How, can it be done? You said not automatically, so it is possible.

Well, the first thing to clear up is to remove the thinking that C++ and MFC are mutually exclusive things. One is merely a subset of the other. Converting a VB project to a C++ projects makes more sense than converting a C++ project to an MFC project. MFC is a tool that is used within, not in place of, a C++ project.
That said, what sort of C++ project are you wanting to convert? If it is GUI based, it is probably a good candidate to use MFC. If not, then an STL project might be more fitting.

David, Its an STL project that I am running from the command line. How do i go about converting that into MFC?

Use AppWizard to create an MFC project. Decide if it will be SDI, MDI, or Dialog based, and then add the necessary files from the STL project.

Hello,
I'm looking for a way to let the PC Speaker beep, but it must be asynchronous. The function I could find - Beep - is syncronus. :/
Thanks for the help,
Michael

Asynchronous standard beep using computer speaker:
MessageBeep((UINT)-1);
Best regards, 
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)

Thanks Dominik, though the MessageBeep isen't what I'm looking for, because it does play the default windows .wav sound and I actually need the PC-Speaker playing the sound.

Read MSDN!!
MessageBeep
The MessageBeep function plays a waveform sound. The waveform sound for each sound type is identified by an entry in the [sounds] section of the registry.
<br />
BOOL MessageBeep(<br />
UINT uType
);<br />
Parameters
uType
Specifies the sound type, as identified by an entry in the [sounds] section of the registry. This parameter can be one of the following values: Value Sound
0xFFFFFFFF Standard beep using the computer speaker
MB_ICONASTERISK SystemAsterisk
MB_ICONEXCLAMATION SystemExclamation
MB_ICONHAND SystemHand
MB_ICONQUESTION SystemQuestion
MB_OK SystemDefault
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
After queuing the sound, the MessageBeep function returns control to the calling function and plays the sound asynchronously.
If it cannot play the specified alert sound, MessageBeep attempts to play the system default sound. If it cannot play the system default sound, the function produces a standard beep sound through the computer speaker.
The user can disable the warning beep by using the Sound Control Panel application.
Windows CE: Passing 0xFFFFFFFF will cause the SystemDefault waveform to be played.
QuickInfo
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Requires version 1.0 or later.
Header: Declared in winuser.h.
Import Library: Use user32.lib.
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Yes, I read the MSDN and I also wrote a test program, but even when I pass 0xFFFFFFFF or ( (UNIT)-1 ) it just plays the system default sound using the sound card and not the PC Speaker.
Nevertheless, thanks for the help,
Michael

How about sndPlaySound(..., SND_ASYNC)?

Thanks David, though I took a look at the functions and it's just playing .wav files and I need the PC-Speaker ( that old horrible thing ) playing the sound.
I guess I will start a extra thread just for the beeping

Basically you'd use it to store persistent state information... user preferences, window size/position, etc. However these can also be stored in a private file (INI or any other type of file) as you see fit and ignore the registry completely.
Just one tip, there are a few different root-level registry hives. Application data should probably go in the HKEY_CURRENT_USER hive - this is meant for user-specific data (for instance, user A can have preferences one way, and user B can have preferences another way.)
Sometimes I feel like I'm a USB printer in a parallel universe.

Would you recommend using the windows registry rather than an INI file or would you use them both? Is there any other hive that I would use other than HKEY_CURRENT_USER? Also is there any documentation on that I can read about store data in the windows regestry? Whether it is on codeproject or another site??
Thanks Navin!

I sometimes put registry settings under HKEY_LOCAL_MACHINE for necessary things for the app, and under HKEY_CURRENT_USER for personal settings.
If it's broken, I probably did it

A user requires special privilege to write to the HKEY_LOCAL_MACHINE
If you store user-secific settings in a file, make sure to put them in a 'company specific' subfolder of the user's douments and settings folder, so if they 'roam' it should be available on the network.
If you use the MSDN and read about terminal services, you can be made very aware of ths issues of supporting multiple users from the same computer. Also, there are the windows logo guidelines that detail where your program should write certain classes of files to certain subdirectories on the computer.

Ahoy..
I guess you all probably know the folder dialog in Visual Studio whenever you're creating a new project. You can choose to browse for the desired folder to put your project in, like this:
http://www.blacksmith-studios.dk/ChooseFolder.JPG[^]
Anyways, I'm wondering how one can do this in MFC? It seems the CFileDialog class doesn't support the selecting of folders :S
Thanks a bunch

Will SHBrowseForFolder() suffice?

Well, that's what I used the last time.
Was just curious if I could do it the way Visual Studio does.

I am familiar with using PropertySheets in a Dialog application . Basically , I create the PropertySheet in my main dialog and add PropertyPages to it . Now I was looking at CTabCtrl as a common control that I can drag and place on my main Dialog . How do I manage whats shown ?
As for eg :
Say If I had a PropertyPage with the following :
Page 1 : 1 radio Button(A) , 1 editBoxe(B)
Page 2 : 1 Combo Box (C)
Now If i dont use a PropertyPage , but want to use a CTabCtrl ?
Do I need to create A , B and C all at once and keep hiding the appropriate based on the Tab selection ?
How does it work ?
Engineering is the effort !

Yes, since TabControl does nothing except of drawing pages tabs, you will have to do everything yourself. You don't have to create all controls at once, only those which are curently shown. I prefer creating/hiding full dialogs - you create dialogs in resource editor, make it no-border, control-style, and than switch it by TabControl notification.

I use the shell's supplied IExtractImage interface to extract thumbnail-images of files...
When the shell tries to get the thumbnail image for a .url file, it sometimes fails, which is cool, but it also decides to popup an annoying message box saying 'The Page !@#!@# could not be loaded and rendered within the timeout period' or something slightly different on other OSs.
Explorer obviously doesn't show these messageboxes, but how ? There doesn't seem to be a way to influence this through the interface, has anybody hit this problem ?
thanks

Hello everyone,
I am in the middle of designing my first MFC application and I was wondering what I would use the windows registry for. Why would I use the windows registry? I see alot of applications enter infromation into the windows registry but I never understood why they would put it there or what they would put it there for. Can anyone help explain this to me??
Thanks in advance!

if you have some settings or data, that you want to store between two starts of your app, you can save it to the registry.
if you have a ListControl, you can save the size and the sort-order of the Control in the registry, so the App is more customizable for the user.
