  • Scriptaculous Draggable/Droppable script not working properly when dragging into a scrolling div

    - by George
    I am using the Scriptaculous Draggable/Droppable scripts and have a problem when dragging into a scrolling div. I have the following layout (based on this question): #grid-container { left:33px; position:relative; width:300px; } #grid { width:310px; height:400px; overflow:auto; margin-bottom: 15px; } #grid-container ul { width:400px; list-style-type:none; white-space: nowrap; } #grid-container li { display:inline; list-style-type:none; padding:5px 15px 5px 15px; height:88px; text-align:center } .image-row { margin-left: 10px; } .grid-image { height:50px; margin-left:-20px; } Here is the html: <div id="grid-container"> <div id="grid"> <div id="row1" class="image-row"> <ul> <li><img id="img1" class="grid-image" src="images/img1.jpg"></li> <li><img id="img2" class="grid-image" src="images/img2.jpg"></li> <li><img id="img3" class="grid-image" src="images/img3.jpg"></li> <li><img id="img4" class="grid-image" src="images/img4.jpg"></li> </ul> </div> <div id="row2" class="image-row"> <ul> <li><img id="img5" class="grid-image" src="images/img5.jpg"></li> <li><img id="img6" class="grid-image" src="images/img6.jpg"></li> </ul> </div> </div> </div> I have another div with draggable items, while all of the img elements are droppable. This works very well for most cases, but when there are too many images for the grid and it has to scroll, I run into issues. I can still drag/drop into most items in that div, but when I scroll down and then try to drag onto an item in the bottom of the list, it drops on the row that was at the bottom before I scrolled the div. Even if I set the scroll attribute when creating the Draggable items, it will scroll the grid div, but not use the proper Droppable item. Is there any way to make the Draggable items drop onto the proper Droppable element regardless of if the containing div is scrolled or not?

  • How do I get entity for primary key using EntityDataSource in ASP.NET

    - by drasto
    I have a GridView in my ASP.NET application that takes data to be rendered from EntityDataSource. GridView allows user to select rows. I want to get the entity that corresponds to the row user selected. I can get from GridView the ID(primary key) of the entity that corresponds to the row selected. How can I get the Entity that has that ID(primary key) ?

  • Calculating odds distribution with 6-sided dice

    - by Stephen
    I'm trying to calculate the odds distribution of a changing number of 6-sided die rolls. For example, 3d6 ranges from 3 to 18 as follows: 3:1, 4:3, 5:6, 6:10, 7:15, 8:21, 9:25, 10:27, 11:27, 12:25, 13:21, 14:15, 15:10, 16:6, 17:3, 18:1 I wrote this php program to calculate it: function distributionCalc($numberDice,$sides=6) { for ( $i=0; $i<pow($sides,$numberDice); $i++) { $sum=0; for ($j=0; $j<$numberDice; $j++) { $sum+=(1+(floor($i/pow($sides,$j))) % $sides); } $distribution[$sum]++; } return $distribution; } The inner $j for-loop uses the magic of the floor and modulus functions to create a base-6 counting sequence with the number of digits being the number of dice, so 3d6 would count as: 111,112,113,114,115,116,121,122,123,124,125,126,131,etc. The function takes the sum of each, so it would read as: 3,4,5,6,7,8,4,5,6,7,8,9,5,etc. It plows through all 3^6 possible results and adds 1 to the corresponding slot in the $distribution array between 3 and 18. Pretty straightforward. However, it only works until about 8d6, afterward i get server time-outs because it's now doing billions of calculations. But I don't think it's necessary because die probability follows a sweet bell-curve distribution. I'm wondering if there's a way to skip the number crunching and go straight to the curve itself. Is there a way to do this, so, for example, with 80d6 (80-480)? Can the distribution be projected without doing 6^80 calculations? I'm not a professional coder and probability is still new to me, so thanks for all the help! Stephen

  • Constant error in compiler using C#'s provided objects

    - by dotnetdev
    I have used the built in C# methods to write a compiler, like the following: CodeDomProvider codeProvider = CodeDomProvider.CreateProvider("CSharp"); string Output = "Out.exe"; Button ButtonObject = (Button)sender; this.RadTextBox1.Text = string.Empty; System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters(); //Make sure we generate an EXE, not a DLL parameters.GenerateExecutable = true; parameters.OutputAssembly = Output; CompilerResults results = codeProvider.CompileAssemblyFromSource(parameters, RadTextBox1.Text); if (results.Errors.Count > 0) { RadTextBox2.ForeColor = Color.Red; foreach (CompilerError CompErr in results.Errors) { RadTextBox2.Text = RadTextBox2.Text + "Line number " + CompErr.Line + ", Error Number: " + CompErr.ErrorNumber + ", '" + CompErr.ErrorText + ";" + Environment.NewLine + Environment.NewLine; } } else { //Successful Compile RadTextBox2.ForeColor = Color.Blue; Guid guid = Guid.NewGuid(); string PathToExe = Server.MapPath(Path.Combine(@"\Compiled" , Output)); FileStream fs = System.IO.File.Create(PathToExe); using (StreamWriter sw = new StreamWriter(fs)) { sw.Write(RadTextBox1.Text); } Response.WriteFile(PathToExe); When I run this code and write a Main method (such as the code sample in http://msdn.microsoft.com/en-us/library/ms228506(VS.80).aspx, I get this error: Line number 0, Error Number: CS5001, 'Program 'c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\Out.exe' does not contain a static 'Main' method suitable for an entry point; The code above is used as the basis of a compiler on my site (not yet live). So you type in code and generate an .exe assembly. But when I enter code into the textbox for code writing (Radtextbox1), even with a main method, I get the error. What gives? Thanks

  • In a SQL GROUP BY query, what value is used for the non-aggregate columns?

    - by Queencity13
    Say I've got the following data back from a SQL query: Lastname Firstname Age Anderson Jane 28 Anderson Lisa 22 Anderson Jack 37 If I want to know the age of the oldest person with the last name Anderson, I can select MAX(Age) and GROUP BY Lastname. But I also want to know the first name of that oldest person. How can I make sure that, when the Firstname values are collapsed into one row by the GROUP BY, I get the Firstname value from the same row where I got the max age?

  • Python, dictionaries, and chi-square contingency table

    - by rohanbk
    I have a file which contains several lines in the following format (word, time that the word occurred in, and frequency of documents containing the given word within the given instance in time): #inputfile <word, time, frequency> apple, 1, 3 banana, 1, 2 apple, 2, 1 banana, 2, 4 orange, 3, 1 I have Python class below that I used to create 2-D dictionaries to store the above file using as the key, and frequency as the value: class Ddict(dict): ''' 2D dictionary class ''' def __init__(self, default=None): self.default = default def __getitem__(self, key): if not self.has_key(key): self[key] = self.default() return dict.__getitem__(self, key) wordtime=Ddict(dict) # Store each inputfile entry with a <word,time> key timeword=Ddict(dict) # Store each inputfile entry with a <time,word> key # Loop over every line of the inputfile for line in open('inputfile'): word,time,count=line.split(',') # If <word,time> already a key, increment count try: wordtime[word][time]+=count # Otherwise, create the key except KeyError: wordtime[word][time]=count # If <time,word> already a key, increment count try: timeword[time][word]+=count # Otherwise, create the key except KeyError: timeword[time][word]=count The question that I have pertains to calculating certain things while iterating over the entries in this 2D dictionary. For each word 'w' at each time 't', calculate: The number of documents with word 'w' within time 't'. (a) The number of documents without word 'w' within time 't'. (b) The number of documents with word 'w' outside time 't'. (c) The number of documents without word 'w' outside time 't'. (d) Each of the items above represents one of the cells of a chi-square contingency table for each word and time. Can all of these be calculated within a single loop or do they need to be done one at a time? Ideally, I would like the output to be what's below, where a,b,c,d are all the items calculated above: print "%s, %s, %s, %s" %(a,b,c,d)

  • Lua Operator Overloading

    - by Pessimist
    I've found some places on the web saying that operators in Lua are overloadable but I can't seem to find any example. Can someone provide an example of, say, overloading the + operator to work like the .. operator works for string concatenation? EDIT 1: to Alexander Gladysh and RBerteig: If operator overloading only works when both operands are the same type and changing this behavior wouldn't be easy, then how come the following code works? (I don't mean any offense, I just started learning this language): printf = function(fmt, ...) io.write(string.format(fmt, ...)) end Set = {} Set.mt = {} -- metatable for sets function Set.new (t) local set = {} setmetatable(set, Set.mt) for _, l in ipairs(t) do set[l] = true end return set end function Set.union (a,b) -- THIS IS THE PART THAT MANAGES OPERATOR OVERLOADING WITH OPERANDS OF DIFFERENT TYPES -- if user built new set using: new_set = some_set + some_number if type(a) == "table" and type(b) == "number" then print("building set...") local mixedset = Set.new{} for k in pairs(a) do mixedset[k] = true end mixedset[b] = true return mixedset -- elseif user built new set using: new_set = some_number + some_set elseif type(b) == "table" and type(a) == "number" then print("building set...") local mixedset = Set.new{} for k in pairs(b) do mixedset[k] = true end mixedset[a] = true return mixedset end if getmetatable(a) ~= Set.mt or getmetatable(b) ~= Set.mt then error("attempt to 'add' a set with a non-set value that is also not a number", 2) end local res = Set.new{} for k in pairs(a) do res[k] = true end for k in pairs(b) do res[k] = true end return res end function Set.tostring (set) local s = "{" local sep = "" for e in pairs(set) do s = s .. sep .. e sep = ", " end return s .. "}" end function Set.print (s) print(Set.tostring(s)) end s1 = Set.new{10, 20, 30, 50} s2 = Set.new{30, 1} Set.mt.__add = Set.union -- now try to make a new set by unioning a set plus a number: s3 = s1 + 8 Set.print(s3) --> {1, 10, 20, 30, 50}

  • Bind DataGrid to Dictionary in ASP.NET

    - by mcoolbeth
    In ASP.NET, binding a DataGrid to a list of objects is super-easy. I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object. However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key? Thanks.

  • Need help with an AJAX workflow

    - by Anders
    Sorry I couldn't be more descriptive with the title, I will elaborate fully below: I have a web application that I want to implement some AJAX functionality into. Currently, it is running ASP.NET 3.5 with VB.NET codebehind. My current "problem" is I want to dynamically be able to populate a DIV when a user clicks an item on a list. The list item currently contains a HttpUtility.UrlEncode() (ASP.NET) string of the content that should appear in the DIV. Example: <li onclick="setFAQ('The+maximum+number+of+digits+a+patient+account+number+can+contain+is+ten+(10).');"> What is the maximum number of digits a patient account number can contain?</li> I can decode the string partially with the JavaScript function unescape() but it does not fully decode the string. I would much rather pass the JavaScript function the faq ID then somehow pull the information from the database where it originates. I am 99% sure it is impossible to call an ASP function from within a JavaScript function, so I am kind of stumped. I am kind of new to AJAX/ASP.NET so this is a learning experience for me.

    hi i have a NSTableView i have two columns A and B B contains some data A contains custom button the button is added to column A using this: Below code is placed inside awakeFromNib method NSButtonCell *buttonCell = [[[NSButtonCell alloc] init] autorelease]; [buttonCell setBordered:NO]; [buttonCell setImagePosition:NSImageOnly]; [buttonCell setButtonType:NSMomentaryChangeButton]; [buttonCell setImage:[NSImage imageNamed:@"uncheck.png"]]; [buttonCell setSelectable:TRUE]; [buttonCell setTag:100]; [buttonCell setTarget:self]; [buttonCell setAction:@selector(selectButtonsForDeletion:)]; [[myTable tableColumnWithIdentifier:@"EditIdentifier"] setDataCell:buttonCell]; Some code in display cell of nstableview: -(void)tableView:(NSTableView *)tableView willDisplayCell:(id)cell forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)rowIndex { if(tableView == myTable) { if([[tableColumn identifier] isEqualToString:@"DataIdentifier"]) { } else if([[tableColumn identifier] isEqualToString:@"EditIdentifier"]) { NSButtonCell *zCell = (NSButtonCell *)cell; [zCell setTag:rowIndex]; [zCell setTitle:@"abc"]; [zCell setTarget:self]; [zCell setAction:@selector(selectButtonsForDeletion:)]; } } } now i want that when i click on the button the image of button cell gets changed as well as i want to do some coding. When button gets clicked then by default the tableView's reference gets passed. How can i get the button cell reference i looked here for similar problem: Cocoa: how to nest a button inside a Table View cell? but i am unable to add button inside column of NSTableView. How i change the image: - (void)tableView:(NSTableView *)tableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row; { if(tableView == myTable) { if([[tableColumn identifier] isEqualToString:@"EditIdentifier"]) { NSButtonCell *aCell = (NSButtonCell *)[[tableView tableColumnWithIdentifier:@"EditIdentifier"] dataCellForRow:row]; NSInteger index = [[aCell title]intValue]; if([self.selectedIndexesArray count]>0) { if(![self.selectedIndexesArray containsObject:[NSNumber numberWithInt:index]]) { [aCell setImage:[NSImage imageNamed:@"check.png"]]; [self.selectedIndexesArray addObject:[NSNumber numberWithInt:index]]; } else { [aCell setImage:[NSImage imageNamed:@"uncheck.png"]]; [self.selectedIndexesArray removeObjectAtIndex:[selectedIndexesArray indexOfObject:[NSNumber numberWithInt:index]]]; } } else { [aCell setImage:[NSImage imageNamed:@"check.png"]]; [self.selectedIndexesArray addObject:[NSNumber numberWithInt:index]]; } } } } I have debugged the code and found that proper tag and titles are passed but image applies on more than one button cell, this is too very irregular. cant understand how its working!!! Any suggestions what am i doing wrong??

  • Listing down stored records localStorage | Google Chrome Extensions

    - by Jamie
    How do I get to list down the stored records in the for loop? Basically I want it to list down the records like this: '<div id="record_' + number + '">' + localstorage value + '</div>' The number in the class should add 1 every record, e.g. 1, 2, 3, 4 every record it lists down, and so on. The localstorage value should show the localStorage[] but the problem is, the localStorage name has the same, e.g. (clicks on button) it will save the value of the URL into a localStorage I then open the application and shows the window.html inside there is list of stored records by using this: '<div id="record_' + number + '">' + localstorage value + '</div>' INCLUDING the record number to add per record 1, 2, 3, etc... like this: <div id="record_1">localstorage value</div> <div id="record_2">localstorage value</div> <div id="record_3">localstorage value</div> <div id="record_4">localstorage value</div> <div id="record_5">localstorage value</div> <div id="record_6">localstorage value</div> etc...

  • Ruby on Rails ActiveRecord/Include/Associations can't get my query to work

I have no clue why this would ever happen My tables are as follows: schools: id name variables: id name type var_entries: id variable_id entry school_entries: id school_id var_entry_id my rails association tables are $local = { :adapter => "mysql", :host => "localhost", :port => "3306".to_i, :database => "spy_2", :username =>"root", :password => "vertrigo" } class School < ActiveRecord::Base establish_connection $local has_many :school_entries has_many :var_entries, :through => school_entries end class Variable < ActiveRecord::Base establish_connection $local has_many :var_entries has_many :school_entries, :through => :var_entries end class VarEntry < ActiveRecord::Base establish_connection $local has_many_and_belongs_to :school_entries belongs_to :variables end class SchoolEntry < ActiveRecord::Base establish_connection $local belongs_to :school has_many :var_entries end I want to do this sql query: SELECT school_id, variable_id,rank FROM school_entries, variables, var_entries, schools WHERE var_entries.variable_id = variables.id AND school_entries.var_entry_id = var_entries.id AND schools.id = school_entries.school_id AND variables.type = 'number'; and put it into Rails notation: here is one of my many failed attempts schools = VarEntry.all(:include => [:school_entries, :variables], :conditions => "variables.type = 'number'") the error: 'const_missing': uninitialized constant VarEntry::Variables (NameError) if i remove variables schools = VarEntry.all(:include => [:school_entries, :variables], :conditions => "type = 'number'") the error is: Mysql::Error: Unkown column 'type' in 'where clause': SELECT * FROM 'var_entries' WHERE (type=number) (ActiveRecord::StatementInvalid) Can anyone tell me where I'm going horribly wrong?

  • Need some advice on Core Data modeling strategy

    - by Andy
    I'm working on an iPhone app and need a little advice on modeling the Core Data schema. My idea is a utility that allows the user to speed-dial their contacts using user-created rules based on the time of day. In other words, I would tell the app that my wife is commuting from 6am to 7am, at work from 7am to 4pm, commuting from 4pm to 5pm, and home from 5pm to 6am, Monday through Friday. Then, when I tap her name in my app, it would select the number to dial based on the current day and time. I have the user interface nearly complete (thanks in no small part to help I've received here), but now I've got some questions regarding the persistent store. The user can select start- and stop-times in 5-minute increments. This means there are 2,016 possible "time slots" in week (7 days * 24 hours * 12 5-minute intervals per hour). I see a few options for setting this up. Option #1: One array of time slots, with 2,016 entries. Each entry would be a dictionary containing a contact identifier and an associated phone number to dial. I think this means I'd need a "Contact" entity to store the contact information, and a "TimeSlot" entity for each of the 2,016 possible time slots. Option #2: Each Contact has its own array of time slots, each with 2,016 entries. Each array entry would simply be a string indicating which phone number to dial. Option #3: Each Contact has a dictionary of time slots. An entry would only be added to the dictionary for time slots with an active rule. If a search for, say, time slot 1,299 (Friday 12:15pm) didn't find a key @"1299" in the dictionary, then a default number would be dialed instead. I'm not sure any of these is the "right" way or the "best" way. I'm not even sure I need to use Core Data to manage it; maybe just saving arrays would be simpler. Any input you can offer would be appreciated.

  • Changing the admin edit window display values

    - by Henri
    I have a database table with e.g. a weight value e.g. CREATE TABLE product ( id SERIAL NOT NULL, product_name item_name NOT NULL, . . weight NUMERIC(7,3), -- the weight in kg . . CONSTRAINT PK_product PRIMARY KEY (id) ); This results is the model: class Product(models.Model): . weight = models.DecimalField(max_digits=7, decimal_places=3, blank=True, null=True) . I store the weight in kg's, i.e. 1 kg is stores as 1, 0.1 kg or 100g is stored as 0.1 To make it easier for the user, I display the weight in the Admin list display in grams by specifying: def show_weight(self): if self.weight: weight_in_g = self.weight * 1000 return '%0f' % weight_in_g So if a product weighs e.g. 0.5 kg and is stored in the database as such, the admin list display shows 500 Is there also a way to alter the number shown in the 'Change product' window. This window now shows the value extracted from the database, i.e. 0.5. This will confuse a user when I tell him with the help_text to enter the number in g, while seeing the number of kgs. Before saving the product I override save as follows: def save(self): if self.weight: self.weight = self.weight / 1000 This converts the number entered in grams to kgs.

I want it to check if there is a blank cell in the datagridview, and if so, then skip printing the value out and carry on to check the next cell. Help appreciated greatly. Here is the code: foreach (DataGridViewRow row in this.dataGridView1.Rows) { foreach (DataGridViewCell cell in row.Cells) { if (cell.Size.IsEmpty) { continue; } MessageBox.Show(cell.Value.ToString()); } }
