Try this, you should get Devicename, port and the drivername of your default printer CPrintDialog dlg(FALSE); if (!dlg.GetDefaults()) AfxMessageBox(_T("You have no default printer!")); else { CString strDescription; strDescription.Format(_T("Your default printer is %s on %s using %s."), (LPCTSTR) dlg.GetDeviceName(), (LPCTSTR) dlg.GetPortName(), (LPCTSTR) dlg.GetDriverName()); AfxMessageBox(strDescription); } P-Man

To get the IP address, use gethostname() followed by gethostbyname(). charu123 wrote: Browser Information: Since more than one browser can be present, this question cannot be answered directly. One approach would be to call FindExecutable() with the name of some .html file. Then query that executable using GetFileVersionInfo() and VerQueryValue().

About Printer You already got the answer and about rest you can depend upon this api [GetSystemInfo]

Hi I am having some problem... please see this code and tell me whr I am going wrong. LPTSTR lptstrFilename; char buffer[BUF]="C:\\Program Files\\Internet Explorer\\iexplore.exe"; lptstrFilename = (char *) malloc( sizeof(BUF) ); strcpy(lptstrFilename,buffer); DWORD dwHandle=NULL; DWORD lpdwHandle= -1; DWORD dwLen=0; void *lpData; dwLen= GetFileVersionInfoSize(lptstrFilename,&lpdwHandle); lpData = malloc(dwLen); DWORD dwError = GetLastError(); BOOL bRet = GetFileVersionInfo(lptstrFilename,NULL,dwLen,&lpData); PUINT lplpBuffer; PUINT puLen; VerQueryValue(lpData, TEXT("\\VarFileInfo\\Translation"), &lpBuffer, &dwBytes); I am getting an error when i reach the VerQueryValue. Can u please point out the mistake. U get wht u Give

[charu123]

I am not able to implement GetAdaptersInfo becoz it is not recognizing some header files. Is there any other way i can implement it. Probably read from some file etc. Can u tell me how to get CPU speed. Thanks U get wht u Give

charu123 wrote: char buffer[BUF]="C:\\Program Files\\Internet Explorer\\iexplore.exe"; This will not work if IE has been moved/installed to a different location. Better to use FindExecutable(). Why copy buffer to lptstrFilename? That makes no sense. :confused: charu123 wrote: Can u please point out the mistake. Not unless you disclose what error you are receiving.

Functions do not have the ability or capacity to recognize anything compiler-related. Perhaps you meant that the compiler is unable to locate a particular header file. charu123 wrote: Can u tell me how to get CPU speed. There are several ways of doing this, some better than others. Here is a Delphi example (it's a trivial exercise to convert to C). You can also look in the registry at HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0. I'ved used the following before:

unsigned __int64 start, stop;
unsigned __int64 nCtr, nFreq, nCtrStop;
QueryPerformanceFrequency((LARGE_INTEGER *) &nFreq);

_asm _emit 0x0F
_asm _emit 0x31
_asm mov DWORD PTR start, eax
_asm mov DWORD PTR [start + 4], edx

QueryPerformanceCounter((LARGE_INTEGER *) &nCtrStop);

nCtrStop += nFreq;

do
{
QueryPerformanceCounter((LARGE_INTEGER *) &nCtr);
} while (nCtr < nCtrStop);

_asm _emit 0x0F
_asm _emit 0x31
_asm mov DWORD PTR stop, eax
_asm mov DWORD PTR [stop + 4], edx

// stop-start is speed in Hz
// divided by 1,000,000 is speed in MHz

hi david, I ma getting the following error " the instruction at a memory location reference memory at . the memory could not be written." Could u point out where I am going wrong. char b[1000],a[1000],file[1000]="trial.html"; char path[1000]="C:\\Documents and Settings\\bhoomika.WIPHP_DOMAIN\\Desktop"; //CString a; LPTSTR data; data=(char*)malloc(1000); VS_FIXEDFILEINFO *pFileInfo; UINT BufLen; FindExecutable(file,path,data); DWORD dwHandle, dwLen; dwLen = GetFileVersionInfoSize (data, &dwHandle); LPTSTR lpData; lpData=(char*)malloc(sizeof(BUF)); if (!GetFileVersionInfo (data, dwHandle, dwLen, lpData)) { free (lpData); lpData = NULL; AfxMessageBox ("VersionInfo: not found\n"); } if (!VerQueryValue(lpData,"\\",(LPVOID*) &pFileInfo,(PUINT) &BufLen)) { printf ("VersionInfo: not found\n"); } else { sprintf (a,"MajorVersion: %d", HIWORD(pFileInfo->dwProductVersionMS)); m_ctrlBrowser.SetWindowText(a); sprintf (b,"MinorVersion: %d\n",LOWORD(pFileInfo->wProductVersionMS)); } free(data); return TRUE; Thanks For all the help. U get wht u Give

charu123 wrote: lpData=(char*)malloc(sizeof(BUF)); I think this should be lpData=(char*)malloc(dwLen). charu123 wrote: sprintf (b,"MinorVersion: %d\n",LOWORD(pFileInfo->wProductVersionMS)); The compiler should have complained about this one as wProductVersionMS is not a valid member name. Other than that, and the lack of error checking, what you have should work. You do, however, seem to be confused as to when to use MFC and when not to. Unless there is no MFC equivalent for some Win32 function, it really makes no sense to mix the two. Here is a modified version of your code:

VS_FIXEDFILEINFO *pFileInfo;
LPCTSTR pszFile = "trial.html",
pszPath = "C:\\Documents and Settings\\bhoomika.WIPHP_DOMAIN\\Desktop";
CString strExecutable,
strResult;
DWORD dwHandle,
dwVerSize;
LPBYTE pBuffer;
UINT uBufLen;

FindExecutable(pszFile, pszPath, strExecutable.GetBuffer(_MAX_PATH));
strExecutable.ReleaseBuffer();

dwVerSize = GetFileVersionInfoSize(strExecutable, &dwHandle);
if (dwVerSize > 0)
{
pBuffer = new BYTE[dwVerSize];
if (NULL != pBuffer)
{
if (GetFileVersionInfo(strExecutable, dwHandle, dwVerSize, pBuffer) != FALSE)
{
if (VerQueryValue(pBuffer, "\\", (LPVOID *) &pFileInfo, &uBufLen) != FALSE)
{
strResult.Format("MajorVersion: %u\nMinorVersion: %u",
HIWORD(pFileInfo->dwProductVersionMS),
LOWORD(pFileInfo->dwProductVersionMS));
}
else
strResult.Format("VerQueryValue() failed. Error = %lu", GetLastError());
}
else
strResult.Format("GetFileVersionInfo() failed. Error = %lu", GetLastError());

    delete \[\] pBuffer;
}

}
else
strResult.Format("GetFileVersionInfoSize() failed. Error = %lu", GetLastError());

AfxMessageBox(strResult);
