• How to draw/manage a hexagon grid?

  - by W.N.

  I've read this article: generating/creating hexagon grid in C . But look like both the author and answerer have already abandoned it. v(hexagonSide - hexagonWidth * hexagonWidth): What's hexagonSide and hexagonWidth? Isn't it will < 0 (so square root can't be calculated). And, can I put a hexagon into a rectangle? I need to create a grid like this: One more thing, how can I arrange my array to store data, as well as get which cells are next to one cell? I have never been taught about hexagon, so I know nothing about it, but I can easily learn new thing, so if you can explain or give me a clue, I may do it myself.

• UIImageView in UITableCell gets a weird size

  - by Behlül

  Hi, I'm trying to place a UIImageView in a UITableViewCell. I create a special view called ProductView. In that view, I have several components, one of them being a UIImageView. I set this ProductView as content view of the UITableViewCell. Everything is drawn properly except the UIImageView. UIImageView gets scaled meaninglessly. It's height gets twice the height of the table cell size. I've spent hours trying to solve this problem. I've set the frame of UIImageView manually, I've called drawRect method of UIImage in UIImageView, neither of them worked. I'm thinking of replacing UITableView with a UIScrollView if I can't find a solution. Does anyone know how to solve this problem?

• Assigning values to variable WHILE loop

  - by Milaan

  Hi! I have a WHILE loop that loops through a table as long as $i is less than 10. I want this loop to assign the INNERHTML of each cell to a variable. So that I can use it later on to process the information (the loop is because you can choose if it has to take first 3 or first 10 cells). But how do I assign every innerHTML to a different variable? I'm sure there has to be an easy way. But google couldn't get me a good answer. Thanks in advance! Milaan

• Pre-processing data before showing it in AdvancedDataGrid

  - by MinimeDJ

  Hi guys, I want to extend AdvancedDataGrid to show a Waterfall Chart in one of its columns. To do that I already created custom cell render that shows bars as I need. Now I have a little challenge: I have to pre-process data to show my Waterfall Chart properly. I have to do it before my grid is show. So, I assume that I have to extends AdvancedDataGrid and overwrite some methods. Does anybody know where I have to start? Any examples?

• DataGridCheckBoxColumn immediate binding

  - by Johan Zell

  Hi. I'm using the WPF Toolkit Datagrid and have one column which is a DataGridCheckBoxColumn bound to a bool property on my ViewModel. My problem is that I wan't the property to get it's value updated immediately when the user checks or unchecks the checkbox. Now you have to navigate away from the cell in order to have the property updated. It's a checkbox. It can't be in the middle of editing like a textbox can... Any help would be appreciated. /J

• Excel 2003 - ADDRESS() function issues

  - by hairdresser-101

  I finally thought I had found a way to acutally use excel productively but the code that I followed does not appear to work. I'm thinking that the code is very limited and can't do what I want but I thought I'd ask to confirm - maybe it is my function that is the problem. I want to calculate the sum of a row of values for the previous month based on how many days we are into this month (i.e. It is the 20th of April so I want to sum the first 20 days of March to compare against.) =SUM(G4:ADDRESS(ROW(),7+$BR$3,4)) I basically want to SUM(G4:AA4) and have used the address function to return the cell reference AA4 by taking G4 and adding 20 to the column count. ADDRESS(ROW(),7+$BR$3,4) This successfully returns AA7 as expected HOWEVER, when I try to use the returning value in the SUM() function it throws an error... Am I not able to use this reference in my calculation?

• Can't get NSDate to work correctly

  - by John

  Hello, having a strange issue, must be something I'm just not seeing. I set up a variable in the .h NSDate *checkIn; @property (nonatomic, retain) NSDate *checkIn; I'm setting a variable to todays date in the initWithNibName: checkIn = [NSDate date]; I also did synthesized it as well. Now later on in my program I use it to build a tablecell with the following line cell.textLabel.text = [dateFormatter stringFromDate:checkIn]; This line kills the simulator, BAD_EXEC. If I put in a checkIn = [NSDate date]; above it, it works fine. So I'm thinking the variable isn't being stored from when I set it in the initWithNibName: Not sure why though, as my strings I do the same way are all working fine from method to method. What am I missing?

• ASP.NET: CSS friendly calendar control

  - by pbz

  I'm using the built-in Calendar control. It works, but in a few places the way the HTML is rendered is broken or not CSS-friendly and unfortunately cannot be changed (it's hard coded). I was hoping they would fix this in .NET 4.0, but as far as I can tell the Calendar control hasn't been changed at all. Also, as far as I know, there's no CSS adapter for the Calendar control. So, I would need a control that would: Allow me to customize the content of each cell (like OnDayRender works) Allow me to assign CSS classes to any HTML it may render Not render anything automatically that cannot be turned off, except layout code No auto-postback or auto-JS code (I can handle these by hand using simple links or custom JS calls) Basically a simple calendar view control that would give me full rendering control. What would you recommend? Thanks!

• Table Disobeys W3C Box Model, Ie8 Ignores Fixed Table Width !

  - by Axel Myers

  Hi, I'm having hard time with tables and column widths. Update: I'm using XHTML Strict 1.0. The page is: http://www.pro-turk.net/try The first problem I have is, I have a column with a fixed width of 100px and 4px padding, but it disobeys my padding depending on the value. The column width (as the distance between two borders according to W3C Box Model) is 156 px even if padding is 0 or 4. Only the position of the text changes. According to W3C Box Model ( available at www.pro-turk.net/box_model.png ), borders and paddings aren't included in WIDTH attribute, so why does it render wrongly ? The second problem is, when you look the page I gave with IE8, the first cell in the second row has 150px fixed width, but ie shows it about 50% of the total table width regardless of what i say.

• IUNavigationController loading more viewControllers

  - by Goods

  Not a Noob as yesterday, but still green. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I have a 'Learn More' button on the current xib. I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Im thinking it has to do with the Navigation Controller? Do I need to import the navigationcontroller to every ViewControllerSubclass I make? Thanks.

• cfgrid boolean column as Yes/No

  - by Gene R

  I have a boolean type column in an html cfgrid. The data is stored in the database as 1/0 and is returned from CF as such. I want the user to see Yes/No instead of 1/0. I tried QuerySetCell, and couldn't get it to work. The form is editable, when you double click the cell, the checkboxes show and it updates as it should. The only issue is the display. <cfform> <cfgrid name="blah" format="html" bind="mycfccall" selectmode="edit"> <cfgridcolumn name="bitCol" header="Is it" width="75" type="boolean"> </cfgrid> </cfform> Thanks in advance...

• Evaluation of jQuery function variable value during definition of that function

  - by thesnail

  I have a large number of rows in a table within which I wish to attach a unique colorpicker (jQuery plugin) to each cell in a particular column identified by unique ids. Given this, I want to automate the generation of instances of the colorpicker as follows: var myrows={"a","b","c",.....} var mycolours={"ffffff","fcdfcd","123123"...} for (var i=0;i<myrows.length;i++) { $("#"+myrows[i]+"colour").ColorPicker({flat: false, color: mycolours[i], onChange: function (hsb, hex, rgb) { $("#"+myrows[i]+"currentcolour").css('backgroundColor', '#' + hex); } }); Now this doesn't work because the evaluation of the $("#"+myrows[i]+"currentcolour") component occurs at the time the function is called, not when it is defined (which is want I need). Given that this plugin javascript appends its code to the level and not to the underlying DOM component that I am accessing above so can't derive what id this pertains to, how can I evaluate the variable during function declaration/definition? Thanks for any help/insight anyone can give. Brian.

• Modify Hyperlinkfield text in Gridview

  - by JohnG

  I am stumped on this one. I want to modify the text in a Hyperlinkfield of Gridview after the data is bound to it. I found similar code to this on msdn and I can't get it to work. protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { e.Row.Cells[2].Text = e.Row.Cells[2].Text + "random text"; } I also tried similar code in the Page_PreRender event with no luck. I have also tried calling DataBind() before this one line of code with no help. I always just get "random text" in the cell without the data from the DB. Thanks

• Flex 4 how to layout spark controls in an html table type way

  - by Amy

  I have a group of controls and I want to organize them in a table like fashion. I want 1 row and 6 columns. Col 1,3,4,5,6 should all auto size to the contents and col 2 should take up the remaining available space. When the size of the group changes, only col2 width should change. I also want to be able to set the alignment of each cell. How can I do this in flex 4? I found a reference to mx:constraintColumns but this seems to be used with the canvas and in flex 4 adobe suggests not using canvases. Is there something similar in flex 4? I'm looking for something along the lines of Grid/Grid.ColumnDefinitions in silverlight.

• Text code decoding

  - by Diana Villafane

  Hello. I am an English/Spanish Spanish/English translator. I have been given a job where I have to translate Spanish text messages sent from cell phones. Some of them are in code. I assume each set of figures represents a letter. Is there any website where I can find information on how to decipher the code? For instance, the first message says: ‘0x69 ox61 0x6e 0x70 0x72 0x2e 0x6e 0x65 0x74 0x2f 0x3f 0x64 0x34 0x39 0x31 0x66 0x30 0x37 0x38 0x35 0x35 0x32 0x39 0x62 0x36 0x31 0x31 0x00 Thank you for any help you provide.

• How much difference you find between scrollview offset and contentview offset of table?

  - by neha

  Hi all, In my application, I want to detect the end of the entire table with scrollview. Since there're no sections in my scrollview, I'm using noOfRows*rowHeight to reach the end. I'm using scrollview.contentOffset.y to detect the y offset, but this contentOffset isn't matching the multiplication result i.e. I have 20 rows and with height as 250. So it comes as 5000, but my scrollview.offset.y at the end of last cell is nearly about 4650. What's this difference? Thanx in advance.

• Evenly distribute items on the screen

  - by abolotnov

  I am trying to solve this little puzzle (the algorithm): I have N image icons and I want to distribute them evenly on users screen. Say, I put them in a table. If there is one image, there will be one cell in a table. If two - one row with two columns, if three - one row and three columns, if four - two rows, two columns... and so on until row space is gone and since then the table should only grow in columns without adding extra rows. I'm trying to figure an algorithm for this and perhaps this is something that has a solution already somewhere? My attempt is so far something like this: obtain_max_rows() obtain_visible_columns() if (number_of_pictures > max_rows*max_columns) { columns = roundup(number_of_pictures/max_rows) for(max_rows){generate row;for columns{generate column}} } else { **here comes to trouble...** } This logic is bit silly though - it somehow needs to think cases where there are 12 pictures on first screen and 2 on the other trying to balance it say 8/6 or somehow like that.

• fieldset form with Table-like layout with CSS?

  - by Scott B

  I have an application in which I'm currently using a two column table in order to get accurate cell alignment of the left column labels/descriptions with the right column form fields. I'd like to convert it to css and use jQuery to expand/collapse specific sections. I've seen some jQuery libraries, the menu.js in particular. And they appear to all use list items for the markup. I'm OK with converting my table to UL/LI structure if that's what I need to do. Just looking for some advice.

• Why does overflow:hidden not work in a <td>?

  I've got a table cell that I would always like to be a particular width. However, it doesn't work with large strings of unspaced text. Here's a test case: <html><body> <table><tbody><tr> <td style="border: solid green 1px; width:200px; overflow:hidden;"> This_is_a_terrible_example_of_thinking_outside_the_box. </td> </tr></tbody></table> </body></html> How do I get the text to be cut off at the edge of the box, rather than having the box expanded?

• Rails Nested Attributes, Relationship for Shared or Common Object

  - by SooDesuNe

  This has to be a common problem, so I'm surprised that Google didn't turn up more answers. I'm working on a rails app that has several different kinds of entities, those entities by need a relation to a different entity. For example: Address: a Model that stores the details of a street address (this is my shared entity) PersonContact: a Model that includes things like home phone, cell phone and email address. This model needs to have an address associated with it DogContact: Obviously, if you want to contact a dog, you have to go to where it lives. So, PersonContact and DogContact should have foreign keys to Address. Even, though they are really the "owning" object of Address. This would be fine, except that accepts_nested_attributes_for is counting on the foreign key being in Address to work correctly. What's the correct strategy to keep the foreign key in Address, but have PersonContact and DogContact be the owning objects?

• Persisting a single UISearchBar instance across 4 separate UITableViews

  - by Jacob Relkin

  Hi fellas, I'm in the midst of an iPhone app that needs to have 4 separate UITableView objects sharing access to one UISearchBar in the first section and first row of the aforementioned UITableView objects. I have tried to offset the UITableView's frame by 44 pixels, then adding the search bar as a subview of my UIViewController's view. That works, but I cannot use the table index to scroll up to the search bar, since it is not a cell in the tableview. I need to have the search bar in the table view itself. My goal is to have the same UISearchBar in the first section of multiple tableviews. Thanks so much.

• Get positions for NAs only in the "middle" of a matrix column

  - by Abiel

  I want to obtain an index that refers to the positions of NA values in a matrix where the index is true if a given cell is NA and there is at least one non-NA value before and after it in the column. For example, given the following matrix [,1] [,2] [,3] [,4] [1,] NA 1 NA 1 [2,] 1 NA NA 2 [3,] NA 2 NA 3 the only value of the index that comes back TRUE should be [2,2]. Is there a compact expression for what I want to do? If I had to I could loop through columns and use something like min(which(!is.na(x[,i]))) to find the first non-NA value in each column, and then set all values before that to FALSE (and the same for all values after the max). This way I would not select leading and trailing NA values. But this seems a bit messy, so I'm wondering if there is a cleaner expression that does this without loops.

• same flash file (.swf) downloaded multiple times on a page

  - by Gunjan

  I have a page that has a table with each row corresponding to an audio file. The last cell in each row embeds a simple flash audio player. The problem is that the flash file for the player is being downloaded for each row separately and as soon as rows go beyond 40-50 it crashes the browser. I tried using different players (1pixelout, flash-mp3-player) and the problem is still there, so its not a player specific issue. Is there any way to cache the player so that it is only downloaded once?
