  • Printing JTables without formatting of the original component

    - by EricR
    I'm writing an application which utilises tables which can be printed if the user so desires and I wish to print a JTable filled with data, except I haven't been able to find an option to remove the formatting; the printed tables looks like it does in the GUI (based on the system theme) which is making the table less readable and using excess ink. I wish to print the same data with clear formatting. Is there a way to do this straight from a JTable or is my best option simply to print to a file and have the use printer from there. Currently it functions through a viewer which gives the user some options for printing, and then it goes to the system's printer.

  • Program LED with just USB port

    - by LifeH2O
    I want to control LED with C# using only USB port. I don't want to attach any other device with USB. I just want to attach LED directly to USB port pins and program it (blink etc). How can i do that? I am new to hardware programming and it will be my first program. EDIT: I can do it already (blink LED) using printer port by attaching one led pin to data pin and other to ground. How can i do the same with USB port? My motherboard does not have a printer port. USB is the only option.

  • Printing complex widgets in Qt

    - by Jens
    I have a complex widget with tons of different subwidgets, e.g. subclasses of QLabel. I want to print this widget, but obviously I do not want to print the background, I want to print with differing text colors or have the style of frames slightly modified. As I do not really want to iterate through all subwidgets with a special "print" function, which I would need to attach to all widgets (how to add "print" to a QLabel?), I would like to use paintEvent. If I have a hierarchy MyWidget - derived from - some QWidget, I would like to insert a sublayer MyWidget - MyPrintWidget - some QWidget, where myPrintWidget::paintEvent would check, if the current print is going to the screen (thus call QWidget::paintEvent), else if we are printing to the printer, call some function MyPrintWidget::drawWidget instead. Is this the right way to print-enable a widget? How can I figure out in paintEvent, that I'm printing to a printer instead of the screen? Is there a good example of printing complex widgets?

  • Produce high-quality, custom-size thumbnails from Office documents on Windows?

    - by Edwin
    Hi, What do you think would be the best way to produce custom size image thumbnail from MS Office documents (doc, xls and ppt) on Windows with native code (means all means besides .NET/JAVA)? My current research result: IExtractImage COM. Problem: The size of the generated result is fixed and low quality, and you can't be sure all the source documents contain the thumbnails. Use a programmable virtual printer to print the specified page, and the printer must support image output, any good suggestion for this? What else would you suggest? thanks!

  • Print PDF from ASP.Net without preview

    - by nmiranda
    Hi, I've generated a pdf using iTextSharp and I can preview it very well in ASP.Net but I need to send it directly to printer without a preview. I want the user to click the print button and automatically the document prints. I know that a page can be sent directly to printer using the javascript window.print() but I don't know how to make it for a PDF. Edit: it is not embedded, I generate it like this; ... FileStream stream = new FileStream(Request.PhysicalApplicationPath + "~1.pdf", FileMode.Create); Document pdf = new Document(PageSize.LETTER); PdfWriter writer = PdfWriter.GetInstance(pdf, stream); pdf.Open(); pdf.Add(new Paragraph(member.ToString())); pdf.Close(); Response.Redirect("~1.pdf"); ... And here I am.

  • Creating a Non-Databound Report in Winforms

    - by Jon
    I am using Visual Studio 2008 and all the components that come with it as well as Infragisitics for Winforms. I need to design a label that will print to a label printer. None of the controls are databound and will most likely be set in code eg/Label.Text = "My Heading"; as there will be minimal information on the label. One piece of information is a barcode so I need the functionality to do that, I assume I can just set the font of the label to barcode and it will do its thing. Can I just add a Crystal Report to a form design it, set the label text properties in code, tell it what printer to print to and then call report.Print(); I've had a quick go and seems not as easy as I thought. Thanks

  • Identify a non-computer network device?

    - by Avilan
    I'm current working on a program that scans my network and discoveres computers and devices on the network. I use various operations to find data on the devices I discover, but want to distinguish the network devices from computers. And I'm wondering if anyone knows how I could do this? I looked a bit at SNMP, and tried connecting to my network printer, router and modem. But I seem to only be able to connect to the printer, neither the router or modem responds. Is there another way to identify what kind of a device an IP address belongs to?

  • Hiding "Print to file" in a Java print dialog

    - by Carl Smotricz
    I'm maintaining this Swing app that has a "print" option. Users need to be kept from interacting in any way with the underlying file system, but the print dialog offers "print to file" as one printer, and that of course allows selecting a directory and file from the file system. Is there a painless way to override/modify the print dialog to hide the "to file" printer from this dialog? I understand the API will let me do this piecemeal but I'd rather not have to re-create most of the dialog GUI and functionality to do this.

  • Max. # of printers allowed for google cloud print

    - by user1858673
    I intend to write an online shopping program using PHP. When the buyer completes an order I want to print the receipt to his/her printer using Google Cloud Print. For that I will need the buyer to shared his/her printer with my Google account. My questions are: 1. Is there an upper bound for the number of printers a Google account is allowed to print to? 2. Is there a daily upper bound for the number of print jobs a Google account is allow? Thanks for reading and thanks for the answers in advance.

  • Function which returns itself

    - by Juliet
    As a purely academic exercise (read "because I have no life"), I'm trying to write a function f which accepts another function g, executes g for its side effect, and returns itself. So I have this: let rec f g x = ignore(g x) fun y -> f g y F# complains: fun y -> f g y;; -------------^^^^^ C:\Users\Juliet\AppData\Local\Temp\stdin(8,14): error FS0001: Type mismatch. Expecting a 'a but given a 'b -> 'a The resulting type would be infinite when unifying ''a' and ''b -> 'a' If it works the way I intend, then I could write: let printer = f (printfn "%s") printer("this")("is")("so")("useless")("its")("awesome!") // prints: // this // is // so // useless // its // awesome Is it possible to write a function like this?

  • Printing python tkinter output

    - by Eric
    I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

  • Forward traffic between two VLANs.

    - by Michael
    I have a small network with two VLANs. One is our internal network for basic file sharing, etc and the other is a public wifi network for our customers. The internal network is configured as 192.168.1.x and the public wifi is 192.168.11.x. We have one printer at 192.168.1.50. I would like to be able to have that printer available to our customer at 192.168.11.50. I suspect it can be done with iptables, but I'm brand new to it and I just can seem to work out the syntax. Can anyone offer any help? Oh, this is all running on a wrt54g router running Tomato.

  • Best method to print using wpf 4

    - by user293545
    Howdy, I need to be able to print from my wpf application. I am just trying to print a transaction receipt. I have found that using PrintDialog pDialog = new PrintDialog(); pDialog.PrintVisual(new Receipt("transaction name","my store"), "documentTitle"); Does the trick very nicely. "Receipt() is a usercontrol that renders out the transaction details. How are you meant to do this? is this the correct way? what do I do if I dont know the printer that is going to be used? should I make the usercontrol only as wide as a thermal receipt printer? Any suggestions would be great!

  • C# Different class objects in one list

    - by jeah_wicer
    I have looked around some now to find a solution to this problem. I found several ways that could solve it but to be honest I didn't realize which of the ways that would be considered the "right" C# or OOP way of solving it. My goal is not only to solve the problems but also to develop a good set of code standards and I'm fairly sure there's a standard way to handle this problem. Let's say I have 2 types of printer hardwares with their respective classes and ways of communicating: PrinterType1, PrinterType2. I would also like to be able to later on add another type if neccessary. One step up in abstraction those have much in common. It should be possible to send a string to each one of them as an example. They both have variables in common and variables unique to each class. (One for instance communicates via COM-port and has such an object, while the other one communicates via TCP and has such an object). I would however like to just implement a List of all those printers and be able to go through the list and perform things as "Send(string message)" on all Printers regardless of type. I would also like to access variables like "PrinterList[0].Name" that are the same for both objects, however I would also at some places like to access data that is specific to the object itself (For instance in the settings window of the application where the COM-port name is set for one object and the IP/port number for another). So, in short something like: In common: Name Send() Specific to PrinterType1: Port Specific to PrinterType2: IP And I wish to, for instance, do Send() on all objects regardless of type and the number of objects present. I've read about polymorphism, Generics, interfaces and such, but I would like to know how this, in my eyes basic, problem typically would be dealt with in C# (and/or OOP in general). I actually did try to make a base class, but it didn't quite seem right to me. For instance I have no use of a "string Send(string Message)" function in the base class itself. So why would I define one there that needs to be overridden in the derived classes when I would never use the function in the base class ever in the first place? I'm really thankful for any answers. People around here seem very knowledgeable and this place has provided me with many solutions earlier. Now I finally have an account to answer and vote with too. EDIT: To additionally explain, I would also like to be able to access the objects of the actual printertype. For instance the Port variable in PrinterType1 which is a SerialPort object. I would like to access it like: PrinterList[0].Port.Open() and have access to the full range of functionality of the underlaying port. At the same time I would like to call generic functions that work in the same way for the different objects (but with different implementations): foreach (printer in Printers) printer.Send(message)

  • Introducing AutoVue Document Print Service

    - by celine.beck
    We recently announced the availability of our new AutoVue Document Print Service products. For more information, please read the article entitled Print Any Document Type with AutoVue Document Print Services that was posted on our blog. The AutoVue Document Print Service products help address a trivial, yet very common challenge: printing and batch printing documents. The AutoVue Document Print Service is a Web-Services based interface, which allows developers to complement their print server solutions by leveraging AutoVue's printing capabilities within broader enterprise applications like Asset Lifecycle Management, Product Lifecycle Management, Enterprise Content Management solutions, etc. This means that you can leverage the AutoVue Document Print Service products as part of your printing solution to automate the printing of virtually any document type required in any business process. Clients that consume AutoVue's Document Print Service can be written in any language (for example Java or .NET) as long as they understand Web Services Description Language (WSDL) and communicate using Simple Object Access Protocol (SOAP). The print solution consists of three main components, as described in the diagram below: a print server (not included in the AutoVue Document Print Service offering) that will interact with your application to identify the files that need to be printed, the printer to send each file, as well as the print options needed for each file (paper size, page orientation, etc), and collate the print job requests. The print server will also take care of calling the AutoVue Document Print Service to perform the actual printing. The AutoVue Document Print Services send files to a printer for printing. The AutoVue Document Print Service products leverage AutoVue's format- and platform agnostic technology to let you print/batch virtually any type of files, without requiring the authoring application installed on your machine. and Printers As shown above, you can trigger printing from your application either programmatically through automated business processes or manually through human interaction. If documents that need to be printed from your application are stored inside a content repository/Document Management System (DMS) such as Oracle Universal Content Management System (UCM), then the Print Server will need to identify the list of documents and pass the ID of each document to the AutoVue DPS to print. In this case, AutoVue DPS leverages the AutoVue VueLink integration (note: AutoVue VueLink integrations are pre-packaged AutoVue integrations with most common enterprise systems. Check our Website for more information on the subject) to fetch documents out of the document management system for printing. In lieu of the AutoVue VueLink integration, you can also leverage the AutoVue Integration Software Development Kit (iSDK) to build your own connector. If the documents you need to print from your application are not stored in a content management system, the Print Server will need to ensure that files are made available to the AutoVue Document Print Service. The Print Server could for example fetch the files out of your application or an extension to the application could be developed to fetch the files and make them available to the AutoVue DPS. More information on methods to pass on file information to the AutoVue Document Print Service products can be found in the AutoVue Document Print Service Overview documentation available on the Oracle Technology Network.

  • Cool a Computer with Toilet Water

    - by Jason Fitzpatrick
    When most people opt to use water cooling they put together tidy coolant reservoirs complete with ambient lighting and the like. This build involves a hole in the wall and the tank of a functioning toilet. The design, courtesy of Jeff Gagnon, is unconventional, but effective. Opposite of his wall-mounted PC is a bathroom. In that bathroom he has a coolant pump in the tank of the toilet. Using the toilet tank as a thermal sink he keeps the CPU at a nice chilly 66F. Hit up the link below for more pictures, including a peek inside his hacked together toilet-tank cooling rig.
