i have used vb6 application with oracle client 11. but at the run exe, i got the below error:
-2147467259/Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation.
Provider is unable to function until these components are installed.

This is a duplicate question and the cause could be a number of different issues. This is likely due to the wrong client version being installed on your machine, and/or it is related to a known issue involving a security update for specific versions of windows. Please see the following Questions on Stack Overflow.

Here is the Mircosoft support article on the patch issue: https://support.microsoft.com/en-us/help/3126587/ms16-014-description-of-the-security-update-for-windows-vista-windows
Most likely you installed the 64-bit version of Oracle Client 11. VB6 binaries are always 32-but, thus you must install the 32-bit version of Oracle Client.
In case you need both, 32 and 64 bit versions one one machine follow this instruction: BadImageFormatException. This will occur when running in 64 bit mode with the 32 bit Oracle client components installed
According to your error messages you use the drivers from Microsoft. These drivers are deprecated for ages, you should prefer the drivers from Oracle.
