Probably seek to the end and get the position. that would be the size.

After I posted, it occured to me: I'm opening an ofstream because I only want to write, and so I need to write before I have a position, but if I open an fstream, I can probably do a read to get that info without writing anything....
thanks.

Just out of curisoity why do you need the file length when you are writing to it? Do you want to append? In that case ios::app would be good enough (But I don't think that you would miss that).

Nope - what I want is to know when the file hits 10k so I can archive it and start a new one.

Open the file, call tellg, go to the end of the file with seekg(0,ios::end), call tellg again and calculate the difference.

Hi All,
I've got a CFormView derived view that I need to be able to add some fancy edit controls to at run time. Based on some input from the user, I will have what's essentially a set of edit controls inside a group frame, with anywhere from say 1 to n edit controls, but I won't know how many until runtime.
So, I was guessing this might involve calling CreateWindow directly, but not too sure. The edit controls are actually edit derived ActiveX controls, that do some additional stuff on top of the basic edit control stuff. I remember seeing some sample somewhere for something like this, and it seems like you called CreateWindow and pass in the progid of the control somewhere, but I can't remember the details.
Anyone done something similar?
Thanks,
Aaron

Typically, you'll have an array of pointers to CYourEdits. After constructing this array with something like:
m_array=new CYourEdit*[m_nControls];
for(size_t n=0;n<m_nControls;++n)m_array[n]=new CYourEdit(); you'll have to create each of the controls. The actual creation method depends on the type of the controls, but chances are you have to pass the parent window, the rectangle the control is enclosed in and a control identifier (use 0xFFFF.)

How do copy a CString to a BSTR and vice versa?
|
|
|
|
|
comutils.h ( from memory ) is an include that defines _bstr_t, which internally converts between the two formats. It has a copy() method to return a new BSTR, the one it wraps is deleted in the destructor.
CString s = "22tgsdfdsa5rwer";
BSTR b = _bstr_t(s.GetBuffer()).copy();
CString a = _bstr_t(b);

CString str = "Test";
BSTR bstr = str.AllocSystString();
CString str1(bstr);

I would like to have my program look into a directory and return back all the filenames within it. Does anyone know what the class and function call does this?
Thanks!

FindNextFile API function or CFindFile MFC class.
Like it or not, I'm right.

How does the .clw file look like. You can edit it and restore it.Otherwise delete the .clw file and press Ctrl+W in the resource editor screen. This would restore the clw file

First off, I am using VS.NET. I have a dialog application which will compile fine in debug mode, however it does not compile in release mode. When I compile it in release mode I get the following error:
D:\Program Files\Microsoft Visual Studio .NET\Vc7\atlmfc\include\afxwin2.inl(1034): error C2039: 'Enable3dControls' : is not a member of 'CWinApp'
I know that in VS7 the Enable3dControls function has been deprecated and doesn't need to be called.. and it isn't anywhere in my dialog application either. For some reason it's not passing the assert on line 1034.
Has anybody seen this before? Any ideas on what I need to include, define, etc. to make it go away?
Thanks in advance,

In my CString variable, a "&" character can be in it. When it is displayed in a messagebox or in a dialog in converts the "&" to underline the next character. Is there a way to turn this feature off so it displays the "&" as an "&"???

Select the "No prefix" style of the offending control static text control. This will cause ampersands to be displayed normally, instead of underscoring the following character.

I want to display a dialog as a modeless one. And my code is:
CMyDialog *pDlg;
pDlg = new CMyDialog();
if ( pDlg != NULL )
if ( pDlg->Create(IDD_DLG_MY, this) )
pDlg->ShowWindow(SW_SHOW);
but where should I delete the pDlg? If I don't delete it, it causes memory leak.
Thank you very much!

make pDlg a member variable of the class that creates it. then delete pDlg in the destructor for the owning class.

After you have destroyed the window. Or not using it anymore i would think...
