UpdateResource is not updating

[georgek01]

Hello!

I'm trying to update a string resource in an EXE. The code looks as follows:

Code Select Expand


invoke BeginUpdateResource,addr ListBuffer,FALSE
.if eax == NULL
   invoke ErrMsg,hMain,1,101,NULL
   mov eax,1
   ret 
.endif

mov hResource,eax

invoke MultiByteToWideChar,CP_ACP,MB_PRECOMPOSED,addr ListBuffer,sizeof ListBuffer,addr buffer,sizeof buffer

invoke UpdateResource,hResource,RT_STRING,addr szContent,LANG_ENGLISH,addr buffer,sizeof buffer
.if eax == 0
   invoke ErrMsg,hMain,2,101,NULL
   mov eax,1
   ret 
.endif

invoke EndUpdateResource,hResource,FALSE
.if eax == 0
   invoke ErrMsg,hMain,6,101,NULL
   mov eax,1
   ret 
.endif


No errors occur and the resource is not updated. Any ideas perhaps why?

GetLastError value doesnt change?

This is the error display procedure.

Code Select Expand


ErrMsg proc hW:HWND, icode:DWORD, itype:DWORD, phead:DWORD

local lbuffer:DWORD
local mbuffer[256]:BYTE
local dwError:DWORD

.if itype == 0
invoke GetLastError
.else
invoke GetLastError
.endif

mov dwError,eax

lea eax, [lbuffer]
invoke FormatMessage,FORMAT_MESSAGE_ALLOCATE_BUFFER + FORMAT_MESSAGE_FROM_SYSTEM,0,[dwError],LANG_NEUTRAL,eax,0,0
invoke wsprintf,addr mbuffer,addr szErrorFormat,[dwError],[lbuffer],icode
invoke MessageBox,hW,addr mbuffer,addr szApp,MB_ICONERROR+MB_OK
invoke LocalFree,[lbuffer]

xor eax, eax
ret
ErrMsg endp


If an error occurs, invoke ErrMsg,hMain,6,101,NULL calls the procedure that then displays the appropriate error message.

At all check points, eax contains the required return value (either !=NULL or !=0).

invoke UpdateResource,hResource,RT_STRING,addr szContent,LANG_ENGLISH,addr buffer,sizeof buffer

Sry, if it doesn't help, and I don't remember when and what,
coz some months went by since I played with updating resources.
But try SUBLANG_ENGLISH_US instead of LANG_ENGLISH.
