    - by Angela
    I have tried to do the following, but the web-service is NOT REST and does not take multi-part.

  • can you deploy cruise control .net as a web service/web app?

    - by Maslow
    I'm investigating the possibility of utilizing my web host as a cruise control.net build server. If I have access to MsBuild or can deploy msBuild and run it, it would be great. I can not however find any resources that would tell me if cruise control supports being run as a web service or web app. Is this type of deployment possible? If not could the UI (it's web-based I believe) control section sit on the web server and send requests to the actual build server?

  • Session state server saying extended class no serializable

    - by jenson-button-event
    I am storing an object in session state (using local session state server), class def is: [Serializable] public class ExtendedOAuth2Parameters : OAuth2Parameters but the service is still reporting: Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. [SerializationException: Type 'Google.GData.Client.OAuth2Parameters' in Assembly 'Google.GData.Client, Version=2.1.0.0, Culture=neutral, PublicKeyToken=04a59ca9b0273830' is not marked as serializable.] How to get around it?

  • RegularExpressionValidator - Windows ID Validation

    - by Albert
    I'd like to setup a RegularExpressionValidator to ensure users are entering valid windows IDs in a textbox. Specifically, I'd like to ensure it's any three capital letters (for our range of domains), followed by a backslash, followed by any number of letters and numbers. Does anyone know where I can find some examples of this type of validation...or can somebody whip one up for me? :)

  • Delphi Unit local variables - how to make each instance unique?

    - by Justin
    Ok, this, I'm sure is something simple that is easy to do. The problem : I've inherited scary spaghetti code and am slowly trying to better it when new features need adding - generally when a refactor makes adding the new feature neater. I've got a bunch of code I'm packing into a single unit which, in different places in the application, controls the same physical thing in the outside world. The control appears in several places in the application and operates slightly differently in each instance. What I've done is to create a unit with all of the features I need which I can simply drop, as a frame, into each form that requires it. Each form then uses the unit's interface methods to customise the behaviour for each instance. The problem within the problem : In the unit in question (the frame) I have a variable declared in the IMPLEMENTATION section - local to the unit. I also have a procedure, declared in the TYPE section which takes an argument and assigns that argument to the local variable in question - each form passes a unique variable to each instance of the frame/unit. What I want it to do is for each instance of the frame to keep its own version of that variable, different from the others, and use that to define how it operates. What seems to be happening, however, is that all instances are using the same value, even if I explicitly pass each instance a different variable. ie: Unit FlexibleUnit; interface uses //the uses stuff type TFlexibleUnit=class(TFrame) //declarations including procedure makeThisInstanceX(passMeTheVar:integer); private // public // end; implementation uses //the uses var myLocalVar; procedure makeThisInstanceX(passMeTheVar:integer); begin myLocalVar:=passMeTheVar; end; //other procedures using myLocalVar //etc to the end; Now somewhere in another Form I've dropped this Frame onto the Design pane, sometimes two of these frames on one Form, and have it declared in the proper places, etc. Each is unique in that : ThisFlexibleUnit : TFlexibleUnit; ThatFlexibleUnit : TFlexibleUnit; and when I do a: ThisFlexibleUnit.makeThisInstanceX(var1); //want to behave in way "var1" ThatFlexibleUnit.makeThisInstanceX(var2); //want to behave in way "var2" it seems that they both share the same variable "myLocalVar". Am I doing this wrong, in principle? If this is the correct method then it's a matter of debugging what I have (which is too huge to post) but if this is not correct in principle then is there a way to do what I am suggesting? Thanks in advance, Stack Overflow - you guys (and gals!) are legendary.

  • How to process audio in real time?

    - by user1756648
    I am giving some audio input through microphone. I recorded it in Audacity, it looks something like as shown below. I want to process this audio in real time. I mainly want to do this. 1) see real time audio amplitude vs time graph 2) perform some actions based on some thing (like if a specific type of hike is seen in audio, then do something, else do something else) Is there any python module or C library that can allow me to do this ?

  • UUID collision risk using different algorithms

    - by Diego Jancic
    Hi Guys, I have a database where 2 (or maybe 3 or 4) different applications are inserting information. The new information has IDs of the type GUID/UUID, but each application is using a different algorithm to generate the IDs. For example, one is using the NHibernate's "guid.comb", other is using the SQLServer's NEWID(), other might want to use .NET's Guid.NewGuid() implementation. Is there an above normal risk of ID collision or duplicates? Thanks!

  • Objective-C subclasses question

    - by Johannes Jensen
    I have a class called Level, which is a subclass of NSObject. Then I have a class called Level_1_1 which is a subclass of Level. Is it allowed to type like Level* aLevel = [Level_1_1 alloc]; instead of Level_1_1* theLevel = [Level_1_1 alloc]; ? :) I try it and I don't get any warnings, just wondering if it's okay to do?

  • jquery - targetting a select using $this

    - by Maureen
    I am trying to get individual selects (which have the same class as other selects) to respond to a .change function, however it only works on one of the selects. If you test out this code it will make more sense. Try to add a few "ON/OFF events", and then select "Specified Time" in the various selects. You'll see only the first one responds. Any ideas? Thanks! Please see the following code: $(document).ready(function() { var neweventstring = '<div class="event">Turns <select name="ONOFF"><option value="On">ON</option><option value="Off">OFF</option></select> at: <select name="setto" class="setto"><option>Select Time</option><option value="Sunrise">Sunrise</option><option value="Sunset">Sunset</option><option value="specifiedtime">Specified Time</option></select></div>'; $('#addmondaysevent').click(function () { $('#monday .events').append(neweventstring); }); $('.setto').change(function() { alert('The function is called'); if($("option:selected", this).val() =="specifiedtime"){ alert('If returns true'); $(this).css("background-color", "#cc0000"); $(this).after('<div class="specifictime"><input type="text" value="00" style="width:30px"/> : <input type="text" value="00" style="width:30px"> <select name="ampm"><option value="AM" selected>AM</option><option value="PM">PM</option></select></div>') } }); }); And my HTML: <div id="monday"> <h2>Mondays</h2> <div class="events"> <div class="event"> Turn <select name="ONOFF"> <option value="On">ON</option> <option value="Off">OFF</option> </select> at: <select name="setto" class="setto"> <option>Select Time</option> <option value="Sunrise">Sunrise</option> <option value="Sunset">Sunset</option> <option value="specifiedtime">Specified Time</option> </select> </div> [<a id="addmondaysevent">Add an ON/OFF event</a>] </div> </div>
