#include <iostream>
using namespace std;
void main(){
const static int threshold(5);
for(int i(1), d(+1); i; i += d, d = (i == threshold)? -1 : d){
for(int j(0), end(i); j != end; ++j) {

}
Getting rid of the ending space are trivial and left as an exercise  .

I am tying to figure out and start small on retrieving hardware information.
I am making a very simple program that does this:
1.) Find processor information
2.) Write found information to a log file ".txt"
3.) Display the found information on the screen
Very simple right? So I found this Win32 Processor Class at:
Win32 Processor Class
What I dont understand is how to implement this. On the website it does not say how to utilize this code. If it does, I do not see the example that is being displayed. I just see the breakdown of the Win32 Processor class and not a typical usage scenario.
So if anyone can please provide me some clarification on how to utilize this class correctly please respond back to this with what bits of information I have failed to recognize.

the example you point to is using a technology called WMI - Windows Management Instrumentation .. some examples on general WMI are here :- http://msdn.microsoft.com/en-us/library/aa394558(VS.85).aspx[^]
they might help you get going - WMI exposes a lot, but I dont think its necessarily the easiest of technologies to use/start with - others may disagree.
If I can find another starter for you I'll post back

The class you saw is WMI class, i prefer to use that.
The usage of class is mentioned in link itself, just check this(http://msdn.microsoft.com/en-us/library/aa390423(VS.85).aspx)
It is WMI so you need to handle like a COM.
Well try that, else you can go for suggestion from Rejeesh.

Ok,
So after looking at doing this I feel I need to use WMI (Windows Management Instrumentation).
Now to make sure I understand this, WMI is a tool that windows uses to read hardware information very accurately?
Now back to the programming portion. In order for me to use Win32_Processor Class, I first have to initialize CoInitilizeEx and CoInitilizeSecurity? I am a little confused about this. The COM (Component) is a library, and this library tells WMI and the Win32_Processor Class how to communicate with hardware?
Just making sure I understand everything and trying to put everything together.

WMI is very useful, It is used because of its high performance, and its extensible event mechanism. It can used to get information of remote systems using DCOM. WMI can be used to define a permanent consumer for a event.
It works like a query, you can write the syntax of SQL to retrieve the system information.
eg:- "SELECT * FROM Win32_Process WHERE WorkingSetSize >= 10000"
This can queried from many languages.
Now to make sure I understand this, WMI is a tool that windows uses to read hardware information very accurately?
I know WMI is accurate, but dont know whether APIs are not. 
Just read the WMI architecture, http://msdn.microsoft.com/en-us/library/aa394553(VS.85).aspx.
and read the various COM API that can be useful
http://msdn.microsoft.com/en-us/library/aa389276(VS.85).aspx
I am sure your doubts are no longer going to sustain.

Hi everyone:
I´m just starting with visual c++ 2008 and have put some code for showing a window, the code don't send any error message... the thing is that when i run it, it don't show at all... can someone help please??
thanks!!
Code:
#include <afxwin.h>
class COurApp: public CWinApp
{
public:
virtual BOOL IntInstance();
};
class COurWnd: public CFrameWnd
{
public:
COurWnd()
{
Create(0,L"Ventana con MFC");
}
};
BOOL COurApp::IntInstance(void)
{
m_pMainWnd=new COurWnd;
m_pMainWnd->ShowWindow(m_nCmdShow);
return TRUE;
}
COurApp AnApplication;
|
|
|
|
|
Use the MFC app wizard. Seriously. It's not worth dinking around with it manually.
|
|
|
|
|
Check the function name InitInstance(). If it is misspelt, there will be no window.
|
|
|
|
|
As sthalasayanam told, if everything is correct and you are able to build the project successfully, then definitely the problem is with 'misspelled InitInstance'

Ups.... That was it.... thankyou very much pals! problem solved XD

Hi. I'm porting some projects which were orignally built using VC98 (part of Visual STudio 6) to VS2008. So that we can get rid of VS 6 and have everything under VS2008.
Some of the projects are ATL & MFC projects, which apparently is just fine under VS 6, but not in VS2008.
Some of the projects, I have been able to port by removing the MFC includes from the stdafx.h and just including <atlstr.h> where they just needed support for CString.
But some are more MFC intensive. Here's the stdafx.h includes from one:
#include <afxwin.h> // MFC core and standard components
#include <atlbase.h>
extern CComModule _Module;
#include <atlcom.h>
This configuration throws C2065 Undeclared Identifier, C2133 Unknown Size, and C2512 No appropriate default constructor errors. (I guess it can't find the ATL classes.)
If I change the configuration to:
#include <atlbase.h>
extern CComModule _Module;
#include <atlcom.h>
#include <afxwin.h> // MFC core and standard components
I get Error 1 fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h> c:\Program Files\Microsoft Visual Studio 9.0\VC\atlmfc\include\afxv_w32.h 16 editclm
error.
Help is greatly appreciated.

Hmmm... So I guess this is really a hard thing...

I need to implement simple license control in B2B software (SW). My SW should be able to count the number N of simultaneously running instances of SW over current intranet and exit the process in case when N is greater than the number of purchased licenses. So that N would be the maximum number of simultaneously running instances of SW over the intranet.
I convinced that there should be existing solution to this problem (library or smth. like that) but I couldn't find any neither in internet nor at codeguru.
Could anyone suggest anything that could be useful for me?
Thanks in advance!

Dear all,
I have created a dialog application using Visual C++ 2008 with a menu and I haven't been able to get a check mark to show on a menu item.
In the class derived from CDialog, I declared a private member:
CMenu m_menu;
The menu IDR_MENU1 was loaded into the dialog using the resource editor.
In the OnInitDialog function of the same class:
m_menu.LoadMenuA(IDR_MENU1);
When the user selects the menu item, the check should appear. The code reached after selecting the menu item:
UINT j = m_menu.CheckMenuItem(ID_HELLO_CHOICE1, MF_BYCOMMAND | MF_CHECKED);
The value of j is 0 after being executed the first time and 8 after being executed the second time, which is what I expected. However, I still see no check mark next to the menu item. How can I get the check mark to show?
Any suggestions and help are appreciated.
Regards,
Mike

Dear all,
I've just found an answer (funny how this happens just a few minutes after I post the question).
In the class derived from CDialog, I changed m_menu to:
CMenu *m_menu;
In OnInitDialog, I replaced the LoadMenuA statement with:
m_menu = GetMenu();
It worked!
Regards,
Mike

Hi,
Does anyone know how to add a custom icon to an AfxMessageBox? I'm currently using the following line but would like to use my own icon instead of the canned ones.
AfxMessageBox("Thank you, now continuing.",MB_ICONINFORMATION);
I'm using Microsft Visual Studio C++.
Thanks!

Hi everyone, I was wondering if you guys could help
me out on how I should go about building this function in main
to be able to search through binary tree class(it's actually called
BinarySearchTree and is virtual from a TreeNode class, but that isn't really important).
So here is the code for BST.h that I'm trying to build the function for:
in BST.H:
typedef void (*FunctionType)(TreeItemType& anItem);
some ways BST.h uses FunctionType are...
virtual void preorderTraverse(FunctionType visit);
TreeItemType is a ADT from another class called keyeditem who's node is
of the int datatype.
I need to write a function in main to be able to work with the BST traversals.
I'm using Microsoft visual studio for the solution.
Thanks in advance!

To my knowledge, a binary search tree (BST) can be traversed (e.g., searched) in four different ways: pre-oder, in-order, post-order, and level-order. Other ways may exist but these are at least the most popular.
While not a direct answer to your question, I'll offer this just in case it may help. I have a very basic "binary tree" project that I refer to on occasion. Its preorder() traversal function looks like:
void preorder( node *n )
{
cout << n->data << endl;
if (n->left != 0)
preorder(n->left);
if (n->right != 0)
preorder(n->right);
}It is called from main() and is passed the address of the root node.

Thanks for your quick response.
Unfortunately, I don't think that your solution works with mine.
I tried implementing it, but the your node(in your code) behaves differently from mine.
Mine is actually called a TreeNode, and its members are private, so I can't access them.
Here, I'm going to post all of the code:
IN BST.H:
#include "TreeException.h"
#include "TreeNode.h"
typedef void (*FunctionType)(TreeItemType& anItem);
class BinarySearchTree
{
public:
BinarySearchTree();
BinarySearchTree(const BinarySearchTree& tree)
throw(TreeException);
virtual ~BinarySearchTree();
virtual bool isEmpty() const;
virtual void searchTreeInsert(const TreeItemType& newItem)
throw(TreeException);
virtual void searchTreeDelete(KeyType searchKey)
throw(TreeException);
virtual void searchTreeRetrieve(KeyType searchKey,
TreeItemType& treeItem) const
throw(TreeException);
virtual void preorderTraverse(FunctionType visit);
virtual void inorderTraverse(FunctionType visit);
virtual void postorderTraverse(FunctionType visit);
virtual BinarySearchTree& operator=(const BinarySearchTree& rhs)
throw(TreeException);
protected:
void insertItem(TreeNode *& treePtr,
const TreeItemType& newItem)
throw(TreeException);
void deleteItem(TreeNode *& treePtr, KeyType searchKey)
throw(TreeException);
void deleteNodeItem(TreeNode *& nodePtr);
void processLeftmost(TreeNode *& nodePtr,
TreeItemType& treeItem);
void retrieveItem(TreeNode *treePtr, KeyType searchKey,
TreeItemType& treeItem) const
throw(TreeException);
void copyTree(TreeNode *treePtr, TreeNode *& newTreePtr) const
throw(TreeException);
void destroyTree(TreeNode *& treePtr);
void preorder(TreeNode *treePtr, FunctionType visit);
void inorder(TreeNode *treePtr, FunctionType visit);
void postorder(TreeNode *treePtr, FunctionType visit);
TreeNode *rootPtr() const;
void setRootPtr(TreeNode *newRoot);
void getChildPtrs(TreeNode *nodePtr,
TreeNode *& leftChildPtr,
TreeNode *& rightChildPtr) const;
void setChildPtrs(TreeNode *nodePtr,
TreeNode *leftChildPtr,
TreeNode *rightChildPtr);
private:
TreeNode *root;
};
in TreeNode.h:
#include "KeyedItem.h"
typedef KeyedItem TreeItemType;
class TreeNode
{
private:
TreeNode() {}
TreeNode(const TreeItemType& nodeItem,
TreeNode *left = NULL, TreeNode *right = NULL)
: item(nodeItem), leftChildPtr(left),
rightChildPtr(right) {}
TreeItemType item;
TreeNode *leftChildPtr, *rightChildPtr;
friend class BinarySearchTree;
};
in keyeditem.h
typedef int KeyType;
class KeyedItem
{
public:
KeyedItem() {}
KeyedItem(const KeyType& keyValue)
: searchKey(keyValue) {}
KeyType getKey() const
{ return searchKey;
}
private:
KeyType searchKey;
};
Thanks again for the quick response.

While not complete, I came up with something like:
void MyCallback( TreeItemType& anItem )
{
cout << anItem.getKey();
}
void main( void )
{
BinarySearchTree bst;
TreeItemType key(1);
bst.searchTreeInsert(key);
bst.preorderTraverse(MyCallback);
}
