Thread: Problem with file IO

Sorry, one last thing, there is nothing between #include ".\fswinview.h" and #ifdef _DEBUG. I added the ... by mistake.

It now looks like this:

Code:

// FSWinView.cpp : implementation of the CFSWinView class
//
#include "stdafx.h"
#include "FSWin.h"
///////////////////////
//// TEST // TEST /////
#include <iostream> ///
#include <fstream>  ///
using namespace std;///
//// TEST // TEST /////
///////////////////////
#include "camera.h"
#include "FSWinDoc.h"
...

That fixed the compiling, awesome! I didn't need to remove the #include "stdafx.h" or turn off precompiled headers. Thanks CornedBee. But I still get the assertion error during debugging. The problem is caused by something in this section:

Code:

// Display contents of "sa" (array of Kelvin temperature values) in the CString object "table".
	float HUGEP *a_image;
	sa.AccessData((void HUGEP **)&a_image);
	for (int x=0 ; x<10 ; x++) // x<10 should be x<w
	{
		for (int y=0 ; y<10 ; y++) // y<10 should be y<h
		{
			s.Format("%4.2f  ", a_image[w*x+y]);
			table += s;
		}
		s.Format(_T("\n"));
		table += s;
	}

Any ideas?

"sa" is defined earlier as a COleSafeArray object. It can be seen in the code I posted on page 2 of this thread, and below. Note: "va" is an array of floating point values.

Code:

COleSafeArray sa;
	sa.Attach(va);

I'm pretty sure my loop limits are correct. While I was testing with AfxMessageBox, I set the loops to only display a portion of the array. I added those comments so that I would remember to eventually change them back. Below shows how w and h are defined. When executed, w= 320 and h=240.

Code:

long w, h;
	... ... ...
	sa.GetUBound(1, &w);
	sa.GetUBound(2, &h);
	w++;
	h++;

The exact error message I get is:

Microsoft Visual C++ Debug Library

Debug Assertion Failed!

Program: ...tor\My Documents\Working Copies\Copy of FSWin\Debug\FSWin.exe

For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts.

(Press Retry to debug the application)

If the debugger tells me more, I don't know where to find it.

I'm a huge dope. I fixed it. I was using the COleSafeArray member "AccessData" without subsequently using "UnaccessData". Once I added that to my code, I was no longer getting the failed assertion.

Thanks for all your help!
Kind regards,
