How does one set the size of the text displayed in a CEdit (or RichEdit)? I can set up a RichEdit control so that new user input is displayed using the correct font, but data in the control populated by the app (SetDlgItemTextA(IDC_RICHEDIT21,_T("7.0"))) uses the default font.

For a CEdit, you'd need to create the font you want, and use SetFont. For text in a Richedit, as a guess, change the text selection to include all the text, and then use GetCharFormatSelection(), modify the font, and use SetCharFormat?
I haven't tried this, since I tend to allow the user to control what's in there instead. There should certainly be a message to allow you to set the format (including the font used).

Do you want to save this font for next run app?

I have a CFormView application that has alot of edit boxes
and so the right-hand scroll bars appear. They only way
to scroll down is to move the mouse over, click on the scroll
bars and scroll down.
How can I activate the mousewheel so that spinning that makes
the scrollbars move down?
Please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

Hi, I'm creating a variable, m_ulCounter, as
psuedo code below, non-compilable
Static declaration behaviour within MFC dialog
class blahDlg : public CDialog
{
//stuff
private:
static unsigned long m_ulCounter;
//stuff
};
Can I expect this static variable to act as its C counter parts - retaining it's value even though it might go in and out of scope?
Thanks.

Don't you hate it when people answer their own questions? 
Anyway, I found the answer:
C++: The Complete Reference::Herbert Schildt::Chapter 12:Classes and Objects:Page 311.
Loosely quoted: When you declare a static data member within a class you are not defining it and therefore not allocating any memory for that static data member.
You must define a global variable, outside of any class-scoped object, (define it in main (or what-have-you)).
Any class that uses this variable has the potential to change it - which probably led to the idea of fixing the wound in "shooting one's self in the foot" for C++ - which states (in one form or another): You accidentally create a dozen instances of yourself and shoot them all in the foot. Providing emergency medical care is impossible since you can't tell which are bitwise copies and which are just pointing at others and saying, "That's me over there."
Ref:http://m5p.com/~pravn/foot.html[^]

yes.
blahDlg::m_ulCounter will retain its value even if there are no blahDlg objects instantiated anywhere.

Guys,
Our main program calls a dll that it uses (obviously ). Know we want to use a newer version of this dll, but some of the functions have changed (name and/or arguments added and/or removed).
Is it possible to fool the calling program to call a wrapper that calls the dll? The idea is to rename the dll and add a new one (the wrapper) with the original dll name.
We want to do this to avoid fiddling with the source code of our main app.
(PS: hope I'm making sence  )
Many thanks !

Hi.
I'm writing an application that it create a CComboBox at runtime like this:
<br />
rcControl.left = long(rcClient.Width() * 0.05);<br />
rcControl.top = long(rcClient.Height() * 0.10);<br />
rcControl.right = rcControl.left + long(rcClient.Width() * 0.90) ;<br />
rcControl.bottom = rcControl.top +long(rcClient.Height() * 0.40); <br />
<br />
m_cboParam.Create(CBS_DROPDOWNLIST|LBS_STANDARD|CBS_SORT|WS_CHILD|WS_VISIBLE, rcControl, this, IDC_PARAM);<br />
....<br />
It works, but the problem is that I want to show more items when the user pull the list down. At the moment it shows just two items and I must scroll the list down to see the rest of them.
How could I set, maybe the heigth or something else, so it will be able to show more than two items.?? (at least 4 or 5).
Setting the amount of items to show in a combobox at design time is easy:->, just clicking over the arrow and then stretch it to the desire height. But how could I set that at runtime??
Thank you.

Forget it.;P
Solved.
I had just to adjust the height in other function when the controls reposition.
Thank you.

RECT given while creating combo box should mention that. ie.
in this case increase rcControl.bottom value, it will give you desired effect.

It is easy ,too. Isn't it?

Dear All,
I am developing a Windows Service application using VS.NET 2003. It was fine when I run it without adding any interface (ATL Interface).
Then I added one interface(ATL) called (ICallRDI) where I have written one member function (SendStatus).
Here I am getting this below error ?
: error LNK2001: unresolved external symbol _LIBID_RMILib
.\Debug/rdi.exe : fatal error LNK1120: 1 unresolved externals
this '_LIBID_RMILib' persented at CallRDI.h file.
I need to solve this. Kindly Help me in this.
Thanks.

Hi,
Could any one please guide me to know answer.
As I know TurboC is 16 Bit compiler and Windows is 32 bit OS. How it is possiable for a 16 bit compiler like TurboC is running in 32 bit OS(Windows)?
Thank you.

16 bits applications can be run on a 32 bits machine, just as 32 bits application can run on Windows 64 bits...

Hello Mr.Toxcct,
Very very happy to meet you in Codeproject. Thanks for your quick reply.
My actual doubt is how this TurboC compiler is( even it is 16 bit compiler )running in 32 bit OS(Windows). What is internully happening to run 16 bit things in 32 bit OS.
Here I have the answer same as you replied. But I dont have answer if any one says how it is possiable. I hope you got my question.
Thanks a lot.
Nice talking to you.

Just adding to Kakan's reply (I haven't gone through that link, may be this is given in that link). You might see windows running an executable named "Wowexec.exe" every time you run a 16 bit application on 32bit windows, which is actually that very subsystem.

Yaa!....
I got the answer.
Thanks for your reply.
=========================================================================
The WOW (Win16-on-Win32) layer consists of 32-bit window manager code and
Graphics Device Interface (GDI) code that translates 16-bit segmented addresses
into 32-bit flat addresses.
A 16-bit application cannot call a 32-bit application programming interface
(API). When an application calls a 16-bit API, the call goes to a stub routine ,
which in turn calls a 32-bit API. The 32-bit API performs the required action,
and the result is transformed into the format expected by the 16-bit API stub,
which returns the result to the application. This transformation is an example of
thunking.

unfortunately this is not working properly. Although a dialog box appears, the edit box that I want on it does not appear and some static text. If you have any information on what I am doing wrong, please tell me! Thanks for your time.
