Firstly - stop cross-posting this all over the site.

Secondly - Sounds like you're trying to write some kind of spyware or worse. Actually, I'm rather sure about it. Get lost.

I don't where this should be post really, so this is my fault.
But what I want to write is just one assistant, I still got no reason to write things like you said.
In fact, I know 90% of it already from google or friends.
I just want to know where I can get official and overal topics about these.
MSDN talks some scattered.

In the moment, we have a multiple language software - including English, Chineses simple and trudition, Japanese, French, Korean and more in the future.

We used inno setup before.but it only supports english.

Now I need a unicode installation pack, user can select a language in install process.

Do you know which installation software can do this?

Thanks.

Execution Speed of C++ in different circumstances!!!! [modified]

Hi everyone!!

I have a scientific C++ program which requires a good speed to run.(the program runs a lot of matrix and vector operations)

For doing that, I come across following options on the net:

1. Use of turbo C++
2. Use of Linux instead of window XP

My current system uses Dev C++ over Window XP.

Can I expect some speed increase using above options?
If so, would it be significant?

Thanks

I did read that the Intel compiler creates "best" (here in the meaning of fastest) code on Intel processors, compared to Microsoft's VC and GCC. Never used it myself and I don't have a link to an up-to-date statistics, Wikipedia mentions something about optimizations[^].
However, design and architecture improvements can give more dramatic improvements, e.g. reduce complexity in algorithms, profile for bottlenecks, rewrite for parallel processing on CPUs with multiple cores, outsource matrix operations to GPU... to name some possibilities. Those things are outside the possibilities of a compiler (automated tool) but could be worth to check.

Turbo C++ still exists? Smile | :)

Hope it helps.

I would first suggest using VS2008 compiler (which I believe you're not using) first; then
if you have the time and money, try the Intel compiler, it might be a little bit faster
in some operations, especially ones where the use of specific CPU hardware instruction codes
(SSE, ...)

If your matrix and vector operations work on large scale matrices, I would highly suggest
investing the in the Intel compiler AND the Intel MKL (math kernel library)

Disable esc key exit for MFC Application

Hi experts,

I have an Application in MFC using single dialog window.

Problem i am facing is, it exits when i press escape key.

i want it to exit when i press "Exit" button that i made my self and also by pressing "x"(default close button provided in dialog) button on top right corner of window but not by "esc" key.

I tried emptying the implementation of "OnCancel" function. It solves the problem of "esc" key, but it also disables, exit when i press "x" button.

Please help me, it is very annoying when i accidentally press exit and window goes away.

If possible, tell me way to add, minimize button along with "x"(close) button on the top.

Regards,
Swinder....

Add an OnSysCommand[^] handler that watches for SC_CLOSE and calls __super::OnCancel() when it hits.

Also, one use use PreTranslateMessage to intercept the ESC key. Add the function to the dialog using the class wizard, then check for the ESC key.

BOOL CDxf2NastranDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
	// TODO: Add your specialized code here and/or call the base class<br />
	// ESC key<br />
	if(pMsg->wParam == VK_ESCAPE) { return TRUE; }<br />
<br />
	return CDialog::PreTranslateMessage(pMsg);<br />
}<br />

Did you #include <string>?

Also, basic_istream has a member getline(), maybe try using that one?

Status bar, owner-draw theme background?

Hi, is it possible to draw the background of a status bar with UxTheme.dll? I was browsing through available XP Visual style controls[^], but can't find the status bar background.

Thanks for any help. I looked into existing articles here at CodeProject, which usually derive from CStatusBar (to get the background) and then extend it. I like to find out if it's possible to make an owner-draw control without using the standard status bar control at all.

Cheers!

Can anyone tell me why i receive right data in case of traditional chinese but not in Simplified Chinese... I'm searching and experimenting "How to display right data in GUI" in case of "Simplified Chinese Character", But nothing seems to work..

So i just need to know why my applications(Non Unicode) is able to display right data in GUI in case of traditional chinese, but not in simplified chinese?

P.S
I'm reading data from text files, which are encoded in UNICODE.

Thanks.
