It is worth seeing if you can use one timer to handle several functions, e.g a 0.5sec function could processed on every tenth call to a 0.05sec timer.

As far as i know the only limit is
the CPU performance , as everythimer
thread in an O.S will use some resources
at some excess limit the resources are bound
to be extinct

Yes, timers are a limited global resource.

No global resource is unlimited. To see how much you can create, you should write a program that just creates timers and reports the number of timers created when an error occurs...

CreateEx Creates a Pop-up Window unlike Create

yes WinCreateEx::Create creates not only create child window(what CWnd::Create does)but also pop-up and overlapped window
attach it to CWnd object:->

Hi
I have a dialog based MFC application in which I want to hide mouse globally.
I mean to say when I hide mouse it gets hidden but when i move my mouse over some other application or some other window, it gets displayed.
What I want to do is, once I hide my mouse, no matter where I move it, it should not be shown.....
Or is there any function through which I can disable my mouse ?
Regards

i don't know of a funtion doing this but have you tried
using a global mousehook? are you familiar with window hooks?
i copuld imagine catching WM_SETCURSOR will do this but i'm not sure.
some links:
WM_SETCURSOR
SetWindowsHookEx()
MouseProc()
good luck!

Hi,
I haven't been using stream i/o very often, thought it was simple.
Wanted to read in an xml-file with 0x0A line delimiters.
used a for loop
(vc++ 6.0 on xp pro)
ifstream ifsIn("x1.xml");
string strData
for (string s; ifsIn>>s; strData+=s+'\n') {}
.
Was surprised to see, that operator>> uses blanks as input delimiters.
->Normal or bug?
Hence used
for (string s; ifsIn>>s; strData+=s+ifsIn.peek()) {}
i.e. blanks and newlines reside in stream and can be appended to be preserved in result.
Tried for fun to get '\r' + '\n' from ifsIn instead of just '\n' into my strData, because it's a windows format text file. Used ifstream ifsIn("x1.xml", ios::binary), but no success: Stream was empty then.
->Normal or bug?
I didn't find any way to set a property of the stream like "Use no delimiter, slurp in whole file".
->Is there?
Thanks for your assistance
And best regards
Werner

Sorry, 2nd for-loop is buggy of course, actually it is,
string strData;<br />
ifstream ifsData("x1.xml");<br />
char cPeek[2];<br />
memset(cPeek, 0, sizeof(cPeek));<br />
for (string strTmp; ifsData>>strTmp; ) {<br />
cPeek[0] = ifsData.peek();<br />
strData+=strTmp+cPeek;<br />
}<br />
Regards
Werner

Does the RECYCLER folder always exist as C:\RECYCLER or there is a CSIDL for it that I use to query the recycle bin folder using SHGetFolderPath?
Thanks!

Hello everybody,
When a user is using the Task Manager to End a Process or a task there should be a message sent to the application – anyone knows which message is? Also there is any change to handle the message – e.g. a message loop.
Thank you.

How can I translate the keyboard character to the current keyboard layout string? In the method CWnd::OnKeyDown I would like to translate the input character to the non English character - e.g. German. Maybe it is not possible to do it in the OnKeyDown method and I have use rather another method/mechanism, but I don't know which one. Unfotunately the given method always returns me the English character even I switched the keyboard layout to another language.
Thanks,
Abyss

LoadKeyboardLayaut(_T("00000409"),KLF_ACTIVATE);

Hi,
I didn't know this method, but based on MSDN it loads the keyboard layout. I have to play with this maybe it will automatically translates the character to the local character...
However user can switch to another languages. How can I catch this event? Or will Windows automatically handle this situation? It only requires to have the keyboard layout loaded to the application?
Thanks for your help,
Abyss

Hi,
I am developing an application with several components in it. The main application will have a GUI and there are several components like BHO, MS Office Addins, Clipboard trackers etc. I have a problem here.
These components should communicate with the main application by some means. It has to pass some events or some values to the main application. I will be creating both the components and the main application and I would like to know, the best method to connect the components to the main application.
I have pretty good exposure to COM and Windows programming.
Also Is it possible to create a Singleton Automation server ?
Thanks and Regards
