1) CString stores the length of the string before the string, so for the string "Hello", it would store a byte with the value 5, and then the actual string data. This is documented in the CString/CArchive documentation (sorry, I can't remember which one).
2) They're called templates. There is plenty of information about templates on CP. Have a look at some of the articles. Basically, they let you customize a class without having to rewrite it, eg. You could have a CList<cstring,cstring> or CList<int,int> without having to write two different classes. Again, have a look at the articles for a more in-depth discussion of templates.
Hope this helps

I'm writing a program that will search for files. So I let the user pick the starting drive or path and the file name (the file name can have a wild card in it) example path = c:\ filename = doc.t*. I string them together and pass this to the findfirstfile api. If nothing matches the filename then it errors out with and invalid handle. So how do I make it go to the next directory under that path to find the file? Or how do I make it keep searching for the file until it finds it and returns the path to me?
Thanks

I'm not looking for a class that I can include into my program. I just wanted to know how it's done.
Thanks

You need to get the list of subdirs in the current dir, then recursively call your function (which ends up searching for
files and subdirs). Functions like these usually have signatures
of the type:
void findFiles
(CString strWildcard,
CStringArray& listOfLocatedFiles,
bool bRecurse)

Hello
I have figured out how tome make the changes to the SPDemo program on this site. http://www.codeproject.com/splitter/SimpleDlgSplitter.asp
However, when I went into the ResourceView tab and clicked on Dialog I wanted to remove one of the three windows. I deleted the top right window and it complied fine. But when I try to run it I get this error.
"Debug Assertion Failed"
"Program: ...\Microsoft Visual Studio\My Projects\SPDemo\Debug\SPDemo.exe"
"File: dlgdata.cpp"
"Line: 43"
This file is part of the MFC library and that line in that file is "ASSERT(FALSE)"
What does this mean and how can I fix it?
Thanks
Scott

Hi
Here is my problem.
I am programming in Win32. I create a window that contains a treeview window child :
hTV = CreateWindow(
WC_TREEVIEW,
NULL,
WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | WS_CAPTION |
TVS_HASBUTTONS | TVS_HASLINES | TVS_LINESATROOT | TVS_EDITLABELS ,
rect.left,rect.top,rect.right/4,rect.bottom/2,
hwnd, // parent window
NULL,
(HINSTANCE) GetWindowLong(hwnd, GWL_HINSTANCE),
NULL);
It works well except that instead of having the whole background of the treeview as white (which is I think the default color), the background of the "decoration" stuff (lines at root, lines, buttons) of the treeview is gray.
I would like to have it all white.
Would someone know how to do that ?
Thanks in advance for help
Ben.

I have to develop an application having a not easy
User Interface.
I have to show serveral panels in the MainFrame
(not at the same time) and I have to change the
MainFrame structure according to the panel shown inside
it (in some cases I have to show and manage a splitter,
in other cases I need the whole MainFrame).
How can I solve this problem ?
I've tried to create a MDI application and I have
registered some tamplates as shown in the following
code.
AddDocTemplate(new CMultiDocTemplate(
IDR_LANGUATYPE,
RUNTIME_CLASS(CLanguageProblemsDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CLanguageProblemsView)));
// Form Rilevamento dati
AddDocTemplate(new CMultiDocTemplate(
IDR_RILEVAM_DATI,
RUNTIME_CLASS(CLanguageProblemsDoc),
RUNTIME_CLASS(CSplitterFrame),
RUNTIME_CLASS(CRilevamentoDatiView)));
I have made this choice in order to have different
templates to create and show when I want.
(I'm not sure that this is the rigth way to solve my problem).
Now the problem is that I don't know how to select the
appropriate template to create and I don't known how
to switch from a document to the other one (all by code).
Can someone help me ??
Thanks a lot !!!

When I exit the modal dialog should I call EndDialog(IDOK) or CDialog::OnOK(). From what I am understanding either is fine....
It seems that with neither call is the modal window destroyed. Is this a bad thing? Because in the CP modeless article I see that they destroyWindow a modeless dialog> Why dont we need to destroyWindow a modal dialog?
Appreciate your help,

In DLGCORE.CPP u can find in the implementation of DoModal
// destroy modal window
DestroyWindow();
PostModal();
MSDN says for EndDialog "it sets a flag and allows the dialog box procedure to return control to the system. The system checks the flag before attempting to retrieve the next message from the application queue. If the flag is set, the system ends the message loop, destroys the dialog box"

Thank you. Its so odd.if I do google on EndDialog it takes mt to a more informative microsoft site than just searching in help in the dev environment....
The info you gave me wasnt in my local msdn help...
Appreciate your help,

That is misleading because MFC creates all dialogs as modeless and manually disables/enables the dialog's parent as appropriate.

Hi!
I have problems with method SetOptions.
When I call SetOptions(ECOOP_OR, ECO_SAVESEL ) and CRichEditCtrl has no text some styles for this controls simply are disappearing (like ES_AUTOVSCROLL).
But when I type some text everything is OK.
Any help?

I have numerous word documents that I need to email to several different people. The first line in the word document contains the email address that the document is supposed to be sent to.
Is there any way that I can take this document and parse it so that I can get this information and then send an email to the address that was taken out of it?

Solutions depend on your design and tools. For example, what socket tool do you want to implement, i.e. pure winsock or MFC's CSocket? Deside on a socket design and then we move from there.

Actually I want to attach this email code with a code I am already using for sniffing packets. In that I am using raw sockets of Winsock api. But I feel that MFC's CSocket would be a better chice to be used.
Plz provide me further info. on it and plz keep in mind that I am a beginner and does not have much knowledge in VC++. So kindly try to suggest me the easiest ways of doing so.
