Code Editor Line number?

[jj2007]

Aurel,
The solution posted by Xusinboy Bekchanov works but is limited to the first 32768 (apparently) lines, then it restarts at zero under certain idiosyncratic circumstances:


Actually, it's much buggier than that, but I don't want to indulge in details here. Line numbers are 20th Century

The PARAFORMAT2 struct is described here at M$ docs. Note that they mention the wNumbering member, but it's not listed in the PARAFORMAT2 STRUCT; you would have to go back to PARAFORMAT, but the link is broken (apparently, nobody has ever used this feature, otherwise people would have complained, right?). But you can find it here.

To illustrate the mess, attached a little testbed. Press + to increase the wNumbering value, - to decrease it (see the status bar). Values<0 and >=7 produce nonsense, but #5 and #6 look very, very nice. Ideal for a code editor, actually

Hello jj and others...of course
Well i am not master for this assembler stuff but i know very well how windows win32 api functions works.
First time when i see this qWord assembly code i have feeling that must work.
Hey jj , line numbers is not just 20c things they are very useful for me at last.
After downloading ...never using EasyCode IDE ..then VisualMasm - which looks very nice but always require Project
offering Visual Designer...what is not bad in general i download another one called SASM IDE..
and voila this small (not very small but looks to me simply enough). i use it to compile qWord program.
You can screenshot ...it work ...and much important ...work properly! 
, i will spend some time to explore more masm examples.
JJ ...maybe you ask yourself...what that freak cooking this time...????
answer is simple..
This time i will try to create standalone code editor with my new interpreter without need for scintilla.
Yes scintilla is great control ,and i like it a lot...but it is one more separate .dll which always require adjusting,etc..etc...
well ..i really talking too much ...but ahh
i am glad that this assembly code work !

Also i have a question.
Is this control subcassed in this qWord program?
thanks

[jj2007]

I don't think so. I can't tell you with certainty because I don't have the source.

[aurel]

well JJ , i really don't know about what source code you talking, source code is under qWord post in code box.
and that is all, another thing is , it looks to me that you simply don't like it
I always like someone else code if i find it useful...in this case it is
all best...

aurel,

Tread carefully here, this forum is not a free code ordering facility and giving lip to members who have tried to help you will get you kicked out of here like a rocket. If you want an editor written in assembler, feel free to write your own. First and last warning.

is there a compiled 32 bit version of this program?

hello admin
I just ask for help abut given example by qWord and nothing else.
I really cannot understand what i do wrong.
thanks

[jj2007]

@Mikl: Molto bello

@Aurel: I just realise that qWord's post does contain the full source. I had thought it was only a snippet... my apologies

So all you have to do is copy the source, paste it into a text file, name it RicheditLineNumbers.asm, and build it, either with \Masm32\qEditor.exe or with \Masm32\MasmBasic\Richmasm.exe in case you have that installed.

Ciao, jj2007!
ci ho provato (я старался...)

[aurel]

Hi jj
Yes it is complete example and probably only one we can find out there.
Yes i do that , i first install masm32 sdk on my win7_32bit computer then setting IDE options and as you can see
program is compiled and work perfectly.
You know that i don't have experience with asseblers and i don't want to bother Charles with asmosphere assembler.
all best...

[aurel]

Sorry i forgot ti say
thank Mikl_ for your 64bit version , i see code is different and because i don't know is that
WASM i found in your signature..
thanks
