Hello all,
I have à windev project with the HF/classic database. Now i'm thinking about making à mobile app for à tablet/phone. I have never worked with Windev Mobile. What is the best way to connect to my windev project database wich is on à local pc or à network server.
I want to acces the database to view it and to add à picture or something. |

Hi Sammy
the best way is to create a web service. It can be soap or rest depending on your preferences (I prefer rest). If the mobile device connect only 'in house' a local webservice is enough, and it can access the HF classic DB...
If the mobile device has to connect when outside of the lan, then you either need a URL to redirect to your local server, or a replicated set of data on a web server
Best regards |

Sammy,
I agree with Fabrice about using a webservice (or webpage) to do the database handling.
Using this extra layer gives you a lot of options to parse the data, do logging, etc before it goes into the database.
This way you can also "trace" more or less what the tablets are doing, without the need for the actual device.
And whenever your db structure changes, this middleware can "jhide" these chagnes from your tablet. Which prevents you from the need to update the talets as well, whenever the database changes. Very handy is certain situations.
That said: you can also choose to convert the HF to a HFCS and connect from the tablet directly to the db. Personally I would do that only in very simple situations. Like in yours where everything is in house? |

Sammy,
you can make a webservice with WINdev.
To run the service (on a webserver with IIS of apache) you need a webdev ENGINE (bunch of DLLs and a administration tool)/
You can download it for free an use up to 10 concurrent users. If you need more then you can get a 299 euro license from pcsoft. (but still don't need webdev itself). |
