Hi
I want to change the "if and else" statement of the following code in to a different fashion,(not with if and else ladder)
what i want to achieve with the code is: Any one of the pointers (p1,p2,p3) will be non NULL...at any given time. (For the time being I am hard-coding with the address of value i, but in actual I may be passing the i value to the function) Others will be NULL for sure...i need to check which is not NULL...that's it
Note: I would be using dynamic_cast, to assign the i value later..... [dynamic_cast returns 0, if cast was not happened ]
int i=10;
int *p1=NULL;
int *p2=&i;
int *p3=NULL;
if(p1!=NULL)
{
printf("\n\np1");
}
else if(p2!=NULL)
{
printf("\n\np2");
}
else if(p3!=NULL)
{
printf("\n\np3");
}
else
{
printf("\n\nnone");
}
thanks in advance

The else without the associated condition handles the "anything else" case.

I don't follow. Please elaborate.

And what other way of checking variables against NULL did you have in mind?

That looks a lot like the original question. David is one of our best answerers. If you want his help, and he asks you a question.... You should answer it, or give up on people helping you.

printf("\n\n%s", p1 ? "p1" : (p2 ? "p2" : (p3 ? "p3" : "none")));

Hi friends,
We develop an application under MSVC++ 2005 and now my task is to remove the memory leaks. In fact I found some problems especially “new” and “delete” instructions that aren’t paired and also some cases when they was inappropriate used. The main problem is the memory used by the app. When I run it multiply time the total used memory reported by Windows Task Manager increases (between two playing the difference of memories isn’t the same in generally). I suspect that the problem isn’t memory leaks. Can u help me with any advice?
Also as memory leaks I have some reported by MSVC library, how can I identify the exactly cause in my source for these, e.g:
f:\rtm\vctools\vc7libs\ship\atlmfc\src\mfc\map_pp.cpp(69): 68 bytes, allocating 'Normal' block (#155028)
f:\rtm\vctools\vc7libs\ship\atlmfc\src\mfc\plex.cpp(29): 124 bytes, allocating 'Normal' block (#155030)
f:\rtm\vctools\vc7libs\ship\atlmfc\src\mfc\map_pp.cpp(69): 68 bytes, allocating 'Normal' block (#274094)
Thanks in advance for your support

In this situation MemoryValidator,BoundsChecker or alike developer tools may help. Try trial for free.

Thanks, I tried a lot of memory leaks detector software (included those indicated by you) but they did't give me useful information, this is the cause that make me to think that the memory increse when I "Play" multiple time has another cause.

The numbers from TM are not telling you how much memory your program is consuming. They are the amount of address space that is in use, which will be less than the amount of address space your program is actually using.

Thanks David, maybe u are right, can you give me more info about this, it is the fist time when I heard about it (TM ). How can i find the exactly amount of memory used by app?
have a nice wked

Maybe the Performance Monitor has something you can use (e.g., Process(yourprocess)\Private Bytes).

I want to load a codejock skin,but not msstyles,
Does any body have and would like to share it?

You'll have to buy something that's sold for money. Nobody here is going to share it with you.
However, you could take a look at The Ultimate Toolbox Application Skins[^], which is free for use.

Hi guys,
I'm trying to make a routine that save an icon (HICON) to png file with GDI+
Bitmap* bmp = new Bitmap(icon);
GetEncoderClsid(L"image/png", &encoderClsid);
bmp->Save(L"xxx.png", &encoderClsid, NULL);
So far so good. But when I open the png ... it is not transluctant (semi transparent).
Any ideas why???
And I found that GDI+ has A LOT of problems with icons 
P.S. If you have another suggestion how to do this, please share fragment of code.

I'm not sure that you can do this directly as you suggest. Icons are 'special' file types that Windows understands and paints in a slightly different manner to ordinary bitmaps. Take a look at Icons in MSDN for more information.

Is my question so hard? Nobody had similar experience?
