The rule for public inheritance is simple:
private data/methods are not accessible to B
protected data/methods remain protected in B
public data/methods remain public in B
So you can't change intPriA directly from B methods because intPriA is private.

Hi ALL
I have one problem need you help , I want to save a html file as below
<br />
CString filename="c://test.html";<br />
CStringarray array;<br />
CFile file; <br />
if(file.Open(filename,CFile::modeCreate|CFile::modeWrite)==0)<br />
{<br />
AfxMessageBox("Error happen from opening file",MB_OK,0);<br />
return false;<br />
}<br />
CArchive html(&file,CArchive::store);<br />
<br />
array.Add("<HTML><HEAD><TITLE>");<br />
array.Add("test.html");<br />
array.Add("Report </TITLE></HEAD>"); <br />
<br />
array.Add("<BODY BGCOLOR=Silver>");<br />
array.Add("</BODY>");<br />
<br />
for(int i=0;i<array.GetSize();i++)<br />
{<br />
if(html.IsStoring()) html << array[i];<br />
} <br />
html.Close();<br />
file.Close();<br />
When I open html file , it is as blow:
<br />
<HTML><HEAD><TITLE>test.html</TITLE></HEAD><BODY BGCOLOR=Silver>M</BODY><br />
^ ^ ^ ^<br />
It added some abnormal word that I don't want.

Thank you!!

That happens because you're not writing an HTML file, you're writing a CArchive object. Those extra characters are data inside the CArchive. To write a plain text file, you can use CStdioFile.

Is it possible to create a console application to send an image to the clipboard using:-
c:\image.jpg (for example)
as part of the command line parameter. I have just started learning C++ and am trying to create some simple console apps to get started.
Regards
Paul

Yes... read the image file (look for hints and code in the forum and articles) and then use ::SetClipboardData() (look it up in MSDN ... there is also an example there.). Hope this helps.

Thanks for the reply
Can anyone tell me which header file I have to include to use the clipboard functions.
Is it hust windows.h ?

They are in winuser.h which you get by including windows.h.

The easiest way to find out what header/lib to use, look up the function in MSDN and at the bottom you'll find function information. Hope this helps.

Why does all Username // Password things say to use Solution Explore? What the hell is it? And where can i find it?
According to MSDN its in Visual Studio... Can i access it in Microsoft Visual C++ 6.0 Compiler? How?... will it do any good with logging onto//creating accounts on a server or is it just based on the users comp?

Hi,
I want to calculate the used disk space for a particular folder or the given path. In my knowledge two API's avilable in VC++.
1. GetDiskFreeSpaceEx
2. using LPWIN32_FIND_DATA (FindFirstFile, FindNextFile)
if we use GetDiskFreeSpaceEx, it gives the root directory space only.
Suppose i want to calculate the used space in F:\xx\yy\zz means i have to use
recursive search for all the subfolders using FindFirstFile, FindNextFile and calculate the used space using LPWIN32_FIND_DATA structure. It takes more time.
Is there any other option avilable to get the directory space immediately.
Like Any Folder -> Right click -> Properties --- The windows give quick result. Windows also using some searching concept but they done quickly, I think they updated the information every time somewhere it may be registry or Shell.
Is anybody having any idea about ... plz write...........
Your valuable suggestions are always welcome ......
Regards,
inbha.

make the magic wand tool of photoshop using visual C++ for my bachelor degree,I am a beginner,
any good ideas?thanks a lot
|
|
|
|

LOOOOOOL, that is really a good joke!!! 
Do you really expect us to write the software for your degree?
That is your homework, if you can't handle it, you will fail.
Don't try it, just do it! 
|
|
|
|
|
no,I just ask for some suggestions
|
|

You have to learn BITMAP before proceeding to Magic Wand Tool!.
Actually after Learning BITMAP headers/ColorPalette etc, you could handle each pixel of image, which is starting point for you magic wand tool. it's little tough!!

Your BACHELOR degree, and you're a BEGINNER ? That restores my faith in the future.
As has been said, if you can't do your own work, you don't deserve your degree.

bachelor degree and a beginner,that's not so funny,as I major in optics,not computer science

OK - in that case, one has to ask why you've been asked to write a magic wand tool in C++.
As I understand it, the magic wand is useless by itself ( according to the explanation I've just been given ), it marks an area on which other filters are applied. If I was going to impliment a magic wand, I reckon I'd make a mask bitmap, make it all white, and make the area that is drawn on the main image a black area on the bitmap. Then whatever filters, etc. I applied, I'd iterate through the rectangle that the bounds of that drawn area was contained in, and check for black pixels before processing pixels on the main image.

good idea!but it is only suitable for monochrom image.I reckon I could make the selection according to the RBG value of each pixel.the problem is how to make the scroll boundary indicating the selection.

No, it's not. The MASK is 1 bit, the image doesn't have to be.

I'm not sure what you mean ? To draw the selected area ? You build a path object as you drag the mouse and then draw it.

Yeah, that's what I meant as well 
The only way to know where the boundary is, is to store the mouse position, every time the mouse moves during selection. If you store those values into an array, there are methods you can call in order to turn those points into a line, which is exactly what you need.
