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?

but those value can't be display and i think that value especially
*name don't save into video file.
how about complie with your computer?
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?

Because with a free skin library, I can save a lot of time. I don't have much free time by now.

If you dont have a free time so librarys are good.;)

Hi All,
After inserting a item is Explorer's shell, one must call DrawMenuItem( hWnd ) to to update the menu. However, the code which inserts the menu item does not receive an hwnd. Any ideas how to obtain the hWnd from an hMenu? Below is the context which DrawMenuBar() would have.
Jeff
HRESULT CTest::QueryContextMenu( HMENU hmenu, UINT uMenuIndex,
UINT uidFirstCmd, UINT uidLastCmd, UINT uFlags )
{
uidLastCmd;
if( uFlags & CMF_DEFAULTONLY )
{ return MAKE_HRESULT ( SEVERITY_SUCCESS, FACILITY_NULL, 0 ); }
if( m_count > 1 )
{
InsertMenu( hmenu, uMenuIndex, MF_BYPOSITION,
uidFirstCmd, _T("String 1") );
}
else
{
InsertMenu( hmenu, uMenuIndex, MF_BYPOSITION,
uidFirstCmd, _T("String 2") );
}
HWND hwnd = null;
DrawMenuBar( hwnd );
return MAKE_HRESULT( SEVERITY_SUCCESS, FACILITY_NULL, 1 );
}

An old VC++ thread yielded this:
Christian Astor wrote: You can use FindWindow("#32768", NULL);
(eg on WM_INITMENUPOPUP)
IMHO, the belief here is that you will be able to find the active Menu's window by that special ID.
Good luck!
Peace!
