How can get whether Caps Lock is on or off?
I tried to search it but all I'm finding is how to toggle or turn it on/off which is exactly opposite of what I'm looking for.
I'm trying to do that in both C++ and Delphi.
Please help
I found this link and the code snippet below that might help you
if ((GetKeyState(VK_CAPITAL) & 0x0001)!=0)
AfxMessageBox("Caps Lock ON!");
else
AfxMessageBox("Caps Lock OFF!");
You want the GetKeyState() function:

with the VK_CAPITAL key code. Rest of the virtual key codes are here:

Use GetAsyncKeyState with VK_CAPITAL (0x14)

Can anyone help me with that? Sorry for not being specific, but that is what I must do. I have no idea about how can i do that, is there a way to reassign keys directly from TurboPascal?
You can try to replace the int $05 handler with an empty one as suggested by #500 - Internal Server Error.
I am trying to use ime (for hiragana input) in a flex 4 spark combo.
On creation complete I am setting the following.
cbx_text.textInput.imeMode = IMEConversionMode.JAPANESE_HIRAGANA;
And to check, tracing the following:
trace(cbx_text.textInput.enableIME); returns true;
trace(cbx_text.textInput.imeMode); returns JAPANESE_HIRAGANA;
However, when I select the text input and start to type some text I am unable to switch to hiragana.
I can set it to work on a textinput component with no problems.
<s:TextInput imeMode="JAPANESE_HIRAGANA"></s:TextInput>
Has anyone had any experience with this?
Any insights much appreciated.
Although I haven't had any experience with IME, I took a quick look at the documentation : http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/system/IME.html
Can it be that it's not enabled application wise? That, maybe what returns true is only valid for the component you are tracing from?
Obvious questions first:
Are you certain the TextInput is a member of cbx_text? I know this seems silly, but it's best to eliminate the obvious first.
Do you have an IME enabled on your computer? For example, do you regularly type in hiragana on your computer and have the appropriate language pack enabled?
Are you sending the IME the string appropriately? IME.setCompositionString() for windows computers?
Does your OS support the use of IMEs? Linux only supports the following methods:
Capabilities.hasIME
IME.enabled <= Can set or return value.
Try tracing hasIME and see if it's installed. Again, we're shotgunning here – trying to track down any possibility of a problem.

Edit: Turns out, I was misled during my initial explorations of the accessibility APIs. Once I found the secure text field in the AX hierarchy, I was easily able to set the value. Not sure what to do with this question beyond that, but I wanted to update this for future searchers.
I'm working on some code that will post keyboard events to targeted applications using the Accessibility APIs. So far, I have been able to write a trivial app that allows me to type in a string value and then post keyboard events with those key codes to the targeted application. In reality, the strings would be read from another location.
What I have not yet been able to figure out is how to ascertain whether and which modifier keys should also be posted. For instance, when I type Hello, world! into my test application, the input is sent to the other application as hello, world1 because I am not yet including the modifier keys to create the upper case H and the exclamation point. This is made doubly complicated by multi-keystroke characters like é or ü. Sending é sends a raw e with no accent for example.
Is there a simple method I am overlooking for discerning the modifiers to combine with a keycode for creating a particular NSString or unichar? If not, does anyone have a suggestion of how to proceed? So far, the best I have come up with is calling UCKeyTranslate with all possible modifier combinations until I find one that matches the unichar I get using -[NSString characterAtIndex:] I'm not sure this is scalable or reliable, though, given the multi-keystroke nature of some characters as noted above.
Thanks in advance!
This probably won't help. But just in case: Is it really necessary to send keyboard events? Because that is going to get really difficult if you need to support, say, Kotoeri.
It's a simple matter to override insertText: and doCommandBySelector: and send the results of the key sequence, rather than the individual keystrokes.
I have found a example which does the trick but it's incomplete:It will not be a general solution in any case ...how can this handle multiple keyboard layouts ?
There is an cgquartz obsolete function to do so: CGPostKeyboardEvent (not sure it's possible to pass only the char?) may be can still be used (marked undocumented with some side effect to but .. ).
EDIT: UCKeyTranslate as a way to build a dictionary. Interesting but how the OS do this? A better answer should be hidden somewhere !
I have an application that has 'macro' capabilities. When I map some keys on the keyboard to perform the 'macro', I can also have it launch vbscript instead.
What i'd like to try and do is within my vbscript figure out what keys were used in order to launch the script. Is it posible to do this? Could there be a way in vbscript to figure out what keys were last touched on the keyboard and then I could apply my logic.
The purpose of doing this is to keep the code in a single .vb file instead of several seperate .vb script files(one for each keyboard mapping, possible 3-4). Obviously we are looking to just maintain 1 file instead of multiple files with essentially the same code in each one.
I am leaning towards the idea that this is not possible, but i figured this would be a worthy question for the masses of StackOverflow. Thanks for the help everyone!
What you are asking for is not possible.
Can you change your VBScript to accept parameters and then call it with a different parameter based on which hotkey was selected?
I agree with aphoria, the only way to make something like this possible is if your keyboard mapping software allows you to assign a script/command with parameters/arguments. For example if you used
c:\Temp\something.vbs
then you would change this to
%WINDIR%\system32\wscript.exe c:\temp\something.vbs "Ctrl-Alt-R"
Then in your vbscript code you could collect the argument using the wscript.Arguments object collection to do actions based on what argument/parameter was passed. See the following two links for more info:

The one possible approach you may use is to install keylogger and read its log in your VBScript.
For example save script start time in the very beginning of the script
StartTime = Timer()
and then read one log record of your keylogger before this time.
I want to write a Songbird extension binds the multimedia keys available on all Apple Mac OS X platforms. Unfortunately this isn't an easy google search and I can't find any docs.
Can anyone point me resources on accessing these keys or tell me how to do it?
I have extensive programming experience, but this will be my first time coding in both MacOSX and XUL (Firefox, etc), so any tips on either are welcome.
Please note that these are not regular key events. I assume it must be a different type of system event that I will need to hook or subscribe to.
This blog post has a solution:
http://www.rogueamoeba.com/utm/posts/Article/mediaKeys-2007-09-29-17-00.html
You basically need to subclass NSApplication and override sendEvent,
looking for special scan codes. I don't know what songbird is, but if it's
not a real application then I doubt you'll be able to do this.
Or maybe you can, a simple category may suffice:
#implementation NSApplication(WantMediaKeysCategoryKBye)
- (void)sendEvent: (NSEvent*)event
{
// intercept media keys here
}
#end
Are you sure your multimedia keys are working in your installation? Every single key generates a scan code which is translated into a key code by the kernel. If xev doesn't show you any keycodes I guess those scan codes aren't mapped and so the kernel has no knowledge of them.
http://gentoo-wiki.com/HOWTO_Use_Multimedia_Keys has a nice explanation of finding key codes and offers help on how you can find raw scan codes and translate them into key codes.
xev might help you if you want to find out which codes are being sent by multimedia keys.
