I'm currently designing a software application for work and I'm planning on installing the application on several computers. However the application will not be finished and there would be incremental updates from time to time I would have to do. Is there a way to update my software that is installed on multiple computer without having to go from one computer to the next?

I am not much familiar about this but have some queries.
I have installed MySQL database in a desktop and using it for creating a web application in my workplace. After the app gets created, I want all the computers to have an access to the database in the desktop I have used as it has all the DB tables.
One more thing I want to know that as the application needs application server to run it, is there any way I can achieve it in this scenario.
Thanks.
I inherited a heavily-customized Magento EE project that has been through multiple stages of disaster. The production database has never been pulled down to lower environments in the roughly two years of the project. It appears the production database has no triggers defined, but all the lower databases (dev, test, etc), do have triggers, which is what you'd expect in a Magento EE project.
At this point I'm not even sure how the application is still running on production. I'm loading a triggerless mysqldump that I took from prod into another environment now to see if the database actually works.
Has anybody ever seen this before? How would this even happen? Maybe the project started out on CE and then was upgraded to EE and the upgrade failed partially? I'm at a loss.
As far as I can tell, this was caused by the upgrade path from CD to EE, and I guess the previous consultants hacked the upgrade process to not create triggers, or it failed and they didn't notice. Triggers are only necessary if you're reindexing via cron job, not after save, so the app still runs ok.
i have been working on a project using Visual Studio 2015 along with vb.net and mysql. I deployed my application using ClickOnce to my company server then installed on all the computers in my company. It is working fine. Recently, i have it installed on three new computers which has the exact same os and specs with the existing computers, however, the application installed on the three new computers showed a very significant difference in performance comparing to the existing computers, it is much slower in the new computers.
I have checked through
the networks
the connection to MySql database
the memory it consumes
the .net framework version
but it is all exactly the same with the existing computers. does anyone have any idea what might be the cause? Or anyway to troubleshoot this problem?
Just add timers, stopwatches, etc to instrumented builds. In fact, in an application of any size I build-in, from the off, at least a skeletal diagnostic system with a display window and stopwatches that can be used to time specific bits of code - typically database queries. With that in place, it's simple to add specifics to produce instrumented builds to drill down to any problems that only occur on end-users' machines. You can also download DbgView from Microsoft and use that in conjunction with Trace statements in your code.
I am sure there is a solution out there, but have not been able to locate anything that achieves the exact specifications I need.
I am looking for a web based script/application that can convert a MS Access database to text/csv any form of readable file.
The reason I need it to be web based is that our management currently uses an access database software package to create and track user data. They export a subset of the tables required for user registration (via a mdb type saved as a different extension). This is currently processed through the software providers website. The problem being that the software provider no longer provides developmental support for the registration forms.
We do not wish to change the entire foundation of the Access database and if at all possible I just want to provide a solution that opens and converts the uploaded file (mdb type) and converts it to a text schema, or anything really that will enable us to dynamically generate web based forms for the tables uploaded.
Well you certainly could cobble together something yourself.
However the hosted web site would for all practical purpose have to be running something like ASP.net and ALSO support the reading of mdb/accdDB files.
I mean most web sites that support the JET/ACE database engine in 99% of the same cases also support .net code.
If you're running your own web server and especially asp.net then this should be no problem.
However you don't mention if this is your own web server or a hosted one? And you don't mention what kind of hosting you have?
Remember your web site runs on a computer. That computer could be a Mac computer, a windows computer or Linux. And you simply install software + programs onto that computer like a desktop computer.
If that computer is Linux based then you not going to be able to install say your vb.net software on that web site. So what kind of computer and OS your web site is running on will DETERMINE what kind of software it will run.
If your site is currently an asp.net hosted site and they support reading of Access files (has support for JET/ACE) then I don't see why a bit of vb.net (or c#) application could not be written with little effort to have that file uploaded and then the contents read.
I think before go looking for some software to do such a conversion I would FIRST find out and figure out what computer platform your web site is running on now. You THEN need to find out if that computer hosting the web site has support for JET (now called ACE) data engine.
It is a walk in the walk in the park to have some code open + read the mdb or accDB file and send that data to the web sites SQL server. However you can ONLY do this if your site in question has support for the JET/ACE database engine. (or you have your own server and you are ALLOWED to install the JET/ACE engine).
So a solution program (off the self) does exist then AGAIN 9 out of 10 times such a solution will REQUIRE that the JET/ACE engine be installed on your hosted web site.
So just keep in mind that like windows or Mac computer or even a tablet computer – the web server is EXACTLY the SAME in regards to WHAT software will run on that web site.
So without knowing what kind of web hosting you have then it becomes rather hard to suggest a working solution that will be able to run + be installed on your web site since we don't even know what kind of software can be installed on your web site now?
If you current web hosting does not allow the JET/ACE data engine to be installed it is VERY unlikely that EVEN if you found some software that does a conversion for you then such software will NOT install on your existing web site.
Any competent asp.net developer should with quite ease allow one to select a local mdb file, upload to server and then have web code open up the mdb file and pull out table data to sql server.
The only real thing stopping this process is as noted what kind of web server you have and what kind of software it will run.
Keep in mind the issue is OFTEN what kind of software you can install on the web server.
Just about every web provider allows managed code (c# or vb.net) code to be up-loaded on the server to be run. However installing NON managed code like the JET/ACE database engine is a VERY VERY different matter.
Starting point:
You need a web provider that supports the JET/ACE database engine or you need to be running your own web server that allows you to install the JET/ACE database engine.
Furthermore how would the software you install know the table names in Access and also know the table names in SQL server and also where to send the data?
At the end of the day all of the software bits and parts rather common exist if you have your own ISS server with asp.net. And if your provider is using asp.net AND ALSO supports JET/ACE then AGAIN you have all the software required.
As such then your code can use ftp or even HTTP to upload that file. All of these features are built into the .net framework assuming your web hosting provider allows asp.net + JET/ACE.
It is cumbersome to update different kinds of software one by one. In my case,
For the Ubuntu Linux OS, I periodically do apt-get update and apt-get upgrade or apt-get dist-upgrade (this part can be automated).
For Ruby language, I have to do particular things to upgrade.
For Ruby libraries (gem), I have to periodically do gem update or gem update --system.
For JQuery library, I have to periodically check its website and download the latest version.
And so on.
I can write a script to automatically do these things, but it would be nice if there were a cross-platform unified established way where a user can just register all the software they want to be automatically updated, and a software will periodically check the relevant websites for updates and notice the user and/or automatically do the update when there is such update.
Does such technology exist? If not, what will be a promising line for such technology in the future? I have a feeling that it could be done by using something like RSS feed, where software developers will publish feeds whenever they update a software, and a specific reader takes care of the update process.
No. And it never will. This kind of luxury comes with a price called "gated community". But then it does not apply to ALL software...
