 |

Hello everybody,
Using a TImageList my app can have access to bitmaps that r stored
internaly. Is there a way to do so with wmf files?
Thank you very much for your time

Not. TImageList work with bitmaps only.
But you may easy convert your wmf to bmp and from bmp to wmf

From bmp to wmf is not possible. At least, not losslessly and if you are
able to in the first place, it is very difficult.

yes - incorporate the WMF _file_ into your application as a resource, then load
the resource as a stream.
eg: you have a file called MyFile.wmf.
create a files called images.rc; it contains:
MyFile WMF "MyFile.wmf"
compile images.rc to images.res using brcc32.exe.
in your Delphi app:
{$R images.res}
....
// you will need to check exact syntax - this is off the top of my head:
Res:= TResourceStream.Create(hInstance, 'MyFile');
Res.Position := 0;
MyMetaFile.LoadFromStream(Res);
cheers,
Mat

g'day Johnnix,
re:

("Resource MyFIle not found") exception when the following line is executed:
Res:= TResourceStream.Create(hInstance, MyFile' ,RT_RCDATA);

{$DEFINE DEBUG ON}
now you need to debug, though not exactly in the traditional way.
first, check that MyFile _IS_ a resource within your application.
next, check the spelling, and the capitalization (i doubt that MyFIle is present).
third, if all else fails, then define MyFile as a resource number in your .rc
file, and use the TResourceStream.CreateID constructor.
cheers,
Mat
