Hi,
Is there a way for me to automatically call an original member function from an overloaded function?
Like let's say I have a class, Class, which is inherited from BaseClass. BaseClass has member function "OnSave" and Class has its own version of "OnSave." Is there a way I can automatically have Class's OnSave call BaseClass's OnSave whenever it is called?
I don't want to do something like:
BaseClass::OnSave();
I want it to automatically call its inherited OnSave without me having to put that line of code in.
Thanks!

You need to specifically/explicitly call the base class implementation.

Calling base class version of function is your or rather implementation "need".
There is not such implicit mechanism available for that and can not be provided due to resaon stated in my first argument.

IFAIK this is the only way to call the base class member.

I want to animate an object(lets say a square that continualy rotates around)
and then able to select it and drag it to a differnt posistion with a mouse/keyboard
I have a very basic understanding of mfc, my guess to go about this
is to use a loop in the ondraw section with the settimer function
but I get a bit confused on how the mouse/keyboard listner will be implemented
would anybody be kind enough on giving me a quick explaination or soloution to the above mentioned.
thank you
Simon

Simon, why did you cross post this into the Vista forum?
Don't you think books and articles on the internet are available that discuss and provide examples of animation? Probably even some on this site.

Probably he wants his animation Vista compatible?

For animate an object MSDN has an article that I think its helpful for you I think its name was Cube.

And to Drag-Drop a way to do it is:
1) When MouseDown save the point of the click and set a bool variable i.e. bAllowMoving to TRUE
2) OnMouseMove, ask bAllowMoving, if TRUE, update the saved point with the actual coordinates
3) When MouseUp, if the bAllowMoving is TRUE, get the last point of the click-release, move your object to that point, erase background and update window/view. And reset the bAllowMoving.
Greetings.

What in the world does this mean?

You've coded all of this, yet you cannot figure out how to ask a question and call a different function depending on the answer.
printf("Convert to (b)in or (d)ecimal? ");
char c;
scanf("%c", &c);
if ('b' == c)
bintodec();
else if ('d' == c)
dectobin();

how to make this code into a function?

i have tried to come up with my own way of having a code but its not working ...corect it please .
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
/* Function Prototypes */
int bintodec(int fmbase, int num);
int dectobin(int tobase, int num);
int main()
{
int num;
int fmbase;
int tobase;
int result;
int convert;
int counter = 0;
int bin [25];
int quo = 1;
printf("Enter 0 to convert to binary\n");
printf("Enter 1 to convert to decimal\n");
scanf("%d",&convert);
printf("Enter the value to be converted:");
scanf("%d",&num);
printf("Enter base to be converted from: ");
scanf("%d",&fmbase);
printf("Enter base to be converted to: ");
scanf("%d",&tobase);
if(convert ==0)
convert= dectobin();
else if (convert ==1)
convert= bintodec();
else
{
printf("Error in Input");
exit(1);
}
result = bintodec(fmbase,num);
printf("The result is:%d", result);
result = dectobin(tobase,num);
printf("The result is:%d", result);
int dectobin( int tobase, int num)
do (quo!= 0)
{
quo= num/tobase;
bin[counter] = num%tobase;
counter ++;
num=quo;
}
while (counter > 0)
{
printf( "%d", bin[counter-1]);
counter --;
}
int bintodec(int fmbase, int num)
{
int bin[256];
int counter ;
int counterR ;
int quo ;
int result =0;
int result1 =0;
int res[256];
int sum =0;
if(quo>0)
{
quo= num/10;
bin[counter] = num%10;
num=quo;
counter++;
}
while (counter>0)
{
result = pow(fmbase, (counter-1));
result1=result*bin[counter-1];
res[counterR]=result1;
counter--;
counterR++;
}
while (counterR > 0)
{
sum = sum + res[counterR-1];
counterR--;
}
return sum;
}
system("PAUSE");
return 0;

Other than the function it already is in? Apply some logic here, Nick.

Good luck.

Helping you and doing it for you are two different things.
Why can you put together two functions, but not a third?  That makes no sense, unless you've been sleeping in class.

In dialog box if we have tab control we can have many pages. How to exchange message from one page to another?
|
|
|
|

The values should belong to the dialog and passed to each page. in each page you update the values in the dialog.

Thank you for your reply.
Could you explain more clear?
Supposed in page1 user input a number x=5, how to transfer it to page2?
