  • How Can I Reference Multiple Primary Keys For A Vector Type Primary Key

    - by AndreiC
    Hi, I have the following scenario: a table of projects and a table of persons, working on one or serveral projects. Also, I have a project id column (of type int), in the first table, which is a primary key there and I have a vector of project ids, as a column of type int, in my second table (persons), that references primary keys from the first table. What is the correct syntax for referencing multiple primary keys, from a vector foreign key. This is the way I am trying to create the table, but I am not sure what to place at the indicated line: CREATE TABLE Persons( Person_Id int, ..., ProjectsList int[], FOREIGN KEY (ProjectsList) REFERENCES Projects(Project_id) -- not sure what how to define the link here ); I hope my explanations are not over-complicated. Thank you in advance for helping!

  • Type problem when including tuple

    - by Person
    I'm using Visual Studio 2008 with Feature Pack 1. I have a typedef like this typedef std::tr1::tuple<std::string, std::string, int> tileInfo with a function like this const tileInfo& GetTile( int x, int y ) const. In the implementation file the function has the exact same signature (with the added class name qualifier) and I am getting a redefinition: different type modifiers error. It seems to be looking for an int& instead of a tileInfo& When I mouse over the type of the function in the header, i.e. tileInfo& it brings up a little bar saying static const int tileInfo. I think this may be the problem, but I'm not sure what to do. Any help is appreciated, thanks.

  • Select a data template by item type programatically in WPF

    - by Michael Stoll
    Hi all, unfortunately the WPF ToolbarTray does not support binding to a collection of ToolbarViewModels (Correct me, if I'm wrong). Thus I want to create the Toolbars programmatically. So there are two tasks, which I don't know how to do: Select the data template based on the item type. Instantiate the data template as toolbar Both should do the same as WPF does, when we use ItemsControl with an enumerable content and empty template. I used reflector to anaylse what WPF does. Task 1 is done by FrameworkElement.FindTemplateResourceInternal, but this is internal, and I couldn't find any public methods to acomplish the task. Of course one could enumerate all resources and match the data template data type property, but this seems sub-optimal. Who know's how to acomplish these tasks?

  • How to invoke a method with a generic return type using reflection

    - by Andre Luus
    Hi there! I'm trying to invoke a method with reflection that has a generic return type, like this: public class SomeClass<T> { public List<T> GetStuff(); } I get an instance of SomeClass with a call to a Repository's GetClass<T> generic method. MethodInfo lGetSomeClassMethodInfo = typeof(IRepository) .GetMethod("GetClass") .MakeGenericMethod(typeof(SomeClass<>); object lSomeClassInstance = lGetSomeClassMethodInfo.Invoke( lRepositoryInstance, null); After that, I this is where I try to invoke the GetStuff method: typeof(SomeClass<>).GetMethod("GetStuff").Invoke(lSomeClassInstance, null) I get an exception about the fact that the method has generic arguments. However, I can't use MakeGenericMethod to resolve the return type. Also, if instead of typeof(SomeClass<>) I use lSomeClassInstance.GetType() (which should have resolved types) GetMethod("GetStuff") returns null! UPDATE I have found the solution and will post the answer shortly.

  • Confirm that two filesystems are identical, ignoring special files

    - by endolith
    /media/A and /media/B should be identical, but I want to confirm before deleting one. Duplicate file finders don't work, because they'll find two copies of the same file within B, for instance. I only want to confirm that every file in one is identical to the other. diff -qr /media/A/ /media/B/ seems to work, but the output is cluttered with garbage like diff: /media/A//etc/alternatives/ControlPanel: No such file or directory and File /media/A//dev/tty8 is a character special file while file /media/B//dev/tty8 is a character special file I can suppress the former with 2> /dev/null, but I don't know about the latter. rsync -avn /media/A/ /media/B/ also produces a bunch of clutter, like "skipping non-regular file". How can I compare the two trees and just make sure that all the real files exist in both and are identical?

  • Changing an Action Type="click" to an auto action in SVG

    - by Dustin Myers
    I have a SVG document that I exported from Visio 2003 that would like to edit. This file has an action where you click a button it will navigate to a new screen. What I would like to do is have the navigation be based off of a data point rather than having to click the button. As an example I have a dynamic point data being brought into the SVG file and when that value changes from 0 to 1, I want this screen to automatically navigate to another screen. Below is the code I for clicking the button. <title content="structured text">Sheet.1107</title> <desc content="structured text">Button 1</desc> <v:custProps> <v:cp v:ask="false" v:langID="1033" v:invis="false" v:cal="0" v:val="VT4(Test Graphic 2)" v:type="0" v:prompt="" v:nameU="ObjRef" v:sortKey="" v:lbl="" v:format=""/> <v:cp v:ask="false" v:langID="1033" v:invis="false" v:cal="0" v:val="VT4(SF-S)" v:type="0" v:prompt="" v:nameU="DataPt" v:sortKey="" v:lbl="" v:format=""/> </v:custProps> <v:userDefs> <v:ud v:prompt="" v:nameU="NAVIGATE" v:val="VT4(NAVIGATE Test Graphic 2,&apos;&apos;,)"/> </v:userDefs> <v:textBlock v:margins="rect(4,4,4,4)"/> <v:textRect width="125.01" height="35" cx="62.5" cy="517.5"/> <rect x="0" width="125" y="500" height="35" class="st3"/> <text x="40.15" y="521.1" v:langID="1033" class="st4"><v:paragraph v:horizAlign="1"/><v:tabList/>Button 1</text> <jci:action type="click" count="1">if(evt.button == 0) nav(&apos;Test Graphic 2&apos;,&apos;&apos;,&apos;&apos;);</jci:action></g></a> In the above code I am bringing in the data value from SF-S. Once that value is equal to 1 I want this screen to automatically navigate to Test Graphic 2. I don't have any experience with coding so I am hoping someone here will be able to help me. Thanks, DMyers

  • Replace input type=file by an image

    - by nikospkrk
    Hi, Like a lot of people, I'd like to customize the ugly input type=file, and I know that it can't be done without some hacks and/or javascript. But, the thing is that in my case the upload file buttons are just for uploading images (jpeg|jpg|png|gif), so I was wondering if I could use a "clickable" image which would act exactly as an input type file (show the dialog box, and same $_FILE on submitted page). I found some workaround here, and this interesting one too (but does not work on Chrome =/). What do you guys do when you want to add some style to your file buttons? If you have any point of view about it, just hit the answer button ;) Cheers, Nicolas

    - by Andy Clarke
    Hi, I'm reflecting a property 'Blah' its Type is ICollection public ICollection<string> Blah { get; set; } private void button1_Click(object sender, RoutedEventArgs e) { var pi = GetType().GetProperty("Blah"); MessageBox.Show(pi.PropertyType.ToString()); } This gives me (as you'd expect!) ICollection<string> ... But really I want to get the collection type i.e. ICollection (rather than ICollection<string>) - does anyone know how i'd do this please?

  • Is it possible to set ContentType for a WCF WebGet method?

    - by James Cadd
    I'm working with a WCF restful/http method that returns a stream of image data. I want to make sure that the content type is marked as "image/png". The method is defined as: [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class TileImageService { [WebGet(UriTemplate = "{id}")] public Stream GetTileImage(string id) { Bitmap bmp = new Bitmap(173, 173); Graphics g = Graphics.FromImage(bmp); g.Clear(Color.Blue); g.DrawString(DateTime.Now.ToLongTimeString(), new Font("Chiller", 20), Brushes.White, new PointF(10, 10)); g.Flush(); MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Png); ms.Seek(0, SeekOrigin.Begin); return ms; } } In Firefox it looks like the content type is marked as application/octet stream. Is there a way to change the content type?

  • Visual Studio - easy way to bring up type definition as source code

    - by Igor Zevaka
    Oftentimes I want to bring up a system class in a source view, so that I can browse the properties and methods exposed by the class in a source view. Below is the screenshot of what I mean: Usually I do this by selecting the class name and pressing F12 (or right clickGo To Definition). However, if I haven't got it anywhere ready, i have type it up and then do Go To Definition. Most of the time I have to delete what I typed later on. Is there a way to bring up this view without having to type the class name? The VS2010 Navigate To dialog doesn't support this.

  • Constructor type not found

    - by WaffleTop
    Hello, What I am doing: I am taking the Microsoft Enterprise Library 4.1 and attempting to expand upon it using a few derived classes. I have created a MyLogEntry, MyFormatter, and MyTraceListener which derive from their respective base classes when you remove the "My" from their names. What my problem is: Everything compiles fine. When I go to run a test using Logger.Write(logEntry) it errors right after it initializes MyTraceListener with an error message: "The current build operation (... EnterpriseLibrary.Logging.LogWriter, null]) failed: Constructor on type 'MyLogging.MyFormatter' not found. (Strategy type ConfiguredObjectStrategy, index 2) I figured it was something to do with the constructor so I tried removing it, add it, and adding a call to the base class LogFormatter. Nothing has worked. Does anyone have insight into this problem? Is it maybe a reference issue? Bad App.config configuration? Thank you in advance

  • Unknown attribute xsi:type in XmlSerializer

    - by vanccoon
    I am learning XML Serialization and meet an issue, I have two claess [System.Xml.Serialization.XmlInclude(typeof(SubClass))] public class BaseClass { } public class SubClass : BaseClass { } I am trying to serialize a SubClass object into XML file, I use blow code XmlSerializer xs = new XmlSerializer(typeof(Base)); xs.Serialize(fs, SubClassObject); I noticed Serialization succeed, but the XML file is kind of like ... If I use XmlSerializer xs = new XmlSerializer(typeof(Base)); SubClassObject = xs.Deserialize(fs) as SubClass; I noticed it will complain xsi:type is unknown attribute(I registered an event), although all information embedded in the XML was parsed successfully and members in SubClassObject was restored correctly. Anyone has any idea why there is error in parsing xsi:type and anything I did wrong? Thanks

  • saving a records containing a member of type string to a file (Delphi, Windows)

    - by wonderer
    I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

  • VB.NET template instance - passing a variable data type

    - by FerretallicA
    As the title suggests, I'm tyring to pass a variable data type to a template class. Something like this: frmExample = New LookupForm(Of Models.MyClass) 'Works fine Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine repoGeneric = New Repositories.Repository(Of SelectedType) 'Ba-bow! repoGeneric = New Repositories.Repository(Of InstanceOfMyClass.GetType()) 'Ba-bow! I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either. (How) can I create an instance of a dynamically typed repository at runtime?

  • How to change a variable type in C#?

    - by Mosho Mulan
    I wanted to use something like this: if(x==5) { var mydb= ........ ; } else { var mydb = ........ ; } but it didn't work because I can't declare a variable inside if statement. So I tried to do this: var mydb; if (x==5) { mydb= ............. ; } else { mydb=.............; } but id didn't work either because I had to initialize the variable (mydb). So the question is: I don't necessarily know the type of the variable, can I declare it anyway and then change the type inside the if statement?

  • How to know file type without extension

    - by Ayusman
    While trying to come-up with a servlet based application to read files and manipulate them (image type conversion) here is a question that came up to me: Is it possible to inspect a file content and know the filetype? Is there a standard that specifies that each file MUST provide some type of marker in their content so that the application will not have to rely on the file extension constraints? Consider an application scenario: I am creating an application that will be able to convert different file formats to a set of output formats. Say user uploads an PDF, my application can suggest that the possible conversion formats are microsoft word or TIFF or JPEG etc. As my application will gradually support different file formats (over a period of time), I want my application to inspect the input file instead of having the user to specify the format. And suggest to user the possible formats of output. I understand this is an open ended, broad question. Please let me know if it needs to be modified. Thanks, Ayusman

  • Mercurial merge strategy per file type

    - by dls
    All: I want to use kdiff to merge all files with a certain suffix (say *.c, *.h) and I want to do two things (turn off premerge and use internal:other) for all files with another suffix (say *.mdl). The purpose of this is to allow me to employ a type of 'clobber merge' for a specific file type (ie: un-mergable files like configurations, auto-generated C, models, etc..) In my .hgrc I've tried: [merge-tools] kdiff3= clobbermerge=internal:other clobbermerge.premerge = False [merge-patterns] **.c = kdiff3 **.h = kdiff3 **.mdl = clobbermerge but it still triggers kdiff3 for all files. Thoughts? An extension of this would be to perform a 'clobber merge' on a directory - but once the syntax is clear for a file suffix, the dir should be easy.

  • Core Data data type for just the date - not including time

    - by Jason
    I am new at Core Data, and it seems like it is a great way to manage the data store. However I am also very memory-conscious due to the fact that the iPhone doesn't have that much of it. I was a little surprised to see that the data types are so limited - eg. there is a Date type which includes also the time, but no Date type for just the date! All the time information takes up precious bytes of memory, if I just wanted an attribute with the date (e.g. 2/15/2010 rather than 2/15/2010 02:34:48), how could I do this? Is it possible?

  • Best approach to limit users to a single node of a given content type in Drupal

    - by Chaulky
    I need to limit users to a single node of a given content type. So a user can only create one node of TypeX. I've come up with two approaches. Which would be better to use... 1) Edit the node/add/typex menu item to check the database to see if the user has already created a node of TypeX, as well as if they have permissions to create it. 2) When a user creates a node of TypeX, assign them to a different role that doesn't have permissions to create that type of node. In approach 1, I have to make an additional database call on every page load to see if they should be able to see the "Create TypeX" (node/add/typex). But in approach 2, I have to maintain two separate roles. Which approach would you use?

  • determine which value produced a hit in SOLR multivalued field type

    - by harschware
    If I have a multiValued field type of text, and I put values [cat,dog,green,blue] in it. Is there a way to tell when I execute a query against that field for dog, that it was in the 1st element position for that multiValued field? Assumption: client does not have any pre-knowledge of what the field type of the field being queried is. (i.e. Solr must provide the answer and the client can't post process the return doc to figure it out because it would not know how SOLR matched the query to the result). Disclosure: I posted to solr-user list and am getting no traction so I post here now.
