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.

What file did you search for?

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.
|
|
|
|
|
I guess i can just download to disk... Use it, then delete when done. For now, that sounds like the only option that i have.

You might want to run Filemon or Handle while the file is being played just to be sure you have the name right. The 0015.avi might be the name on the FTP server, but was given a temporary name while being played. Just a guess...

Have you somehow told the printer to print from a manual source rather than an actual tray? What does the call to OpenPrinter() look like?

Hello everybody,
I have to write a program that generates some scripts that execute something in case of certain events.
The program must provide a visual interface from wich the user can pick available events and possible actions. The script language is not specified so I'm thinking of generating logicals relations between events and actions, like:
If Event1 AND Event2 OR Event3... Then Action1 AND Action2 AND...
From theese relations a specialized module would generate the script.
I need a way of expressing this kind of logical expressions. I don't want to reinvent the wheel  so I would want to use an existing language. I also need the possibility to express time, for example a timeout can be considered an event or an action can be executed for a certain amount of time.
Any ideeas?
Thanks,
Marius

I think what you need is to show the tooltips on the controls of the dialog?
Right?
Use CToolTipCtrl.
Somethings seem HARD to do, until we know how to do them.

Not entirely. The "balloon" message is displayed regardless of the mouse's position. It is displayed only when the password control has focus.

Adding tooltip is simple. Just google for it...
OnFocusing the edit box get the key state using GetKeyState(VK_CAPITAL).
The retun value will be 1 if CAPSLOCK is on see detailed return values below.
. If the high-order bit is 1, the key is down; otherwise, it is up.
. If the low-order bit is 1, the key is toggled. A key, such as the CAPS LOCK key, is toggled if it is turned on. The key is off and untoggled if the low-order bit is 0. A toggle key's indicator light (if any) on the keyboard will be on when the key is toggled, and off when the key is untoggled.
