Other people can answer you better than me.
But I noticed that you "get the value of the variable. Instead I get the variable declaration information.
" when the variable is nto valid at that moment, like a NULL pointer.
For the second, look for the edit and continue compiler option and look also for the conditions when this is disabled.

I've been on the project that using CSocket to send file from client to server. When i test the program, only part of data send through CSocket(about one third of the original data). I use CSocket as a SOCK_STREAM. Can anyone figure out the problem on my code?
thnx

Hi,
Why dont u try using out an acknowledgement mechanism. That is whenever the client is sending data to the server, the server should send acknowledgement for the data. In case the client does not receive the acknowledgement for a certain period of time, then the client resends the same data.
Let me know if this helps you.
Regards,
Mahadevan.

i tried to send 34kb through one send() function and only 8kb go through.
Another way around it is to divide the file to several small chunks of 8kb.
But i got stuck there. Could anyone give me idea how to do it

A call to Send() might not send all the data you gave it.

I've written an ISO 9660 burner application, which works, but after I burn a disk I need to eject and reinsert the disk before windows sees the new files. How do I tell windows to reload the filesystem?
I've found SHChangeNotify which seems like what I should use, but no combonation of option does anything that I can see.
SHChagneNotify(SHCNE_ALLEVENTS,SHCNF_PATH,zdDrive,NULL);
seems like it should be overkill but it doens't work. Lesser options don't work. In particular sending media removed then media inserted didn't work. Nor did various updateItem combonations.
Am I on the wrong track? Are there other options I should give?
I also send a message to explorer, which seems like it might be working (the window closes when I send a media removed), but the contents don't change when I look. Nor does a dir at the command prompt get anything.

Very cool!  Any chance of turning the CD burning part into a CP article? Thanks in advance!

I don't think my boss would agree to sharing our source code, which makes an artical less interesting. Although we did agree that we should write a book on how to do this.
Writing a CD is easy enough, but keeping track of each different option for each different media can be a pain (CD-R, CD-RW which might be MRW formatted, DVD-R, DVD-RW either sequential recording or restricted overright, DVD-RAM, DVD+R, and DVD+RW) There is no model that is common between all of the above. I did not use all the possible modes, so I'm not sure how to use them all.
If you think there is a useful artical here I'll write it (but no source code will be included!)

Did you notice that some applications like yours they eject the CD when they are finished ?
And then they close the tray again ?
Like Nero.
Maybe because of the same problem you have.
And most of applications playing music ( even Windows Media Player and NeroMix ) have the same problem. They have problems to automatically update their music list once he CD is inserted. It doens';t always work.

Hi!
I want to display multiline text in the edit box. I use CString as a member variable. In edit box properties I checked Multiline. The text is from dialog based application and it consist of data. I would like to display each data in new line but when I use Format with “\n” I don’t get new line instead I get small black rectangle character. After the small rectangle there’s no new line. So what I should do to get new line displayed?
Thanks in advance.

Use \r\n instead.

Thanks a lot it works great!!!

what's the format with "\r" process?
msn:Flashcutreg@hotmail.com
|
|
|
|
|
Format with "\r" stands for "carriage return" which is an escape sequence.
|
|
|
|

As a rule of thumb (there are some variations to this rule - like with message boxes in Windows), when it comes to text just remember this...
\n - Unix/Linux/MacOS X/etc.
\r\n - Windows/DOS
\r - MacOS 1-9

hello,
I am new to MFC programming. I have an urgent requirement of
creating an Address Book application with MSAccess database. I am using the
ODBC data source administrator.
I have created the GUI with two fields for name and address.
For this Edit box i have created the member variables also.
I am able to retrieve the data from the database through DoDataExchange part.
For Adding a record into the database i have written the
following code.
void CAddbookView::OnAddClick()
{
m_pSet->AddNew();
UpdateData(FALSE);
}
In this case the data i am entering is overwriting the current data. And
the next, previous, first and last control in the DR_MAINFRAME main form are
disabled.
So i want to know whether i should add any extra code for the
add operation or any steps needs to be done while creating the GUI.
I am stuck with this problem. I need to do update also. I am totally
lost in the code.
If anybody can help regarding this it will be of useful and timely help.
Thank you

You need something like:
void CAddbookView::OnAddClick()
{
CString strName,
strAddr;
m_name.GetWindowText(strName);
m_addr.GetWindowText(strAddr);
m_pSet->AddNew();
m_pSet->name = strName;
m_pSet->addr = strAddr;
m_pSet->Update();
}Make sense?

Hello,
Thanks for your message. Sorry that i could'nt reply immediately. I tried
the same code in my application. Then i found that there is a problem.
I am using ODBC to connect to access database. So the member function like GetWindowText() is not available. I am not able to use the above code
u had sent.
I think for ODBC the coding part will be different. I am not able
to find the related member function available in that. So still i am having
the same problem.
Thanks in advance.

And that problem would be what, exactly?

ODBC (which is a way of connecting with a database) and the GetWindowText() method (which gets the text/caption of a control) are mutually exclusive things. One is in no way related to the other.

Why?
skgk wrote:

Naturally, but since I know nothing of your project (other than it has a class named CAddbookView, a method named OnAddClick(), and a member variable named m_pSet), I obviously couldn't make it an exact fit. Yes, you might have to tweak it.

Which member function?

Hey all.
I have a static text control on my dialog application. I set the text at startup with SetDlgItemText(IDC_STATIC,"Blah Blah"); It works great, however if I lose focus (ie, minimize the window, or even switch to another window and back) it disappears. Does anyone know of a way to get around this?
TIA

Is the static text control covered by another? (You can check this in the resource editor).

Hi Ravi:
Nope, there's only one static control on the whole page, and it's off to the side not near anything else
