NSMatrix bindings mayhem -


I want to use the NSMatrix so that a 6- day work for employees (columns) week (6 rows) Fwaiai, since NSTableView does not cell-to-cell drag-and-drop support, oh I have to instead use NSMatrix .

However, I want to use NSArray content for coke binding, NSMatrix .

If I have an employee, then there will be 6 items in my array. However, if I add another employee, then the data of the employee 1 also needs to be captured on the array index (0-2-4-6-8-10), and the data in employee 2 is a weird index (1 -3-5-7- 9-11).

If I want to remove Employee 1 now, then I have to remove 10,8,6,4,2,0 items in that order!

Yowza

Am I reading this right? Is anyone else related to this madness? Actually, my initial arguments were correct - that is, with the built-in array for the content, NSMatrix returns

That the material is from top to bottom to top, an array of 10 elements in 5x2 matrix will be kept with these indices: 

  0 1 2 3 4 5 6 7 8 9 >  
 so I pieces of a couple of code sharing with you ... for example,  [self insColAtIndex: self.matrix.numberOfColumns] a call to a new one with new items Mat In the X, the last column added with the  "X" on this result: 
 
  0 1 2 3 4 x 5 6 7 8 9x  
 < p> Any early-size  allocation with NSMatrix  to the desired height of the N rows with at least 1 column, here NSArrayController  a sub-classified  control in two ways  NSMatrix  and its content array organizations work together: 
    NSMatrix column inserted on index (zero based) - (zero) insColAtIn Dex: (NSInteger Index) {NSInteger colCount = self.matrix.numberOfColumns; If (index & lieutenant; 0; index; callback) returns; NSInteger rowCount = self.matrix.numberOfRows; [Self. Matrix adcomm]; (NSInteger i = 0; i & lt; rowCount; i ++) [self insert object: [[Anssiel light] Int] Aararanned object Index: Index + Kolkount * i + i]; } // Remove the NSMatrix column on the index (zero-based) - (zero) delColAtIndex: (NSInteger) index {NSInteger colCount = self.matrix.numberOfColumns; If (index  index = colCount) returns; NSInteger rowCount = self.matrix.numberOfRows; [Self. Remove matrix column: index]; (NSInteger i = rowCount-1; i & gt; = 0; i--) to (remove themselves Objektatarended object Index: Index + Colkount * i];}

I think I have a NSMutableIndexSet could be made with the array index hit insertObjects with an array of NSMatrix at once (: atArrangedObjectIndexes: and removeObjectsAtArrangedObjectIndexes: < / Code>), but it seemed more troublesome that it was worth it.

The code to insert / delete rows continuously with the array (much easier) Areas are left as) exercise for the reader; -)

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
