Good summary.
As you mention, the fast code option can can cause a cache miss. Additionally, earlier versions at least, could result in enough bloat to create extra pages. Related code, that under 'small' sits in the same page, could be split into different pages under 'fast'. This can result in more page faults. The performance impact due to page faults can exceed the speed improvements made from 'fast'.
So, based on past experience, and that these days the difference in optimization strategies is generally minor, I still use 'small'.
I haven't experienced the compiler ignoring my inline settings yet, have to check that, thanks.
The memset issue ... I ran into the same things years ago and found the following:

...cmk
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

Excel automation. How to save as *.xls with Excel 2010?
The default extension is *.xlsx, which is uncompatible with Excel 2003.
I want to save as *.xls.
Any one can help?

Have you looked at the first and second arguments to the SaveAs() method? By specifying an extension of "xls", it should use a v11 or v12 file format (rather than a v14 file format having a "xlsx" extension)?

I build MFC project "czsj", and put some source files out of the project folder. I have specify the "additional includes" of the project, but I still get the error message:
fatal error C1083: Cannot open include file: 'e:\work\t\czsj\excel.cpp': No such file or directory
I have also tried to set the global VC includes, but failed.
I think I can resolve the problem by specifying the search path of MS compiler.
Any one can help?
Thank you in advance!

It doesn't work. I have tried. I think I shoud specify the search path for compiler.

If it is the implementation files you're missing, you could just drag the missing cpp-files from windows explorer and drop them in your project tree, and they will be built from wherever they are stored.

The text of the error message is perfectly clear and tells you that the file excel.cpp cannot be found at that path. Why are you trying to include a source (.cpp) file in this way; you should add the file to your project (directly or indirectly) and build it as normal.

The compiler will never search for cpp files, you have to add them explicitly to your project, see the solution pane. Either create them inside your project, or add them ("Add Existing Item") if they already exist.
The one thing that gets looked for is header files (*.h), that is what all the "include" commands and directives are for.

Hi everybody
How can I send/receive SMS in c++(with PC) with a GSM Modem?
Is it possible?
Can I use MAPI for this?

Thanks a lot
I've read most of them already
I hope I can find a way with windows API, not sending AT command.
Regards

If you use a terminal such as hyper teminal you can practise with the AT commands you need to send SMSs. Once you have got these tuned, then you can put those strings into a C++ app (all it is going to do is send these strings to an opened COM port, as hyperterminsl does).
I wrote a driver some years back that does this, it isnt terribly difficult once you get the AT commands sorted out.
By the way, you must terminate the string in some kind of a carriage return, '\r' or '\n'. It is this that tells the AT processing engine in the modem to actually send the string, this could be what you are missing.
==============================
Nothing to say.

hello guys... I have got a project online. Now this project contains a function whose return type is LRESULT. Function's prototype and body are given as under.
afx_msg LRESULT FunctionName(WPARAM wParam, LPARAM lParam);
LRESULT ClassName::FunctionName(WPARAM wParam, LPARAM lParam)
{
}
But the problem is, I dont know how to add these sort of functions in application? Thanx for any help.

Just add the code into one of your source files where you need to use it. In the case of class functions you would add the prototype to the class definition in the header file and the body to the class source file. The sample code from any Visual C++ project will show you how to do it.

Hi all,
I want to make a priviewer in my application. i have also found a article on code project to preview files but it only priview files which have priview handler installed in registry, so it only preview word, excel files(i.e office Files). i want to priview all other files which are able to generate their priviews in windows priviewer pane. How can i do it.
Thanks in advance

If the files do not have an attached/attachable previewer then you will have to write your own, by creating some sort of view of the file content and rendering it to a bitmap which you can then display at whatever scaling you wish.

|
|
|
Actually i am not getting how to do it, so can you please tell me, how can i do this...
|
|
|
|

I thought I did! If there is no built in preview for a type of file then you will have to create one for yourself. This would involve writing handlers for every type of file that you encounter and rendering a view of their content as some sort of image.

If it was an SDI or MDI application, you had the option of Print/Print Preview when you created it. If you opted out of that, it can easily be added back in. Create another "test" application and make sure the Print/Print Preview option is checked. Once the application is created, look at the code that is specific to Print/Print Preview. That's what you'll need to add to your application.

extern DWORD mainThreadId;
PostThreadMessage(mainThreadId,WM_MESSAGE_THREAD,0,0);
I used this code to post a message from running thread to the main thread.
The message gets "intercepted" in the application class
BOOL CFD2008App::PreTranslateMessage(MSG* pMsg)
I does not get intercepted using same PreTranslateMessage in CMainFrame.
Now I need to run a process in CFD2008View.
How do I get the message there? All this in MFC.
Any constructive help will be as always appreciated.
Thanks Vaclav

When creating[^] the thread pass the CView pointer using the pParam parameter to the thread. In the thread use this pointer to post messages to the view.
