That line of code looks fine. without looking at the rest of the code around it I don't know for sure.

By the way, if the array is always made up of 65536 doubles, then why not,
double m_str[65536];
It's much faster and you don't have to worry about freeing it later.

Are you using SSE or SSE2 by any chance? If you are, I might answer your question.

When we capture an image, it goes to clipboard. I heard that clipboard accepts DIB and TIFF format(but I'm not sure). If I send JPEG image to clipboard, does clipboard transform JPEG image to DIB or TIFF?
|
|
|
|
|
CF_BITMAP, CF_DIB, and CF_TIFF are three of the standard formats. To register others such as JPEG, you'll need to call RegisterClipboardFormat().

I have an array:int amounts[]
How do I define size of arrays as an enumeration literal
Num in an anonymous enumeration?
|
|
|
|
|
Typically when I need to do this I have:
enum Test
{
Item 1
Item 2
.
.
.
Item N
TestEnd
}
then I just use (TestEnd - Item 1) for the size on the array. Just make sure that if you add to the enumeration that TestEnd or whatever you call it is always the last item. This will create a proper sized array.

Here is my code:
Can you help me?
#include <iostream>
using namespace std;
const NUM = 2;
int volumes[NUM], volume;
int count=0;
int amounts[NUM],amount;
const double price=0.05;
const double fee=12.0;
int main()
{
do
{
cout<<"Please enter the volume of water used by a customer ";
cout<< "during a month (in gallons).(Zero to end):";
cin>>volume;
if (volume==0.0)
break;
if (count==NUM)
break;
volumes[count++]=volume;
amount=(volume*price)+fee;
amounts[count++]=amount;
}
while(true);
return 0;
}

// include <float.h> and <iostream> in stdafx.h
#include "stdafx.h"
using namespace std;
const NUM = 2;
// changed int to double because volume usually isn't in whole numbers
//int volumes[NUM], volume;
double volumes[NUM], volume;
int count=0;
// use double for amounts because you are using doubles to multiply
double amounts[NUM],amount;
const double price=0.05;
const double fee=12.0;
int main()
{
do
{
cout<<"Please enter the volume of water used by a customer ";
// cout won't get you the value must use cin
//cout<volume;
cin="">> volume;
// with doubles never check for equality, check for greater or
// less than
if (volume < DBL_MIN )
break;
// move this check to the end of the while loop
// and make it check for >= instead of ==
//if (count==NUM)
// break;
// also you are incrementing count twice. only do it once
//volumes[count++]=volume;
amount=(volume*price)+fee;
//amounts[count++]=amount;
volumes[count] = volume;
amounts[count] = amount;
count++;
if( count >= NUM )
break;
}
while(true);
return 0;
}

Thanks for the comments. It helps a lot.
One more question:
I am trying to display all values after user enters 0. I wrote the following code. I can't see what is incorrect in this code.
displayArray();
void displayArray(const int volumes[NUM];const int NUM)
{
count<<"\n";
int count=0;
while (count
|
|
|
|
|
Also don't forget to predefine the function unless you put the fuction code before main.
displayArray( volumes, count);
// First the Function declaration is incorrect.
// you have a semicolon where there should be a comma
// and you have volumes declared as int when it should be
// double but that was covered previously
// also you don't need NUM as a variable because it is a
// program constant. Instead pass Count
//void displayArray( const int volumes[NUM]; const int NUM)
void displayArray( const double volumes[NUM], const int Count)
{
cout<<"\n";
int nCount=0;
while ( nCount < Count)
{
cout<< volumes[nCount] << " ";
nCount++;
}
int nPause;
cin >> nPause;
}

Hello, everyone!
How to dump some debug information (I mean the information of my special program information, for example, the value of a variable which I am interested in) to VC 6.0's debug window in a MFC project? Who can show me an example?
Thanks in advance,
George

afxDump << nVar;
afxDump is the stream that outputs to the debug window in the Visual Studio IDE. It works in both 5.0, 6.0 and .NET.

Search MSDN for the TRACE() macros.

A good utility for using the trace functionality in your application so that you can also send to a different viewer (for more real time debugging) go here http://www.dilascia.com/
and get the Trace Win app.

Hy,
i hope somebody can help me to solve my problem.
I have a laptop and a lan network at my company and a lan network
at home.
At home i have a static ip address for my laptop ,
at company the ip address is given dynamicly.
I would like to write a little tool to change the ip address
and the setting how to receive the ip address,
to make the change more comfartable for me.
I know there exist some tools to do exactly this, but i want to
solve this problem on my own.
Now i am searching for examples or the orders to implement my tool,
because i do not find them until now.
I am very thankful for every advice.
Thanks
Micha

What is the purpose of changing dynamic IP?
In any case, you may consider creating local DNS mapping just by opening and writing/modifying new entry in "Hosts" file located in yours WINDOWS\SYSTEM32 directory. Make sure to do that before loading/calling any winsock/wininet functions in your program.

I have a Video system and I want to display permanently images that come from it when I run my application. Solution seems to be Direct Draw with 2 graphic board or a DUAL one. It is not really a problem, I suceed. But, there is a point that worry me. It is obvious that when my application is running on one monitor we will display video image and on the other normal interface and I'd like seeing mouse only on the normal inteface. But if we attach all the graphical boards to the desktop the mouse is moving on the 2 screen, I am afraid that is too confusing for customer. I'd like then use one board attach on the desktop (we need at least one anyway) and the other is sleeping, excepted when my application is running then it will display video. In term of programing that means we need to call Direct draw with the good board device. the function DirectDrawEnumerateEx is all what we need. It works well if all the board are attached to the desktop (that is to say we see all the board device) but any of the boards are not attached then I don't succeed in seeing them. However there is a flag DDENUM_DETACHEDSECONDARYDEVICES that seems to be specially provided for that use but it do not return anything about the detached devices. Is anyone can help?
