New to PostgreSql - requires assistance

Good day

I am a VB6 programmer with plenty of MS Access Databasis and applications and would like to start using PostGreSql instead.

I installed PostGreSql, pgAdmin4 and drivers - not sure if everything required is now installed. 

I successfullly created a database and table in PostgreSql, and now want to start implimenting it in VB6.

My big problem now is the connection to the database  from VB6.  I tried the following connection strings:

  conUsers.ConnectionString = "Driver={PostGreSql Unicode(X64)};SERVER=localhost;port=5432;DATBASE=WinMedAngela;UID=postgres;PWD=Goslow22%;CommandTimeOut=300;"

  conUsers.ConnectionString = "Driver={PostgreSql ANSI(x64)};SERVER=localhost;port=5432;DATBASE=WinMedAngela;UID=postgres;PWD=Goslow22%;CommandTimeOut=300;"

  conUsers.ConnectionString = "Driver={PostgreSql};SERVER=localhost;port=5432;DATBASE=WinMedAngela;UID=postgres;PWD=Goslow22%;CommandTimeOut=300;"

... which caused error "Data Source Name not found and no default driver specified".

It seems that there is a problem with the driver.

Could you please assist me with this issue.

Kind regards
