I want to know if it's possible to bind any keyboard key in windows to do a action.
The action I want is, when I press "?" then it just types a text "Hello, This is new world" Automatically. Is this possible? If so then please help me out.
Here are a few places to start researching.
The functionality you are looking for is similar to the design of a key logger. the difference is you intend to consume the key as opposed to observe it and let it through

I'm trying to create an android-like keyboard in Delphi that appears when a textbox is in focus. I need to know some way to get this status of focus in all the programs so I can give a show in my form and send it forward
SetWinEventHook(EVENT_OBJECT_FOCUS, EVENT_OBJECT_FOCUS, ...) to register for focus changes. Once you know the window you check the class name for "Edit" and you can get the thread id and then get caret information from GetGUIThreadInfo if you need that...
I have added a .Net windows form inside a saleslogix windows plugin, every thing is working fine but on pressing the "Tab" key inside this control, instead of going on the next textbox the control goes to next plugin.
I have searched it a lot and can not find a work around for this, when I added a browser control in another saleslogix windows plugin, the page inside this textbox has multiple text boxes in it. To my surprise on pressing the tab key it worked perfectly and control goes to the next text box.
Any help is much appreciated.
That's an entirely normal mishap when you use Winforms (and many other UI class libraries) in a host application. Navigation keys, like Tab and the cursor keys as well as shortcut keystroke keys, need to be recognized regardless which control has the focus. One way to do so would be to implement the KeyDown event handler on every single control. That's excessively painful of course.
So it doesn't work that way, the keystroke is recognized when it is received by the message loop, before it is dispatched to the control with the focus. Overriding the ProcessCmdKey() method is the general way to do this. The base method takes care of navigation and recognizing menu and button mnemonics.
Problem is, it isn't the .NET message loop that is receiving and dispatching messages. It is the host application that has the loop. And it doesn't know beans about ProcessCmdKey(). So it doesn't get called and navigation doesn't work.
It tends to work in a WebBrowser because it is an ActiveX control. Which is designed to interact with its host. In particular it negotiates to decide which one gets to process the key. The IOleInPlaceActiveObject::TranslateAccelerator() method does this. Not the kind of plumbing available in .NET and host apps are rarely written to provide an alternative.
You could consider the "excessively painful" solution but pretty unlikely you like the sound of it. There's only one other decent way to fix this, you must call ShowDialog() to display your form. Now it is the .NET loop that dispatches and the Tab and cursor keys work fine. That tends to be unwelcome advice, dialogs can be pretty awkward. If you are lucky and know what you're doing and the host can deal with it (usually not) then using a thread can take the sting out of the modality. Asking the vendor for advice, particularly the threading aspect, would be wise.
I need to create a GUI working on windows that can be activated by pressing short cuts.
1. is it possible without setup class?
2. if not possible, just achieve pressing hotkeys and activate my program--how should i code it out--would be enough
thanks (I am using Qt for vs2012 add in to do the GUI)
I put some code up that starts a thread that does this. It is windows specific, but it does the job.
Clipboard Shortcut/Hotkey binding with Qt outside of application
One alternative to all of this, is to go to a shortcut to your program, go to its Properties, and then click on the shortcut area and type your desired shortcut. As long as it doesn't overlap with existing hotkeys that are registered in windows, it should work, without a hidden presence of your app in the system tray or some other background thread.
Hope that helps.
libqxt offers a QxtGlobalShortcut class that does what you want.
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.
In one of my other questions, I inquired about a shortcut to enable a particular feature in the VS2010 IDE. It looks like the only way to make it happen is through the Macro Recorder, which I have unfortunately never used (as it looks quite powerful!).
The straightforward way to make my macro would be to start the recorder with CTRL+SHIFT+R, then go to Debug -> Exceptions, check all of the boxes I want, click OK, and then stop the recorder. Unfortunately, all that I can see is that it opens the Exceptions window, and no more than that.
I figured that if the Macro Recorder doesn't record mouse events, then surely it must record keyboard events, but I was wrong about that, too. Upon editing my TemporaryMacro, I saw that the only thing it does is
DTE.ExecuteCommand("Debug.Exceptions")
What I really want to do is add a method that can enter keystrokes like DOWN, ALT+T, and ENTER.
I have googled like crazy, gone through MSDN, and checked here on SO. I am embarrassed to say that I have been unable to find any information about an object in DTE that allows me to send keystrokes! Hopefully, someone here will know how to do it!
This is the closest thing I've found to a document regarding keystroke automation: http://msdn.microsoft.com/en-us/library/8h31zbch.aspx
Edit: I figured it out how to send keystrokes, but how can you send them to popup dialogs???
Here's the code I tried:
Public Module RecordingModule
Sub TemporaryMacro()
DTE.ExecuteCommand("Debug.Exceptions")
System.Windows.Forms.SendKeys.SendWait("+{TAB}")
System.Windows.Forms.SendKeys.SendWait("{DOWN}")
System.Windows.Forms.SendKeys.SendWait("%T")
System.Windows.Forms.SendKeys.SendWait("{ENTER}")
End Sub
End Module
I couldn't get it to work, so I tried debugging, and that's when I realized what was happening -- SendWait doesn't get called until after the dialog is dismissed.
So does anyone know how to use the Macro Recorder to interact with popup dialogs via keyboard commands?
I don't think you can send keystrokes to the dialog box.
I would recommend that you take a look at AutoHotKey, from there you can define interactions with dialog boxes. It works outside of Visual Studio, so you will probably find many more uses for it.
