  • Make a target run once at the Solution level in MSBuild

    - by Chandam
    I need a set of tasks that need to be executed exactly once for the entire solution. This will run tasks that will modify each project to run a separate set of tasks for each project. We had done this earlier using a separate project to the solution which had the solution level tasks, but we want to move away from that. Has anyone done this or does anyone have any suggestions on how to implement this?

    - by den-javamaniac
    Hi. Can anyone point out how to check if a select query returns non empty result set? For example I have next query: SELECT * FROM service s WHERE s.service_id = ?; Should I do something like next: ISNULL(SELECT * FROM service s WHERE s.service_id = ?) to test if result set is not empty?

  • Internal classes with ADO.NET Entity Framework

    - by Regent
    I'm using Entity Framework for creation of my Data Access Layer and I want for all of my classes to be internal. I know it is possible to manually assign it manually in the designer for each class. But looks like it also requires to set internal modifier for each single property in every class! I have about 30+ entities and it will be a huge work to do. Do you know any ideas how to set a 'default access' for the entire model?

  • The fundamentals of Hash tables?

    - by kylex
    I'm quite confused about the basic concepts of a Hash table. If I were to code a hash how would I even begin? What is the difference between a Hash table and just a normal array? Basically if someone answered this question I think all my questions would be answered: If I had 100 randomly generated numbers (as keys), how would I implement a hash table and why would that be advantageous over an array? Psuedo-code or Java would be appreciated as a learning tool...

  • UpdateLayout throwing an ambigious exception

    - by Ouais
    the stack trace displays my method's name then "external code" then app_unhandledexception method, I'm developing within VS2008 SP1 for silverlight on firefox and windows 7(if that makes a difference). the weird thing is, the updatelayout method is called elsewhere and it generates no exception there, that said, if I put the method within a try-catch clause, it doesn't catch the exception, so if anyone has an idea, I'd appreciate it.

  • Need to write a daemon in linux, not sure what to use C++ or C

    - by Bluescrod
    Hello everyone, I have a little problem picking the right language to write my daemon, I am confused between C and C++, I want to use C++ because it is more expanded than C, but I want to use C because it is the starting point of everything in linux, I want to go for C++ as I have many resources about it, so, does it make any difference if I pick C++ instead of C? and what I will have good if I learn C more? I feel like if I go into C++ I will cover C within C++... Regards

  • php joomla session lifetime settings

    - by jtanmay
    I have searched through the google and also joomla forums but didn't got what exactly I was looking for. My main purpose is to set the joomla session live for ever. Many forums says its not good to keep a higher value (security issues) but I don't want to consider that right now. My question is : What if I set the session lifetime value to "0" (Zero), will the session be active for ever? or the user will NOT be able to login completely? Thanks, Tanmay

  • Regex vs. string:find() for simple word boundary

    - by user576267
    Say I only need to find out whether a line read from a file contains a word from a finite set of words. One way of doing this is to use a regex like this: .*\y(good|better|best)\y.* Another way of accomplishing this is using a pseudo code like this: if ( (readLine.find("good") != string::npos) || (readLine.find("better") != string::npos) || (readLine.find("best") != string::npos) ) { // line contains a word from a finite set of words. } Which way will have better performance? (i.e. speed and CPU utilization)

  • CSS - How can I center a div within a div?

    - by Spines
    I have an outer div that is 800px wide. I have an inner div that could be anywhere from 200 to 600px wide. I know how to center the inner div within the outer one if I set the inner one to have a specific width, but how do I center it since its a variable width? Is there a way to set the div to only be the width of the elements inside of it, rather than having it expand to fill its containing div?

  • What's the purpose of the unnamed namespace?

    - by bbazso
    In a .cpp file, if I decare a constant as follows: namespace { const int UDP_PORT_MIN = 1024; const int UDP_PORT_MAX = 65535; } vs. just: const int UDP_PORT_MIN = 1024; const int UDP_PORT_MAX = 65535; What's the difference between these two? I often see constant definitions declared in an unnamed namespace, so I was wondering what's the purpose of the unnamed namespace in this context?
