That sounds like a neat assignment. Just out of curiosity, what grade level are you in?

BTW, there are more possible sums than what you list.

Best wishes,

Luckily I'm not a student. I guess that if I was I had the answer because it sounds like a school assignment. I'm a shame to admit that when I was this question was introduced to me I started to write it using a recursive function, but I got stuck because it started to be too complex. It was then that I thought there must be a simple (school) solution for this, as this is an academic riddle (just like the traveling salesman). I thought mayeb someone here has the insight...

Incase someone interested, here is a simple solution. I have no idea why I got stuck from the first place:

<br />
BOOL IsSum(const CUIntArray& Array,UINT Sum) const<br />
{<br />
	for(int i=0;i < Array.GetSize();i++)<br />
	{<br />
		if(Array[i] == Sum)<br />
			return TRUE;<br />
		else if(Array[i] < Sum)<br />
		{<br />
			if(CheckSum(Array,Sum,i,Array[i]))<br />
				return TRUE;<br />
		}<br />
	}<br />
	return FALSE;<br />
}<br />
<br />
BOOL CheckSum(const CUIntArray& Array,UINT Sum,int nIndex,UINT SoFar) const<br />
{<br />
  for(int i=nIndex+1;i < Array.GetSize();i++)<br />
 {<br />
   if((SoFar+Array[i]) == Sum)<br />
     return TRUE;<br />
   else if((SoFar+Array[i])<Sum)<br />
   {<br />
      if(CheckSum(Array,Sum,i,SoFar+Array[i]))<br />
         return TRUE;<br />
   }<br />
 }	<br />
 return FALSE;<br />
}<br />

Hi I have one enquiry. I am a novice in mfc. Using one listbox. In that sometimes I have less data, some times lot of data. Depending on that the scrollbar comes automatically. So my enquiry is that is there any way to know the presence of scrollbar in the listbox? If so how to do that ? Any suggession will be highly helpful.

Use GetScrollBarInfo. Refer SCROLLBARINFO-->rgstate.
Your code would be something like this,

SCROLLBARINFO info;
GetScrollBarInfo(OBJID_VSCROLL,&info);
if (info.rgstate[0] & STATE_SYSTEM_OFFSCREEN)
{
  //vertical scroll bar is present for window, but is not displayed
}

How to get PID / Process Name from Task Manager

Hi,
I am trying to kill process from task manager using "End Process" in "Processes" tab. But I tried to get the handle / PID of the process that I have selected to terminat. I would like to know how to get the handle / PID of the process that I am trying to terminate.
I tried to use TerminateProcess API to handle this. But I am not able to get handle for the killing process (e.g. winword.exe).

Anything on this will help.

Thanks

how to convert the string type into double type? (vs 2005)

double GetInvestmentAmount()
{
Console::Write(L"How much money do you want to invest? ");

String^ input = Console::ReadLine();
double amount = \\ i want to convert the 'input 'into the double type
return amount;
}

how can I convert the " String ^ input" into the double type. Thanks in advance.
I've tried "safe_cast<double>(Console::ReadLine())" and " Covert.ToDouble(*input)" but it just doesn't work ==

define preprocessor constants string in command line

marmooooo6-May-07 23:06

6-May-07 23:06

Hi,
I want to define preprocessor constants in command line.
In source it would be something like this:
#define STR_SOMETHING "something"

Now how can I get the same result in command line using /D?
I tried in VS 2005, in Project Property Pages->Configuration Properties-> C/C++->Preprocessor-> Preprocessor Definitions…
Adding STR_SOMETHING=”something” doesn’t work. In Command line it looks like this:
/D "SOMETHING="something"".
The problem is with "".
Any idea how to do this?

Are you sure? On my system (VS 2003) It doesn't work. Moreover (excerpt from MSDN):

"With one exception, defining symbols and constants with this option has the same effect as using a #define preprocessor directive at the beginning of your source file. If you use /D, quotes on the command line will be stripped whereas they are retained in a #define statement."
