Yep, the file is in the same directory as the project. This is bad.
It occured when I click Save. I closed the workspace, reopened it then the cpp file is gone 
I even looked for it in the project dir and its not there anymore (I kept the project directory window open, and it was still there until I refreshed it after I saved the project)
EDIT:
After a few minutes of searching, I found one with situation similar to mine:

If you are referring to VC 7.0 (or maybe even 7.1?), this is a known "problem". For more info/verifications, you could google some MS newsgroups (usenet news).
Obviously it can be fixed - but only by the ones destroying your data in the first place.

yes, it has happend to me many times, after saving the file i try to compile the project, the compiler complains that the file is missing.
I know this behaviour so i just do a save all again and then compile again.
yes,
in the past i have lost a file like this, but lucky that i use VSS.

I noticed that if I add a normal ComboBox to a dialog (dropdown list) and add some strings, even though the strings are added (I verified that), the list isn´t displayed when i push the down button. Can anyone give me a solution to that?

Did you remember to resize the dropdown in the dialog editor?

You need to be more specific about what you're trying to do and where you're running into problems. From your questions, I can't tell if you're having problems with OLE drag & drop, or copying files/folders, or ...

Do you want to move or copy files with the copying dialog of the windows explorer?
If so, then have a look at SHFileOperation.
Don't try it, just do it! 
|
|
|
|
|
for example, there are dozens of files and file folders(which also include files) under dir_A\sub_dirA, now I want to copy and paste all the files and file folders under dir_A\sub_dirA into the dir_B\sub_dirB, I just don't know how to do it.

|
|
SHFileOperation... it's the API what windows explorer uses when copying, moving, deleting, ... files.
Don't try it, just do it!

hi,
i don't really understand your question.
what are you trying to define ?
why do you need to define things such as Language, Tools, OS, etc... ?
i'll try to give a small anwser here, but i fear to be "out of range"...
Language : something you use to write some code. a language has special rules that must be respected like the grammar, the syntax...
OS : an operating system is a "big" software that permits to the users of a PC not to care about the hardware. if provides layers (APIs) and functionalities like a GUI (or not - console modes).
Package : I don't understand your request... a package is a set of things... it depends on the context we use this word...
DTP, RAD : i don't know what these are

Are you asking for explanations of tools, OS, Languages?
Micorsoft visual source safe is a tool that is used for backup purpose. winzip is a tool used for zipping purpose.
A package like software that is used for particualar purpose is called as tool.
A langauage is a software used to develop any kind of applications.
An Operating system,is a "big" software that permits to the users of a PC not to care about the hardware. if provides layers (APIs) and functionalities like a GUI (or not - console modes. (From -TOXCCT >>> GEII power)
A packages is a software developed by a language run in an OS.
Desk top publishing also known as DTP used for desinging purposes. Some packages like Adobe photoshop, coredraw, pagemaker, used for designing purposes.

Hello -
I read through a Samm's book... I read through Petzold.. and I still don't have a handle on this.
I am writing software to analyze a bunch of data with the data organized in columns. The general plan is to use the dialog model and open a sub-dialog for each column of data.
No problems creating sub-dialogs. It's destroying them that is confusing me.
Say that I setup, create, and activate a dialog using Create() and ShowWindow().
Now comes time to destroy the window.
I see a variety of ways of doing this:
1. The sub-dialog (an MFC-derived class) executes this->Destroy(). This seems wrong as a class is deleting itself without notifying the parent class.
2. A call-back function destroys the class. This seems reasonable.. except that the child calling the call-back that is part of the parent class winds up calling the child's Destroy() and control eventually returns to a destroyed class. Which ruins the idea.
Somewhere in the MFC documentation, it says that calling a sub-dialog's Destroy() function deletes the window.. but that the class's must be deleted to destroy the underlying data structures.
By this point my eyes are crossing.. and I could use a tip.
Regards,
Mark

I do not know if this can is you of aid, but I in my application create one in this way ProgressBar Dialog:
...other code...
m_pDlgProgressBar = new CDlgProgressBar();
if(m_pDlgProgressBar != NULL)
{
BOOL ret = m_pDlgProgressBar->Create(IDD_DLG_PROGRESS_BAR,this);
if(!ret)
AfxMessageBox("Error Creating DlgProgressBar");
m_pDlgProgressBar->ShowWindow(SW_SHOW);
}
else{
AfxMessageBox("Error Creating Dialog Object");
}
....other code....
In order to destroy the dialog I have override PostNcDestroy Function
like this:
void CDlgProgressBar::PostNcDestroy()
{
delete(this);
SECBitmapDialog::PostNcDestroy();
}
it makes to know me...
Excuse but my English is not of the best ones 
Too many plans make the health badly...

What is the std::string equivalent for the following CString operation?
CString time;
int minutes = 5;
int seconds = 5;
time.Format( "Time is %02d:%02d", minutes, seconds );
Output : Time is 05:05
