you missed the point of my request.
For your information, i have around 30 books of C, C++... :-P
As i wrote before, the loadstring works well...
works also)...
the problem is not there. because i can return strRes or re, the result
"--== Alain ==--" wrote:
Yes, but i would like to not use MFC for that.
if i use the following code, we know that local address is lost and
therefore can not be used :
extern "C" __declspec(dllexport) LPTSTR GetString(HMODULE hwnd_DLL,
int Index);
extern "C" __declspec(dllexport) LPTSTR GetString(HMODULE hwnd_DLL,
int Index)
{
static TCHAR *strRes;
int iError;
TCHAR re[2048] = {'\0'};
strRes=&re[0];
iError = ::LoadString(hwnd_DLL,Index, re, sizeof(re)/sizeof(re[0]));
return(strRes);
}
i also tried to pass it by reference, but nothing has changed.
i tried also to turn the function to send back a string (STL), but
nothing works also...
Alain,
You need to get decent C textbook and start reading it. You're
struggling with language features, which are explained in first couple
of chapters of any C programming tutorial.
Regarding GetString function, it doesn't make any sense. You don't need
to export anything to load string froum resources. You can call
LoadString from anywhere in your program with appropriate module handle.
If you want to have GetString anyway, then you need to pas to it memory
buffer to store string there. This buffer must stay valid after
GetString returns:
TCHAR szMsg[2048] = { 0 };
GetString(hInst, IDS_MESSAGE_ID, szMsg, 2048);
// use szMsg now..
GetString function should look like this:
extern "C" __declspec(dllexport) LPTSTR GetString(
HMODULE hDLL, int ID, LPTSTR psz, int nBufSize)
{
if(psz)
{
if(LoadString(hDLL, ID, psz, nBufSize))
return psz;
}
return NULL;
}
