  • standard rectangle class

    - by Neil G
    I have a project that has a GUI (written in QT) and a command-line version. I made use of the rectangle class included in QT: QRect. I would like to break the command-line version's dependency on QT, so I need a drop-in rectangle class that supports intersection and union. I could write one, but I'd prefer including one if possible. Any ideas?

  • iPhone: Push TableViewController onto stack. Is this possible?

    - by Nic Hubbard
    I have a view which contains a UIButton. When this is clicked, it calls a method that loads another NIB. Now, normally, that nib would load a view onto the stack, and everything would be fine. But, I am trying to load a TableViewController, and all I get it errors. What is the proper method for loading a TableViewController and putting it on the top of the stack?

  • applescript for sqlite

    - by user1212108
    I have a Windows app called via Shell from MS Word that reads and writes to Sqlite. I'm porting it to Mac. On windows I have a batch file: SQLite3.exe pathtodb\databasename <sqlitecommands.txt This batch calls the Sqlite command line program, attachs the database, and reads the command from sqlitecommands.txt. The sqlitecommands is dynamically modified(by Word VBA) to read (Select) Write (Update) to/from the database. What is the format of an applescript to do the same thing in Mac OSX?

  • How do you check to see if a variable has changed every second or less in objective c?

    - by James
    I am using an if statement to check the value of a BOOLEAN when i click on a button. When the button is clicked if the value is false i want to display a UIActivityIndicator and if the value is true i want to push the new view. I can do this fine but i want the view to change automatically when the BOOLEAN Becomes true if the user has already clicked the button. So my question is how do you check to see if a value has changed everysecond or less?

  • Is Core Animation causing my subviews to call -drawRect for every single frame?

    - by mystify
    I made a nice UIView subclass which paints all its stuff in -drawRect:, because people said that's good. That view is a subview of another. This another view is beeing animated with Core Animation: It's scaled down, rotated and moved. However, I encountered this: -drawRect seems to get called trillion of times during animation, and performance sucks. Is that normal or did I do something wrong, probably?

  • Routing to a different URLs based on post type

    - by DanCake
    What would be the best way to set up my routes so different types of posts have different URLs? For example, regular posts are /posts/slug while featured posts are /featured/slug Both link to the same controller and action /posts/view/slug. I experimented with different ways of doing this but with little success. Currently my link params look something like the following: array('controller' => 'posts', 'action' => 'view', 'featured' ,$post['Post']['slug'])

  • Set background of UITableview in interface builder?

    - by Martin
    In iPhone I need to set the background view of a UITableview. From 3.2 SDK I can in code use something like: [self.tableView setBackgroundView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"mycustombackground.png"]]]; But how can I do the same in interface builder? It would be great if I could just set the background view directly in interface builder. But can't seem to find this property, where is it? Thanks!

  • Delphi / MySql : Problems escpaing strings

    - by mawg
    N00b here, having problems escaping strings. I used the QuotedStr() function - shouldn't that be enough. Unfortunately, the string that I am trying to quote is rather messy, but I will post it here in case anyone wants to paste it into WinMerge or KDiff3, etc. I am trying to store an entire Delphi form into the database, rather than into a .DFM file. It has only one field, a TEdit edit box. The debugger shows the form as text as 'object Form1: TScriptForm'#$D#$A' Left = 0'#$D#$A' Top = 0'#$D#$A' Align = alClient'#$D#$A' BorderStyle = bsNone'#$D#$A' ClientHeight = 517'#$D#$A' ClientWidth = 993'#$D#$A' Color = clBtnFace'#$D#$A' Font.Charset = DEFAULT_CHARSET'#$D#$A' Font.Color = clWindowText'#$D#$A' Font.Height = -11'#$D#$A' Font.Name = 'MS Sans Serif''#$D#$A' Font.Style = []'#$D#$A' OldCreateOrder = False'#$D#$A' SaveProps.Strings = ('#$D#$A' 'Visible=False')'#$D#$A' PixelsPerInch = 96'#$D#$A' TextHeight = 13'#$D#$A' object Edit1: TEdit'#$D#$A' Left = 192'#$D#$A' Top = 64'#$D#$A' Width = 121'#$D#$A' Height = 21'#$D#$A' TabOrder = 8'#$D#$A' end'#$D#$A'end'#$D#$A before calling QuotedStr() and ''object Form1: TScriptForm'#$D#$A' Left = 0'#$D#$A' Top = 0'#$D#$A' Align = alClient'#$D#$A' BorderStyle = bsNone'#$D#$A' ClientHeight = 517'#$D#$A' ClientWidth = 993'#$D#$A' Color = clBtnFace'#$D#$A' Font.Charset = DEFAULT_CHARSET'#$D#$A' Font.Color = clWindowText'#$D#$A' Font.Height = -11'#$D#$A' Font.Name = ''MS Sans Serif'''#$D#$A' Font.Style = []'#$D#$A' OldCreateOrder = False'#$D#$A' SaveProps.Strings = ('#$D#$A' ''Visible=False'')'#$D#$A' PixelsPerInch = 96'#$D#$A' TextHeight = 13'#$D#$A' object Edit1: TEdit'#$D#$A' Left = 192'#$D#$A' Top = 64'#$D#$A' Width = 121'#$D#$A' Height = 21'#$D#$A' TabOrder = 8'#$D#$A' end'#$D#$A'end'#$D#$A''' afterwards. The strange thing is that my complete command 'INSERT INTO designerFormDfm(designerFormDfmText) VALUES ("'object Form1: TScriptForm'#$D#$A' Left = 0'#$D#$A' Top = 0'#$D#$A' Align = alClient'#$D#$A' BorderStyle = bsNone'#$D#$A' ClientHeight = 517'#$D#$A' ClientWidth = 993'#$D#$A' Color = clBtnFace'#$D#$A' Font.Charset = DEFAULT_CHARSET'#$D#$A' Font.Color = clWindowText'#$D#$A' Font.Height = -11'#$D#$A' Font.Name = ''MS Sans Serif'''#$D#$A' Font.Style = []'#$D#$A' OldCreateOrder = False'#$D#$A' SaveProps.Strings = ('#$D#$A' ''Visible=False'')'#$D#$A' PixelsPerInch = 96'#$D#$A' TextHeight = 13'#$D#$A' object Edit1: TEdit'#$D#$A' Left = 192'#$D#$A' Top = 64'#$D#$A' Width = 121'#$D#$A' Height = 21'#$D#$A' TabOrder = 8'#$D#$A' end'#$D#$A'end'#$D#$A''");' executes in a MySql console, but not from Delphi, where I pass that command as parameter command to a function which ADOCommand.CommandText := command; ADOCommand.CommandType := cmdText; ADOCommand.Execute(); I can only assume that I am having problems escpaing sequences which contain single quotes (and QuotedStr() doesn't seem to escape backslahes(?!)) What am I doing that is obviously, glaringly wrong?

    When I am grabbing data from my table that require permissions, should all the permission be done there? Such as checking for an admin or if they can view the data (in MySQL)?
