I think this will work.
You need to add a public member function BOOL HandleChildEnum(HWND) to your view class.
If this does not work, then you can not enumerate from within the OnInitDialog, and a message will have to be posted to yourself to cause the enumeration.
// global function maps from global space to class space
BOOL CALLBACK MyEnumChildProc(
HWND hwndChild,
LPARAM lParam
){
// lParam was apointer to 'this' a C_PropView
C_PropView* pMyView = (C_PropView*)lParam;
// now call function within context of the class data
return pMyView->HandleChildEnum(hwndChild);
}
// now you have access to all your member variables and are within t he // context of your class BOOL C_PropView::HandleChildEnum(
HWND hWindowChild
){
return TRUE;
}
// call the child window enumerator
// make sure
BOOL C_PropView::OnInitDialog()
{
// make sure to call base class
// first, so all the MFC crap is initialized
CDialog::OnInitDialog();
// enumerate child windows
// passing in our window, the local function, and a point to 'this'
::EnumChildWindows(m_hWnd, MyEnumChildProc, (LPARAM)this);
}

Hy,
That depend on what you need, char = 0x07 or char = '7' 
|
|
|
|

char = '7'

You can use on of :
sprintf, itoa ...
of this pseudo code
<br />
int = nex_digit<br />
while(int)<br />
char = 0x30+int

I would like to run this function in my C++ code;
void convertToBinary( int numberToConvert )<br />
{<br />
if(!(( N / 2 ) < 1 ))<br />
{<br />
binaryRepresentation[counter] = ( N % 2 );<br />
counter++;<br />
convertToBinary( N /= 2 );<br />
}<br />
}
but binaryRepresentation[counter] = ( N % 2 ); line of code does not work friend?

I don't understend what meen N in this code
For binare representation of value i use this function:
<br />
char* BinPrintf(int value)<br />
{<br />
char tmp[256];<br />
memset(tmp, 0, 256);<br />
int tpos = 0;<br />
<br />
while(value)<br />
{<br />
tmp[tpos++] = 0x30+value%2;<br />
value = value >> 1;<br />
}<br />
<br />
char *ret = new char[strlen(tmp)+1];<br />
memset(ret, 0, strlen(tmp)+1);<br />
tpos = strlen(tmp)-1;<br />
value = 0;<br />
while(tpos > -1)<br />
ret[value++] = tmp[tpos--];<br />
<br />
return ret;<br />
}<br />

This code could simply be replaced with a call to strrev(tmp).

I assume binaryRepresentation is some sort of char array, and that N is actually numberToConvert. That being the case, what you have is working, but you are confusing 0 (ASCII 0) and '0' (ASCII 48). You simply need to change the statement to:
binaryRepresentation[counter] = (char) ((N % 2 ) + 48); Now binaryRepresentation[counter] will contain '0' if N is an even number and '1' if N is an odd number.
Of course, if you wanted to use a "built-in" solution, you could simply use itoa(numberToConvert, binaryRepresentation, 2).

<font color=#0000FF>char</font> c;
sscanf("7", "%s %c", &c);

When I made
sscanf( static_cast<char>( N % 2 ) , "%s" , &binaryRepresentation[counter] );
Compiler gives an error like
cannot convert parameter 1 from 'char' to 'const char *
I'm a newbie in C++,

that's normal, you associate a char with %s
do this :
sscanf( static_cast( N % 2 ) , "%<font color=#FF0000>c</font>" , &binaryRepresentation[counter] );
TOXCCT >>> GEII power

When I type;
sscanf( static_cast<char>( N % 2 ) , "%c" , &binaryRepresentation[counter] );
Same error occurs, cannot convert char to const char*

That is because static_cast( N % 2 ) is not a pointer to a char. I don't know what it is, because N is unknown to me...
Take a look at the prototype of sscanf[^] and then start wondering how you should pass the parameters...
Besides that, the solution that Mad__ gave you looks like what you want... 
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

Hello all,
In application I am facing handle leak problem.
I am using dev partner tool and oh.exe from MS to trace the leak. But after getting the information from oh.exe I am unable to understand how to get in the code.
for example: using oh.exe i can find that
" 00000ADC gpb.exe File 09e4 \DOCUME~1\E669267\LOCALS~1\Temp\~DFB472.tmp " handle is getting leaked.
Now can you suggest how to locate code with respect to this leak.
Thanks & regards,
Jokhan

Hi,
Think u must have 2 use something like
CMainFrame *pFrame = (CMainFrame *) GetParentFrame();
TBBUTTONINFO tbi;
tbi.dwMask= TBIF_STYLE;
tbi.cbSize= sizeof(TBBUTTONINFO);
pFrame->m_wndToolBar.GetToolBarCtrl().GetButtonInfo(ID_FILE_SAVE, &tbi);
tbi.fsStyle |= TBSTATE_PRESSED;
pFrame->m_wndToolBar.GetToolBarCtrl().SetButtonInfo(ID_FILE_SAVE, &tbi);
Sometimes this may help u

is there any way i can trace the function where the breakpoint function was reached. I've tried the "crash finder" application but that couldnt trace the function either. I've put exception handlers all over but the application crashes at some point. The application always crashes at the same address and i cant really trace the condition where this is happening. I am writing all my the function names in a file to trace the condition but the application breaks off at a different point with the same address location. Any ideas people?

|

have a look at the functions call stack, the processor registers and so useful debuging tools.
otherwise, if you want some help, post a piece of the crashing code...

Have a look at the project's .map file (you might have to add /map to the linker settings). For example, if you know the program is crashing at address 0x17d28a03, you would look in the .map file for the closest address that is less than this value.

Does anyone know of a (preferably free) class library that will accurately represent decimal numbers? we have been using floats but these have problems representing certain numbers and are resulting in rounding errors.

|
|
|

could you explain a bit more ?
i don't understand why you're talking about a class for integers.
don't you want to use signed/unsigned int/short/long ??
