Hi,

I have got a code from this forum which create a ellipse on the client area. First it creates a rectangle equivalent to the size of client area. I have put the deflation code in the ::OnTimer( ....) but its not working.

void CTestingCode1View::OnDraw(CDC* pDC)
{
	CTestingCode1Doc* pDoc = GetDocument();
	ASSERT_VALID(pDoc);
	if (!pDoc)
		return;

    GetClientRect(&rect);

    //CRect rc(rect.TopLeft().x+10, rect.TopLeft().y+10,rect.BottomRight().x-10,rect.BottomRight().y-10);


    //CDC *pDC = GetDC();
    CDC WorkDC;
    CBitmap memBmp, * pOldMemBmp;

    WorkDC.CreateCompatibleDC(pDC);
    memBmp.CreateCompatibleBitmap(pDC, rect.Width(), rect.Height());
    pOldMemBmp = (CBitmap *)WorkDC.SelectObject(&memBmp);
	int oldBkMode = WorkDC.SetBkMode(TRANSPARENT);
	WorkDC.Ellipse(rect);
	WorkDC.SetBkMode(oldBkMode);
    // WorkDC.BitBlt(0, 0, rect.Width(), rect.Height(), pDC, 0, 0, SRCCOPY);


     //pDC->BitBlt(0, 0, rect.Width(), rect.Height(), &WorkDC, 0, 0, SRCCOPY);
	pDC->BitBlt(rect.left, rect.top, rect.Width(), rect.Height(), &WorkDC, 0, 0, SRCCOPY);
     WorkDC.SelectObject(pOldMemBmp);
	 pOldMemBmp->DeleteObject();





	// TODO: add draw code for native data here
}
void CTestingCode1View::OnTimer(UINT_PTR nIDEvent)
{
// TODO: Add your message handler code here and/or call default
rect.DeflateRect(10,10);
CView::OnTimer(nIDEvent);
}


int CTestingCode1View::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
SetTimer(1,200,NULL);

i cant seem to get the bolded words to initialize 

Hello Folks:

   Developing on Win8.1 Pro, Visual Studio 2010, C++, WIN32 no MFC.  

   Here is a weird one.  I must be doing something really stupid.  

   I've been adding code to a massive project for years.  It was 100,000 lines of code when I checked a couple of years ago, and is growing.  

   The application's static library has over 200 ".cpp" source files, not counting the headers.  It also relies upon a similar number of source modules from static libraries used by other applications.  

   Yesterday builds started generating this error, formatted to make it easier to understand:

3>tfa.obj : error LNK2019: unresolved external symbol "
         bool __cdecl run_contact_import_from_menu(
                                struct HWND__ *,
                                struct HWND__ *,
                                class PROCESS_RECORD *,
                                class TFA_THREAD_CRYPTO_RECORD *,
                                class TFA_THREAD_CRYPTO_RECORD *,
                                class botan_utilities::EAX_CTR_THREAD_CRYPTO_RECORD *,
                                class TFA_MAIN_WINDOW_CONTEXT *,
                                class std::basic_string<char,
                                      struct std::char_traits<char>,
                                                 class std::allocator<char> > *)"

   I tried a few things.  When I commented out the call to run_contact_import_from_menu() the application built without a problem.  

   I wasn't even working on that part of the application.  

The usual solution:

   I've seen unresolved external symbol errors before of course.  It usually means I've changed the function's arguments without updating the function's forward declaration in a header, and I haven't updated a call to the function elsewhere in the code.  The first thing I did was copy the interface from the function's definition in a "cpp" file:

bool run_contact_import_from_menu(HWND hdlg,
                       HWND change_alert_source_window_handle,
                       PROCESS_RECORD *process_record_ptr,
                       TFA_THREAD_CRYPTO_RECORD *tfa_thread_crypto_ptr,
                       TFA_THREAD_CRYPTO_RECORD *tfa_thread_financial_crypto_ptr,
                       EMAIL_THREAD_CRYPTO_RECORD *tfa_thread_email_crypto_record_ptr,
                       TFA_MAIN_WINDOW_CONTEXT *main_window_dialog_context_ptr,
                                                      std::string *message_string_ptr)

   Same error.  

   EMAIL_THREAD_CRYPTO_RECORD is botan_utilities::EAX_CTR_THREAD_CRYPTO_RECORD:

   From the email thread's header:

      typedef botan_utilities::EAX_CTR_THREAD_CRYPTO_RECORD EMAIL_THREAD_CRYPTO_RECORD;

   For testing, I slapped that typedef in front of the function's forward declaration and the function's definition.  Compiles fine, same link error.  

This seems to be the only unresolved external

   After #ifdef-ing out the call to this function, this application with it's thousands of calls to thousands of different functions built just fine, and ran as expected.  

Is the module's C++ file being processed?

   This function isn't being found in tfa_contact_import.cpp, where it lives.  What happens when I comment out other function definitions in this C++ file?  

   Now I get a whole bunch of "error LNK2019: unresolved external symbol" errors.  Other functions in that file are being referenced, and found.  And missed if they are absent.  

   Is it positional?  run_contact_import_from_menu() is the first function defined in the file.  Moving it to the end of the file gets me the same error.  

   I create a new C++ file with the "Add New Item" to the app's library, just for this function.  Same error.  

   I change the function's name to "run_contact_import_from_menu_x".  New name, same error.  

   I'm missing something really basic, really obvious.  Can someone tell me what it is?  

      Thanks

Hi,

I am testing this simple C++ application below on Windows 2012 R2 and WTSVirtualChannelOpen fails with error code "ERROR_NOT_SUPPORTED". The same application runs fine on Windows Server 2008.

I have tried with WTSVirtualChannelOpenEx but I got the same error code.

Can anyone help me shed some light on this issue? That would be much appreciated :-)

Thank you.

#include <conio.h>
#include <windows.h>
#include <Wtsapi32.h>
#include <iostream>

#define TERMINAL_SERVICES_VC_NAME "TEST"

{
	std::cout << "<< Virtual Channel App >>" << std::endl;
	HANDLE hVirtualChannel = WTSVirtualChannelOpen(WTS_CURRENT_SERVER_HANDLE, WTS_CURRENT_SESSION, TERMINAL_SERVICES_VC_NAME);

	if(hVirtualChannel)
		std::cout << "WTSVirtualChannelOpen successful" << std::endl;
	else
		std::cerr << "WTSVirtualChannelOpen fails with error code: " << GetLastError() << std::endl;

	std::cout << "Press Enter to quit..." << std::endl;

Hi, 

Our team- recently had a problem regarding a lowest level function in x64 bit machines in Windows - and what needs to be preserved in order to safely handle the event and pass it on to Windows Kernel. I am not too experienced in handling functions this deep into Usermode (Ring3). 

Can someone please answer my doubts? 

Thanks

The following code is from an old C++ program that worked under old versions of Windows

int FAR PASCAL _export NewFrameNameDlg(HWND hDlg, unsigned message, WORD wParam, LONG lParam)

but now generates syntax errors as follows

Error1067 error C2061: syntax error : identifier 'NewFrameNameDlg'
Error1068 error C2059: syntax error : ';'
Error1069 error C2059: syntax error : 'type'

Any idea why?

Hi, i have a problem in an application using Windows API CreateProcessAsUser from local system admin in order to run an application as a different user. Everything works fine so far, but the Windows window and frame style are not applied somehow. The window always looks like a Windows 2000 window with huge frames. I also attached some screenshot:

<image missing due to the verify account restrictions>

I also wrote some example code of how we do all the magic in C++ without taking care of handles and stuff.

Just make sure that you have locally some user "test" with password "test" set and try to run the posted source code as local system administrator. Other user will cause an error code 1413 if you try to execute the code.

The problem occurres mainly on Windows 7 VMs in VirtualBox, on some Windows 7 systems and on all Windows 8.1 systems. Very strange. Can anyone help me to solve this problem? Thanks!

This website provides sample code for forced feedback joystick. I wanted to try it with my Logitech Force 3D pro joystick. I used MS Visual studio professional 2013 to run the code, but I am getting errors. Looks like I am missing somethings.

Can someone please help me in running these codes?

i was making this small program with the use of random numbers and when i built it without the console (control+F7) it had succeeded but when i tried to use it with the console (control+F5) the following error below kept appearing, how can i fix this??

i also tried it with this program and the same thing happened

Hi,

I am creating my first Win32 ATL application. I have found that I'm provided with a main window by default. The window has a menu bar on it. I am trying to figure out how to add Active X controls to this window. I can create a new dialog and add controls to the new dialog via the toolbox, but I'm not able to access the main window during design time at all.

Does anyone have any examples of how this is done?

Also, is there a dedicated C++ board for Win32 ATL? I haven't been able to find one on MSDN.

Thanks!

Hi All,

I was do the products migrating from desktop to surface and other tablets that support Windows OS. 

Our product was implemented MFC & ATL, the main product worked as container, then the sub process was launched.

        When try to close the sub-process, it will popup a modal-dialog. If the modal-dialog was issued via surface pen, the application will hang. It works fine if click by hand from touch screen or by mouse clicking.

The main process's UI thread:

I am migrating a C++ DLL from VC 6.0 to Visual Studio 2013.  All tests have passed.

However when I compile for release incorrect results are being returned. 
I have tried numerous compiler settings and finally issolated the one compiler setting that produces a Release version that passes testing.  That setting is /RTCs.  The documentation states that this switch should never be used on retail build.

So, I have added a custom RTC error reporting function by calling _RTC_SetErrorFuncW() during startup.  Next I reran all tests and no RTC errors are reported with either Debug or Release versions of the DLL.

Adding Basic Runtime checks to my release version results in a 25% reduction in speed.

What can be done to find and fix the source of this issue?

Thanks for any suggestions,

Mac

hi everyone

i work with visual C++ 2008 and i'm a project that contains the c and c++ code together.

the project worked correctly but when i add a .cpp and a .h file to the project, the project

errors the c1189 : MFC requires to use winsock2.h

.

look the codes in the .cpp and .h files are correctly because when i add these files to another mfc project will work,

but when add to my project this error will happen.

can you tell me what the problem is?

first part of the my .h file is like below :

___

#pragma once

#ifdef _WINDOWS_
#undef _WINDOWS_
#endif

#include <Afx.h>
#include <afxwin.h>
#include <atlimage.h>
#include <math.h>

___

in addition i need to use the CWnd and CString and CImage ,... Classes in my project, because of this include the afxwin.h(for CWnd) and atlimage.h(for CImage) and ....

so i have to do these, don't i?

remaining part of .h file is :

___

class Object{
public:
    CImage Image;
    short int x,y;
};

class Theme : public CWnd{
private:
    
protected:
    virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support

public:
    CWnd  *Parent;
    CPoint cursor;
    bool drag;
    CString path,imagepath;
    char DialogMove;//0==top to center - 1==center to top - 2==center to down - 3==down to center
    char code,sb;//code = 0=main page - sb=show button=1=ascedung,-1=desceding;
    short int iimage,bstart,bend,//i = index of images-b = index of buttons

    afx_msg void OnLButtonUp(UINT nFlags, CPoint point);
    
    DECLARE_MESSAGE_MAP()
};

after that

in my .cpp file i wrote the body of functions.

so where the problem is?

thanks alot

Hi,

This code returns a strange value! It seems that the CRT function truncates the input strings to their first character.

I get this result: "S V D"

The code compiled as Unicode. Here is the very simple code which show this problem:

.......

#include "stdafx.h"
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
  wchar_t buf[512];
  int len = swprintf_s(buf, 512, L"%s %s %s", L"String", L"Value", L"Data");
  wcout << L"buffer: " << buf << endl;
  return 0;
}
............

This same code runs OK on the vs 2013. The issue seems to be the 'swprintf_s' function which somehow looks at the input strings as chars not wide chars.

Thanks,

G.
