由 為{幸葍}努か 提交于 2021-01-04 05:35:30
问题 I can't read the file from the root directory. How to do it? I use the command for reading Java.Lang.Process suProcess = Java.Lang.Runtime.GetRuntime().Exec(new string[] { "su", "-c", "cat /data/misc/vpn/state" }); but how do I get an answer? 回答1: The Java.Lang.Process class has some interesting Streams you will need to read from. InputStream and ErrorStream . First of all, after you have created your process, you will need to wait for it. This can be done nicely with .WaitForAsync() . This

Google sheets: Class google.script.run not working

问题 My problem is simple. All the possible solutions I searched for online did not address my question. Google's developer website for Class google.script.run (https://developers.google.com/apps-script/guides/html/reference/run#withSuccessHandler) showcased the method myFunction(...) (any server-side function). I have copied their exact code and html code and deduced that the function doSomething() does not execute. Nothing gets logged. I intend to use this to execute an HTML file so that I could

动态SQL和PL/SQL的EXECUTE IMMEDIATE

由 一曲冷凌霜 提交于 2020-11-24 03:15:23
动态 SQL 和 PL/SQL 的 EXECUTE IMMEDIATE 选项 EXECUTE IMMEDIATE代替了以前Oracle8i中DBMS_SQL package包.它解析并马上执行动态的SQL语句或非运行时创建的PL/SQL块.动态创建和执行SQL语句性能超前，EXECUTE IMMEDIATE的目标在于减小企业费用并获得较高的性能，较之以前它相当容易编码.尽管DBMS_SQL仍然可用，但是推荐使用EXECUTE IMMEDIATE,因为它获的收益在包之上。 使用技巧 1. EXECUTE IMMEDIATE将不会提交一个DML事务执行，应该显式提交 如果通过EXECUTE IMMEDIATE处理DML命令，那么在完成以前需要显式提交或者作为EXECUTE IMMEDIATE自己的一部分. 如果通过EXECUTE IMMEDIATE处理DDL命令,它提交所有以前改变的数据 2. 不支持返回多行的查询,这种交互将用临时表来存储记录(参照例子如下)或者用REF cursors. 3. 当执行SQL语句时，不要用分号，当执行PL/SQL块时，在其尾部用分号. 4. 在Oracle手册中，未详细覆盖这些功能。下面的例子展示了所有用到Execute immediate的可能方面.希望能给你带来方便. 5. 对于Forms开发者,当在PL/SQL 8.0.6.3.版本中，Forms

Dart & Flutter: How to call for a class method inside another class

问题 new to Dart here, sorry in advance if this is a redundant question; I couldn't find the answer. I created a function simulateRequest and then passed it to its own class SimReq and saved it in a file on its own. I imported the class in the main file, but when I try to execute it, I get an error, here is the class code: class SimReq { void simulateRequest() async { // first future holds family name String famNameFunc = await Future.delayed(Duration(seconds: 2), (){ String famName = 'Shanshi';

Swift - Execute code on LaunchScreen [duplicate]

由 半腔热情 提交于 2020-05-29 04:50:08
问题 This question already has answers here : iOS Launch screen code not running (2 answers) Closed 5 years ago . In iOS there is an LaunchScreen before you're app is ready. Can you add things to do (Code) to this? I want to execute a JSON request on LaunchScreen but have no idea where to put the code. Thanks In Advance, Kaaseter 回答1: As you wrote, LaunchScreen is there before your app is ready and it implies that you can't execute your code in this time. To achieve something similar, copy & paste
