If List::insertNode takes a treeNode* parameter, you probably need to write
l.insertNode( &t ); It isn't clear to me what you're doing.
Normally I wouldn't recommend writing your own list and tree classes; the C++ standard library includes std::list and std::map or std::set for that.

But you have not indicated what specific problem you are having. I'm assuming you have single-stepped through each line of code using the debugger. If not, that would be a good place to start. Simply putting the code together, running the program, and noting the output, does not indicate whether your program is doing the right or wrong thing.
Are items added to the tree as expected? Can you traverse the tree in prefix, infix, and postfix order? Does changing your code to the following help:
void output(treeNode *name, List &l)
{
if (smaller != NULL)
output(smaller, l);
cout << name << endl;
if (bigger != NULL)
output(bigger, l);
}

Yes, that is very similar to what my teacher told me to do, if not identical. I was too much of a bonehead to not write it down though, thinking I could remember a couple simple parameters. I was wrong.
Sorry my thread was so vague. I will try to be more specific next time.
Thank you.

How do programs like window washer accomplish this. Do they go low level or hi level and just zero a file?
Wouldn't it make sense to just encrypt a file with a random password then delete it...?
Just cursious

I heard they overwrite it twice just to make sure any residual magnetism is destroyed.

Ahhh I wondered why they did that...Window washer does it like 30 times....I couldn't figure out why...

Indeed, the default behavior of the shred command on many Unix systems is to overwrite the file 25 times (!!) with random data, with the option of adding a final overwrite with zeros in an attempt to hide the fact that shred was even used.
Note, however, that most programs like shred can only work at the file level -- filesystems which do not guarantee that overwritten bytes are written to the same place on disk will likely leave residual chunks of the data file behind in unallocated space.
Of course, probably the best way to keep that data from being recovered would probably be to overwrite it with random data many time, zero it, delete it, cause a head crash on the occupied sectors, then melt the platters

i wanted to use switch instead of if-else so code:
CString buffer;
m_list.GetText(chosen,buffer); //select from listbox
switch(buffer)
{ case "Wet etch Al H3PO4":
recordset.Find(AFX_DAO_FIRST, "ID = 'AlW1'");
break;
case "Wet etch Al H3PO4/HF":
recordset.Find(AFX_DAO_FIRST, "ID = 'AlW2'");
break;
}
i have error: switch class cstring illegal and case expression not const, how do i correct this?

You can't use strings in a switch statement.

hi..
Iam involved in the migration of an application developed on VisualAge C++ for windows to Visual Studio 6.0.
Could any one give some info of how it is to be approached ?
Any tips, tricks and pitfalls in achieving the objective ?
Any help is greatly appreciated.
Thanx

I have experience with Visual Age C++ (for OS/2) and with Visual Studio. Given that their approach to user interface code is so different, I would suggest re-engineering the UI code from scratch. I wouldn't try to 'port' the Visual Age stuff; it's just too different. Lower level logic could probably be ported, however.
Good luck.

Try modifying the parent window style to include WS_CLIPCHILDREN. If the parent is a FormView, you can do this in the dialog editor; otherwise, override PreCreateWindow.

Hi all,
There are fonts that define characters in the C1 region, namely 0x80 thru 0x9F. (Windows CP1252 does have characters defined in C1 as well.) The problem is that these characters show up as empty square boxes when I use TextOut() and DrawText() to draw characters in these fonts. It appears that TextOut and DrawText filter out these characters. But Notepad2000 can display these characters as any other ASCII characters.
My question is: What character drawing function can display characters in the C1 region? Definitely there must be a way to display them. Otherwise, these characters don't show up in Notepad2000 either.
Thank you very much in advance for your help.

There are no problems displaying any character with TextOut() etc. that I am aware of. If you are seeing square boxes then you aren't using a font that includes the particular characters you want. You can use the Windows Character Map app to see the character sets for all installed fonts.

Thanks for your respose.
FYI, the font does have these characters. It was designed for Windows 3.1 and all characters show up very well. I tested the same font with Notepad2000 and DrawText() and TextOut() on Win2000. Notepad can't display 4 chars at slots 0x80, 0x8e, 0x9e, and 0xb7. But DrawText(), TextOut(), and Character Map app do not show over 25 characters. So I just wonder what API to use, or what parameters to set, to display them. I am working on an application that needs to display all characters available in a font.
Thanks a lot for any insight.

It sounds very strange that Character Map doesn't display these characters. I would focus on the font itself. Maybe it needs to be updated or recreated to work properly with W2K etc.

Hello Everybody,
what is the difference between using AfxMessageBox(" ");
and MessageBox(" ");. Both of them are used to display message only then why two versions.

CWnd::MessageBox will call the MessageBox API using the HWND of the CWnd (the m_hWnd member) as parent window. And can only be used from CWnd derived classes.
AfxMessageBox is an MFC global function and internally call CWinApp::DoMessageBox which calls the MessageBox API and uses the main window of the application as the parent window. AfxMessageBox can be called from anywhere in the MFC program. If you dont have a main window it will use NULL as the parent window
I use CWnd::MessageBox cause it lets you set a title, whereas AfxMessageBox will show the app-name string as the title.

Hi
I'm in the processof converting a VC.net 2002 project to vc.net 2003 and suddenly got and error with this statement
catch (CException &e)
{
TCHAR szMsg[1000];
e.GetErrorMessage(szMsg, 1000);
ShowErrorMessage(szMsg, "CException", MB_OK, _T(""), GetActiveView());
return FALSE;
}
Can anyone tell me what I should change to get this compile with .net 2003 ? (I'ts probably obvious but I've been awake for 28 hours and am getting a bit tired)
/Thomas
