• Visual studio 2008 Professional Edition acting weird

  - by Andres

  I have a weird situation on a winform project. I have user control (with 600 lines of code around) with a datagridview. I change de ColumnHeaderStyle of the font and save it. After I save the file I close it and open again, the changes were not saved (although the asterisk is dissapeared), because the ColumnHeaderStyle is back to the former value. This is driving me crazy because I cannot change any visual thing in the Designer. Any clue? Thanks in advance.

• How Should I Print Documentation from Google Code?

  - by peter.newhook

  Google does a decent job of documenting their API (like Closure http://code.google.com/closure/compiler/docs/overview.html) but I find it hard to read because it's broken into such short pages. I like to leaf through my docs and read it on paper. Has anyone found a good way to print from the documentation on Google Code. It could be a PDF, or even just a long page with lots of content. Please note, I'm not talking about the Wikis in the Open Source side of Google Code. I'm referring to the API docs published by Google.

• how to work with strings and integers as bit strings in python?

  - by Manuel

  Hello! I'm developing a Genetic Algorithm in python were chromosomes are composed of strings and integers. To apply the genetic operations, I want to convert these groups of integers and strings into bit strings. For example, if one chromosome is: ["Hello", 4, "anotherString"] I'd like it to become something like: 0100100100101001010011110011 (this is not actual translation). So... How can I do this? Chromosomes will contain the same amount of strings and integers, but this numbers can vary from one algorithm run to another. To be clear, what I want to obtain is the bit representation of each element in the chromosome concatenated. If you think this would not be the best way to apply genetic operators (such as mutation and simple crossover) just tell me! I'm open to new ideas. Thanks a lot! Manuel

• Data sync solution?

  - by user321088

  For some security issues I'm in an envorinment where third party apps can't access my DB. For this reason I should have some service/tool/script (dunno what yet... i'm open to the best option, still reading to see what I'm gonna do...) which enables me to generate on a regular basis(daily, weekly, monthly) some csv file with all new/modified records for a certain application. I should be able to automate this process and also export at any time a new file. So it should keep track for each application which records he still needs. Each application will need some data in some other format (csv/xls/sql), also some fields will be needed for some application and some aren't... It should be fairly flexible... What is the best option for me? Creating some custom tables for each application? Based on that extracting modified data?

• Getting website data into Adobe InDesign

  - by Magnus Smith

  I'd like our magazine team to be able to download website data in a file that Adobe InDesign can read. They can then import/open the file, make a few tweaks, and cut out a vast deal of repetitive manual labour (they currently use copy&paste for a few hours). After a brief Google I note that v2 of InDesign can import/export XML so perhaps that is my best bet? Are there any alternatives, and can anyone offer any advice on them? I am using a PC, and the magazine team are on Macs; testing will be tiresome I fear. The data we wish to format is fairly simple - a title followed by a short chunk of text (repeated about 50 times, say). I'll ask about importing images later. Thanks for your help. I will return to Google now, but it would be great if anyone can point me in a more specific direction first!

• MS Access Print Report using VBA

  - by LanguaFlash

  I have a very VBA intensive report. When I preview it everything is great but when I print it after previewing things go wacky. I have spent many hours narrowing down the possibilities and I have conclude with a certain level of confidence that it is a but in MS Access. Up to this point my method for printing reports was to open the report using docmd.openreport "report". I then use the docmd.printout command so that I can set the page range, collation etc. Is there a way to print a report directly and still be able to set options like page rage, collate etc without doing a preview first? Thanks, Jeff

• Opening Visual Studio created XAML in Expression Blend

  - by Jens A.

  I have created a console application using Visual Studio 2008. In a few cases, this application shows a WPF dialog. Now, the design view of Visual Studio is a little limited, so I'd like to edit this dialog using Expression Blend 3. Blend does not seem to have an option to load individual XAML files, and when I open my solution in Blend, only the XAML code is displayed when I try to edit the dialog. Edit: I've noticed, that no IntelliSense is available in the text view either. When I create a new WPF Project inside Blend, and copy my dialog there (overwriten MainWindows.xaml), I get a design view. What do I have to do to actually get a design view here? Thank! =) Edit: Header of my XAML file: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="QuantumAnalysis.Deployment.Activation.Checker.MainWindow" x:Name="Window" Title="MainWindow" HorizontalAlignment="Right" Width="600" SizeToContent="Height">

• Google Gadgets and external scripts

  - by Brandon Durham

  I'm trying to create my first custom Google Gadget to be used privately in my company's Google Sites intranet. Ideally I'd like to just show a thumbnail that the user can click that will open a modal window with the full video. This requires my including a couple of small JS libraries in my widget. For my widget I created this XML: <?xml version="1.0" encoding="UTF-8"?> <Module> <ModulePrefs title="Video Demos" /> <Content view="url" href="http://www.website.com/_gadgets/video.php"> </Content> </Module> The "video.php" page has simple HTML on it and includes two JS files for the modal window using but doesn't work. Are you not able to include external scripts like this? If not, what are my options here?

• Printing pdf without opening

  - by Marius

  Hello there, I want to open a PDF-print dialog (not regular browser dialog) without visually opening the document so that I can print a pdf without having the header and footer information from a regular webpage print. I know this is possible, because I have seen it in the past on a postal service website for printing postage labels, but cannot remember where. As far as I know, printing it from an iframe doesnt work, as it only opens regular browser print dialog and gives me ugly page and url information: frames['name'].focus(); frames['name'].print(); Thank you for your time. Kind regards, Marius

• Could not load ruby textmate?

  - by mchenja

  I have a MacBook Pro, running Mavericks, but I'm not too acquainted with its inner workings. I'm just a humble CS student. After install Ruby 1.9.3 and Rails 4.0.0, I get this annoying message every time I open a new terminal window: Unknown ruby interpreter version (do not know how to handle): textmate. Could not load ruby textmate. The message is in bright red, so it worries me. What can I do to fix it/get rid of it? Thanks! EDIT: As it turns out, the message stopped showing, but I can't recall what I did to make it stop. In any case - thanks for reading!

• [change] Vlookup onto another workbook

  - by Arcadian

  Hello, here is my dilemma. I have two worksheets one that has the name of clients and one that i want to copy the names to depending on the city. For instance: associated to each column is last name, first name and city. i have hundreds of names associated to different cities and what i would like is from worksheet1.xls to copy all the New York clients to worksheet2.xls either when i open worksheet2 or via macro what ever is easier and because last name is in one cell and the first name is in the other i would have to copy both. I saw that its possible to link cells from one worksheet to another and then do a vlookup depending on the criteria. Is that the best easiest way or is there another? thanks in advance and cheers oleg

• Maven multi-module project with many reports: looking for an example

  - by hstoerr

  Is there an open source project that can serve as a good example on how to use the maven site plugin to generate reports? I would prefer it to consist of many modules, possibly hierarchically structured use as many plugins as possible (surefire, jxr, pmd, findbugs, javadoc, checkstyle, you name it) the reports should be aggregated: if some tests fail you want to have a single page that shows all modules with failing tests, not only a gazillion individual pages to check include enterprisey stuff (WAR, EAR etc), but this is not so important. The idea is to have something where you can gather ideas on how it is done and what is possible.

• Best approach for building a multiplattform graphical interface for a command-line application

  - by Werner

  Hi, I developed a command line application, whose binary runs in Linux, Windows and Mac OSX. It reads some text input files, but I realize that some special users can not handle this. I would then like to build some kind of graphical interface, where the user only finds buttons and scroll bars for selecting the input parameters, a big "run" button, and then it reads the output of the program and makes some figures. I also need that everything gets finally packed in a single file, which uses only static libraries, so the user just needs to copy the file to his/her machine and run it. I would like to know what is the best open source and multi-platform approach to do this. 10 years ago I played a bit with something similar on DEC machines, so I guess that nowadays the situation has probably improved a bit. P.S. For designing the graphical interface, I am looking for a graphical approach, where you add buttons, scroll bars with the mouse P.S. 2: the interface is really simple, just need less than 10 buttons, 5 text fields and 2 scrolla bars Thanks

  Here is what I do: 1) Create New UIViewController subclass , tick with NIB for interface builder 2) In the header: @interface QuizMainViewController : UIViewController { UILabel* aLabel; } @property (nonatomic, retain) IBOutlet UILabel* aLabel; @end 3) In the .m #import "QuizMainViewController.h" @implementation QuizMainViewController @synthesize aLabel; - (void)dealloc { [aLabel release]; [super dealloc]; } @end 4) Open the NIB In interface builder, drag a new UILabel into the view. I test the program here and it runs fine. 5) right click on file's owner, connect 'aLabel' from the Outlets to the UILabel. I run here and it crashes. Message from log: * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key aLabel.'

• Excel found unreadable content in ...

  - by Rashmi Pandit

  Hi, When I open an excel file (generated through VBA code), I get an error "Excel found unreadable content in <filename>. Do you want to recover the contents?" Upon clicking yes, I get a message 'Repairs were made to PivotTable report 'pvtName' on '[filename.xls]Tab'.' The pivot table in question is generated by the VBA code. Is there a way to figure out what repairs are being done on the pivot table, so that I can make the necessary changes in the code before the file is generated? Thanks :)

• Broadcast-style Bluetooth using Sockets on the iPhone?

  - by Kyle

  Is there any way to open a broadcast bluetooth socket, take a listen and send replies? I want a proper peer to peer system where I broadcast and listen for broadcasts in an area. That way, variable clients can mingle. Is this possible? My theory is this: If GameKit can sit around wasting 25 seconds of the users time whilst having access to a broadcast socket, can't I? Or, must I be in kernel mode for such access? I'm not really sure where the proper bluetooth headers are as well. Thanks for reading!

• How to remotely control a Windows Service with ServiceController?

  - by Amokrane

  Hi, I'm trying to control Windows Services that are installed in a remote computer. I'm using the ServiceController class. I have this: ServiceController svc = new ServiceController("MyWindowsService", "COMPUTER_NAME"); With this, I can get the status of the Windows Service like this: string status = svc.Status.ToString(); But I can't control the Windows Service (by doing svc.Start(); or svc.Stop();). I get the following exception: Cannot open Servicexxx service on computer 'COMPUTER_NAME' That's normal, I suppose there is something to do with access permissions. But how? I've looked into Google but didn't find what I was looking for. However I often read something related to impersonation, but I don't know what that means. NB: The local and remote computers are both running Win XP Pro. Thanks.

• Best way to learn how to use FPGAs

  - by Myrrdyn

  In next weeks probably I will have some little FPGA to play with. I have a programmer background (C, C++, Java mostly) and some (very) limited experience in electronics. What are the best tools to know if you want to develop on FPGAs? What are the best languages to study? (what HW description languages?) Have you some examples of little "toy projects" that can be interesting, easy, and "eye-opener"? Thanks in advance. Edit: More details: if I understood correctly, the device I will be playing on will have an ARM core (no idea which one) and a 300k gates FPGA I'm looking specifically at some Linux free sw / open source tools...
