I think I could decode his question.
Mr.CPallini sir ,
He has two buttons on the dialog and when he clicks each button it makes a thread they work very well now he wants that either buttons makes a single thread is it possible and if yes do you have any idea?
(what do you think it was a good decode;))

Hello everyone,
I am wondering what is the practical usage of unary_function? Could anyone list some practical benefits?
My question is, a class like
class Foo : public std::unary_function<class A, class B>
is always the same (could use similar implementation) to
template <class A, class B> class Foo
So we could always use the alternative approach to replace unary_function.
thanks in advance,
George

No isn't the same. You must adhere to the interface while inheriting. (That's not the case of template <class A, class B> class Foo).

first, sorry my english is a little^^;
i type a cod about binary search.
first, i make Video class.
and i want video class to save some andy txt file.
this is my code.
i think ,
there is some problem at write method.
but i don't know why it is happened....
please give me your advice~
#include<iostream>
#include <string>
#include <fstream>
using namespace std;
class Video
{
private:
char *name;
int number;
public:
// ifstream fin;
// ofstream fout;
Video()
{
name = new char[30];
strcpy(name , "nothing");
number = 0;
}
Video(char *imsi_name, int imsi_number)
{
name = new char[strlen(imsi_name)+1];
strcpy(name, imsi_name);
number = imsi_number;
}
int Get_number()
{
return number;
}
char *Get_name()
{
return name;
}
void Set_number(int k)
{
number = k;
}
void Set_name(char *imsi)
{
delete[] name;
name = new char[strlen(imsi)+1];
strcpy(name, imsi);
}
};
void main()
{
Video *v[100];
Video *v4[10];
Video v3;
int i; //point index
ifstream fin;
ofstream fout;
fout.open("c:\\video3.txt", ios_base::out | ios_base::app | ios_base::binary);
fin.open("c:\\video3.txt", ios_base::in | ios_base::binary);
v[0] = new Video("kk1", 1200);
v[1] = new Video("kk2", 2200);
v[2] = new Video("kk3", 3200);
// cout << sizeof(Video) << endl;
// cout << sizeof(kk) << endl;
// cout << sizeof(kb) << endl;
//cout << v.Get_number() << " " << v.Get_name() << endl;
//cout << "size of v" << sizeof(v) << endl;
for(i = 0; i < 3; i++)
{
fout.write( (char*)v[i], sizeof(v3) );
i++;
}
fout.close();
// while(fin.read( (char*)&v3, sizeof(v3) ))
//
// {
// cout << v3.Get_name() << " : " << v3.Get_number() << endl;
//
// }
//cout << "size of v4: " << sizeof(v4[0]) << endl;
i = 0;
while(fin.read( (char*)v4[i], sizeof(v3) ) )
{
cout << v4[i]->Get_name() << " : " << v4[i]->Get_number() << endl;
i++;
}
}//main
Thank you!!

What do you want to do with write and what is happening instead?

sorry, my explanin is not good~
v[0] = new Video("kk1", 1200);
v[1] = new Video("kk2", 2200);
v[2] = new Video("kk3", 3200);

You have to explicitely write the string inside the file. You can do it also with a method of your class.

I gave a better look at your code, probably you need object serialization, i.e. a rather difficult mechanism for a beginner. Since MFC supports object serialization http://msdn2.microsoft.com/en-us/library/6bz744w8(VS.80).aspx[^], using this class library maybe an advantage.

I tried "MoveWindow", there is a problem.
GetClientRect(&rt), rt.top is 0, after change rt.left, and MoveWindow, the toolbar will be covered by the new client. The coordiantes are not consistant.
I also tried "SetViewportOrg", it works well, however, if MoveWindow can work properly, I will choose MoveWindow to implement it for less problems in the future.

Have you tried CControlBar or any of it's derivative classes?

Never, I'll try.

#include <stdio.h>
#include <stdlib.h>
void main()
{
FILE *in, *out;
int i;
char str[100];
clrscr();
in=fopen("B.txt","r+");
if(!in)
{
printf("can not open input file");
exit(0);
}
out=fopen("newB.txt","w");
if(!out)
{
printf("can not open output file");
exit(0);
}
while (!feof(in))
{
fgets(str,100,in);
//for(i=0;str[i]!=null;i++)
fputs(str,out);
fclose(out);
fclose(in);
}

Did you see this link I think it sovles your problem when you it finds words you can insert them to a array(like CStringArray) and then make a new file with CFile class and use of CFile::write.

I tested CCJButton, but find nothing special,
even worse when CButton is replaced with CCJButton, I move the mouse onto the button, the text is disappeard.
I think CJ60Lib in my project is not working properly.
Is there any document or examples?
