-service session (wininit.exe...)
-User session (winlogon.exe ...)
Now i want to create a new session inside MyService.exe .
Can you share with me document or ebook ?
wininit.exe
---------services.exe
-------------svchost.exe
-------------MyService.exe
explorer.exe
------- chrome.exe
wininit.exe
---------services.exe
-------------svchost.exe
-------------MyService.exe
----------------wininit.exe
-------------------services.exe

This is really a Google question, it has nothing to do with C++.

Hello,
I have a need to create a C++ non-dotnet DLL that will be called and used by a VB.net application. I am trying to determine the type of DLL to create. The DLL will contain some classes, variables, and functions that I will be writing. I understand that there are three types of a DLL that can be created: 1) Regular DLL - Statically Linked to MFC, 2) Regular DLL - Dynamically Linked to MFC, and 3) DLL that uses the Standard Windows Libraries, non-MFC.
My question is, which would be the best to use, one that is linked to the MFC, or one that uses the standard windows libraries? Can someone make a suggestion and explain the differences between MFC and the standard libraries?
Thanks!
Gary

Given that you are calling it from VB.NET, unless you want to go through p/invokes, might I suggest looking into C++/CLI? This gives you what you want and accesses both managed and unmanaged stuff.

David,
Thanks. I'm not sure that will meet my needs. The DLL needs to be a truly compiled DLL and not part of the .net libraries. Are my assumption correct that if I use C++/CLI, it makes it a C++.net DLL?
Again, thanks.
Gary

In a C++/CLI DLL you can decide on class level whether you want to make it an unmanaged class (wich I think you mean with truly compiled) or a managed (.Net) class. You could create the business logic in unmanaged classes and provide a managed interface/wrapper for the VB.Net classes to call directly.
The good thing about pessimism is, that you are always either right or pleasently surprised.

I would suggest option 3, a standard C-style DLL. Your VB.NET code can then access the functions through the P/Invoke mechanism[^].

#include<stdio.h>

void main()
{
cout<<"cout is executed"<

This is most probably a result of buffering of the output streams. I would bet that depending on the scenario/platform/compiler you could get different results with this very same code. Don't write such code or flush the streams if you want to guarantee write order.

Why are you trying to use both functions at once ? Is there any advantage ?

If you're using a standard C++ compiler then the cout should happen first. However as you're not using a standard compiler (cout and printf are members of the std namespace for a standard compiler) then all bets are off. Get a new compiler and see if you have the same problem.

What if you called "flush" at the end of each? Does it make a difference?

Hi,
I have problems with 'WindowStateChange' events in my QWidget.
I have created a simple test widget with 3 buttons, to set window state:
Normal: showNormal();
MAX: showMaximized();
FullScreen: showFullScreen();
and trace window state events (QEvent::WindowStateChange).
When I change 'normal' <-> 'max' there is no problem (altough i receive twice 'max' event), BUT when i change 'max' <-> 'fullscreen' i receive this events:
'max' --> 'fullscreen'
----------------------------
0 No State
4 FullScreen
'fullscreen' --> 'max'
---------------------------
6 Maximized
4 FullScreen
6 Maximized
2 Maximized
with code like this:
state = windowState();
if ( state & Qt::WindowMaximized )
qDebug() << state << "Maximized";
So my widget has in both cases a strange flickering. That is, when 'max' --> 'fullscreen', it has an 'intermediate' "normal" state (0), and when 'fullscreen' --> 'max', it has several 'intermediate' states...
In my application, I must show/hide things when app is normal/maximized/fullScreened, so this flickering is really a problem.
Is it possible to do anything?
Thanks in advance,
Diego

When changing states in this way it is often best to suppress window updating during the transition, to avoid such flickering.

Writing a program to compute n series of Fibonachi (Recursive and No Recursive )
I wrote this for non recursive
#include <iostream>
using namespace std;
int Fibo(int number);
int _tmain(int argc, _TCHAR* argv[])
{
int i,sum,n,a1,a2;
cout<<"enter number : "<<endl;
cin>>n;
i=3;
sum=0;
if(n==1)
cout<<"1";
else if(n==2)
cout<<"1,1";
else
{
cout<<"1 ,1 ,";
a1=1,a2=1;
while (i<=(n))
{
sum=a1+a2;
cout<<sum<<" , ";
a1=a2;
a2=sum;
i++;
}
}
return 0;
}
And this for Recursive mode
int _tmain(int argc, _TCHAR* argv[])
{
int ii=1,nn=0;
cout<<"enter number:"<<n;
cin>>nn;
while(ii<=nn)
{
cout<<"\t"<<Fibo(ii);
ii++;
}
int Fibo(int number)
{
if((number==0) || (number==1))
return number;
else
return Fibo(number-1) + Fibo(number-2);
}
buw my question how can I compare these two methods for memory usage and their speed?

How about calling time() before and after?

No its not a programming project.its about data structure lesson an I have to compute it myself.
