How can I convert a length into a value in the range -1.0 to 1.0? Example: my stage is 440px in length and accepts mouse events. I would like to click in the middle of the stage, and rather than an output of X = 220, I'd like it to be X = 0. Similarly, I'd like the real X = 0 to become X = -1.0 and the real X = 440 to become X = 1.0....
i've tried several different variations of finding the length of a select element and nothing's working! i can't figure out why, since several websites list this is as the correct code. here's the javascript: <script type="text/javascript"> alert(document.getElementById("opentimes").options.length); </script> and here's the form...
I want to find out exactly how long the Response sent to the user was, after the fact, for logging purposes. Is there any way to do this from an HttpModule in asp.net (in the PostRequestHandlerExecute event). ...
I know that length(x) returns max(size(x)) and numel(x) returns the total number of elements of x, but which is better for a 1 by n array? Does it matter, or are they interchangeable in this case? EDIT: Just for kicks: Looks like they're the same performance-wise until you get to 100k elements. ...
Using Oracle SQL*Loader, I am trying to load a column that was a variable length string (lob) in another database into a varchar2(4000) column in Oracle. We have strings much longer than 4000 characters, but everyone has agreed that these strings can and should be truncated in the migration (we've looked at the data that goes beyond 400...
Suppose an app gets a content stream by being called with the android.intent.action.SEND filter. Also suppose the Uri and the stream is received like this: Uri contentUri = (Uri) extras.get(Intent.EXTRA_STREAM); InputStream in = getContentResolver().openInputStream(contentUri); Now, how can I determine the total length of the content ...
I am trying to optimize further the champion solution in prime number thread by taking out the complex formula for sub-list length. len() of the same subsequence is too slow as len is expensive and generating the subsequence is expensive. This looks to slightly speed up the function but I could not yet take away the division, though I do...
Hi, am being driven crazy trying to obtain how many lines a string will require as entered in a UITextView.

Are there macros or builtins that can return the length of arrays at compile time in GCC? For example: int array[10]; For which: sizeof(array) == 40 ???(array) == 10 Update0 I might just point out that doing this in C++ is trivial. One can build a template that returns the number inside []. I was certain that I'd once found a len...
Hi, I am facing a strange behaviour in jQuery 1.4 with the click event. The idea is to click on a drop-down list (change()), which then invert twice a collection of checkboxes by using the click() function of them. If I have to do so it is because the click on checkboxes update other fields, so I thought instead of inverting the checkbox...
