I think these information can be helpfull for everyone
Thx decard!

1. How to Use AsmEdit

You have three options:

i. Standard AsmEdit control, from DLL (easiest Wink): search this forum for latest AsmEdit control in DLL (may require updating control's core to latest files, but don't worry about it), then in your program: load this DLL, call RegisterAsmEditClass function, and from now you can use AsmEdit in a similar way you use standard Edit (create window of 'ASMEDIT' class).

ii. Standard AsmEdit control, compiled with your project (recommended): get latest FASMW, all files from \source\ide directory (but from \source\ide\fasmw copy only asmedit.inc and asmedit.ash). Then include asmedit.ash and asmedit.inc in your source. Add this code in the beginning (initialization part):

Code:
invoke LoadCursor,0,IDC_IBEAM
mov [wc.hCursor],eax
mov [wc.style],CS_GLOBALCLASS+CS_DBLCLKS
mov [wc.lpfnWndProc],AsmEdit
mov eax,[hinstance]
mov [wc.hInstance],eax
mov [wc.cbWndExtra],4
xor eax,eax
mov [wc.hbrBackground],eax
mov [wc.cbClsExtra],eax
mov [wc.lpszMenuName],eax
mov [wc.lpszClassName],_asmedit_class
invoke RegisterClass,wc


This will register asmedit. Don't forget to define _asmedit_class string.
Now you can use this conrol just like in first paragraph.

iii. AsmEdit control from Fresh: more difficult, as this control is more complex (has margin, supports bookmarks, themes...). You have to proceed like in ii., but there are more things to do when initializing AsmEdit: you have to provide bookmark and other icons (AEM_SETICONS message), set theme (AEM_SETTHEME)... and it requires Fresh macro library (uglobal macro).

Of sourse I didn't described every detail, if you will have any problems then feel free to ask.

Proably in each case you would want to set some different font after creating AsmEdit control. I'd recommend starting with ii., you have FASMW source as an example.

I verified we need these other

_asmedit_class db 'ASMEDIT',0
asmedit_font dd 0
whell_scroll_lines dd 3
case_table rb 100h

Problem: when using AEM_GETLINE
I don't know why...with

invoke SendMessage, [hAsmEditwin], AEM_GETLINE, dword 6, Buff

if the source line .6 is 'test', in Buff I find 'est'.
I verified: line 499 in 'BLOCKS.INC'
lea esi,[esi+SEGMENT_HEADER_LENGTH+edx]
edx is set '1'....

solution? what's wrong?

How to obtain the total line number of the source code loaded in AsmEdit?

You can't do it directly (currently there's no such message). You have to:

1. Store current position (AEM_GETPOS).
2. go to last line (AEM_SETPOS with caretLine and caretSelectionLine set to -1).
3. Read current position (AEM_GETPOS again). Then read aepos.caretLine - it will contain last line number.
4. Restore previous position by calling AEM_SETPOS again with position obtained in 1).
