  • Manage 2 displays remotely

    - by neurino
    I have a pc with a nVidia Quadro graphic card. The card has 2 DisplayPort outs where 2 40" Full HD TV are connected. I need to run 2 separate fullscreen videos, one each display. The problem is displays are far from the pc station and I cannot control them from there. I tried with a remote desktop connection but when I connect screen 1 shows login and screen 2 simply blackens (I'm logged off). The pc, an HP, also has his native graphics card still installed it would be nice if I could connect there a 15" monitor with the desktop on and use the TVs only as secondary where I can send fullscreen videos. Any clue?

  • How can I automatically switch audio to my speakers when my TV-as-2nd-monitor is not in use?

    - by Michael McGowan
    I have a normal LCD monitor as my primary monitor and an HD LCD television as a 2nd monitor (connected through HDMI). I also have a set of normal speakers for the computer (a Windows 7 machine) that I previously used (before I was using the TV as a 2nd monitor). When I am using the TV as a 2nd monitor, I would like audio to come from it. However, I'm oftentimes using the TV as a TV, in which case I would like the audio from my computer to come from my speakers. Is there any way to accomplish this? It seems that if I have the TV set up as the default audio, then even if I turn the TV off (or, more likely, to the input from my cable box), then the audio still goes through that rather than my speakers. Is there a solution that does not require me to manually change the settings every time I want to switch contexts?

  • Ubuntu 9.10 Karmic, nVidea Quadro NVS 280 PCi, Eizo S1921 Dual Screen (Twin View) Slow Window Draws

    - by Spasm
    I have been following this Tutorial to get dual monitors working on my box http://www.dwasifar.com/?p=862&cpage=1#comment-5727 It works! However, when ever I move a window, the redraw of that window takes 3-8 seconds. Even moving the window takes the same amount of time Is this being done in software rather than the nVidea hardware? The windows themselves do not respond. I have seen a few old threads but no relevant fixes - If anyone could suggest a fix I would very much appreciate it. I have tried: sudo nvidea-xconfig sudo nvidia-settings Then configure TwinView go to save the config... and the error unable to parse xorg.conf file and the error in the console VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf. Undefined Device "null" referenced by Screen "Configured Screen Device" Segmentation fault

  • Display on secondary video card (Nvidia 8400 GS): horrible refresh, bogs system

    - by minameismud
    This is my work computer, but it's a small shop. We do business software development. The most hardcore thing we create is some web animations with html5 and fancy javascript/css. The base machine is a Dell Precision T3500 - Xeon W3550 (3.07GHz quad), 6GB ram, pair of 500GB harddrives, and Win 7 x64 Enterprise SP1. My primary video card is an ATI FirePro V4800 1GB in a PCIe slot of some speed driving a pair of 23s at 1920x1080 through DisplayPort-HDMI adapters. The secondary card is an NVidia GeForce 8400GS in a PCI slot driving a single 17" at 1280x1024 through DVI. On either of the 23" monitors, windows move smoothly, scroll quickly, and are generally very responsive. On the 17", it's slow, chunky, and when I'm trying to scroll a ton of content, Windows will occasionally suggest I drop to the Windows Basic theme. I've updated drivers for both cards, and I've gotten every Windows update relating to video. Specifically: ATI FirePro Provider: Advanced Micro Devices, Inc Date: 6/22/2014 Version: 13.352.1014.0 NVidia 8400 GS Provider: NVIDIA Date: 7/2/2014 Version: 9.18.13.4052 Unfortunately, new hardware isn't really an option. Is there anything I can do software-wise to speed up the NVidia-driven monitor?

  • 3 Monitors to a single pc

    - by Rogue
    First of all which graphics cards support 3 monitors? Is it possible to buy a graphics card which has 2 outputs and use the onboard (motherboard) graphics output for the third monitor? (as far as I know you have to toggle between onboard or external graphics usage in the BIOS)

  • Can no longer duplicate display to external monitor on Windows 7

    - by rbeier
    We have a large TV at work - I connect my laptop to it to share my screen during meetings. Until today, my laptop display has been duplicating to the TV automatically when I connect the TV cable to the laptop. The display resolution would decrease automatically to be compatible with the TV. Today, however, it's stopped working. When I connect the cable to the TV, the display extends rather than duplicating. Using the Win+P key combination (or Fn+F7 on my Lenovo laptop), I can choose to duplicate the display - but when I do this, it ends up only displaying on the laptop. I can get it to display on the TV by hitting Win+P and choosing "projector only", but then I can't see what I'm doing on the laptop screen. I have a Lenovo W520 laptop running Windows 7, connected to the TV using a DisplayPort-to-HDMI converter cable. The TV's native resolution is 1280x720; the laptop's native resolution is 1600x900. I've tried booting with the TV cable already connected; I've tried manually lowering the display resolution on the laptop to 1280x720 before duplicating the display. Neither works. Does anyone have any other suggestions?

  • What is the process for diagnosing a ViewSonic Monitor? [closed]

    - by Phxvyper
    I have a ViewSonic monitor that has been busted for quite some time. I've been researching it and i still have no clue as to why it doesn't work. It doesn't turn on. Or rather, it will turn on, but it will not display anything. How do i go about diagnosing the monitor? The monitor is a: ViewSonic VG2230WM Model #: VS11422 Fix: I opened up the monitor and replaced all of the burst capacitors. The monitor works beautifully now.

  • Duplicate monitor on highest resolution in Windows 7

    - by AlexanderMP
    I have a monitor with a native resolution of 2560x1440, connected through display port. I also have an AV Receiver connected to the video card via HDMI, to have surround sound in games. All using Radeon HD 5670 (will upgrade soon to HD 7850). The problem is that my computer detects the receiver as a separate monitor, with the highest available resolution of 1920x1080. I have 3 options: Disconnect the second display. But then the sound (digital audio output through video card) also disappears. Duplicate displays. But then my primary monitor resolution is reduced to a maximum of just 1920x1080, that being the maximum of the second monitor. Extend desktop. This is the solution I picked so far, it being the least evil. The problems I face in this situations are 2: I have a blank part of the desktop where I sometimes lose my mouse pointer, so I made the extension small, 640x480, and placed it in a corner; when I turn off the main display, all windows resize to 640x480. In Kubuntu I had the option to duplicate the displays, while keeping the higher resolution. Which was great. I tried overriding using the Win7 netbook hack, but it's not available on non-netbooks. Is there a similar solution for this problem in Windows 7?

  • Easily Plotting Multiple Data Series in Excel

    - by John
    I really need help figuring out how to speed up graphing multiple series on a graph. I have seperate devices that give monthly readings for several variables like pressure, temperature, and salinity. Each of these variables is going to be its own graph with devices being the series. My x-axis is going to be the dates that these values were taken. The problem is that it takes ages to do this for each spreadsheet since I have monthly dates from 1950 up to the present and I have about 50 devices in each spreadsheet. I also have graphs for calculated values that are in columns next to them. Each of these devices is going to become a data series in the graph. E.g. In one of my graphs I have all the pressures from the devices and each of the data series' names is the name of the device. I want a fast way to do this. Doing this manually is taking a very long time. Please help! Is there any easier way to do this? It is consistent and the dates all line up. I am just repeating the same clicks over and over again Thank you!

  • How to toggle between different monitors with one key on Windows 7?

    - by user443854
    I recently found a post on switching between different sound cards with one key stroke (the answer I ended up using is Default Audio Changer). I am looking for similar functionality for switching between monitors. Win+P is not good enough, as it loops between four choices: Computer | Duplicate | Extend | Projector, and I want to toggle only between two monitors. It also takes at least four key strokes to toggle.

  • Multiple if functions

    - by user2948699
    I have problem I'm hoping someone could help me with. I have five different text values in 5 cells. I am trying to combine these values into one cell with a comma in between each. However the trick is that if there is no value in (H6) then it must place the word "and" between the cell (F6) and (G6). If there is a value in (H6) then place the word "and" between (G6) and (H6). In the same statement I must also include If there is not value in (G6) then it must place the word "and" between the cell E6 and F6. Please see image attached. I am trying to get the highlighted statements into one cell. So multiple IF statements into one cell. Anyone? =IF(G8=0,(D8)&", "&(E8)&" and "&(F8),(D8)&", "&(E8)&", "&(F8)&" and "&(G8)=IF(H8=0,(D8)&", "&(E8)&", "&(F8)&" and "&(G8),(D8)&", "&(E8)&", "&(F8)&", "&(G8)&" and "&(H8))) I cant figure out the code. Many thanks. Alex Edit: The original image can be found here if size of the inlined is too small.

  • Django app that can provide user friendly, multiple / mass file upload functionality to other apps

    - by hopla
    Hi, I'm going to be honest: this is a question I asked on the Django-Users mailinglist last week. Since I didn't get any replies there yet, I'm reposting it on Stack Overflow in the hope that it gets more attention here. I want to create an app that makes it easy to do user friendly, multiple / mass file upload in your own apps. With user friendly I mean upload like Gmail, Flickr, ... where the user can select multiple files at once in the browse file dialog. The files are then uploaded sequentially or in parallel and a nice overview of the selected files is shown on the page with a progress bar next to them. A 'Cancel' upload button is also a possible option. All that niceness is usually solved by using a Flash object. Complete solutions are out there for the client side, like: SWFUpload http://swfupload.org/ , FancyUpload http://digitarald.de/project/fancyupload/ , YUI 2 Uploader http://developer.yahoo.com/yui/uploader/ and probably many more. Ofcourse the trick is getting those solutions integrated in your project. Especially in a framework like Django, double so if you want it to be reusable. So, I have a few ideas, but I'm neither an expert on Django nor on Flash based upload solutions. I'll share my ideas here in the hope of getting some feedback from more knowledgeable and experienced people. (Or even just some 'I want this too!' replies :) ) You will notice that I make a few assumptions: this is to keep the (initial) scope of the application under control. These assumptions are of course debatable: All right, my idea's so far: If you want to mass upload multiple files, you are going to have a model to contain each file in. I.e. the model will contain one FileField or one ImageField. Models with multiple (but ofcourse finite) amount of FileFields/ ImageFields are not in need of easy mass uploading imho: if you have a model with 100 FileFields you are doing something wrong :) Examples where you would want my envisioned kind of mass upload: An app that has just one model 'Brochure' with a file field, a title field (dynamically created from the filename) and a date_added field. A photo gallery app with models 'Gallery' and 'Photo'. You pick a Gallery to add pictures to, upload the pictures and new Photo objects are created and foreign keys set to the chosen Gallery. It would be nice to be able to configure or extend the app for your favorite Flash upload solution. We can pick one of the three above as a default, but implement the app so that people can easily add additional implementations (kinda like Django can use multiple databases). Let it be agnostic to any particular client side solution. If we need to pick one to start with, maybe pick the one with the smallest footprint? (smallest download of client side stuff) The Flash based solutions asynchronously (and either sequentially or in parallel) POST the files to a url. I suggest that url to be local to our generic app (so it's the same for every app where you use our app in). That url will go to a view provided by our generic app. The view will do the following: create a new model instance, add the file, OPTIONALLY DO EXTRA STUFF and save the instance. DO EXTRA STUFF is code that the app that uses our app wants to run. It doesn't have to provide any extra code, if the model has just a FileField/ImageField the standard view code will do the job. But most app will want to do extra stuff I think, like filling in the other fields: title, date_added, foreignkeys, manytomany, ... I have not yet thought about a mechanism for DO EXTRA STUFF. Just wrapping the generic app view came to mind, but that is not developer friendly, since you would have to write your own url pattern and your own view. Then you have to tell the Flash solutions to use a new url etc... I think something like signals could be used here? Forms/Admin: I'm still very sketchy on how all this could best be integrated in the Admin or generic Django forms/widgets/... (and this is were my lack of Django experience shows): In the case of the Gallery/Photo app: You could provide a mass Photo upload widget on the Gallery detail form. But what if the Gallery instance is not saved yet? The file upload view won't be able to set the foreignkeys on the Photo instances. I see that the auth app, when you create a user, first asks for username and password and only then provides you with a bigger form to fill in emailadres, pick roles etc. We could do something like that. In the case of an app with just one model: How do you provide a form in the Django admin to do your mass upload? You can't do it with the detail form of your model, that's just for one model instance. There's probably dozens more questions that need to be answered before I can even start on this app. So please tell me what you think! Give me input! What do you like? What not? What would you do different? Is this idea solid? Where is it not? Thank you!

  • Defining multiple values in DefineConstants in MsBuild element?

    - by Sardaukar
    I'm currently integrating my Wix projects in MSBuild. It is necessary for me to pass multiple values to the Wix project. One value will work (ProductVersion in the sample below). <Target Name="BuildWixSetups"> <MSBuild Condition="'%(WixSetups.Identity)'!=''" Projects="%(WixSetups.Identity)" Targets="Rebuild" Properties="Configuration=Release;OutputPath=$(OutDir);DefineConstants=ProductVersion=%(WixSetups.ISVersion)" ContinueOnError="true"/> </Target> However, how do I pass multiple values to the DefineConstants key? I've tried all the 'logical' separators (space, comma, semi-colon, pipe-symbol), but this doesn't work. Has someone else come across this problem? Solutions that don't work: Trying to add a DefineConstants element does not work because DefineConstants needs to be expressed within the Properties attribute.

  • getting an embedded resource in a single dll made up of multiple class libraries

    - by Rahul Gupta
    my solution has multiple projects and in one of them I have the code to get the embedded resource (an xml file) from another project. All this works fine when all the projects are seperate. However when all the class libraries are embedded into a single dll, the code to get the resource file does not work i.e. it cannot get the emebedded resource. I was wondering if the references to the emebedded resource get mixed up when they are combined together in a single dll?? I use the method Assembly.GetCallingAssembly().GetManifestResourceStream("namespace..filename");

  • Deploy multiple instances of an EAR (representing versions) to Glassfish

    - by Thorbjørn Ravn Andersen
    I basically want to be able to deploy multiple versions of the same EAR file to the same server (Glassfish instance?) , and have a unique path to each version separating them. From my reading on this it appears that multiple EARs deploy to the root of the web server namespace so that they can coexist if they do not have colliding context-root's of WAR's. In my case I'd rather have that instead of everything going under "/", I'd like to be able to brand a given EAR-file build to ALWAYS deploy under a given path like "/foo-20100319" or "/foo-CUSTOMER-20010101". This can easily be done with a single WAR file just by renaming it. I do not need or want them to disturb each other. It is my understanding that this remapping is outside the scope of the application.xml file, so I found that http://docs.sun.com/app/docs/doc/820-7693/beayr?a=view says that I can specify web-uri and context-root, but I am not certain that what I wish to do, can be specified with these in Glassfish. How should I approach this? I have full control over the build process. (I have found http://stackoverflow.com/questions/877390/deploying-multiple-java-web-apps-to-glassfish-in-one-go but I am not certain how to apply this to what I need).

  • DB2Command ExecuteNonQuery Insert multiple rows problem

    - by DB2 Nubie
    I'm attempting to insert multiple rows into a DB2 database using C# code like this: string query = "INSERT INTO TESTDB2.RG_Table (V,E,L,N,Q,B,S,P) values" + "('lkjlkj', 'iouoiu', '2009-03-27 12:01:19', 'nnne', 'sdfdf', NULL, NULL, NULL)," + "('lkjlk2', 'iuoiu2', '2009-03-27 12:01:19', 'nnne2', 'sddf2', NULL, NULL, NULL)"; DB2Command cmd = new DB2Command(query, this.transactionConnection, this.transaction); cmd.ExecuteNonQuery(); If I stop building the query string after the first set of values is included it executes without an error. Attempting to load multiple values using this method results in the following error: Upload error : ERROR [42601] [IBM][DB2] SQL0104N An unexpected token "," was found following "". Expected tokens may include: "". SQLSTATE =42601 The SQL syntax matches that which I have read elsewhere, such as http://stackoverflow.com/questions/452859/inserting-multiple-rows-in-a-single-sql-query and IBM's documentation gives this example: cmd = conn.CreateCommand(); cmd.Transaction = trans; cmd.CommandText = "INSERT INTO company_a VALUES(5275, 'Sanders', 20, 'Mgr', 15, 18357.50), " + "(5265, 'Pernal', 20, 'Sales', NULL, 18171.25), " + "(5791, 'O''Brien', 38, 'Sales', 9, 18006.00)"; cmd.ExecuteNonQuery(); Can anyone explain what could account for this?

  • Call Multiple Stored Procedures with the Zend Framework

    - by Brian Fisher
    I'm using Zend Framework 1.7.2, MySQL and the MySQLi PDO adapter. I would like to call multiple stored procedures during a given action. I've found that on Windows there is a problem calling multiple stored procedures. If you try it you get the following error message: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. I found that to work around this issue I could just close the connection to the database after each call to a stored procedure: if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') { //If on windows close the connection $db->closeConnection(); } This has worked well for me, however, now I want to call multiple stored procedures wrapped in a transaction. Of course, closing the connection isn't an option in this situation, since it causes a rollback of the open transaction. Any ideas, how to fix this problem and/or work around the issue.

  • Install multiple iPhone apps at once from Xcode to device

    - by Dimitris
    Supposing we have an Xcode iPhone project with 2 targets, is it possible to build and install both of them on the device with one click? Of course, I understand we will not be able to "build and run" both, but can we at least install them? And to extend this concept a bit a bit: are there any scripts to achieve the same thing but with multiple iPhone projects instead of multiple targets in one project? This would be useful when you want to load all your apps on a new development device and don't want to go through all your projects one by one and install.

  • Maven best practice for generating multiple jars with different/filtered classes ?

    - by jaguard
    I developed a Java utility library (similarly to Apache Commons) that I use in various projects. Additionally to fat clients I also use it for mobile clients (PDA with J9 Foundation profile). In time the library that started as a single project spread over multiple packages. As a result I end up with a lot of functionality but not really needed in all the projects. Since this library is also used inside some mobile/PDA projects I need a way to collect just the used classes and generate the actual specialized jars Currently in the projects that area using this library, I have Ant jar tasks that generate (from the utility project) the specialized jar files (ex: my-util-1.0-pda.jar, my-util-1.0-rcp.jar) using include/exclude jar task features. This is mostly needed due to the generated jar size constraints for the mobile projects. Migrating now to Maven I just wonder if there are any best practices to arrive to something similar so I consider the following scenarios: [1] - additionally to the main jar artifact (my-lib-1.0.jar) also generating inside my-lib project the separate/specialized artifacts using classifiers (ex: my-lib-1.0-pda.jar) using Maven Jar Plugin or Maven Assembly Plugin filtering/includes ... I'm not very comfortable with this approach since it pollute the library with library consumers demands (filters) [2] - Create additional Maven projects for all the specialized clients/projects, that will "wrap" the "my-lib" and generate the filtered jar artifacts (ex: my-lib-wrapper-pda-1.0 ...etc). As a result, these wrapper projects will include the filtering (to generate the filtered artifact) and will depend just on the "my-lib" project and the client projects will depend on my-lib-wrapper-xxx-1.0 instead of my-lib-1.0. This approach my look problematic since even that will let "my-lib" project intact (with no additional classifiers & artifacts), basically will double the number of projects since for every client project I'll have one just to collect the needed classes from the "my-util" library ("my-pda-app" project will need a "my-lib-wrapper-for-my-pda-app" project/dependency) [3] - Into the every client project that use the library (ex: my-pda-app) add some specialized Maven plugins to trim - out (when generating the final artifact/package) the un-needed classes (ex: maven-assembly-plugin, maven-jar-plugin, proguard-maven-plugin) What is the best practice for solving this kind of problems in the "Maven way" ?!

  • Is there any way to optimize this LINQ where clause that searches for multiple keywords on multiple

    - by Daniel T.
    I have a LINQ query that searches for multiple keywords on multiple columns. The intention is that the user can search for multiple keywords and it will search for the keywords on every property in my Media entity. Here is a simplified example: var result = repository.GetAll<Media>().Where(x => x.Title.Contains("Apples") || x.Description.Contains("Apples") || x.Tags.Contains("Apples") || x.Title.Contains("Oranges") || x.Description.Contains("Oranges") || x.Tags.Contains("Oranges") || x.Title.Contains("Pears") || x.Description.Contains("Pears") || x.Tags.Contains("Pears") ); In other words, I want to search for the keywords Apples, Oranges, and Pears on the columns Title, Description, and Tags. The outputted SQL looks like this: SELECT * FROM Media this_ WHERE (((((((( this_.Title like '%Apples%' or this_.Description like '%Apples%') or this_.Tags like '%Apples%') or this_.Title like '%Oranges%') or this_.Description like '%Oranges%') or this_.Tags like '%Oranges%') or this_.Title like '%Pears%') or this_.Description like '%Pears%') or this_.Tags like '%Pears%') Is this the most optimal SQL in this case? If not, how do I rewrite the LINQ query to create the most optimal SQL statement? I'm using SQLite for testing and SQL Server for actual deployment.

  • Multiple Application Support Directories for iPhone Simulator?

    - by Alex G
    I am developing an iPhone app with someone else. The app works fine for me, but he is running into a bug. We think this bug is related to the fact that he is getting multiple Application directories for this same app. In my ~/Library/Application Support/iPhone Simulator/User/Applications, I only have one folder at all times. He says that he will get 3 or 4 directories when he is only working on this one app. We think this is our problem because our bug has to do with displaying images that are stored in the app's Documents folder. Does anyone know why he is ending up with multiple directories or how to stop it? Edit: Here is the code for writing the image to a file: NSData *image = [NSData dataWithContentsOfURL:[NSURL URLWithString:[currentArticle articleImage]]]; NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; NSFileManager *NSFM = [NSFileManager defaultManager]; BOOL isDir = YES; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/images"]; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/%@.jpg", [currentArticle uniqueID]]; [image writeToFile:imagePath atomically:NO]; And here is the code for getting the path when I need the image: - (NSString *)imagePath { NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; return [imagePath stringByAppendingFormat:@"/images/%@.jpg", [self uniqueID]]; } The app works great for me, but my partner says that the images don't show up intermittently, and he notices that he gets multiple directories in his Applications folder.
