  • Android Broadcast Address

    - by Eef
    Hey, I am making a Client Server application for my Android phone. I have created a UDP Server in Python which sits and listens for connections. I can put either the server IP address in directly like 192.169.0.100 and it sends data fine. I can also put in 192.168.0.255 and it find the server on 192.169.0.100. Is it possible to get the broadcast address of the network my Android phone is connected to? I am only ever going to use this application on my Wifi network or other Wifi networks. Cheers

  • COM on Windows7 and Visual Studio

    - by vikasde
    I registered a COM dll (under administrator) using regsvr32, which I want to use in Visual Studio 2008 (under administrator) for my project in Windows 7. Now, when I try to use the interfaces and classes from the COM, then I can't see any of the methods. When I use the object browser to view the COM classes, then I can see that they are all empty. However when I use the same COM on windows XP using VS2008, then all methods are suddenly available. Does anybody know why this is happening and how to get this working under Windows 7?

  • Android HelloWorld Build Path error

    - by BahaiResearch.com
    On my Mac I installed Eclipse, the SDK and created a new project, then hit build expecting to see my first helloworld app. I got the error "the project cannot be built until build path errors are fixed". After going thru all the path-like options in Preferences, I noticed that on the tab "Java Build Path" the "Google APIs [Android 2.2]" option did not have its check box checked. Checking it made the problem go away. It works now and I can see the app in the Emulator Have I not set up my environment correctly? I used all the defaults in Eclipse and the Android SDK.

  • Does Android support near real time push notification

    - by j pimmel
    I recently learned about the ability of iPhone apps to receive nearly instantaneous notifications to apps. This is provided in the form of push notifications, a bespoke protocol which keeps an always on data connection to the iPhone and messages binary packets to the app, which pops up alerts incredibly quickly, between 0.5 - 5 seconds from server app send to phone app response time. This is sent as data - rather than SMS - in very very small packets charged as part of the data plan not as incoming messages. I would like to know if using Android there is either a similar facility, or whether it's possible to implement something close to this using Android APIs. To clarify I define similar as: Not an SMS message, but some data driven solution As real time as is possible Is scalable - ie: as the server part of a mobile app, I could notify thousands of app instances in seconds I appreciate the app could be pull based, HTTP request/response style, but ideally I don't want to to be polling that heavily just to check for notification .. besides which it's like drip draining the data plan.

  • Getting a Target to run BEFORE anything else runs when building from Visual Studio

    - by damageboy
    Hi, I'm trying to get a one-time costly target to run only when building a certain top-level project (that has many dependencies). I have no problem on getting this working from plain msbuild / command line build. I do this with setting and InitialTargets on the project, or alternatively with < BeforeBuild /. The tricky part is with Visual Studio. When I build the same project from VS. VS runs the dependencies before even invoking my .csproj, so my target (which affects how the other projects are built) doesn't get to run until they have already been built. Is there someway to force VS to run a target before invoking the dependencies? I'm currently working around this, by running the same costly target from my most low-level project (the one that get's always built...) by using: Condition=" $(BuildingInsideVisualStudio) " Any ideas on how to get this done "properly"? Again, I'm looking for a solution that will work FROM VS.

  • Flash causing crash in embeded browser

    - by Lodle
    For my work project we recently switched from visual studio 2008 to 2010 and we use an embedded instance of firefox to render webpages. The only problem we are having is that flash seems to crash the application. It seems that instead of linking dynamically to the runtime it needs its using the new 2010 one and is having issue with new and delete. Any ideas on how to fix instead of switching back to 2008?

  • Visual Studio Pre build events and batch set

    - by helloworld922
    Hi, I'm trying to create call a batch file which sets a bunch of environment variables prior to building. The batch file looks something like this (it's automatically generated before-hand to detect ATI Stream SDK or NVidia CUDA toolkit): set OCL_LIBS_X86="%ATISTREAMSDKROOT%libs\x86" set OCL_LIBS_X64="%ATISTREAMSDKROOT%libs\x86_64" set OCL_INCLUDE="%ATISTREAMSDKROOT%include" However, the rest of the build doesn't seem to have access to these variables, so when I try to reference $(OCL_INCLUDE) in the C/C++GeneralAdditional include directories, it will first give me warning that environment variable $(OCL_INCLUDE) was not found, and when I try to include CL/cl.hpp the compile will fail with: fatal error C1083: Cannot open include file: 'CL/cl.hpp': No such file or directory I know that I could put these variables into the registry if I wanted to access them from the visual studio GUI, but I would really prefer not to do this. Is there a way to to get these environment variables to stick after the pre-build events? I can't reference $(ATISTREAMSDKROOT) directly because the project must be able to build for both ATI Stream and NVidia Cuda.

  • C# / Visual Studio: production and test code placement

    - by Patrick Linskey
    Hi, In JavaLand, I'm used to creating projects that contain both production and test code. I like this practice because it simplifies testing of internal code without artificially exposing the internals in a project's published API. So far, in my experiences with C# / Visual Studio / ReSharper / NUnit, I've created separate projects (i.e., separate DLLs) for production and test code. Is this the idiom, or am I off base? If this idiomatically correct, what's the right way to deal with exposing classes and methods for test purposes? Thanks, -Patrick

  • Error C2491 on C source with Visual studio 8

    - by Tobia
    i'm really noob in C. I just need to compile a ANSI C source to get a dll. During compilation i get this error: C2491: 'SelectML': definition of dllimport function not allowed Where SelectML is a public function with this definition: int CALLINGCONV SelectML(WORD fid, int nSlot) { WORD SW; int x; BYTE pSend[2]; pSend[0]=(BYTE)((fid&0xff00)>>8); pSend[1]=(BYTE)(fid&0x00ff); x=SendAPDUML(hCards[nSlot],APDU_SELECT,2,0,pSend,0,&SW); if (x!=C_OK) return x; if (SW!=0x9000) return SW; return C_OK; } I'm sure the C source is good, maybe it is just a Visual Studio configuration...

  • Building Android app from ant via Hudson - chicken and egg problem

    - by Eno
    When using an Android-generated ant build file, the file references your SDK installation via an sdk.dir property inside the local.properties files which is generated by "android update project -p .". The comments in build.xml suggest that local.properties should NOT be checked into version control. BUT, when you run your build from Hudson, it does a fresh checkout of your code from version control, hence local.properties does not exist and subsequently the build fails without sdk.dir being set. So its kind of chicken and egg problem. As a workaround I have checked local.properties into version control for now (nobody else will use it) but I was curious as to how other developers had tackled this problem ?

  • How to gain greater control of network packets on Android

    - by mauvehead
    I'm looking to design an application that will require some deep control over IP packets. Looking over the reference guide on the developers site at Android I see very limited control over packets from java.net:SocketOptions and java.net:DatagramPacket. Specifically I'm looking to control the individual bits within the packet to set TCP Flags, SYN/ACK/RST, and so forth. Based on the docs I am assuming I cannot do this within the Java API provided by Android and I'm guessing I'll have to do it some other way? Anyone have any insight on this?

  • Include Files using Wildcard into a folder in Visual Studio

    - by quip
    I am using <ItemGroup> <EmbeddedResource Include="..\..\resources\hbm\*.hbm.xml" /> </ItemGroup> to include a bunch of xml files into my C# project. Works fine. But, I don't want them in the "root level" of my project, I would rather see them in a subfolder in my project. For example, this file is included into a Mapping folder in Visual Studio: <ItemGroup> <EmbeddedResource Include="Mapping\User.hbm.xml" /> </ItemGroup> That's what I want for my *.hbm.xml files. I can't figure out how to do it and still keep my wildcard *.hbm.xml part and also keep the actual files in a different directory. I've looked at MSDN's doc on MSBUILD and items, but no luck.

  • Android P2P Multiplayer game (with a) XMPP/Google talk b) JXTA peerdroid c) other way)

    - by Kristof
    Hi, I am an android developer and I made some board games. Now i want to make some of my board games multiplayer. I don't want to create and host my own web service, so i thought about P2P. The first thing i found was the XMPP protocol, however it's not real P2P, but if i can use the existing google talk service, i'm ready to go. Is this possible while using your existing google account without interfering with the normal working of your google talk client? Then i heard about JXTA, a real P2P solution, and it's already ported from J2ME to Android (http://code.google.com/p/peerdroid/). Maybe i am overcomplexing things here (as i do sometimes) I just want to know the easiest way to do simple P2P for a boardgame. All your opinions are welcome! Thanks in advance

  • Visual Studio 2010 Formatting

    - by Rosarch
    I have plenty of experience with Eclipse, and now I'm trying out Visual Studio 2010. I find its formatting somewhat counter-intuitive. Here are some things I'm trying to figure out: Is there a way to select all text and format/indent it properly, like SHIFT+A SHIFT+I in Eclipse? Why is it that when I type a line like if (n == 0) {, as soon as I type the opening brace, the text cursor is moved to the beginning of the line? Is this some productivity speedup I'm failing to see? When I hit ENTER after the aforementioned line, I'd like the closing brace to be put in place automatically for me. How can I do this? I've looked for hotkey documentation, and it's helped a bit, but this still feels clunky to me.

  • How to use client side code in Visual studio ASP.NET

    - by Robert
    I am a quite new to web development and I am trying to do some small form updates without causing a postback. For example making a control visible when a drop down list is changed. I have so far come across some features that achieve this like the RequiredFieldValidator inside an update panels. However, these are specific to a single task. What are my options to achieve these client side updates in Visual Studio? At the moment I don't know any JavaScript, so I would prefer another solution if it exists.
