Excel VBA Run-time error '424': Object Required when trying to copy TextBox

由 左心房为你撑大大i 提交于 2020-01-01 03:25:08
问题 I'm attempting to copy the contents of a text box from one workbook to another. I have no problem copying cell values from the first workbook to the 2nd, but I get an object required error when I attempt to copy the text box. This macro is being run from the workbook containing the data I want copied. Using Excel 2007 Code: Sub UploadData() Dim xlo As New Excel.Application Dim xlw As New Excel.Workbook Set xlw = xlo.Workbooks.Open("c:\myworkbook.xlsx") xlo.Worksheets(1).Cells(2, 1) = Range(

FFTW vs. OpenCV cvDFT

由 南楼画角 提交于 2019-12-31 22:37:19
问题 Can I expect a speedup when using FFTW (http://www.fftw.org/) instead of OpenCV's cvDFT (http://goo.gl/YCHj0)? My program's runtime is heavily determined by the application of inverse and forward DFT and I am thinking about using FFTW instead of OpenCV cvDFT. IIRC FFTW does some kind of "runtime compilation" whereas cvDFT is a simple FFT implementation, so I guess it could speed up my processing a bit. So before I am trying it out by myself, I thought to ask in here in case anyone stumbled

Algorithm with O(n log n) time and O(1) space complexity vs O(n) time and O(n) space complexity

由 廉价感情. 提交于 2019-12-31 12:50:57
问题 I am curious to know which algorithm is better : Algorithm with O(n log n) time and O(1) space complexity Algorithm with O(n) time and O(n) space complexity Most of the algorithm which are solved in O(n long n) time and constant space can be solved in O(n) time by paying penalty in terms of space. Which algorithm is better ? How do I decide between these two parameters ? Example : Array Pair Sum Can be solved in O(n logn) time by sorting Can be solved using hash maps in O(n) time but with O(n

Arcgis runtime sdk .net 二次开发

由 ▼魔方 西西 提交于 2019-12-31 11:24:59
前段时间研究了下 arcgis runtime sdk .net 二次开发··这里做个笔记 runtime版本为100.6 基于WPF 开发 命名空间引入 xmlns:esri="http://schemas.esri.com/arcgis/runtime/2013" 基本只用到了mapview这个控件和相关的对象，下边把默认的背景网格去了，改了背景色,mapview的map对象是依赖属，性支持绑定的，可直接绑定 <esri:MapView x:Name="MyMapView" Map="{Binding Path=MainMap}"> <esri:MapView.BackgroundGrid> <esri:BackgroundGrid Color="yellow" IsVisible="False"/> </esri:MapView.BackgroundGrid> </esri:MapView> 可直接在nuget上安装arcgis runtime ,直接安装arcgis的 WPF开发包会自动安装runtime的包，默认为开发者授权，是有开发者水印的，可以申请为arcgis开发者，有lite版授权，可以去掉水印， 这个lite版授权有很多限制,比如不能加载本地地图。下边代码为使用开发者授权license代码 //使用lite版license //去掉水印 var res =

java注解和反射的结合使用

由 柔情痞子 提交于 2019-12-31 08:05:28
首先反射注解，那么保留策略必须是Runtime，也就是@Retention(RetentionPolicy.RUNTIME) ①定义一个注解类 @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.FIELD}) public @interface MyAnnotation { int value(); } ②在定义一个类使用注解类 public class MyBean { @MyAnnotation(20) private int value; @Override public String toString() { return String.valueOf(value); } } ③在main方法里面反射注解 public static void main(String[] args) { try { Field field = MyBean.class.getDeclaredField("value");//获取成员变量value field.setAccessible(true);//将value设置成可访问的 if(field.isAnnotationPresent(MyAnnotation.class)){//判断成员变量是否有注解 MyAnnotation myAnnotation = field

Can Java Runtime.exec another java program that uses stdin?

由 走远了吗. 提交于 2019-12-31 05:01:42
问题 I have run into an issue where , when using Java Runtime to run another java program, the program freezes because the other program requires stdin . There is a problem with handling the stdin after executing another java program with Runtime exec() . Here is sample code that I can't get to work. Is this even possible? import java.util.*; import java.io.*; public class ExecNoGobble { public static void main(String args[]) { if (args.length < 1) { System.out.println("USAGE: java ExecNoGobble

Which method to detect run mode of php script is more reliable?

由 雨燕双飞 提交于 2019-12-31 04:27:08
问题 I now to ways to detect weather php script runs in cli or web server mode: if (defined('STDIN')) or: if (isset($argc)) Do they equally reliable or one of them is more ? 回答1: Neither. Check the value returned from php_sapi_name() . 回答2: $_SERVER['REQUEST_METHOD'] won't be set, due to the lack of a HTTP request. I think defined( 'STDIN' ) or isset( $argc ) are reliable too, though. If it was up to me, I'd probably go with the defined( 'STDIN' ), as I can imagine someone accidentally setting a

Setting enum value at runtime in C#

由 此生再无相见时 提交于 2019-12-30 17:22:49
问题 Is there any way that I can change enum values at run-time? e.g I have following type enum MyType { TypeOne, //=5 at runtime TypeTwo //=3 at runtime } I want at runtime set 5 to TypeOne and 3 to TypeTwo . 回答1: Just refer to MSDN help HERE An enumeration type (also named an enumeration or an enum) provides an efficient way to define a set of named integral constants that may be assigned to a variable. Also HERE In the Robust Programming Section - Just as with any constant, all references to
