Debug Assertion Failed with rgbConverted.cpp - c++-cli

Question

First saying, It's a duplicate question, but not the same problem.
When I run my code, this message is showing, but no error.
#pragma once
using namespace System::Drawing;
ref class rgbConvert

int** getGrayImageArray ()

return GrayArray;
}

}

{

for (int i = 0; i < xsize; i++ )
{
BArray[i] = new bool[ysize];
}
binary = new int * [xsize];
for (int i = 0; i < xsize; i++ )

}

int grayC;
for ( int xVal = 0; xVal < xsize; xVal++ )
{
for( int yVal = 0; yVal < ysize; yVal++ )
{
grayC = GrayArray[xVal][yVal];
if ( grayC >= level )
{
BArray[xVal][yVal] = true;
binary[xVal][yVal] = 1;
fprintf(fp,"%d",binary[xVal][yVal]);
}
else
{
BArray[xVal][yVal] = false;
binary[xVal][yVal] = 0;
fprintf(fp,"%d",binary[xVal][yVal]);
}
}// inner for*/
}
fclose(fp);
return BArray;
}
};
When I press Retry, then breakpoint showing this line.
fprintf(fp,"%d",binary[xVal][yVal]);
If I remove these lines then showing breakpoint in main program.
int main(array<System::String ^> ^args)
{
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Application::Run(gcnew Form1());
return 0;
}
Breakpoint showing in return 0 this line.

Actually this is a well known problem. I have already solved this topics. In my code I had created text files, docx files and images in C drives. But there was no permission for accessing C drive in my computer.
Then I had solved by following this steps:
If you can access cmd, you can reset the security settings in
Vista/Windows 7 with the following command: "secedit /configure /cfg
%windir%\inf\defltbase.inf /db defltbase.sdb /verbose" (no quotes.)
To see what this command does, go here: How do I restore security
settings to the default settings?
NOTE: If you can't access cmd when logged in, use this guide
System Recovery Options. You can get to the command line when you
access the System Recovery Options screen.
This command seems to give the ownership issue a kick up the
backside, even though it seems nothing has changed. Go to Explorer,
right click on C: and go to Properties.
Go to the Security tab and then Advanced.
Go to the Owner tab. Now you should be able to click Edit.
If you don't have Administrators in the list under where it says
"Change owner to:" then go to "Other users or groups". If you do, go
straight to step 7.
On Others users or groups type in "Administrators" (no quotes) in
the bottom box. Click Check Name and then OK.
Click Administrators and then OK. You've now given yourself
ownership of C:! (As long as your account is an Administrator, that
is.)
Click OK on the "Advanced Security Settings..." window to get back
to the Properties window. You should now have a list of the
Permissions and so on where before you only had something about how
you couldn't view permissions. Progress, eh?
You may need to add in the Adminstrators group to edit their
permissions. To do this, click "Edit" and then "Add" and type
"Administrators" (no quotes) in the bottom box. Then hit Check Name
and then OK.
Click Administrators in the list and tick the box in the Allow
column next to "Full control".
Click Apply, you'll likely get a bunch of error messages about how
this can't be applied to some files and folders. Just OK through
them all. Once done, you should have access to your C: drive once
more!
