c1xx : fatal error C1060: compiler is out of heap space

This error comes up four times, with four diffrent files. As far as I can see, this has something to do with #includes.

Hm... did you actually set a high swap file size?
according to the docs, a *high* /Zm makes sense
Does it get better with moving headers to/from stdafx.h?

Well, win xp pro is telling me that total size of all paging files is 3068 MB, so I'm assuming that it's not a problem. Windows manages the size of those files and I got *plenty* of disk space, so I think I should be covered there...;P

I tried to move the file tables.h (with the array) to stdafx.h, but seemingly to help. stdafx.cpp compiled, after a long while, without reporting any problems, but all the other source files reported the same error. Cry | :((

You do declare the array as "extern CString yadda[][][], do you?

Can you, just for a test, reduce the CString array to [1][1][1], or even better, declare as

typedef CString[b][c] CStringMatrix;
extern CStringMatrix * array;

and instantiate it as

CStringMatrix * array = new CStringMatrix[a];

this should change nothing syntactically when using accessing the array, but moves it to the heap.

Just to see if the array is really the culprit

Actually, being the newbie that I am, I didn't use extern, but it doesn't seem to make a diffrence in itself.

I tried to experiment with which number I could use with /Zm. I get "out of heap space" at about 128, while setting the value to default, 127, gives "fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit".

I tried to use extern CString yadda[1][1][1], which worked out quite OK, actually, as long as I didn't exceed 127... Smile | :)

Now, It seems the real question is: isn't a little below 3GB large enough swap file? WTF | :WTF:

But it definitely does (maybe not for your problem, but in terms of C++)

if you use

int x;

in a header file, every .cpp that includes it gets it's own instance of x. To get a "truly global" x, you need to declare

extern int x;

in the header file, and

int x = 0;

(or any other initializer value) in one .cpp file.

On the main topic, I'm out of ideas. might be this *is* a problem with the compiler. The only option that I see is moving the array to the heap, as described earlier. Sorry.

Hmmm... seems like I have found a solution. The compiler gives more room for change in /Zm when I clean the temp files before rebuilding after changing the number. In other words, I changed the /Zm number to 900, and chose clean on the build menu before building. That worked, but gives me two questions I am curious about. Why do I need to clean first to get a effect? Why does the number need to be som much bigger on VStudio.net vs. VS 6.0?

Can you somehow answer this?

Have you tried to dynamically allocate the array on the heap using the new operator? It may be a better solution. You may even want to wrap it in a class to manage computing the offsets into a linear array from your x, y, z coordinates...

Just allocate the array as linear:
CString *m_pScores;

m_pScores = new CString(18*12*50);

then when accessing them, compute the offset

CString GetScore(int iX, int iY, int iZ)
{
return *(m_pScores[iX * iY * iZ]);
}

void SetScore(int iX, int iY, int iZ, CString cScore)
{
*(m_pScores[iX * iY * iZ]) = cScore;
}

onwards and upwards...

First off, maybe a dumb question: If you simply multiply x, y, and z coordinates, how can you be sure that you don't have multiple combinations which gives the same result. Won't this be a problem Confused | :confused:

Second, it's a reason for my setup. I have 18 written pages, with a table on each which I had to get into a computer. Done. The tables had 12 coloumns each, and each coloumn had 50 diffrent values. I pretty much need a solution that easy to insert those data. It might just be me, but 10800 * SetScore don't seem to me to be the best way to go...?

I was looking for a better way to create those tables, so I appreciate that, but I need to do it without creating source-code-hell Big Grin | :-D

Colour saturation in GDI+

19-Jun-03 0:05

When you use the ImageAttributes class to set the colour transformation matrix to draw an image, the only the fractional part of the resulting colour values are retained, so that the values don't go above 1.0.

Is there any way of instructing GDI+ to saturate the colour values intead (ie. if they're above 1.0, then set them to 1.0)? I can't find anything in the docs, but perhaps someone has already had to deal with this before...

Thanks

Strange Compiler Error ....

I have a strange compiler error on my program. My compiler is Visual C++ .Net. The error is:
"error C2872: 'IServiceProvider' : ambiguous symbol"
on the file afxole.h of the MFC.
I don't understand what is the problem, because I don't use that class ...
Can you help me ?
Thank you very much for any answer.

Are you programming a COM component? If so, have you initialized COM? in case of ambiguous symbol ... search msdn for C2872 and you'll get the following.

'symbol' : ambiguous symbol<br />
<br />
The compiler cannot determine which symbol you are referring to.<br />
<br />
The following sample generates C2872:<br />
<br />
// C2872.cpp<br />
namespace A<br />
{<br />
   int i;<br />
}<br />
<br />
using namespace A;<br />
int i;<br />
void z()<br />
{<br />
   ::i++;   // ok<br />
   A::i++;   // ok<br />
   i++;   // C2872, ::i or A::i?<br />
}<br />

I would use MCI. Send these 3 MCI strings:

open CDaudio alias cd sharable wait
set cd door locked wait
close cd wait

This should lock the standard CD-ROM drive.

Try Floplock.exe a M$ prog, from the SDK with source code, it locks floppy and COM port, so might give you an idea. If you can't find the source I can email it to you 1 .C file 25K

CreateFont creates font of different weight if escapement is non zero.

I'm rotating text using escapement parameter in CFont::CreateFont(). Text is geting rotated correctly, but for Arial font, it becomes Bold when it is rotated by either of 90, 180 or 270 degrees.
Do I need to do any thing more for making normal and rotated text look alike?
Here's the code-

font.CreateFont(m_propbyFontSize * 1.5 * 20, 0, nRotationAngle * 10, 0, nFontWeight, bIsItalic, bIsUnderline, bIsStrikeout, ANSI_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH | FF_SWISS, m_propstrFontName);

This is important for me to fix ASAP.

Thanks in advance.

It doesn't change weight. If you print this on paper, you'll find that there is very little difference. There are two reasons. One is that the resolution of a screen is not particularly good. The other is that GDI can not rotate text very well. If it has to look better, try using GDI+, which does a far better job.

Hope this helps

Thanks for your valuable inputs. Now-
What needs to be done to do the same using GDI+. I need this to work on Windows 2k properly.
What's the minimum changes Can I do in my existing code to get support of GDI+?

Few things that are happening are-
The problem in only with certain fonts.
Arial is one of the font that is showing this problem.
Times New Roman is working fine.
Print preview as well as prints seem to be same for both Normal and Rotated texts.

You need to include "gdiplus.h" and link to the library, call GdiplusStartup() before you use GDI+ and call GdiplusShutdown() when you finish. You can create a graphics context from a GDI HDC by using Graphics g(hDC) (or Graphics g(dc.GetSafeHdc()) if you're using MFC). After that, you can start drawing in GDI+ however you like.

Look at one of the tutorials to get you started.

Power of 2?

Hello,

whats the fastest formula/algorithm to determine if a number is a power of 2?

It's easy to check this in a while loop shifting the number 1 to the right and checking if it is 1, but perhaps there is a faster method?
