Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

You should avoid using this if possible; it's been deprecated for some time. Instead, you should use KeyboardEvent.code (for the physical key pressed) or KeyboardEvent.key (for the character the key maps to). Check compatibility for either property if you target very old browsers.

Note: Web developers shouldn't use the keyCode attribute for printable characters when handling keydown and keyup events. As described above, the keyCode attribute is not useful for printable characters, especially those input with the Shift or Alt key pressed.

Google Chrome, Chromium and Safari must decide the value from the input character. If the inputting character can be inputted with the US keyboard layout, they use the keyCode value on the US keyboard layout.

Warning: The purpose of these new additional rules is for making users whose keyboard layouts map unicode characters to punctuation keys in a US keyboard layout can use web applications which support Firefox only with ASCII-capable keyboard layouts or just with a US keyboard layout. Otherwise, the newly mapped keyCode values may be conflict with other keys. For example, if the active keyboard layout is Russian, the keyCode value of both the "Period" key and "Slash" key are 190 (KeyEvent.DOM_VK_PERIOD). If you need to distinguish those keys but you don't want to support all keyboard layouts in the world by yourself, you should probably use KeyboardEvent.code.

On Windows, some values of virtual keycode are defined (reserved) for OEM specific key. They are available for special keys on non-standard keyboard. In other words, some values are used for different meaning by two or more vendors (or hardware).

Starting Gecko 21 (and older than 15), OEM specific key values are available on the keyCode attribute only on Windows. So they are not useful for usual web applications. They are useful only for intranet applications or in similar situations.

Warning: The purpose of these new additional rules is for making users whose keyboard layouts map unicode characters to punctuation keys in a US keyboard layout can use web applications which support Firefox only with ASCII-capable keyboard layouts or just with a US keyboard layout. Otherwise, the newly mapped keyCode values may be conflict with other keys. For example, if the active keyboard layout is Russian, the keyCode value of both the \"Period\" key and \"Slash\" key are 190 (KeyEvent.DOM_VK_PERIOD). If you need to distinguish those keys but you don't want to support all keyboard layouts in the world by yourself, you should probably use KeyboardEvent.code.

Perhaps the correct thing to do would just be to change it so that the existing keycode field does what you need? Those values already vary between platforms, so as long as the enum constants like KeyPress::F1Key etc are correct, then that might work?

// Note that the actual values of these are platform-specific and may change // without warning, so don't store them anywhere as constants. For persisting/retrieving // KeyPress objects, use getTextDescription() and createFromDescription() instead.

Basically, I like the idea that jules had about using the already existing keycode field to contain the unique and platform dependent keypress description. At that point, if I understand conrrectly, the difficult part would be to make getTextDescription() and createFromDescription() play nicely with each other using an agnostic String representation of the keypress.

User ran the enable enterprise geodatabase on PostgreSQL database via ArcCatalog 10.8 but using an old 10.4 keycode file. The resulting geodatabase shows it's at version 10.9.1 but I wonder if it's missing anything. We are fully licensed with ESRI ELA so that's not an issue but the user didn't know they were pointing to a very old keycode file.

I would say as long as the Enterprise Geodatabase is reporting the correct version (i.e., 10.9.1 / 11.0 / etc.) based on the client used to create / enable it, and the license expiration date is correct, you should be fine.

I'm trying to remap my keyboard such that the Caps Lock acts as an additional Fn key, because the current one is in an awkward place (over by the Home and End). I was planning on using xmodmap, which requires keycodes to work. I have my Caps Lock keycode, which is 66, but to finish I need the keycode for the Fn. Using xev and pressing the Fn, I don't see anything. Any recommendations?

User keycodes are associated to an individual account and have the advantage of controlling each user's permissions to arm/disarm the alarm system through their unique keycode and site permissions.

General keycodes are not associated with an individual account; instead, they are given a generic name and are used for one alarm site only. The objective is to create a generic keycode for a group of people to use, such as janitorial staff or a master keycode in case of emergencies for that specific alarm site.

Required. You must have the alarms user permission to use this code tied to a user account. However, if you are a Site Admin, you are an alarm user, by default, for that site. This allows you to give users permission to arm and disarm a site and limit camera viewing.

Since I staarted this project I have had to reformat and wipe my computer out and start over 4 times. Three of those times it was because of Crystal Reports. Two of those reasons was for "Invalid Keycode". I am glad that I don't have a boss to have to explain this to and in the future I am clearly not sure I would ever use Crystal again.

In all of this, you have to keep in mind that there are thousands of downloads of CRVS2010 every month. As far as I remember, I have never head of anyone on these forums needing to reformat their drives due to a CR install (and I am quite active here...). E.g.; I'd start with; why is my experience on this computer so different? Why am I the lucky one needing all of these reformats - some due to CR and by your own admission some not...

If I sound frustrated then I'm sorry. Yes since I have started this project it has been an ordeal dealing with CR. I choose it after several people told me to stay away from it. with that said the one time that I had to reformat was because of a hard drive crash and it has been replaced scanned multiple times for errors and there are none. Also that was my first reformat and have since done that 3 times. I am using Crystal Reports for Visual Studio 2010. It is the only version that has ever been installed. here is the link from the CR website that i used to download.( _13_0_1.exe)

I am getting a dialog box when that says invalid keycode when I try to create a new report in the exsiting project and when I create a new project. I did search on crpe32.dll there are three tow of wich are in backup folders that i use and are associated with this applicationa nd wi thier version is 13.01.220. The third copyis in the C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86 folder it has the same version number. I do not have VS 2005 or VS 2008 installed

As i said if I sound frustrated i'm sorry but SAP has to look at the number of invalid keycode issues and say hey we have a problem with this. I truley am happy for the number of downloads you get every month for this product but how many are related to problems caused by the software its self? To ask me why my experience is so different from everyone else well I did. What answer would you like
