Hello comunity,
how to determine from which class is an dialog object derived?
So, i wand to copy data in to clipboard, but how to know which methods to use,
for example, if i have an CListCtrl a can use pListCtrl->GetItemText(iIndex, iSubItem);
to read text and copy them to clipborad, but how to know the base class when i want to copy from
CEdit field??
Is there any method or macro to use for this?
regards

dialog controls, you mean to say I think.
What about CObject::IsKindOf

typeid( type-id )
The typeid operator allows the type of an object to be determined at run time.
Somethings seem HARD to do, until we know how to do them.

"but how to know the base class when i want to copy from

What is the need for knowing base class to get the data from CEdit field ?
Why you not using GetWindow text ?

What when nomeone want to copy from CListCtrl? GetWindowText give me only the caption, not the item text!
i try with
<br />
CRuntimeClass* cRuntime = NULL;<br />
CWnd* pWnd = this->GetMainWnd()->GetFocus();<br />
<br />
cRuntime = pWnd->GetRuntimeClass();<br />
if("CSortListCtrl" == cRuntime->m_lpszClassName)<br />
{<br />
<br />
pList = (CSortListCtrl*) pWnd;<br />
<br />
csData = pList->GetItemText(pList->GetSelectionMark(), 1);<br />
<br />
}<br />
else if("CButton")<br />
{<br />
pWnd->GetWindowText(csData);<br />
}<br />
else if(..)<br />
else<br />
...<br />
that is my problem...

ok, now i change the - to 0, to try to explain this example more clear, this file will be print out in txt format, require the c++ to read from the txt file and also, it is the birnary format, and now can see that
the void V is the whole among the group of 1,
1111
1 11
1111
the two exceptional 1 E is locate at:
00001
00000
00010
which consider at not inside the group of 1
and like this
111
111
111
will consider as a group of 1
and so S = (A-E)/(A+V)
is this help to explain the problem? thanks
sorry to have to post this question again?

have you considered ask this in the Mathematic forum ?

I think you asked this question yesterday is it homework?

Are you able to solve this problem on paper? Remember that a computer can't do anything you didn't tell it to do. If a 'space' surrounded by 1s means something, that can easily be searched for. If a series of four (or five) 0s is special, that too can be searched for. Work this out on paper and the code will (almost) fall into place.

How is this important (to the problem)?
sinbear wrote: ...it is the birnary format...
Which means what exactly?

This is all but meaningless. Please clarify.

What is a "group of 1?"
Plenty of questions have been asked of you but I've yet to see you respond with any clarification. People are willing to help, but only if you can present them with a good understanding of what you want.

I would like to check whether the file exists before reading it, however the ios::good flag and ios::bad do not seem to flag the expected values and the program is crashing...
bool CSentenceList::readFile(const char strFileToRead[MAX_FILENAME_LENGTH + 1])
{
char strLine[MAX_SENTENCE_LENGTH];
fstream fileToRead(strFileToRead,ios::in);
if (ios::good != false) // what does this check?
{while (!fileToRead.eof() && Size < MAX_LINES)
{ fileToRead.getline(strLine, MAX_SENTENCE_LENGTH);
if (strlen(strLine) > 0)
{ Sentences.push_back(strLine);
Size++;
}
}
return true;
}
else
{ throw "File cannot be read!";
return false;
}
fileToRead.close();
}

ios::good is always "good".
You need to check "if(fileToRead)" at that point.
Cheers,

strFileToRead holds a valid value at that point, the problem seems to be that ios::good validates to 'true', even though the file does not exist for example. This problem only happened with this program (one-off), so I was wondering what was wrong with the code.

Hi,
tks for the response for my query.
However, the link u provided me, i have tried before.
It only subclass the client area of the Main Frame. And I can detect mouse clicks from the main frame but not the child window.
i.e. when i use "FILE -> OPEN -> "powerpoint.ppt " ( child window ), when i tried to detect the mouse clicks in this child window (MDIChildWnd), it does not detect at all.
Do you have any idea? I search through all sources and i could not find any solutions.
awaiting for your reply.
Thanks

Hello,
I use Visual C++ 7.1 on the base of Visual Studio .NET 2003 SP1 on Windows XP.
I want to launch a script as pre-build step which call SubWCRev.exe from TortoiseSVN. I surprisingly noted that this program can not be called because its path is not found. I checked the PATH environment variable: C:\Programme\TortoiseSVN\bin is in it, and SubWCRev can be executed from the console window. I executed path > toto.txt in the pre-build command line and noted that the result is false: the path of TortoiseSVN is not there and a path removed yesterday (several reboots in between) is still present!
I already posted another manifestation of this problem: System PATH not recognised in pre-build step?
Does anyone have an explanation?
Is there a way to fix that problem?
Thanks in advance for your light!

Hi all,
I am working on an e-mail client application
I've planned to store every email as *.eml file in the user's appropriate folder (physically created folder like Inbox, Sent Items etc) in HDD
and keeps an *.MDB (CDaodatabase) with fields like
folder, from, to, subject, emlfilepath, emlfilename
So I can query the DB for fast retrieval and when user click/select a mail than open
the eml file and show the mail content on the preview pane
Is this a right way for the e-mail client storage OR any suggestions appreciated

Your idea is not very secure. Keeping emails on the HD like that leaves them wide open for people to read. I suggest you implement some sort of encryption. Also, as a user, I would not like individual emails to be stored in this way (even if they are encrypted). It shows people how many emails I have, and roughly when I recieved them, again not very secure.
What I would like though, an encrypted container. Take a look at 'Jetico Bestcrypt'; or a form of password protect filesystem. Either of these would make it easy for you to store .eml files, and keep it secure.
