  • What Color is the Windows' System.Control? (Visual Studio Design View)

    - by jp2code
    In Visual Studio Design View, the selection of Form Colors in the Properties Pane are selectable from the "Custom", "Web", and "System" tabs. Of course, the color number can be used, too. When the "System" Tab is selected, the colors in the list depend on what type of Theme the Computer User has set on the PC. I'd like to stick with this, but I need to know how to "read in" the colors. I have controls that I create "on-the-fly" or often need to change a color back after getting the person's attention using a blink/flicker technique. How do I get the list of System Theme colors? Most forms have a BackColor that defaults to "Control", which looks like a very light gray under Windows 7, running the default Windows 7 Theme. I've managed to grab a color by physically reading the ARGB value in code, but I'd rather have a way to access the colors by their Theme Name, if that can be done. public Form1() { Color cControl = this.BackColor; Console.WriteLine(cControl.Name); // there is not always a name! } Does anyone know what I'm talking about?

  • Mis-spelling in the .NET configuration system, a design flaw?

    - by smwikipedia
    I just wrote some .NET code to get connection string from the config file. The config file is as below: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="key1" value="hello,world!"/> </appSettings> <connectionStrings> <add name="conn1" connectionString="abcd"/> </connectionStrings> </configuration> .NET Framework provide the following types to get the connection string: 1- ConnectionStringsSection : stands for the config section containing several connection strings 2- ConnectionStringSettingsCollection : stands for the connection string collection 3- ConnectionStringSettings : stands for a certain connection string. .NET Framework also provide the following types to get the App Settings: 4- AppSettingsSection 5- KeyValueConfigurationCollection 6- KeyValueConfigurationElement Compare 2 to 5, 3 to 6, why are there extra "s" in ConnectionStringSetting[s]Collection and ConnectionStringSetting[s]? This mis-spelling is really mis-leading. I think it's a design flaw. Has anyone noticed that?

  • C#: at design time, how can I reliably determine the type of a variable that is declared using var?

    - by Cheeso
    I'm working on a completion (intellisense) facility for C# in emacs. The idea is, if a user types a fragment, then asks for completion via a particular keystroke combination, the completion facility will use .NET reflection to determine the possible completions. Doing this requires that the type of the thing being completed, be known. If it's a string, it has a set of known methods; if it's an Int32, it has a separate set of methods, and so on. Using semantic, a code lexer/parser package available in emacs, I can locate the variable declarations, and their types. Given that, it's straightforward to use reflection to get the methods and properties on the type, and then present the list of options to the user. The problem arrives when the code uses var in the declaration. How can I reliably determine the actual type used, when the variable is declared with the var keyword? Just to be clear, I don't need to determine it at runtime. I want to determine it at "Design time". So far the best idea I have is: extract the declaration statement, eg var foo = "a string value"; concatenate a statement foo.GetType(); dynamically compile the resulting C# fragment it into a new assembly load the assembly into a new AppDomain, run the framgment and get the return type. unload and discard the assembly This sounds awfully heavyweight, for each completion request in the editor. Any better ideas out there?

  • How can i design a DB where the user can define the fields and types of a detail table in a M-D rela

    - by Simon
    My application has one table called 'events' and each event has approx 30 standard fields, but also user defined fields that could be any name or type, in an 'eventdata' table. Users can define these event data tables, by specifying x number of fields (either text/double/datetime/boolean) and the names of these fields. This 'eventdata' (table) can be different for each 'event'. My current approach is to create a lookup table for the definitions. So if i need to query all 'event' and 'eventdata' per record, i do so in a M-D relaitionship using two queries (i.e. select * from events, then for each record in 'events', select * from 'some table'). Is there a better approach to doing this? I have implemented this so far, but most of my queries require two distinct calls to the DB - i cannot simply join my master 'events' table with different 'eventdata' tables for each record in in 'events'. I guess my main question is: can i join my master table with different detail tables for each record? E.g. SELECT E.*, E.Tablename FROM events E LEFT JOIN 'E.tablename' T ON E._ID = T.ID If not, is there a better way to design my database considering i have no idea on how many user defined fields there may be and what type they will be.

  • Need a design approach or suggestion for a simple structure using Servlet.

    - by akshay
    Hi I have to design such that whenever user pass a query I process it using servlet and then call the js page to draw the chart 1 user writes a query on a page 2 the page call the servelt class public class MyServlet extends Httpservlet implements DataSourceServlet {..... return data The user see a beautiful string like this.. google.visualization.Query.setResponse......... /Tiger'},{v:80.0}, {v:false}]}]}}); 3 when the user hits on different html page myhtml.js it draws the chart. I want the Myservlet class itself call the myhtml.js page and draw the chart directly. and want to eliminate the beautiful string google.visualization.Query.setResponse......... /Tiger'},{v:80.0}, {v:false}]}]}}); from coming on user's browser What should i do? I tried using functions to call another page like request dispatcher(), redirect() calling myhtml.js page directly after myservlet process the query results. But i get the result like this google.visualization.Query.setResponse......... /Tiger'},{v:80.0}, {v:false}]}]}}); and the entire myhtml.js code page below it on the browsers that to without the chart been draw. Is there anyway to element the beautiful string from coming on clients browser and only show them the chart been drawn ? :) This is the small tutorial i am following http://code.google.com/apis/visualization/documentation/dev/dsl_get_started.html

  • What would be the Better db design for the old db structure?

    - by yawok
    i've a old database where i store the data of the holidays and dates in which they are celebrated.. id country hdate description link 1 Afghanistan 2008-01-19 Ashura ashura 2 Albania 2008-01-01 New Year Day new-year the flaws in the above structure is that, i repeat the data other than date for every festival and every year and every country.. For example, I store a new date for 2009 for ashura and afghanistan .. I tried to limit the redundancy and split the tables as countries (id,name) holidays (id, holiday, celebrated_by, link) // celebrated_by will store the id's of countries separated by ',' holiday_dates (holiday_id, date, year) // date will the full date and year will be as 2008 or 2009 Now i have some problems with the structure too.. consider that i store the holiday like Independence day , its common for more countries but will have different dates. so how to handle this and and the link will have to be different too.. And i need to list the countries which celebrates the same holiday and also when i describe about a single holiday i need to list all the other holidays that country would be celebrating.. And the most of all , i already have huge amount of data in the old tables and i need to split it to the new one once the new design is finalized... Any ideas?

  • Puppet - Possible to use software design patterns in modules?

    - by Mike Purcell
    As I work with puppet, I find myself wanting to automate more complex setups, for example vhosts for X number of websites. As my puppet manifests get more complex I find it difficult to apply the DRY (don't repeat yourself) principle. Below is a simplified snippet of what I am after, but doesn't work because puppet throws various errors depending up whether I use classes or defines. I'd like to get some feed back from some seasoned puppetmasters on how they might approach this solution. # site.pp import 'nodes' # nodes.pp node nodes_dev { $service_env = 'dev' } node nodes_prod { $service_env = 'prod' } import 'nodes/dev' import 'nodes/prod' # nodes/dev.pp node 'service1.ownij.lan' inherits nodes_dev { httpd::vhost::package::site { 'foo': } httpd::vhost::package::site { 'bar': } } # modules/vhost/package.pp class httpd::vhost::package { class manage($port) { # More complex stuff goes here like ensuring that conf paths and uris exist # As well as log files, which is I why I want to do the work once and use many notify { $service_env: } notify { $port: } } define site { case $name { 'foo': { class 'httpd::vhost::package::manage': port => 20000 } } 'bar': { class 'httpd::vhost::package::manage': port => 20001 } } } } } That code snippet gives me a Duplicate declaration: Class[Httpd::Vhost::Package::Manage] error, and if I switch the manage class to a define, and attempt to access a global or pass in a variable common to both foo and bar, I get a Duplicate declaration: Notify[dev] error. Any suggestions how I can implement the DRY principle and still get puppet to work? -- UPDATE -- I'm still having a problem trying to ensure that some of my vhosts, which may share a parent directory, are setup correctly. Something like this: node 'service1.ownij.lan' inherits nodes_dev { httpd::vhost::package::site { 'foo_sitea': } httpd::vhost::package::site { 'foo_siteb': } httpd::vhost::package::site { 'bar': } } What I need to happen is that sitea and siteb have the same parent "foo" folder. The problem I am having is when I call a define to ensure the "foo" folder exists. Below is the site define as I have it, hopefully it will make sense what I am trying to accomplish. class httpd::vhost::package { File { owner => root, group => root, mode => 0660 } define site() { $app_parts = split($name, '[_]') $app_primary = $app_parts[0] if ($app_parts[1] == '') { $tpl_path_partial_app = "${app_primary}" $app_sub = '' } else { $tpl_path_partial_app = "${app_primary}/${app_parts[1]}" $app_sub = $app_parts[1] } include httpd::vhost::log::base httpd::vhost::log::app { $name: app_primary => $app_primary, app_sub => $app_sub } } } class httpd::vhost::log { class base { $paths = [ '/tmp', '/tmp/var', '/tmp/var/log', '/tmp/var/log/httpd', "/tmp/var/log/httpd/${service_env}" ] file { $paths: ensure => directory } } define app($app_primary, $app_sub) { $paths = [ "/tmp/var/log/httpd/${service_env}/${app_primary}", "/tmp/var/log/httpd/${service_env}/${app_primary}/${app_sub}" ] file { $paths: ensure => directory } } } The include httpd::vhost::log::base works fine, because it is "included", which means it is only implemented once, even though site is called multiple times. The error I am getting is: Duplicate declaration: File[/tmp/var/log/httpd/dev/foo]. I looked into using exec, but not sure this is the correct route, surely others have had to deal with this before and any insight is appreciated as I have been grappling with this for a few weeks. Thanks.

  • split virtualization design based on environment or server role?

    - by Dan
    I'm setting up the server environment for a new software development group, which will include 4 test environments. These are web applications, so each environment will have an application server and a database server. I'm planning on buying two physical servers (e.g. 6-core CPU each with 12GB or so of RAM), and I'm thinking virtualization is appropriate here. With that in mind, I've thought of a couple ways that I could organize the virtualization strategy: - Separated by server role: Server 1 has all the application servers, each in their own guest VM. Server 2 has all the databases. OR - Separated by environment: Server 1 has a VM for two of the environments, with the VM containing both the app server and the database server. Server 2 would also contain two test environments, with the same style (app server and database in same VM). The advantages I see with all the app servers on one server and all the databases on another server is that I could probably be more efficient with the database server (one instance running multiple databases). But the other option seems easier to manage (archives/restorations would be contained in a single VM). Any recommendations? TIA.

  • A design for watching IPTV anywhere in the house?

    - by Carlos
    I'm currently getting TV and internet via IP to my house. The service comes into an ISP-supplied Router (ST585) which is in turn connected to an IPTV box. I need to replace the router, as it's port forwarding seems to be broken, so I was thinking of getting a box with an IGMP proxy. I once mistakenly got a non-IGMP box, with the result that the internet worked, but the IPTV didn't. The trouble is, I have no idea how to set up the IPTV part of the installation. I do have a copy of the ST585 configuration, but it doesn't look anything like the Cisco stuff that I learned about at CCNA. What are the steps necessary to reproduce the IGMP setup? I was thinking of WireSharking the communications on the network, but I suppose I'd need a hub for that? As a bonus, since the packets are coming in with the TV signal, is it possible to mess with the IGMP setup so I can watch TV anywhere in the house?

  • how to design network for connectivity between private and corporate LANs?

    - by maruti
    there is a bunch of servers connected to shared storage in a private LAN (10.x.x.x). this privateLAN is managed by a windows server (DHCP, DNS and directory services) these hosts need to be from outside of the datacenter Eg. Remote desktop. can the NIC2 on each of the hosts be connected to the other public LAN (compromising speed or security? what are improtant considerations: additional hardware? like switches? routing&DNS software? currently available hardware : Dell Powerconnect 6224 switch .... planning this for storage network. software: windows 2003 server for DHCP, DNS, A/D ? would it be more flexible to use Linux distributions like IPCOP, Untangle etc? all that I am looking for is good isolation between private and other networks, avoid DHCP, DNS, AD clashes.

  • On Ubuntu, how to design a monitor to run a process when a file is written to a directory?

    - by J G
    I want to run a process when a file is written to a directory on Ubuntu. I understand I can write a monitor to do this. (ie not an event based trigger but a 'monitor'). To implement this - other than writing a for loop of infinite duration in C that polls the directory - what steps would you take to implement this? What steps would you take to implement a monitor on Ubuntu that runs a process (another application) when a file is written to a directory? (The reason that you'd do this is the that process writing the file is under a limited set of permissions (eg tomcat6) but the executed process (an existing software package) needs root (ie to run a process in a chroot jail))

  • C# Proposal: Compile Time Static Checking Of Dynamic Objects

    - by Paulo Morgado
    C# 4.0 introduces a new type: dynamic. dynamic is a static type that bypasses static type checking. This new type comes in very handy to work with: The new languages from the dynamic language runtime. HTML Document Object Model (DOM). COM objects. Duck typing … Because static type checking is bypassed, this: dynamic dynamicValue = GetValue(); dynamicValue.Method(); is equivalent to this: object objectValue = GetValue(); objectValue .GetType() .InvokeMember( "Method", BindingFlags.InvokeMethod, null, objectValue, null); Apart from caching the call site behind the scenes and some dynamic resolution, dynamic only looks better. Any typing error will only be caught at run time. In fact, if I’m writing the code, I know the contract of what I’m calling. Wouldn’t it be nice to have the compiler do some static type checking on the interactions with these dynamic objects? Imagine that the dynamic object that I’m retrieving from the GetValue method, besides the parameterless method Method also has a string read-only Property property. This means that, from the point of view of the code I’m writing, the contract that the dynamic object returned by GetValue implements is: string Property { get; } void Method(); Since it’s a well defined contract, I could write an interface to represent it: interface IValue { string Property { get; } void Method(); } If dynamic allowed to specify the contract in the form of dynamic(contract), I could write this: dynamic(IValue) dynamicValue = GetValue(); dynamicValue.Method(); This doesn’t mean that the value returned by GetValue has to implement the IValue interface. It just enables the compiler to verify that dynamicValue.Method() is a valid use of dynamicValue and dynamicValue.OtherMethod() isn’t. If the IValue interface already existed for any other reason, this would be fine. But having a type added to an assembly just for compile time usage doesn’t seem right. So, dynamic could be another type construct. Something like this: dynamic DValue { string Property { get; } void Method(); } The code could now be written like this; DValue dynamicValue = GetValue(); dynamicValue.Method(); The compiler would never generate any IL or metadata for this new type construct. It would only thee used for compile type static checking of dynamic objects. As a consequence, it makes no sense to have public accessibility, so it would not be allowed. Once again, if the IValue interface (or any other type definition) already exists, it can be used in the dynamic type definition: dynamic DValue : IValue, IEnumerable, SomeClass { string Property { get; } void Method(); } Another added benefit would be IntelliSense. I’ve been getting mixed reactions to this proposal. What do you think? Would this be useful?

  • How to best design a date/geographic proximity query on GAE?

    - by Dane
    Hi all, I'm building a directory for finding athletic tournaments on GAE with web2py and a Flex front end. The user selects a location, a radius, and a maximum date from a set of choices. I have a basic version of this query implemented, but it's inefficient and slow. One way I know I can improve it is by condensing the many individual queries I'm using to assemble the objects into bulk queries. I just learned that was possible. But I'm also thinking about a more extensive redesign that utilizes memcache. The main problem is that I can't query the datastore by location because GAE won't allow multiple numerical comparison statements (<,<=,=,) in one query. I'm already using one for date, and I'd need TWO to check both latitude and longitude, so it's a no go. Currently, my algorithm looks like this: 1.) Query by date and select 2.) Use destination function from geopy's distance module to find the max and min latitude and longitudes for supplied distance 3.) Loop through results and remove all with lat/lng outside max/min 4.) Loop through again and use distance function to check exact distance, because step 2 will include some areas outside the radius. Remove results outside supplied distance (is this 2/3/4 combination inefficent?) 5.) Assemble many-to-many lists and attach to objects (this is where I need to switch to bulk operations) 6.) Return to client Here's my plan for using memcache.. let me know if I'm way out in left field on this as I have no prior experience with memcache or server caching in general. -Keep a list in the cache filled with "geo objects" that represent all my data. These have five properties: latitude, longitude, event_id, event_type (in anticipation of expanding beyond tournaments), and start_date. This list will be sorted by date. -Also keep a dict of pointers in the cache which represent the start and end indices in the cache for all the date ranges my app uses (next week, 2 weeks, month, 3 months, 6 months, year, 2 years). -Have a scheduled task that updates the pointers daily at 12am. -Add new inserts to the cache as well as the datastore; update pointers. Using this design, the algorithm would now look like: 1.) Use pointers to slice off appropriate chunk of list based on supplied date. 2-4.) Same as above algorithm, except with geo objects 5.) Use bulk operation to select full tournaments using remaining geo objects' event_ids 6.) Assemble many-to-manys 7.) Return to client Thoughts on this approach? Many thanks for reading and any advice you can give. -Dane

  • C# .NET MVC Call an action from another controller

    - by Brian
    I have two different objects: contracts, and task orders. My requirements specify that in order to view the Details for either object, the Url should be "http://.../Contract/Details" or "http://.../TaskOrder/Details" depending on which type. They are both very similar and the details pages are almost identical, so I made a class that can either be a contract or a task order, and has a variable "objectTypeID" that says which type it is. I wrote the action "Details" in the task order controller, but now I want to call that from the contract controller instead of recopying the code. So is there any way to have the url still say ".../Contract/Details" but call the action in the TaskOrder controller instead? I tried using TaskOrderController TOController = new TaskOrderController(); TOController.Details(id); This would have worked except that I can't use the HttpContext.Session anymore, which I used several times in the action.

I am getting following error: Type 'Types1:Enums+WindowModeEnum' was not found. at MS.Internal.Metadata.ExposedTypes.ValueSerializers.StaticMemberDocumentValueSerializer.ConvertToDocumentValue(ITypeMetadata type, String value, IServiceProvider documentServices) at MS.Internal.Design.DocumentModel.DocumentTrees.Markup.XamlMarkupExtensionPropertyBase.get_Value() at MS.Internal.Design.DocumentModel.DocumentTrees.DocumentPropertyWrapper.get_Value() at MS.Internal.Design.DocumentModel.DocumentTrees.InMemory.InMemoryDocumentProperty..ctor(DocumentProperty property, InMemoryDocumentItem item) at MS.Internal.Design.DocumentModel.DocumentTrees.InMemory.InMemoryDocumentItem.SetUpItem(DocumentItem item) Same error exist in VS2008, VS2010. Does anybody has any idea, how to deal with it so I can open window in design mode. Thanks a lot. Sincerely, Vlad.

  • WCF : Endpoints clarifications

    - by nettguy
    Except netNamedPipeBinding, we can have multiple endpoints of same transport.Is it correct? example <service name = "TestService"> <endpoint address = "http://localhost:8000/TestService/" binding = "wsHttpBinding" contract = "ITestContract" /> <endpoint address = "net.tcp://localhost:8001/TestService/" binding = "netTcpBinding" contract = "ITestContract" /> <endpoint address = "net.tcp://localhost:8002/TestService/" binding = "netTcpBinding" contract = "IMyOtherTestContract"/> </service>

  • nhibernate/fluenthibernate throws StackOverflowException

    - by Gianluca Colucci
    Hi there! In my project I am using NHibernate/FluentNHibernate, and I am working with two entities, contracts and services. This is my contract type: [Serializable] public partial class TTLCContract { public virtual long? Id { get; set; } // other properties here public virtual Iesi.Collections.Generic.ISet<TTLCService> Services { get; set; } // implementation of Equals // and GetHashCode here } and this is my service type: [Serializable] public partial class TTLCService { public virtual long? Id { get; set; } // other properties here public virtual Activity.Models.TTLCContract Contract { get; set; } // implementation of Equals // and GetHashCode here } Ok, so as you can see, I want my contract object to have many services, and each Service needs to have a reference to the parent Contract. I am using FluentNhibernate. So my mappings file are the following: public TTLCContractMapping() { Table("tab_tlc_contracts"); Id(x => x.Id, "tlc_contract_id"); HasMany(x => x.Services) .Inverse() .Cascade.All() .KeyColumn("tlc_contract_id") .AsSet(); } and public TTLCServiceMapping() { Table("tab_tlc_services"); Id(x => x.Id, "tlc_service_id"); References(x => x.Contract) .Not.Nullable() .Column("tlc_contract_id"); } and here comes my problem: if I retrieve the list of all contracts in the db, it works. if I retrieve the list of all services in a given contract, I get a StackOverflowException.... Do you see anything wrong with what I wrote? Have I made any mistake? Please let me know if you need any additional information. Oh yes, I missed to say... looking at the stacktrace I see the system is loading all the services and then it is loading again the contracts related to those services. I don't really have the necessary experience nor ideas anymore to understand what's going on.. so any help would be really really great! Thanks in advance, Cheers, Gianluca.

  • database schema eligible for delta synchronization

    - by WilliamLou
    it's a question for discussion only. Right now, I need to re-design a mysql database table. Basically, this table contains all the contract records I synchronized from another database. The contract record can be modified, deleted or users can add new contract records via GUI interface. At this stage, the table structure is exactly the same as the Contract info (column: serial number, expiry date etc.). In that case, I can only synchronize the whole table (delete all old records, replace with new ones). If I want to delta(only synchronize with modified, new, deleted records) synchronize the table, how should I change the database schema? here is the method I come up with, but I need your suggestions because I think it's a common scenario in database applications. 1)introduce a sequence number concept/column: for each sequence, mark the new added records, modified records, deleted records with this sequence number. By recording the last synchronized sequence number, only pass those records with higher sequence number; 2) because deleted contracts can be added back, and the original table has primary key constraints, should I create another table for those deleted records? or add a flag column to indicate if this contract has been deleted? I hope I explain my question clearly. Anyway, if you know any articles or your own suggestions about this, please let me know. Thanks!

  • Why won't jqGrid populate initially in Chrome

    - by Maxm007
    Hi, I've got a web page with a jqGrid that uses am xmlreader to populate itself with data that is spat out by a RoR service. The page loads fine in firefox and safari.

  • Could not find default endpoint element

    - by edosoft
    I've added a proxy to a webservice to a VS2008/.NET 3.5 solution. When constructing the client .NET throws this error: Could not find default endpoint element that references contract 'IMySOAPWebService' in the service model client configuaration section. This might be because no configuaration file was found for your application or because no end point element matching this contract could be found in the client element Searching for this error tells me to use the full namespace in the contract. Here's my app.config with full namespace: <client> <endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService" binding="basicHttpBinding" bindingConfiguration="IMySOAPWebServicebinding" contract="Fusion.DataExchange.Workflows.IMySOAPWebService" name="IMySOAPWebServicePort" /> </client> I'm running XP local (I mention this because a number of Google hits mention win2k3) The app.config is copied to app.exe.config, so that is also not the problem. Any clues?

  • How to get unique values when using a UNION mysql query

    - by Roland
    I have 2 sql queries that return results, both contain a contract number, now I want to get the unique values of contract numbers HEre's the query (SELECT contractno, dsignoff FROM campaigns WHERE clientid = 20010490 AND contractno != '' GROUP BY contractno,dsignoff) UNION (SELECT id AS contractno,signoffdate AS dsignoff FROM contract_details WHERE clientid = 20010490) So for example, if the first query before the union returns two results with contract no 10, and the sql query after the union also returns 10, then we have 3 rows in total, however because contractno of all three rows is 10, I need to have only one row returned, Is this possible?
