 |
|
How do I use shellExecute to execute parameters that contain utf8 characters ?
It looks like it's garbled.
for example:
| Code: | local str="/c echo 中国 & pause"
--str=utf8ToAnsi(str)
shellExecute("cmd.exe",str)

Answer1:
For this you need shellExecuteW
Don't know about "中国". With "ęσąśłżźćń" works OK.
| Code: | function shellExecuteW(command, parameters)
if ShellExecuteW_MemoryStream_Buffer==nil then
ShellExecuteW_MemoryStream_Buffer = createMemoryStream()
ShellExecuteW_MemoryStream_Buffer.Size = 4096
end
local addr = ShellExecuteW_MemoryStream_Buffer.Memory
executeCodeLocalEx('RtlFillMemory', addr, 4096, 0)
writeStringLocal(addr+0x000, 'open', true)
writeStringLocal(addr+0x100, command, true)
writeStringLocal(addr+0x200, parameters, true)
return executeCodeLocalEx('ShellExecuteW', 0, addr+0x000, addr+0x100, addr+0x200, 0, 1)
end
local str = "/c echo ęσąśłżźćń & pause"
--shellExecute("cmd.exe", str)
shellExecuteW("cmd.exe", str) |
By the way, could you check this one: https://forum.cheatengine.org/viewtopic.php?p=5756662#5756662

I can't pass the code test above
32-bit Error: executeCodeLocalEx is currently not supported on the 32-bit build
64-bit Error: CE process crash

Yes. I expected this.

I didn't test it on other OSes. Maybe this one:
| Code: | function shellExecuteW(command, parameters)
if ShellExecuteW_MemoryStream_Buffer==nil then
ShellExecuteW_MemoryStream_Buffer = createMemoryStream()
ShellExecuteW_MemoryStream_Buffer.Size = 4096
end
local addr = ShellExecuteW_MemoryStream_Buffer.Memory
--executeCodeLocalEx('RtlFillMemory', addr, 4096, 0)
for i=1,512 do
writeQwordLocal(addr+(i-1)*8,0)
end
writeStringLocal(addr+0x000, 'open', true)
writeStringLocal(addr+0x100, command, true)
writeStringLocal(addr+0x200, parameters, true)
return executeCodeLocalEx('ShellExecuteW', 0, addr+0x000, addr+0x100, addr+0x200, 0, 1)
end
local str = "/c echo ęσąśłżźćń & pause"
--shellExecute("cmd.exe", str)
shellExecuteW("cmd.exe", str)
|
Edit:
fill with zeros (writeQwordLocal in an loop)

hello, mgr.inz.Player, Are you a developer of CE ? If you are，I hope you can update the CE source code. shellExecute has a bug. The bug is located in LuaHandler.pas. I hope you can fix it.
Although I can modify your source code and compile it, I still hope to use the official version, and I am willing to support your products all the time.
| Code: | function shellExecute(L: PLua_State): integer; cdecl;
var
pcount: integer;
command: string;
parameters: string;
folder: string;
showcommand: integer;
begin
pcount:=lua_gettop(L);
if pcount>=1 then
begin
command:=UTF8ToWinCP(lua_tostring(L, -pcount));
if pcount>=2 then
parameters:=UTF8ToWinCP(lua_tostring(L, -pcount+1))
else
parameters:='';
if pcount>=3 then
folder:=UTF8ToWinCP(lua_tostring(L, -pcount+2))
else
folder:='';
if pcount>=4 then
showcommand:=lua_tointeger(L, -pcount+3)
else
showcommand:=SW_NORMAL;
shellapi.shellexecute(0,'open',pchar(command),pchar(parameters),pchar(folder),showcommand);
end;
lua_pop(L, lua_gettop(L));
result:=0;
end; |
| Code: | | shellExecute('cmd.exe',"/c echo σσσσσσσ & pause") |

I'm not. He is link
I think you should open an issue here:
| Code: | | https://github.com/cheat-engine/cheat-engine/issues |
Your patch do not break backward compatibility?
e.g. many people use shellExecute to open links:
| Code: | | shellExecute('http://forum.cheatengine.org/viewtopic.php?t=552928') |
Probably they use for other things (not only URL nor cmd.exe).
