Hi, My team is considering migrating Visual Studio 2013 from 2008.
I found that v120_xp switch (v110_xp in 2010) enables XP support on MSVCRT.
But I'm wondering if it only supports XP SP3 (in 32-bit), not SP2 or prior.

Most of our client still uses WinXP, some of them is still not applying SP3.

so we must support XP SP2 at least.

Which is correct? Does v120_xp switch supports only SP3? or can it be used prior SP2?

Hi All,

We have localized our software(English and Hindi) and have localized every control name, tooltip, menu items name and etc. Now I am facing the problem with Windows button (minimize, restore and close) tooltip. The tooltip for these buttons still shows in English even if Software is opened for Hindi. All other things are showing in hindi except the tooltip of these windows buttons. Please see the minimize button tooltip (in english) in mentioned image.

Please suggest me any way that How can I localize tooltip of these buttons?

I met a issue when i use CString to store some specified bytes. i created a new 'Win32 Console Application' project with VS2010, checked the MFC. My question and source 

            CString str;
            TCHAR* p = new TCHAR[31];
            p[0] = 0xFFFF; //it will not the issue later if i change p[0] = 0xFFFB.
            p[1] = _T('A');
            p[2] = _T('A');
            p[3] = 0;
            CString strP = CString(p); //Result：strP == “AA”  
 
            str.Format(_T("%s--%s"), _T("ab"), strP); //Result：str == “”， Why? It's not what i expected.  
 
            str = _T("ab--") + strP; //Result：str == “ab--AA”，It is what i expected.
             
            delete[] p;

Hi,

I need to send data from application to a "USB serial device".

Application has been developed in VC++.

Please guide me with suitable sample code on how I can do it.

Thanks in advance,

Alex

#include<iostream>
int main()
{
    const char* p = "ab中国"; //  中 = \u4e2d  国 = \u56fd
    std::cout << p << '\n';
}

1. By clicking the source file name in the solution explorer with the mouse right click and selectingOpen With >> Binary Edit, one can see that the source file is encoded in UTF-8 with signature (look at the BOM at the start of the file).
   
2. One can also see on this binary image of the file that the literal string is correct in the source code, as follows:
     a    b       中             国
   61  62  E4 B8 AD  E5 9B BD
   
   where E4 B8 AD is the UTF-8 encoding for the character 中 = \u4E2D  and E5 9B BD is the UTF-8 encoding for the character
   国 = \u56FD.
   
3. However, if you debug with a break in the expression
   
   std::cout << p << '\n';
   
   you'll verify that the character string obtained by the compiler is given by the bytes 61 62 3F 3F 00,
   which is clearly a bug.

But what is exactly the problem here? Is it that the compiler doesn't work correctly with a source file encoded in UTF-8, or might there be some other explanation?

Hi

I can not find a minimum working example of pure MFC CListBox. The closest example provided in this forum was [Working with CListBox correctly] and the example code did not even use CListBox at all, nor did it ever use the CListBox::AddString member function. 

All of the numerous examples that I found online were not complete, each one of them always left out a crucial step. It seems that the problem I am having is identical to the problem addressed in [Working with CListBox correctly], debug assertions are failing when attempting to invoke CListBox::AddString(). 

I really need a complete and minimum working example of using CListBox in a pure MFC application in Visual Studio 2008. 

The closest thing that I could find was a Visual C++ 6.0 example that used an array of six CListBoxes. This was too complex to fully understand.  

It would really be great if Microsoft provided [complete and minimum working examples] of every graphical user interface object. This would reduce several days of research down to a few minutes of adapting the example code.

Hi All,

IE 11 in Windows 8.1 (64-bit OS) crashes when calling "Real_getaddrinfoExW()" function, and the module name in event viewer shows "webio.dll". Anyone please help me to overcame this issue.

I would like to know more about Noncopyable Mix-ins and which examples and real-world applications do they work with?

I found this out along with this link:

http://en.wikibooks.org/wiki/More_C%2B%2B_Idioms/Non-copyable_Mixin#Known_Uses

Since that I have several books in C++ in my own pad, not all tutorials are the same.

I have found some information regarding what was in my previous thread.

Can anybody provide me some examples when users try to utilize the Non-copyable mix-ins with the fstream header library?

Maybe someone who can assist me and can provide me some examples regarding this issue.

By the way, I had to clean up some messy code by getting rid of this function - NoImplicitCopy() that is within the link above.  Finally I compiled it, and it worked fine.

Does it protect the entire source code by using the explicit copy constructor only, as well as it protects and assigns mutable parameter types as well?

Should the explicit copy constructor alter the file access configurations in C++ exclusively?

Any feedback as well as some full detailed examples will be fine.

I have altered the following code a bit:

void bar(NoImplicitCopy &n) 
{
 string FileX;
 cout << "Enter the file name you want to protect:   ";
 cin >> FileX;
 ofstream xfOut(FileX);
 xfOut.open(FileX);
 xfOut.close();
}

int main(void)
{
 NoImplicitCopy n;
 NoImplicitCopy x(n);       // Explicit copy.
 bar(n);
 return 0;
}

Although it compiles and runs well, anyone is welcome to make changes to it just to make it better for files exclusively.

I'm having an issue where adding the line:

#include <XInput.h>

is causing an error shown as following:

1>c:\program files (x86)\windows kits\8.1\include\um\winnt.h(147): fatal error C1189: #error :  "No Target Architecture"

I have tried running the same program without that single line and appears to work fine.
Any help or suggestions would be greatly appreciated. I'm only a student learning C++ so simple instructions would be best.

I ran a file recovery program on my sd card and it worked but saved the files in .RES and I can not open it. I am in need of help. The easiest the explanation the better.

Please help!

Hi all, I want to connect remotely to a client desktop, take a screen capture of that desktop, resize the image to fit a specification, and return the image as a bmp for other functions to use.

For taking a screenshot, I am planning to use this.

http://support.microsoft.com/kb/186736/en-gb

But how is C++ going to know the correct desktop to print? What function am I supposed to use for it?

Any comments will be appreciated. Thank you!!!

Hello, I am Hoon-sup, Kim as a beginner for multi-thread.
I would like to use multi-thread MFC code which are consist of three threads(DAQThread, DSPThread, DRAWThread). As you can see in the bottom of this letter, there are three files which are MainFrm1.h, MainFrm1.cpp and ChildView1.cpp. This code can play a role in acquiring CCD camera data and then signal processing of it and last drawing the resultant image of it. When I push the play button, OnDaqOctplaying() function is called and the play button is toggled into stop button and the display shows me real time image at 10 frames per sec correctly.  However, as I want to finish the thread operation, and when I push the stop button which goes into botton part in OnDaqOctplaying(), 126byte size memory leak error occurs because the DRAWThread is terminated forcefully as you can see in the Debug mode Output display. I used global variable such as DAQThreadFlag, DSPThreadFlag and DRAWThreadFlag to finish each thread by itself. However I don't know why the DRAWThread is not finished by itself. I want to know whether it is correct that I am calling RedrawWindow() function in DRAWThread which belongs to CMainFrm class. 

CChildView *pView = (CChildView *)pParam;

pView->RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW);

Is it correct thatI use CChildView *pView when I want to call OnPaint() function of CChildView class in a thread of CMainFrame class?

When I try to finish DRAWThread by itself via global variables, it seems like deadlock and then finally WAIT_TIMEOUT happened.

According to a book about MFC multi-thread, it is said that when we need to access to Main frame window or View window in a specific worker thread under multi-thread, User defined message is recommended to use. For examples,GetActiveView()->PostMessage(....) But there is no any reason why I use User defined message in this situation and I have no any idea about how to implement it in detail.

Please let me know which part or structure of the code that I attached is not correct and do I need toexplicitly write NULL to Handle of DRAWThread right before finishing it?

Thank you very much any way.

I am writing a Visual C++ application, with a member variable CMap<int, int, int, int> m_MyMap;

In the application, there will be two threads, the first one will write to m_MyMap by calling m_MyMap.SetAt, and the second one will lookup the map by calling m_MyMap.Lookup. Is CMap dervied class thread-safe? Or do I need to do anything special to make sure it is thread-safe?

Thanks

In a ribbon, I have the following panel called 'Preset' which contains a gallery (CMFCRibbonGallery)

The default width of the gallery is automaticaly set to 309 pixels. At run time, I can dynamically expand the width of this gallery by using the CMFCRibbonGallery::SetRect(...), so I get the following result:

What should I do now to resize the 'Preset' panel ?

There is no similar function like 'CMFCRibbonPanel::SetRect(...)' for the panel and the RecalcLayout() doesn't fix anything.

Hi,

I have a MFC SDI application developed in VC++ using Visual studio 2013.

Now I want to add plugins like menus,buttons to the existing SDI application.

My intention is that Plugins should add to the existing SDI application without rebuilding the SDI application.

Please guide me with some code samples and links on how I can do it.

Thanks in advance,

Alex

I have to create a list control in my dialog based application and I did that. Now I want to make the list control as, "I will select a row (list) then that will be highlighted and I will right click on the another list to get the popup menu. This time, the first selected list will be lighten the highlighted color and the new one will be highlighted with the dotted lines as showed in the attached image and if I select any action from the popup menu then that should be done for the second selected list".

This image is take from the outlook mail list.

Kindly provide your valuable suggestions

AS im new to this pls send me an sample code

My code was working fine in the previous VS versions, but not in VS 14.

I have a logging in it's own thread. When I unload my dll, the logging thread would write some last notes, but it just stuck in the "_wfopen_s(&logfile, log_file.c_str(), L"a+, ccs=UTF-16LE")" function and never returns.

I have submitted this as a bug report at https://connect.microsoft.com/VisualStudio/Feedback
but I just got a reply to send them the dump file with the Microsoft Visual Studio 2013 Feedback Tool.

The problem with this that I have no dump file since my program stuck and not crashes, and that I can't even install this tool since it's incompatible with VS 14.
