  • How to get only a filename (not full path) into $1, using the PERL, regular expressions

    - by Scott
    I want to keep only the filenames (not full paths) and add the filename to some bbcode. Here is the HTML to be converted: <a href=/path/to/full/image.jpg rel=prettyPhoto><img rel=prettyPhoto src=/path/to/thumb/image.jpg /></a> Notice I cannot have rel="foo" (no double quotes).. Here is what I have in PERL, to perform the conversion: s/\<a href=(.+?)\ rel=prettyPhoto\>\<img rel=prettyPhoto src=(.+?) \/>\<\/a\>/\[box\]$1\[\/box\]/gi; This converts the HTML to: [box]/path/to/image.jpg[/box] But this is what I want as a result: [box]image.jpg[/box] The HTML must remain the same. So how do I change my PERL so that $1 contains only the filename?

  • Is there any tips for minimising access to a public page without login?

    - by alex
    I have a page that is just a non interactive display for a shop window. Obviously, I don't link to it, and I'd also like to avoid people stumbling across it (by Google etc). It will always be powered by Chrome. I have thought of... Checking User Agent for Chrome Ensuring resolution is 1920 x 1080 (not that useful as it is a client side check) Banning under robots.txt to keep Google out of it Do you have any more suggestions? Should I not really worry about it?

  • Free Tool(s) / Tips to assist me in filling out forms on Win7?

    - by MedicineMan
    I am doing some web development on some long forms. There are many fields for me to fill out to get through the form. Instead of typing out the same things every time (contact information, address, business information) I'm hoping there is some tool out there / combination of tools that will assist me in filling this out. Requirements: I am doing development / testing in FF, IE, and Chrome on a Win 7 system, so the tool would leverage one of those platforms. Oh yeah, one more thing: It's got to be free and lightweight, otherwise, I'd rather just type out responses to the form fields.

  • Tips for measuring the parallelism speed-up in multi-core development.

    - by fnCzar
    I have read many of the good questions and answers around multi-core programming how-tos etc. I am familiar with concurrency, IPC, MPI etc but what I need is advice on how to measure speed-up which will help in making a business case of spending the time to write such code. Please don't answer with "well run it with single-core code then multi-core code and figure out the difference". This is neither a scientific nor a reliable way to measure performance improvement. If you know of tools that will do some of the heavy lifting please mention them. Answers pertaining to methodology will be more fitting but listing tools is ok as well.

  • Does anybody have any tips for managing polymorphic nested resources in Rails 3?

    - by Ryan
    in config/routes.rb: resources posts do resources comments end resources pictures do resources comments end I would like to allow for more things to be commented on as well. I'm currently using mongoid (mongomapper isn't as compatible with rails3 yet as I would like), and comments are an embedded resource (mongoid can't yet handle polymorphic relational resources), which means that I do need the parent resource in order to find the comment. Are there any elegant ways to handle some of the following problems: in my controller, I need to find the parent before finding the comment. if params[:post_id] parent = Post.find(params[:post_id] else if params[:picture_id] parent = Picture.find(params[:picture_id] end which is going to get messy if I start adding more things to be commentable also url_for([comment.parent,comment]) doesn't work, so I'm going to have to define something in my Comment model, but I think I'm also going to need to define an index route in the Comment model as well as potentially an edit and new route definition. There might be more issues that I have to deal with as I get further. I can't imagine I'm the first person to try and solve this problem, are there any solutions out there to make this more manageable?

  • Read char from txt file in C++

    - by Jack in the Box
    I have a program that will read the number of rows and columns from a txt file. Also, the program has to read the contents of a 2D array from the same file. Here is the txt file 8 20 * * *** *** 8 and 20 are the number of rows and columns respectively. The spaces and asterisks are the contents of the array, Array[8][20] For example, Array[0][1] = '*' I did make the program reading 8 and 20 as follow: ifstream myFile; myFile.open("life.txt"); if(!myFile) { cout << endl << "Failed to open file"; return 1; } myFile >> rows >> cols; myFile.close(); grid = new char*[rows]; for (int i = 0; i < rows; i++) { grid[i] = new char[cols]; } Now, how to assign the spaces and the asterisks to to the fields in the array? I hope you got the point.

  • How to have the controller change its behavior depending on the view?

    - by Ian Boyd
    If from one view a user enters some invalid data, e.g.:     E-mail: [email protected]     then i want the controller to: not place the data into the model color the text box reddish not allow the user to save But it's possible that if the user enters the same invalid data in a different view i want the controller to: place the data into the model color the text box reddish allow the user to save But it's possible that if the user enters the same invalid data in a different view i want the controller to: place the data into the model color the text box bluish allow the user to save And it's possible that another view will: place the data into the model leave the text box uncolored allow the user to save And it's possible that another view will: auto-correct the data, placing it into the model color the text-box reddish allow the user to have And it's possible for another view to: auto-correct the data, placing it into the model update the view with the new data color the text-box bluish allow the user to save [ad infinitum] Without using n-controllers for n-views, how do i do this?

  • Activate WPF command based on TextBox value

    - by zendar
    This is MVVM application. I have form and related view model class. There is TextBox, Button and ListBox on form. Button is bound to DelegateCommand that has CanExecute function. Idea is that user enters some data in text box, presses button and data is appended to list box. I would like to enable command (and button) when user enters correct data in TextBox. Things look like this now: CanExecute() contains code that checks if data in property bound to text box is correct. Text box is bound to property in view model UpdateSourceTrigger is set to PropertyChanged and property in view model is updated after each key user presses. Problem is that CanExecute() does not fire when user enters data in text box. It doesn't fire even when text box lose focus. How could I make this work?

    - by John M
    I am working on a Excel 2007 workbook that will contain a macro to save the current sheet (a template) as a PDF file (no problem) a Excel 97-2003 file (problem) When saving the Excel file a messagebox appears asking about "Defined names of formulas in this workbook may display different values when they are recalculated...Do you want Excel to recalculate all formulas when this workbook is opened?". The user can then select Yes/No and then the file will save. How do I disable the messagebox from appearing? The default answer would be 'No'. My code for saving: Sub saveAs_97_2003_Workbook(tempFilePath As String, tempFileName As String) Dim Destwb As Workbook Dim SaveFormat As Long 'Remember the users setting SaveFormat = Application.DefaultSaveFormat 'Set it to the 97-2003 file format Application.DefaultSaveFormat = 56 ActiveSheet.Copy Set Destwb = ActiveWorkbook Destwb.CheckCompatibility = False With Destwb .SaveAs tempFilePath & tempFileName & ".xls", FileFormat:=56 .Close SaveChanges:=False End With 'Set DefaultSaveFormat back to the users setting Application.DefaultSaveFormat = SaveFormat End Sub

    I am working on a custom CRM form with numerous checkboxes, organized by sections. I would like to implement a 'select all' feature to the form and am trying to understand how to format the JavaScript. My research thus far has pointed me to the possibility of using a FOR statement to iterate through all of the elements in the section I want to process, setting their values accordingly, but am unsure of which document.getElements ... method to utilize.

  • Is it possible to write a generic +1 method for numeric box types in Java?

    - by polygenelubricants
    This is NOT homework. Part 1 Is it possible to write a generic method, something like this: <T extends Number> T plusOne(T num) { return num + 1; // DOESN'T COMPILE! How to fix??? } Short of using a bunch of instanceof and casts, is this possible? Part 2 The following 3 methods compile: Integer plusOne(Integer num) { return num + 1; } Double plusOne(Double num) { return num + 1; } Long plusOne(Long num) { return num + 1; } Is it possible to write a generic version that bound T to only Integer, Double, or Long?
