It could be because parallel compilation is used on a multi core machine. If two projects are not strictly dependent, they can be built in parallel.
If you wanted to enforce the build order (including single thread compilation), you could set the dependencies in a single row even though theprojects don't really depend on each other. But why would you want to do this?
The good thing about pessimism is, that you are always either right or pleasently surprised.

If build order is important, then specify project dependencies. That should make the build order exactly the same every time.
If memory serves right, in a multi-project solution, you can right click on a project and set dependencies within the menus there. When you make one project dependent on the others, Studio will build the dependencies first.

I'll guess that you are attempting to access past the end of an array.
code like this,
for(j=1;j<=order;j++)
would normally look like this.
for(j=0;j<order;j++)
as array access is zero based, from 0 to (size - 1)

it compile finely but while running segmentation fault occur and couldnt printf the output.

That issue (indexing past the end of an array) isn't a syntactic issue and won't be flagged by the compiler, it is a logic issue and you will only see a problem at run time.

Do you understand what I said about array access?

The for() loops are wrong.

But you've not shown how it's defined. If you have something like:
float covariance1[5][8];
And you are trying to access it in determinant() like:
for (int p = 1; p <= 5; p++)
covariance1[p][q]...
You can expect an access violation.

Hello everyone!
I need an important information that how much samples VC++ can plot in real-time. I am taking 500 samples per second . Is it possible to plot these samples real time in our VC++ GUI ?
If yes what is the configuration of system that it could support?
If anyone can help me I am really helpful to them.
Thanks in advance.

If you need fast plotting, you're more than likely going to have to get very familiar with the Windows GDI[^]. The toolset is very basic but very fast, works great for high-speed plots.

We would call this a system modal situation, but there is a twist - I have no source code for the application in question (so, no ::SetWindowPos).
The big picture - my application is running, and it's full screen. Think of a kiosk like application... no window manager, no task bar, no keyboard. Should the user choose to, they can invoke a calibration utility for the touchscreen. When calibration is complete, the utility helpfully posts an AfxMessageBox("Calibration complete"). Here's where my woe begins...
If the user is careful, they can press the acknowledge box and the utility terminates. Choose poorly, and the application pops up over the dialog, effectively causing a blocking window inversion.
I think I can work around this by not blocking with the CreateProcess call, but I haven't tried it yet. So, any other ideas? I'm going to write the oem for a variation on the utility, but I don't have much hope there.
thanks

You can still use SetWindowPos.
You just need to get the handle to the message box.
FindWindow will get you this handle.
The best way would be to install a shell hook using SetWindowsHookEx which will then give you a notification when the message box pops up and also its handle.
You could then use SetWindowPos on the handle to make it top most.
It is for you to decide if it is worth installing the shell hook because it will effect the entire system.

You could do your own calibration or have vendor remove dialog box. Failing that, when the calibration utility is started, you could have a thread monitor windows ans when that window pops up, either force it to the foreground or just close it yourself.
Where it gets tricky is that only the current active, foreground application can make another application the foreground and despite appearances, who is this application isn't always straightforward. To get around this for one project, I ended up writing the following (The W is the prefix for my personal, but in-the-public-domain, library:
bool WSetAppToForeground(LPCWSTR pWindowName)
{
HWND hWnd = FindWindow(NULL, pWindowName);
if (!hWnd)
return false;
WSetAppToForeground(hWnd);
return true;
}
void WSetAppToForeground(HWND hWnd, bool showMax, bool setFocus)
{
#ifndef _WIN32_WCE
DWORD foregroundProcessId = GetWindowThreadProcessId(::GetForegroundWindow(), NULL);
DWORD curThreadId = GetCurrentThreadId();
AttachThreadInput(foregroundProcessId, curThreadId, TRUE);
#endif
ShowWindow(hWnd, showMax ? SW_SHOWMAXIMIZED : SW_SHOW);
BringWindowToTop(hWnd);
SetActiveWindow(hWnd);
SetForegroundWindow(hWnd);
if (setFocus)
SetFocus(hWnd);
#ifndef _WIN32_WCE
AttachThreadInput(foregroundProcessId, curThreadId, FALSE);
#endif
}

Hi i am searching many information about this, but i only find complex code. I simply need a context menu with icons. Now i post my code can you help me to complete?
CMenu Menu;
Menu.CreatePopupMenu();
Menu.AppendMenuW(MF_STRING,ID_POPUP_1,(LPCTSTR)_T("Item 1"));
Menu.AppendMenuW(MF_STRING,ID_POPUP_2,(LPCTSTR)_T("Item 2"));
Menu.AppendMenuW(MF_STRING,ID_POPUP_3,(LPCTSTR)_T("Item 3"));
theApp.GetContextMenuManager()->ShowPopupMenu(Menu, point.x, point.y, this, TRUE);
I have seen on MSDN i have to use this:
ASSERT(m_CheckBitmap.LoadBitmap(IDB_CHECKBITMAP));
ASSERT(m_UnCheckBitmap.LoadBitmap(IDB_UNCHECKBITMAP));
CMenu* mmenu = GetMenu();
CMenu* submenu = mmenu->GetSubMenu(4);
ASSERT(submenu->SetMenuItemBitmaps(ID_MENU_BITMAP, MF_BYCOMMAND,
&m_CheckBitmap, &m_UnCheckBitmap));
But i think my situation is more easy than example, but maybe i have problems to merge the two code parts,
please can you help me i don't think take you more time.
Thanks very much.

According to the documentation[^], the bitmaps are just used to indicate the item is selected or not. The MSDN sample shows you how to add the two bitmaps to your menu items. When you say you just want icons, do you mean without any text? If so you need to look at http://msdn.microsoft.com/en-us/library/kb145b0a.aspx[^], for the options to set up individual menu items.

I need a popup menu with an icon 16x16 on the left and the text on the right, for every menu item.

I gave you the link to the documentation, you just need to follow the instructions.
|

|

(disclaimer, I've not tried it on a popup menu; only regular menu).
The simplest way is to use CMFCToolBar::AddToolBarForImageCollection.
You create a dummy toolbar with all the images you want to use and call the above static method and the images will automagically be added to the menus.
I'd rather be phishing!
