Not replying to Max but more to the thread... I need to establish source control on a multideveloper VIsual Studio project. Early on, we ran into problems with two or more developers working in the UI area. Merges just didn't happen easily. What we do now, and it has never failed us, is that we have a baseline project, and we cut/paste new dialogs from the new projects to the baseline. This ends up copying all of the dialog description plus the binary stuff at the end (VS knows how to completely copy the dialog object....).
Stop groaning - it works, and we were new to the IDE 18 months ago.
Now, I see that people just "check in" their new resource files, and, assuming there are no resource conflicts, Visual Source Safe knows how to merge the resource files correctly?
I know, I know - try it, and I will, but I'd like someone to confirm that it should work like this.
Thanks

Hi to everybody,
I am developping a graphic ActiveX that displays several IP addresses around a circunference and linked between them. it can occur that if there are a lot of IPs, they couldn't be seen properly. For that I would like to be able to zoom an area of the screen.
Is there any possibility to do this easily?
Thank you very much.
Javier

I have a structure which composes of structures , which is further nested with structures and the nesting goes for a certain depth .If i use this main structure in a class i have to initalize the whole of the structure their nested mambers which takes a lot of overhead while coding .Is there a faster way ot initialize this?
for eg:-
typedef struct
{
A *a;
B *b;
}Main;
typedef struct
{
A1 *a1;
A2 *a2;
}A;
typedef struct
{
A11 *a11;
A12 *a12;
}A1;
similarly for A2,B,B1,B2......and so on for all the nested members. if i have to use it in the class it takes a large overhead while initialising all the members using 'new' operator . Is there a better way of redesigning this coding?
hitherto shall thou come but not further thee

One alternative would be to initialize structure each in its own constructor.

How does one convert WCHAR to wchar_t?
I am the handsome one in the crowd.
|
|
|
|

No conversion needed.
WCHAR is wchar_t typedefed
typedef wchar_t WCHAR;

TCP is a connection-oriented protocol, UDP (User Datagram Protocol) is a connectionless protocol. Can some one tell me the simple meaning or a scenarion of connectionless connection ?
|
|
|
|
|
if i remember well (not sure at all so  ) you can use UDP when you send packets to a whole network (not a determined peer).
now, if anybody knows much, i give up

TCP provides reliable data delivery, while UDP does not.

In simple terms, TCP is like a telephone call, where UDP is like a radio. Anyone who wants to listen to the radio must tune in to the proper station, or for UDP, they must "join" to the proper network address.
The radio station doesn't know or care who is listening (other than marketing and ratings, of course), just as the UDP sender doesn't worry if packets are lost or dropped. One use is for sending streaming video or audio where the sender just sends and whoever has "joined" gets to see the show.

Please some go through the code for UserCreate dialog and
give me the reason why i could not able to see the text box fields
as there are more than six and seven dialogs being called in Mainframe.cpp file. Each dialog has gone through the MFC App wizard
as this is the MFC SDI application calling ATL Dlls through COM+
instantiation.Please help me out whether I need to overload the
constructor in UserCreate class which MFC App is not allowing me to do
or any other suitable way to get it done as first as possible.
OnOk handler of UserCreate dialog, I could not see the entered data
in text fields while debugging. Please help me out if anyone knows.

Have they been added to the IDD_DIALOG_CREATEUSER dialog template?

The api GetTimeZoneInformation returns the TimeZone.The 'StandardName' variable of TIME_ZONE_INFORMATION structure is unsigned short[32].How can I check if the time zone is IST or so?Please explain.I am in need of this very much.

You can use _wcsicmp function to check it.

Write a C++ program that has class
1) math
Our math class has only one data member number and member function display that will display the data member number.
Write the constructor of our math class that will initialize the data member number with the value zero.
Our program will overload the following operators.
1. Plus +
2. Minus -
3. Multiplication *
After overloading these three operators our program will be able to add, subtract and multiply our math class object with the integer in main() after overloading these operators we should be able to write these statements in main().
math obj1, obj2;
obj1= obj2 + 10;
Above statement will call the member function operator + () and will add the 10 in the data member of obj2 and finally will return the math class object. Similarly we also overload the multiplication operator * and minus operator – so that our math class object will be able to multiply and subtract from integer values.
Also our plus + overloaded operator should be intelligent enough to accommodate the following statement in the main() function.
math obj1, obj2;
obj2= 10 + obj1;
for this we will have to write friend function that will be called automatically and will add the integer value 10 in the data member of obj1 and finally will return the math class object . Similarly write two more friend functions that will overload the multiplication and subtraction operator so that we will be able to write the following statement in the main() function.
math obj1, obj2;
obj2= 10 *obj1;
obj2= 10 - obj1;
Output should be similar to the following:
Sample output 1:
adding integer 10 in the object using statement: obj= obj + 10 ;
10
adding integer 10 in the object using statement: obj= 10 + obj;
20
Multiplying object with integer 20 using statement: obj= obj * 20 ;
400
Multiplying integer 20 with object using statement: obj= 20 * obj ;
8000
Subtracting 20 from object using statement: obj= obj - 20 ;
7980
Subtracting object from 10 using statement: obj= 10 - obj ;
-7970
The Code i wrote is below:
#include <iostream.h>
#include <stdlib.h>
#include <conio.h>
class math
{
private:
// Private data member of the calss math
int number ;
public:
// Constructor for math class
math() : number(0) {}
// friend functions
friend int operator+(int,math);
friend int operator-(int,math);
friend int operator*(int,math);
};
// Main function of the programm
void main ( )
{
math m1,m2 ; //create an object of class myClass1
int obj2;
cout << "adding integer 10 in the object using statement: obj=obj + 10 "<

Wow, I can see that the copy/paste functionality works fine on your computer  .
Ok, but what's the question ? You want us to do your homework for you maybe ?
You will have more success if you post SPECIFIC questions, for the parts where you are stuck. Also, try to use the formatting tags when posting code !

What errors? Compiler, linker, run-time, assertion, exception, etc. Have you single-stepped through each line of code to see where you get unexpected results?

You need to put the operator functions as member functions of the class (so first parameter of the function will be implicitly the this parameter). And you'll have to remove the * in the definitions of these function (return an int not a int* ).
You have luck that I'm in a good mood. Honnestly your post only deserve a 1. There is no specific question, you just want us to go through your code without giving us the errors, there is no formatting, you just made a copy paste of your homework and you don't even have the respect to use correct english.

ok, i'll not repeat what cedric already told you, but if you think a liitle on your code, you could see this :
you return an int*.
firstly, we use to return references instead of pointers when coding operators overloads.
secondly, do you really want here to modify the value of the operands ?
if you consider the operation : 2 + 2, i should return 4, but not modify none. moreover, which part would you modify here ? 2 (non l-value) ?!
so, just return an int...
and don't forget !!! reflection is the begining of a good code !  ;P

i won't give you the entiere solution (as homeworks are for grow up self knowledge), but i give you a start point by designing a good class (i changed the class name into CMathCalc to avoid redefining a supposed existing math identifier) :
MathCalc.h
<font color=blue>class</font> CMathCalc {
<font color=blue>double</font> m_Data;
<font color=blue>public</font>:
<font color=green>
CMathCalc();
CMathCalc(<font color=blue>double</font>);
<font color=blue>virtual</font> ~CMathCalc();
<font color=green>
<font color=blue>double</font> Display() <font color=blue>const</font>;
<font color=green>
<font color=blue>double operator</font> + (<font color=blue>double</font>) <font color=blue>const</font>;
<font color=blue>double operator</font> - (<font color=blue>double</font>) <font color=blue>const</font>;
<font color=blue>double operator</font> * (<font color=blue>double</font>) <font color=blue>const</font>;
CMathCalc& <font color=blue>operator</font> = (<font color=blue>double</font>);
CMathCalc& <font color=blue>operator</font> = (<font color=blue>const</font> CMathCalc&);
<font color=blue>double</font> <font color=blue>operator</font> + (<font color=blue>const</font> CMathCalc&) <font color=blue>const</font>;
<font color=blue>double</font> <font color=blue>operator</font> - (<font color=blue>const</font> CMathCalc&) <font color=blue>const</font>;
<font color=blue>double</font> <font color=blue>operator</font> * (<font color=blue>const</font> CMathCalc&) <font color=blue>const</font>;
<font color=blue>friend double operator</font> + (<font color=blue>double</font>, <font color=blue>const</font> CMathCalc&);
<font color=blue>friend double operator</font> - (<font color=blue>double</font>, <font color=blue>const</font> CMathCalc&);
<font color=blue>friend double operator</font> * (<font color=blue>double</font>, <font color=blue>const</font> CMathCalc&);
};
<font color=green>
<font color=blue>double operator</font> + (<font color=blue>double</font>, <font color=blue>const</font> CMathCalc&);
<font color=blue>double operator</font> - (<font color=blue>double</font>, <font color=blue>const</font> CMathCalc&);
<font color=blue>double operator</font> * (<font color=blue>double</font>, <font color=blue>const</font> CMathCalc&);
ok, i think you have enough information now to have a good mark...
