Hello I'm working on a messagebox program but running into linking errors. Here is the code: I am using MASM from WinASM. It does not make any difference if using the full path to the library.

CODE

includelib user32.lib
includelib kernel32.lib
include user32.inc
include kernel32.inc

.MODEL small, stdcall

.STACK 100H
.DATA

Text1 DB �'Hello World!', 0
� � �Text2 DB �'Message Title', 0

.386 �
.CODE

main �PROC

mov �ax,@data �; Get the address of the data segment
mov �ds,ax �; Set the DS segment

push 0
push offset Text1
push offset Text2
push 0

call MessageBox

main ENDP
END � �main

at first you made a win32 project with dos template, which uses dos version of linker.

create new empty win32 project, and paste there this code:

CODE

.386 �
.MODEL flat, stdcall

includelib user32.lib
includelib kernel32.lib
include user32.inc
include kernel32.inc

.DATA

Text1 DB �'Hello World!', 0
� � Text2 DB �'Message Title', 0

.CODE

main �PROC

push 0
push offset Text1
push offset Text2
push 0

call MessageBox

ret

main ENDP
END � �main

++++++++++++++++

also, if you see while building the errors kinda "can not find file" check if you did all written in Programming Quick Start
