You laugh ... but sadly, I've seen people try to make 20-dimensional arrays and wonder why they get compiler errors ... not to mention logic errors :P

I really like your sig!

It's the first.
My reasoning: a pointer is a variable that stores an address, which is always 32 bit in a 32-bit OS, regardless of what type of instance it points to.

You listed 3 types:
char
ptr to char
ptr to ptr
They are not the same.
In the case of a pointer, it matters what type it points to in case you want to do arithmetic on the pointer value, such as incrementing it for example.
C++ allows any number of levels of indirection.

Hello there.
Does anybody know how to hide or don't show the child window caption in the "Windows" menu of its Client Window?
I don't want the "Windows" menu of a Client window show some of its childs windows captions.
Thanks.

Did you Mean :-
FWS_ADDTOTITLE
or the one in the window Menu of the parent frame then the application calls CWnd::DrawMenuBar you can choose here wether you need to add the menu.

Thank you for your answer.
I meant:
I have an MDI App.
Anytime the App creates a child window, the caption (title of the child window) is showed by the menu "Window" of the frame (the client).
Ex:
The App creates (in this order) 2 childs windows whose titles (captions) are "Document A" and "Document B"
Then, the "Window" menu of the frame window (the client) is showed as fallow:
Window
--Cascade
--Tile horizontal
--Tile vertical
--Arrange icons
...........
1 Document A
2 Document B
The problem is that I don't want the "Window" menu of the frame window show the titles of the child windows created.
If you could help me with this...thank you very much.
John.

It is equivelent to
ObjectRoot::ms_instances[ ObjectRoot::ms_numInstances ] = this;
ObjectRoot::ms_numInstances++;
Good to see you are hooked up with HLA stuff. Hope you enjoy it

1) It returns the current value of ObjectRoot::ms_numInstances (which is a static integer representing the number of current instances the array has pointers for).
2) It sets the last unset element in the array (that is the first NULL array element -- represented by ObjectRoot::ms_instances[ObjectRoot::ms_numInstances]) to the value of the current object.
3) ObjectRoot::ms_numInstances is incremented by 1 (set to the next NULL value in the array).

Can you tell me the function to convert ansi string to utf-8 string?
|
|
|
|
|
Have you tried MultiByteToWideChar() or WideCharToMultiByte()?

If no other solutions, I think you can try successive calls of MultiByteToWideChar and WideCharToMultiByte. First call converts the ANSI string to Unicode format, and then the second call converts to UTF-8 format:
char ansi[] = "Ansi String";
wchar_t unicode[100];
char utf8[100];
MultiByteToWideChar(CP_ACP, 0, ansi, -1, unicode, 100);
WideCharToMultiByte(CP_UTF8, 0, unicode, -1, utf8, 100, NULL, NULL);
Hope it works.

Hello there,
again i need some help. I have to write an application to get several information from the MSN Messenger. I've used the IMessengerApp / IMessengerIMWindows and several other classes. It works well, but now I've recognised that it only works with msmsg.exe and not with msnmsgr.exe.
But about msnmsgr.exe i don't find anything (Typelibs, Application-Ids and so on)
Does anyone know how to retrieve information like current user or online state ?
Would be great if someone could help me
thanks

A lot of the MSN IM features that used to be accessible thru automation were removed a few versions ago (for security reasons, probably)

I use the following to Open a file on an FTP server. Below is used . Now after i use OpenFile, is there a way to play the file without storing it to disk. I would like to just have the video played without having to store to disk and then use something like ShellExecute to play. Cause now i will have to be concerned about deleting the file. I only have an FTP server to work with. Is there a way to maybe save in memory and execute from memory using some know API?
CString filenam = "0015.avi";
m_pFtpConnection = m_Session.GetFtpConnection (ftpServer,userName, password, port, TRUE);
CInternetFile* pfRemoteFile=m_pFtpConnection->OpenFile( filenam, GENERIC_READ, FTP_TRANSFER_TYPE_BINARY, 1 );

I guess what i am attempting to replicate is when you attempt to play a video clip from some sites you get the option to open and play or save to disk. I would just like to automatically open and play without having to save to disk...

Are you sure that "automatically open and play" is not just saving to some temporary file and deleting it when done?

Well, i tested this by using an app that i found. There is a Get File button that uses a progress bar to seemingly download the file. I searched the drive for the file and could not find it. Then i selected "play video" and it played. So it is from what i can tell being saved in memory and not to disk. Personally i would just use a web server , but for security reasons i am limited to an FTP server so there is a bit of maintainance involved.

Searched for the name of the .avi... I think it was called like
0015.avi. I knew the name cause when i selected it to open, the filename name displayed on the top of the little dialog.
