Code Editor Line number?

[caraveiro]

Hi Buddies!

I want to make an application with a Edit Control to comparing text, but I want to color the dif. lines; It seems easy using a richedit control.

But I have no idea how to display the line number on the left side of the rows (line numbers same way that the code editor does).

Maybe having TWO edit controls wrapped: one for showing line number and the other to show the text. What do you think? 

Regards!

Are you talking about this?

and... yes, it seems that's not easy! 


But it seem a lot easier than what I was pretending to smoke,  some grass that goes by the name of InkEdit:

Thank you!

richedit controls and smoking grass probably don't go together well   :lol:

I would extend the left margin of the control and use that area to display the line numbers:

EDIT: handle leak fixed

Wow, wow!

Thank you.

;)

I someone need it; here are the best richedit reference I'd found.

Bravo!

[aurel]

Hello
is there a compiled 32 bit version of this program?
I simply don't know how to compile this example because i don't know assembler
yes shame on me   
thanks in advance

[jj2007]

Yep, shame on you, Aurel

Here is a quickie for you. But it won't help much, because there is no source around. Btw which proggie do you mean, the one by caraveiro or qWord's example?

[aurel]

Yes shame  on me ..

hI jj , well i am not sure , one which show line numbers in richedit margin

edit; yes that one from qWord do you can compile it ?

edit2; jj ..do you have line numbers in your MasMbasic editor ,sorry i forgot all that things...

[jj2007]

edit2; jj ..do you have line numbers in your MasMbasic editor ,sorry i forgot all that things...

Kind of, yes: If text is selected, then you get in the upper right corner, for example:
L1200 C3+4 73d 49 6E 69 74h meaning
line 1200
column 3 + 4 characters selected
73d is the decimal code of the first selected character
49 6E 69 74h are the hex codes of the four selected characters (Init)



If no text is selected, you get the absolute line number plus the line inside the current proc or macro:

I'm confused.
What is it you are looking for exactly?

[aurel]

Hello
Yes looking confusing but not .
I asking is there anyone who can compile this above source code to 32bit exe  and zip it that i can try how work.
I simply don't have a clue how to do that , or i must download somewhere masm32 ?
i download Jwasm but there is no any include in that sourceforge pack.

[aurel]

jj ...well as i can remember and see it  looks that you dont have it,i dont know how is that possible
because you have all that interesting things in it ,even i don't get it what is what ,
sorry but i am too stupid ,or to slow ..

[jj2007]

Apparently Aurel wants something like this, from qWord's example:



Which is fine but not that useful if the editor jumps to the error line anyway:



@Aurel: Step by step installation instructions are here. Re "is there anyone who can compile this above source code to 32bit exe", no, because there is no source code...

I can't see what you are referring to.  Which program is  "this"  program?
