 |
|
I can set my program's version number in Project | Options
I can read the version number by right clicking on the EXE file and
selecting Properties.
Is there a way for a program to know its own version number?

Thanks, that was sufficient.
Whenever you want to do something, the first problem is: what function
to use? When you know the function name, the Help file can tell you
how to use it. In this case the Help file was n't helpful and I had to
search the internet for an example.
It is funny that the function requires the program name. Apparently it
is too stupid to know it. It can be obtained from argv (another
complication since only the main module knows argv), but fortunately
the program name is always the same, while the version number isn't.

No, it is generic. It can find the version for _other_ files, not just
the one that is currently running.

Ahh, but the user can change the file name.
You might be better using GetModuleFileName() to get the actual file
name. |

try this.........
Fn should be ParamStr(0); to get the current file version.
AnsiString BuildString(System::AnsiString Fn)
{
DWORD Handle;
DWORD Size;
bool error = false;
void *pBuffer;
AnsiString ret;
Size = GetFileVersionInfoSize(Fn.c_str(), &Handle);
if (Size)
{
pBuffer = new char [Size];
if (GetFileVersionInfo(Fn.c_str(),Handle, Size,pBuffer))
{
struct TRANSLATION { WORD langID; WORD charset; } translation;
VS_FIXEDFILEINFO * lpvi;
UINT iLen;
int n = VerQueryValue(pBuffer, "\\VarFileInfo\\Translation",
(void **)&lpvi, &iLen);
if (n != 0)
{
translation = *(TRANSLATION*)lpvi;
char szName[512];
wsprintf(szName, "\\StringFileInfo\\%04x%04x\\FileVersion",
translation.langID, translation.charset);
unsigned int buflen;
char *b;
if (VerQueryValue((LPVOID)pBuffer, szName, (void **)&b,&buflen))
{
ret = (AnsiString) b;
}
}
else error = true;
}
else error = true;
delete[] pBuffer;
}
else error = true;
if (error) ret = "N/A";
return ret;
