no, there is no built-in layer concept in VC++ or GDI. you'll have to come up with a custom layering mechanism.
i've done it by drawing each layer into its own CBitmap/HBITMAP, then drawing the Bitmaps into a final composite bitmap for rendering to the screen.

hai
I want some small rectangles on one layer. Then a line has to move from one end to another(which will be like drawing line ..erasing that and drawing next line in new position).This line I want in another layer so that the rectangles are not erased. When I tried to do both rectangles and lines together the rectagles are getting erased.So if i have them in separate layers then change inone layer will not affect the other. So is it possible to have line drawing in one layer and rectangles in another ?

How to know from the current CWnd object if the Parent CWnd object has been sized. If so how to get its new RECT size (to do modifications to the child (this) or (current) CWnd object).
I need this code. Please help me

Have you the parent's code ? 
virtual void BeHappy() = 0;

For example I wanna create a cool object : CoolButton & make that CoolButton
Anchored to the Parent CWnd. CoolButton must know if the parent CWnd has been changed its size, to make the CoolButton moves too

Hi everybody,
As i said, MAPIReadNext function return 0 and a pointer to unread message on windows live mail, but after it, if i send a MAPIReadMail command i receive a 0 return code again, but the pointer to struct message is NULL.
Portion of my code:
MapiMessage* message ; // Created but not initialized
ULONG err=0; // Created and initialized
LPSTR rgchMsgID; // Created but not initialized
// return 0 and put 546 into rgchMsgID
ULONG uFindRet = lpfnMAPIFindNext(lhSession,0L,"","",MAPI_LONG_MSGID|MAPI_UNREAD_ONLY,0L,rgchMsgID);
err = lpfnMAPIReadMail(lhSession,0L,rgchMsgID,MAPI_BODY_AS_FILE,0,&message); // Return 0
if (message==NULL) // true, because message is NULL.
err = FAILMAIL; // Badly, Allways execute this line.
Can someone help me ?
I try everything i knew.
since now, thanks.

Hello,
In my MFC MDI application, I would like to dock a set of side panes in tabs. For the tabs, I would like a 32x32 icon and no text, similarly to the 3ds max style:
http://mods.terranova-exp.com/tutorials/3dsmax5/images/tut_image_01.jpg (the one in the upper right side of the window).
Is this achievable using the CDockingManager, or are the 16x16 icon sizes hard-coded?
I am using VS2010 RC.
Thanks in advance!

tell me Books on WIN32 c++??
|

http://www.charlespetzold.com/pw5/[^]
Don't know if there are better ones these days, but this one book should be on every Win32 programmer's desk.
Watched code never compiles.

You will need to google this, Windows Development it's on MSDN.
The book alone won't help much, but MSDN with Windows Development topic should put you in the right path.
You need to focus on which Windows version you want to target!
Windows XP / GDI
Windows Vista / Direct2D (update)
Windows 7 / Direct2D
Focus on CreateWindow function and Common Controls! 
And Visual Styles...

not really.
AFAIK, basic Win32 should work for all versions of Windows.

not necessary IMO.

yea Maximilien is right.....tell me more books if anyone know...thankx Maximilien for the book
|

Visual Styles if he wants his apps to like shiny from Windows XP and later.
Windows 7
-New UI changes
-Location Services
-Direct 2D
... I believe these are more targeted towards Windows 7.

HI all,
Is it possible to link STL dynamically to my application? For me it is a bit confusing as template libraries are shipped as source. Hence making those in a DLL does not make sense. Please correct me if I am wrong.
The real problem here is I have a static library produced my latest compiler which uses STL. Now If my client want to use it this library with compiler of lower version, it gives STL class undefined error.
Please help.

Right.

I don't get you here: using a static library (so, basically a collection of functions and/or classes in executable format) should have nothing to do with such an error...

so if my static library is compiled with newer version of compiler and my client uses it in its code which is compiled with older version of compiler. Things should work fine?
This problem statment utimately boils down to
1) I have one static libray say "A" build with Compiler 2.0, uses STL
2) I have another static library "B" compiled with Compiler 1.0 uses STL
If I try to make my client application with Compiler 1.0. using both the libraries(A and B), will it work?
Does linker allows me to link two libraries carrying different STL instances? Can there be ambiguities or optimization issues?

But...
... the template sources (the only used) must be compiled,
there is no any template LIB/DLL in the nature...
virtual void BeHappy() = 0;

No, because you should not use STL across library boundaries...without really knowing what you do. First of all is STL not a binary compatible interface, you must compile with exactly the same STL version in all modules/libraries/DLLs. There is probably no linker warning/error if you try otherwise. Secondly allocating memory in one module's heap and deallocating in another will fail, if you do not provide special allocators. In short, there is no easy way to use STL in exported interfaces.
Some more background:

Hope it helps!

You are a software developer, aren't you? So, please, read the documentation and develop the software (we would help on that).

Hi..
'm working on my final year(engg) project..
I need to hide my process from the task manager..
developing a remote monitoring utility for a start-up company..
it would be great to achieve this hiding..
coding in win32 using C..
any suggestions as to where to look for would greatly help..
thank yu

Unless you are writing a virus, this is not a good idea. What if your process has a memory leak ? Or slows down the computer ? You have to let the user decides what he wants to do with his computer. And as far as I know, it is even impossible to hide a process this way.
(And if you are writing a virus, then asking such a question here is stupid).
