  • List of Users and Role using Membership Provider

    - by Jemes
    I’m trying to produce a view to show a list of users and their role using the built in membership provider. My model and controller are picking up the users and roles but I’m having trouble displaying them in my view. Model public class AdminViewModel { public MembershipUserCollection Users { get; set; } public string[] Roles { get; set; } } Controller public ActionResult Admin() { AdminViewModel viewModel = new AdminViewModel { Users = MembershipService.GetAllUsers(), Roles = RoleService.GetRoles() }; return View(viewModel); } View Inherits="System.Web.Mvc.ViewPage<IEnumerable<Account.Models.AdminViewModel>>" <table> <tr> <td>UserName</td> <td>Email</td> <td>IsOnline</td> <td>CreationDate</td> <td>LastLoginDate</td> <td>LastActivityDate</td> </tr> <% foreach (var item in Model) { %> <tr> <td><%=item.UserName %></td> <td><%=item.Email %></td> <td><%=item.IsOnline %></td> <td><%=item.CreationDate %></td> <td><%=item.LastLoginDate %></td> <td><%=item.LastActivityDate %></td> <td><%=item.ROLE %></td> </tr> <% }%> </table>

  • How do I insert this subclass into my code?

    - by BamsBamx
    This is a very noob question so I hope you can help me with this... This is my built code: public class PantallaOpciones extends PreferenceActivity { private SharedPreferences preferences; @Override public void onCreate(Bundle savedInstanceState) { preferences = PreferenceManager.getDefaultSharedPreferences(this); findPreference("speechkeycode").setOnPreferenceClickListener(keycodedialog); Preference.OnPreferenceClickListener keycodedialog = new Preference.OnPreferenceClickListener(){ public boolean onPreferenceClick(Preference preference){ keycodedialog(); return false; }}; } private void keycodedialog(){ final Dialog dialog = new Dialog(this); dialog.setContentView(R.layout.keycodedialog); dialog.setTitle("Speech keycode"); final TextView keypresstext = (TextView) findViewById(R.id.keypresstext); Button savekeycode = (Button) dialog.findViewById(R.id.btnsavekeycode); savekeycode.setOnClickListener(new OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); Button resetkeycode = (Button) dialog.findViewById(R.id.btnresetvalue); resetkeycode.setOnClickListener(new OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); dialog.show(); } Okay, now I want to add this code to dialog: public boolean onKeyDown(int keyCode, KeyEvent event) { //SOME STUFF return super.onKeyDown(keyCode, event); } So I want to listen to a keypress when dialog is opened and show the keycode of hardware press by using textview.settext()... The question is: how do I insert public boolean onKeyDown into the dialog??? Thanks in advance!! :)

  • Howcome some C++ functions with unspecified linkage build with C linkage?

    - by christoffer
    This is something that makes me fairly perplexed. I have a C++ file that implements a set of functions, and a header file that defines prototypes for them. When building with Visual Studio or MingW-gcc, I get linking errors on two of the functions, and adding an 'extern "C"' qualifier resolved the error. How is this possible? Header file, "some_header.h": // Definition of struct DEMO_GLOBAL_DATA omitted DWORD WINAPI ThreadFunction(LPVOID lpData); void WriteLogString(void *pUserData, const char *pString, unsigned long nStringLen); void CheckValid(DEMO_GLOBAL_DATA *pData); int HandleStart(DEMO_GLOBAL_DATA * pDAta, TCHAR * pLogFileName); void HandleEnd(DEMO_GLOBAL_DATA *pData); C++ file, "some_implementation.cpp" #include "some_header.h" DWORD WINAPI ThreadFunction(LPVOID lpData) { /* omitted */ } void WriteLogString(void *pUserData, const char *pString, unsigned long nStringLen) { /* omitted */ } void CheckValid(DEMO_GLOBAL_DATA *pData) { /* omitted */ } int HandleStart(DEMO_GLOBAL_DATA * pDAta, TCHAR * pLogFileName) { /* omitted */ } void HandleEnd(DEMO_GLOBAL_DATA *pData) { /* omitted */ } The implementations compile without warnings, but when linking with the UI code that calls these, I get a normal error LNK2001: unresolved external symbol "int __cdecl HandleStart(struct _DEMO_GLOBAL_DATA *, wchar_t *) error LNK2001: unresolved external symbol "void __cdecl CheckValid(struct _DEMO_MAIN_GLOBAL_DATA * What really confuses me, now, is that only these two functions (HandleStart and CheckValid) seems to be built with C linkage. Explicitly adding "extern 'C'" declarations for only these two resolved the linking error, and the application builds and runs. Adding "extern 'C'" on some other function, such as HandleEnd, introduces a new linking error, so that one is obviously compiled correctly. The implementation file is never modified in any of this, only the prototypes.

  • How to split up levels? (cocos2d,box2d,iphone) to save CPU and memory?

    - by cocos2dbeginner
    Hi, so I'm going to create large levels. But there's a problem: There's much unseen space (it's a jump'n run like mario bros.) and this will use memory + cpu. so how could I split up my levels? I'm using Box2D+ cocos2d for iphone. Any ideas? Mayby just set the visible property to NO? But it would be still in the memory :(. But what with the box2d bodies? Destroy and recreate them would be to heavy for the FPS, because I have physics built in which should not be recreated. Should I make fix points where i want to split the level up, than if the player is 200 px away it should preload it. and if the player is 200 px away from the last part of the level I unload it. But there would be the problem with the physics, because on the start of the level it has a unique movement and later if i destroy and recreate it it would do the same. but i don't want that. other ideas?

  • password is auto-completed despite setting redisplay=false in JSP (Struts)

    - by lmcgowin
    So I have a web application on Tomcat, built on top of Struts 1.1. Here is a snippet of my JSP, it's a login. <html:form action = "LoginAction" focus = "username"> <table> <tr><td align = "right">User name: </td> <td><html:text property = "username"/> </td></tr> <tr><td align = "right">Password: </td><td><html:password property = "password" redisplay = "false"/></td></tr> </table> </html:form> Snippet from struts-html-1.1.tld: <tag> <name>password</name> <tagclass>org.apache.struts.taglib.html.PasswordTag</tagclass> <attribute> <name>redisplay</name> <required>false</required> <rtexprvalue>true</rtexprvalue> </attribute> </tag> Resulting HTML: Having trouble getting this to post as code but the relevant part is an input tag of type 'password' with no reference to redisplay, autocomplete, etc. It is my understanding that the redisplay element should be passed through Struts to appear in the HTML.

  • PHP5 getrusage() returning incorrect information?

    - by Andrew
    I'm trying to determine CPU usage of my PHP scripts. I just found this article which details how to find system and user CPU usage time (Section 4). However, when I tried out the examples, I received completely different results. The first example: sleep(3); $data = getrusage(); echo "User time: ". ($data['ru_utime.tv_sec'] + $data['ru_utime.tv_usec'] / 1000000); echo "System time: ". ($data['ru_stime.tv_sec'] + $data['ru_stime.tv_usec'] / 1000000); Results in: User time: 29.53 System time: 2.71 Example 2: for($i=0;$i<10000000;$i++) { } // Same echo statements Results: User time: 16.69 System time: 2.1 Example 3: $start = microtime(true); while(microtime(true) - $start < 3) { } // Same echo statements Results: User time: 34.94 System time: 3.14 Obviously, none of the information is correct except maybe the system time in the third example. So what am I doing wrong? I'd really like to be able to use this information, but it needs to be reliable. I'm using Ubuntu Server 8.04 LTS (32-bit) and this is the output of php -v: PHP 5.2.4-2ubuntu5.10 with Suhosin-Patch 0.9.6.2 (cli) (built: Jan 6 2010 22:01:14) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies

  • Is ther a Designer for MFC in Visual Studio like for windows forms in .NET?

    - by claws
    Hello, I'm a .NET programmer. I've never developed anything in MFC. Currently I had to write a C++ application (console) for some image processing task. I finished writing it. But the point is I need to design GUI also for this. Well, there won't be anything complex. Just a window with few Buttons, RadioButtons, Check Boxes, PicturesBox & few sliders. thats it. I'm using VS 2008 and was expecting a .NET style form designer. Just to test, I created a MFC project (with all default configuration) and these files were created by default: ChildFrm.cpp MainFrm.cpp mfc.cpp mfcDoc.cpp mfcView.cpp stdafx.cpp Now, I'm unable to find a Designer. There is no View Designer. I've opened all the above *.cpp and in the code editor right clicked to see "Designer View". ToolBox is just empty because I'm in code editor mode. When I built the project. This is the window I get. How to open a designer?

  • RequestBuilder timeouts and browser connection limits per domain.

    - by WesleyJohnson
    This is specifically about GWT's RequestBuilder, but should apply to general XHR as well. My company is having me build a near realtime chat application over HTTP. Yes, I do realize there are better ways to do chat aplications, but this is what they want. Eventually we want it working on the iPad/iPhone as well so flash is out, which rules out websockets and comet as well, I think? Anyway, I'm running into issues were I've set GWT's RequestBuilder timeout to 10 seconds and we get very random and sporadic timeouts. We've got error handling and emailing on the server side and never get any errors, which suggests the underlying XHR request that RequestBuilder is built on, never gets to the server and times out after 10 seconds. We're using these request to poll the server for new messages rather often and also for sending new messages to the server and also polling (less frequently) for other parts of application. What I'm afraid of is that we're running into the browsers limit on concurrent connections to the same domain (2 for IE by default?). Now my question is - If I construct a RequestBuilder and call it's send() method and the browser blocks it from sending until one of the 2 connections per domain is free, does the timeout still start while the request is being blocked or will it not start until the browser actually releases the underlying XHR? I hope that's clear, if not please let me know and I'll try to explain more.

  • Should i write my own forum? If my site has banning/PM/etc?

    - by acidzombie24
    I built a site from scratch (already done). It has banning, PM, comments, etc. The PMs and comments are done using markdown (like SO system). Should i write my own forum code or should i find one already made? What are reasons for or against writing my own? There are pros and cons for writing my own or using another software. But some cons keeping me from using another forum software is Multiple Logins: One for the site, one for separate forums. Need to Customization code: I'll need to change the toolbar in the forum software so i can access pages on the regular site. Look consistency: It may look drastically different from my site even after applying lots of css changes. Banning and User consistency. Users may be ban on site or on forums but not the other. users may select a different or multiple usernames on the forum instead of being forced to use the same username on both site and forum. What are reasons for or against writing my own and using forum software?

  • MS Office Excel Ribbon - Cannot change/hide Editing group in Home tab

    - by A9S6
    I have a .net addin for Excel. The addin creates the Ribbon UI for Excel 2007 and re-purposes some existing commands such as Cut, Copy, Paste, Sort etc. For Cut, Copy and Paste I am just overriding their OnAction value to call my own procedure when the buttons are clicked. But for Sort, Sort Asc and Sort Desc commands the case is a little different. When either of the Sort, Sort Asc or Sort Desc buttons are clicked, I want to get notified and then call the default functionality. This was possible in Excel 2003 commandsbars by calling the Execute() method on the CommandBarControl. In Excel 2007, there is a ExecuteMso() method to programmatically click a ribbon element but when the OnAction is overridden, this ExecuteMso() method just executes my own procedure and not the default functionality of that button. So I thought that I will HIDE the Sort buttons in the "Editing" group in Home tab and add my own Sort, Sort Asc and Sort Desc buttons to it. The buttons will call into my procedure first from where I will call the default behavior. Now the problem is that I am unable to change/hide the Editing group (idMso="GroupEditing"). Is this built-in group not editable? I can however HIDE the Clipboard and other groups(but can't add buttons to them). <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui"> <ribbon> <tabs> <tab idMso="TabHome"> <group idMso="GroupEditing" visible="false" /> </tab> </tabs> </ribbon> </customUI>

  • asp.net 3.5 app - can not load asemblies, "Strong name signature could not be verified", only when d

    - by hitsolutions
    Have developed an asp.net 3.5 application which consists of a we-site, some developed assemblies and some 3rd party assembles such as Telerik, Jayrock etc, all very much standard 3rd party apps. Created and built this app, tested on Win 2008 Eval running on a VM, all fine. Imagine my frustration when after installing on clients production Win 2008 server, that the app could not run and the error message was the "Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed ..." one. This was for all assembles in app (removed one and this kept popping up for a different assembly). Attempted to install on a machine on the network and received the same error. I am fairly baffled and a little freaked as I can not figure this out and time is rapidly running out. Have inspected all parts of server I know about (.NET, IIS7) but all seems fine. What could cause this? It sounds like there is a stricter security manifest on the production server - but where would I look and for what? It must be a group policy. only other item is that the machines are running Symantec ante-virus. The IT head is on hols so can't quiz him which is also frustrating - but as they say time waits for no man!

  • Set Renderbuffer Width and Height (Open GL ES)

    - by Josh Elsasser
    I'm currently experiencing an issue with an Open GL ES renderbuffer where the backing and width are are both set to 15. Is there any way to set them to the width of 320 and 480? My project is built up on Apple's EAGLView class and ES1Renderer, but I've moved it from the app delegate to a controller. I also moved the CADisplayLink outside of it (I update my game logic with the timestamp from this) Any help would be greatly appreciated. I add the glview to the window as follows: CGRect applicationFrame = [[UIScreen mainScreen] applicationFrame]; [window addSubview:gameController.glview]; [window makeKeyAndVisible]; I synthesize the controller and the glview within it. The EAGLView and Renderer are otherwise unmodified. Renderer Initialization: // Get the layer CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = TRUE; eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:FALSE], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; renderer = [[ES1Renderer alloc] init]; Render "resize from layer" Method - (BOOL)resizeFromLayer:(CAEAGLLayer *)layer { // Allocate color buffer backing based on the current layer size glBindRenderbufferOES(GL_RENDERBUFFER_OES, colorRenderbuffer); [context renderbufferStorage:GL_RENDERBUFFER_OES fromDrawable:layer]; glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_WIDTH_OES, &backingWidth); glGetRenderbufferParameterivOES(GL_RENDERBUFFER_OES, GL_RENDERBUFFER_HEIGHT_OES, &backingHeight); NSLog(@"Backing Width:%i and Height: %i", backingWidth, backingHeight); if (glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES) != GL_FRAMEBUFFER_COMPLETE_OES) { NSLog(@"Failed to make complete framebuffer object %x", glCheckFramebufferStatusOES(GL_FRAMEBUFFER_OES)); return NO; } return YES; }

  • Why might one app connect to SQL backend OK and a second app fail if they share the same connectionstring?

    - by hawbsl
    Trying to figure out a SQL connection error 26 in our app. We've got two closely related apps Foo and FooAddIn. Foo is a Winforms app built in VS2010 and runs fine and connects fine to our SQLExpress back end. FooAddIn is an Outlook AddIn which references Foo.exe and connects to the same SQL Express instance. Or rather, it doesn't connect, instead reporting: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Now, both apps share the same connectionstring and we've verified they really do share the same connectionstring. At this stage we're just testing from within the same developer machine, so the apps are on the same machine, going via the same VS2010 IDE. So a lot of the advice online for this error doesn't apply because the fact that Foo connects through to SQL Express tells us the database is there and available and can be reached. What else is there to check? One thing is that Foo and FooAddIn are running different runtime versions of System.Data (v2.0.50727 and v4.0.30319). Could that be a factor?

  • Rails: Obfuscating Image URLs on Amazon S3? (security concern)

    - by neezer
    To make a long explanation short, suffice it to say that my Rails app allows users to upload images to the app that they will want to keep in the app (meaning, no hotlinking). So I'm trying to come up with a way to obfuscate the image URLs so that the address of the image depends on whether or not that user is logged in to the site, so if anyone tried hotlinking to the image, they would get a 401 access denied error. I was thinking that if I could route the request through a controller, I could re-use a lot of the authorization I've already built into my app, but I'm stuck there. What I'd like is for my images to be accessible through a URL to one of my controllers, like: http://railsapp.com/images/obfuscated?member_id=1234&pic_id=7890 If the user where to right-click on the image displayed on the website and select "Copy Address", then past it in, it would be the SAME url (as in, wouldn't betray where the image is actually hosted). The actual image would be living on a URL like this: http://s3.amazonaws.com/s3username/assets/member_id/pic_id.extension Is this possible to accomplish? Perhaps using Rails' render method? Or something else? I know it's possible for PHP to return the correct headers to make the browser think it's an image, but I don't know how to do this in Rails... UPDATE: I want all users of the app to be able to view the images if and ONLY if they are currently logged on to the site. If the user does not have a currently active session on the site, accessing the images directly should yield a generic image, or an error message.

  • how does Cocoa compare to Microsoft, Qt?

    - by Paperflyer
    I have done a few months of development with Qt (built GUI programatically only) and am now starting to work with Cocoa. I have to say, I love Cocoa. A lot of the things that seemed hard in Qt are easy with Cocoa. Obj-C seems to be far less complex than C++. This is probably just me, so: Ho do you feel about this? How does Cocoa compare to WPF (is that the right framework?) to Qt? How does Obj-C compare to C# to C++? How does XCode/Interface Builder compare to Visual Studio to Qt Creator? How do the Documentations compare? For example, I find Cocoa's Outlets/Actions far more useful than Qt's Signals and Slots because they actually seem to cover most GUI interactions while I had to work around Signals/Slots half the time. (Did I just use them wrong?) Also, the standard templates of XCode give me copy/paste, undo/redo, save/open and a lot of other stuff practically for free while these were rather complex tasks in Qt. Please only answer if you have actual knowledge of at least two of these development environments/frameworks/languages.

  • Identical files from different servers. Why might IE 8 display them differently?

    - by jasongetsdown
    I'm working on a site that will go on my company's intranet. I developed it locally on my computer, checking it in different browsers and on colleague's computers, and when it was done I handed it off to IT. They put identical copies on a staging server, and on the production server. This is a site built only with html, javascript, and css. No server side scripting. It also uses a DWF viewer plugin from Autodesk. It is a single standalone page (not part of a CMS) that allows users to load drawings into the viewer and then click to see info from a database of space info saved in a series of js arrays (the space DB software spits out a js file with all the info listed in array literals, creating a crap ton of global variables - ugh, but I digress). When I followed their links (using IE 8) the version on the staging server looked as expected, but the layout is hosed on the version from the production server. Specifically, it seems like a div that is supposed to flow to the right of a div that is float: left is displaying below the floated div at full width, as though it was clear: left (which it is not). It also has the wrong height. I downloaded the files from each and they are identical to my local version. Frustrated, I cleared my browser's cache, restarted my computer, checked it on a colleague's computer who also has IE 8. All the same issue. Staging server good. Production server bad. Finally I uninstalled IE 8 and looked at it in IE 6. Both versions looked fine. So, to recap. Two different servers. No server side scripting. Identical files. One browser agrees they are identical, the other does not. What could cause this?

  • flex 4 release changes to application are not showing up.

    - by guacamoly
    I just took over a clients flex project and I can't get the app to reflect even a simple trace statement. Before I took over, the project was last successfully built using the Flash Builder Beta 2 environment/sdk. I have the latest release version of Flash Builder 4. Upon importing the project into FB4, I got a ton of errors. Most of them mostly because of the changes made to the sdk from beta2 to release. Some of the things I corrected: - mx namespace from library://ns.adobe.com/flex/halo to library://ns.adobe.com/flex/mx - video player skinning: a lot of the state names for the video player component had been changed, more required states had been added. also there were other video related component and property names that had to be updated. But I fixed all that and the application was finally able to compile (although with some warnings mostly of the duplicate variable type) The only thing now is that whatever change I make to the project doesn't get reflected in the build (debug or release). I changed existing traces, added additional traces. Nothing shows up. I even removed the applicationComplete property in the main.mxml. Everything still ran like nothing changed. Also I can't seem to debug the app. Whenever I try to debug.. flash builder says.. "Swf Application doesn't contain the required debugging information ... " Anyone have any idea how I need to even begin tackling all this? Any help or pointers would be greatly appreciated.

  • SELECT Statement without duplicate rows on the multiple join tables

    - by theBo
    I have 4 tables built with JOINS and I would like to SELECT DISTINCT rows on the setsTbl.s_id so they always show regardless if there's relational data against them or not!. This is what I have at present which displays the data but doesn't display all of but not the entire distinct row! SELECT setsTbl.s_id, setsTbl.setName, userProfilesTbl.no + ' ' + userProfilesTbl.surname AS Name, trainingTbl.t_date, userAssessmentTbl.o_id FROM userProfilesTbl LEFT OUTER JOIN userAssessmentTbl ON userProfilesTbl.UserId = userAssessmentTbl.UserId FULL OUTER JOIN trainingTbl ON userAssessmentTbl.tt_id = trainingTbl.tt_id RIGHT OUTER JOIN setsTbl ON trainingTbl.s_id = setsTbl.s_id WHERE (userProfilesTbl.st_id=@st_id AND userProfilesTbl.sh_id=@sh_id) AND (DATEPART(yyyy,t_date) = @y_date ) OR (userAssessmentTbl.o_id IS NULL) ORDER BY setName ASC, t_date ASC With this statement I get some of the rows (the ones with data against them) but as stated the s_id field does not return distinct.

  • Mulltiple configurations in Qt

    - by user360607
    Hi all! I'm new to Qt Creator and I have several questions regarding multiple build configurations. A side note: I have the QtCreator 1.3.1 installed on my Linux machine. I need to have two configurations in my Qt Creator project. The thing is that these aren't simply debug and release but are based on the target architecture - x86 or x64. I came across http://stackoverflow.com/questions/2259192/building-multiple-targets-in-qt-qmake and from that I went trying something like: Conf_x86 { TARGET = MyApp_x86 } Conf_x64 { TARGET = MyApp_x64 } This way however I don't seems to be able to use the Qt Creator IDE to build each of these separately (Build All, Rebuild All, etc. options from the IDE menu). Is there a way to achieve this - may be even show Conf_x86 and Conf_x64 as new build configurations in Qt Creator? One other thing the Qt I have is 64 bit so by default the target built using Qt Creator IDE will also be 64 bit. I noticed that the effective qmake call in the build step includes the following option '-spec linux-g++-64'. I also noticed that should I add '-spec linux-g++-32' in 'Additional arguments' it would override '-spec linux-g++-64' and the resulting target will be 32 bit. How can I achieve this by simply editing the contents of the .pro file? I saw that all these changes are initially saved in the .pro.user file but does doesn't suit me at all. I need to be able to make these configurations from the .pro file if possible. Any help will be appreciated. 10x in advance!

  • Partial class or "chained inheritance"

    - by Charlie boy
    Hi From my understanding partial classes are a bit frowned upon by professional developers, but I've come over a bit of an issue; I have made an implementation of the RichTextBox control that uses user32.dll calls for faster editing of large texts. That results in quite a bit of code. Then I added spellchecking capabilities to the control, this was made in another class inheriting RichTextBox control as well. That also makes up a bit of code. These two functionalities are quite separate but I would like them to be merged so that I can drop one control on my form that has both fast editing capabilities and spellchecking built in. I feel that simply adding the code form one class to the other would result in a too large code file, especially since there are two very distinct areas of functionality, so I seem to need another approach. Now to my question; To merge these two classes should I make the spellchecking RichTextBox inherit from the fast edit one, that in turn inherits RichTextBox? Or should I make the two classes partials of a single class and thus making them more “equal” so to speak? This is more of a question of OO principles and exercise on my part than me trying to reinvent the wheel, I know there are plenty of good text editing controls out there. But this is just a hobby for me and I just want to know how this kind of solution would be managed by a professional. Thanks!

  • SIlverlight Navigate: how does it work? How would you implement in f# w/o VS wizards and helpers?

    - by akaphenom
    After a nights sleep the problem can be stated more accurately as I have a 100% f# / silverlight implementation and am looking to use the built in Navigation components. C# creates page.xaml and page.xaml.cs um - ok; but what is the relationship at a fundamental level? How would I go about doing this in f#? The applcuation is loaded in the default module, and I pull the XAML in and reference it from the application object. Do I need to create instances / references to the pages from within the application object? Or set up some other page management object with the proper name value pairs? When all the Help of VS is stripped away - what are we left with? original post (for those who may be reading replies) I have a 100% silverlight 3.0 / f# 2.0 application I am wrapping my brain around. I have the base application loading correctly - and now I want to add the naigation controls to it. My page is stored as an embedded resource - but the Frame.Navigate takes a URI. I know what I have is wrong but here it is: let nav : Frame = mainGrid ? mainFrame let url = "/page1.xaml" let uri = new System.Uri(url, System.UriKind.Relative) ; nav.Navigate uri Any thoughts?

  • cocoa/c++ relative path to load resources

    - by moka
    Hi, I am currently working directly with cocoa for the first time, to built a screen saver. Now I came across a problem when trying to load resources from within the .saver bundle. I basically have a small c++ wrapper class to load .exr files using freeImage. That works as long as I use absoulte paths, but thats not very useful, is it? So basically I tried everything, putting the .exr file on the level of the .saver bundle itself, inside the bundles Resources folder and so on. Then I simply tried to load the .exr like this without success particleTex = [self loadExrTexture: "ball.exr"]; I also tried making it go to the .saver bundles location like this: particleTex = [self loadExrTexture: "../../../ball.exr"]; to maybe load the .exr from that location but without success. I then came across this: NSString * path = [[NSBundle mainBundle] pathForResource:@"ball" ofType:@"exr"]; const char * pChar = [path UTF8String]; which seems to be a common way to find resources in cocoa, but for some reason its emty in my case. any ideas about that? I really tried out anything that came to my mind without success so I would be glad about some input!

  • What exactly can "Full Control" with SharePoint Designer accomplish?

    - by Brian L.
    I've been brought in as an intern to develop a SharePoint site. My team won't authorize the budget for Visual Studio and I don't have physical or remote access to the SharePoint server (running Windows SharePoint Services 3.0 a.k.a. WSS) on the back-end. So what exactly can I do? I'm a pretty decent programmer when it comes to web technologies like PHP, JS and the obvious HTML and CSS. In an environment like this locked-down SharePoint though, I'm stumped trying to figure out how much control I have with MS's definition of "Full Control". If I figured out a way to write some C#, I'm pretty sure I could handle my own, but as I said no Visual Studio for me. Any good ideas of features that people will use on a site built with the limited functionality of WSS and SharePoint Designer with "Full Control"? Can I somehow manipulate the default Web Parts into something cool or useful? Are there Ajax tricks I can do to accomplish something on the back-end? Thanks in advance, I'm new to StackOverflow and very anxious to get involved here!

  • What's the best way of accessing a DRb object (e.g. Ruby Queue) from Scala (and Java)?

    - by Tom Morris
    I have built a variety of little scripts using Ruby's very simple Queue class, and share the Queue between Ruby and JRuby processes using DRb. It would be nice to be able to access these from Scala (and maybe Java) using JRuby. I've put together something Scala and the JSR-223 interface to access jruby-complete.jar. import javax.script._ class DRbQueue(host: String, port: Int) { private var engine = DRbQueue.factory.getEngineByName("jruby") private var invoker = engine.asInstanceOf[Invocable] engine.eval("require \"drb\" ") private var queue = engine.eval("DRbObject.new(nil, \"druby://" + host + ":" + port.toString + "\")") def isEmpty(): Boolean = invoker.invokeMethod(this.queue, "empty?").asInstanceOf[Boolean] def size(): Long = invoker.invokeMethod(this.queue, "length").asInstanceOf[Long] def threadsWaiting: Long = invoker.invokeMethod(this.queue, "num_waiting").asInstanceOf[Long] def offer(obj: Any) = invoker.invokeMethod(this.queue, "push", obj.asInstanceOf[java.lang.Object]) def poll(): Any = invoker.invokeMethod(this.queue, "pop") def clear(): Unit = { invoker.invokeMethod(this.queue, "clear") } } object DRbQueue { var factory = new ScriptEngineManager() } (It conforms roughly to java.util.Queue interface, but I haven't declared the interface because it doesn't implement the element and peek methods because the Ruby class doesn't offer them.) The problem with this is the type conversion. JRuby is fine with Scala's Strings - because they are Java strings. But if I give it a Scala Int or Long, or one of the other Scala types (List, Set, RichString, Array, Symbol) or some other custom type. This seems unnecessarily hacky: surely there has got to be a better way of doing RMI/DRb interop without having to use JSR-223 API. I could either make it so that the offer method serializes the object to, say, a JSON string and takes a structural type of only objects that have a toJson method. I could then write a Ruby wrapper class (or just monkeypatch Queue) to would parse the JSON. Is there any point in carrying on with trying to access DRb from Java/Scala? Might it just be easier to install a real message queue? (If so, any suggestions for a lightweight JVM-based MQ?)
