type-mismatch

问题 I have a pretty simple code that's supposed to transform a list of tuples (int * string), into two lists, one list of ints and one list of strings - basically a list of tuples into a tuple of lists. fun unzip_single_int[] : int list = [] | unzip_single_int(x::xs) : int list = x :: unzip_single_int(xs) fun unzip_single_string[] : string list = [] | unzip_single_string(x::xs) : string list = x :: unzip_single_string(xs) fun unzip[] : (int list * string list) = ([], []) | unzip([twopls]) : (int

问题 I’m trying to export all of the documents and their attachments from a Lotus Notes database (with Designer 7.0). I can get the document data and can get an attachment, but only if I hard code the name. The two methods, in LotusScript, I’ve found for getting the filename programmatically aren’t working, as shown in the lower two code blocks. In the first, doc.GetFirstItem( "Body" ) returns Nothing, and in the second, there’s a Type Mismatch during execution on the Forall line. Any help on how

问题 The code below is from one of the classes in a SDK jar I'm using in my app. How did it compile with int as the type for the indexSize, bestWidth, etc. below? config = this.mCamera.getParameters(); int indexSize = false; int bestWidth = false; int bestHeight = false; int maxRes = false; ZZZCLog.d("Camera supported sizes"); List<Size> supportedSizes = config.getSupportedPreviewSizes(); for(int i = supportedSizes.size() - 1; i >= 0; --i) { ZZZCLog.d(((Size)supportedSizes.get(i)).width + " " + (

问题 When I try to access the URL like for example localhost:8080/edit/12 I get an error on the console and I can't access the id from it, is it the problem in the versions used on the package.json or in the webpack config file? Component EditExpensePage: import React from "react"; const EditExpensePage = (props) => { return ( <div>This is from EditExpensePage component at {props.match.params.id}</div> ); }; export default EditExpensePage; Component router AppRouter: import React from "react";

问题 Here is my problem, when I receive some JSON, it happens that some values do not match the required type. I don't really mind, I'm only interested by the value when its type is correct. For instance, the following structure: struct Foo : Decodable { var bar : Int? } I'd like it to match these JSON: { "bar" : 42 } => foo.bar == 42 { "bar" : null } => foo.bar == nil { "bar" : "baz" } => foo.bar == nil Indeed I'm looking for an optional Int , so whenever it's an integer I want it, but when it's
