Forgive me, I'm not a proper JS programmer and still getting my head around a lot of concepts.
Suppose one had a group of similar, 2-frame/2-state rollover movie clips nested inside a containing clip, which has the instance name "Map". Each clip uses a 4 digit ID number preceded by an "s" as an instance name – e.g., "s6566".
Suppose one then wanted to capture those respective instance names to define a variable, such that one small script could allow each of these movie clips to display their ID on rollover/active state (in this case "6566"), across multiple files.
Ultimately I have thousands of these little clips spread across several dozen documents, and it seems it should be fairly simple to grab each symbol's instance name/ID, strip off the "s" from the beginning (there because instance names can't begin with a numeral), and apply said ID as dynamic text to it's respective symbol's rollover/active frame.
Is there a method of achieving this goal? I wish I had some example code to include here, but I'm not quite sure how to begin, other than to lay out the problem thusly. Haven't yet been able to find any info on capturing instance names, and I'm not sure whether it's possible. Thanks.
Children of MovieClips are stored as references using their instance name. You can see the format in the exported library JS file. Note that Animate will convert some instance names to remove unsupported characters or duplicates.
Here is some untested pseudo-code to get you started.
// You can iterate a MovieClip and get the names
for (var name in someMovieClip) {
// Ignore anything not starting with an s
if (name.substr(0,1) != "s") { continue; }
// remove the s
var newName = name.substr(1);
// The child can be accessed using bracket-access with its name
var child = someMovieClip[name];
// The child should have text instances if it is set up how you described
// Set the text to the newName
child.textInstance.text = newName
}
Don't forget to update the stage after you make changes. If you already have Ticker set up to do that, it should update immediately.
I hope that helps. If you have follow-up questions, let me know.

I am a relatively new user of Tabulator so please forgive me if I am asking anything that, perhaps, should be obvious.
I have a Tabulator report that I am able to print and create as a PDF, but the report's formatting (as shown on the screen) is not used in either output.
For printing I have used printAsHtml and printStyled=true, but this doesn't produce a printout that matches what is on the screen. I have formatted number fields (with comma separators) and these are showing correctly, but the number columns should be right-aligned but all of the columns appear as left-aligned.
I am also using Tree View where the tree rows are coloured differently to the main table, but when I print the report with a tree open it colours the whole table with the tree colours and not just the tree.
For the PDF none of the Tabulator formatting is being used. I've looked for anything similar to the printStyled option, but I can't see anything. I've also looked at the autoTable option, but I am struggling to find what to use.
I want to format the print and PDF outputs so that they look as close to the screen representation as possible.
Is there anywhere I could look that would provide examples of how to achieve the above? The Tabulator documentation is very good, but the provided examples don't appear to explain what I am trying to do.
Perhaps there are there CSS classes that I am missing or even mis-using? I have tried including .tabulator-print-table in my CSS, but I am probably not using it correctly. I also couldn't find anything equivalent for producing PDFs. Some examples would help immensely.
Thank you in advance for any advice or assistance.
Formatting is deliberately not included in these, below i will outline why:
Downloaders
Downloaded files do not contain formatted data, only the raw data, this is because a lot of the formatters create visual elements (progress bar, star formatter etc) that cannot be replicated sensibly in downloaded files.
If you want to change the format of data in the download you will need to use an accessor, the accessorDownload option is the one you want to use in this case. The accessors transform the data as it is leaving the table.
For instance we could create an accessor that prepended "Mr " to the front of every name in a column:
var mrAccessor= function(value, data, type, params, column, row){
return "Mr " + value;
}
Assign it to a columns definition:
{title:"Name", field:"name", accessorDownload:mrAccessor}
Printing
Printing also does not include the formatters, this is because when you print a Tabulator table, the whole table is actually rebuilt as a standard HTML table, which allows the printer to work out how to layout everything across multiple pages with column headers etc. The downside of this is that it is only loosely styled like a Tabulator and so formatted contents generated inside Tabulator cells will likely break when added to a normal td element.
For this reason there is also a accessorPrint option that works in the same way as the download accessor but for printing.
If you want to use the same accessor for both occasions, you can assign the function once to the accessor option and it will be applied in both instances.
Checkout the Accessor Documentation for full details.
Here's a chunk of code that WORKS when it's on the main timeline:
var DysonTarget:String = "S"+(random(40)+1);
this[DysonTarget].MyType = "Dyson Sphere";
this[DysonTarget].gotoAndStop(this[DysonTarget].MyType);
It's choosing a number between 1 and 40, adding an S before it, and going into one of forty movie clips on the main stage with instance name S1, S2. . . S40 etc. Then it will display an image in the chosen clip. But to make this truly work the way I want to, I have to put the above code inside a movie clip. So I tried this, after declaring my variable on the main stage:
_root.this[DysonTarget].MyType = "Dyson Sphere";
_root.this[DysonTarget].gotoAndStop(this[DysonTarget].MyType);
It didn't compile, the error message said "Expected a field name after the '.' operator. Trying it with _parent returned the same message. With _level0 didn't work at all, and placing the _root and _parent inside the bracket didn't work either. I haven't been able to find any answer online because trying to type "this" into a search is too vague to return an answer about the actual command.
. . .help me :(
A friend of mine who is a software developer helped me on this one. Here's what we figured out:
First you declare variable DysonTarget on the main timeline:
var DysonTarget:String = "S" + (random(40)+1);
Then inside the movie clip, use this:
_level0[DysonTarget].MyType = "Dyson Sphere';
_level0[_level0.DysonTarget].gotoAndStop(_level0[_level0.DysonTarget].MyType);
I've tried this a few other ways, and the above method is the only one that works the way it's supposed to. But it works! My impression is the brackets tell it to look for an object named what the variable is set to, rather than an object with the same name as the variable.
I just wanted to know how you put a cursor in a specific place in a live template for IntelliJ
For example:
# $var$ is an insance of the $objectType$ class
assert isinstance($var$, $objectType$)$END$
What happens here is that your cursor gets dragged to $var$ in the comment string first and then to your other values inside assert. What I wanted to know is how you chose where the cursor goes first.
I've read the documentation, but this is not mentioned, although a lot of other things are.
You can arrange the order that your variables are visited in. You find the information under bullet number five in this IntelliJ help document: http://www.jetbrains.com/idea/webhelp/creating-and-editing-template-variables.html
To arrange variables in the order you want IntelliJ IDEA to switch between associated input fields, use the Move Up and Move Down buttons.
Edit
You have to update the macro definition to similar to this:
# $varComment$ is an insance of the $objectTypeComment$ class
assert isinstance($var$, $objectType$)$END$
And then you define the order and expression to something like this (I didn't have any good expression for the var and orderType for you):
Since you fill in the Skip if defined for the two comment variable they will just take the values from the var and orderType and fill it in. This will do exactly what you are looking for :-)
Does anyone know of a method that allows you to search a string through a text file using StreamReader that allows you to account for multiple instances of finding the results. Basically I am creating a booking application and each time a customer books a seat, their PrimaryKey, FirstName, LastName and the co-ordinates of the seat on a data grid (which I have used as a method to book seats) are generated then saved to a text file.
I want the ability to be able to read multiple instances of a PrimaryKey then find the seat co-ordinates of each line that this PrimaryKey is listed on and repopulate another similar datagridview with these co-ordinates which is all going to be driven by a combobox index change.
It seems a bit complicated to understand but if anyone can help then please let me know.
I just need the knowhow of how to search multiple instances, so after its found the string once then look through the rest of the file to find another instance, I can do the rest by myself.
I'm coding using Visual Basic.Net
Yes it's possible to search multiple times through a file, but you'd either have to reopen the file, or rewind the stream (FileStream.Seek).
Wildly inefficient though.
If it has to remain an unsorted and unstructured file, build an in memory index to it.
If your key is an integer, create a Dictionary<int,int> of Key and Position in the stream.
Then when you want find key X you use FileStream.Seek to move to it, and read a line to get the data. If you find yourself grouping by say aeroplaneID, build a Dictionary<Int, List<Int,Int>>
where the key is the aeroplane id and the list is a list of primary keys and positions in the file.
You could push all that off to a background thread. You could try and get really clever and build them up as you need them. Personally though I'd be trying to move my storage to a more suitable format. You aren't struggling to do this because you've missed a class, you are struggling because you shouldn't.
Something like
Dictionary<int, int> _fileIndex = new Dictionary<int,int>();
using(FileStream fs = new FileStream(DataFileName,FileMode.Open,FileAccess.Read))
{
StreamReader reader = new StreamReader(fs);
int lastPosition = 0;
string currentLine = null;
while(currentLine = reader.ReadLine() != null)
{
String[] data = currentLine.Split(new char[] {','});
int key = int.Parse(data[0]);
fileIndex.Add(key,lastPosition);
lastPosition = fs.Position;
}
}
NB didn't test the above and there should be a bit more error checking in it. If there's alot of data in the line, then might be better off not suing split and just pulling out everything up to the correct delimiter. Also be careful how many indexes you keep live, wouldn't be long before they used up more space than just reading the entire thing in to memory.
Then you could create a class or structure to implement a line in the file, and write a bit of code
to use FileStream.Seek) to get there. If you wanted to load up a bunch of 'em it would make sense to get your list of positions of each one in the file and then sort them in order, then you could rip through the file in it's 'order' picking them out.
When I´m using MATLAB, sometimes I feel the need to make comments on some variables. I would like to save these comments inside these variables. So when I have to work with many variables in the workspace, and I forget the context of some of these variables I could read the comments I put in every one of them. So I would like to comment variables and keep the comments inside of them.
While I'm of the opinion that the best (and easiest) approach would be to make your variables self-documenting by giving them descriptive names, there is actually a way for you to do what you want using the object-oriented aspects of MATLAB. Specifically, you can create a new class which subclasses a built-in class so that it has an additional property describing the variable.
In fact, there is an example in the documentation that does exactly what you want. It creates a new class ExtendDouble that behaves just like a double except that it has a DataString property attached to it which describes the data in the variable. Using this subclass, you can do things like the following:
N = ExtendDouble(10,'The number of data points')
N =
The number of data points
10
and N could be used in expressions just as any double value would. Using this example subclass as a template, you could create "commented" versions of other built-in numeric classes, with the exception of those you are not allowed to subclass (char, cell, struct, and function_handle).
Of course, it should be noted that instead of using the ExtendDouble class like I did in the above example, I could instead define my variable like so:
nDataPoints = 10;
which makes the variable self-documenting, albeit with a little more typing needed. ;)
How about declaring another variable for your comments?
example:
\>> num = 5;
\>> numc = 'This is a number that contains 5';
\>> whos
...
This is my first post in StackOverflow. Thanks.
A convenient way to solve this is to have a function that does the storing and displaying of comments for you, i.e. something like the function below that will pop open a dialog box if you call it with comments('myVar') to allow you to enter new (or read/update previous) comments to variable (or function, or co-worker) labeled myVar.
Note that the comments will not be available in your next Matlab session. To make this happen, you have to add save/load functionality to comments (i.e. every time you change anything, you write to a file, and any time you start the function and database is empty, you load the file if possible).
function comments(name)
%COMMENTS stores comments for a matlab session
%
% comments(name) adds or updates a comment stored with the label "name"
%
% comments prints all the current comments
%# database is a n-by-2 cell array with {label, comment}
persistent database
%# check input and decide what to do
if nargin < 1 || isempty(name)
printDatabase;
else
updateDatabase;
end
function printDatabase
%# prints the database
if isempty(database)
fprintf('no comments stored yet\n')
else
for i=1:size(database,1)
fprintf('%20s : %s\n',database{i,1},database{i,2});
end
end
end
function updateDatabase
%# updates the database
%# check whether there is already a comment
if size(database,1) > 0 && any(strcmp(name,database(:,1)))
idx = strcmp(name,database(:,1));
comment = database(idx,2);
else
idx = size(database,1)+1;
comment = {''};
end
%# ask for new/updated comment
comment = inputdlg(sprintf('please enter comment for %s',name),'add comment',...
5,comment);
if ~isempty(comment)
database{idx,1} = name;
database(idx,2) = comment;
end
end
end
Always always always keep the Matlab editor open with a script documenting what you do. That is, variable assignments and calculations.
Only exceptions are very short sessions where you want to experiment. Once you have something -- add it to the file (It's also easier to cut and paste when you can see your entire history).
This way you can always start over. Just clear all and rerun the script. You never have random temporaries floating around in your workspace.
Eventually, when you are finished, you will also have something that is close to 'deliverable'.
Have you thought of using structures (or cells, although structures would require extra memory use)?
'>> dataset1.numerical=5;
'>> dataset1.comment='This is the dataset that contains 5';
dataset1 =
numerical: 5
comment: 'This is the dataset that contains 5'
