Hi,
I have a class, i don't want any other class to be derived form that.
How can i do this?
Regards
Neha

Make the constructor private.
|
|
|
|
|
Eventhough i make the contructor i can derive(Public) other class from that.
What i want is during Compile time itself it should give some error.

I gotta say 1st that I'm a nooB. 
When ever I make a simple program, when its finished what its meant to do, it will close straight away, often being too fast to see the last output. As I said, i'm a nooB so I dunno how to stop it. 
Can you help?
(e-mail)

It sounds like the program you have created is for the command prompt, and you are running it within the VisualStudio environment - a command prompt will be opened, your program will run, and the prompt will automatically close and thus you dont see much. Open a command prompt yourself, change to your programs directory, and run it from there rather than from VisualStudio

Hi,
I am working on a problem has to do with manipulating large files. Essentially, the program will open up any give files and append, insert, and delete data from the file at random position.
What is the most efficient solution?
I have tried memory mapping, but it does not work as expect. Memory mapping works only when the program change a byte in the file. It does not work for inserting and delete bytes from the file at random position.
Thanks,
Kuphryn

Unfortunately there are no direct API's for inserting into and deleting parts from a file, file mapping is not be advisable because of large files.
Help yourself with constructing new files from the needed parts of your original files/data.
If your files are large compared to the available memory then you should use in a loop small chunks of data (~1MB) at a time in order to avoid unnecessery memory overhead.
Use SetFilePointer to mark the position of current reading/writing operation.
In order to not block the UI, put the whole operation into a worker thread.

I'm pretty much a complete newbie to the programming scene. I can't for the life of me work out how to play a wave file. Preferably during the startup of the application but even if it was on the press of a button. I have read about the PlaySound and DirectSound classes/functions (whatever they are) but cannot get them to work. Also i have come across what looks like a really good class (cSound) for download on this website but apparently it doesnt work in Windows XP, and i cant get that to work either. I need to know everything i would need to do (initialisation and all that) coz im completely lost and this is getting very frustrating. even a link to a class i can use or step by step tutorial would be a big help.
o and im using VC++.net
Cheers

Whether you beleive or not it is really as easy to play a wave file from your app as writing the following:
sndPlaySound("c:\\yourwavetoplay.wav",SND_ASYNC);
Put it into your OnInitDialog override to play it on application startup.
However, in order to use it, you have to add the windows multimedia library to your project
So, BEFORE you call the above line, add to your code:
#include "mmsystem.h"
#pragma comment(lib,"Winmm.lib")

does anyone know the code for a calculator like the one microsoft uses in the accessories file I am interested in how they get the plus and equal buttons to add the values using only one edit box.
thanks JKohm

They use a spare variable in addition to the display, and also an operation variable (i.e. three variables). By clicking on an operation button (+,-,*,/) the contents of the display are put into the spare variable, and the the button is stored in the operation variable.
The equal sign calculates: spare variable OPERAND display, where OPERAND is the operation variable.

I haved binded the MSHFlexGrid with a recordset, and now I want the result that if I scroll the mouse wheel, the record showed in the MSHFlexGrid would scroll(like the effect as we scroll the mouse wheel while we read a web page,the scrollbar move up or down);I have coded below:
BOOL Class::OnMouseWheel(UINT nFlags, short zDelta, CPoint pt)
{
// TODO: Make the mouse wheel take the MSHFlexGrid scroll
this->m_cHFlexGridPerform.SetScrollTrack(true);
//Would u tell me how can I make it work please
return CFormView::OnMouseWheel(nFlags, zDelta, pt);
}
thank you in advance;
