I'm learning programing windows applications with C++. Now I'm reading about messages and I'm playing with the spy++.
What function spy++ use in order to mark/highlight the window under mouse cursor?
Also, can you give me some tips about using MSDN? I'm my opinion is not user friendly at all.
I'm learning programming by myself and i can't get some real life experience tips as those which are learning at college or in teams.

Not sure exactly what your problem with MSDN is ... I tend to go to e.g. Win32 and COM development and look around for a suitable category in the listing to the left, then click down from there. Or just enter function names and search if I already know what I'm looking for but want the reference documentation. On the other hand, I'm not much of a Win32 developer.
I think spy++ is just inverting the colors directly on the window/screen DC (You could use InvertRect() for example) On Windows 2000 and later, it is probably better to use a translucent layered window if you actually wanted to implement this window highlight since some graphic corruption can occur when messing with other windows behind their back.
Writing a Windows application with just the windows API is possible, but you'll end up writing huge amounts of boilerplate code just to create simple things. This is why people normally use libraries built on top of it to make things easier - MFC for example.
The MSDN article Creating Win32 Applications provides a good explanation of the ins-and-outs of a Windows application using the Win32 API. Bare in mind though that you could build the same application in minutes using MFC.
I agree that MSDN is not the most user friendly source of information for a beginner. In my opinion it works much better as a reference.
My advice would be to focus on building some test applications using MFC (assuming you are tied to C++ as a language). Try looking at the codeproject MFC sections for example, and perhaps even buy a book to help get you started. This does of course require Visual Studio, but you can download the free express edition here

I'm developing my first Windows desktop application and I'm trying to figure out what the best approach would be to create the program's GUI.
I know, I know... I feel stupid for asking considering the amount of data on the subject on SO. However most answers seem outdated and I'm not sure if they fit my specific project. Also tutorials for Windows 8 'metro apps' are clogging my Google search results, which is NOT what I'm looking for.
I use Visual Studio. I've followed tutorials. I have basic knowledge of C and Java and extensive experience with PHP. I'm excited to learn C++, so I'm not looking for GUIs to create a GUI (like WinForms). I also don't care about managed code and portability for now, especially since I'm trying to avoid dependencies (i.e. users having to install .NET). As long as it runs smoothly on Vista and up, I'm happy.
The application
The software will teach basic physics to kids. I'd like to create a main area and a sidebar. The main area will feature a physics animation, say a bouncing ball, along with some Q&A. Users can zoom in to the animation to measure some stuff and answer the question. Users can track their progress in the sidebar. That's pretty much it.
What I've found so far
I'm getting a bit frustrated with MSDN. Most of their examples are given in four different languages (C#, C++, etc). I can't seem to get more than a bit of Hello World code from them.
I found a GDI API on MSDN and it seems like a good start for me. However I've read quite a few answers on SO saying creating layouts in pure C++ is really hard, that we're better of using frameworks like ATL and WTL. Since I'm also going to create (somewhat interactive) animations, I've wondered whether I should use gaming-targeted APIs like Direct2D.
Since all of this is new to me, and there are a lot of options, I don't know where to start for my particular application. Any tips would be greatly appreciated!
Using the raw Win32 API (no additional downloads or third-party helpers):
Here's a good primer (introduces dialog boxes, text boxes, buttons, etc): theForger's Win32 API Tutorial
And here's where you go from there (numeric up-downs, list boxes, combo boxes, tooltips, and more): Common Controls on MSDN. Most of these require you to #include <commctrl.h>.
I also found this to be a good resource that covered what the other two didn't: Win32 Developer - Window Assets
But the Win32 API doesn't seem like it does exactly what you want. A physics app for kids should have a more visual GUI than the API can provide. Good luck, though!
If you're ok with adding additional Frameworks, I'd suggest looking at Qt.
It allows to create the GUI from code only, has a good structure, and has an Interface for 2D drawing, if required.
If you are concerned about dependencies, you only have to include the Qt DLLs to your executables; no installation is required for the user.
To get started, see my (old) tutorial "Lessons in Windows API Programming".
But you really need a good book, such as edition 5 or earlier of Charles Petzold's classic "Programming Windows".
The problem with latest edition is that it's for C# and .NET, with Charles grabbing the tail of the "new way" at just the wrong time…
Disclaimer: I haven't checked the details of edition numbers.
Using the Windows API is the simplest, but producing advanced GUIs can take a very long time. Microsoft Foundation Class is a way to make the Windows API more user friendly and OOP. Does anyone have any experience with MFC?
Why not use some 2D C++ game engine, like HGE: http://hge.relishgames.com/overview.html.
I'm not very familiar with Linux, but have some experience with C and C++. I would like to get in touch with some Visual FX and/or UI development (either C or C++). I was wondering if there is a possibility to access the GUI elements of the Desktop on Ubuntu's Unity UI.
What I especially would like to do, is to render animations on the desktop or windows or all over the screen. (particle effects when clicking with the mouse or so).
Can anyone point me in the right direction? (Libraries, Documents, ...)
I think Desktop Effects have to be designed specific for the corresponding Window Manager.
I think unity uses (some sort of) compiz, so you should look into compiz plugin development.
A lot of "i thinks" so i am not really sure if that'll help you, but good luck.
You want to learn a lot more about GTK. There are lot of documentation on line (and some books also). You might code in C++ using GtkMM (but you could consider Qt also). GTK itself is coded in C, with well designed coding style and convention. Looking inside its source code is worthwhile.
Pretty much a self-explanatory title. I'm writing an application in C++ with the Win32 API, and I'd like to know how to minimize to the system tray. I can find all kinds of articles online about minimizing to the system tray in C#, Python, even Visual Basic, I think, but for the life of me I can not find a single article on how to minimize something to the system tray in C++.
Any and all help or even redirection would be highly appreciated.
EDIT: Question answered. Once I knew about the Shell_NotifyIcon function, I was easily able to find this CodeProject article which is exactly what I needed.
All you need is the Shell_NotifyIcon function. You ought to be able to work it out from MSDN, but if you need more help I'm sure there are a million places on the web that give samples. Now that you know the name of the API, web search will fill in the gaps.
I am new to c# and VS, but I am getting it. The application is this: A program in which the end result will draw a spider from options in which the user will define. Lets say there are 100s of options: size and number of body parts, color, connections points to the body, etc.
First question: Should I try to use the library included with VS 2005? Or, is there another environment in which I could "tap into" to get good results (flash, java, etc.)?
Second Question: Could you direct me to information corresponding to your answer from the first question?
Thanks so much, the kids I teach will love it!

Hmm.
This is truly a rough question, not because I don't know how to do it, but because it can often be so ridiculously daunting for beginners. If you use the "standard" Windows Forms C# method of doing it, you'll end up asking yourself, "What the #*(&! is WM_PAINT?" or "Why does my program totally get messed up when I move a window over my picture?!"
There are basically two main technologies that you can use to do drawing in .NET : Windows Forms (what MusiGenesis suggested) and WPF, or Windows Presentation Foundation, which ships with the 3.0 version of Visual Studio. That means that if you download the .NET 3.5 SDK or use Visual Studio 2008, WPF comes with it.
I'd recommend using WPF instead of Windows forms if you're just starting off, because the dirty details of drawing and repainting are largely abstracted. You can also define a lot of your picture as markup, just like a web page, and then manipulate it in code. Good luck and have fun!
Here is a link to some examples of how to draw things with C#:
http://www.geekpedia.com/tutorial50_Drawing-with-Csharp.html
This example uses just the built-in graphics methods of .NET, so you won't need any other libraries.
I see many user interface control libraries for .NET, but where can I get similar stuff for win32 using simply C/C++?
Things like prettier buttons, dials, listviews, graphs, etc.
Seems every Win32 programmers' right of passage is to end up writing his own collection. :/
No MFC controls please. I only do pure C/C++. And with that said, I also don't feel like adding a multi-megabyte framework to my application just so that I can have a prettier button.
I apologize for leaving out one tiny detail, and that is that my development is for Windows Mobile.
So manifest files are out.
I just notice how many developer companies have gone crazy with making pretty looking .NET components and wondered where the equivalent C/C++ Win32 components have gone?
I read about how many people ended up writing their own gradient button class, etc. So you would think that there would be some commercial classes for this stuff. It's just weird.
I'll take a closer look at QT and investigate its GUI support for such things. This is the challenge when you're the one man in your own uISV. No other developers to help you "get things done".
I've used Trolltech's Qt framework in the past and had great success with it:
In addition, it's also cross-platform, so in theory you can target Win, Mac, & Linux (provided you don't do anything platform-specific in the rest of your code, of course ;) )
Edit: I notice that you're targeting Windows Mobile; that definitely adds to Qt's strength, as its cross-platform support extends to WinCE and Embedded Linux as well.
The Code Project has lots of UI controls for C/C++
Most of them are focussed on MFC or WTL but there are some that are pure Win32.
As an aside if you're not using a framework, you really should consider WTL over pure Win32. It's low overhead and about a million times more productive.
For prettier buttons, etc., if you aren't already doing it, embed an application manifest so that your program is linked to version 6 of the common controls library. Doing so will get you the Windows XP- or Vista-styled versions of the standard Windows controls.
If you want types of controls beyond what Windows offers natively, you'll likely have to either write it yourself or be more specific about what kind of control you are looking for.
I you don't mind using the MFC libraries you should try the Visual C++ 2008 Feature Pack
Stingray
CodeJock - Toolkit Pro for MFC/ C++
The MFC feature pack is derived from BCGSoft components.
Using winAPI's you can do almost anything you want and really fast too. It takes some time to figure it out but it works. Go to MSDN, lookup MessageBox(), check out DialogBox() and go from there.
I personally do not care for MFC by the way. If you want to use an MFC like approach I'd recommend Borland's C++ Builder. Pretty old but still very usefull I think.
