Well i solved the problem time being.
by declaring
extern long iSelPackageItemID in the .h file
and long iSelPackageItemID in .cpp file

i got help from here http://www.codeguru.com/forum/showthread.php?threadid=427587

But the core OOP funda remains unanswered, i know this is going beyond the scope but just for knowledge sake. I am also working in java and i haven't seen such kind of syntax, also in a desingning book it stated not to use a global variable since it voilates the basic rules of OOP. So is the above code a good programming practise...?

How are you creating "some value"? The first thing that comes to mind is that it is a variable that has gone out of scope between when you assign it and when you try to reference it.

I am not clear on this thing ... but now it looks like pretty much that it's going out of reference. My OOP fundas are weak... but just one question when i assign a value to a class member A, then i declare an obj of class B so when i try to access the member from a through B does it go out of scope..?

I'm not saying that the member itself of class A goes out of scope, I'm suggesting that what was assigned to the member went out of scope. The member itself is still good but it is referncing memory that is no longer good .You see this a lot with objects created on the stack. For example:

char *MyCreateFunc ()
{
char buffer[256]

// do all the stuff to fill in buffer

return buffer;
}

The statement
A::m_memberVar = MyCreateFunc ();

will compile and execute and may even work as expected sometimes. However, it is wrong!! A::m_memberVar remains in scope but what it points to is no longer in scope because the memory containing the data is no longer valid once the MyCreateFunc returns.

Show the code where you create the value assigned to the member of class A. The member variables of a class remains in scope until the class itself goes out of scope, so unless you're accessing class A incorrectly, the problem has got to be in the value assigned to the member variable.

I have an application in visual c++ relating to client and server. this appliaction does many types of work like getting all user names logged on to computers,remote shutdown,remote logoff, getting the remote desktop view and many others types of functioning related to "lan monitoring" through server. but for this , client application has to be executed all the time whenever any user logon through his local account.
but the problem is that I couldn't find any way to execute the "client exe" automatically whenever any user logon through his/her local account.But I could execute the client exe automatically for the administrator by making changes in the registry but I have to execute it "for all users".

So please help me to find any way to execute the client exe for all users automatically whenever they logon through their local account.Is there any win api or by making any registry changes or any program which can call the exe automatically whenever any user login.

ps:since this is all a part of a domain so all the other users are less priviliged than admin

How to get IDD of a PropertyPage dialog? [modified]

Hello, I have a property sheet that I want to check whether a specific page is Active or not. How can I get IDD of associated dialog resource in a property page I tried following code but GetDlgCtrlID() fails (returns 0). By the way I don't think it is important but anyway the property sheet is embedded in a CFormView

<br />
//in CMyView<br />
int nID = pDoc->m_sheetProperty.GetActivePage()->GetDlgCtrlID();<br />
if(nID == IDD_INTERESTING)//nID is always zero even when IDD_INTERESTING is active<br />
{<br />
...<br />
<br />
}<br />

thanks

Why does your CPropertySheet object belong to the document class rather than the view class?

Electronic75 wrote:

As it probably should be. GetDlgCtrlID() is for returning the ID of controls on dialog boxes or property pages.

I've never known it necessary to query a dialog box's ID. In any case, I'd be more inclined to compare the return value of GetActivePage() with the class objects associated with the various pages. For example:

CPropertyPage *p = pDoc->m_sheetProperty.GetActivePage();
if (p->IsKindOf(RUNTIME_CLASS(CMyOtherPage)))
    ...
else if (p->IsKindOf(RUNTIME_CLASS(CTheLastPage)))
    ...

Hi David, Well it is a MDI application that I did bizarre things to make it look nicer. eg. it has a property page embedded in a CFormView and even another CDocTemplate(Doc, View, Frame) embedded in one of the pages. It maybe bizarre but it looks good! Smile | :)

Hello all,
class A:
Function x

class B:
Function y

I have already declared object of class B in class A to access member function y of B.Now i have to access function x in class B.In fact i have to take the return value of one function of class
A and give it as input to one function of class B.Then mutally creating objects is giving errors,how to overcome the above problem.

Why not show the actual class definitions? Your paraphrased version makes no sense.

Why dont you derive one class from another so you can use the function y from class A for example?
Have you declared pointers inside each class?

Hi..
are you including header files in both classes, i mean..
in A.h

#include "B.h"

and in B.h
#include "A.h"

if u give so definately u will get errors,
so include only in the first written class .
and in secondly written class just define the first class

class A;

try this hope it works..

One project linking to files in another project

Hi,
I have a dialog based application which was initially in C:\ drive. After running the project in C:\ drive for a couple of times, I made a copy of it in the D:\ drive and when I run open the project file in the D:\ drive (clicking on the .sln file) and if I put a break point in say the OnInitDialog() of a dialog class, when I run the project, this break point
automatically goes to the same function but to the project in the C:\ drive.

Also when I try to go to the declaration of any function by pressing F12 at the function definition, an resolve ambiguity dialog is shown and the function declarations of the project in C:\ and D:\ drive are listed. In the above mentioned scenario, files names of the project in the C:\ drive are
represented in lower case (tab name in the workspace)

How do i get over this issue?
I am using VS 2003 on XP.

Make sure that for every include in your source code, you supply relative paths and not absolute paths. Check that also for all the include directories if necessary in the project options.

Hi Cédric Moonen,

After reading your reply, I created a dialog based application using the Wizard(without adding any code) and the similar behaviour as described in my earlier post is observed.
Is there any setting in VS that I need to check for??

What do you mean ? So, you created a completely new dialog Based application on the D drive. When you put a breakpoint in one of your function, it points to a source file on the C drive ? That's impossible because you don't have a similar solution on your C drive Unsure | :~

Could you explain clearly your problem ?

I create a project in the C:\ drive, run it once, then close the project.
Now make an extra copy the same project in the D:\ drive, then run this project in the D:\ drive. If I search for a string say OnInitDialog(), then in
my search result, I find that both the projects that in the C:\ and the D:\ are shown.
