• TFS Check in rules

  - by NPehrsson

  Hi I'm out of setting up an TFS server and I want to set some check-in rules. I for example want to be able to set rules about method lenght, complexity and so on, I found NDepend very convenient can I somehow use NDepend to run some rules on the files trying to check in. I also want to be able to bypass the rules sometimes. Are there any blogs or discussions around this, if it wont work with NDepend are there any other tools or ways I can use?

• Check for live Data Source Name Before proceeding

  - by n_kips

  Would it be ok to get a CF app to check for a valid database before proceeding to process that request? This is because there may be instances where the database server may be down or being upgraded, hence an error comes when a db dependant request is made. If there is no connection to the db server, the user can be safely redirected to a safe page. Or can cfcatch work? How can this check be done? Thank you.

• How to check WCF generated client is compatible with service at runtime

  - by Schneider

  I realise that WCF and services in general are meant to be loosely coupled. But I have a requirement that my client app can check whether an given WCF endpoint contains a service that matches its generated client code. In other words I need to check for a compatible service. Obviously I could have a method that returns a manually maintained version number, but I would prefer not to have to write my own meta data system if WCF can do something out of the box.

• Want to check fields for data fast.

  - by Tom

  We have a database setup that consists of two parts: a static structure, and dynamic additions. For each database, the dynamic can be different, and sometimes we don't have data for all the dynamic fields. Rigt now, we check for empties by looking at the total count of records in the entire table, but we want to move to a more refined method of checking for empties if possible. Is it possible to quickly check through several hundred fields and see which ones are empty and which ones are populated?

• How to check if service is enabled with launchd

  - by spartygw

  I can't figure out how to check from within C/C++ if a service is enabled via launchd. I know I can use launchctl from the command line and am currently executing ' launchctl list myServiceName ' from fork/exec. I've found that boostrap_look_up() might be the way to check this but I can't find enough documentation to condense this down to a simple example. Can you shed light on this? All I need is a small function to test if my service is actually registered and available.

• Using YQL and Jquery to check URL validity

  - by user102533

  The answer in this post http://stackoverflow.com/questions/2119680/use-jquery-to-check-if-a-url-on-another-domain-is-404-or-not shows how to use YQL in Jquery to check if URL is valid or not. However, I can't get this to work for me. The only difference I can think of is that my URL is a text file (http://mycrossdomain.com/sometext.txt) and not HTML.I think the YQL query needs to be adjusted accordingly. Any help is appreciated.

• Check exact match of a word in a list of words

  - by Flake

  I want to check if a word is in a list of words. word = "with" word_list = ["without", "bla", "foo", "bar"] I tried if word in set(list), but it is not yielding the wanted result due to the fact in is matching string rather than item. That is to say, "with" is a match in any of the words in the word_list but still if "with" in set(list) will say True. What is a simpler way for doing this check than manually iterate over the list?
