From: Dirk (Belgium) on 6 Aug 2010 05:10 Karl, That other program also get data from SAP by calling a WebService to SAP. So, because that other program is capable to do webservice calling, I was thinking to provide my data on the same way to other programs. Dirk.

From: Dirk (Belgium) on 6 Aug 2010 05:12 Richard, No, my program can have DBF tables or ADS tables. But I don't want that the other program access the tables directly because on that moment I do not have any control anymore on the contents of the records.

From: Nick Friend on 6 Aug 2010 06:09 Dirk, Possible route... Create a web service that the other program (let's call it Program A) can call and which will receive the ID information of the data Program A wants to get hold of. This "request" gets written into a database on the web server. Your own program (B) polls this database periodically to see if there are any requests... when there are, Program B posts up the info to another table on the web server. Meanwhile program A polls periodically to see when the info is available, and simply downloads it when it's there. Obviously there's going to be more involved, but that could be a skeleton set-up. That could all be done in PHP (for example using NuSoap which is dead easy) or as someone else suggested, as a DotNet add-on. You don't need to write a web server, just have any old web server that can host your service programs - if it was in something like PHP it could be virtually any commercial hosting service.

From: Dirk (Belgium) on 6 Aug 2010 06:52 Nick, You have right, but there is just one problem: You write the following: "Create a web service...." So, my question again: How to create a web service ??? Dirk, Belgium TO ALL, What is so difficult to understand ? It is just like a ftp-program. There is a client-side and a server-side. You have a FTP-Client and a FTP-Server. Now, I have a Web-Client and have to make a Web-Server. If someone is telling that IIS is a WebServer, that I can understand. BUT, can he explain also how IIS is looking into a DBF-file ? So, it is just that part of the program I want to write in VO or Vulcan.

Hi Dirk, So yes you want to write a web service (which will be hosted by a web server that you don't write), and it should be really easy to do in Vulcan. Probably Willie has some code. I've only created web services in C#, and it's really easy with the VS tools. Are your DBF files also used by other apps? If not this seems like the perfect opportunity to move to SQL. -- Ginny Caughey www.wasteworks.com |
