Hi all,
i Have a problem regarding multithreading....
Actually i am having a list control in that list control i having 2 columns one contaning url value n other for displaying result....
this i have done through making a class for ping which is derieved from CWinThread class...
if i run a single class then the result displayed in the list control column is correct but instead if i select more than 1 value then the result displayed is same (both rows contain same value). But the value calculated for ping is correct..problem is in displaying it in listctrl..
for sending messeage i have used SendMessage function .
Can anybody help me in this...
thanks in advance

Your secondary thread should not be sending messages directly to the list control (which belongs to the primary thread). Post a message to the primary thread instead, and let it update its controls. See here for more.

Hi
I have a homework about finding amicable numbers
[[[[
Amicable numbers:Two numbers are called Amicable(or friendly)if each equals to the sum of the aliquot divisors
of the other.Aliquot divisors mean all the divisors excluding the number itself. For example,
aliquot divisors of number 220 are 1,2,4,5,10,11,20,22,44,55 and 110. The aliquot divisors of number 284 are 1,2,4,71 and 142.
If we represent anamicable pair by(m,n)and sum of aliquot divisors of m and n by(m)and(n)respectively,then for amicable pair(220,284)we get
(m)=(220)=1+2+4+5+10+11+20+22+44+55+110=284=n
(n)=(284)=1+2+4+71+142=220=m
]]]]
my teacher wanted this programs code in C++ without using any arrays(we are allowed to do this with if,while,for,do while).And also the program must be like this:
220 and 284 are amicable numbers.
Number of amicable number less than 1000 is 1.
1184 and 1210 are amicable numbers.
2620 and 2924 are amicable numbers.
5020 and 5564 are amicable numbers.
6232 and 6368 are amicable numbers.
Number of amicable number less than 10000 is 5.
....
....
....
....
It must survive up to 10^10.
Please help me,I will so appreciate...

I'll point you in the right direction to help you do it yourself.
First off you clearly need a function to compute the aliquot divisor of a number.
Second you need to decide how to find the pairs. (assume that you need to detect/avoid duplicates) I think a simple loop can handle this problem.
You need to go through the thought process. You can get help for that here - maybe.

I cannot do it by myself.I found these codes in this site but it has an array like int get_sumf(int val).We are not allowed to do that.How can I do it without ant array???
#include <stdio.h>
#define MAX 10000000000
int get_sumf(int val)
{
int sum = 1;
int k;
for (k = 2; k <= val / 2; ++k)
if (val % k == 0)
sum += k;
return sum;
}
int main()
{
int i, k;
for (i = 2; i < MAX; ++i) {
int val = get_sumf(i);
for (k = 0; k < i; ++k)
if (val == k && get_sumf(k) == i)
printf("%d %d\n", i, k);
}
return 0;
}

Exactly which part do you need help with? What code do you have in place so far? What doesn't work?

how can I insert these informations:
"Number of amicable number less than 1000 is 1."
"Number of amicable number less than 10000 is 5."
like this:
"220 and 284 are amicable numbers.
Number of amicable number less than 1000 is 1.
1184 and 1210 are amicable numbers.
2620 and 2924 are amicable numbers.
5020 and 5564 are amicable numbers.
6232 and 6368 are amicable numbers.
Number of amicable number less than 10000 is 5."
.
I can only write these numbers like:
220 284
1184 1210
2620 2924
5020 5564
6232 6368
....
....
Please help me

int nBDiff = GetBValue(crTo) - nBOrg;
int nHeight = rItem.Height();
for (int nLine = 0; nLine < nHeight; nLine += 2)
{
int nRed = nROrg + (nLine * nRDiff) / nHeight;
int nGreen = nGOrg + (nLine * nGDiff) / nHeight;
int nBlue = nBOrg + (nLine * nBDiff) / nHeight;
pDC->FillSolidRect(CRect(rItem.left, rItem.top + nLine, rItem.right, rItem.top + nLine + 2),
RGB(nRed, nGreen, nBlue));
}
}
else // simple solid fill
pDC->FillSolidRect(rItem, crFrom);
// text & icon
rItem.left += PADDING;
rItem.top += PADDING + (bSelected ? 1 : 0);
pDC->SetBkMode(TRANSPARENT);
CString sTemp;

Wouldn't you think your question would be better suited here?

Only a thought: can you use a predesigned editor? you can always attach the scintilla DLL inside your project and then you would have a lot of power without almost effort inside your app.
Hope this helps.

You need to provide index of item to add. Can you show code you are using ?
|
|
|
|

Sure master!
but if i use the listview count and then according the last count i add one in the count and then try to put in the listview is it ok ?

You can do something like this as per your needs...
LV_ITEM lvitem;
int nIndex = -1;
lvitem.mask = LVIF_TEXT;
lvitem.iItem = i;
lvitem.pszText = "";
lvitem.iSubItem = 0;
lvitem.state = 0;
nIndex=m_ListCtrl .InsertItem(&lvitem);
i++;
CString str;
str.Format("%d",i);
m_ListCtrl.SetItemText (nIndex,0,str);
Somethings seem HARD to do, until we know how to do them.
