Configure Service Reference… - Object reference is not set to an instance of an object

阅读更多关于 Configure Service Reference… - Object reference is not set to an instance of an object

问题 I am working with Visual Studio 2013 , .NET4.5 . Originally I was WCF service consumer but due to lack of resources in team that deals with subsystem I took over development of both sides of WCF service. So I got Code of the WCF service that I need to call and now trying to plug it in to debug it on my local system. Issue: Service that I need to call works on localhost fine I can get wsdl and browse to it. However when I try in Visual Studio 2013 'Configure Service Reference...' and Try to

Accessing local variables in the ASM Java library

阅读更多关于 Accessing local variables in the ASM Java library

问题 I'm trying to invoke a local variable when inserting a method. Thus far, I'm able to get the local variable in a Node but am having trouble actually accessing anything. Here is my insertion stuff (it's very scrappy, I've been at this for a while and design stopped being my main priority some time ago): final ClassReader reader = new ClassReader("revel/reflection/test/SomeClass"); final ClassNode classNode = new ClassNode(); reader.accept(classNode, 0); for(final MethodNode mn : (List

NodeJS and MAMP running on local machine. Is it possible?

阅读更多关于 NodeJS and MAMP running on local machine. Is it possible?

问题 Is it possible to have NodeJS and MAMP running together on the same machine? If so how would i achieve this? Note: I can run them separately just not together. I assume its down to my NodeJS using the "localhost" as well as MAMP. 回答1: You can setup Proxy and a host. for example create node01.example.com in Hosts. Then Go to Advanced and enter the following in "Customized virtual host general settings" ServerAlias node01.example.com <Location /> ProxyPass http://127.0.0.1:3000/

AIR(Flex) local socket connection

阅读更多关于 AIR(Flex) local socket connection

问题 When connecting from a local AIR/Flex application to a local application (c++) using sockets do you still need a socket policy file? If you do, is there an easy way to load the policy file without sending the policy from the local application you are trying to connect to? side note: I am writing both applications. 回答1: When connecting to another application on the localhost using sockets, you do not need to use a socket policy. 来源： https://stackoverflow.com/questions/1526982/airflex-local

How can I know how my app was launched on Mac OS?

阅读更多关于 How can I know how my app was launched on Mac OS?

问题 I've got a problem, and have been looking for a solution for a long time. I made a application which has an option which will launch the app automatically when the system starts using Launch Services. If application is launched by the user (ie. opening the .app) I want to do something. If application is launch by Launch Services when the system starts I want to do another thing. So I need to know how the app was launched: by the System (Launch Services loading the app when the computer turns

Hadoop - Reducer is waiting for Mapper inputs?

阅读更多关于 Hadoop - Reducer is waiting for Mapper inputs?

问题 as explained in the title, when i execute my Hadoop Program (and debug it in local mode) the following happens: 1. All 10 csv-lines in my test data are handled correctly in the Mapper, the Partitioner and the RawComperator(OutputKeyComparatorClass) that is called after the map-step. But the OutputValueGroupingComparatorClass's and the ReduceClass's functions do NOT get executed afterwards. 2. My application looks like the following. (due to space constraints i omit the implementation of the

Local functions calling each other

阅读更多关于 Local functions calling each other

问题 I have two functions that occasionally call each other, and they are local to a module that uses them to build another function. The module is somewhat similar to this piece of code: local function iseven(n) if n == 1 then return false else return isodd(n - 1) end end local function isodd(n) if n == 1 then return true else return iseven(n - 1) end end local evenOrOdd = function(n) return iseven(n) and "Even" or "Odd" end return evenOrOdd The problem is, when calling evenOrOdd from another

OpenGL + SDL rotation around local axis

阅读更多关于 OpenGL + SDL rotation around local axis

I've been working on a semi flight simulator. What I am trying to do is use a pitch roll and yaw to rotate an object. I have already looked online a lot, and although they explain what the problem is I have no idea how to implement the solution. So for example I do: glRotatef(yaw,0,1,0); glRotatef(pitch,1,0,0); The yaw doesn't act properly, the pitch will work fine. And from what I have been reading it seems that the objects local axis has been changed so I need to find the object's new local axis and rotate around that. So I tried that with something like: newpitch=pitch/57.29 VectorA(0,cos

Effective ip->location query

阅读更多关于 Effective ip->location query

问题 I have two tables: one is ip_group_city from ipinfodb.com containing ip_start numbers for determining location of IPs, and other is "visits" with information about web site visitor containing column 'ip'. I need to select top 10 region_code (from ip_group_city) by checking region_code for each IP from "visits" table. Right now I'm loading all IPs from "visits" into an array and using that IP info to query the ip_group_city by: SELECT region_code FROM ip_group_city WHERE ip_start <= INET_ATON

Large XML Files and Pagination, is it possible?

阅读更多关于 Large XML Files and Pagination, is it possible?

问题 The problem When opening very large XML files locally, on your machine, it's almost a certainty that it will take an age for that file to open - it can often mean your computer locks down because it thinks it's not responding. This is an issue if you serve users XML backups of rather complex databases or systems they use - the likehood of them being able to open large backups, let alone use them, is slim. Is pagination possible? I use XSLT to present readable backups to users. In this same
