trying to launch a macro when the value of a DDE range changes

问题 I'm a novice in VBA but still I need yo execute a macro every time the value of a range changes. The marco is already written but if someone can help me with this issue, I will be very grateful. Just as you know the changing range is a DDE link updating the range with a continuous flow Thxs for your help 回答1: I think you are referring to Excel, so this may help: automatically execute an Excel macro on a cell change 来源: https://stackoverflow.com/questions/2409060/trying-to-launch-a-macro-when

Excel live data counter (DDE Server)

▼魔方 西西 提交于 2021-01-29 12:14:46
问题 I'm using DDE server to import live data on excel on two columns, the data changes every second. What im currently doing is i have live data on Cell A1 and live data on Cell B1 on Cell C1 i have the following formula =A1=B1 Which is suppose to be true, but sometimes the result is false (as cell A1 doesn't match cell B1) I want to calculate how many times "false" is the result in C1 My problem is its a live data and changes almost every second, and my result should be accumulated. Does anyone

Limit solutions to a positive value using JiTCDDE

问题 I am using JiTCDDE to solve DDE's on a modified Oregantor model. The issue I am having is near the bifurcation point it will return negative values. While I know these are mathematically valid solutions, the Oregantor represents a chemical system. Hence, negative answers are not realistic to a real system. Is there a way to set up the code to return a minimum value for a variable when it is <=0. Below is the main part of the code I have so far. def P1(k): return( ((H*y(k))/(k01+H*y(k)+kl*H*H

Running an Excel macro when info is pushed through a DDE connection

我的梦境 提交于 2021-01-28 05:43:54
问题 I currently have an HMI that communicates with Excel through a DDE connection. If I update values in the HMI then the values are updated in the spreadsheet of Excel and vice versa. Which is exactly what I want. However, I created a VBA code that will also update values in the spreadsheet when values are changed in the HMI. This VBA code does not run though if I change the values through the HMI but will run if I manually change them in Excel. Is there something that I am not considering?

Create DDE server in python and send data continuously

问题 I am trying to write a DDE server in python which needs to send a continuously changing string to a program which is connected as a DDE client. The program which connects to a DDE server uses the following DDE settings to connect [Service: Orbitron, Topic: Tracking, Item: Tracking]. The program has to receive information that is sent by the DDE server in the following string format: "UP0 DN145000001 UMusb DMfm AZ040 EL005 SNNO SATELLITE". The content of this string changes approximately every

【红外DDE算法】聊聊红外图像增强算法的历史进程(第一回)

宽动态红外图像增强算法综述 回顾过去 带你回顾宽动态红外图像增强算法的历史进程,历来学者的一步步革命(新的算法框架提出),一步步改革(改进优化),从简单粗暴到细致全面。 正所谓是:改革没有完成时,只有进行时。没有完美的算法,也没有最好的算法,只有更好更优秀的算法。 展望未来 以现在看90年代的算法,那时候的算法是有点粗糙,但是正是在这一点点的积累上,才有了现在较之优秀完美的算法。 正所谓是:站在巨人的肩膀,我们看得更远,不积跬步无以至千里。 目录 为什么需要该算法? 摘要 主要的三类算法思路大致介绍 第一类:基于映射的宽动态图像增强算法 第二类:基于图像分层的宽动态图像增强算法 第三类:基于梯度域的宽动态图像增强算法 三类算法的对比与优缺点分析 1.关于为什么需要宽动态红外图像增强算法? 详见我之前的文章《数字细节增强算法的缘由与效果(我对FLIR文档详解)》 https://blog.csdn.net/hahahahhahha/article/details/102978112. 2.摘要: 从三类算法开始介绍,基于映射的宽动态图像增强算法,基于图像分层的宽动态图像增强算法,基于梯度域的宽动态图像增强算法。 3.主要的三类算法思路大致介绍 早期的算法(大概1999年之前),主要是基于映射的。实现简单,复杂度低,但是细节不够凸显。 为此,学者提出了基于图像分层的算法

Does DDE still matter? Which are the alternatives?

问题 I'm working on a stock exchange information platform and we are thinking in provide a link between our platform and home-made Excel files. The financial market is still bound to the old DDE server approach, now does it still matter today? Which are the alternatives to make automatic online data updates on Excel files, OLE DB queries? I wonder if anyone has any example of implementing an OLE DB provider in C# and .NET. Our API will be completely online and RESTful, there is any Web Services
