Hi, the following error occurs, when I wnat to compile my soucce:

ASM-File:
__________________________________________
.386
.MODEL FLAT, STDCALL
OPTION CASEMAP:NONE

INCLUDE Include\WINDOWS.INC
INCLUDE Include\KERNEL32.INC
INCLUDE Include\USER32.INC
INCLUDE Include\MASM32.INC
INCLUDELIB Library\KERNEL32.LIB
INCLUDELIB Library\USER32.LIB
INCLUDELIB Library\MASM32.LIB

.const
dateiname EQU + 8
string EQU + 6

.code
_SchreibeDaten PROC PUBLIC
PUSH EBP
MOV EBP, ESP

INVOKE MessageBox, NULL, ADDR dateiname, ADDR dateiname, NULL
RET 1
_SchreibeDaten ENDP
END
???????????????????????????????????????????????????

CPP-File:
_____________________________________________________
extern NEAR int SchreibeDaten(char c_dateiname, char c_string);
SchreibeDaten("Huhu", "huhuagain");
??????????????????????????????????????????????????????
In the option I add the obj-File fomr the asm-proc.

What could be wrong ?
:confused: :stupid:

You need some serious help - and you need to read the FAQ section of this board.
linkage of asm+C/C++ - read the FAQ.

furthermore, you don't really seem to know wtf you're doing - "ret 1" ? having your proc after "start:", and "end start" in something that is presumably meant to be linked in as a utility function, not the program body? Using german names for procs and data?

I'd say you're not ready for assembly.

I don't really like cdecl , use stdcall

.386

.model flat,stdcall

option casemap:none



include /masm32/include/user32.inc

includelib /masm32/lib/user32.lib

.code

start:



OPTION PROLOGUE:NONE

OPTION EPILOGUE:NONE

_SchreibeDaten proc

invoke MessageBox, 0, [esp+4],[esp+8],0

leave

retn 4*2

_SchreibeDaten endp

OPTION PROLOGUE:PROLOGUEDEF

OPTION EPILOGUE:EPILOGUEDEF

end start

Hope it works.

I just wunder wich library or dll I have to include.
I already seek aorung, but nothing found.

I did this for 4 years ago and everithing worked fine, but now I have some problems.

Thanks for helping !

One unresolved function, what can I do ? :confused:

btw this won't work either:

The chars should be char pointers (char*).

No you don't have to, just change it to extern "C" and add *'s to the chars.

.486

.model flat, stdcall

.code

public SchreibeDaten

SchreibeDaten proc pMsg:dword, pTitle:dword

    invoke  MessageBox, NULL, pMsg, pTitle, NULL

    ret

end

extern "C"

{

    void __stdcall SchreibeDaten(const char *pMessage, const char *pTitle);

}
