debugging

问题 I use Delphi 10.3.1 COMMUNITY version and can't look into generic tList while I debug the project. I know the latest version of Delphi doesn't support the old-typed debug feature which allows to look into generic tList. So I used tList.List in the following code to evaluate the tList. In tList<tRecord>.List I can look into it but can't do it in tList<Integer>.List . type tRecord = record Field: Integer; end; procedure TForm1.FormCreate(Sender: TObject); var _Record: tRecord; _List1: TList

问题 I have a form and when someone saves it I want it to display it in a blog format on my first page. I am getting an error when I click on the "Save" button. The error is: Unhandled Rejection (TypeError): _this.props.onSave is not a function On the line below: handleSave = (e) => e.preventDefault(); const id = this.prop .onSave(this.state.post); How can I resolve this error? I am using Nextjs with Typescript. Here are both my files App.tsx(Routing ) and NewQuestion.tsx(Save button) export

问题 I am aware of siiar questions, such as Angularjs 1.7.9 - Possibly unhandled rejection and those mentioned in it as duplicates. However, my code does not use promises (that I am aware of; certainly no $promise or $http ). I am just knocking up a simple ui-router demo for a friend. It is just two views, each with a button that toggles to the other view. It works just fine with AngulrJs 1.5, and breaks with the above error in 1.7. A simple as it is, it's a bit too much code to post. In case,

问题 I am using IBM Worklight 6.1 and trying to deploy on production server. On my development server, everything works fine, but once I deploy, and then try to preview the app on browser, I have a loop of js errors saying: Request [/MyApp/apps/services/api/MyApp/common/init] worklight.js:4558 POST http://172.16.1.2:9080/MyApp/apps/services/api/MyApp/common/init 401 (Unauthorized) worklight.js:1081 Request [/MyApp/apps/services/api/MyApp/common/init] worklight.js:4558 POST http://172.16.1.2:9080

问题 I want to add a keyboard shortcut for the command 'Debug: evaluate' in Visual Studio Code. Unfortunately, the command ID for the command 'Debug: evaluate' is not documented. Did someone know where to find the commandId ? 回答1: editor.debug.action.selectionToRepl is what you are looking for. It will execute the current selected text in the debugger console. https://github.com/Microsoft/vscode/blob/d2b6bbb46fbdf535e2c96b3e00ac56ac1d427a69/src/vs/workbench/parts/debug/browser/debugEditorActions

问题 I recently came around this article (http://www.splinter.com.au/2014/09/16/storing-secret-keys/) that talks about obfuscation on iOS. I quote: To somewhat mitigate the risk of crackers attacking your app with a debugger (LLDB or GDB), you can insert some code in your app that makes it crash as soon as it detects a debugger attached. The iTunes app uses this technique, you can read about it here. This is achieved by calling the following code in main() #import <dlfcn.h> #import <sys/types.h>

问题 In a C# app, I'm referencing a native C static lib, that I wrapped in a C++/CLI DLL. I chose a static lib versus a DLL because I have other constraints related to the release process of the app to the user. Among the many topics available on this forum I found the following implementation. Main : { MyCLRDLL test = new MyCLRDLL(); if(test.go()) Console.WriteLine("Hello, wrld"); } In the DLL project, the file MyCLRDLL.hpp #include "MyNativeLib.h" #pragma comment(lib, "MyNativeLib.lib")
