I'm not exactly sure what you are trying to say. If you are trying to say that technically MFC is C++ then yes you are correct but the MFC library is I think about 1.5 megs that I really have no use for until this little problem. So by straight C++ I meant C++ without additional huge libraries (I know that my includes add some extra baggage but it is still far less than MFC and I'm trying to minimize them as well). I guess that does sound a little too much like the common term "straight C" that is used to differentiate C from C++ but that is not what I meant.
I would have to argue with you about weather MFC would have made it much easier to do what I am doing however. All my program does is read a file and output it to the screen with some additional formating that requires me to output a single character at a time. This make the CString class almost useless for this. Additionally, I have no controls and only 2 very simple dialogs in the app (plus a Common Dialog). I guess it's what you're used to but, aside from the CString class and couple other handy features, MFC seems to be more of a hastle than it is worth. I can't tell you how much time I have spent trying to get MFC to not do something or other. True, it is the way to go for medium to very large apps, but for the smaller stuff (like my little text viewer) I prefer not to use it.

It's a common misconception that C++ knows about things such as input/output, files, Windows, etc. I was simply clarifying that without extra packages such as STL, WTL, ATL, or MFC, what you are after is not possible.

Unless the code will be running on a cell phone or an older PDA, trying to optimize for size is not a worthy exercise. Thinking about "how big" the code is almost always leads to a lot of effort that produces no payback whatsoever. What matters is how big the data is. This goes back to the days when programmers were taught that "smaller is better."

With what you've described so far, I'm seeing a dozen lines of code, maybe two.

I've never known CString to be useless for much of anything. Do you have an example?

How can you have a dialog without any controls?

How to obtain a CWnd* pointer for every control on a window?
|
|
|
|

First you have to enumerate all top-level windows with the EnumWindows() function.
Then you can use the EnumChildWindows() function to iterate through the top-level windows to get the window controls.
Hope it will help you...

Both functions iterate through the top-level windows??

Use EnumWindows() to get all top-level windows. Then use EnumChildWindows() to iterate through all childs of every top-level window...

Or you loop through FindWindow and FindWindowEx which provide same functioality like EnumWindows and EnumChildWindows

Inside of the Update() method, declare three local variables that hold the contents of the member variables. Then in the __asm block, reference the local variables.

I think you are referring to a system-model dialog box.

The name is misleading. It is the SDK you want for Windows 2000.

What part of "The name is misleading. It is the SDK you want for Windows 2000." was unclear.
Download it. Install it. Enjoy!

How to use Different font sizes in a VC++ Dialog Box
|
|
|
|
|
Right click on dialog select properties; from the general tab select the font size you want.
|
|
|
|
|
If you want to do it at run time, override the virtual function DoModal();
#include <afxpriv.h>
int CMyDlg::DoModal()
{
CDialogTemplate dlt;
if (!dlt.Load(MAKEINTRESOURCE(CMyDlg::IDD)))
{
return -1;
}
WORD nFontSize = 10;
TCHAR chFaceName[100] = "Courier New";
if (GetNewFontSize(....))
{
nFontSize = newsize;
}
if (GetNewFaceName(....))
{
lstrcpy(chFaceName, newfacename);
}
dlt.SetFont(chFaceName, (WORD)nFontSize);
LPSTR pData = (LPSTR)GlobalLock(dlt.m_hTemplate);
if (pData == NULL)
{
return -1;
}
m_lpszTemplateName = NULL;
InitModalIndirect(pData);
INT nResult = CDialog::DoModal();
GlobalUnlock(dlt.m_hTemplate);
return nResult;
}

I use a method similar to this with a highres app and it works great. On a highres monitor (2048 x 2560) I use 15pt font and on the second (1024x768) I use 10pt...

Hi all,
I'm new to C++ and am trying to write a kind of predictive text program where the text from a file will attempt to be predicted by the program. Atm I'm trying to get started by reading the text from the file a character at a time and having each character be displayed to the screen after a press of a key. I've managed to read the text and display it as a complete word but am having trouble reading and displaying it a character at a time. I've messed around with cin.get, cin.getc, cin.getchar etc and can't seem to get them to work correctly 
Any help on how to go about doing this would be greatly appreciated, Thanks.
The short program below is how I read the text from the file and displayed it to the screen:
Note, to avoid the console window disappearing, you have to run it using CTRL+F5. If there is another way to stop it closing please let me know. I'm using MS Visual C++.NET btw.
=====================
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
char buffer[256]; // Create 256 bit character array.
ifstream file_op; // Create an output stream variable.
file_op.open("mytext.txt"); // Open the text file to read from.
while(file_op >> buffer)
cout << buffer << endl; // Display complete text (complete word)
file_op.close();
return 0;
}
