[01 Oct 2009] Resource loaded?

Hi,

I need to free the resources by my own. Is there a way to know if a resource (i.e. a brush) is actually loaded at the specified id?

Regards, Paolo.

What IDs are you using? Are you using number or new Hollywood 4.0 style IDs? (i.e. passing NIL as number and getting the return value), i.e.

Code: Select all

my_brush = LoadBrush(Nil, "test.iff")
DisplayBrush(my_brush, 0, 0)

I'm using the old style, providing explicit IDs.

Hi Andreas, I'm using the old style, providing explicit IDs.
So you want to check if a certain explicit ID contains a brush? There's no convenient way for this, I'm afraid, but you can use a little work around, i.e.

Code: Select all

/* returns True if specified id is a brush */
Function p_CheckBrush(id)

Local brush_there = True

ExitOnError(False)
GetAttribute(#BRUSH, id, #ATTRWIDTH)
If GetLastError() <> 0 Then brush_there = False
ExitOnError(True)
Return(brush_there)

EndFunction
This should do the job. It's a little bit awkward because it disables/enables the automatic error handler but it should do what you want :)

It's only useful if you've a larger project. Using hard-coded IDs can get quite bothersome in this case so you might want to use the new IDs. For smaller projects I find it easier to use hard-coded IDs like 1,2,3,4 :)
