You may go on with the weird tricks and build and object on the fly, for instance (only to give you the idea):
#define WRAP(i) Wrap(i, #i)
struct Wrap
{
int _i;
string _s;
Wrap(int i, string s):_i(i), _s(s){}
};
ostream & operator <<(ostream & o, Wrap w)
{
o << w._s << "(" << w._i << ")";
return o;
}
void main()
{
int i;
i=5;
cout << WRAP(i) << endl;
}

then I would say it is not wise to suggest to be in position to question God's choices, or in position to be able to give
consultance or advice to God Almighty. becuase since God the Almighty is the all wise, the all creator, then
the maximu wisiness I or any human can achive is to admit that the creature can not be wiser than its creator, the one who
created its head, way of thinking, algorithm and memory,etc.
i hope you accept my comment.
I accept your comment, of course.
BTW I hope you enjoyed the irony of Alfonso and, after all, that went on my arrogant assumptions...

Thank you again Mr Pallini ! This solvs the problem with primitive types.
Of course I will do it : the people of JAVA and C sharp and Scala and the others have permitted to theirself to accept that the simple instruction be implemented and behinded by throusands of translation instructions.
If such thing as the onthe fly create of a struct wrapper of a primitive type only would have a minor effect at the parameters collection before the actual serialization process, and that in the reverse it will help users not need to precise the name of the primitive type vriable, next to the value of it, then it is OK, it is acceptable and I permit myself to do it !
Thank you again.
I have to laugh at myself indeed at recognizing that that sentence on which I commented was a joke !

If you create objects with name you have the possibility.
MyOb
{
Cstring name;
int values;
};
Func( MyOb b );

yes for objects I have no problems. I alreeady created a base class with base key data member that will be queried upon inside Func howsoever the b object is (of course it sould be a derivative of my base).
Thnk you for your intervention.

So i only have pbm with primitive data types like int, CStrng, etc for which I need to supply the actual vriable name.

That is bad design. Take one mental step back and think what you want to *Do*.
You need to transport information about a WHAT (your variable value) and a HOW into your function. You can either introduce another parameter (as already posted).
Alternatively, and more "The C++ way" would be to use different parameter types and overloading.
class Strategy
{
public:
Strategy( int Value}
: m_value( Value)
{}
int GetValue(){ return value;}
private:
int m_value;
}
class StrategyA : public Strategy
{
StrategyA( int Value) : Strategy( Value)
{}
}
class StrategyB : public Strategy
{
StrategyB( int Value) : Strategy( Value)
{}
}class StrategyC : public Strategy
{
StrategyC( int Value) : Strategy( Value)
{}
}void Function1(StrategyA iArgument)
{
}
void Function1(StrategyB iArgument)
{
}
void Function1(StrategyC iArgument)
{
}
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

yes yes I am totally with you.
but for primitive types I needed that sort of trick which M Pillini game me so to automatically grad the variablke name and not oblige the developer to explicitly put a key name next to the var value.
it is also useful since he may forget to supply the wrong key name in the reverse process (reading process as opposed to storing, or receiving as opposed to sending the primitive var).
As for object, yes indeed I have the things that you explianed. More thnat that and since I may have differente types of objects serialized in same stream to be sent or saved to disk, which havce same key, then I need to add a type data member to the base class.
class CSerializeObjBase
{
public:
CSerializeObjBase(CString key,CString objType)
{
this->key=key;
this->objType=objType;
}
CSerializeObjBase(int key,CString objType)
{
this->key.Format(_T("%d"),key);
this->objType=objType;
}
~CSerializeObjBase(void){};
private:
CString key;
CString objType;
public:
void setObjKey(CString key){
this->key=key;
};
CString getObjKey(){
return key;
};
CString getObjType(){
return objType;
}
virtual bool serializeObject(CPacketBase* pStore){
return false;
};
};
Thk you for your intervention; and forgive the bad words, bcuase i am arab and consume time to formulate right sentences in english ans i am hurry now but i recognize the necessity of replying to you and thanking you.
So Thank you for your help.

i want to add for you all before i go to take the bus, that indeed i could have given up the necessity of exploiting of vraiable naming information, and rather exploited the simple order by which the variables or objects are put in the stream, in the serialisation process wether while writing to file or db or sending to network.
becuase in the reverse process the developer will have to take care of th e exact reverse order of fetching stream elkemnst onto vraiables and memebers of the object or objects obnside the object.
I am in a bad position. the java and C# people have an interprested lalgage so it is possible for them to query an unknow object type and ask it for its type and even query oits memùbers and even functions.
Thus it is easy for them to consstruct automatic tools for sending objects and i do'nt know.
for me i have many personal unmanaged C++ programs and i want besides to take the strategic decision of staying with unmanaged code. but of course i can not accept to be bypassed by the java and the C sharp people so i must do something even though C++ is not interpreted.
Thank you.

Hi,
I have an MFC app for which icon is displayed normally in all conditions except this -
- When I open 2 instances of the app and Windows XP groups them into 1 single entity in taskbar, the icon displayed is something other than my app original icon.
Any ideas regarding this ? (I'm already doing a SetIcon btw at my side)
Regards
Cage

Have you changed all resolutions of your icon? In one .ico file can be several sizes (16x16, 32x32, 48x48).

Okay. So, you mean to say I should have 3 sizes images embedded into the ico file ?
The way I created the icon was to use create a 32 * 32 size icon.
Btw - how can we see for an ico file - how many sizes does it support ?
Thanks for the help,
Cage

I use Visual Studio's built-in icon editor.

Ok. so I just added 16 * 16 as well as 48 * 48 image sizes to my icon. I can see all 3 sizes - 16, 32 and 48 in my visual studio icon editor.
But my problem still continues ...
As I told you earlier - I can see the icon fine in the titlebar, in the icon which shows up when you do an alt+tab but I see the default icon(hand with videocamera) rather than my app icon in taskbar properly when I have more than 1 instances open for my app and windows xp has "grouped" them into 1 with its taskbar setting.
1 part which I missed earlier was even in the xplorer view, the icon for my app is that default one instead of original app icon.
Thanks for your time,
Regards
Amit

The app icon is sometimes tricky. Best is to give it the lowest icon ID in the resource.h.
And as some rightly mentioned support all possible sizes and bit depths in the icon.

I second that. I had a similar problem which was solved by doing this

Hi all,
please tell me how can i convert CString to float or vice Versa.
i m using this,
float fvar;
CString foo;
foo = "123.45";
fvar= atof(foo);
but this not working.
Please tell me.
Thanks in advance.

No there is no error message.
but after calculation the final resul is Zero, that is wrong.

The only reason that I can think of that neither code works is that the string contains some other character before the numbers. atof will strip off any leading whitespace characters (MSDN says spaces and tabs only, but in my testing it also strips of newlines). Any other characters, probably including non printable characters, could cause it to return zero. Have you checked the characters in your string?

Its working fine in my dialog based testapp. I could find only one warning -
"warning C4244: '=' : conversion from 'double' to 'float', possible loss of data".
Since atof() returns double instead of float.

Jijo.

is "." the right comma sign, or "," It depends on the system settings.
Set the warning level of the compiler higher to get a message. It also should work harder.
(Use double)

I answered this for you on Codeguru, but in case you visit here more often...
The most likely reason I can think of (since you don't explain "not working" is this...
If you application is Unicode (default for VS2005 and later) then you can either change it to MBCS, or change your code to:
float fvar;
CString foo;
foo = _T("123.45");
fvar= _tstof(foo);
This change will allow it to work with either Unicode or MBCS.
Hope that helps.

You can always use std::stringstream and the << operator instead of the old, insecure C-ish atof.
