Thanks all. 
I think I have to learn something about Windows Message from the most basic level...

Thanks for the feedback. Good to learn something new about Window's event handling!
I can understand that paint and mouse messages have a special handling (low priority generation) as MS has a GUI centric design... however I am surprised that MS hasn't stopped the special cases here. For example asynchronous network events (FD_ACCEPT, FD_READ) are posted to the queue and recurring is enabled by calling the matching network function, but on the other hand recurring timer events have again a special handling... kinda inconsistent. WM_QUIT came really as a surprise for me, I see your point, just not sure if it really is necessary to guard application logic at this late shut-down stage.

background: I have an application that will call functions in a Win32 DLL, I wish to have a single function in the DLL that accepts two strings(webservice name, text to be passed to the webservice) and then calls the webservice passed in passing it the text.
This is to allow for the addition of new web services without the need to recompile the DLL, just to add a config to the calling app with the name of the new web service and the text to be passed in. The Dll only needs to pass back a success or fail to the calling app. can some help with how Can someone give me some guidance on this. I am not very strong with C++ so your patiance is much appriciated.

You need more that a "name" to use a web service.

I wrote an application which creates a hidden registry key using the embedded null technique. The key is created fine. However, when I try to open the key with NtOpenKey, I am unable to. If I try to open the key using NtCreateKey, it opens without error. I see this abnormal behavior on Windows x64 OS only - on Windows XP 32-bit OS it runs fine.
The error NtOpenKey returns (using LsaNtStatusToWinError()) is 2 ('File/path not found').
Has anyone run into this and is there a workaround for it?
Thanks!

Hello!
I want my desktop to be clean (without shortcuts), but I want fast access to programs too.
So I want to make a program that behave like a Windows toolbar (with autohide):
when I point the mouse to the top-left corner of the screen I want my toolbar to appear.
I know that with Windows XP I can make a custom autohide toolbar (with what ever I want, where ever I want),
but I want some some menus entry (like: games, apps...), transparency, sounds and others.
I think this will eat some memory (with all that transparency and sounds), so here's my idea:
I will write a simple MFC program, that run in the background, without any controls and place it on top-left corner of the screen.
When the mouse (OnMouseMove) is over the window (which is a little square) it will call the actual program (ShellExecute).
This little "call program" eat around 2,700k.
* Is there a way to optimize this program to consume less memory?
* Is there another way to make what I want with less memory?
(some Windows shell programming, but this is some advanced stuff and I'm a beginner).
Here's some others questions not related with above (I hope you don't mind that I will post them here):
1. I found on the web some classes derived from the CBitmapButton and from all of them I get an error like this:
error LNK2001: unresolved external symbol "public: __thiscall MCBitmapButton::MCBitmapButton(void)" (??0MCBitmapButton@@QAE@XZ)
where MCBitmapButton is the derived class. What is the problem?
2. How can I make the background of MFC window dialog 50% transparent, without making the controls (like buttons) transparent.
If I use SetLayeredWindowAttributes: with LWA_COLORKEY the buttons are opaque, but the background is completly tranparent.
with LWA_ALPHA the buttons and the background share the same level of transparency.
3. Is there a way to make a MFC window dialog to have gradient-transparency: from opaque to completly transparent?

We don't do people's homework. What you're asking for is trivial, and working it out will teach you valuable lessons in doing your own research. Of course, if you've tried and you're genuinely stuck, we'd love to help, just post your code and explain what's not working for you.

There are two types of questions that do not get answered here: Homework and those that are too difficult.
Guess which one you are asking.

Your own head usually (research),
I rarely ask a question and when I do, I rarely get an answer; because I do not ask it unless my research is giving none. But I continue researching to find the answer while I wait for some one to answer my question.

Hi all,
I am making one pure win32 windows application by selecting “Win32 Project” template in Visual C++ project type 2005 version. This is my first win32 application but I can’t understand how can I add more controls and use it in the main form created by CreateWindow() function. Or can I get some help or place where I can get tutorial about win32 applications.
Thanks in advance,
Priyank

I actually rated you too my surprise, good answer. I do not know what he is looking for exactly, but Win32 implies they want to know.

I need a visual c++ code which gets two arguments(year and month)from user and display corresponding calendar
program must use arrays and functions and define a class date.

So which part do you need help with: 1) visual c++ code which gets two arguments(year and month)from user, or 2) display corresponding calendar?
If you are using MFC, check out the CMonthCalCtrl class. Otherwise, create a SysMonthCal32 window class.

How can I turn off sounds in webbrowser control hosted in my application?
I mean sound when user or script clicks some link.
It seems it is turned on default in Windows Vista.
Thank you!

Hello,
Scenario: MFC dialog application. That contains a lot of regular controls but should also contain a hidden(invisible) button or checkbox. clicking on the button (or checkbox) will enable or disable some custom or expert capabilities. Only knowing the exact location of the button will allow the user to click and get the expert capabilities.
The invisible control should behave as a regular visible control.
I know that this is possible, due that I saw it on a demo application few years ago (That I don't remember its name), but I don't have the vague idea on how to code it.
Any idea on how to implement it with Visual C++ using MFC?
Thanks in advance.
