  • 3D Screensaver interfering with WPF application (Windows XP)

    - by Andrew Keith
    I have a fairly large application that uses WPF for its user interface. I recently found an unusual defect regarding 3D screensavers. The 3D screensavers 3D FlowerBox,3D Flying Objects,3D Pipes,3D Text causes 1 of my WPF windows to disappear when the screensaver activates. Other screensavers are fine. My application only encounters this problem on Windows XP. I have some experience with DirectX. When a 3D screensavers activates, the d3d device context will be switched to exclusive mode. I reckon that WPF has trouble restoring the device context when the device switches back to cooperative mode (hence why its only affecting windows XP) Has anyone seen such a scenario occur before ? Is there a remedy for the problem ? Windows XP SP3, DirectX 9.0c, .NET 3.5

  • cheap way to scale a rails application

    - by VP
    I have an application, that is becoming big, but until now, its not giving me a good revenue. That means, short money to re-invest on that. In this scenario, i found a way to make a "cheap distributed rails" deployment. I've got 4 VPS. All of them are in the same physical server. I added a load balance server running HAproxy in one dedicated VPS. There i pointed my virtual ip address where my domain name is associated. Behind this HAproxy i have more two VPS running my rails APP, passenger and memcache. Both apps servers are looking to the same database server, my 4th VPS. So with $44/month, i mounted a distributed environment. It won't be my final choice, but now, that the budget is short, is that a good way to deploy a rails application? Any pros or cons? It worth my $44/month?

  • Silverlight MergedDictionaries and subclassing of Application

    - by mikeymo
    We have subclassed the Silverlight Application class to add some additional functionality and then use this in multiple projects. The problem is that the Resources defined in App.xaml do not seem to get loaded. Has anyone else seen this and/or have some insight? Here are the contents of App.xaml (note: the application starts and runs fine but then chokes when it looks for a Resource) <myNS:ApplicationBase xmlns:myNS="clr-namespace:Corp.XYZ.Infrastructure.Silverlight.Core;assembly=Corp.XYZ.Infrastructure.Silverlight.Core" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Corp.XYZ.BMW.App" > <myNS:ApplicationBase.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources/AlternateControlStyles/StandardExpander.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </myNS:ApplicationBase.Resources>

  • How do I define and standardize units in my 3D app?

    - by Omega
    I'm starting to design my object graph for an OpenGL ES 1.1 on Android. What's advisable when it comes to actually drawing my triangles when it comes to controlling their size? Should I store all the vertices in units relative to each other and then multiply them by a value I pass during a draw(GL10 gl)? Would this approach have any impact when it comes time to do frustum culling?

  • Updating the launcher icon at run-time

    - by david
    Is it possible to update the launcher icon dynamically? Currently it seems that it can only be set statically at build time using the android:icon attribute in the AndroidManifest.xml file. For example, to display a unique icon based on the device's location? Is this something that can be achieved using aliases? If so, can an alias's launcher icon be enabled/disabled dynamically?

  • iphone/ipad application - taking screen shot

    - by satyam
    I successfully implemented an application that works on ipad as well as on iphone. In that I provided option to user to send the screen shot of the application as mail attachment. Even that is functioning well. But my code is taking screen shot irrespective of orientation. The image i'm getting is always in portrait mode. I want to take the screen shot depending on the orientation of ipad/iphone and send the image as attachment. I'm using following code to take the screen shot. UIGraphicsBeginImageContext(screenWindow.frame.size); [screenWindow.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

  • How to use application config file in C#?

    - by badpanda
    I am trying to use a config file in my C# console application. I created the file within the project by going New -- Application Configuration File, and naming it myProjectName.config. My config file looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="SSDirectory" value="D:\Documents and Settings\****\MyDocuments\****" /> </appSettings> </configuration> The code to access it looks like this: private FileValidateUtil() { sSDirFilePath = ConfigurationSettings.AppSettings["SSDirectory"]; if (sSDirFilePath == null) Console.WriteLine("config file not reading in."); } Can anyone lend a hint as to why this is not working? (I am getting the error message.) Thanks!! badPanda

  • Securing WinForms Application suggestions

    - by Sarah Fordington
    I've been looking for a simple key/license system for our users. Its partly to stop piracy (avoid users from sharing the application around) and the other half to track the number of 'licensed users' we have. I have already read a few good suggestions on SO but I'm curious as to how people have implemented the 30 day evaluation criteria. Do you generate a key that stores the date somewhere and do a comparison each time or is it a little more complicated - deleting the file/removing the registry shouldn't deactivate. Are there any example implementations out there that can give me a head start? The irony is that our PM doesn't want to license a third-party system to do it for us. This is for a Windows Forms application.

  • Lightweight PHP server to bundle with application?

    - by munchybunch
    Does there exist some sort of PHP server that can be bundled with a locally-deployed application? It sounds wonky, but the end result is I can't use a remote web server to do anything. Clients will be downloading a package, and the plan is to use a Java backend that reads from a flat file. The flat file contains settings and is modified through a GUI written in HTML/JS, and this is where the server would come in. The forms in HTML should be able to submit to the server, which does a simple file write to the flat file. Is there any simple, lightweight server that has that simple feature? When running the executable for the application, it would start the installation process for the server before moving the web GUI files to the appropriate locations. Note that I'm doing this for a client, so I can't quite change the reqs and would rather not discuss their effectiveness. I would be ever thankful if people had suggestions for the server though!

  • How can I pass a Visual Studio project's assembly version to another project for use in a post-build

    - by Coder7862396
    I have a solution with 2 projects: My Application 1.2.54 (C# WinForms) My Application Setup 1.0.0.0 (WiX Setup) I would like to add a post-build event to the WiX Setup project to run a batch file and pass it a command line parameter of My Application's assembly version number. The code may look something like this: CALL MyBatchFile.bat "$(fileVersion.ProductVersion($(var.My Application.TargetPath)))" But this results in the following error: Unhandled Exception:The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj Error: The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj I would like to be able to pass "1.2.54" to MyBatchFile.bat somehow.

  • Authkit - deferring action to HTTP response to client application

    - by jon
    Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

  • Launch application from a browser

    - by Goro
    Hello, Is it possible to launch an application from a browser? I am not talking about opening a file from a browser (like open a PDF with Adobe Reader), but rather opening a new (blank) instance of an application that is installed on the user's machine. Hypothetical situation: User browses a website that lists computers that can be managed via RDP. He clicks on a link to 192.168.1.10, that link opens Microsoft RDP client (mstsc.exe) with that ip address already filled out. I am talking strictly about Windows universe. Is that thing even doable outside of ActiveX and IE? Is it wise to attempt this in IE with ActiveX ? Thanks a lot,

  • Bluetooth service problem

    - by hara
    hi I need to create a custom bluetooth service and I have to develop it using c++. I read a lot of examples but I didn't success in publishing a new service with a custom UUID. I need to specify a UUID in order to be able to connect to the service from an android app. This is what i wrote: GUID service_UUID = { /* 00000003-0000-1000-8000-00805F9B34FB */ 0x00000003, 0x0000, 0x1000, {0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB} }; SOCKET s, s2; SOCKADDR_BTH sab if (WSAStartup(MAKEWORD(2, 2), &wsd) != 0) return 1; printf("installing a new service\n"); s = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM); if (s == INVALID_SOCKET) { printf ("Socket creation failed, error %d\n", WSAGetLastError()); return 1; } memset (&sab, 0, sizeof(sab)); sab.addressFamily = AF_BTH; sab.port = BT_PORT_ANY; sab.serviceClassId = service_UUID; if (0 != bind(s, (SOCKADDR *) &sab, sizeof(sab))) { printf ("bind() failed with error code %d\n", WSAGetLastError()); closesocket (s); return 1; } int result=sizeof(sab); getsockname(s,(SOCKADDR *) &sab, &result ); printSOCKADDR_BTH(sab); if(listen (s, 5) == 0) printf("listen() is OK! Listening for connection... :)\n"); else printf("listen() failed with error code %d\n", WSAGetLastError()); printf("waiting connection"); for ( ; ; ) { int ilen = sizeof(sab2); s2 = accept (s, (SOCKADDR *)&sab2, &ilen); printf ("accepted"); } if(closesocket(s) == 0) printf("closesocket() pretty fine!\n"); if(WSACleanup () == 0) printf("WSACleanup() is OK!\n"); return 0; When i print the SOCKADDR_BTH structure retrieved with get getsockname i get an UUID that is not the mine. Furthermore if i use the UUID read from getsockname to connect the Android application the connection fails with this exception: java.io.IOException: Service discovery failed Could you help me?? Thanks!

  • How to get right values from Views touch event

    - by Pinker
    I have a problem with implementing touch events on GLSurfaceView. Views size is 1280x696, because of android (tablet) status bar at bottom with soft keys, time etc.., (screen resolution is 1280x800), but OnTouchListener is receiving touch events with coords [646.0,739.0], and thus my gluunproject method fails to return correct values is there any way to return events that respect these boundaries? or how should I recalculate the position?

  • Getting Path (context root) to the Application in Restlet

    - by Chad Gorshing
    I am needing to get the application root within a Restlet resource class (it extends ServerResource). My end goal is trying to return a full explicit path to another Resource. I am currently using getRequest().getResourceRef().getPath() and this almost gets me what I need. This does not return the full URL (like http://example.com/app), it returns to me /resourceName. So two problems I'm having with that, one is it is missing the schema (the http or https part) and server name, the other is it does not return where the application has been mounted to. So given a person resource at 'http://dev.example.com/app_name/person', I would like to find a way to get back 'http://dev.example.com/app_name'. I am using Restlet 2.0 RC3 and deploying it to GAE.

  • Sqlalchemy layout with WSGI application

    - by TheDude
    I'm working on writing a small WSGI application using Bottle and SqlAlchemy and am confused on how the "layout" of my application should be in terms of SqlAlchemy. My confusion is with creating engines and sessions. My understanding is that I should only create one engine with the 'create_engine' method. Should I be creating an engine instance in the global namespace in some sort of singleton pattern and creating sessions based off of it? How have you done this in your projects? Any insight would be appreciated. The examples in the documentation dont seem to make this entirely clear (unless I'm missing something obvious). Any thoughts?
