All is running well and fine, using the keybd_event function that is being imported (there might be better ways, but it is working fine). Now I want to add specific support for all of the numpad. Looking e. g. here http://msdn.microsoft.com/en-us/library/dd375731(v=VS.85).aspx or in the System.Windows.Input.Key namespace, I can easily find keys for Num0..Num9, as well as for NumLock. But.. I cannot find anything

And I can deal it as an iterable, but it's not a generator, because I can iterate over it more than once. By my limited knowledge, I know only a few data types such as String, int, float, list, dict, tuple, set. But yesterday I learned that enumerate() returns a special pair of data which can be used by dict() only once, thus it's a special tuple generator with (index_of_iteration, item) value Is this dict_keys object another "I don't know what it exactly

I need to clone on ci server using a deployment key and then push the tag created by the ci process. is that possible using a deployment key? 回答1: Edit2: This change currently has a sideeffect, as there are no users on deployment keys. So you will find some ugly messages like ERROR -> POST-RECEIVE: Triggered hook for non-existing user . The cache-invalidation (and possibly other things) are therefor not handled on write pushes through deployment-keys, which is a bit ugly. bundle exec rake cache:clear

In the "KeyDown" eventhandler, if the "e.KeyValue" is a number, I want to treat it as a number and store it as an int. So, if I hit "8" on the number pad, I don't want "Numpad8" I want the int value 8 that I can add or subtract or whatever. So, how do I convert from the KeyValue to an int? 回答1: I'd go with this solution: int value = -1; if (e.KeyValue >= ((int) Keys.NumPad0) && e.KeyValue <= ((int) Keys.NumPad9)) { // numpad

For example Dim coll as new Collection Dim str1, str2, str3 str1="first string" str2="second string" str3="third string" coll.add str1, "first key" coll.add str2, "second key" coll.add str3, "third key" I know how to retain the list of strings: first string second string third string Once again: is there any way to retain the keys? first key second key third key Note: I'm using VBA through AutoCAD 2007 回答1: I don't thinks that possible with a

The key [name] in the array is what I am doing a search on. Array ( [ 0 ] => Array ( [ id ] => 20120100 [ link ] => www . janedoe . com [ name ] => Jane Doe ) [ 1 ] => Array ( [ id ] => 20120101 [ link ] => www . johndoe . com [ name ] => John Doe ) ) If I did a search for John Doe it would return. Array ( [ id ] => 20120101 [ link ] => www . johndoe . com [ name ] => John Doe ) Would it be easier to rename the arrays based on what I am searching

Is there a better way to do this? 回答1: There is no way to get the count of keys in a bucket without listing all the objects this is a limitation of AWS S3 (see https://forums.aws.amazon.com/thread.jspa?messageID=164220 ).

The code is below require 'net/ssh' keys = ["path_to_private_key"] Net::SSH.start('host', 'user',:keys => keys, :verbose => :debug) do |ssh| #ssh code end Using ssh directly from the command line works: ssh -i <path_to_private_key> user@host Do I have the the ssh API wrong? I have tried both 'user@host' and just 'user' as the username with the same result. Here is the debugging output: D, [2011-07-26T19:42:00.135148 #3511] DEBUG -

So I downloaded what I think is a OpenPGP key ... $ wget ftp : //ftp.isc.org/isc/bind9/9.9.4/bind-9.9.4.tar.gz.sha1.asc ... then I tried to "import" this key like this ... $ gpg -- import bind - 9.9 . 4.tar . gz . sha1 . asc ... but I get this error message: gpg : no valid OpenPGP data found . gpg : Total number processed : 0 What am I doing wrong? Thanks! 回答1: The command syntax is gpg bind-9.9.4.tar.gz.sha1.asc . Of course, this

I believe I have the correct candidate keys, but if someone could verify that would be great. I am also just having trouble finding superkeys. I don't know if there is a general formula to find them or whatnot. Here is the question: Relation Schema: U(A,B,C,D) FD's: A-->B B-->C C-->D D-->A I found the Candidate keys to be: {A},{B},{C},{D}. If someone could verify if this is correct, I would greatly appreciate it. Also if you could let me know how to
