• Synergy on Linux and Linux

  - by archer

  Using Synergy-plus-1.3.4 on Gentoo Linux kernel 2.6.36-tuxonice-r3. Using SHIFT+CAPS to change keyboard layout on BOTH server and client boxes. Works perfectly if change layout using attached keyboard. But when using synergy keyboard (moved mouse from server screen to client and changing with SHIFT+CAPS) it has no effect. Synergy is just amazing thing exception this small issue which I'm assured is solvable. Please, gimme some hint.

• Custom ValidationAttribute test against whole model

  - by griegs

  I know this is probably not possible but let's say I have a model with two properties. I write a ValidationAttribute for one of the properties. Can that VA look at the other property and make a decision? So; public class QuickQuote { public String state { get; set; } [MyRequiredValidator(ErrorMessage = "Error msg")] public String familyType { get; set; } So in the above example, can the validator test to see what's in the "state" property and take that into consideration when validating "familyType"? I know I can probably save the object to the session but would like to avoid any saving of state if possible.

• Entity Framework Custom T4 Template

  - by s7orm

  Hello, I am using the Entity Framework 4.0 and I am trying to extend my POCO classes generated by the standart T4 template with some custom properties. The classes which are generated by default from EF (without T4) contain 2 properties for every navigation property - NavigationPropertyId and navigationPropertyReference. What I am trying to do is basically extend the generated POCO class with an "Id" property of the foreign key object. I know that I can do that by editing the POCO t4 template. However I have no idea how I can populate/persist the property - I guess I have to somehow extend/modify the method than converts the object to a sql query and vice versa, but I have no idea where to start. Can anyone help? Edit: I just found out, that the EF team has planned to implement something like this - http://blogs.msdn.com/efdesign/archive/2010/03/10/poco-template-code-generation-options.aspx (see Basic POCO with/without Fixup), however this can take ages, so I rather implement it myself.

• VS2008: Add custom build rule to a Property Sheet (vsprops)?

  - by shoosh

  I'm using the CUDA .rules file which comes with the CUDA SDK for custom build steps in my project. To save on property duplication I'd like to define the properties of the CUDA rule in a .vsprops file. For some reason, the CUDA rule branch of the properties tree does not show under any of my property sheets, only under the main configurations sheets. I tried editing the .vsprops with a text edition and add the section by hand but there is no change it still does't show when in visual studio. Is there a way to do this?

• How do I manage library symbols with linked classes in Flash CS4 to compile/debug in Flash Builder 4

  - by wpjmurray

  I'm building a video player using Flash CS4 (hereby referred to as "Flash") to create the graphic symbols and compiling and debugging with Flash Builder 4 ("FB4"). Here are the steps I take in my current workflow: --Create the graphic symbols in Flash. I've created a few different symbols for the player, but I'll focus on just the play/pause button ("ppbutton") here. --In the Library panel, I go to the ppbutton symbol's Linkage properties and link to a class named assets.PlayPauseButtonAsset that extends MovieClip. I do not actually have an assets package nor do I have a class file for PlayPauseButtonAsset as Flash will create them for me when I publish. --In Flash's Publish settings, I set the project to export a SWC that will be used in FB4, called VideoPlayerAssets.swc. --After the SWC is created, I create my FB4 project called "VideoPlayer" and add the SWC to my path. FB4 creates the class VideoPlayer in the default package automatically. --In VideoPlayer.as, I import assets.*, which imports all of the symbol classes I created in Flash and are available via VideoPlayerAssets.swc. I can now instantiate the ppbutton and add to the stage, like this: var ppbutton:PlayPauseButtonAsset = new PlayPauseButtonAsset(); addChild(ppbutton); At this point ppbutton doesn't have any functionality because I didn't create any code for it. So I create a new class called video.controls.PlayPauseButtonLogic which extends assets.PlayPauseButtonAsset. I add some logic, and now I can use that new class to put a working ppbutton on the stage: var ppbutton:PlayPauseButtonLogic = new PlayPauseButtonLogic(); addChild(ppbutton); This works fine, but you may be asking why I didn't just link the ppbutton symbol in Flash to the video.controls.PlayPauseButtonLogic class in the first place. The reason is that I have a designer creating the UI in Flash and I don't want to have to re-publish the SWC from Flash every time I make a change in the logic. Basically, I want my designer to be able to make a symbol in Flash, link that symbol to a logically named class in Linkage properties, and export the SWC. I do not want to have to touch that .fla file again unless the designer makes changes to the symbols or layout. I'm using a versioning system for the project as well and it's cleaner to make sure only the designer is touching the .fla file. So, finally, here's the issue I'm running into: --As the design gets more complex, the designer is nesting symbols to position the video controls on the control bar. He creates a controlbar symbol and links it to assets.ControlBarAsset. The controlbar symbol contains the ppbutton symbol. --The designer publishes the SWC and ControlBarAsset is now available in FB4. I create new class called video.controls.ControlBarLogic that extends assets.ControlBarAsset so I can add some logic to the controlbar, and I add the controlbar to the stage: var controlbar:ControlBarLogic = new ControlBarLogic(); addChild(controlbar); --This works, but the ppbutton doesn't do anything. That's because ppbutton, while inside controlbar, is still only linked to PlayPauseButtonAsset, which doesn't have any logic. I'm no longer instantiating a ppbutton object because it's part of controlbar. That's where I'm stuck today. I can't seem to simply re-cast controlbar's ppbutton as PlayPauseButtonLogic as I get a Type error. And I don't want to have to make a class that has to instantiate each of the video player controls, the place them at their x and y values on the stage according to how the designer placed them, as that would require me to open the .fla and check the various properties of a symbol, then add those values to the code. If the designer made a change, I'd have to go into the code each time just to update those properties each time. Not good. How do I re-cast nested symbols to use the logic classes that I create that extend the asset classes? Remember, the solution is not to link Flash symbols to actual classes so I don't have to keep recompiling the SWC, unless there's a way to do that without having to re-compile the SWC. I want the designer to do his thing, publish the SWC, and be done with it. Then I can take his SWC, apply my logic to his assets, and be able to debug and compile the final SWF.

  Hi all, The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized.

• Dynamips and Tap Devices, To and From the same machine

  - by Kyle Brandt

  I am setting up a dynamips/dynagen lab and am wondering if there is any way to get traffic to route out one tap devices, go into the lab, and come back to a tap device on the same machine. I have tried host specific routes as well as removing the route created when I give the tun device an ip via ifconfig. With both of these, traffic always preferes the attached devices and won't go through my lab. Any way to make this work without a separate machine or vm?

• Get HDD (and NOT Volume) Serial Number on Vista Ultimate 64 bit

  - by TheAgent

  Hi all. I was once looking for getting the HDD serial number without using WMI, and I found it. The code I found and posted on StackOverFlow.com works very well on 32 bit Windows, both XP and Vista. The trouble only begins when I try to get the serail number on 64 bit OSs (Vista Ultimate 64, specifically). The code returns String.Empty, or a Space all the time. Anyone got an idea how to fix this?

• GUI to include a .prop` file to a VS 2010 project?

  - by jwfearn

  Visual Studio 2010 has no longer uses .vsprops files and instead uses .props files. To include a .vsprops file in a Visual Studio 2008 project, one could right-click the project icon in the Solution Explorer panel, choose Properties, go to the Configuration Properties | General section, and modify the Inherited Project Property Sheets property to contain a list of .vsprops paths. One could also modify the Visual Studio 2008 project file directly. Is there a way in the Visual Studio 2010 GUI to include .props files to a project? The Inherited Project Property Sheets property seems to have been removed. If manual editing of the project file is the only way to include .props files, where can one find documentation on doing it? I'm not talking about adding a .props file to the list of files in the project, I mean how do I tell the project to use a .props file.

• .Net reflection to get description of class / property etc?

  - by ClarkeyBoy

  Hi, I know its unlikely but I was wondering if there is any way to get the comments (i.e. the bits after the ''') of a class or property..? I have managed to get a list of properties of a class using the PropertyInfo class but I cant find a way to get the comments / description.. I need it for a guide I am writing for the administrators of my site - it would be great if it could automatically update if new properties are added, so there is no need to worry about updating it in the future too much. Anyone know how to do this? Thanks in advance. Regards, Richard

• Question about Jboss deployment

  - by Manoj

  Hi All, I am new to Jboss and deployment of web applications etc. I have two different war files deployed on the same Jboss server. Further they also share some classes which read different properties based on the application settings (Let's call a common class as CommonClass.class which is present in App1.war and App2.war; CommonClass has a member "FIELD1", so both these war files have CommonClass.class each of which reads different properties, into CommonClass.FIELD1). But during run-time when I access FIELD1 in one application (App2.war-CommonClass.FIELD1) it has the value from another application (App1.war-CommonClass.FIELD1). Is there any way I can explicitly specify so that JBoss treats these classes and fields to be different? so that both these classes can exist in memory yet hold their respective correct values? Thanks a ton, Manoj

• How to remove iso 9660 from USB?

  - by a_m0d

  I have somehow managed to write an iso 9660 image onto my USB drive, which makes all my computer think that the device is actually a CD. I have tried various methods of removing this partition, but nothing seems to work. I have tried fdisk, which says $ fdisk -l /dev/sdb Cannot open /dev/sdb parted crashes when I try to use it on this device. I have even tried $ dd if=/dev/zero of=/dev/sdb but it just hangs with no output (either on screen or on disk). However, when I plug the USB in, it does mount, and I can view (but not edit) the files on it. edit: now the result is $ dd if=/dev/zero of=/dev/sdb dd: opening `/dev/sdb': Read-only file system I have also tried re-formatting it on Windows, but it gets to the end of the format process and then says "Couldn't format the drive".

• CSS-Specifity and CSS Inheritance (concrete question)?

  - by jens

  Hello, i would by thankful for an official link (and section) of the specification for CSS, that explains if: .one two h1 {color:green;font-family:arial;} /*case 1 */ .one two h1 {color:blue;} /*case 2*/ will result in (when evaluated by the browser) .one two h1 {color:blue;font-family:arial;} /*case 3*/ or will it be: .one two h1 {color:blue;} /*case 4*/ ==I have read a lot about inheritance, specifity, cascading etc but I still have not found for the given example which rules apply here. In regard to specifity both elements are equal in specifity the case2 will be the most specify one (as it is equal specific but the last one). But does specifity always apply to the whole selector with ALL properties defined. Or only the the properties that are are in "competition" (and declared in both). thanks!!!!

• UIScrollView strange zoom behavior when content is a UIView subclass

  - by sigsegv

  Hi, I'm experiencing the following: I created a UIView subclass with a CATiledLayer as backing layer by overriding the layerClass method. The layer properties (delegate, tileSize, etc) are set in the initWithFrame: method of the subclass. +(Class)layerClass { return [CATiledLayer class]; } -(id)initWithFrame:(CGRect)frame { if(self = [super initWithFrame:frame]) { renderer = [[MFPDFRenderer alloc]init]; tiledLayer = (CATiledLayer *)[self layer]; [tiledLayer setFrame:frame]; [tiledLayer setLevelsOfDetail:2]; [tiledLayer setLevelsOfDetailBias:3]; [tiledLayer setTileSize:CGSizeMake(512, 512)]; [tiledLayer setDelegate:renderer]; } return self; } Then I add an instance of said class as the content of an UIScrollView and set UIScrollView properties and implement the required delegate's methods. Everything works fine but when zooming the scroll view keep repositioning itself on its center. It's hardly noticeable when zooming in the center of the content, but unbearable otherwise. The same scroll view works fine when I use as (zoomable) content any other view such as an UIImageView or even a normal UIView with a CATiledLayer with the same properties and delegate of the subclass implementation as sublayer. When I check layer bounds and frame in the drawLayer:inContext: method of the delegate I get the following result as the zoom increase UIView with CATiledLayer as sublayer: 2010-04-03 21:05:33.499 Renderer[89293:4903] Layer: (0.000, 0.000) 320.000 x 460.000 2010-04-03 21:05:33.500 Renderer[89293:4903] Bounds: (0.000, 0.000) 320.000 x 460.000 2010-04-03 21:05:33.529 Renderer[89293:4903] Layer: (0.000, 0.000) 320.000 x 460.000 2010-04-03 21:05:33.534 Renderer[89293:4903] Bounds: (0.000, 0.000) 320.000 x 460.000 Custom subclass: 2010-04-03 21:04:15.969 Renderer[88957:4903] Layer: (0.000, 0.000) 657.910 x 945.746 2010-04-03 21:04:15.970 Renderer[88957:4903] Bounds: (0.000, 0.000) 320.000 x 460.000 2010-04-03 21:04:17.428 Renderer[88957:4903] Layer: (-0.000, 0.000) 766.964 x 1102.510 2010-04-03 21:04:17.429 Renderer[88957:4903] Bounds: (0.000, 0.000) 320.000 x 460.000 [...] 2010-04-03 21:19:10.388 Renderer[92573:4903] Layer: (-0.000, 0.000) 905.680 x 1301.916 2010-04-03 21:19:10.388 Renderer[92573:4903] Bounds: (0.000, 0.000) 320.000 x 460.000 I suppose that's the culprit or at least another symptom. I can add that I get the same erratic behavior if my subclass is built over a standard CALayer with the same renderer. Any suggestion will be appreciated!

• Reflecting derived classes in C#

  - by rook

  Let's assume there's a class with a virtual property (let's call it 'P'). It's overridden in a deriving class. Now I want to use something like this: obj.GetType().GetProperty("P") to get info about the overriding property. This search is ambigous, because there are two "P" properties (base and override). So I typed: obj.GetType().GetProperty("P", BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance) It returns the overriding "P" only, but what if I can't guess in compile time if there's an override at all? The latter call would return null. The case is even more complicated, if the hierarchy of inheritance is bigger. In other words, I want to get the 'top-most' override available, otherwise - the base property. What is the cleanest way to achieve the aim? Only one I know at the moment is to go through all properties and check name and declaring type.

• In WPF RichTextBox, does overriding of Underline/Strikethrough work?

  - by Daniel Earwicker

  In a WPF RichTextBox, the effective style of a Run of text is a result of combining the properties defined on the Run with the properties it "inherits" from the enclosing Paragraph and finally the styles on the Document. So you can set FontWeight to Bold at any of those levels. You can also set it Bold on the Paragraph and then switch it to Normal (override it) for a specific Run. However, underline and strikethrough are different. They are items that can optionally appear in a list of TextDecorations, which is a property of Inline (and hence Run) and of Paragraph, but not of Document. And you can switch on Underline in the Paragraph, and it gets inherited so that all Runs within that Paragraph default appear underlined by default. Is it possible to switch it off underline in a specific Run? i.e. is there a way to insert an entry into the list of TextDecorations which would mean "Don't underline", thus overriding the Paragraph's setting?

• Get drive label in C#

  - by Rick

  When I use System.IO.DriveInfo.GetDrives() and look at the .VolumeLabel property of one of the drives, I see "PATRIOT XT", which is indeed the drive's volume label. If I open "My Computer", instead I see "TrueCrypt Traveler Disk", and I can't seem to find any way to programmatically retrieve that value as none of the DriveInfo properties hold that value. I also tried querying the information via WMI's Win32_LogicalDisk, but no properties contained that value there either. So any idea what the label My Computer uses is called, and more importantly, how to programmatically retrieve it? Thanks

• .Net reflection to get developers comments about class / property etc?

  - by ClarkeyBoy

  Hi, I know its unlikely but I was wondering if there is any way to get the comments (i.e. the bits after the ''') of a class or property..? I have managed to get a list of properties of a class using the PropertyInfo class but I cant find a way to get the comments / description.. I need it for a guide I am writing for the administrators of my site - it would be great if it could automatically update if new properties are added, so there is no need to worry about updating it in the future too much. Anyone know how to do this? Thanks in advance. Regards, Richard

• Convert/Cast base type to Derived type

  - by user102533

  I am extending the existing .NET framework class by deriving it. How do I convert an object of base type to derived type? public class Results { //Framework methods } public class MyResults : Results { //Nothing here } //I call the framework method public static MyResults GetResults() { Results results = new Results(); //Results results = new MyResults(); //tried this as well. results = CallFrameworkMethod(); return (MyResults)results; //Throws runtime exception } I understand that this happens as I am trying to cast a base type to a derived type and if derived type has additional properties, then the memory is not allocated. When I do add the additional properties, I don't care if they are initialized to null. How do I do this without doing a manual copy?
