Thanks for your replay , I didnt understand where is the calling to the method of object 2,
if you can mark this section it will be helpfull for me.
by the way I forgot to specify that I am using MFC but as I realized it doesnt matter.
thanks

That's okay. In fact - I didn't make any call to the method of object 2. Please accept my apology for being unclear.
As I alluded to earlier, I can see two places where such a call would make sense.
In the first case, there would be action immediately after a radio button was pressed.
I imagine you would not have the same need to keep track of the currently selected option, so I've omitted that code from the following case statements.
Example 1: Immediate response
case IDC_RADIO1:
object2.handleSelectedRadioButton(1);
return true;
case IDC_RADIO2:
object2.handleSelectedRadioButton(2);
return true;
case IDC_RADIO3:
object2.handleSelectedRadioButton(3);
return true;
In this second example, you'll need to remember which radio-button is selected somewhere, before taking the appropriate action when the trigger is received (in this case, the pressing of the button labelled Test)
Example 2: Action taken in response to another input
case IDC_BTN_TEST:
if (curRadioOption == -1)
MessageBox(hwndDlg, "Select a radio button first!", "Error", MB_ICONERROR);
else
object2.handleSelectedRadioButton(curRadioOption);
return TRUE;
Something else I should mention, is that MFC will most likely allow the state of any control to be quickly and easily queried (not sure if there's an object used to represent a group of radio buttons - I'd imagine that there was) This will make my global variable curRadioOption redundant.

Pass a pointer to the object you want to notify in the constructor of the dialog, and have the dialog save that in a member variable.
Then when events occur, make a call to that object.

The dialog is closed by clicking the Cancel button, the X, Esc, Alt+F4, or by calling EndDialog(). Where are you wanting to save its data to? Some internal data structure, or some external storage like a file?

dialog.I am calling dialog boxes from the Viewclass.but didnot find how to close or switch to other dialog when user click the other options of open other dialogs
Do yo have any coding to calling mulitple dialogboxes in SDI applicaiton
Thanks

You need to first understand the difference between modal and modeless dialogs.

Hello,
is there any c++ tutorial or (simple) open source sample how to write an OLE object that can be embedded into MS Office applications such as powerpoint?
Just like, for example, an Origin Graph or a corel draw image which are directly embedded into a powerpoint presentation.
When I search for OLE, I most often only find how to automate Office...

I can insert my ActiveX object into Powerpoint and save/restore the data.
Now, I would like to automatically create a new object from a certain file type - ideally by drag and drop into Powerpoint. How can I achieve this?
Thank you in advance.

I never did that, however, I suppose you have to write a Shell Extension for that, check out the great article series[^] of Michael Dunn, here at CodeProject.

Please don't post the same question at multiple places.

Alright, Fine, I got that. Now any answers?

Hi All,
I have a function in C++ dll like
FunctionCPP(int s)
{
}
I have a function in C# application(exe) like
int FunctionCSharp(int s)
{
return s;
}
what is the procedure to call FunctionCSharp from FunctionCPP?
Any help will be appriciated.
Thanks

Not sure how this would work with a C++ DLL loaded into a C# application, but read what MSDN[^] says here, maybe it can get you going.
Registering/Using somekind of inbetween COM interface sounds like a good idea.

hi all
here is the my code[quick_sort),plz point the errors,remove the errors plz
i want run this programme in fedora also[what exactly the header file would be to find time consumed for sorting a given array[sorted/unsorted] ]
#inlcude<stdio.h>
#include<conio.h>
#include<time.h>
Const int MAX=1000;
Int partition(int a[],low,int high)
{
Int I,j,,temp,key;
Key=a[low];
I=low;
J=high+1;
While(i<=j&& key<=a[i]);
{
i++;
}
While(key>a[j]);
{
j--;
}
If(i<j)
{
temp=a[i],a[i]=a[j],a[j]=temp;
}
Else
{
Temp=a[low],a[low]=a[j],a[j]=a[low;
Return j;
}
}
Void quick_sort(int a[],int low,int high)
{
Int mid;
If(low<high)
{
mid=partition(a,low,high);
quick_sort(a,low,mid-1);
quick_sort(a,mid+1,high);
}
}
Void main()
{
Int a[MAX],n,I;
Clock_t end,start;
Start=clock();
Printf("enter the no of elements:");
Scanf("%d",&n);
Printf("\n enter the elements to sort\n");
for(i=0;i<=n:i++);
scanf("%d",&a[i]);
quick_sort(a,0,n-1);
end=clock();
printf("\n the sorted elemetns are:\n\n"(;
for(i=0;i<=n:i++);
printf("%d\t",a[i]);
printf("\n\n time consumed the array is: %5.2f sec",(end-start)/CLK_TCK);
getch();
}

One thing I noticed is that u are starting the clock before providing the input so if u take 5 minutes to enter the elements it will also be counted as time-took-to-sort. so better move the start & end as below:
<br />
<br />
Start=clock(); <- remove from here<br />
Printf("enter the no of elements:");<br />
Scanf("%d",&n);<br />
Printf("\n enter the elements to sort\n");<br />
for(i=0;i<=n:i++);<br />
scanf("%d",&a[i]);<br />
Start=clock(); -> put it here<br />
quick_sort(a,0,n-1);<br />
end=clock();
now the algorithm running time is not including the time for printing the messages and taking user input.

One more thing, i have not done the statistical analysis though but u are using 2 while loops one nested inside other why not simlify it with one while loop, Here is my implementation for the same, hopefully it will help:
<br />
void swap(int a[], int i, int j)<br />
{<br />
int temp = a[i];<br />
a[i] = a[j];<br />
a[j] = temp;<br />
}<br />
<br />
void qsort(int *arr, int first, int last)<br />
{ <br />
int pivot;<br />
int left = first;<br />
int right = last;<br />
<br />
assert(arr != 0);<br />
if(left >= right)<br />
{<br />
return;<br />
}<br />
pivot = left++;<br />
while(left <= right)<br />
{<br />
if(arr[left] < arr[pivot])<br />
{<br />
swap(arr, left, pivot);<br />
pivot = left;<br />
++left;<br />
}<br />
if(arr[right] > arr[pivot])<br />
{<br />
swap(arr, right, pivot);<br />
pivot = right;<br />
--right;<br />
}<br />
}<br />
<br />
qsort(arr, first, pivot - 1);<br />
qsort(arr, pivot + 1, last);<br />
}<br />

hi Rahul
thanks for the reply
but your programme[modified used 1 while] doesnt give the time consumed to sort the given array
right?
|
|
|
|
|
Well I will then suggest the use of Boost's time duration class. I think there is one because i used to sometime back. check out the documentation of boost.
