Besides that, you could write a handler for the button and add member variables for the edit controls (CEdit type) and call SetWindowText to set the text.

It's better you to start with some books or articles to know more about MFC. it's difficult to whole process in a QA thread.
There are many methods, to get things done for your case in MFC.
You can add a control variable for All your edit boxes and can GetWindowText routine to get text of each items.
atoi(); routine will help you to convert string to integer data
itoa(); routine will help you to convert integer to string data
SetWindowText() routine will help you to set a control variable.
There are other routines called "GetDlgItemInt" etc.. to get the text in integer format.
I suggest you to better start with "Programming Windows using MFC" by Jeff Prosise. or with articles in MSDN or Codeproject

For learning, what's wrong with the Express compilers[^]?
E.g. Visual Studio Express 2008[^]
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Probably because MFC's are not included in the express editions. I now that was the case for VC2005 Express, I don't know if they changed it but I don't suppose so.

Oh - you are right. 
I used them for learning C# and liked them.

Perhaps this is a repost or perhaps you just have the same assignment as someone who posted a few weeks ago?
Either way you're not in for a fun time. Probably the best way for you to understand how large and complex a task this could be is for you to spend some time studying MSI ( Microsoft Installer ) which is part of Windows and has an API and database style tables and masses and masses and masses of rules and datasets and caveats and no doubt ultra-fat books written about it. If you still think this project is agood idea once you've got a grip on MSI then you'll know more about the subject than me and will be able to ask very specific and pertinent questions of the experts who lurk hereabouts. Good luck 
Nothing is exactly what it seems but everything with seems can be unpicked.

Why do you need to reinvent the wheel ? Can't you use something that already exists ? There are tons of windows installer on the market (some even free, like InnoSetup).

If you are have the handle for the Window, (CWnd or HWND), you can use SetWindowPos or CWnd::MoveWindow function to do the same.
Please rephrase your question. it's not really clear. It will be difficult to get an answer, if your question is not concise.

Same way as we create a dialog box from any other place.
MFC:
void CMyFirstDialog::OnAButtonPressed ()
{
CMySecondDialog dlg2 (this);
if (dlg2.DoModal () == IDOK)
{
}
}
Not quite sure how the windows start button comes into it, other than doing something when a button is pressed.

Same answer... Just written a bit differently.
Instead of "OnMyButton", you'll have a Dlg/Wndproc, with a
case WM_COMMAND:
...
case IDC_MYBUTTON:
DialogBox (hDlg, ... etc);
MFC is just nicely packaged SDK. Anyhinh it can do, you can do for yourself. The book keeping gets harder, but not the ideas.
Iain.

For make a dialog you can use of CreateWindow or CDialog class.

Hello
I need help on how to convert an array which its datatype is unsigned char to a string. The scenario is like this. I detect the mac address of a computer using GetAdaptersInfo API. So the return result of the call is the current MAC address which is available and the return Mac address is an unsigned char. So I can print the MAC address by using this code below :-
<br />
<br />
static void showMACArray(unsigned char MACData[])<br />
{<br />
<br />
printf("%02X-%02X-%02X-%02X-%02X-%02X\n", <br />
MACData[0], MACData[1], MACData[2], MACData[3], MACData[4], MACData[5]);<br />
}<br />
I want to print out as such that the Mac Data is in a string just like the code below :-
<br />
<br />
printf("The Mac address would be %s\n", MACData);<br />
<br />
I understand that i must concatenate each of the MACData[] array so that it combines together using strcat(). However, before using strcat(), i must convert each of the MACData unsigned char array to a string so that it can support the strcat() function. How can I solve this? Thank you and your help is really appreciated.

Alternatives:
- sprintf [^].
- CString::Format [^]
- Write you own converter: it is a simple programming exercise.

char buf[20];
snprintf(buf, 20, "%02X-%02X-%02X-%02X-%02X-%02X\n",
MACData[0], MACData[1], MACData[2], MACData[3], MACData[4], MACData[5]);
printf("MACAddr = %s\n", buf);
