It looks like you have many arrays of objects, and a destructor is called for EACH array element. It may be possible to delete the whole array with one statement, if your destructor is just freeing memory (as opposed to executing cleanup code).
For example:
D* dArray = (D *) malloc (numberOfDObjects * sizeof (D));
...
delete [] (char *) dArray;
This invokes delete once, rather than numberOfDObjects times. You may be able to use similar logic for arrays of arrays of objects.

malloc and delete do not play well together.
did you meant to use free instead of delete ?
|
|
|
|
|
Oops, my mistrake. You can use free ((char *) dArray), or
D* dArray = (D *) new char [numberOfDObjects * sizeof (D)]; and
delete [] (char *) dArray

Is it surrounded by a bunch of try ... catch blocks? it shouldn't take is much time though. Even in debug mode.

How to get the size of memory pointed by void * pointer?
Thanks in advance!
|
|
|
|
|
Generally there is no way that will work on all conditions. How ever if you are sure that, the pointer will be pointing to a memory allocated using new operator, you can use the _msize function.
|
|
|
|
|
You could use _msize()[^]. For instance,
#include "malloc.h"
...
void* pPointer = new BYTE[100];
int size = _msize( Ptr );
Please note that it won't work if the memory is allocated in stack. Only for memory allocated on heap. Hope it helps.
Regards,
Jijo.

Thank You.
Now how do I write any structure to a xml node?
Any idea?
Thanks in advance!
|
|
|
|

Ah! Now i got the context about what you're trying to do. Export the BITMAP to XML? Bravo! i'd say. 
IMHO, Instead of dumping the BITMAP structure to XML, just get the bitmap data by calling GetBitmapBits()[^] and other necessary information such as width, height, color depth and save that to XML file. Later on by loading these values, you can recreate the bitmap by calling the function - CreateBitmap()[^]. Hope this helps you.
Regards,
Jijo.

I have a BITMAP structure. I need to write it to a xml file.
How do I do this?
|
|
|
|
|
However the hell you want!!?!
Define the structure you'll use to store the info, then fill it - simple.
If you need a prod-along, why not just make the XML file hold ( a subset of) the same info as the BMP file would, in the same order.
E.g for a 5x5 pixel red square, I may use something like:
<BitmapFile>
<FileInfo>
<Width>5</Width>
<Height>5</Height>
<BitPlanes>1</BitPlanes>
<BitsPixel>24</BitPixel>
<CompressionType>0</CompressionType>
<xPixelsMeter>2835</xPixelsMeter>
<yPixelsMeter>2835</yPixelsMeter>
<ColsUsed>0</ColsUsed>
<ColsImportant>0</ColsImportant>
</FileInfo>
<ColorData>
<ScanLine> FF 00 00 FF 00 00 FF 00 00 FF 00 00 FF 00 00 </ScanLine>
<ScanLine> FF 00 00 FF 00 00 FF 00 00 FF 00 00 FF 00 00 </ScanLine>
<ScanLine> FF 00 00 FF 00 00 FF 00 00 FF 00 00 FF 00 00 </ScanLine>
<ScanLine> FF 00 00 FF 00 00 FF 00 00 FF 00 00 FF 00 00 </ScanLine>
<ScanLine> FF 00 00 FF 00 00 FF 00 00 FF 00 00 FF 00 00 </ScanLine>
</ColorData>
<BitmapFile>
One of the many problems with his approach is, that I can't remember if compressed pixels runs are allowed to cross scanLine boundaries (one compressed stream may not end at the end of the scanline it was begun in)
Please excuse me if it's a little forward, but why don't you use ZLib? Instead of busting up all the files for transfer and storing the info into a single large XML file, you could just compress the files together into an archive, and send that. This should provide you with smaller transfers & faster execution since the files are all binary rather than textual representations of the same binary data.

thanks for your suggestions.
Let me give you broader view of what Im trying to do..
Im developing an application that needs to send xml files to a mac system. A similar app on mac should be able to open and interpret the files.
Now the xml file has a header and a data parts.
The Data part will contain multiple node hierarchies as the one that follows:
<item>
<id> 123 </id>
....
....
<note> some notes</note>
<image>
<bitmap>
<height></height>
<width> </width>
...
</bitmap>
</image>
</item>
So I can use zlib on such multipe xml files.
what say..
Please suggest.

I am using the following code to choose the font from font dialog box . now after popup the font dialog box ,I select the font type size color and other properties .Now after clicking the ok button ,I want to display the all information in different comboboxes . my query is how can I get this information out from the font dialog box . I used the following code .
CHOOSEFONT cf; // common dialog box structure
static LOGFONT lf; // logical font structure
static DWORD rgbCurrent; // current text color
HFONT hfont, hfontPrev;
DWORD rgbPrev;
//Initialize CHOOSEFONT
ZeroMemory(&cf, sizeof(CHOOSEFONT));
cf.lStructSize = sizeof (CHOOSEFONT);
cf.hwndOwner = hdWnd;
cf.lpLogFont = &lf;
cf.rgbColors = rgbCurrent;
cf.Flags = CF_SCREENFONTS | CF_EFFECTS;
if (ChooseFont(&cf)==TRUE) {
hfont = CreateFontIndirect(cf.lpLogFont);

What about documentation [^]?

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Still I am not able to get the 1. font size
2.style regular bold and bold italic

Because you didn't read carefully the documentation.
For instance, LOGFONT's lfHeight member looks promising when searching for font size.
lfItalic also maybe useful piece of info and so on...
