In the OnBeginPrinting function of my view class I am displaying a CFontDialog dialog box. I want the default font to be Arial and the default size to be 8. When the dialog box displays, it a shows default size of 50.
Here is the code. These are the first lines in the OnBeginPrinting function.
ASSERT(pDC->GetMapMode() == MM_TEXT);
LOGFONT lf;
::ZeroMemory(&lf, sizeof(LOGFONT));
lf.lfHeight = -MulDiv(10, pDC->GetDeviceCaps(LOGPIXELSY), 72);
lstrcpy(lf.lfFaceName, _T("Arial"));
CFontDialog dlg(&lf, CF_PRINTERFONTS, pDC);
if (dlg.DoModal() == IDOK)
{
m_strFont = dlg.GetFaceName();
m_nPointSize = dlg.GetSize() / 10;
}
The value returned by pDC->GetDeviceCaps(LOGPIXELSY) is 600.
The computed value for lf.lfHeight when 8 points is used is -67.
The resulting size value in the Select Font dialog is 50.
Why is the Select Font dialog displaying as font size of 50 instead of 8?
Here are the results from some other point sizes.
input dialog box
8 50
10 62
12 75
14 88
20 125
Every example of code I can find looks just like the above. Why is this code not working?
Thanks!

Why do you think it is not working?

I have found the answer.
lfHeight must be converted from print units to screen units because the CFontDialog class uses screen units. Here is the updated code:
ASSERT(pDC->GetMapMode() == MM_TEXT);
LOGFONT lf;
::ZeroMemory(&lf, sizeof(LOGFONT));
int nPrintDpi = pDC->GetDeviceCaps(LOGPIXELSY);
lf.lfHeight = -MulDiv(10, pDC->GetDeviceCaps(LOGPIXELSY), 72);
HDC hDC = GetDC(m_pView->m_hWnd);
int nScreenDpi = GetDeviceCaps(hDC, LOGPIXELSY);
lf.lfHeight = MulDiv(lf.lfHeight, nScreenDpi, nPrintDpi);
lstrcpy(lf.lfFaceName, _T("Arial"));
CFontDialog dlg(&lf, CF_PRINTERFONTS, pDC);
if (dlg.DoModal() == IDOK)
{
m_strFont = dlg.GetFaceName();
m_nPointSize = dlg.GetSize() / 10;
}

I have my own Win32 API GUI based on an image etc, and i want to insert
an IDD_FORMVIEW inside a certain area, is this possible?
because if it is it means i can make it frameless and add a menu etc, makes life a bit easier
also if it is, where would i look to find out how its done, i tried google but for this im not sure what im searching for.

What is a "IDD_FORMVIEW"?
I'll assume you mean a dialog window.
Dialogs are windows (represented by an HWND). You can make a dialog window
a child window just like any other window (except popup style windows).
You can use MoveWindow() to position/size a child window in its parent's client area.
Since you're new to this, you may also want to study Windows Windowing[^]
to understand the fundamentals and the proper terminology.

cheers mark  im doing random bits and bobs here and there lol
learnt a lot though in a short space of time, ill take a look
btw the IDD_FORMVIEW is a resource visual studio thing when you add a new dialog there is a plus arrow and one of the options is that

I have coded application to retrieve any running process's arguments and worked very well in Win32, but falied in 64 bit Windows(x64).
The approache is to use NtQueryInformationProcess to get PROCESS_BASIC_INFORMATION which has the data structure like:
typedef struct _PROCESS_BASIC_INFORMATION {
PVOID Reserved1;
PPEB PebBaseAddress;
PVOID Reserved2[2];
ULONG_PTR UniqueProcessId;
PVOID Reserved3;
} PROCESS_BASIC_INFORMATION;
and then use ReadProcessMemory() to get dwInfoBlockAddress in PEB2, like
struct _PEB2
{
DWORD dwFiller[4];
DWORD dwInfoBlockAddress;
} PEB2;
and so on
Here is the partial sample code:
NtQueryInformationProcess)(hProcess, ProcessBasicInformation,
&pbi, sizeof(pbi), &dwSize);
ReadProcessMemory(hProcess, (LPCVOID)pbi.PebBaseAddress,
&PEB2, sizeof(PEB2), &dwSize);
ReadProcessMemory(hProcess, (LPCVOID) PEB2.dwInfoBlockAddress,
&Block, sizeof(Block), &dwSize);
cmdLine = (TCHAR *) malloc (Block.wMaxLength+10);
ReadProcessMemory(hProcess, (LPCVOID) Block.dwCmdLineAddress,
cmdLine, Block.wMaxLength+10, &dwSize);
It failed in getting dwInfoBlockAddress of PEB2. Can any of you provide some hints/helps. Maybe the memory structures/address are totally different between 32 and 64 bit data models....??? The problem is there is no useful documents I could look at.
Thanks a lot.

I am new to device drivers.Can anybody tell me from where it is possible to download
Windows Driver Kit
Windows Logo kit
Windows Driver Framework
I have tried this to download from microsoft websites.But it seems that the link is not there.
https://connect.microsoft.com/directory/

I tried these.But was unable to find.

AFAIK there is no longer a separate DDK for Windows driver development. Look for Windows Development Kit 6.1 . That's supposed to have everything you need in it.

Windows SDK for Windows Server 2008 and .NET Framework 3.5
Is this i should download.It is about 1.2GB

AFAIK Microsoft have combined the DDK into the SDK and this is the latest SDK. Yes it's HUGE, that's why it starts off by downloading a special tool for downloading the rest of it. If you're serious about wanting to develop software then the ~$10 worth of bandwidth is probably worth it. The last time I downloaded an SDK over 56K it was 400+MB and took a week to download. Such is life.

I ask Robert.
Every time there is a question in the C++ board, I ask Robert. Robert answers all the questions. He has to. I beat him with a calfskin leather belt until he does.
