Overview
Modern computers (servers and desktop computers) are equipped with 64-bit operating systems.
The main difference between a "32-bit" and a "64-bit" system is as follows: in "64-bit", the applications and the system no longer have memory allocation limitations.
In "32-bit" configurations the operating system is limited to 4 GB, while in "64-bit", there is nearly no limit (18 billion GB).
To help you develop 64-bit sites and applications, WINDEV and WEBDEV propose:
  • A framework available in 32 bits and in 64 bits
  • The WEBDEV Application Server available in 32 bits and in 64 bits
  • The HFSQL Client/Server server available in 32 bits and in 64 bits. For more details, see HFSQL Client/Server.
How to?
WINDEVWindows

To create a 64-bit application

  1. Develop your 64-bit application. A 32-bit application can be changed into a 64-bit application.
  2. Deploy your application.
WEBDEV - Server code

To install a WEBDEV site on a 64-bit server

  1. Install a 64-bit WEBDEV Application Server on a 64-bit Web server.
  2. Develop and deploy your WEBDEV site on the Web server.
Remark: A site compiled in 64-bit can be used with a 32-bit or 64-bit server. A 64-bit server can only display 64-bit sites. If the site was not compiled with the "64-bit" option, an error will be displayed when the site is started.
