I keep reading tutorials of how to use it in Silverlight Apps, but I need it in XNA. All tutorials refer to the package Microsoft.Xna.Framework.GamerServices, but there is no such class...
What am I getting wrong?
You're probably not going to want to show the message box class via XNA unless you truly are displaying some type of system type message.
If you're just planning on communicating something via your game to your player, then you'll want to roll your own so you can theme it appropriately to match your game.
Otherwise, the above answer about using GamerServices is correct, that's how you display a MessageBox via XNA but again, you should really restrict your usage of that class for purely system type messages (e.g. "You must be signed in to purchase this game.")
First, check that you have a reference to the Microsoft.Xna.Framework.GamerServices assembly (in the 'Solution explorer' window, expand 'References'). If you don't, add it (right click on 'References', and click 'Add reference'). Then, you can use Microsoft.Xna.Framework.GamerServices.Guide.BeginShowMessageBox to display a message box.
If you can't get the other suggestions to work for you, I recommend checking out the Game State Management sample. It has its own message type popup windows. But more than that, it is a great starting point for any XNA game.

I need my Visual Studio extension to react to debugging events. I've registered a IDebugEventCallback2 and I'm receiving events, but all I get for each event is an opaque IDebugEvent2 and a Guid, many of which are not only undocumented but don't appear anywhere on the web (or in my registry).
My specific requirement at the moment is to know when the process is Continued - ie. the user has hit Continue, Run to cursor, etc. What Guid should I be looking for?
Or is there some other event family that I should be subscribing to?
(More generally, is there some way I'm missing to find out about the events that are delivered to my IDebugEventCallback2::Event callback, when many of them don't appear in MSDN or anywhere else? Thanks!)
There is no easy way to do this. Actions such as Continue and Run to cursor are abstractions implemented by Visual Studio and do not correspond to any unique event(s) with respect to the debug engine. The debug engine event reporting interface IDebugEventCallback2 will enable you to get notified only on fine-grained events such as when creating a breakpoint or reaching a breakpoint.
While Visual Studio enables you to perform actions such as Continue and Run to cursor programmatically, it does not provide a direct way to get notified when they are taken.
You can use EnvDTE.DebuggerEvents.OnXxx events to get notified when something is about to happen. In particular, the OnEnterBreakMode event enables you to intercept a breakpoint hit and possibly take an action. You can also inspect all the details of the reached breakpoint(s) using the current EnvDTE.Debugger inside the event handler.
Now with some effort, you can use these constructs to implement events that correspond to all Visual Studio debugging actions including Continue and Run to cursor accurately. If you require additional events not provided by EnvDTE.DebuggerEvents (such as when a breakpoint is inserted), you have no choice but use IDebugEventCallback2.Event. In this case if you have specific events in mind, please mention them explicitly and I might be able to tell you the corresponding IDebugEventCallback2.Event GUIDs.
You probably got off on the wrong foot here, the IDebugXxx interfaces were really intended to create your own debugging engine. Still useful perhaps to see what is going on in the existing engine, you are suppose to use QueryInterface() to discover the specific interface that matches the event. Like IDebugEngineCreateEvent2, IDebugProcessCreateEvent2, IDebugProcessDestroyEvent2, etcetera. There are a bunch of them, they are listed in the VSSDK\VisualStudioIntegration\Common\Inc\msdbg.h header and include their IID.
Best thing to do is peek at this sample, it shows how to crack the event notification into the specific interfaces. The AD7Events.cs source file shows the wrappers. Do keep in mind that this sample was made to show how to create an engine, not how to use the one already built into VS.
But yes, you are not going to get a "continue debug" event out of this. A debugging engine does not need that event since it is already responsible for taking care of that by itself. It already knows when it calls IDebugProgram3::Continue().
Surely what you are looking for is IVsDebugger.AdviseDebuggerEvents(). That's the one that tells you what the built-in debugger is doing. You need to pass an object of a class that implements IVsDebuggerEvents, your OnModeChanged() method will be called with a DBGMODE notification. I don't see a lot of fantastic examples that demonstrate usage, this web page might be helpful.
Dropbox has the option of adding a button to the Finder toolbar. It even appears in the 'Customize Toolbar...' window.
I can't find any documentation on how this sort of thing is done.... Does anyone know how to do this, or can anyone point me towards some documentation or sample code?
EDIT ONE:
I guess a start would be finding the location of the existing icons, and any related code.
I noticed that Dropbox has files in Library/DropboxHelperTools/Dropbox_u501 called mach_inject_bundle_stub.bundle and FinderLoadBundle which might be doing the magic. Dropbox is also putting the 'tick' badge on Finder icons. This code might be involved: github.com/rentzsch/mach_star
EDIT TWO:
A Dropbox talk by Rian Hunter about the process is here, at around 15:30
http://blip.tv/pycon-us-videos-2009-2010-2011/pycon-2011-how-dropbox-did-it-and-how-python-helped-4896698
Looking in the DropboxBundle file in the Dropbox_u501 shows the icons and some compiled code. The code suggests that Rian Hunter is the author: http://twitter.com/timeserena
Rian has his own version of the Mach Star code on his github - https://github.com/rianhunter/mach_star - tho it seems much older
EDIT THREE
There was a 'Code Injection Workshop' at Stanford a few weeks ago - http://stanfordacm.com/past/ - hosted by Rian. If anyone has notes from this please let me know!
You can use Finder Sync app extension(Starting in OS X v10.10).
A Finder Sync extension can:
Add, remove, and update badges and labels on items in a monitored folder.
Display a contextual menu when the user Control-clicks an item inside a monitored folder.
Add a custom button to the Finder’s toolbar.
Dropbox was using undocumented magic. There's no officially supported way to do this; the closest you can get without reverse engineering is Services.
(Update: As of macOS 10.11, what Dropbox was doing is no longer possible at all. System Integrity Protection now prevents code from being injected into system processes, such as the Finder.)
Rian's talk at PyCon 2011 (on blip.tv) does not explain anything more than "We reverse-engineered Finder." Although the mach_star stuff is valuable, it still doesn't explain how to get a sidebar icon working. And the Stanford 'Code Injection Workshop' has not posted any content about this method.
I've nm'd and class-dump'd both bundles that Dropbox installs for each user under /Library/DropboxHelperTools, and the output provides good insight. If I get back to it, I'll finish my research and post it. Odds are, it won't be for some time, so here's hoping this nudge helps someone else.
An easy intermediate answer that may be adequate for some people is to simply create icons that look like buttons.
e.g. I created 'new text file here' and 'new terminal here icons' for my Finder:
The method can be found here.
The disadvantage is that they must be square and do not have animations/menus or show up in 'customize toolbar' etc.
Open a TextEdit document with a few words in it. Notice that when you right click on a word, you can click "Look up (Word)" to get its definition or "Speech Start Speaking" to hear it read out aloud.
How can I build a local application to monitor globally whenever a user has requested a dictionary definition or the speech synthesizer?
Couple of ways I can think of are
injection and Hooking. If its cocoa application you can also try swizzling. I think with this approach its very easy to manage what you are trying to do. But it can be lot of work.
If you follow apple techniques so they must be sending notification that can be catch between applications. Try to find them and you are done.
I'm working on a little macro record/replay tool which can automate a few very old Visual Basic 6 GUIs we have. To do so, I'm identifying the controls by their name (the value of the name property of a control, that is).
One part of this tool needs to determine the name of a control given its HWND. For newer Visual Basic applications which were done using VB.NET, I can use the WM_GETCONTROLNAME window message. This works nicely.
However, this message is not understood by older windows. Is there any way to do this for controls of Visual Basic 6 applications? A solution which does not require being in the process of the GUI would be preferrable, but if I had a solution which only works inside the GUI process then that would be acceptable as well (since I can do the injection myself).
UPDATE: One thing I just tried, this moderate success: I used the AccessibleObjectFromWindow to check for implementations of the IAccessible interface of the object which shows the given HWND. In case I get an implementation (it seems that many [all?] Visual Basic controls implement this interface), I use the accName property to read out the "accessible name". Sometimes this does yield a useful string, but usually it doesn't.
I believe the only way would be getting inside the process and obtaining a pointer to the Form object, yet I have no idea how to do it from outside.
Is it possible you add support for the WM_GETCONTROLNAME to those older applications?
Or maybe, you could identify the controls by some other, natively-available properties?
Other that that, as Raymond is saying, there isn't much you can do.
Can you modify the vb6 apps? if so in each form load event you could iterate me.controls and use the SetProp(ctrl.hwnd, "MYNAME:" & ctrl.name, 0) api to add the name to the window's own property list, then in your other app you can EnumProps(ctrl_HWND) looking for the one that begins with MYNAME: and parse out the value.
I'm facing some troubles still while learning, so I guess it tends to get worse once I play with the big kids: warnings in dynamics aren't as precise and informative as VS's, there are no mouse-over tips, and exceptions to show me exactly where I've got it wrong.
I'm just too used to Visual Studio, it's intellisense and all the tools (dynamics is quite new when compared to Visual Studio)
More than solving simple code issues, i'd like to learn how to solve upcomming ones i might have in code not written by me or anything else i'd solve in 3 minutes in Visual Studio, as well as tips on how to survive in dynamics ax without all the Visual Studio tools.
The code editor in Dynamics AX has some intellisense, typing the name of a table or class variable followed by . or :: will give you a list of fields or methods available for that item. After you type the ( to start a method call, a tooltip pops up with parameters available on that method. When starting a new line, you can right click and List Tables, List Classes, List Types, etc. Most of those commands are also available via Shortcut Keys. Note that the intellisense only works if all the code in the method up to the location of your cursor is syntactically correct.
Make sure you have updated the cross reference in your development environment (Tools/Development tools/Cross-reference/Periodic/Update). With an updated cross reference, you can right click an any table, field, class, method, extended data type, or enum in the AOT and choose Add-Ins/Cross-reference/Used by to see where that item is used in the system.
You can also use Tools/Development tools/Code explorer to view the source to the application with all types, variables, and methods turned into hyperlinks so you can click to go right to the definition of that item.
Another useful tool is Application hierarchy tree, available either under Tools/Development tools, or on the right click Add-Ins menu. This will show you the class hierarchy, so you can easily see, for example, that SalesFormLetter derives from FormLetter, which derives from RunBaseBatch.
In the editor, you can highlight text and right click to Lookup Properties/Methods or Lookup Definition.
If you are trying to track down where in the system a particular infolog message is generated there are two strategies to use:
Set a breakpoint on the first line
of the method Info.add(). Then when
you run the code generating the
message, you will pop into the
debugger as soon as the infolog is
generated. You can then look at the stack
trace in the debugger to see where the code is that
generated the message.
Run Tools/Development
tools/Label/Label editor and search
for the text of the message. Select
the Label ID of the message, then
click Used by to see where that
message is used in the system.
There is also http://www.axassist.com/ which extends intellisense and many other extensions
What these guys said already is very interesting and helpful.
I'd like to add that within AX in real life you are probably working with multiple contexts. e.g. Code running in the client, code running in server, code running in p-code and in IL, COM integrations, Enterprise portal and so on.
My point is, if you want to figure something out through debugging, you must first understand where the code(s) you'd like to debug is running.
Knowing that is important because you might have to allow debugging or give permissions in multiple places.
Examples:
Windows AD debugging users (add yourself)
Allow debugging on client
Allow it on server
Disable IL if you want to use MorphX, otherwise attach the process in VS.
Allow World Wide Web Publishing Service to interact with desktop for EP.
One last thing, you are starting to work with ax right now, perhaps you will need to work with AX7(Dynamics 365 for Operations). This version of the system works only with visual studio. It is still x++, but you have a lot of the things VS provides you.
Take a look on EditorScripts Class,On AX Editor you can use it by right click and choose "Scripts". It is a kind of intellisense that can make by your self, for example: here is my in-line comment whenever I type "mycom" and press "tab"
public void template_flow_mycom(Editor editor)
{
xppSource xppSource = new xppSource(editor.columnNo());
int currentline = editor.currentLineNo();
int currentcol = editor.columnNo();
Source template = "//Partner comment "+date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll )+" at "+time2str(timenow(), 1, 1)+" by MAX - Begin\n";
template+=strRep(" ", currentcol)+ "\n";
template+=strRep(" ", currentcol)+ "//Partner comment "+date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll )+" at "+time2str(timenow(), 1, 1)+" by MAX - End\n";
editor.insertLines(template);
//move cursor to the empty line between the comments
editor.gotoLine(currentline+2);
editor.gotoCol(currentcol+4);
}
