I'm sorry I missed updates on this thread. I'm still having problems. Windows 2k SP4 with SSE3 CPU.
I gets NULL-pointer somehow - it tries to write to it. It doesn't matter what I write to the dec,bin,hex,exp - it still crashes the moment I press <Enter>. maybe you have jmp [0] somewhere or call [0], the zero can be also a register lik jmp eax (where eax is zero). EDIT: OK, I did some debugging and I can see that your are not taking proper care of your threads. I know I had problems with my Conversion Dialog also  I can see, when I'm pressing <Enter> the program sends a SendMessage, but it gets in an infinite loop where this wierd thing happens:
after 5484 instructions, USER32 calls!!! to your program and this is where it goes: Code: push ebp mov ebp,esp push ebx edi cmp [ebp+12],111h ;273 je label1 cmp [ebp+12],10h ;16 je label2 cmp [ebp+12],110h ;272 je label3 xor eax,eax jmp label4 label1: cmp [ebp+16],4000001h je label5 cmp [ebp+16],4000002h je label6 cmp [ebp+16],4000003h je label7 jmp label4 label5: jmp label4 label6: jmp label4 label7: jmp label4 label3: ;... ;324 bytes of code for dialog I think ;... label4: pop edi ebx ret Then it returns to USER32 and does this a few times. Final call to CallWindowProcA gets a zero pointer inside USER32 in 36 instructions. Let me quote OllyDbg here 
Code: PUSH 0 PUSH ESI PUSH [DWORD EBP+18] PUSH [DWORD EBP+14] PUSH EDI PUSH [DWORD EBP+C] CALL [DWORD 77E6DB38] ;This address in dump is full of zeros many ;kilobytes up and down ...where ebp=6FD20h and stack is...

decard: I know your solution is better, but now I need fast solution...after FASMWNG version 1.00 I think I'll optimize everything
Madis731: I notice the problem you said in debugging code too.....now I think the problem can be in Fasm...when it compile resource...I'll do some test.....first i'll use a normal window instead of the dialog.... BtW....why debugging with no simbol, when you can ask the source?
here you are ... decard & Madid: are you on MSN???

take a look at the new file posted
I don't know why whe the win (that will be for the code completition) I have problem....other win disappear....???? Madis: try now the WinConverter... Last edited by Crukko on 02 Mar 2006, 10:21; edited 1 time in total |

Don't know what causes the crash, but yes, I'm in MSN too...check the little icon called "msn" in my profile
Maybe try: Code: proc WinConverterDialogProc hWnd,msg,wParam,lParam pusha ;Preserve all possible registers just to be safe ;..... I pushed only ebx, edi because they where the absolute minimum for my app popa Try figuring out threads because SendMessage triggers a thread and if it doesn't end before the next message is sent your stack will go nuts and possibly you get all kinds of results 
Very strange: When I set a new origin in OllyDbg (somewhere in the message loop) it runs again and I think even flawlessly. I've put "1-4" there and then when I checked it again - the others were updated. But then - when I "X" it, the whole program gets terminated |

finally..the first working 'code completition' in FasmWNG!!!!!
1) open a Fasm source 2) try to type something...if the window appear press CTRL + RETURN
3) if you want you can search next/previous by CTRL + UP/DOWN only labels and proc (recognized) are searchable... next steps are: - more to recognize
decard: if you want we can work on your Fresh Last edited by Crukko on 02 Mar 2006, 10:20; edited 1 time in total |

OK. Is there any part you would like to code? Or are you familiar with debugging API?

Crukko 22 Feb 2006, 14:47
decard:
1. where I can find the list of part to be coded ?
2. what did you mean for 'debugging API' ? Windows or Fresh one? |

22 Feb 2006, 14:47 |

decard 22 Feb 2006, 15:20
1. source\doc\todo.txt (but there are just "general ones").
2. I mean Windows debugging API :Wink: Fresh debugger is based upon them. |

Code: 4. List of code completion symbols have to be stored in some file. When user loads project, he will be able to use CC function without recompiling sources. This list should be also generated in background, but I don't have an idea how exactly it will work I'm working on for FasmWNG....It will be also disponible for Fresh
ok? |

Crukko 02 Mar 2006, 10:26
So...This time things are going to be better
First of all Open a source!!! Then... Try: 1. CC (CTRL+UP/CTRL+DOWN/CTRL+RETURN) 2. Go To Line (CTRL + G): use labels and line number
3. Tabbing File: if you want to Open an include file go onto the line, than CTRL + T... I hink that's all
Next step: compiling.....
