Unfortunately, it is not compatible with autohotkey_L unicode.
It currently only works with autohotkey basic and autohotkey_L (ansi).
Can anyone help change this code so that it will be compatible with autohotkey_L (unicode)?
I am sure many people can use it and it will help encourage the adoption of autohotkey_L (unicode).
Here is an example of how simple it is to connect to a mysql database and execute a query using this include.
#Include mysql.ahk
; Connect to the sql database at the top of the program
db := dbConnect("hostname","userid","password","databasename")
sql =
(
SELECT request,
user,
priority
FROM table1
WHERE Status = 'Pending'
ORDER BY requestdate DESC
)
result := dbQuery(db, sql)
This is the mysql.ahk include file:
;============================================================
; mysql.ahk
;
; Provides a set of functions to connect and query a mysql database
;============================================================
;============================================================
; The fileinstall command does 2 things.
; 1. When this ahk program is compiled into an exe, fileinstall indicates which files should be embedded inside the exe.
; 2. When the exe version of the program is run, fileinstall extracts the embedded file to the specified folder.
;
; note: #include files are automatically embedded at compile time, so you don't need to use fileinstall for them.
