  • How to display an HTML email for preview on a webpage?

    - by Andrew
    I am trying to display a "preview" of an HTML email. I have the HTML in my database and now I need to render it in an iframe, or popup window or something. I am trying to inject the html into a div tag on the page, but it won't display anything. Here is the problem I am running into (I have nested HTML tags): <html> <body> <h1>My page</h1> <div id="email-body"> <html> <body> <p>email</p> </body> </html> </div> </body> </html>

  • How to get Word 2003 to make my print layout go from left to right?

    - by Shaul
    My copy of MS Word 2003 was installed on my computer with the locale set to Israel, so among other things my Normal.dot template was set up for right-to-left. I managed to fix most of the Hebrew support things so that I am working in English by default now. The only thing I haven't found a cure for is how to make the "print layout" view also go from left to right; as things are, the page flow always appears from right to left, even in English documents - IOW, page 1 appears on the right of page 2, as shown below. I can't see any obvious option to change this. How do I do it?

  • How to use jasper reports to print something only on the first page ?

    - by Harsha
    How to use jasper reports to print something only on the first page. I am using jasper reports for printing invoices and only on the 1st page I need to print the Remit Payment To section with the address following it. Customer address is also present there. The way it is currently designed is that this goes into pageFooter section and we use printWhenExpression(PAGE_NUMBER = 1) so that this only gets printed on the 1st page of the invoice. But the downside of this approach is that the jasper engine reserves the size equivalent of the page footer on all the other pages (1..n) of the invoice. So we are able to use only about 2/3 rd of all pages. Remaining 1/3rd page which is for page footer is blank for all pages except the 1st page. This increases the number of pages. Any ideas for fixing this issue?

  • Why is a report, in SSRS, when viewed in preview mode looks different when viewed in print layout mo

    - by Dean
    I have a report that was originally built in report builder and then imported into Visual Studio to add some other formating to it. The report has a header and a body section. In the body section there is a column that shows commission and the commission is subtotaled for each sales person. There is a page break for each sales person as well. When I preview the report, the subtotal appears as it should for each sales person, but when I either look at it in print layout mode or send it to the printer, the subtotal appears in the body section of the next page, which is the next sales person. Why is it behaving like this and how can I fix this? Thanks.

  • How can you prevent an individual window being captured by Print-Screen?

    - by John
    I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. I am not looking to fix the problem, but replicate it! Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

  • Should one use PHP to print all of a page's HTML?

    - by Mala
    Hi So I've always developed PHP pages like this: <?php goes at the top, ?> goes at the bottom, and all the HTML gets either print()ed or echo()ed out. Is that slower than having non-dynamic html outputted outside of <?php ?> tags? I can't seem to find any info about this. Thanks! --Mala UPDATE: the consesus seems to be on doing it my old way being hard to read. This is not the case if you break your strings up line by line as in: print("\n". "first line goes here\n". "second line goes here\n". "third line"); etc. It actually makes it a lot easier to read than having html outside of php structures, as this way everything is properly indented. That being said, it involves a lot of string concatenation.

  • globals and locals in python exec()

    - by hawkettc
    Hi, I'm trying to run a piece of python code using exec. my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(object): a_ref = A """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env which results in the following output locals: {'A': <class 'A'>} A: <class 'A'> Traceback (most recent call last): File "python_test.py", line 16, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 8, in <module> File "My Code", line 9, in B NameError: name 'A' is not defined However, if I change the code to this - my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(A): pass """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env then it works fine - giving the following output - locals: {'A': <class 'A'>} A: <class 'A'> {'A': <class 'A'>, 'B': <class 'B'>} Clearly A is present and accessible - what's going wrong in the first piece of code? I'm using 2.6.5, cheers, Colin * UPDATE 1 * If I check the locals() inside the class - my_code = """ class A(object): pass print 'locals: %s' % locals() print 'A: %s' % A class B(object): print locals() a_ref = A """ global_env = {} local_env = {} my_code_AST = compile(my_code, "My Code", "exec") exec(my_code_AST, global_env, local_env) print local_env Then it becomes clear that locals() is not the same in both places - locals: {'A': <class 'A'>} A: <class 'A'> {'__module__': '__builtin__'} Traceback (most recent call last): File "python_test.py", line 16, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 8, in <module> File "My Code", line 10, in B NameError: name 'A' is not defined However, if I do this, there is no problem - def f(): class A(object): pass class B(object): a_ref = A f() print 'Finished OK' * UPDATE 2 * ok, so the docs here - http://docs.python.org/reference/executionmodel.html 'A class definition is an executable statement that may use and define names. These references follow the normal rules for name resolution. The namespace of the class definition becomes the attribute dictionary of the class. Names defined at the class scope are not visible in methods.' It seems to me that 'A' should be made available as a free variable within the executable statement that is the definition of B, and this happens when we call f(), but not when we use exec(). This can be more easily shown with the following - my_code = """ class A(object): pass print 'locals in body: %s' % locals() print 'A: %s' % A def f(): print 'A in f: %s' % A f() class B(object): a_ref = A """ which outputs locals in body: {'A': <class 'A'>} A: <class 'A'> Traceback (most recent call last): File "python_test.py", line 20, in <module> exec(my_code_AST, global_env, local_env) File "My Code", line 11, in <module> File "My Code", line 9, in f NameError: global name 'A' is not defined So I guess the new question is - why aren't those locals being exposed as free variables in functions and class definitions - it seems like a pretty standard closure scenario.

  • Why wont numpy matrix let me print its rows?

    - by uberjumper
    Okay this is probably a really dumb question, however its really starting to hurt. I have a numpy matrix, and basically i print it out row by row. However i want to make each row be formatted and separated properly. >>> arr = numpy.matrix([[x for x in range(5)] for y in range(5)]) >>> arr matrix([[0, 1, 2, 3, 4], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4]]) Lets say i want to print the first row, and add a '|' between each element: >>> '|'.join(map(str, arr[0,])) '[[0 1 2 3 4]]' Err... >>> '|'.join(map(lambda x: str(x[0]), arr[0])) '[[0 1 2 3 4]]' I am really confused by this behavior why does it do this?

  • Scroll to a text position in Javascript

    - by Andy
    I have a real-time HTML editor, with a textarea on the left for code entry, and a 'preview' DIV on the right to contain the preview of the code entered. At the moment, when editing the code in the left pane, the preview just sits where it is, so often the part of the code you're editing is not in the visible area of the preview (especially when images are involved). My question is how do I make the preview scroll to show the part of the code that's currently being edited? Here is the page I have so far: http://www.caerphoto.com/rtedit.html You'll notice in the source I have a (currently unused) matchPreview() function that tries to match the scroll position of the preview based on the scroll position of the textarea, but obviously if images or large text are involved the two panes no longer match.

  • how to load files in python

    - by Alvaro
    I'm fairly new to python and would like some help on properly loading separate files. My codes purpose is to open a given file, search for customers of that file by the state or state abbreviation. However, i have a separate function to open a separate file where i have (name of state):(state abbreviation) Thanks. def file_state_search(fileid, state): z=0 indx = 0 while z<25: line=fileid.readline() data_list = ("Name:", "Address:", "City:", "State:", "Zipcode:") line_split = line.split(":") if state in line: while indx<5: print data_list[indx], line_split[indx] indx = indx + 1 elif state not in line: z = z + 1 def state_convert(fileid, state): line2=in_file2.readline() while state in line2: print line2 x=1 while x==1: print "Choose an option:" print print "Option '1': Search Record By State" print option = raw_input("Enter an option:") print if option == "1": state = raw_input("Enter A State:") in_file = open("AdrData.txt", 'r') line=in_file.readline() print in_file2 = open("States.txt", 'r') line2=in_file2.readline() converted_state = state_convert(in_file2, state) print converted_state state_find = file_state_search(in_file, state) print state_find x=raw_input("Enter '1' to continue, Enter '2' to stop: ") x=int(x) By the way, my first import statement works, for whatever reason my second one doesn't. Edit: My question is, what am i doing wrong in my state_convert function.

  • How to automatically print the contents of a folder in OS X?

    I would like to be able to set up a folder on my Mac, where I could dump files and have them be automatically sent to the default printer. This way I would be able to print files at home when I'm not physically at home, using something like Dropbox. It wouldn't have to be real-time; i.e., a scheduled job that checks the folder every so often would be acceptable. What's the easiest approach? Automator? Applescript? Cron job?

  • Java: Switch statements with methods involving arrays

    - by Shane
    Hi guys I'm currently creating a program that allows the user to create an array, search an array and delete an element from an array. Looking at the LibraryMenu Method, the first case where you create an array in the switch statement works fine, however the other ones create a "cannot find symbol error" when I try to compile. My question is I want the search and delete functions to refer to the first switch case - the create Library array. Any help is appreciated, even if its likely from a simple mistake. import java.util.*; public class EnterLibrary { public static void LibraryMenu() { java.util.Scanner scannerObject =new java.util.Scanner(System.in); LibraryMenu Menu = new LibraryMenu(); Menu.displayMenu(); switch (scannerObject.nextInt() ) { case '1': { System.out.println ("1 - Add Videos"); Library[] newLibrary; newLibrary = createLibrary(); } break; case '2': System.out.println ("2 - Search Videos"); searchLibrary(newLibrary); break; case '3': { System.out.println ("3 - Change Videos"); //Change video method TBA } break; case '4': System.out.println ("4 - Delete Videos"); deleteVideo(newLibrary); break; default: System.out.println ("Unrecognized option - please select options 1-3 "); break; } } public static Library[] createLibrary() { Library[] videos = new Library[4]; java.util.Scanner scannerObject =new java.util.Scanner(System.in); for (int i = 0; i < videos.length; i++) { //User enters values into set methods in Library class System.out.print("Enter video number: " + (i+1) + "\n"); String number = scannerObject.nextLine(); System.out.print("Enter video title: " + (i+1) + "\n"); String title = scannerObject.nextLine(); System.out.print("Enter video publisher: " + (i+1) + "\n"); String publisher = scannerObject.nextLine(); System.out.print("Enter video duration: " + (i+1) + "\n"); String duration = scannerObject.nextLine(); System.out.print("Enter video date: " + (i+1) + "\n"); String date= scannerObject.nextLine(); System.out.print("VIDEO " + (i+1) + " ENTRY ADDED " + "\n \n"); //Initialize arrays videos[i] = new Library (); videos[i].setVideo( number, title, publisher, duration, date ); } return videos; } public static void printVidLibrary( Library[] videos) { //Get methods to print results System.out.print("\n======VIDEO CATALOGUE====== \n"); for (int i = 0; i < videos.length; i++) { System.out.print("Video number " + (i+1) + ": \n" + videos[i].getNumber() + "\n "); System.out.print("Video title " + (i+1) + ": \n" + videos[i].getTitle() + "\n "); System.out.print("Video publisher " + (i+1) + ": \n" + videos[i].getPublisher() + "\n "); System.out.print("Video duration " + (i+1) + ": \n" + videos[i].getDuration() + "\n "); System.out.print("Video date " + (i+1) + ": \n" + videos[i].getDate() + "\n "); } } public static Library searchLibrary( Library[] videos) { //User enters values to setSearch Library titleResult = new Library(); java.util.Scanner scannerObject =new java.util.Scanner(System.in); for (int n = 0; n < videos.length; n++) { System.out.println("Search for video number:\n"); String newSearch = scannerObject.nextLine(); titleResult.getSearch( videos, newSearch); if (!titleResult.equals(-1)) { System.out.print("Match found!\n" + newSearch + "\n"); } else if (titleResult.equals(-1)) { System.out.print("Sorry, no matches found!\n"); } } return titleResult; } public static void deleteVideo( Library[] videos) { Library titleResult = new Library(); java.util.Scanner scannerObject =new java.util.Scanner(System.in); for (int n = 0; n < videos.length; n++) { System.out.println("Search for video number:\n"); String deleteSearch = scannerObject.nextLine(); titleResult.deleteVideo(videos, deleteSearch); System.out.print("Video deleted\n"); } } public static void main(String[] args) { Library[] newLibrary; new LibraryMenu(); } }

  • How to read back and print text with newlines from a Python (Django) string with HTML?

    - by user1801486
    If someone types in a phrase, such as: I see you driving round town with the girl I love, and I’m like: haiku. (no blank lines between each line, but the text is written on three separate lines) into a text box on a web page, and then presses a button which is then stored in a database via Django, and that string is read back and printed on a page, how can I get it to print on an HTML page with the newlines still in the text? So instead of it being printed back as: I see you driving round town with the girl I love, and I’m like: haiku. It would print as: I see you driving round town with the girl I love, and I’m like: haiku. I know that if I use: (textarea)soAndSo.body(/textarea), this preserves the newlines that were in the file when the user typed it up originally. How can I get this same effect, but without having to use textarea boxes?

I have this working with javascript, the form is posted to a file named preview.php that iterates through the posted information. The script currently opens a new window. I would like instead to use jQuery to post the form to a modal window for previewing. Does anyone have any thoughts on how to do this? This is what I am currently using: <script language="JavaScript"> function preview(form) { form.target='_blank'; form.action='http://example.com/preview.php'; form.submit(); } </script> <input type="button" value="preview" onclick='preview(this.form)'>

  • Generating a python file

    - by fema
    Hi! I'm havin issues with python (imo python itself is an issue). I have a txt file, it contains a custom language and I have to translate it to a working python code. The input: import sys n = int(sys.argv[1]) ;;print "Beginning of the program!" LOOP i in range(1,n) {print "The number:";;print i} BRANCH n < 5 {print n ;;print "less than 5"} The wanted output looks exactly like this: import sys n = int(sys.argv[1]) print "Beginning of the program!" for i in range(1,n) : print "The number:" print i if n < 5 : print n print "less than 5" The name of the input file is read from parameter. The out file is out.py. In case of a wrong parameter, it gives an error message. The ;; means a new line. When I tried to do it, I made an array, I read all the lines into it, split by " ". Then I wanted to strip it from the marks I don't need. I made 2 loops, one for the lines, one for the words. So then I started to replace the things. Everything went fine until it came to the } mark. It finds it, but it can not replace or strip it. I have no more idea what to do. Could someone help me, please? Thanks in advance!

  • Filtering string in Python

    - by Ecce_Homo
    I am making algorithm for checking the string (e-mail) - like "E-mail addres is valid" but their are rules. First part of e-mail has to be string that has 1-8 characters (can contain alphabet, numbers, underscore [ _ ]...all the parts that e-mail contains) and after @ the second part of e-mail has to have string that has 1-12 characters (also containing all legal expressions) and it has to end with top level domain .com EDIT email = raw_input ("Enter the e-mail address:") length = len (email) if length > 20 print "Address is too long" elif lenght < 5: print "Address is too short" if not email.endswith (".com"): print "Address doesn't contain correct domain ending" first_part = len (splitting[0]) second_part = len(splitting[1]) account = splitting[0] domain = splitting[1] for c in account: if c not in "abcdefghijklmopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_.": print "Invalid char", "->", c,"<-", "in account name of e-mail" for c in domain: if c not in "abcdefghijklmopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_.": print "Invalid char", "->", c,"<-", "in domain of e-mail" if first_part == 0: print "You need at least 1 character before the @" elif first_part> 8: print "The first part is too long" if second_part == 4: print "You need at least 1 character after the @" elif second_part> 16: print "The second part is too long" else: # if everything is fine return this print "E-mail addres is valid" EDIT: After reproting what is wrong with our input, now I need to make Python recognize valid address and return ("E-mail adress is valid") This is the best i can do with my knowledge....and we cant use regular expressions, teacher said we are going to learn them later.
