Run-Time Check Failure #2 - Stack around the variable 'NiPlots' was corrupted.

Why do I get this message box pop up in Visual C++.net with the following code when exiting the function:
void CESCView::InitGraphPower(void)
CNiPlots NiPlots;
if (m_NiGraphPower.m_hWnd)
m_NiGraphPower.PlotAreaColor = COLOR_LIGHT_YELLOW;
NiPlots = m_NiGraphPower.GetPlots();
NiPlots.RemoveAll();
NiPlots.Add();
NiPlots.Add();
NiPlots.Add();
NiPlots.Item(VIEW_PLOT_POWER_ACTUAL).SetLineColor(COLOR_BLUE);
NiPlots.Item(VIEW_PLOT_POWER_DCH).SetLineColor(COLOR_RED);
NiPlots.Item(VIEW_PLOT_POWER_REG).SetLineColor(COLOR_RED);
else
ASSERT(FALSE);
The code below runs without any problem
void CESCView::InitGraphPower(void)
//C
NiPlots NiPlots;
if (m_NiGraphPower.m_hWnd)
m_NiGraphPower.PlotAreaColor = COLOR_LIGHT_YELLOW;
//NiPlots = m_NiGraphPower.GetPlots();
m_NiGraphPower.GetPlots().RemoveAll();
m_NiGraphPower.GetPlots().Add();
m_NiGraphPower.GetPlots().Add();
m_NiGraphPower.GetPlots().Add();
m_NiGraphPower.GetPlots().Item(VIEW_PLOT_POWER_ACTUAL).SetLineColor(COLOR_BLUE);
m_NiGraphPower.GetPlots().Item(VIEW_PLOT_POWER_DCH).SetLineColor(COLOR_RED);
m_NiGraphPower.GetPlots().Item(VIEW_PLOT_POWER_REG).SetLineColor(COLOR_RED);
else
ASSERT(FALSE);

Debugging: Run-Time Check Failure #2 - Stack around the variable 'LoggerThread' was corrupted.

I am getting:
Run-Time Check Failure #2 - Stack around the variable 'LoggerThread' was corrupted.
I have searched as much as I can for a description of how to diagnose, but I have not found anything. I don't know how to determine the specific address that is being corrupted. If I knew that, then I could of course set a breakpoint on the condition of that changing.
I have found many answers about other instances of this error, but nothing that descibes how to diagnose this problem. All other problems were simple enough that the problem could be determined by looking at the code. I have looked at my code extensively and I don't see a problem. One of the previous answers I have found is Error: Stack corruption around the variable 'tm' but the current version of the program uses only default alignment.
This particular problem is a symptom of a problem that has had various other symptoms, most of which would be more difficult to diagnose. Therefore the problem is probably more subtle than most. I initially encountered the problem in a DLL project, but I wrote a console program to use and test the relevant code. It is the console version that I am debugging.

Hey, these data breakpoints are really not that hard to use ;-)
Actually they are useless for me when I use my own system, which is only 350 MHz. On that system, even very simple programs run noticeably slow and any meaningful debugging is impossible. The problem I am encountering I am developing and debugging using a fast system, so the performance is not likely to be a probem, but that has been a problem for me in the past.
You probably haven't set the breakpoints in the correct way (again you should calculate the address yourself and leave the context empty so that the hardware debug breakpoint registers can be used).
Sam Hobbs wrote:
One of us does not understand. First, I must correct what I said before; the stack is used in reverse of what I was thinking. I knew that but I forgot. In other words, for each item local appearing in a function, the addresses decrease. The processor's stack pointer register is decreased for each item put into it, which makes sense, because then the processor knows there is a problem when the register gets to zero or less.
Yes, I certainly understand that the error message is referring to memory before and after LoggerThread.
There is an important difference between stack memory before a function's allocations and after.
So for example if we have:
Code Snippet
void Level3(int a) {
char Local[4];
std::cout << "In Level3 Local is at " << &Local << '\n';
void Level2(int a) {
char Local[4];
std::cout << "In Level2 Local is at " << &Local << '\n';
Level3(3);
void Level1(int a) {
char Local[4];
std::cout << "In Level1 Local is at " << &Local << '\n';
Level2(2);
int main(int argc, char* argv[]) {
(void)argc, argv;
char Local[4]="321";
unsigned *pStack;
_asm {mov pStack, esp}
std::cout << "The stack is at " << pStack << '\n';
std::cout << "In main Local is at " << &Local << '\n';
Level1(1);
return 0;
Then the ouput I get is:
The stack is at 0012FF1C
In main Local is at 0012FF6C
In Level1 Local is at 0012FF0C
In Level2 Local is at 0012FEB0
In Level3 Local is at 0012FE54
Note that the addresses decrease. If I create a breakpoint using "{main,,} *(Local-256)" for 256 elements, then that breakpoint breaks constantly due to normal use of the stack. That makes debugging more difficult; are you aware of that problem?
Unsurprisingly the debugger will watch for modifications of 256 bytes if you tell it to do so. But I don't see why you would want to do it? It is obvious that this extends into callee stack space. There are only two bytes that you should be interested in: the one before the clobbered local and the one after. Of course, during its lifetime its allocated address will never change. And in debug stack frames its memory location is never shared with any other code. Any modification to it indicates a programming error.
Also, do note that scoped data breakpoints have had some performance problems. Again, if you care about performance calculate the address manually and set a data breakpoint without a C++ scope and make sure you don't exceed the number of available hardware watchpoint registers (IIRC there are 4 HW breakpoint registers which can watch 1,2 or 4 bytes at a given (aligned?) address). With HW watchpoints you shouldn't see any performance degradation.

Run-Time Check Failure #2 - Stack around the variable was corrupted.

I had checked on net as well as on social msdn site for this kind of error. Usually error is due to writing out of index. I tried to figure out same mistake in below mentioned code but I failed to do so. I am using Visual Studio 2010 for compilation
on Windows 7 (64 bit) machine. I am getting following error "Run-Time Check Failure #2 - Stack around the variable 'lcPacketPrefix' was corrupted."
#include <stdio.h>
#include <stdlib.h>

Little guidance will be helpful.

As it is in your code.
strcpy_s(lcPacketPrefix+(sizeof(lcPacketPrefix)-strlen(lcPacketLen)),sizeof(lcPacketPrefix),lcPacketLen);
You're saying that the size of the buffer is greater than it is
because you're offsetting the start pointer.
If you'd more correctly written the code like this:
size_t offset = (sizeof(lcPacketPrefix) - strlen(lcPacketLen));
strcpy_s(lcPacketPrefix+offset,sizeof(lcPacketPrefix)-offset,lcPacketLen);
You'd have got a run-time error in the debug version of your code.
However that's not what you want. Try something like this instead:
size_t offset = (sizeof(lcPacketPrefix) - strlen(lcPacketLen));
strncpy(lcPacketPrefix + offset, lcPacketLen, strlen(lcPacketLen) );
But most importantly, understand what you'd done wrong and learn from
it.

Error run-time 429 ActiveX can't create the object Financial Reporting

Hi everybody,
I'm trying to run Financial Reporting 9.3.1 on my pc with Winodws Vista but as I launch the exe it shows me an error message:
Error run-time 429 ActiveX can't create the object
I know it works out with XP. Is there a problem with Vista? How can I fix it?
Thanks in advance

I cannot say this IS your problem, but some oddities I ran into installing the report client on my laptop in my current environment ....
#1 - Even though you type in your username and password in the Reports login box, it apparently uses the credentials of the logged on user.
#2 - The machine MUST be on the domain that is used for authentication or it flat out won't work (see item #1)
#3 - I ran into the ActiveX error once and apparently something did not register properly during the install. To fix it :
Run the batch file : %HYPERION_HOME%\BIPlus\install\bin\HRRunAnt.cmd
Where %HYPERION_HOME% is the main hyperion folder. (i.e. c:\hyperion )
After the script executes, reboot your machine. You MUST reboot.
Hope that helps.

I have 3 downloads from yesterday that I receive this error code. Any ideas?
Thank you!

I may have stumbled upon something that could help. A type of "detour" around the problem.
I just started experiencing this problem a few days ago. Anytime I'd try to download a song/video/movie, I would get the message, "Unable to check for available downloads. The network connection was reset".
So, instead of selecting "Check for Available Downloads" under "Advanced" menu...
I logged into "My Account" page in itunes. If there are available downloads it comes up at the top of the page with the option button "Download Now". When I select that -- it downloads immediately.
Can't promise it will work every time. But it's worked for me so far. Good luck...

My computer has been spontaneously restarting itself. This last time I wasn't even at the keyboard, I was across the room. I don't know what to make of it, completely baffled.

Using a checkbox in numbers- if,then, I want to display today's date if checked, and keep that date, the day it was checked, not the current day

this will not work. Numbers does not provide a timestamp. you can, however, enter the formula "=now()" in any cell, then copy that same cell, then paste (using the command "Edit > Paste Formula Results"
If you need a time stamp often,
make a single cell table with the formula (mentioned earlier).
and copy and paste as needed

Unable to check for available downloads. The network connecting was lost.

I have purchased a film on my Apple TV and now want to download it to my iTunes on my MacBook. I can see that I have 1 available download, but when i try to down load it, it just keeps saying:
"Unable to check for available downloads. The networl connection was lost"
I know there is not a problem if my network!
is anyone else having the same problem? Is this a problem with iTunes or my MacBook?
cheers

If I choose a hard drive ask my backup disk for time machine, will it clear out the data that was previously stored in my hard drive?

Hello edjhsu,
Unless the drive is in a format that isn't compatible with Time Machine, the files will not be overrwitten. However it is typically a better idea to keep your files and your backup separate, especially since files on the Time Machine drive will not be backed up by Time Machine.

Error in Apple Configurator - Unable to Download iOS 7.1.2. The firmware image was corrupted.

The initial update of some iPads failed while preparing them in Apple Configurator. Now this message, Unable to Download iOS 7.1.2. The firmware image was corrupted, appears every time I try to prepare using the Configurator. Can the corrupted firmware image be deleted or is there away around the error?

It should be located here:
~/Library/Containers/com.apple.configurator/Data/Library/Caches/com.apple.config urator/Firmware/
Try deleting the ipsw from here and re-download it.

HT201210 I am stuck with "The iPad could not be restored because the firmware file was corrupt" message.

Hi
I have an iPad mini and it was on iOS 6.1.3, my friend came and he said that he knows how to install iOS 7 for me. I gave it to him and he tried to install it, but apparently he failed to do so and an "Activation Error" is appearing on the screen now asking me to register in the developers program.
Now, we are trying to restore it back to iOS 6.1.3 using iTunes, the software downloads well and it starts restoring but that I keep getting this error message "The iPad could not be restored because the firmware file was corrupt.".
I am sure that the file is not corrupted because it's downloaded via iTunes regular download and it's not from an outside source.
I am stuck with this now and my iPad is useless this way.
Please any suggestions ?

Yes, don't download Beta Software that you have no business or legal right to download and quit taking bad advice from friends.
Now to maybe get you out of the restoring jam, the only thing that I can think of that might work is to use recovery mode, unless you already tried it and it didn't work.
You can read about it here, but the instructions are posted below.
http://support.apple.com/kb/ht4097
Disconnect the USB cable from the iPad, but leave the other end of the cable connected to your computer's USB port.
Turn off iPad: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for iPad to turn off.
If you cannot turn off iPad using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the iPad turns off, release the Sleep/Wake and Home buttons.
While pressing and holding the Home button, reconnect the USB cable to iPad. When you reconnect the USB cable, iPad should power on.
Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears you can release the Home button.
If necessary, open iTunes. You should see the recovery mode alert that iTunes has detected an iPad in recovery mode.
Use iTunes to restore iPad.
