Hi,
I have a custom develpoed ListControl which have combobox in it. I wrote the code to notify the ListControl about the SelectionChange in ComboBox by writing a Windows User Defined Message.
void CComboBoxExt::OnSelChangeCombo()
{
....
GetParent()->SendMessage(UWM_NOTIFYSELCHANGE,nRow,nCol);
}
Now in the Parent Control ( here ListControl ) I want the ListControl to send the message LVN_ITEMCHANGED which is the message sent by thewindows framework when an item in the ListControl is changed, so the end user doent need to handle a seperate my own created message.
ON_MESSAGE(UWM_NOTIFYSELCHANGE,OnChildSelNotify)
void CListCtrlEx::OnChildSelNotify(int nRow,int nCol)
{
GetParent()->(LVN_ITEMCHANGED,);
}
My query is which structure should I send as the paarmeter ? The Handler function for LVN_ITEMCHANGED takes pointer to NMRHDRSTRUCTURE. Any help will be appreciated.
Thanks

char* t1 = "C:\\a.txt";
char* t2 = "C:\\b.txt";
char* t3 = "c:\\c.txt";
(VC++6.0)please guide I copy content of 2 a and b to c ???. thanks very much
I coded ERROR. open binary ==> it will read \r\n ==>error
e.g:
file a.txt
ABCDED
file b.txt
DDDDDDDDD
file c.txt. ==>>
ABCDED
DDDDDDDDD
content coded
bool copyFile (const char SRC[], const char INPUT2[], const char DEST[])
{
std::ifstream src; // the source file
std::ifstream input2;
std::ofstream dest; // the destination file
src.open (SRC, std::ios::binary); // open in binary to prevent jargon at the end of the buffer
input2.open(INPUT2, std::ios::binary);
dest.open (DEST);//, std::ios::binary); // same again, binary
if (!src.is_open() || !dest.is_open())
return false; // could not be copied
dest << src.rdbuf (); // copy the content
dest << input2.rdbuf();
dest.close (); // close destination file
src.close (); // close source file
return true; // file copied successfully
}

else
std::cout << "File copied successfully!";

Not quite sure what your question is.... I've tried your code, and it does indeed copy the contents of a.txt and b.txt to c.txt
If I have \r\n in the input file, it is copied. If I do not have it, it's not copied. The code functions as it seems it should. What were you expecting, may I ask?
Also, have you tried looking at the text files with a hex-editor? Some text editors automatically insert \r\n at the end of the file when you save it, even if you didn't want them there. E.g Code::Blocks editor.
Also, if you put the line
using namespace std;
up in the top of your code somewhere, you can avoid having to type std:: all over the place.
Here's the code I tried.
#include <iostream>
#include <fstream>
using namespace std;
bool copyFile (const char SRC[], const char INPUT2[], const char DEST[])
{
ifstream src;
ifstream input2;
ofstream dest;
src.open (SRC, ios::binary);
input2.open(INPUT2, ios::binary);
dest.open (DEST);
if (!src.is_open() || !dest.is_open())
return false;
dest << src.rdbuf ();
dest << input2.rdbuf();
dest.close ();
src.close ();
return true;
}
int main(int argc, char* argv[])
{
if (!copyFile ("a.txt", "b.txt", "c.txt"))
cout << "File could not be copied successfully";
else
cout << "File copied successfully!";
cin.get ();
return 0;
}

Hi
How can i convert
const std::string& sMyString
to a CString ?
Can anyone help
thanks
Simon
|
|
|
|
|
what about reading the docs first ?
did you see the method std::string::c_str() ?
std::string s = "hello";
CString str = s.c_str();

that's right.
otherwise, the following should do it :
CString str = CA2T(s.c_str());
|
|
|
|
|
Or simply use std::tstring[^], then it does not matter if UNICODE is defined or not.
|
|
|
|
|
I didn't know the std:: namespace had implemented such a container...
or is it MS that voluntarily pushed themselves into the std namespace (which is normally reserved to the C++ standard only) with such ?
(BTW, i don't have a compiler now, and lazy to search for more myself, so, just curious, how is it defined ? i'd bet for namespace std { typedef basic_string<TCHAR> tstring; }... what it is actually ?)

don't mind for the mail, I just understood.
so YOU are pushing code into std, ha ?! lol
well, the coding looks clean enough. it's ok for this time. you can pass your way

Hello,
I am havin a problem with including file.
I made one file where I put all the file needed by other classes.
includes.h
#ifndef MY_CLASS1
#define MY_CLASS1
#include "myclass1.h"
#endif
#ifndef MY_CLASS2
#define MY_CLASS2
#include "myclass2.h"
#endif
...
and in my cpp file I just write #include "includes.h".
The problem comes up when some class inherit from other. I get the error that the identifier of some class is unknown, or that the class is redefined.
Another question: Is it possible to have as member of base class an object of a class inherited from that base class?
Thank you for your replys, Tomas

Why don't you use only once the include guards in your file ?
#ifndef _INCLUDES_H_
#define _INCLUDES_H_
#include "MyClass1.h"
#include "MyClass2.h"
Of course, you need to have include guards in the specific header files also.

No, unless it is a pointer to the object (and you use a forward declaration of the class).

If I were you I'd stick to 1 header per class and include what you need where you need it. trying to include everything through 1 header is never really going to work.
Tomas(cz) wrote: Is it possible to have as member of base class an object of a class inherited from that base class?
No, many people would say that's what pointers are for (except the Java Bunnies) Just add a base class pointer as a member of your base class and then later you can use it to point to instances of derived classes, how cool is that

I want that the left bottom be (0,0), and y increases upward.
Here are two ways, why the 1st not work?
1
Matrix matrix(1,0,0,-1,0,0);
g.SetTransform(&matrix);
g.TranslateTransform(0.f,REAL(drawing_rect.Height));
2
Matrix matrix(1,0,0,-1,0,drawing_rect.Height)
g.SetTransform(&matrix);
system

I'm sorry if this is a stupid question but my C knowledge is VERY small - almost zero!
I'm creating a C# wrapper around some C functions and in the header file there is
typedef long long int Samples; I get the typedef idea, but why more than one type-declaration?

Because in C, long long int is a type (64 bits integer). See here[^].
|
|
|
|

Ah, now I get it, long int in C == int in C#, long long int in C == long in C#. Thanks
