I am trying to do a DLL, but keep getting this odd message. Any guesses?
I am using RaDASM

Creating library VxD_DLL.lib and object VxD_DLL.exp
VxD_DLL.dll : warning LNK4086: entrypoint "__VxD_DLL" is not __stdcall with 12 bytes of arguments; image may not run
LINK : error LNK2001: unresolved external symbol __VxD_DLL
VxD_DLL.dll : fatal error LNK1120: 1 unresolved externals

Make error(s) occured.

Project options are as follows:
assemble: 3,O,$B\ML.EXE /c /coff /Cp /nologo /I"$I",2

The source code is as follows:
EXPORTS Get_Ring0_Handle

.model flat,stdcall
option casemap:none

include \masm32\include\windows.inc
include \masm32\include\user32.inc
include \masm32\include\kernel32.inc

includelib \masm32\lib\user32.lib
includelib \masm32\lib\kernel32.lib

Kernel32_Lib db "KERNEL32", 0H
FunctionName db "OpenVxDHandle", 0H

Lib_Handle dd 0H
Proc_Address dd 0H
Ring0_Handle dd 0H
Ring3_Handle dd 0H


VxD_DLL proc hInstDLL:HINSTANCE, reason:DWORD, reserved1:DWORD
mov eax, TRUE
VxD_DLL Endp

Get_Ring0_Handle proc hRing3:DWORD

mov eax, hRing3
mov , eax

;load the kernel32 lib

mov eax,
cmp eax, 0H
; jnz Lib_Loaded ;lib already loaded

invoke LoadLibrary, addr Kernel32_Lib
mov , eax

invoke GetProcAddress, , addr FunctionName

mov eax,
mov , eax

invoke FreeLibrary,

mov eax,


Get_Ring0_Handle Endp

By the way it has the same message/error for the DLL tutorial as well.

I don't think you need that initial VxD_DLL label at the start. Maybe.

Oh, sorry. I put that there in the post so everyone could tell where the file started.

"VxD_DLL:" is not really in the source file.

OK, I found the problem.

I had downloaded the 98DDK, and copied the ML.exe from that package into masm32\bin in order to assemble vxd's. Turns out this version doesnt like the syntax or something about any other type of source file other than a vxd file.

So now my delima is how do I change the project options to assemble with the following:

for vxd's -> use ML_vxd.exe
for all others -> ML_org.exe

I tried changing masm.ini but it didnt make any difference, whenever I look at project options, it shows ML. Niether ML_org, or ML_vxd show up for either type of project.

Any help would be appreciated.

Well you know...

I forgot to change the project file for my existing projects to call the appropriate ML'r. DOH!!

All is well now.
