PureBasic Forums - English

1. ... of discussions, where some "experts" reply to messages which they did never read, and/or post stuff that is completely off-topic in the respective thread. This happens often here on the forum. When it's a thread that was started by me, I feel the need to set things right. This is nothing but a waste of time and energy from my point of view.
2. ... of running against walls in the heads of other people. And I'm not going to offer my commitment, my ideas, my knowledge and my experience as if they were sour beer.

My main suggestion was/is, not to use '0' everywhere in an example where it is technically possible, but to use meaningful named constants instead.

#DatabaseQueryFail = 0

SetDatabaseString(Databasehandle, 0, "1")
SetDatabaseString(Databasehandle, 1, "1")

If DatabaseQuery(Databasehandle), "UPDATE db_addresses SET locked  = ? WHERE recordid = ?") <> #DatabaseQueryFail
  ; "Do something here
Else  ; Query failed, constant is now obvious too so we get here
  Debug DatabaseError()  
EndIf

This was also the reason for me, to start the following thread in the PB forum: viewtopic.php?f=7&t=45842

Mijikai wrote:I would also 'force' EnableExplicit

In the beginning i never used it and though i dont need it... obviously a mistake
Now i always use it (i also use End btw.).

I think it would be a good thing to have it only as check box option in the compiler settings that by default is always on.

This doesn't have got much to do with what I wrote in the first post of this thread.
Feel free to start a discussion about that in a separate thread, but don't hijack this one

Denis wrote:+1
EnableExplicit by default will be good.

Maybe someone is interested in the fact, that I (deliberately!) never wrote that ...
This is a different discussion. Feel free to discuss that in your own thread, but don'*t hijack this one

Little John wrote:Another improvement of example codes would be, to make them ready for usage with EnableExplicit. So I actually would write the respective examle code like this:

Code: Select all

Prototype.i ProtoMessageBoxW(Window.i, Body.p-unicode, Title.p-unicode, Flags.i = 0)
Define MsgBox.ProtoMessageBoxW
#Library = 0

If OpenLibrary(#Library, "User32.dll")
   MsgBox = GetFunction(#Library, "MessageBoxW")
   MsgBox(0, "Hello", "World")
EndIf

There is no EnableExplicit at all in that code. But the trick is:
That code runs with EnableExplicit on or off, so it is always usable!

In contrast, the following code (similiar to that one in the help)

Code: Select all

Prototype.i ProtoMessageBoxW(Window.i, Body.p-unicode, Title.p-unicode, Flags.i = 0)
#Library = 0

If OpenLibrary(#Library, "User32.dll")
   MsgBox.ProtoMessageBoxW = GetFunction(#Library, "MessageBoxW")
   MsgBox(0, "Hello", "World")
EndIf

only runs with EnableExplicit off, but not with EnableExplicit on.

Code: Select all

EnableExplicit

or

Code: Select all

DisableExplicit

?
Extremely redundant request...

I never requested that, and this has nothing got to do with what I wrote in my original post here.
However, it's old news hat some people like to post offtopic stuff in other people's threads ...

I didn't say that it was you who hijacked my thread. I just wanted to make things clear.
