I have a proprietary application with the only way to pass data externally - drag and drop from other application (like dragging a file from Windows explorer). My question is, is it possible to simulate drag'n'drop from external applicaiton? Pure win32 solution preferred, dependencies like MFC and WTL could be included too.
Help!
I think it is possible, but you will probably need COM for that (I'm not sure though - there is a WM_DROPFILES message, and some related functions, but I couldn't find one for dropping data). See this article on MSDN.

I'm doing an automation script for installation wizards using AutoIt. I'm trying to handle window changes in some way.
Can some one explain how these GUI's work?
When I click on the Next button it looks just like the components in the GUI is beeing changed. Is this tha case? Or is a new window created and the old destroyed?
I've noticed that the process ID is the same for all windows.
I'm sure there is some way to know which "state" the GUI is in, or which step?
By the way. All the windows has the same title.
Thanks

This will be dependant on the program you are automating.
The easiest approach would be to look at what changes in the GUI between stages, likely candidates are if there is a label that is giving instructions for that step, or a button that has text changing (e.g. if the button says "Finish" then you know your at the end).
Most installer programs have child windows for grouping the controls of each stage. These are typically implemented as dialog resources (as can be seen when using something like reshacker on them). So although the window remains the same, the panels are being created/destroyed as appropriate. This is a very neat method of doing it, for the obvious reason that you don't need to have to code to create/destroy a lot of controls. Resource created dialogs don't have nice class names like windows sometimes do though, so this may not be a reliable way to check the state.
I know it's possible to take a dialog that you built yourself and parent it on another form. But is it possible to parent a standard Windows system dialog on a form that you designed?
Specifically, I'm trying to set up a form with multiple tabs that provide different ways to obtain a reference to data used by the program. One of those tabs should represent the file system, and the ideal way to do this would be with the standard Open dialog that can be instantiated with the COM identifier CLSID_FileOpenDialog.
Is there any way to take a system dialog and cause it to appear parented on another window, without the border, title bar, etc?
There are ways to use a hook, either via SetWindowsHookEx() or SetWinEventHook(), to grab a system dialog's HWND, then you can do whatever you want with it, such as call SetParent(). But just because you CAN does not mean you SHOULD. System dialogs are designed to run as their own windows, not embedded in someone else's window. A better solution might be to use the same Shell display components that are used by Windows Explorer (and system dialogs) via IShellFolder::CreateViewObject() or SHCreateShellFolderView(), or find a third-party solution that does the hard work of interacting with the Shell for you.
Is there any way to do so in C or C++ (I know that it can be done in C#, so if you know how to, it'd also help!)?
What I want is a way to, automatically and through my own application, associate a custom file extension with a custom icon. For example, something that would make all current and subsequent .foo files have an image of their own, instead of the bland white paper sheet default. Just like what Java does to .jar files and Dev-C++ to .c and .cpp upon them being installed.
Through my researches I've found a lot of related information about a thing called Shell or something. I wound up myself at this page, and as viable what it says may seem, I have no idea on how to implement it at all, nor grasp what exactly it is about. Sorry if I sound noobish!
OS is Windows.
First you need to know how to modify registry in c++, here is a post that explains that:
Registry and c++
In the link you provided you have the keys that you need to update
HKEY_CLASSES_ROOT/[yourextension]
the call to SHChangeNotify is only needed to tell explorer to refresh once you modified the icon.
I would like to make some hook in windows programs. For instance, Vodafone application have some MSN like popup that can't be hiddent. So, in that way, I would like to create my option to hide or not this popups. Can anybody tell me some tutorials (basic first) how to do that?
Thanks in advice.
You have to create system wide windows hook with SetWindowsHookEx with first param WH_CBT. You can hook on HCBT_CREATEWND event and return non zero value and window will be destroyed, but first you have to somehow recognize that this is right window, maybe according to window title or something inside that title.
Another thing is that you can't use managed code and C# for system wide hooks, since you have to make unmanaged dll in witch hook will reside. So you have to use C++ or Delphi, and if you are not experienced in win32 programming that would probably be very complicated task.
I understand the process needed to customize a right click menu going through the regedit etc. However I need to the ability to go multiple levels such as in applications like WinZip. Here's a picture for clarification of what I need

You need to write a Shell Extension; there is a guide for writing one in managed code (C#) here. It will involve doing a bunch of interop and implementing COM interfaces that the windows shell will consume, namely IShellExtInit and IContextMenu.
However, one could argue that writing a Shell Extension in managed code is not advisable; it will force windows explorer to load the CLR, (or any app that uses the standard windows 'Open File' dialog) - native code (C++) would be a better choice for this.
