Code to create Persistent Field components associated with TDataSet

由 走远了吗. 提交于 2019-12-24 03:08:19
问题 Looking for some example code illustrating how to create at runtime TField Components associated with a dataset. In the IDE, if you plop down a dataset component, right-clicking brings up the fields editor that provides this functionality at design time. Have not been able to find code showing how to do it at runtime. TIA 回答1: Each field type has a Create function that you pass the DataSet to that creates a field of that type and adds it to the Fields. From the help for DB.TStringField.Create

High resolution timer/code run time -> overhead?

由 ￡可爱￡侵袭症＋ 提交于 2019-12-24 03:07:54
问题 I'm trying to find my Code run time using a high resolution timer, I've noticed that the timer has inconsistent results and I would like to find out why this is. I found this article How do you test running time of VBA code? and have implemented the top answer, I tried using it to find the run time of several functions and noticed that the results changed fairly drastically. To see if this was a fault of the timer, i made a function where I just started and stopped the timer. Public Sub test

set_magic_quotes_runtime()和get_magic_quotes_runtime()

由 假装没事ソ 提交于 2019-12-24 00:47:39
set_magic_quotes_runtime()和get_magic_quotes_runtime() 是针对数据库 get_magic_quotes_gpc() 是针对GPC, Get/Post/Cookie 来自http://www.5iphp.com/zh-hans/content/325.html 来自http://hi.baidu.com/samyucn/blog/item/df14cb3590a03c46251f14da.html 1、PHP中set_magic_quotes_runtime()函数的作用： 此函数来修改PHP.ini文件中的 magic_quotes_runtime 变量的状态，如果想获得magic_quotes_runtime 变量的状态用get_magic_quotes_runtime这个函数如果返回0表示本功能被关闭，如果返回1表示本功能已经开启。 magic_quotes_runtime的功能是当它被开启的时候所有外部引入的数据库资料或者文件等等都会自动转为含有反斜线溢出字符的资料。比如： 用户向数据库提交的数据中含有\" '这些符号的时候它就会在这些符号的前面自动加上"\"转义符。 这个属性在PHP4以前的版本都是默认关闭的，PHP4.0以后的版本如果程序要用到将它关闭的时候直接写成set_magic_quotes_runtime(0

magic_quotes_gpc和magic_quotes_runtime的区别和用法详解

由 ▼魔方 西西 提交于 2019-12-24 00:47:23
当你的数据中有一些 " ' 这样的字符要写入到数据库里面，又想不被过滤掉的时候，它就很有用，会在这些字符前 自动 加上，如 中国地大物博"哈哈" 中国\地大物博"哈哈" 可以使用 set_maginc_quotes_runtime(0) 关闭掉，当然你也可以直接在php.ini中设置。 get_magic_quotes_runtime() 取得 PHP 环境变量 magic_quotes_runtime 的值。 magic_quotes_gpc 为 on，它主要是对所有的 GET 、 POST 和 COOKIE 数据自动运行 addslashes() 。不要对已经被 magic_quotes_gpc 转义过的字符串使用 addslashes()，因为这样会导致双层转义。遇到这种情况时可以使用函数 get_magic_quotes_gpc() 进行检测。 两者不同 set_magic_quotes_runtime() 可以让程序员在代码中动态开启或关闭 magic_quotes_runtime ， set_magic_quotes_runtime(1) 表示开启， set_magic_quotes_runtime(0) 则表示关闭。当 set_magic_quotes_runtime(1) 时，从数据库或通过fread之类的函数读取的文本，将自动对 ’ “ 和自动加上反斜杠进行转义

How can Java execute batch file in separate process tree

由 試著忘記壹切 提交于 2019-12-24 00:44:15
问题 I'm writing my Java app a update mechnism. I create a windows batch file,exit my program and the batch file continues to delete my Jar, copy the new one from a remote location, start the jar. My problem: deletion + copy works, BUT - the application won't start. I think the problem is that I don't know how to make Java to execute batch file in separate process tree. when running this: Runtime.getRuntime() I open a child process. So my question - How can Java execute batch file in separate

Hiding the navigation bar immediately on app launch

由 你。 提交于 2019-12-24 00:40:07
问题 Based on the following code snippets, I was able to hide the status bar right when the app launches , but not the navigation bar (the bar consisting of the back, home, and task manager buttons) since it hides later after MainActivity's thread finishes loading up : Here's the manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="dpark.sample2"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher"

Compile IL code at runtime using .NET 3.5 and C# from file

由 左心房为你撑大大i 提交于 2019-12-24 00:38:39
问题 I would like to take a file that is an IL file, and at run time compile it back to an exe. Right now I can use process.start to fire off the command line with parameters (ilasm.exe) but I would like to automate this process from a C# service I will create. Is there a way to do this with reflection and reflection.emit? While this works: string rawText = File.ReadAllText(string.Format("c:\\temp\\{0}.il", Utility.GetAppSetting("baseName")), Encoding.ASCII); rawText = rawText.Replace("[--STRIP--]
