This makes no sense. You can do the following from within any class:
CDatabase db1;
CDatabase *db2 = new Database(); himangshuS wrote: Also please suggest if the idea of creating the global class is alright.(All I needed is to call a function from different dialog classes).
I see nothing wrong with that approach.

Give more details, please, how do you mean "destroy it", how/when you try to do it and what happens?

thanks for your reply
I got my problem
|
|

First i wrote this code to test some algorithm. And it's work but somehow there is a problem when i assemble it with another program. This is some code of my program.
<br />
#define numpic 2 // or const int numpic = 2;<br />
#define numline 20 // or const int numline =20;<br />
int numpictest;<br />
<br />
void swapy(int a[numline][numpic])<br />
{<br />
...<br />
}<br />
<br />
void main()<br />
{<br />
readnumpic(numpictest);
numpic = numpictest;
int size[numpic]; <br />
...<br />
}<br />
As you can see that my function and declaration use the value from defined value. But i want this program to be more dynamic (I can change the "numpic" and "numline" variable in main). So is there a way i can change defined value or const value?
Thank you for every help.

You cant change value of constants.

Why would you do that ? If it is constant, it means it can't be modified. Why do you declare it as constant then ?
And for the #define, it is just a preprocessor directive: before compiling your sources, every occurence of the text "numpic" will be replaced by the text "2". So, it's normal that you can't assign anything to it.

As Cedric said, think about what the compiler sees.
#define numpic 2
...
numpic = numpictest;
becomes:
2 = numpictest;
You would not expect that to work.
As for the other option...
Look up the work "constant" in the dictionary.
If you want it to be casually changable, that is the exact opposite of a constant. A Variable.
I'm not sure how to give a more helpful / friendly answer, as it will depend a lot on the rest of your application, and how you're interacting from different programs. Do you want to pass a number as a parameter?
ie:
myalgorithmapp.exe /pi=7.2
?

thank you .

That code was easy first you need to set your device (waveaudio) and then you need to open it for use then you need to set MilliSeconds that you want to record and then you send MCI_RECORD to your device and finaly you need to save ypur file with set its name(MCI_SAVE).

From where does it take the input. Do you read it from some device?
Markandaiya Harsh wrote: user which note(for the octate) was played,
How does the user play a sound?

You need to google first, if you have "It's urgent please" mentioned in your question.
