Best recommendation is the "the" book about system programming: Jeffrey Richter, "Programming Applications for Microsoft Windows", ISBN: 1572319968.

This book covers all about threads, processes, synchronisation, memory management, DLLs and much more. It does this a pure API-centric way (no MFC, ATL or similar stuff) in C/C++.

Check out 'Win32 Multithreaded Programming' by Cohen & Woodring, available on O'Reilly press. It covers both Win32 API and MFC methods, and takes you from the very basics of threading right through to the most complex stuff; it's well presented and easy to follow too.

PropertySheets :: MFC

Hi.

I have a propertysheet with a multiple propertypages. I would like get two functions working.

1) enable/disable default buttons (IDOK, IDCANCEL, ID_APPLY_NOW) in the propertypage.

2) be notified when the user navigate to and from different propertypage. If possible set the active propertypage programmically.

Okay. I believe this is the way to enable/disable the default buttons of a propertysheet from within the propertysheet.

-----
// disable the OK button

GetDlgItem(IDOK)->EnableWindow(FALSE);
-----

However, the code above does not work from within a propertypage. Is there a way to accomplish the above without sending a message to main frame?

I have no idea on what message to catch as the user navigates to and from propertypages.

Thanks,
Kuphryn

I guess this should work:

GetParent()->GetDlgItem(IDOK)->EnableWindow(FALSE);

i need to create a menu similar to visual c++ menu: can drop buttons on it and more.

i am sure vc menu bar is not common menu, but i don't know what exactly it is: based on CToolBar, CDialogBar or others, and how to implement it.

do u have sample or idea?

thx

I'm not exactly sure what "can drop buttons on it and more" means, but I think all it is, is an owner-draw menu, thats coded to be more interactive. I could be wrong...probably am.

thx, but u r ..., things are not so easy.
if u want to learn socket, copy all of vc samples to ur hard disk from cd, then do a search (from vc 'search in files') for CSocket. u can find what u need: easy to learn. but the sample includes 2 parts: server and clint, find both. u will learn in several hrs if u r not a beginner for MFC.

Z order of dialog boxes

in a program, i display several (can be any more) modeless dialog boxes, those dialogs may be overlapped each other.

when user moves mouse over dialogs, i need to do different operations for each one according to their z-order.

top dialg is easy to handle because it has mouse msg, but how to know z-order for others?

thx

If the dialogs have a common parent, you can use EnumChildWindows to list them according their Z orders.

thanks a lots.
i never use the function before.
u mean, for a special dialog box, it may be second from topmost or third or any, the function can detect the 'number'?
note: the number is changed by mouse click dynamically, not by creating.
hope get ur opinion before my testing.

It is not as simple as you'd wish, you'll have to work out your way from what EnumChildWindows does. This function calls repeatedly a callback function provided by you listing all child windows according to their Z order. In your callback you'll have to compare what you're given with the dialogs and use that info to assign them the corresponding Z "number".

Used TRACE for the first time--its wonderful!

Its awesome! I'd been popping up clunky messageboxes which sometimes caused me grief while debugging. TRACE is just too cool. I'm sure theres a lot of debugging tricks one can employ with TRACE.

And if you're ever not using MFC, you can use OutputDebugStr anywhere you like.

Year, thats the really cool thing. (I usually do not use MFC...)

However, I liked the printf-style comfort of TRACE, so I wrote this small wrapper around OutputDebugString and use it quite frequently:

int DBGMSG( LPCSTR pszFormat, ... )
{
	char szBuffer[ 1024 ];
	
	// format text...
	va_list Params;
	va_start( Params, pszFormat );
	int cchWritten = vsprintf( szBuffer, pszFormat, Params );

	// ...and send it to the debugger
	OutputDebugString( szBuffer );
	return cchWritten;
}

i installed english OS, if i run a software, i.g. NjStar, which supports another language, internet explorer auto knows and displays right languages.

now i have a program (client) which needs to know if user is running NjStar or any similar software, if so, client tells server about this then server side will send right language to user.
what should i do inside client's coding to detect that?

thx

CString and char* quick question

ns25-Jul-02 5:20

25-Jul-02 5:20

If I have a char* abc and CString xyz, it is correct to do

xyz = abc? I am not by choice being given char* and I want to make them into CStrings so I can process them comfortably. SO I guess my question is, how do I convert a char* variable into a CString (I dont mean convertthe address stored in the pointer, but store whatevers located at that address ). Please help!!!
Thanks,
ns
