I am working on a C++ Win32 console application. Whenever I close the Visual Studio 2013 with the application open, I get the following error:

"An error occurred while creating or opening the C++ browsing database file C:\Users\[user]\Documents\Visual Studio 2013\Projects\StartingOutwCpp\StartingOutwCpp.sdf. IntelliSence and browsing information will not be available for C++ projects.

Ensure that Microsoft SQL Server Compact 4.0 is installed and that no other applications are accessing the file. If this problem persists, delete the file and reopen the solution."

And sure enough, the Intelisense is also not working, and the VS is running painfully slow as well. I made sure that Microsoft SQL Server Compact 4.0 is installed and that no other applications are accessing the file. I've deleted the file, still getting the error. I have also repaired and even re-installed VS, and tried creating a new project and moving the files from the old project over. Same error.

Note: This error is not generated when editing C# applications, only C++

I've created dozens of C++ COM Add-Ins using Visual Studio 2010. However, 2013 will not let me get passed the following step.  When I  right click in the Class View and select "Implement Interface ..."  the following occurs:

1.  First the Wizard shows up.   I select "Microsoft Add-In Designer<1.0>"

2.  After selecting _IDTExtensibility2 interface I select Finish and get the following error
"An error occurred while setting the error info."

When I create a CMFCSpinButtonCtrl object with the UDS_HORZ style, the scroll arrows remain in the vertical orientation (using VS 2013). For example:

CMFCSpinButtonCtrl m_wndSpin;  //declared in header file

m_WndSpin->Create(WS_CHILD | WS_VISIBLE | UDS_ARROWKEYS | UDS_SETBUDDYINT | UDS_HORZ, rectSpin, this, ID_SPIN);

With this line of code in my OnInitialUpdate of my CView-derived class, the scroll button appears with the arrows in the up-down orientation, even though the UDS_HORZ should make them horizontal. When I use the CSpinButtonCtrl (non-MFC version), the arrow are correct.

Is there a work-around or fix for this bug?

Hi,

I run on two computers (one is Windows 7 64 bit, the other is a vm windows 10) this version of visual studio. Consistently the clang tools are NOT installed.

I DID select everything when the installation started, it just does NOT do it.

Anyone seen this?

Thanks,

Hi,

I'm new to Visual C++ and I have to modify an existing DLL built in VC++ 6.0.

It is using access 97 as its back end. I need to modify this to work with Access 2010.

I know that I have to add reference to acedao dll instead of dbdao.

Could anyone tell me the process for adding reference in Visual C++ 6.0?

Thanks

Hi,

There is a requirement to make container having 2-3 tabs and each tab corresponds to separate executable. So i need to embed these exe in each corresponding tab so that only one container UI can show other executables UI by clicking on each tab.

Which redistributable package should be installed at the client side for binaries built with either Visual C++ 2013 Update 3 or 4? 

From the Download Center, "Visual C++ Redistributable Packages for Visual Studio 2013",http://www.microsoft.com/en-us/download/details.aspx?id=40784 I downloaded "vcredist_x86.exe" and "vcredist_x64.exe", which have version number 12.0.21005.1

My system, which has installed VS2013 Update 3, also has "vcredist_x86.exe" and "vcredist_x64.exe", at "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\redist\1033", but these having a higher version number: 12.0.30501.0

A colleague of mine has installed  VS2013 Update 4, but has the same redistributable files as my VS2013 Update 3 installation: version 12.0.30501.0.

Is it correct to conclude that

1. the VS2013 redistributables at Microsoft's Download Center (12.0.21005.1) are outdated?
2. VS2013 Update 3 and Update 4 based applications may share the very same redistributable package (12.0.30501.0)?

I have my CListCtrlEx derived from CListCtrl. This list have style LVS_REPORT, LVS_OWNERDRAWFIXED and LVS_EX_GRIDLINES. I have added possibility to change font for this list. This works fine, but there is one bad thing - if I change font and before that I have not been scrolling list, then all list items redraws right, but if I have done scrolling before font changing, then list items redraws a little bit upper or lower than list grid horizontal lines, i. e. items text becomes overlapped by grid lines.

Here is how I changing list font:

LRESULT CListCtrlEx::OnSetFont(WPARAM wParam, LPARAM)
{
   LRESULT res = Default();

   CRect rc;
   GetWindowRect(&rc);

   WINDOWPOS wp;
   wp.hwnd  = m_hWnd;
   wp.cx    = rc.Width();
   wp.cy    = rc.Height();
   wp.flags = SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOOWNERZORDER | SWP_NOZORDER;
   SendMessage(WM_WINDOWPOSCHANGED, 0, (LPARAM)&wp);

   return res;
}

void CListCtrlEx::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
   HDC hDC = ::GetDC(NULL);
   CFont* pFont = GetFont();
   HFONT hFontOld = (HFONT)SelectObject(hDC, pFont->GetSafeHandle());
   CRect rect;

   DrawText(hDC, _T(" "), 1, rect, DT_SINGLELINE | DT_CALCRECT);
   lpMeasureItemStruct->itemHeight = rect.bottom - rect.top;
   SelectObject(hDC, hFontOld);
   ::ReleaseDC(NULL, hDC);
}

After doing CreatePolygonRgn and SelectClipRgn, I draw a vector long enough to cover the polygon area --- pDC->MoveTo(p1) & LineTo(p2).

The p1 & p2 are adjusted each time based on the current zoom factor of the screen. As I zoom in using the mouse wheel, at some point, a piece of the line is broken and displaced on a wrong spot... That is, I see two lines.  This happens at some high zoom factor, and if I zoom out again, my line is OK with the proper clipping based on my polygon.  

This only happens on lines close to vertical (but not exactly 90 degrees), and only on some high zoom-in situation. As I pan the picture, the broken line lengths change.

I am re-drawing the line every time I zoom or pan, executing the same piece of code that sets the clip rgn, draw, and disable the clip by pDC->SelectClipRgn().

Is this a graphic card issue?  This problem does not happen in PC SAFE MODE run...

Thank you 
Makoto

Hi, a few of us are trying to compile Google's protobuf library, and are having an unresolved inline function issue with the new VS 2015 community RC. The issue is described  at Protobuf's github page: https://github.com/google/protobuf/issues/240. Note that the compile error only occurs in release mode.

Thanks

I have converted a Visual Studio 2010 solution to Visual Studio 2012. Platform Toolset for all projects in the solution is automatically updated to Visual Studio 2012. Then I got “error C2248: 'CObject::CObject' : cannot access private member declared in class 'CObject'” from a CLR enabled project. The error was caused by a AFX_CLASS_EXPORT class:

class AFX_CLASS_EXPORT CMyList : public CList<int*, int*&>
{
...
}

I changed Platform Toolset for this project to Visual Studio 2010 and the project and solution built without problem.

Why do I have to use Visual Studio 2010 toolset to build this project? Isn’t this a problem for a develop environment without Visual Studio 2010?

I appreciate any advice and suggestion.

Hi.

I found that almost Visual Studio 2013 application has compatibility problem.

* environment

Windows 7 SP1

1. compile MFC application
2. set Windows 2000 compatibility mode.
3. execute it.
4. always they crash.

Windows 8.1

1. compile MFC application
2. set Windows XP compatibility mode.
3. edit with registry "HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers". change "WINXPSP3" to "WIN2000"
4. execute it.
5. always they crash.

The 2015 RC is NICE!

I have an all template file that uses complex<T>, vector<complex<T>> and some complex<T>*  to get rid of a level of indirect  access though vector<> that has various FFT implementations including spinning off threads for many of the severable functions. It works great and I've been pretty happy with the code optimization these days. I even coded direct complex operations to try to improve cache misses and generate faster performance with no improvement at all.

Running the code through the 2013 PGO reduced the full static build exe size about 10% but the 2013 version execution time was unchanged. However, running the 2015 RC PGO not only reduced the exe size but improved performance a surprising (to me) 15%.  In looking at the dissasm, the critical sections were significantly reduced with excellent use of the extended instruction set. The inner loop was shortened from 380 to about 270 bytes in length with rather lovely looking, extended instruction set code. It was a redo by the PGO since the code before the PGO was virtually identical.

I have a question about PogoSafeMose, an environment variable that determines whether the probes inserted into the program are thread safe or not.

Interestingly, the results were the same with and without setting the PogoSafeMode environment because I was using threads. Also the time taken to execute the training was the same. This was the case on both platforms. This was running the PGO through the VS menus so I wonder if they default to PogoSafeMode.

It seems the flickering is generated by the CombineRgn function, but I really have no idea why this happens, since i've never used regions that much I'm possibly missing some knowledge on the matter.

Some events in the program triggers the addition of little rectangles to the main region, here's the code that handles that:

                        HRGN ActualRegion = CreateRectRgn(0, 0, 0, 0);
			GetWindowRgn(hwnd, ActualRegion);
			HRGN AddedRect = CreateRectRgn(//long code that creates a rectangle)
			CombineRgn(ActualRegion, ActualRegion, AddedRect, RGN_OR);

			SetWindowRgn(hwnd, ActualRegion, FALSE);
			InvalidateRect(hwnd, NULL, FALSE);

White Flickering appears only after the invalidation if new regions where combined to the main one.


Here's how I'm implementing double buffering in WM_PAINT:
PLEASE NOTE that on creation i'm enabling the DWM blur behind function with an invalid region (different from the Main one) which means that everything painted with BLACK_BRUSH will result in a 100% "invisible" portion of the program

                RECT r;	GetClientRect(hwnd, &r);

		PAINTSTRUCT ps; HDC hdc = BeginPaint(hwnd, &ps);
		HDC MemDc = CreateCompatibleDC(hdc);
		HBITMAP hBmp = CreateCompatibleBitmap(hdc, r.right, r.bottom);
		HBITMAP hOld = (HBITMAP)SelectObject(MemDc, hBmp);

		//Making sure this dc is filled with "invisible" pixels to display
		SelectObject(MemDc, GetStockObject(BLACK_BRUSH));
		Rectangle(MemDc, //arbitrary values that matches the entire screen);

		BitBlt(hdc, 0, 0, GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN), MemDc, 0, 0, 		SRCCOPY);

		//clean-up
		SelectObject(MemDc, hOld);
		DeleteObject(hBmp);
		DeleteDC(MemDc);
		EndPaint(hwnd, &ps);

WM_ERASEBKGND obviously returns TRUE without further handling, the WNDCLASSEX instance of the window has a default BLACK_BRUSH as the hbrBackground field.

I also tried to intercept and return TRUE from WM_NCPAINT message.

I'm doing everything necessary to avoid intermediate drawcalls, everything handled inside the WM_PAINT uses a backbuffer, also i'd like to mention i'm not working with images/bitmaps. Everything is drawn with gdi/gdi+, and in no place i'm actually issuing a "white" redraw that may possibly cause said flicker. I'm a bit lost here

Is it something that i'm possibly missing ? I can't really understand what may be causing white flickering in this scenario

We are opening executable using ShellExecuteEx API. This executable runs in background and should not prompt for credentials(login,pwd).

SHELLEXECUTEINFO sei;
// Make sure to initialize all memory to zero.
ZeroMemory(&sei,sizeof(sei));

sei.cbSize = sizeof(sei);
//sei.fMask = SEE_MASK_NOCLOSEPROCESS; 
sei.hwnd = pWindow? pWindow->m_hWnd : NULL;
//if (SHELL_EXECUTE_VERB_MUST_NOT_USE == verb)
{
sei.lpVerb = NULL;
}
/*else
{
sei.lpVerb = L"open";
}*/
sei.lpFile = appOrDocument;

//if (EMPTY_STRING != appCmdLineParameter)
if(0 != _wcsicmp(appCmdLineParameter,EMPTY_STRING))
{
sei.lpParameters =  appCmdLineParameter;//this contains path of the executable and arguments
}
else
{
sei.lpParameters = NULL;
}
//sei.nShow = SW_SHOWNORMAL;
sei.hwnd = SW_HIDE;
sei.nShow = SW_HIDE;

ShellExecuteEx(&sei, dwErr);  

Is there any way to call executable by different credentials than windows login when we know only login name and not pwd.

Sometimes it works, more often it does not. When it fails, 3.9GB are in use and 11.5GB are available. Anyone got any pointers as to what is going on? Any help appreciated.
