2 different results fro the same code!

[Jean-Luc Arnaud]

Hi all,

I'm used to test some codes in little test apps before using these codes
in main apps.

Today, I'm facing a very strange issue.

I'm opening a ".ico" file using:

  If SourceFile.NameExtensionMBS="ico" Then
    p=Picture.Open(SourceFile)

    ...

In my little test app, after the second line, p (defined as a global
property of type "Picture) has a depth property of 0, Graphics Nil,
ImageCount 4 And

    p=p.BestRepresentation(MyCanvas.Width,MyCanvas.Height,1)

returns the expected result, that is, the icon matching the closest
properties of MyCanvas.

Now, the same code with the same p property, in my main project, returns
a p object with a depth property to 32, Graphics not nil, ImageCount to 0

and a p.BestRepresentation returning always a 16x16 icon, of course with
the same SourceFile.

The p property is not instantiated, a break point on the second line in
both projects shows a nil p property.

I don't understand what's happening, so any idea, help, suggestion,
exorcism is welcome.

TIA

In addition, I just tested to open the .ico file SourceFile in a
MemoryBlock in both projects, the content is the same!

So, in the first project, Picture.Open(SourceFile) returns a Picture
containing 4 icons, as expected (16x16, 32x32, 48x48 and 256x256).
In the second, it returns only the first icon, that is the 16x16 one.

Any explanation?

Thanks

JL Arnaud

I assume you are using the same version of Xojo for both projects?

I´m staying at 2017R1.1 right now because in 2017R2 a picture that appears correct in an iOS projekt in R1.1 is rendered HUGE in R2.

Might have nothing to do with your problem though.
