cant I just replace ml with uasm?

[daydreamer]

must I change to some unicode as standard to replace
db "this is ascii string",0

dw "this is a unicode string",0 ?
dw "一二三四五六七八九十百千万",0
so line 2 and 3 kind of text can be mixed in api calls that use WCHAR as standard?

[daydreamer]

I got a strange bug,I call a proc in a different source file and it breaks code,so it suddenly exits
wrong epilog setting?,but if I insert
jmp main
Label:


ret
main:
call label
it works

Can you sure a bit more of a complete example?

Hi daydreamer,

I think you should define unicode strings like this:

dw "t", "h", "i", "s", " ", "i", "s", " ", "a", " ", "u", "n", "i", "c", "o", "d", "e", " ", "s", "t", "r", "i", "n", "g", 0
dw "一", "二", "三", "四", "五", "六", "七", "八", "九", "十", "百", "千", "万", 0

From the regression test pack in UASM, we have the following test-case/example file:

You should be able to use dw that way to declare WCHAR strings, and with OPTION LITERALS:ON + L prefix you can directly insert them into INVOKEs.

option casemap : none
option frame : auto; generate SEH - compatible prologues and epilogues
option win64 : 11; init shadow space, reserve stack at PROC level

Posting code that doesn't assemble in a very old stale thread is a bad habit, daydreamer

include \masm32\MasmBasic\MasmBasic.inc         ; download
  Init
  uMsgBox 0, "一二三四五六七八九十百千万", "This is Unicode, and it works:", MB_OK

I put lots of pushes after label and pops before ret and it works,could been the problem,main loop uses most registers and call proc
