Natif Informix Connector for WINDEV and WEBDEV

Available only with this kind of connection

Overview

WINDEV and WEBDEV propose an optional Native Connector to Informix (also called Native Access to Informix). This Native Connector allows you to access an Informix database from a WLanguage program without using any external driver.

Benefits of using Native Informix Connector:

HReadxxx functions (HReadNext, HModify, etc.) can be used on Informix databases. This means that an Informix database and an HFSQL database can be handled with the same commands. Porting an existing application to external databases is simplified.
The RAD allows you to generate the code with the Hxxx functions (HReadNext, ...) or with the SQLxxx functions.
Direct access to an Informix database with no intermediate layer: MDAC, OLE DB and ODBC are useless.
WDMAP (the data viewer) can be used on your Informix databases (via the 32-bit client library).
The HFSQL Control Center can be used on your Informix databases (CC30HF.exe for the 32-bit client libraries and CC30HF64.exe for the 64-bit client libraries). This allows you to perform queries directly and to view the Informix data.
The setup is straightforward: No OLE DB or ODBC layer required on the user computer.
All versions of Informix databases are supported
etc.

The use of this Native Connector is highly recommended when developing Client/Server applications (that access Informix databases) with WINDEV or WEBDEV. Feel free to contact us for any additional information.

Caution:

This version of the Native Informix Connector works with WINDEV and WEBDEV SaaS.
This version of the Native Informix Connector does not operate with the following products: Informix Standard Edition (SE), Informix OnLine and Informix C-ISAM.

Required configuration

Conditions for using Native Informix Connector

In 32-bit:

Informix client layer 3.34.0.11061 (version checked by our services) must be installed.
The ICLIT09B.DLL DLL (version checked by our services) must be accessible:
- from the development computer.
- from the deployment computer.

In 64-bit:

Informix client library 4.10.00.15364 (version tested by our services) installed.
The ICLIT09B.DLL DLL (version checked by our services) must be accessible:
- from the development computer.
- from the deployment computer.

The ICLIT09B.DLL DLL is sought by default. If this DLL is not available:

Create a "WDIFMX.INI" file in the Windows directory (C:\WINDOWS for example).
Add the following information into the "WDIFMX.INI" file:

[CLIENT]
DRIVER=<DLL name>

where <DLL name> corresponds to the full path of the Informix DLL. This DLL can also correspond to the ODBC driver used to access Informix.

Required files

The following files are required to use Native Informix Connector:

ICLIT09B.DLL (version checked by our services): This DLL is installed by the client library of Informix. See the license agreement of Informix for more details about the distribution conditions of this DLL.
wd300ifmx.dll: Required for the Native Connector to an Informix database in 32-bit mode. This file is supplied with Native Connector for Informix.
wd300ifmx64.dll: Required for the Native Connector to an Informix database in 64-bit mode. This file is supplied with Native Connector for Informix.

Use

Using Native Informix Connector in your WINDEV applications and WEBDEV sites

To use Informix natively, you must program:

with the "SQL" functions of WLanguage (see Programming with SQL functions).
with the "HFSQL" functions of WLanguage (see Programming with HFSQL functions).

Remarks:

For more details, see the specific features regarding the use of Native Informix Connector.
The "Automatically create the data files when they are opened" option ("Files" tab in the project description) is taken into account by the Native Informix Connector.
