  • Strong Signing, and Updating A Referencing Assembly

    - by Alan
    Hi, I have two, third party assemblies: Foo.dll and ReferencesFoo.dll As noted, ReferencesFoo.dll is an assembly that has a reference to Foo.dll For my application, I need to resign these assemblies. I use ildasm/ilasm in combination along with a signing key to resign them, however, ReferencesFoo.dll still contains (in it's manifest?) the reference to the Foo.dll old public key and public key token. So, how do I sign both dll's with my key, and update the references in ReferencesFoo.dll without getting the source code and recompiling?

  • Calling Class from another File ASP.NET VB.NET

    - by davemackey
    Lets say I have a class like this in class1.vb: Public Class my_class Public Sub my_sub() Dim myvar as String myvar = 10 Session("myvar") = myvar End Sub End Class Then I have a ASP.NET page with a code-behind file, default.aspx and default.aspx.vb and I want to call my_class. I'm doing the following, but it doesn't work: Imports my_app.my_class Partial Public Class _default Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender as Object, ByVal e as System.EventArgs) Handles Me.Load my_class() End Sub End Class I get a "Reference to a non-shared member requires an object reference"

  • How to transform a vector<int> into a string?

    - by Legend
    I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

  • GAE Datastore: persisting referenced objects

    - by David
    Two "I'm sorries" to begin with: 1) I've looked for a solution (here, and elsewhere), and couldn't find the answer. 2) English is not my mother tongue, so I may have some typos and the sort - please ignore them. To the point: I am trying to persist Java objects to the GAE datastore. I am not sure as to how to persist object having ("non-trivial") referenced object. That is, assume I have the following. public class Father { String name; int age; Vector<Child> offsprings; //this is what I call "non-trivial" reference //ctor, getters, setters... } public class Child { String name; int age; Father father; //this is what I call "non-trivial" reference //ctor, getters, setters... } The name field is unique in each type domain, and is considered a Primary-Key. In order to persist the "trivial" (String, int) fields, all I need is to add the correct annotation. So far so good. However, I don't understand how should I persist the home-brewed (Child, Father) types referenced. Should I: Convert each such reference to hold the Primary-Key (a name String, in this example) instead of the "actual" object. So, Vector<Child> offsprings; becomes Vector<String> offspringsNames; ? If that is the case, how do I handle the object at run-time? Do I just query for the Primary-Key from Class.getName, to retrieve the refrenced objects? Convert each such reference to hold the actual Key provided to me by the Datastore upon the proper put() operation? So, Vector<Child> offsprings; becomes Vector<Key> offspringsHashKeys; ? I would very much appreciate all kinds of comments. I have read ALL the offical relevant GAE docs/example. Throughout, they always persist "trivial" references, natively supported by the Datastore (e.g. in the Guestbook example, only Strings, and Longs). Many thanks, David

  • Matlab: Adding symbols to figure

    - by niko
    Hi, Below is the user interface I have created to simulate LDPC coding and decoding The code sequence is decoded iteratively by passing values between the left and right nodes through the connections. The first thing it would be good to add in order to improve visualization is to add arrows to the connections in the direction of passing values. The alternative is to draw a bigger arrow at the top of the connection showing the direction. Another thing I would like to do is displaying the current mathematical operation below the connection (in this example c * H'). What I don't know how to do is displaying special characters and mathematical symbols and other kinds of text such as subscript and superscript in the figure (for example sum sign and subscript "T" instead of sign ="'" to indicate transposed matrix). I would be very thankful if anyone could point to any useful resources for the questions above or show the solution. Thank you.

  • Sending POST variables through a PHP proxy for AJAX?

    - by b. e. hollenbeck
    I've decided that using a PHP proxy for AJAX calls for a project is the best way to go - but I have a question regarding passing POST data through the proxy. As in - how to do it. Should I need to create a single variable in the javascript using alternate characters, then have the PHP proxy parse and modify the variable to reassemble a valid HTTP request? Or is there some means of passing along the $_POST array in new request to the external server by pulling the data out of the headers and re-sending it?

  • Version control: delete branches after merging?

    - by Nathan Long
    When you branch some code, finish working with the branch, and merge it back to the trunk, what do you do with the branch? Delete it from the repository? Keep it for reference? It seems like you would keep it for reference, but I imagine the /branches directory could get pretty cluttered. (If this isn't something people generally agree on, please comment and I'll make it a community wiki.)

  • Javascript objects: get parent

    - by Dänu
    Hey Guys I got some question about nested javascript objects (is it me, google or is javascript quite poorly documented?). Now, I got the following (nested) object: obj: { subObj: { 'hello world' } }; next thing I do is to reference the subobject like this: var s = obj.subObj; now what I would like to do, is to get a reference to the object obj out of the variable s. Something like: var o = s.parent; Is this somehow possible?

  • Delphi memory management design strategies : Object or Interface ?

    - by Pierre-Jean Coudert
    Regarding Delphi memory management, what are your design strategies ? What are the use cases where you prefer to create and release Objects manually ? What are the uses cases where Interfaces, InterfacedObjects, and their reference counting mechanism will be prefered ? Do you have identified some traps or difficulties with reference counted objects ? Thanks for sharing your experience here.

  • MVC actionlink posting List of complex type

    - by Ying
    I have an actionlink that on click im passing a List of objects to a controller action. Example: View: Html.ActionLink("TestLink", "TestMethod", "Test", Model.SampleList, null) TestController: public ActionResult TestMethod(List sampleList) { return View(sampleList); } When I do this I get a null sampleList. I can pass a single complex object fine just not a collection of it. Do I need the correct routing for this? The reason I'm doing this is instead of passing an id and do a look up in the controller action, I just pass in the data.

  • How to access static members in a Velocity template?

    - by matt b
    I'm not sure if there is a way to do this in Velocity or not: I have a User POJO which a property named Status, which looks like an enum (but it is not, since I am stuck on Java 1.4), the definition looks something like this: public class User { // default status to User private Status status = Status.USER; public void setStatus(Status status) { this.status = status; } public Status getStatus() { return status; } And Status is a static inner class: public static final class Status { private String statusString; private Status(String statusString) { this.statusString = statusString; } public final static Status USER = new Status("user"); public final static Status ADMIN = new Status("admin"); public final static Status STATUS_X = new Status("blah"); //.equals() and .hashCode() implemented as well } With this pattern, a user status can easily be tested in a conditional such as if(User.Status.ADMIN.equals(user.getStatus())) ... ... without having to reference any constants for the status ID, any magic numbers, etc. However, I can't figure out how to test these conditionals in my Velocity template with VTL. I'd like to just print a simple string based upon the user's status, such as: Welcome <b>${user.name}</b>! <br/> <br/> #if($user.status == com.company.blah.User.Status.USER) You are a regular user #elseif($user.status == com.company.blah.User.Status.ADMIN) You are an administrator #etc... #end But this throws an Exception that looks like org.apache.velocity.exception.ParseErrorException: Encountered "User" at webpages/include/dashboard.inc[line 10, column 21] Was expecting one of: "[" ... From the VTL User Guide, there is no mention of accessing a Java class/static member directly in VTL, it appears that the right hand side (RHS) of a conditional can only be a number literal, string literal, property reference, or method reference. So is there any way that I can access static Java properties/references in a Velocity template? I'm aware that as a workaround, I could embed the status ID or some other identifier as a reference in my controller (this is a web MVC application using Velocity as the View technology), but I strongly do not want to embed any magic numbers or constants in the view layer.

  • Is there an implementation of rapid concurrent syntactical sugar in scala? eg. map-reduce

    - by TiansHUo
    Passing messages around with actors is great. But I would like to have even easier code. Examples (Pseudo-code) val splicedList:List[List[Int]]=biglist.partition(100) val sum:Int=ActorPool.numberOfActors(5).getAllResults(splicedList,foldLeft(_+_)) where spliceIntoParts turns one big list into 100 small lists the numberofactors part, creates a pool which uses 5 actors and receives new jobs after a job is finished and getallresults uses a method on a list. all this done with messages passing in the background. where maybe getFirstResult, calculates the first result, and stops all other threads (like cracking a password)

  • Refreshing Visual Studio's COM references tab

    - by r_honey
    I right-clicked on the bin folder of my web app to add a COM Reference. I did not find the desired Com reference in the list. I went back to the Command Line to register by desired Com dll using resvr32. However, the COM references tab does not shows it (looks like the information is cached somewhere). Even restarting VS did not help. Is their any easy way to refresh the COM references tab without rebooting the machine itself??

  • Zend Framework Router Getting /module/VALUE/controller/action

    - by cappuccino
    I've been googling around and I can't seem to find anything which explains the use of ZF router well. I've read the documentation on the site, which seems to only talk about re-routing. I am trying to make the format: /module/value/controller/action give /module/controller/action passing on value as a parameter e.g. /store/johnsmithbigsale/home/newstuff would route to /store/home/newstuff passing on johnsmithbigsale as the value to a parameter with a hidden namespace e.g. storeName. Some help would be greatful!

  • Oracle: Use of notational parameters which calling functions in insert statements not allowed ?

    - by Sathya
    Why does Oracle 10 R2 not allow use of notational parameters while calling functions in insert statements ? In my app, I'm calling a function in an insert statement. If use notational method of parameter passing, I get an ORA-00907: Missing right parenthesis error message INSERT INTO foo (a, b, c) VALUES (c, F1(P1=>'1', P2=>'2', P3 => '3'), e) Changing the same to position based parameter passing, and the same code gets compiled with no errors. INSERT INTO foo (a, b, c) VALUES (c, F1('1','2','3'), e) Why is this so ?
