Hello,

To confirm the behavior of the windows MessageBox API we wrote a simple program and when run on English and French Win7 x64 system the locale of the "OK" button remains to be english and on spanish win7 system it becomes spanish. Please see the attached snapshots for more details.

I would like to understand this difference in behaviour on windows 7 x64 system with Spanish locale.

I will attach the screen shots captured.

I have a Ribbon toolbar added to my VS2012 (C++) project. I would like to use a certain toolbar button as a "state indicator", so that depending on the user's choice or some other conditions it would display different bitmaps (yes, I do not need a button functionality, but am too new to the Ribbon ideology to find a better way for doing so). What I am trying to do is:

1. I have a panel, containing the button A and checkbox B;
2. In CMainFrame::OnCreate() I create and load the CMFCRibbonBar instance.
    Then I either disable (state1), or enable and check (state 2), or enable and uncheck (state 3) the checkbox B - depending on my business logic
    Then I want to set the button A bitmap. To do it, I used code as follows:

    CMFCRibbonBar *pR = GetRibbonBar();
    CMFCButton *pB = (CMFCButton *)pR->FindByID( ID_BUTTON_STATE );
    ASSERT( pB != 0 );
    int btnId = GetBitmapId(); // Pulls the bitmap resource id
    HICON hI = (HICON)::LoadImage( AfxGetInstanceHandle(), 
                                   MAKEINTRESOURCE( btnId ),
                                   IMAGE_BITMAP,
                                   0, 0, LR_LOADTRANSPARENT );
    if( hI != 0 )
        pB->SetImage( hI );

// I also tried direct (initially)
// pR->SetImage( GetImageId() );
// instead, but it did not make any difference

3. On the checkbox B's "clicked" event handler, depending on the state I use the identical piece of code to replace the bitmap according to my logic.

It does not work... The program throws the exception inside

hello dear forum

this above code gives folowing errors when compiling

1>.\receiving.cpp(48) : error C2143: syntax error : missing ';' before '.'

1>.\receiving.cpp(48) : error C2143: syntax error : missing ';' before '.'

how can I proceed ?

thank you 

Hi --

I have some code that I'm trying to integrate with visual Studio inside a Visual Studio package extension.  In order to move this code to an extension package I had to take what was previously just part of a monolithic executable and move it into a separate DLL.  This code bootstraps my custom language engine and generates significant amounts of Intel assembly language code by writing bits to memory.  I eventually jump to an entry point in this generated assembly code and continue execution from there.

When this was all in one executable I had no problems setting breakpoints on and stepping into my generated Assembly language code.  But when I moved it into a separate DLL, although I could step through and set breakpoints on the C++ portion of the code, I ceased to be able to either step into or set breakpoints on the generated assembler language code.  This has nothing to do with it being packaged inside of a Visual Studio extension project, as I was able to demonstrate the same issue with calling my DLL from a very simple console app.

As soon as I moved the code back into a single executable debugging the assembly code started working again.  I really have to get this to work and have no choice but to use a DLL, as the Visual Studio package extension is itself a DLl.

I'm hoping that there is some setting somewhere that I am forgetting about or some simple code fix I can make to get this all to begin working again.  If anyone has any ideas for me, I would be most appreciative.

Thanks.

Hi, I have a few questions regarding the use of HDC in C++.

1) Firstly, its about my title. Is it possible for me to save HDC info into a file, and recreate an image (eg. drawing it on a client rec using HDC) from those HDC info?

2) Assuming its possible in 1, I have tried coding, but nothing gets saved to my file (0 bytes). Where am I going wrong?

struct newBMPinfo
{
	BITMAPINFO info;
	RGBQUAD moreColors[255];
} colors;

void* getScreenCapture(int iXpixel, int iYpixel, int iBMPcolor, int* pSize)
{
	void* cBmpData = NULL;

	if (iBMPcolor != 1 && iBMPcolor != 4 && iBMPcolor != 8 && iBMPcolor != 16 && iBMPcolor != 24 && iBMPcolor != 32)
	{
		printf("Please choose a color system from 1, 4, 8, 16, 24 or 32 bits.");
	}
	else
	{
		HDC hdcScreen;
		HDC hdcMemDC = NULL;
		HBITMAP hbmScreen = NULL;
		BITMAP bmpScreen;
		newBMPinfo bmpinfo;

		double fTempright, fTempbottom, fRatio, fbottomX, fbottomY;
		int itopX, itopY;

		hdcScreen = GetDC(NULL);

		hdcMemDC = CreateCompatibleDC(hdcScreen);

		hbmScreen = CreateCompatibleBitmap(hdcScreen, iXpixel, iYpixel);

		if (hdcMemDC && hbmScreen)
		{
			// Select the compatible bitmap into the compatible memory DC.
			SelectObject(hdcMemDC, hbmScreen);

			SetStretchBltMode(hdcMemDC, HALFTONE);

			//*******************setting new dimensions for scaling****************************
	                              Setting the double and int variables here

                        //Scale my image
			if (StretchBlt(hdcMemDC, itopX, itopY, (int)fbottomX, (int)fbottomY, hdcScreen, 0, 0, GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN), SRCCOPY))
			{
                BITMAP bmpScreen;

                GetObject(hbmScreen, sizeof(BITMAP), &bmpScreen);

                bmpinfo.info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
                bmpinfo.info.bmiHeader.biWidth = bmpScreen.bmWidth;
                bmpinfo.info.bmiHeader.biHeight = bmpScreen.bmHeight;
                bmpinfo.info.bmiHeader.biPlanes = 1;
                bmpinfo.info.bmiHeader.biBitCount = iBMPcolor;
                bmpinfo.info.bmiHeader.biCompression = BI_RGB;
                bmpinfo.info.bmiHeader.biSizeImage = 0;
                bmpinfo.info.bmiHeader.biXPelsPerMeter = 0;
                bmpinfo.info.bmiHeader.biYPelsPerMeter = 0;
                bmpinfo.info.bmiHeader.biClrUsed = 0;
                bmpinfo.info.bmiHeader.biClrImportant = 0;

                DWORD dwBmpSize = ((bmpScreen.bmWidth * bmpinfo.info.bmiHeader.biBitCount + 31) / 32) * 4 * bmpScreen.bmHeight;
                HANDLE hDIB = LocalAlloc(LMEM_FIXED, dwBmpSize);
                cBmpData = (unsigned char*)LocalLock(hDIB);

                // Gets the "bits" from the bitmap and copies them into a buffer
                GetDIBits(hdcScreen, hbmScreen, 0, (UINT)bmpScreen.bmHeight, cBmpData, &bmpinfo.info, DIB_RGB_COLORS);
                // A file is created, this is where we will save the screen capture.
                HANDLE hFile = CreateFile(L"bmpinfo", GENERIC_WRITE, FILE_SHARE_READ, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

                // Add the size of the headers to the size of the bitmap to get the total file size
                DWORD dwSizeofDIB = dwBmpSize + sizeof(BITMAPFILEHEADER) + sizeof(bmpinfo);

                DWORD dwBytesWritten = 0;
                WriteFile(hFile, (LPSTR)cBmpData, dwBmpSize, &dwBytesWritten, NULL);

                //Unlock and Free the DIB from the heap
                LocalUnlock(hDIB);
                LocalFree(hDIB);

				CloseHandle(hFile);
			}
		}

		//delete memory after use
		DeleteObject(hbmScreen);
		DeleteObject(hdcScreen);
		DeleteObject(hdcMemDC);
		ReleaseDC(NULL, hdcScreen);
		ReleaseDC(NULL, hdcMemDC);
	}	

	return cBmpData;
}

3) I have worked out the file reading part. Am I on the right track? How should I go about to display the image on my desktop?

void displayDC(int pSize)
{    DWORD bytesread;
    HANDLE file = CreateFile(L"bmpinfo", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    void* tempData;

    int iFilesize = GetFileSize(file, NULL);

    if (ReadFile(file, &tempData, iFilesize, &bytesread, NULL) == FALSE)
        printf("%d", GetLastError());
}

I am using the guidance of this article to chase down missing header files, and my DebugView window is filled with thousands of the same message:

Info: DCAppConfig -> 'Enable' admin setting is not found. 

I am compiling a C++/MFC project in VS2010. I am trying to determine if this is a message I should be concerned about, and whether it indicates an issue with the settings for our projects.

Hi,

I have put together a simple ATL aggregation example (below).

The inner interface IImplemntation is hosted by CImplementation. The outer interface IImplementation1 is hosted by CImplementation1. The inner IUnknown is created in CImplementation1::FinalConstruct(). The interface Map looks like that:

// Implementation.h : Declaration of the CImplementation

#pragma once
#include "resource.h"       // main symbols
#include "AtlAggregation_i.h"

using namespace ATL;
// CImplementation
// Inner Implementation
class ATL_NO_VTABLE CImplementation :
	public CComObjectRootEx<CComMultiThreadModel>,
	public CComCoClass<CImplementation, &CLSID_Implementation>,
	public IImplementation
{
public:
	CImplementation()
	{
	}

	DECLARE_REGISTRY_RESOURCEID(IDR_IMPLEMENTATION)


	BEGIN_COM_MAP(CImplementation)
		COM_INTERFACE_ENTRY(IImplementation)
	END_COM_MAP()



	DECLARE_PROTECT_FINAL_CONSTRUCT()

	HRESULT FinalConstruct()
	{
		return S_OK;
	}

	void FinalRelease()
	{
	}

public:
	STDMETHOD(Init)(void);
};

// CImplementation1
// Outer Implementation
class ATL_NO_VTABLE CImplementation1 :
	public CComObjectRootEx<CComMultiThreadModel>,
	public CComCoClass<CImplementation1, &CLSID_Implementation>,
	public IImplementation1
{
public:
	CImplementation1() :  m_pInnerUnk(NULL)
	{
	}

      DECLARE_REGISTRY_RESOURCEID(IDR_IMPLEMENTATION)
      DECLARE_PROTECT_FINAL_CONSTRUCT()

         COM_INTERFACE_ENTRY(IImplementation1)
         COM_INTERFACE_ENTRY_AGGREGATE(IID_IImplementation, m_pInnerUnk)
      END_COM_MAP()

	HRESULT FinalConstruct()
	{
		HRESULT hr;
	    hr = CImplementation::_CreatorClass::CreateInstance(
             GetControllingUnknown(), IID_IUnknown,
             (void**)&m_pInnerUnk);
		return hr;
	}

	void FinalRelease()
	{
		m_pInnerUnk->Release();
	}

public:
	STDMETHOD(Init)(void);

	LPUNKNOWN	m_pInnerUnk;
};

In a DLL, a function is exported, and it is defined as:

extern "C" ULONGLONG WINAPI MyFun(CONST LPVOID lpParam);

Now in My app, I need to get the address of the function and invoke it, so I use

typedef ULONGLONG (WINAPI *MyFun) (CONST LPVOID lpParam);

and use

lpMyFun = (MyFun)GetProcAddress(hDLL, "MyFun");

In such a way, there is no way to put the extern "C" modifier in the typedef codeline, I using

extern "C" typedef ULONGLONG (WINAPI *MyFun) (CONST LPVOID lpParam);

but that will cause compiler error.

How to solve the problem?

Thanks

Visual  Studio and Windows knows where each class is put in memory, where each new’ed structure is put, etc. Rather than providing just the address, it would be much more than just nice if the Output window had words to the effect:

By The Way, item X was loaded at that address.

I found this web page:  http://msdn.microsoft.com/en-us/library/x98tx3cf.aspx

And followed that advice.  There was much more information in the output window but the only thing that looked helpful was:

Detected memory leaks!

I did not write wincore.cpp and do not directly call it from my code. That does not help me locate the source of my error.

Further down on the page I find instructions to add this:

#ifdef _DEBUG

  #ifndef DBG_NEW

     #define DBG_NEW new ( _NORMAL_BLOCK , __FILE__ , __LINE__ )

     #definenew DBG_NEW

  #endif

#endif // _DEBUG

With that added the build process complains:

1>Test_ServerDlg.obj : error LNK2005: "void __cdecl operator delete(void *,int,char const *,int)" (??3@YAXPAXHPBDH@Z) already defined in uafxcwd.lib(afxmem.obj)

1>D:\BRYAN\Test_TCP_Thread\Debug\Test_Server.exe : fatal error LNK1169: one or more multiply defined symbols found

Does that mean the delete operator is multiply defined.  I searched my code and it is not defined in anything I wrote.  What might I do to resolve that issue so I can get back to the primary problem?

What can I do to help isolate the problem with my code?

Hello,

I got this code from here: http://msdn.microsoft.com/en-us/library/ms233639(v=vs.100).aspx

Option Explicit

Private Sub Command1_Click()
    Dim frm As COMWinform.COMForm
    Set frm = New COMWinform.COMForm
    frm.ShowForm1
End Sub

Since the article only gives a VB example, I created the whole solution in VB as they explain it.  I also created the VB 6.0 program to call the COM Interop that is being exposed and it works fine.

My problem is I would like to call the COM Interop from a plain "C" 6.0 program(not C#/C++).

Can anybody convert that bit of code to plain ANSI unmanaged C?

Any help would be gratefully appreciated.

Thanks,
Tony

I've been encountering a strange bug in Visual Studio 2012 for some time now. I have a solution consisting of a project which compiles to a static library, and another project which is really simple but depends on this library. After Rebuilding the Solution or just compiling it with 1-3 changed source files, I get the following error:

I don't have a file with the name ,.lib I have tried cleaning the solution, but that doesn't always work.

I am teaching a class of high school students using Visual Studio 2013.  We are learning C++.

When we did a "Hello World!" program and saved it, the files were huge.  I was told there is a setting that allows us to only save the C++ source code.  How do we do that?

I'm using Windows 7 Home Premium and Visual C++ 2010 Express.

Every time I try to create a Visual C++ win32 console application project and then I go into the Win32 Application Wizard, it doesn't show the "current project setting"and I am unable to click "Finish" or "Cancel" there is no next button. 

I am following this tutorial I found and it's supposed to look like this.

This is my first time using Microsoft Visual C++ 2010 Express and I would very much appreciate to find out what I'm doing wrong and if I could have some help on what to do?  Or If I should re install or try Visual Studio 2010

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.

The default "Win32 Console Application" template looks like this:

// SALTEST.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
	return 0;
}

There are no SAL annotations! What would the proper annotations be? I imagine something like:

int _tmain( _In_ int argc, _In_reads_( argc ) _TCHAR* argv[ ] )
{
	return 0;
}

And by extension, what would be the equivalent for a `wchar_t** argv`? There isn't a `_Deref_in_reads( count )`, so I imagine it'd be something like `_Deref_prepost_count_( argc )`?

I think microsoft would see better adoption of SAL if it were included in default templates.

just starting out and wondered if anyone could point me in the right direction?

I have a simple name.txt file on my server containing comma separted names and I want a local C++ app to
check if a name is in the name.txt file?

Also is it possible to write/update to this file from the local app?

The COM Server only takes about 2 MB of space for itself and another 2 MB its space for its data. The server has 2 GB of dedicated RAM and one dedicated processor core. The longest process takes about 12 CPU seconds, this will occur rarely. The short processes take about 1 CPU second. I expect no more than 12 concurrent users. Each process must have its own data. The data is loaded from disk, so I want it to remain resident until the user logs off, or explicitly loads a different data file.

I am guessing the apartment level threading should work fine because it has its own message pump. I am not sure of the best way to handle the data. Currently it is stored in a global std::vector. I am pretty sure that this will be a problem for multiple concurrent processes. The easy solution would seem to be to put the loading of the data and the storage of the data in a single COM callable function. Combined with apartment level threading (which I assume invokes the functions from a FIFO queue) this should keep the data separate for every user because the std::vector data is stored on the system stack.

The problem with this whole scenario is the performance hit of loading from disk every time the 1 second process is invoked. In some cases the data might greatly exceed 2 MB. How can I best handle the data to fully enable multiple concurrent processes and get rid of this performance hit? 

It might even be OK to have multiple copies of the DLL executable loaded (one for each process) since each one takes so little space. Each one of these could have its own global data.
