I m using vs 2008 c++ compiler try to compile my code and it is giving error #error : MFC requires use of Winsock2.h.
in that file in which i used socket API.
c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\ATLMFC\INCLUDE\afxwin.h(84) : fatal error C1189: #error : MFC requires use of Winsock2.h
Using VS2013, in the following code sample, I have the repeated alternation "(?:(a)|(b)|(c)|(d))+"
#include <regex>
std::smatch match_pieces; std::string text = "acbd"; std::regex pattern("(?:(a)|(b)|(c)|(d))+"); std::regex_search(text, match_pieces, pattern);
Trying to match this to the string "acbd", produces the following matches.
0: acbd
1: a
2: b
3: (unmatched)
4: d
Where as the expected result would have been:
0: acbd
1: a
2: b
3: c
4: d
Is this a bug as i don't understand what is the match strategy here ... ?
Thanks

http://msdn.microsoft.com/en-us/library/windows/desktop/aa383745%28v=vs.85%29.aspxHi Experts,
I am a fresher in vc++. We want to generate dynamic resource file for VC++ where the data will come from database (Oracle).
For an example,
When a user log in the system, at that time if User is an English User, then some data in english language needs to be loaded in vc++ resource file. If the user is French then French data will be loaded into the resource file.
Right now all the data are hard-coded in the resource file but we want to load it dynamically from database, based on the login-user language.
Can you please suggest any idea/concept how to do this dynamic implementation as I am not able to find any such concept in google.
Hi
I have a main.cpp, a GradeBook.cpp and a GradeBook.h.
I am using Microsoft visual studio 2010. I have made a win32 console application and I have added my .cpp files in 'source files' and my .h file in 'Header Files' but there is some warnings and errors:
d:\mitra\c++examples\chapter2\chapter2\gradebook.cpp(3): warning C4627: '#include <iostream>': skipped when looking for precompiled header use
1> Add directive to 'StdAfx.h' or rebuild precompiled header
d:\mitra\c++examples\chapter2\chapter2\gradebook.cpp(6): warning C4627: '#include "GradeBook.h"': skipped when looking for precompiled header use
1> Add directive to 'StdAfx.h' or rebuild precompiled header
d:\mitra\c++examples\chapter2\chapter2\gradebook.cpp(35): fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "StdAfx.h"' to your source?
Note that:
I would appreciate any step by step instruction to do with my own classes, when I want to separate them into two file (a .h file and a .cpp file) for further use!
Thank you so much

}Above you can see my whole project to make a bank machine.
The problem is with all the read and write command to write and read in files. The information inside the file did not change. I think the program did not even make the files. anyone can help me please and tell why the program did not make any files and if the program made the files why the the infomation inside the files didnot change even after I write inside it some information. btw the program work but the information inside the files is the only problem. Can you please help me as fast as you can because I really need the program to be perfect and I need to give to my doctor in 30 hours so Please help me :).
Hello folks,
I have an application issue where I permit the User to resize a Dialog Box based on a Font selection.
I am having some difficulty in thinking through what else I need to manage.
I want to enable scrolling of the Dialog itself.
In order to do so, I need to know the "real" size of the Dialog Box.
If I use GetClientRect or GetWindowRect, I will get the size that appears within the CFormView.
For example, suppose that the physical screen is 5 by 5.
I can end up with a dialog box that is 10 by 10.
Then I want to be able to show a scrollable dialog box in the 5 by 5 area.
Does that make sense?
If I load the dialog box now, I will only be able to view the 5 by 5 area, and if I issue GetClientRect, I can only see 5 by 5.
I checked my Main Frame, and it does not clip children.
If I use some silly values inside my scroll logic, I can actually scroll through the dialog. Which suggests this is doable.
But, what I'd really like to be able to get is the real Dialog Box size, not just the viewable area from the display.
Is this possible?
Thanks and Happy New Year!

I have an MFC program that was compiling and running in a trial version of VS 2012 with no issues. When the trial ran out I purchased but was only offered VS 2013. The same project compiles with no errors ( I am using MBCS support downloaded separately). The problem is when running or debugging it fails to load a dialog ( call to doModal() ).
CMFCLaserALTDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
it returns with -1
Any ideas? Why is this specific to VS 2013 and not VS 2012? Since my VS 2012 trial ended I can lo longer run VS 2012 :(
Thanks in advance for your help,
**** EDITED ****
When I step into the code, at m_pMainWnd = &dlg I find dlg == NULL. Why would this work in VS 2012 but not in VS 2013? I'm suspecting that when VS 2013 opened my 2012 project the first time the automatic conversion to a VS 2013 project setting changed something I'm not aware of...
~Thanks,
Hello,
I have VS C++.net 2003 academic v. success on a (slow) windows XP computer (fine) but tried to use this on a Windows 7 (intel i5) computer but there were incompatibilities. So I paid an expert to suggest some modifications which enabled
it to install. However, the entire Properties pages for MFC were missing. Also, recently the conhost.exe reported an access violation (how come? they changed Windows 7 console system?) so that doesn't work. OK, so I reinstalled it on an old XP computer
(fine). I guess the 2003 version just isn't going to work on my Windows 7 machine.
But I would like to use a console version of C++ on my Windows 7 computer so I downloaded Visual Studio C++ Express 2010 (I already have 2010 Express C# on it which worked fine). The C++ Express 2010 installation worked and I recompiled and executed my simple program. But (overnight) now rebooting, a C++ Express 2010 icon or option does not exist; however there are logs of the installation. No way to instantiate C++ 2010 Express now. I should say, I did not (yet) remove the installed old 2003 C++. I would be happy to just get the C++ Express 2010 version to work.
As a second question, during search for options I downloaded VS2012_WDX_ENU.iso and burned a DVD. But I don't find any reference to indicate what this is for or how to use it. I assumed maybe that this was an express 2012 version, but maybe not. It would be helpful to have more info on what these various products are for.
Hi,
I am using Visual studio 2010 for my c++ application. I was initially a C# developer and hence would love to get similar and at least some ease in memory management. Right now there are too many delete operators in my project.
Whats the best way of handling memory efficiently and effortlessly in native C++.

Hi,
I have a program that runs well except in one customer's computer.
This problem will not cause crash so I can't get a dump file, is there any way to get the call stack information in his computer?
I tried windbg, but the process is hang up when I attach my program to windbg.
Could anyone help about this?
Any suggestion will be appreciated.
All Regards
I have a set of managed dll's that work fine as a managed standalone program. But, I'm trying to use them from an un-managed application. When I do, once I've returned from calling my managed functions, if I wait a while, the program will crash with "access violation attempted to read or write protected memory". I have a messagebox that pops up with some information about a returned value. If I just sit there with the message box displayed, after a few seconds the exception will happen, so I guess this points to garbage collection.
After the exception, there is no information about where this is happening. Any ideas about tracking this down, or preventing it, or ignoring it?
Hello!
I am very new to programming and I am at having problem with a school project where I am trying to make a struct that will hold a winner's name aswell as the year the winner won and I am trying to make this struct into a dynamic array so that it can hold a given number of winners. At the beginning of the program I want to be able to type in how many winners that this struct array will be able to hold and then change the struct array's size to that value. I have no idea how to go at this and any help would be much appreciated. Please try explaining very simple :)
Here is the code so far:
struct winnerInfo {
char name[20];
int year;
};
int main(void){
int antalÅr;
printf("Hur många år vill du hantera?\n");
scanf("%d", &antalÅr);
printf("\n");
struct winnerInfo info[antalÅr];
flush(stdin);
getchar();
}Using the recommended PowerRegisterSuspendResumeNotificationI registered my service for resume and suspend notifications. These events are received correctly when sleep or hibernation is used. The resume and suspend events are also correctly received in a console application which uses the same code, but if the code is in a Windows Service, active standby events are not received.
The two projects (the console app and the service) can be found here:
https://dl.dropboxusercontent.com/u/50537873/StandbyDetectionService.zip
To me this appears to be a Windows bug. If there is a way to receive the suspend and resume events in windows services, please let me know.

Here is the code:
event_triggered = WaitForMultipleObjects(
EVENT_ARRAY_SIZE,
mp_common_data->event_array,
WAIT_FOR_ANY_EVENT,
WAIT_TIMEOUT_VALUE );
event_1 = (unsigned int) mp_common_data->event_array[0];
event_2 = (unsigned int) mp_common_data->event_array[1];
event_3 = (unsigned int) mp_common_data->event_array[2];
if( event_triggered == (DWORD) 0xFFFFFFFF )
{
last_error = GetLastError();
}mp_common_data is a pointer to a structure, declared in part as:
HANDLE event_array[ EVENT_ARRAY_SIZE ];
unsigned int count_of_start_events;
unsigned int count_of_stop_events;
unsigned int count_of_exit_events;
unsigned int count_of_timeout_events;
For completeness, EVENT_ARRAY_SIZE has a value of 3, the size of the array. WAIT_FOR_ANY_EVENT is a BOOL set to FALSE. WAIT_TIMEOUT_VALUE is set to 10,000 for a ten second timeout.When the cursor is hovered over the argument mp_common_data->event_arrayit shows item event_array with a plus sign. Moving the cursor there expands the array showing the three elements. In this run of the program the values are 0x128, 0x12c, and 0x130. Using the debugger these are the values put in the array in another part of the application.
However, the integers event_1, 2, and 3 all show a value of 0 (zero). That explains why the return value of the wait API 0xffffffff. GetLastError() returns 6 which says invalid handle. Given that event_1 through 3 only get zero, that fits. So why do they get zero rather than the values 128, 12c or 130?

Greetings everyone,
this is my first post in this forum, so nice to meet you all.
Now for my question:
I just start to learn MFC, so I am a complete newbie. Before my question, I have to inform you that I created this project without MFC application wizard, just an empty project. This was instructed by my lecturer. I am able to create the initial main window, but I am stuck there for a long time now. Here is my code:
#include "MainMenuWindow.h" // application class
#include <afxwin.h>
// constructor initializes the window
MainMenu::MainMenu()
{
// Create Window with Title Bar
Create( NULL, // default CFrameWnd class
CString("Main Menu"), // window title - convert char array to CString
WS_OVERLAPPEDWINDOW, // full-featured window
CRect( 0, 0, 1366, 730 ) ); // screen coordinates left top right bottom
// add menu and submenu dynamically
Option.CreateMenu();
PopupOption.CreatePopupMenu();
// Add items to the sub menu and menu
PopupOption.AppendMenuW(MF_STRING, ID_INSERT_OBJECT, CString("Insert Object"));
PopupOption.AppendMenuW(MF_STRING, ID_OBJECT_CONTENT, CString("Content"));
PopupOption.AppendMenuW(MF_STRING, ID_EDIT_OBJECT, CString("Edit"));
PopupOption.AppendMenuW(MF_STRING, ID_DELETE_OBJECT, CString("Delete object"));
PopupOption.AppendMenuW(MF_STRING, ID_SAVE_FILE, CString("Save"));
PopupOption.AppendMenuW(MF_STRING, ID_LOAD_FILE, CString("Load"));
PopupOption.AppendMenuW(MF_STRING, ID_QUIT_WINDOW, CString("Quit"));
PopupOption.AppendMenuW(MF_STRING, ID_DISPLAY_OBJECT, CString("T - Display Object"));
Option.AppendMenuW(MF_STRING | MF_POPUP, (UINT)PopupOption.m_hMenu, CString("Option"));
SetMenu(&Option);
}
// destructor releases resources
MainMenu::~MainMenu()
{
}
afx_msg void MainMenu::InsertObject()
{
//MessageBox(CString("This is InsertObject window"),CString("Insert Object"));
}
This is just part of my code (not all my code I must admit, I take reference from other website), without including the mainwindow.h file and mainwindowapp.cpp. With this, I am able to create an initial main window with a menu bar, and that's it.
I try to make sub window appear when I choose an option from the window menu, and only the messagebox that I commented above work fine.
Take the insertobject() above as example, when I choose this option in the menu bar, I am hoping to get a subwindow which let user choose an shape object and select its size, then it will draw the shape on the main window. I imagine the subwindow should have some static text, drop down list and buttons.
I try the cdialog function, but generate an error.
I try putting another window create code inside insertobject() function, got another error:
// Create Window with Title Bar
Create( NULL, // default CFrameWnd class
CString("Insert Object Menu"), // window title - convert char array to CString
WS_OVERLAPPEDWINDOW, // full-featured window
CRect( 0, 0, 500, 500) ); // screen coordinates left top right bottom
If you need more information, I am able to draw shape object on main window:
afx_msg void MainMenu::OnPaint()
{
PAINTSTRUCT ps;
pDC = BeginPaint(&ps);
//MainMenu::DrawDiamond();
//MainMenu::DrawSquare();
//MainMenu::DrawTriangle();
EndPaint(&ps);
}
So to summarize this, how do I code my program so that a sub window will appear, let user select an object, then draw that object on the main window?
Furthermore, is there any MFC tutorial without using MFC application wizard? Most of the tutorials I found on the internet include using the wizard, so it's not suitable for me.
Lastly, thank you for anyone who read this long post. Since this is my first post, I hope my question is as clear as possible. And pardon my bad English. Thanks!
I was wondering what is the best strategy for enumerating device id's for hardware for a new project
I have seen some code for a device manager like project, but I was more interested in a simple table that can be evaluated in code
