lplpBlaBlaBla?

[DC]

Code Select Expand

invoke  VerQueryValue, addr pBlock, addr szVer, addr lpTranslate, addr bLen
puts a pointer in lpTranslate which is suposed to be a of TYPE:

Code Select Expand

_LANGANDCODEPAGE    struct
    wLanguage   WORD    ?
    wCodePage   WORD    ?
_LANGANDCODEPAGE    ends
LANGANDCODEPAGE typedef _LANGANDCODEPAGE
ptrLANGANDCODEPAGE typedef ptr LANGANDCODEPAGE
I get the pointer but am unable to access the data, what am I missing?
I've tried ..... lpTranslate.wLanguage, ptr lpTranslate.wLanguage, ...
thanx for any help,
DC

I'm gettin' closer with this...

Code Select Expand

        assume  edi:ptr LANGANDCODEPAGE
        mov     edi, lpTranslate
        invoke  wsprintf, addr SubBlock, addr szFrmt, [edi].wLanguage, [edi].wCodePage
I might even get it shortly...
wish me luck,
DC

still stump't...
this is an attempt to translate the example for "VerQueryValue":

Code Select Expand

// Structure used to store enumerated languages and code pages.

HRESULT hr;

struct LANGANDCODEPAGE {
  WORD wLanguage;
  WORD wCodePage;
} *lpTranslate;

// Read the list of languages and code pages.

VerQueryValue(pBlock,
              TEXT("\\VarFileInfo\\Translation"),
              (LPVOID*)&lpTranslate,
              &cbTranslate);

// Read the file description for each language and code page.

for( i=0; i < (cbTranslate/sizeof(struct LANGANDCODEPAGE)); i++ )
{
  hr = StringCchPrintf(SubBlock, 50,
            TEXT("\\StringFileInfo\\%04x%04x\\FileDescription"),
            lpTranslate[i].wLanguage,
            lpTranslate[i].wCodePage);
if (FAILED(hr))
{
// TODO: write error handler.
}

  // Retrieve file description for language and code page "i".
  VerQueryValue(pBlock,
                SubBlock,
                &lpBuffer,
                &dwBytes);
}
here's what I have so far...

AFAICT, this should work.

My personal preference is not using ASSUME, and referring to [edi].LANGANDCODEPAD.wLanguage where edi is a pointer to the structure.

You may want to check to see if wsprintf is the culprit here. If it's expecting words and ML is extending them to DWORDs (or vice-versa) you won't get any correct output.
Try extending them yourself to DWORDs and telling wsprintf to expect DWORDs.

that was it!!!!!
Thanx zooba. that seems like an odd solution to this delema.
I would've thought MS would be more carefull with all there type'ing and what not...
thanx again,
DC

[DC]

sorry MS....
I guess I should've looked closer...
my bad,
DC

[DC]

cleaned up
thanx zooba for the tips, I like that style of reference better too
