C++ Builder - Web Services (SOAP)

[@musandlala7991]

Great tutorial, simple and straight to the point

[@hartcons]

We had a c++ builder 5 application where a soap connection suddenly stopped working recently when the customer upgraded their server. this example got us going again using c++ builder xe6. thx!

[@vclexamples]

Thanks Rabi. I would create more tutorials but I have a lack of ideas at the moment :) Regarding book, try C++ Builder 5 Developers Guide. Even if this book is for much older version of BCB it is really good and comes with a lots of examples. Can be downloaded online for free.

To be honest, i haven't try to use json yet with C++ Builder... Regarding .pas files; C++ Builder supports using .pas files but i'm not sure from what version exactly. All you need is to go to projects/add files... and add your .pas file. Try and compile the project and if it shows no errors then your C++ Builder supports .pas files. When .pas is compiled it's .hpp file is generated. Include that .hpp file into your cpp file (#include...) and then you can use all the functions from .pas file.

Thanks a lot, very useful!

[@giuliuploader]

how about web service for database, is the same? i suppose the only difference would be making sql statement in place of the add you made?

I need some help in regards to this. I am struggling with the following: __property TByteDynArray WSQData1 = { index=(IS_OPTN | IS_NLBL), read=FWSQData1, write=SetWSQData1, stored = WSQData1_Specified }; I write to the TByteDynArray without any issues. I have even saved the array to file and the file is readable. When I submit this structure to the webserver, the array is empty. Any idea why this will happen? Regards,

Hello, How can I get the connected client Ip address to SOAP server. IP address must be on HTTP header, I searched about that but dont find any property on TInvokableClass. Do you have any idea about this?

[@giuliuploader]

i have a question! you have after this tutorial 2 programs, don't you? because a webservice is created in order to acces from one computer to another, so yu can press the button that add 2 number in a different machine? Great tutorials, thanks..

[@vclexamples]

Yes. Web service is one application and other application is nothing but web service client that uses it's services (functions).

Hi, Can web server send message to client or clients any time without client request? Thanks for tutorial..

[@vclexamples]

It's a client-server communication based on HTTP (TCP/IP), so the answer is NO.

[@ersinozdmr]

I need this; A web server can send indications to specific 1 or 2 clients and clients send request to the web server. Is it possible to make communication using XML like this? If it is not possible, should the client periodically check(send request) to see the changes made by the server? Thanks for yor help.

[@vclexamples]

Client should periodically check if there are any changes on the server side by sending request. That is how TCP (web http) works. If your server would be UDP based than it would be no problem to send data from server to client without request since UDP is connection-less protocol, and UDP would simply throw packages to the clients.
