• How can one connect to an RFCOMM device other than another phone in Android?

  - by Charles Duffy

  The Android API provides examples of using listenUsingRfcommWithServiceRecord() to set up a socket and createRfcommSocketToServiceRecord() to connect to that socket. I'm trying to connect to an embedded device with a BlueSMiRF Gold chip. My working Python code (using the PyBluez library), which I'd like to port to Android, is as follows: sock = bluetooth.BluetoothSocket(proto=bluetooth.RFCOMM) sock.connect((device_addr, 1)) return sock.makefile() ...so the service to connect to is simply defined as channel 1, without any SDP lookup. As the only documented mechanism I see in the Android API does SDP lookup of a UUID, I'm slightly at a loss.

• Using Windows media foundation

  - by Martin Beckett

  Ok so my new gig is high performance video (think Google streetview but movies) - the hard work is all embedded capture and image processing but: I was looking at the new MS video offerings to display content = Windows Media Foundation. Is anyone actually using this ? There are no books on the topic. The only documentation is a developer team blog with a single entry 9 months old. I thought we had got past having to learn an MS api by spying on the com control messages! Is it just another wrapper around the same old activeX control?

• Should I inherit from a stackpanel instead of a stack panel, grid or other UI element or UserControl

  - by Joel Barsotti

  So I'm building a peice of UI that might me in a dialog window or might be in embedded in part of a bigger page. I don't have alot of experience with WPF, but in ASP.NET you always used UserControls, because their wasn't anyt really generic UI inherit to inherit from (and in a way UserControl was just a div). My coworker has written alot of controls that inherit directly from stackpanel. That seems like a decent way of doing things. But when I went to create a control for the code I was going to write I was presented with a dialog that only included the UserControl, which I wasn't that familiar with in the context of WPF. So can someone explain to me the difference from building a control that inherits from user control vs inheriting directly from a stackPanel?

• Oracle account locked

  - by Priya

  Hi All, I had a user in my oracle DB with some 'x' password for sometime. Without notifying my team I changed the password to 'y'. But my team members tried to connect to the machine with the old passowrd 'x' and as the limit was set, the user account got locked. I know how to set the resource limit for the login. It would be helpful if anyone can help in finding who and all has tried to connect to the DB. As a administrator I would like to view from where the connection was from. Thanks in advance. Priya.R

• What are the causes and solutions of exception code c0000005 in mscorwks.dll?

  - by Erick

  The exception code c0000005 is thrown from mscorwks.dll when the application is run on Windows Server 2008 R2. Other platforms (WinXP, Server 2003 R2, Windows 7 32-bit and 64-bit) do not present this exception. The event log from a single execution has many of the following event with event ID 1023 raised by the .NET Runtime: .NET Runtime version 2.0.50727.4952 - Fatal Execution Engine Error (7383851A) (80131506) The application itself makes use of a SOAP interface generated by visual studio from a wsdl, a COM object with an embedded interop, and is targeting .Net 4. sfc /scannow was run and found no problems with system files on the affected system. What trouble shooting can be done to identify a solution?

• Selenium/NUnit run one test on multiple IP addresses.

  - by Matt Clarkson

  I have a test suite DLL written in C# that uses Selenium.This is then loaded into NUnit and tests can be performed on our embedded web server boards. Does anyone know how to run a NUnit Selenium test on multiple IPs in multiple browsers? I have tried creating multiple DefaultSelenium classes but they point to the same Internet Explorer window. I need multiple instances of the Selenium RC controlling individual Internet Explorer windows. Have been looking a lot on the Selenium User Group and in various documentation but can find a definitive answer. Cheers, Matt

• Has anyone run VxWorks on a desktop PC as a target

  - by Steve Roe

  Can I use a desktop PC to run VxWorks as the operating system? In other words, can a standard PC be used as a target processor? I'm not talking about hosting Workbench and a VxSim on the same machine. Rather, I'm considering running just VxWorks (and my application) on a PC. It seems feasible as long as we can configure a board support package, and write or obtain device drivers for the I/O cards on the PCI bus. What I wonder is, has anyone actually done this? I'm interested in saving a bit of money on hardware over a single board computer and cPCI backplane by using a spare desktop sitting around unused. The application is for a test set to be used in a lab. So, I don't need the portability, etc. of a typical embedded processor.

• How do you draw a line from one corner of the stage to the other?

  - by George Edison

  I am completely perplexed. I asked this question and it (any mentioned solution) doesn't seem to be working at all. All I want is to draw a line from one corner to the other. Here again is the link to the SWF file I have (it's embedded in an HTML document): test.html Here is the source: package { import flash.display.Sprite; import flash.events.Event; public class Main extends Sprite { public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point graphics.clear(); graphics.lineStyle(10, 0x000000); graphics.moveTo(0, 0); graphics.lineTo(stage.stageWidth, stage.stageHeight); } } } It just doesn't work! The line goes from somewhere offscreen to about the middle of the stage. What on earth am I doing wrong?

• UIWebViewNavigationTypeLinkClicked event not getting fired for certain links

  - by userlite

  Hi, I am using a UIWebView as an embedded browser within my iphone app. I am using the shouldStartLoadWithRequest function to handle UIWebViewNavigationTypeLinkClicked events for links clicked by a user. It is working as expected for a number of sites, but not for all. For example: when I click on any of the links on website http://www.foxnews.mobi, the UIWebViewNavigationTypeLinkClicked event is not getting fired. Same thing happens for some other sites. I read somewhere that links with blank target do not fire the event, however this is not the cause of the problem in my case. Any help is appreciated. Thanks.

• How to find problem with PHP XSLTProcessor when return from transformToXML is false and libxml_get_

  - by John

  I'm working on the code below to allow HTTP user agents that cannot perform XSL transformations to view the resources on my server. I'm mystified because the result of transformToXML is false, but the result of libxml_get_errors() is an empty array. As you can see, the code outputs the LibXSLT version ID and I'm getting the problem on WinVista with version 1.1.24. Is libxml_get_errors() not the right function to get the errors from the XSLTProcessor object? If you're interested in the XML documents, you can get them from http://bobberinteractive.com/index.xhtml and .../stylesheets/layout.xsl <?php //redirect browsers that can handle the source files. if (strpos ( $_SERVER ['HTTP_ACCEPT'], 'application/xhtml+xml' )) { header ( "HTTP/1.1 301 Moved Permanently" ); header ( "Location: http://" . $_SERVER ['SERVER_NAME'] . "/index.xhtml" ); header ( "Content-Type: text/text" ); echo "\nYour browser is capable of processing the <a href='/index.xhtml' site contents on its own."; die (); } //start by checking the template $baseDir = dirname ( __FILE__ ); $xslDoc = new DOMDocument (); if (! $xslDoc-load ( $baseDir . '/stylesheets/layout.xsl' )) { header ( "HTTP/1.1 500 Server Error" ); header ( "Content-Type: text/plain" ); echo "\n Can't load " . $baseDir . '/stylesheets/layout.xsl'; die (); } //resolve the requested resource (browsers that need transformation will request the resource without the suffix) $uri = $_SERVER ['REQUEST_URI']; $len = strlen ( $uri ); if (1 = $len || '/' == substr ( $uri, $len - 1 )) { $fileName = $baseDir . "/index.xhtml"; // use 'default' document if pathname ends in '/' } else { $fileName = $baseDir . (1 load ( $fileName )) { header ( "HTTP/1.1 500 Server Error" ); echo "\n Can't load " . $fileName; die (); } // now start the XSL template processing $proc = new XSLTProcessor (); $proc-importStylesheet ( $xslDoc ); $doc = $proc-transformToXML ( $xmlDoc ); if (false === $doc) { header ( "HTTP/1.1 500 Server Error" ); header ( "Content-Type: text/plain" ); echo "\n"; // HERE is where it gets strange: the value of $doc is false and libxml_get_errors returns 0 entries. display_xml_errors ( libxml_get_errors() ); die (); } header ( "Content-Type: text/html" ); echo "\n"; echo $doc; function display_xml_errors($errors) { echo count ( $errors ) . " Error(s) from LibXSLT " . LIBXSLT_DOTTED_VERSION; for($i = 0; $i level) { case LIBXML_ERR_WARNING : $return .= "Warning $error-code: "; break; case LIBXML_ERR_ERROR : $return .= "Error $error-code: "; break; case LIBXML_ERR_FATAL : $return .= "Fatal Error $error-code: "; break; } $return .= trim ( $error-message ) .

• WPF Skin Skinning Security Concerns

  - by Erik Philips

  I'm really new to the WPF in the .Net Framework (get that out of the way). I'm writing an application where the interface is very customizable by simply loading .xaml (at the moment a Page element) files into a frame and then mapping the controls via names as needed. The idea is to have a community of people who are interested in making skins, skin my application however they want (much like Winamp). Now the question arises, due to my lack of Xaml knowledge, is it possible to create malicious Xaml pages that when downloaded and used could have other embedded Iframes or other elements that could have embed html or call remote webpages with malicious content? I believe this could be the case. If this is the case then I two options; either I have an automated process that can remove these types of Xaml files by checking it’s elements prior to allowing download (which I would assume would be most difficult) or have a human review them prior to download. Are there alternatives I’m unaware of that could make this whole process a lot easier?

• SSMS Results to Grid - CRLF not preserved in copy/paste - any better techniques?

  - by Cade Roux

  When I have a result set in the grid like: SELECT 'line 1 line 2 line 3' or SELECT 'line 1' + CHAR(13) + CHAR(10) + 'line 2' + CHAR(13) + CHAR(10) + 'line 3' With embedded CRLF, the display in the grid appears to replace them with spaces (I guess so that they will display all the data). The problem is that if I am code-generating a script, I cannot simply cut and paste this. I have to convert the code to open a cursor and print the relevant columns so that I can copy and paste them from the text results. Is there any simpler workaround to preserve the CRLF in a copy/paste operation from the results grid? The reason that the grid is helpful is that I am currently generating a number of scripts for the same object in different columns - a bcp out in one column, an xml format file in another, a table create script in another, etc...

• Ghosting context menu clicks in WinXP

  - by Swish

  Let me preface by saying I have a lot of windows open most of the time, although not resource intensive ones, just browsers, ssh sessions, a music player, FTP client, Notepad++, IM clkients, etc. Anyway, I get a lot of weird visual "ghosting" type effects. For example when right-clicking and then selecting an option from a context menu the selected item will remain in view until I right click somewhere on the desktop. Same thing happens when selecting items from the File, Edit, etc. menu in various programs. I'm assuming this is just a result of a less than high quality video card (NVIDIA GeForce FX 5200), all the other hardware in the machine is newer higher quality, that specific video card was added after the fact for multiple monitors. I have looked all over the web for solutions and have increased the number of GDI handles for Windows, reduced the hardware accelaration on the card, etc. Any suggestions other than replace the card?

• AS3 mouseX and mouseY values wrong in Firefox

  - by Gerard

  Hi there, I'm getting some strange behaviour in my Flash movie, only in Firefox for MAC (3.6.2). Basically, the mouseX and mouseY properties of all display objects become massive numbers: < 100000000. This issue only occurs on Firefox, it is not present when the movie is run standalone, nor when it is run on any other browser. The swf requires Flash Player 10, and is written in AS3. It is also embedded via SWFObject, but I tested using the export code supplied with Flash and verified the issue is still present. Has anybody heard of this? Is it a Flash or Firefox bug? Is it a bug at all? Thanks

• My internet connection just got really slow - How can I troubleshoot it?

  - by Walden

  A few days ago my connection became really slow. I have DSL which should be 3mb down and 768k up. I'm lucky if I get 768k down and 200k up. It sucks. I called my ISP, Verizon and they did some sort of line test and told me the problem was on my end. I rebooted my modem several times, like they told me. I'm not really sure why I even bothered calling them, the guy on the other end was just reading stuff out of a notebook - pretty useless. So, I checked my network traffic in windows resource monitor, and there doesn't seem to be anything there hogging the bandwidth. What else could be slowing my connection down on my PC? on my router? Something else?

• Setting WPF image source in code

  - by Torbjørn

  I'm trying to set a WPF image's source in code. The image is embedded as a resource in the project. By looking at examples I've come up with the below code. For some reason it doesn't work - the image does not show up. By debugging I can see that the stream contains the image data. So what's wrong? Assembly asm = Assembly.GetExecutingAssembly(); Stream iconStream = asm.GetManifestResourceStream("SomeImage.png"); PngBitmapDecoder iconDecoder = new PngBitmapDecoder(iconStream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default); ImageSource iconSource = iconDecoder.Frames[0]; _icon.Source = iconSource; The icon is defined something like this: <Image x:Name="_icon" Width="16" Height="16" />

• Is it possible to resize a SpriteAsset without adding it to the display list?

  - by Sophistifunk

  Hi guys, I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list. I try this: spriteAsset.setActualSize(w,h); spriteAsset.width = w; bmd.draw(spriteAsset); But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image. Any pointers? Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills? Cheers, -Josh

• Windows 7 Computer Maintenance - Restore removed Desktop Shortcuts

  - by HaydnWVN

  I'm aware about the inbuilt nightmate 'tool' of Microsofts which is making every network administrators job a nightmare (if left turned on). In short it'll happily delete every desktop shortcut to a network resource. We have it disabled by default. My question is related to recovering these shortcuts, Windows doesn't seem to dump them into the Recycle Bin and although you can 'restore previous versions' of the Desktop folder, you are unable to do it with the user logged in... Rather a problem if you only have the 1 user account. We have a user who (although the 'Computer Maintenance' tool is turned off) had it come up in 'Action Centre' and chose to run it. I've been unable to reproduce it, but the tool has certainly run (and removed 24 shortcuts from her desktop) although it is still saying 'Windows is not checking your system for maintenance problems'. ?! Very fustrating! Any ideas if these shortcuts are backed up/moved elsewhere so i can easily find and restore them?

• C#, WPF. Length of string that will fit in a specific width.

  - by Ian

  Hi, I'm sure I'm missing something obvious, I have an area in which I intend to draw text. I know its (the area) height and width. I wish to know how many characters/Words will fit in the width, characters preferably. Second question, If the line is too long I'll want to draw a second line, so I guess I need to get the height of the text as well, including what ever it considers the right vertical padding? I'd also rather like to know the inverse, i.e. how many characters I can fit in a specific width. I assume the fact that WPF isn't constrained to pixels will have some bearing on the answer? Ultimately I'm planning on wrapping text around irregular shaped images embedded in the text. Any pointers in the right direction would be great. Thanks

• Flash AS3 and XML: way to fix line breaks in htmlText that uses <b> tags in the xml?

  - by HeroicNate

  I'm importing text in from an xml file and i'm using htmlText to try to keep some styling with tags. I have both the regular and bold face font embedded, and the bolding works fine. The problem is that it ads spaces around the words in bold like a paragraph indent and then makes a line-break after them. What's going on, is there a way to fix? fromxmlText.htmlText = theXML.contenttext; If I pull the text in from a txt file it will work fine, but taking it out of an xml file causing funky formatting. lil' help?

• Import and Export for CSV are both broken in Mathematica

  - by dreeves

  Consider the following 2 by 2 array: x = {{"a b c", "1,2,3"}, {"i \"comma-heart\" you", "i \",heart\" u, too"}} If we Export that to CSV and then Import it again we don't get the same thing back: Import[Export["tmp.csv", d]] Looking at tmp.csv it's clear that the Export didn't work, since the quotes are not escaped properly. According to the RFC which I presume is summarized correctly on Wikipedia's entry on CSV, the right way to export the above array is as follows: a b c, "1,2,3" "i ""heart"" you", "i "",heart"" u, too" Importing the above does not yield the original array either. So Import is broken as well. I've reported these bugs to [email protected] but I'm wondering if others have workarounds in the meantime. One workaround is to just use TSV instead of CSV. I tested the above with TSV and it seems to work (even with tabs embedded in the entries of the array).

• how to configure my internal dns to resolve external resources

  - by Ralph Shillington

  I have an internal DNS as part of my AD setup. I have an hosted DNS for public resources (which are typically at some data centre somewhere) Occasionally while on our internal network I need to get to a public resource --- for example www.ourcompany.com since there isn't a www record in our internal DNS I cant get the name resolved. How do I configure my DNS to forward names it doesn't recognise to the public DNS. Update: As per the comment yes I have a "split-horizon" dns (which seemed like a good idea at the time) This AD setup is less than 24 hours old, and can be redone if need be -- (although I would rather not)
