GUISQL.au3 UDF library

[HansH]

This UDF library has some basic functions for connecting and querying SQL databases.

The UDF library can be found here : http://www.autoitscript.com/fileman/users/HansH/GUISQL.au3

If you have remarks or improvements, let me know, so I can adapt it

and do the documentation according the UDF standards

Underneath a small example how to use this.

GUIDelete()
Exit

; This is a general COM error handler
Func _COMErrHandler() 
   $sCOMErrMsg=hex($oCOMError.number,8) & ":" & $oCOMError.description
   SetError(1)              ; something to check for when this function returns 
Endfunc

Mmm, of course the library has nothing to do with a GUI, so I will adapt the name

later on. Any suggestions for an other name are welcome.
