Hello!
Could you help me please?
I have a small icon - only 125 bytes size. And I don't want to use the external file 'filename.ico', I would like just write a text in my source.asm file - I mean the data definition.

I want something like this:

Code:
icon main_icon,icon_data,myarray

myarray db 0,0,1,0,1,0,0,0,2,0,1,0,1,0,103,0,0,0,22,0,0,0,137,80,78
db 71,13,10,26,10,0,0,0,13,73,72,68,82,0,0,1,0,0,0,1,0,1,3,0,0,0,102
db 188,58,37,0,0,0,3,80,76,84,69,214,58,242,88,100,57,17,0,0,0,31,73
db 68,65,84,120,1,237,193,1,1,0,0,8,2,160,254,175,238,70,41,48,0,0,0
db 0,0,0,0,0,207,45,33,0,0,1,132,95,242,171,0,0,0,0,73,69,78,68,174
db 66,96,130
    


I think I should modify the icon macro but I don't have enough knowledge for this. Could anyone please help?

macro icon group,[label,icon_file]
{ common local count
count = 0
forward local data,size,position
label dd RVA data,size,0,0
virtual at 0
file icon_file:6,16
load size dword from 8
load position dword from 12
end virtual
data file icon_file:position,size
count = count+1
common local header
align 4
group dd RVA header,6+count*14,0,0
header dw 0,1,count
forward
file icon_file:6,12
dw label#.resid
common
align 4 }

This line includes the data in the program

It can be replaced with a construction of the following type

Code:
if icon_file eqtype ""
   data file icon_file:position,size
end if
    

//--------------
Code:
    label dd RVA data,size,0,0 
    virtual at 0
     file icon_file:6,16
     load size dword from 8
     load position dword from 12
    end virtual
    

This piece reads the location of the icon data and their length from the file header
It can be replaced with . . .
Code:
if icon_file eqtype ""
    label dd RVA data,size,0,0 
    virtual at 0
     file icon_file:14,8
     load size dword from 0
     load position dword from 4
    end virtual
else
    label dd RVA icon_file,icon_file.#sizeof,0,0 
end if
    


//-----------------
Code:
    file icon_file:6,12
    

This line adds a description of the icon in the resources
It can be replaced with . . .
Code:
if icon_file eqtype ""
  file icon_file:6,12
else
  dq icon_file#.header_data
  dd icon_file#.sizeof
end if
    


//------------------------
And then you can pass a label to your data array instead of the file name (or file name), and you should define two values for the array
Code:
  myarray db ... (any icon data) ...
  .sizeof = $ - myarray
  .header_data = (Icon header values, 8-byte)

Thanks so much!

Forgive me please, I didn't say that my icon data bytes are the whole content of the icon file.
Therefore .sizeof = $ - myarray - 22.

And .header_data are 8 bytes beginning from the 6th byte of the array, I figured out, great!

align 4
group dd RVA header,20,0,0
header dw 0,1,1
db 0,0,2,0,1,0,1,0,103,0,0,0
