Is it possible to reliably detect from the WIN32 level the current parallel port settings (and whether one is available) including mode (ECP, EPP, etc.)? If so, does anyone know the best way to go about this?
Thanks!

Look at Win32_ParallelPort in Platform SDK: Windows Management Instrumentation. You'll find a detailed information about the Parallel Port, and also, any other device installed.

I've just started writing custom control after reading excellent article on this site.
http://www.codeproject.com/miscctrl/customcontrol.asp
New class mostly looks like what in that article. But in OnPaint(), I want to get current font being set to that control and print text with it, so I do this;
void CLogViewCtrl::OnPaint()
{
CPaintDC dc(this);
RECT rect;
CFont *pOldFont;
CFont *pFont = GetFont();
GetClientRect(&rect);
pOldFont = dc.SelectObject(pFont);
dc.SetTextColor(RGB(0,0,0));
dc.SetBkMode(TRANSPARENT);
dc.TextOut(0,0,"Code Project is great!");
dc.SelectObject(pOldFont);
}
Then, I can do this like;
m_LogWindow.SubclassDlgItem(IDC_LOGWINDOW,this);
m_LogWindow.SetFont(&m_FixedFont,0);
I did that in OnInitDialog() of parent Window but, font was not changed. Trust me m_FixedFont is OK and same method is working for normal controls. I added
m_LogWindow.GetFont();
right after that .SetFont() line, but return font handle was NULL. Why??? I'm sure sending right font handle to that CWnd derived control by WM_SETFONT but it will return NULL with WM_GETFONT! I'm very confused.
Do I need to add special handling code for that? Simple CWnd window won't keep font handle? When I look at CEdit's source code, there is no code for Set/Get font handlings. Can anyone help me?
(Please don't tell me adding CFont data member to my class.)

Yes, you have to handle WM_GETFONT/WM_SETFONT yourself. Win32 controls are doing this for you. If you derive from plain CWnd, there's no such functionality in place.
In the Platform SDK docs, at "UI Services/Windows User Interface/Controls" you'll find the topics describing the default message processing done by controls. In the combobox section, for example, you'll find that combo "saves the specified font handle in an internal structure" during the WM_SETFONT processing.
When I look at CEdit's source code, there is no code for Set/Get font handlings.
This code lives outside the MFC - the Win32 edit control handles the message.

Now I understand what I should do.
I wonder how many people have this question trying to write custom control from scratch.
Thanks.

Question is not clear. What do you mean by value of a method? Is it about default arguments?

What type of app are you bulding? Is it dialog based or SDI/MDI, or don't you use MFC at all?

Have a look at Microsoft article Q218972. The IPicture interface works fine for me. You would also be able to support JPEG files if you used it.
Hope this helps.

I have an SDI app with static SplitterWnd with two panes. If I load a CFormView in both of them everything works fine. But if I load a CFrameWnd into one of the panes I get an Assertion Error (I think it's either CMainFrame::AssertValid() or CFrameWnd::AssertValid() ) when exiting the app. What am I doing wrong? Do I have to add any member functions to my CFrameWnd class? I've been trying to solve that problem for two days and I'm desperate. Please help me!
btw: In Release mode everything works alright.

Doesn't anyone have a hint for me?
Do you need more detailed information?
please someone help me!

Where do you get the assert? The call stack should show after the break.
Basically, I don't think you can put a CFrameWnd inside a splitter - I think CSplitterWnd expect its children to be CView derivatives. Don't ask me why! If you want to make a convoluted UI with views and splitters inside other views and splitters I suggest you use Zoran Todorovic's Visual Framework (http://www.codeguru.com/advancedui/VisualFx.shtml).
Cheers

Thanks a lot for your answer, Steen!
This really helps me a lot! You guessed right, I want to create a nested splitter. It should look like this:
------------------------------
|*CForm* |***************|
|*View** |***************|
|***1***|***************|
|---------|*****CView***** |
|*CForm* |***************|
|*View** |***************|
|***2***|***************|
-------------------------------
As i have been thinking about putting tabs in "CFormView 2" pane Zoran Todorovic's Visual Framework probably is the perfect solution for me. Thanks for the hint!
Anyway, if someone knows an easier (shorter) way of creating nested splitter please let me know!

How can I do this. Does someone know of a class already created...

You'll need to load a bitmap, draw text onto it and save it. The first and third can be done by a class that was added last week, and the middle is easy - CDC::TextOut

CXImage. I didn't look it up the first time because it's just in the section on bitmaps, where you'd expect it to be.

I'm an amateur programmer, and don't know that much about C++ and MFC. I was wonder just what exactly is MFC? What does it provide for or do for the programmer? What is it used for? Is it used for Win32 programming, or just in general? If it's used in Win32 programming, does it make the programmer's life easier? I would appreciate it if someone would try to answer all of my questions to the best of their knowledge. Thanks.

The Microsoft Foundation Classes are a set of classes that encapsulate and extend Win32, which has the net effect of making development more object oriented. For example, in Win32, you called functions to create a device context, stored the handle and then deleted it. MFC wraps those calls into a class called CDC. This is especially helpful if you have Visual Assist, because you create an object, add a dot operator and get a list of available methods, which sure beats looking through MSDN for a function you know exists but can't remember the syntax for. It is also safer because destructors can ensure an item is cleaned up, which is not the case in Win32 unless you write your own class. There are all sorts of additional classes such as CArray ( rubbish, you should use vector ) and CString ( much more useful than std::string ), right through to more complex classes that manage all sorts of things.
Your copy of VC should have come with a wall chart that maps the relationships between all the MFC classes. You'll find the majority of the code on this site uses MFC. VC wizards build all the boiler plate MFC code for you, so for example to create a window or dialog takes more work in Win32, not least because the compiler isn't writing the basic stuff for you.
That's a simplistic explanation but I hope it gives an overview.
