  • INI file reverse engineering

    - by Akshar Prabhu Desai
    I am maintaining a legacy application which prints product labels on packaging. The format of the label is stored in a INI file. I wanted to know if anyone has any hints about the meaning of this format. I have pasted a snippet here. {D1531,1000,1501|} {C|} {U2;0130|} {D1531,1000,1501|} {AX;+000,+000,+00|} {AY;+05,0|} {PC000;0922,0555,15,15,H,11,B|} {RC00;<FE/>LABELTITLE</FE>|} {PC001;0865,0555,15,15,H,11,B|} {RC01;<FE/>CURRENT</FE>|} {PC002;0796,0040,10,10,H,11,B|}

  • How can I "pack()" a printable Java Swing component?

    - by Jonas
    I have implemented a Java Swing component that implements Printable. If I add the component to a JFrame, and do this.pack(); on the JFrame, it prints perfect. But if I don't add the component to a JFrame, just a blank page is printed. This code gives a great printout: final PrintablePanel p = new PrintablePanel(pageFormat); new JFrame() {{ getContentPane().add(p); this.pack(); }}; job.setPrintable(p, pageFormat); try { job.print(); } catch (PrinterException ex) { System.out.println("Fail"); } But this code gives a blank page: final PrintablePanel p = new PrintablePanel(pageFormat); // new JFrame() {{ getContentPane().add(p); this.pack(); }}; job.setPrintable(p, pageFormat); try { job.print(); } catch (PrinterException ex) { System.out.println("Fail"); } I think that this.pack(); is the big difference. How can I do pack() on my printable component so it prints fine, without adding it to a JFrame? The panel is using several LayoutManagers. I have tried with p.validate(); and p.revalidate(); but it's not working. Any suggestions? Or do I have to add it to a hidden JFrame before I print the component?

  • Printdialog in multithreaded wpf window thrown TargetInvocationException

    - by Nils
    I have designed a multithreaded app, which is starting most windows in an dedicated thread like this: Thread newWindowThread = new Thread(new ThreadStart(ThreadStartingPoint)); newWindowThread.SetApartmentState(ApartmentState.STA); newWindowThread.IsBackground = true; newWindowThread.Start(); However, if in one of those window-in-own-thread I try to print something by simply calling PrintDialog pDialog = new PrintDialog(); bool? doPrint = pDialog.ShowDialog(); I get a TargetInvocationException - it does look like the PrintDialog does not reside in the same thread as my window. Is there any way to create a thread-agnostic (or "thread-save") PrinterDialog ?

  • How exactly do MbUnit's [Parallelizable] and DegreeOfParallelism work?

    - by BenA
    I thought I understood how MbUnit's parallel test execution worked, but the behaviour I'm seeing differs sufficiently much from my expectation that I suspect I'm missing something! I have a set of UI tests that I wish to run concurrently. All of the tests are in the same assembly, split across three different namespaces. All of the tests are completely independent of one another, so I'd like all of them to be eligible for parallel execution. To that end, I put the following in the AssemblyInfo.cs: [assembly: DegreeOfParallelism(8)] [assembly: Parallelizable(TestScope.All)] My understanding was that this combination of assembly attributes should cause all of the tests to be considered [Parallelizable], and that the test runner should use 8 threads during execution. My individual tests are marked with the [Test] attribute, and nothing else. None of them are data-driven. However, what I actually see is at most 5-6 threads being used, meaning that my test runs are taking longer than they should be. Am I missing something? Do I need to do anything else to ensure that all of my 8 threads are being used by the runner? N.B. The behaviour is the same irrespective of which runner I use. The GUI, command line and TD.Net runners all behave the same as described above, again leading me to think I've missed something. EDIT: As pointed out in the comments, I'm running v3.1 of MbUnit (update 2 build 397). The documentation suggests that the assembly level [parallelizable] attribute is available, but it does also seem to reference v3.2 of the framework despite that not yet being available. EDIT 2: To further clarify, the structure of my assembly is as follows: assembly - namespace - fixture - tests (each carrying only the [Test] attribute) - fixture - tests (each carrying only the [Test] attribute) - namespace - fixture - tests (each carrying only the [Test] attribute) - fixture - tests (each carrying only the [Test] attribute) - namespace - fixture - tests (each carrying only the [Test] attribute) - fixture - tests (each carrying only the [Test] attribute)

  • Need a fast programming language that can drive two printers

    - by Pete
    I have a rather unusual application that isn't working the way I need, and I hope someone here will have some suggestions or at least a direction to investigate. We have a museum exhibit that has a computer at the entrance driving two small receipt printers. There are two buttons on a console, wired to the left and right buttons of a disemboweled mouse. The two printers and associated buttons are for girls and boys, each button does a random selection from a database of names and prints a small ticket on the appropriate printer with a graphic image, a few words about the exhibit and the randomly chosen name. Conceptually all is well, but it hangs quite often. I got the project at the last minute, because the original designer got bogged down and couldn't deliver, so the exhibit's author asked me the day before opening, whether I could write something that would work. I did it in Word, since I am an experienced VBA programmer. Several other avenues I attempted first all lead to dead ends - one couldn't do graphics, another couldn't handle two printers, yet another couldn't change fonts and so on. The problem is that it simply isn't fast enough - Word can only drive one printer at a time and changing the active printer takes a long time. Not by office standards, where a second or two of delay before a printer starts working on your document is not an issue, but here I need more or less instant response. If kids press a button and nothing happens, they press it over and over until something does happen, resulting in maybe half a dozen commands being sent before the printer starts reacting. Sometimes it jams the program completely, since boys and girls will be pressing the two buttons simultaneously and Word locks up, and even when it doesn't jam, the printers then spit out a stream of tickets, making a mess. The kids start squabbling over which ticket is whose, pulling them out of the printers, snarling the paper tape, jamming the printer and generally making a mess of the whole affair, often necessitating the exhibit caretakers having to restart the computer and clear torn bits of paper out the printers. What I need is some sort of fast programming language that can drive two printers *-simultaneously-*, not the MSOffice claptrap of having to switch the active printer, that can react to both left and right mouse button click events, can print a small graphic image and can print in different font sizes and styles and. I don't need many, but it's not all in one typeface. Can anyone suggest what I might use for this? I don't even know if it's possible at all under Windows, whether the "single active printer" garbage is an Office artifact, or a Windows restriction. My little Commodore-64 twenty-five years ago had two printers attached to it and drove both simultaneously with no difficulties - it doesn't seem to me it should be such an impossible requirement today.

  • Maximum File Size and Pixels for Uploaded Business Documents

    - by webdevguy
    I am creating a php form that accepts an upload of business documents in a variety of formats .pdf, .doc, .tiff, .jpeg, etc. and I need to restrict the size of the files that are uploaded. It's trivial for me to restrict the file size, but I'm not sure if I should also restrict the max height/width, which are also available options. I will need to occasionally print these documents to 8.5 X 11inch paper and have them be legible, but don't really care if images come out. Should I restrict the pixels sizes or is that redundant with restricting the file size? If so, do you guys have a recommendations for max height/width for, say, a 5MB file size limit? I really have no idea what the relationship between pixel size and image size is or what the common pixel sizes are for scanned images. Also, what would be a reasonable size expectation for a legible print per page?

  • How to specify a web service URL within a Drupal module's simpletest?

    - by Matt V.
    I have a Drupal module that talks to a REST API on a separate server for user registration and authentication. The module runs on multiple sites which point to different servers which may run different versions of the REST API. Ideally, I'd like to be able to run each site against its own end-point, in case changes on the back end break things. Is there a way to dynamically specify a different end-point URL when running a test? Or do I have to edit the .test file for each site? I'm trying to keep the module's files as generic and flexible as possible. I guess I could have the .test file look for a .inc file that could override the URL, if needed for a particular site. Is there a better way though?

  • Automatically Word-Wrapping Text To A Print Page?

    - by sooprise
    I have some code that prints a string, but if the string is say: "Blah blah blah"... and there are no line breaks, the text occupies a single line. I would like to be able to shape the string so it word wraps to the dimensions of the paper. private void PrintIt(){ PrintDocument document = new PrintDocument(); document.PrintPage += (sender, e) => Document_PrintText(e, inputString); document.Print(); } static private void Document_PrintText(PrintPageEventArgs e, string inputString) { e.Graphics.DrawString(inputString, new Font("Courier New", 12), Brushes.Black, 0, 0); } I suppose I could figure out the length of a character, and wrap the text manually, but if there is a built in way to do this, I'd rather do that. Thanks!

  • Why is django.test.client.Client not keeping me logged in.

    - by Mystic
    I'm using django.test.client.Client to test whether some text shows up when a user is logged in. However, I the Client object doesn't seem to be keeping me logged in. This test passes if done manually with Firefox but not when done with the Client object. class Test(TestCase): def test_view(self): user.set_password(password) user.save() client = self.client # I thought a more manual way would work, but no luck # client.post('/login', {'username':user.username, 'password':password}) login_successful = client.login(username=user.username, password=password) # this assert passes self.assertTrue(login_successful) response = client.get("/path", follow=True) #whether follow=True or not doesn't seem to work self.assertContains(response, "needle" ) When I print response it returns the login form that is hidden by: {% if not request.user.is_authenticated %} ... form ... {% endif %} This is confirmed when I run ipython manage.py shell. The problem seems to be that the Client object is not keeping the session authenticated.

  • Word 2007 macros: is there an OnPrint event I can attach a macro to?

    - by notnot
    I'm looking to do a formatting check on word files before they get sent to the printer and it needs to be completely transparent to the user (no extra controls, just using the standard print options available through the UI). Is there an OnPrint or BeforePrint event, or something that can be used in that respect which I could attach a macro to, the same way I can with Open, Close, or Save? This feels like it should be simple... but those are famous last words. Thanks in advance, Rob

  • generate images with labels from a database

    - by Duncan Benoit
    hi there I need to have some images into my database, and the thing is that i need that images to have certain file names, dimensions and text on it. I know how to generate some images using the opencv lib, but this means that i need to install the lib and do just that job(which sounds as reinventing the wheel). Do you think is worth to do that or maybe you have a better idea? ps: the images are for testing stage of a software application, so i don;t need anything fancy or artistic.

  • Print/save full webpage as PDF

    - by Oliver
    I need a method to be able to print/save the current full webpage as a PDF. I know it can be done if I download a PDF printer and print to that; but I need it to be done without the user having to do anything other than click a button in a webpage. I can't do it via PHP as the page is all client side content, so I'm guessing an ActiveX component? Any ideas would be greatly appreciated! Many thanks

  • All parts of my Printable Swing component doesn't print

    - by Jonas
    I'm trying to do a printable component (an invoice document). I use JComponent instead of JPanel because I don't want a background. The component has many subcomponents. The main component implements Printable and has a print-method that is calling printAll(g) so that all subcomponents should be printed. But my subcomponents doesn't print. What am I missing? Does all subcomponents also has to implement Printable? import java.awt.BorderLayout; import java.awt.Dimension; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.GridLayout; import java.awt.print.PageFormat; import java.awt.print.Printable; import java.awt.print.PrinterException; import java.awt.print.PrinterJob; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; public class PPanel extends JComponent implements Printable { static double w; static double h; public PPanel() { this.setLayout(new BorderLayout()); this.add(new JLabel("Document Body"), BorderLayout.CENTER); this.add(new Header(), BorderLayout.NORTH); this.add(new Footer(), BorderLayout.SOUTH); } class Header extends JComponent { public Header() { this.setLayout(new BorderLayout()); this.add(new TopHeader(), BorderLayout.NORTH); this.add(new LowHeader(), BorderLayout.SOUTH); } } class TopHeader extends JComponent { public TopHeader() { this.setLayout(new BorderLayout()); JLabel companyName = new JLabel("Company name"); JLabel docType = new JLabel("Document type"); this.add(companyName, BorderLayout.WEST); this.add(docType, BorderLayout.EAST); } } class LowHeader extends JComponent { public LowHeader() { this.setLayout(new GridLayout(0,2)); JLabel col1 = new JLabel("Column 1"); JLabel col2 = new JLabel("Column 2"); this.add(col1); this.add(col2); } } class Footer extends JComponent { public Footer() { this.setLayout(new GridLayout(0,2)); JLabel addr = new JLabel("Address"); JLabel sum = new JLabel("Sum"); this.add(addr); this.add(sum); } } public static void main(String[] args) { final PPanel p = new PPanel(); PrinterJob job = PrinterJob.getPrinterJob(); job.setPrintable(p); try { job.print(); } catch (PrinterException ex) { // print failed } // Preview new JFrame() {{ getContentPane().add(p); this.setSize((int)w, (int)h); setVisible(true); }}; } @Override public int print(Graphics g, PageFormat pf, int page) throws PrinterException { if (page > 0) { return NO_SUCH_PAGE; } Graphics2D g2d = (Graphics2D)g; g2d.translate(pf.getImageableX(), pf.getImageableY()); w = pf.getImageableWidth(); h = pf.getHeight(); this.setSize((int)w, (int)h); this.setPreferredSize(new Dimension((int)w, (int)h)); this.doLayout(); this.printAll(g); return PAGE_EXISTS; } }

  • Can I test for the end of the content of a text/plain file with Selenium or javascript?

    - by fool4jesus
    I have a page that results in a text/plain file being displayed in the browser that looks like this: ... Admin Site Administration 2010-04-21 22:26:34 [email protected] Test Site Bob Smith 2010-04-21 22:27:09 [email protected] Admin Site Administration 2010-04-21 22:29:26 [email protected] I am trying to write a Selenium test against this that verifies the last line of the file has "[email protected]" at the end. How would you do this? I can't depend on the date/time as this is a login report that is constantly getting updated - all I want is to ensure that the last line ends with that email address. And I can't figure out how to do it using Selenium expressions, DOM, or XPath.

  • Print styles: How to ensure image doesn't span a page break

    - by notJim
    This is a problem I've had a few times, and I'm not sure how to deal with it. When writing a print stylesheet, is there a way to ensure that an image is always only on a single page. An example of the behavior I'm seeing is below: Page 1 | | | (text text text) | | (text text text) | | ________________ | | | Top of image | | |____________________| ------page break------ ____________________ Page 2 | | Rest of image | | | |________________| | | … | What I'd like Page 1 | | | (text text text) | | (text text text) | | | | | |____________________| ------page break------ ____________________ | ________________ | | | Full image | | | | | | | |________________| | | … | All those times I bitching about floats in LaTeX, and here I am asking for the same functionality... Can this be done? I'm not necessarily concerned about it working in all browsers, since this is often just a one-off document I'm writing to be turned into a PDF.

  • How to automate testing of a browser-based app?

    - by mawg
    If it were a windows program, I would use Auto it to automate testing. Is there something similar for browser-based apps? Nothing too complex, it should just allow scripting (preferable for me to macro-recording) to simulate human interaction with the browser, which means being able to identify fields of a form by name, inject text into some, simulate mouse-click on others, etc and then, after submitting a form, should be able to read text certain named controls, check the status of others (checked, radio group index, read-only, etc). While I do appreciate a full featured product, I don't appreciate a steep learning curve. so something as simple as the scripting of Auto It woudl be fine. I don't know if it makes a difference which browser is used, but I could live with MSIE 6 or higher (maybe 7 or higher at a push).

  • Invisible Delimiter for Strings in HTML

    - by noah
    I need a way to identify certain strings in HTML markup. I know what the strings are, but it is possible that they could be substrings of other strings in the document. To find them, I output a special delimiter character (currently using \032). On page load, we go through the HTML and record the location of the strings, and remove the delimiter. Unfortunately, most browsers show the delimiter character until we can find and remove them all. I'd like to avoid that if possible. Is there a character or string that will be preserved in the HTML content (so a comment wont work) but wont be visible to the user? It also needs to be something that is fairly unlikely to appear next to a string, so something like &nbsp; wouldn't work either. EDIT: Sorry, I forgot to mention that the strings will be in attributes, so any sort of tag wont work.
