/ active directory. I have written a oauth2 application listener, built a web application with an AD instance and can now

问题 Scenario: I have received auto generated project in ASP.NET CORE from my colleague. There is auto-generated code for Account/Manage service. This code includes ApplicationUser Class, DBContext and migration folder with 00000000000000_CreateIdentitySchema.cs and 20180323155805_Snapshot.cs. I have been trying to change my User class to have integer id. To do that I added generic to IdentityUser: public class ApplicationUser : IdentityUser**<int>** { } I also had to create ApplicationRole class,

问题 I want to identify disk in c++ in my windows application. For example: I have a disk on E:\ Then I changed the disk, and replace it with another one. the name is still E:\ How can I know the disk is changed, it is not the original one? If I have no administrator priority in win7, Can I still use some method to identy different disks? Many thanks! 回答1: Probably the relevant methods are: GetLogicalDrives() BOOL WINAPI GetVolumeInformation( __in_opt LPCTSTR lpRootPathName, __out LPTSTR

问题 I use the identity function in all my JavaScript programs: function identity(value) { return value; } The reason is that I often need differentiate between primitives types ( undefined , null , boolean , number and string ) and object types ( object and function ) as returned by the typeof operator. I feel using the indentity function for this use case very succuint: if (new identity(value) == value); // value is of an object type if (new identity(value) != value); // value is of a primitive

问题 I have a project in .net core 3.0 with 3 parts : api, shared and a blazor app. I added few models in shared project and a user model : [Table("user")] public class User : IdentityUser<Guid> { [Required(ErrorMessage = "Firstname is required")] [StringLength(32, ErrorMessage = "Firstname must be 32 charaters maximum")] [Column("firstname")] public string Firstname { get; set; } [Required(ErrorMessage = "Lastname is required")] [StringLength(32, ErrorMessage = "Lastname must be 32 charaters

问题 I use a ribbon in Excel 2010, which contains a single button: <customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="rx_onLoad"> <ribbon> <tabs> <tab id="TestTab" label="Test Tab" insertAfterMso="TabHome"> <group id="TestGroup" label="TestGroup"> <button id="TestButton" label="TestButton" size="normal" onAction="OnTestButton" tag="TestButton" imageMso="Coffee" /> </group> </tab> </tabs> </ribbon> </customUI> The method OnTestButton is implemented in a module Sub

问题 The id() inbuilt function gives... an integer (or long integer) which is guaranteed to be unique and constant for this object during its lifetime. The is operator, instead, gives... object identity So why is it possible to have two objects that have the same id but return False to an is check? Here is an example: >>> class Test(): ... def test(): ... pass >>> a = Test() >>> b = Test() >>> id(a.test) == id(b.test) True >>> a.test is b.test False A more troubling example: (continuing the above)
