  • Check for active connection in NHibernate

    - by Dofs
    I have a system with a few different databases, and I would like to check if a certain database is down, and if so display a message to the user. Is it possible in NHibernate to check if there is an active connection to the database, without having to request data and then catch the exception?

  • PHP - Check for whitespace at beginning of string

    - by ITg
    I need to use preg_match to check that only a-z0-9. is used (including full stop(.)). I don't want to replace anything. My problem is that it doesn't notice white space at beginning of a string. Also, if anyone knows how to check there is no two full stops in a row, I would be very grateful. What I have so far: ("/[^a-z0-9.]+$/",$request) Thanks !

  • 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.

  • Check console output in NUnit

    Is it possible to check what was written to console or a log file with NUnit? I have some legacy code where the only indication of correctness is the console output, so I want to be able to check that against expected values.

  • 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?

  • 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.

  • does != nil check for 0x0?

    - by 4thSpace
    I have a custom class and check that a property isn't 0x0 by doing: if(myinstance.someproperty != nil){ //do something } However, even if someproperty is 0x0, I still go into the conditional. someproperty is of another class type. Is there some other way to check this?

  • check if a URI exists?

    - by noname
    How do I check if a URI exists with PHP? I guess it will return an error code and I can check it before I use file_get_contents, because if I use file_get_contents on a link that doesn't exist, it gives me an error.

  • 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?

  • Android: Conversion to Dalvik format failed: Unable to execute dex: null

    - by Adam Haile
    I'm trying to use the SmugFig SmugMug API on Android. It was designed for J2SE I would imagine, so I'm not sure it will even work on Android, but I figured it was worth trying as opposed to trying to create my own API. When I load the project though, I get the following error: Conversion to Dalvik format failed: Unable to execute dex: null It doesn't say what package it fails on, just "Android Packaging Problem", but it did not do this before I added SmugFig and it's dependency JARS to the build path. Where should I look? Or does this mainly me that it just won't work with those libraries?

  • Objective-C how to check if a string is null

    - by norskben
    SO I wish to check to see if the item in my array [clientDataArray objectForKey:@"ClientCompany"] is nil. temp = [clientDataArray objectForKey:@"ClientCompany"]; if (temp != [NSNull null]) infofieldCompany.text = temp; So far I have been able to achieve this through the above code, but it does give me the warnings warning: 'NSArray' may not respond to'-objectForKey:' warning: comparison of distinct Objective-C types 'struct NSNull *' and 'struct NSString *' lacks a cast My main interest is the second warning, but the first warning also interest me. How should I adapt my above code?

  • jQuery getJSON response null for Firefox, works for IE

    - by user186106
    $.getJSON(service + "/GetJobTags", { tag: "a" }, function(json) { $.each(json, function(i,val) { alert(val.Title); }); }); It calls: http://127.0.0.1:20087/ClientService.svc/GetJobTags?tag=a This is probably of note, the service is running on a different port to the client application, which is on: http://127.0.0.1:32017/index.htm Firefox says HTTP 200 OK but the response data is null (and it highlights in red in Firebug). In IE it works fine, and the server is returning json. Is this a permissions problem? Do I need to use JSONP?

  • jQuery UI sortable('cancel') - this.helper is null

    - by Kerry
    I am trying to disable a sortable element from sorting when it has been double clicked. When I try to disable it, even without a condition, it gives me the error 'this.helper is null'. $('.roundedBox:first', division).sortable({ start: function( event, ui ) { if( true === true ) { $(this).sortable('cancel'); } $(this).parent().data( 'sorting', true ); }, stop: function() { $(this).parent().data( 'sorting', false ); }, items: '.department', update: function() {}, placeholder: 'department-placeholder' }) Any ideas on how I can do this? I don't need it to be this method. Literally anything thing that stops it will work. The problem is, sorting starts on a single click, but I have another action bound to double click. If it's double clicked, I don't want it to drag.

  • Column cannot be added because its CellType property is null exception

    - by niko
    Hi, I have trouble with the following piece of code. When I go through with the debugger I get an exception when it comes to the following line: dgvCalls.Columns.Insert(1, msisnnColumn); I get an exception: Column cannot be added because its CellType property is null. Oddly, I created the same procedure for some other DataGridViews and it worked fine. if (!(dgvCalls.Columns.Contains("DirectionImage"))) { directionIconColumn = new DataGridViewImageColumn(); directionIconColumn.Name = "DirectionImage"; directionIconColumn.HeaderText = ""; dgvCalls.Columns.Insert(0, directionIconColumn); directionIconColumn.CellTemplate = new DataGridViewImageCell(); } if (!(dgvCalls.Columns.Contains("msisndColumn"))) { msisnnColumn = new DataGridViewColumn(); msisnnColumn.Name = "msisndColumn"; msisnnColumn.HeaderText = "Klic"; dgvCalls.Columns.Insert(1, msisnnColumn); msisnnColumn.CellTemplate = new DataGridViewTextBoxCell(); } Any suggestions?
