I love my Delphi 4 but at the same time I see the need to talk to windows .net
This is a recompiled dll that I found on sourceforge.net/projects/delphinet/ (DelphiNet03.zip) by some nice people that fund the dll from some were.
The real answer is to make this dll so that fits into Delphi as true Delphi code, and not a dll clip on. So we can make objects that use dot net in Delphi. Because I’m not an assembly freak, I’m freaking out a little with a wee sweek for help!
1/ How do I link the asm code with the data info at the bottom of this code. Can some one show me which calls to look for to make this link to data.
2/ I need to find the beginning of all the procedures and functions, but I cannot find a ‘RET’ statement. And what line is the beginning statement in this code.
3/ How do I identify were the jump statements go to, put them into Delphi format
In this code it looks I can do:-
jle 402890h \1000:00402854 7e3a
add [eax], al \1000:00402856 0000
……………………………………………..

Is that a correct conversion.
I think a
xrefs first: 1000:004021d1 number : 1
is the best to follow
4/ I need a good reference on 8086 up assembly code that I can print out and get to learn properly.
I found this asm decomplier of http://www.cronos.cc/ that is so similar to
Delphi that it only needs a little more convertion to get it into Delphi asm I think.
It’s only taken me 3 hours to get the file into TMemo and to write a few lines to chop the line over in a stream and reload the memo.
