Take a look at the listview notification messages, there are many there that would do the job, like NM_HOVER, LVN_HOTTRACK and LVN_GETINFOTIP. Most of it depends on how you have created the listview, what styles you applied and how you added icons.

You will need to subclass the window

i wrote the same code both in VISUALL C++ AND C#. in both cases, the OPTIMIZED SWITCH is turned on. the results: in C#, around 300 msec, in c++ less then 1 msec.
what is happening here??? in general i need to process 4 megabyte each 250 msec, and it looks likt c# is not the answer... or maybe there is another optimize switch in c# i am not aware of (beside the one in the BUILD TAB). can someone please advice? is it true c# is not good for real time?
THE CODE in visual studio 2005 c#:
===================================================================================
using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics ;
namespace ConsoleApplication10
{
class Program
{
static void Main(string[] args)
{
byte []byte1=new byte[2097152*2];
byte[] byte2=new byte[2097152*2];
Stopwatch sw=new Stopwatch ();
sw.Start ();
for(int i=0;i<2097152*2;i++)
{
for(int y=0;y<64;y++)
{
if(byte1[y]==byte2[y])
//if (*(bytes1+i)==*(bytes2+i))
{
}
}
}
sw.Stop ();
Console.Write ("{0}",sw.ElapsedMilliseconds ) ;
Console.ReadKey ();
}
}
}
THE CODE IN VISUALL C++ 2005:
===============================
#include "stdafx.h"
#using <system.dll>
#using <system.drawing.dll>
#using <system.windows.forms.dll>
using namespace System;
using namespace System::Diagnostics;
using namespace System::Windows::Forms;
using namespace System::Drawing;
using namespace System::Drawing::Drawing2D;
int _tmain(int argc, _TCHAR* argv[])
{
char *bytes1=new char[2097152*2];
char *bytes2=new char[2097152*2];
Stopwatch^ stopWatch;
stopWatch = gcnew Stopwatch;
stopWatch->Start ();
//for (int u=0;u<10000;u++)
for (int i=0;i<2097152*2;i++)
{
for (int y=0;y<64;y++)
{
if (bytes1[y]==bytes2[y])
//if (*(bytes1+i)==*(bytes2+i))
{
}
}
}
long ii;
ii =(long)stopWatch->ElapsedMilliseconds;
stopWatch->Stop ();
printf("%d",ii);
//ElapsedMilliseconds Ticks
return 0;
}

Hi i am a chiptuner that programs my own software for cars..
Now i want to start writing small interfaces and checksumm algorytm, and i have just started to look at the visual c++
Anyone that can help me getting started with this?
I look forward to getting started
Thanks for all help
Regards
Frank

Where do you want to start? The first thing I sugest you do is get a C/C++ compiler. I hear Microsoft allows one version of Microsoft's Visual Studio to be freely downloaded... try to find if it is true, and if it is then go for it.
Then I would focus on what you will want to do. For interfaces I recommend MFC (because you are into C++, because if you were into C# I would recommend .NET). For checksum algorithms... I suspect you already know what you want the applications to do, right? Checksum algorithms, in C/C++, should come after you are comfortable dealing with memory, pointers, and the like. For that I recommend you read "Teach Yourself C++ in 24 hours". It is a very good book, and it took me 24 hours to read!
Then, at some point, I guess you will want to work with disk files, and serial ports (to send data out of the PC). If this is the case then don't worry, C/C++ and Windows allow very easy access to disk files, and Windows allows easy access to the serial port.
I sugest you come back with specific questions after you get through the first steps: getting a compiler and reading a book (or equivalent web tutorials, if you are not new to programming).
I hope this helps,
Rilhas

Hi Rihas
Thanks for the replay
Yes you are right.. there is a free fully version for 90 days.
And first is problem that you need to find out of the program visual c++.
I have started to look on it and it looks very interresting.
Where did you buy the book?

Hi,
In my application the dialog is set with the background bitmap .I have some buttons in that dialog.Now how can i make the button look flat and should mix with the background of the dialog window i.e,it should not resemble as a button and it should resemble just like a static text.
Thanks in advance,
Radhika.

You need to make button owner drawn.
see this[^]article to get some help.

Hi!
I need to process both ascii and chinese chars to 2 bytes? How do i do that? They are both stored in std::string. Please give an example.
Thanks very much!
|
|
|
|
|
when you say 2 bytes do you mean wchar_t data type? Use the MultiByteToWideChar() function. Although I very often have problems with chinese characters being mapped into two wchar_t characters. Make sure to specify the correct codepage.
|

|
How to specify the correct code page?
|
|
|
|
|
936 = Chinese Simplified
950 = Chinese Traditional
I should also tell you that there are two functions to do this. The one I told you MultiByteToWideChar() takes a codepage, but the second function mbtowc() only takes the strings. I usualy have many probles with the first function, instead of mapping a single character to 1 wchar_t, it instead splits it to 2, which is not unicode. The second function has never failed me. I suggest you try both of them.

about template
i create template class

CTDbList()
{
pCurrent=NULL;
}
void CTInsert(T Value)
{
pCurrent=new CTDbNode(Value);
}
public:
CTDbNode<t> *pCurrent;
};
example
CTDbList<cstring> d;
d.CTInsert(_T("ddd"));

Tick the "Ignore HTML tags in this message" button when you post: none of the the "<" or ">" characters can be seen in you post and it's poorly formatted.

I'm using a CFile to write to a binary file, and I want to modify some text in it. I would like to know if there is another way then rewriting everything after the position of what i want to modify(by modify i mean that it's probably be longer text). I tried the modeReadWrite to rewrite everything after the position, but for an unknow reason it doesent want to read anything(even in shareDenyNone). I even tried to make two CFile objects, one for reading and another one for writing and it still doesn't work. If you have any idea, please let me know.

Has anyone found a way yet to comprehensively parse a CPP Decorated name, to recover the Original Declaration.

That depends entirely on the compiler being used. Here's[^] an article on the name mangling scheme in Visual C++. I don't know how correct it is, but I assume it is. I've seen the mangling scheme before in material published by Microsoft (can't remember where though, sorry!).
