[WM20] Barcode reading

Startbeitrag von Sivaprakash am 27.08.2016 05:08


WM 20

Need to read barcode, ask to enter quantity, save these info in a server db connected via wifi. I understand that it requires a Webdev application in the server, so that WM application can communicate with the server.

Is this is the way to do this work, or other methods are available ?

Yes you can work with trghe webdev application server and host a webservice on that . The webservice would do the saving to db etc,.

But depending on specifications, if it is a LAN you are working on a windev mob can do the saving as well and windev will be able to get the values from the db. so no need for application server then.

Thanks Allard.

My idea is to do this work from a mobile, not from a computer, that the mobile can read the barcode, provide a space to enter the quantities [like POS, but in a miniature way] get a return value from the server.

Is that a mobile could be connected to a server using LAN ? I thought wifi is the only way.

you -CAN- connect directly to a HFCS DB from WM20...

However, what you are describing looks like a stock application, generally used in a warehouse. And WIFIcoverage is therefore also generally spotty, to say the least.

So, if you are in a case where wifi coverage may not be perfect and where you could loose the connection, then you not oly need a webservice, but you need first to save your data in a local DB, then, WHEN and IF you have a connection, transfer it to your server DB.

So, if all my previous assumptions are correct, what you need is a replicated system (you can check out WXReplication on my web site for that)

Best regards

Fabrice Harari,

I'm using your wxreplication in this project, to transfer between data between branches. Searching a simple solution to transfer data captured through mobile to the server where adequate wifi connectivity will be provided.

I'll try out to connect the HFSQL Server from mobile and do the things.
