• Cisco 2950 Express Setup

  - by adamtor45

  I've been donated a Cisco Catalyst 2950 Switch by the company I work for to have a play with. I've reset it back to Factory Defaults, but having an issue with getting to Express Setup. I've followed the Express Setup (And Factory Reset) guide as listed here: Catalyst 2950 Switch Getting Started Guide Everything goes fine, until I get to step 10, I enter 10.0.0.1 into the browser, but I just get a Error 324 response. ServerFault wouldn't let me post a picture, so here is a link to the browser screenshot: Does anyone have any suggestions as to what this may be? Thanks in advance!

• child objects in rdlc (Studio 2010RC)

  - by Jim

  Hi, I am attempting to reference a sub-object in a field expression in a studio 2010 report. This used to work in prior versions. When account references another object with properties the following used to work. =Fields!Account.Value.Name (Name is a property of the child object, Account is the parent object) The same expression syntax no longer works. How do I reference the properties of a sub-object in reporting services in an rdlc in studio 2010. Thanks

• mysql circular dependency in foreign key constraints

  - by Flavius

  Given the schema: What I need is having every user_identities.belongs_to reference an users.id. At the same time, every users has a primary_identity as shown in the picture. However when I try to add this reference with ON DELETE NO ACTION ON UPDATE NO ACTION, MySQL says #1452 - Cannot add or update a child row: a foreign key constraint fails (yap.#sql-a3b_1bf, CONSTRAINT #sql-a3b_1bf_ibfk_1 FOREIGN KEY (belongs_to) REFERENCES users (id) ON DELETE NO ACTION ON UPDATE NO ACTION) I suspect this is due to the circular dependency, but how could I solve it (and maintain referential integrity)?

• Problem migrating membershipProvider functionality from mvc1 to mvc2

  - by Jericho

  I am migrating a web app in mvc1 to mvc2. When it came down to migrating my MembershipProvider authentication I keep getting errors that MembershipProvider and MembershipCreateStatus type cannot be found. I do have the reference to System.Web which to my understanding includes the Security reference, but when I examine the the object, those types do not appear. I am just getting familiar with mvc2, if anyone has any input on this it would be extremely appreciated.

• Javascript (JSON) 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?

  - by Rooneyl

  I am looking into setting up a remote git repo. To start with I have created it on my Windows machine using xampp following this guide. All works fine except when I try to add some security, as per step 6 of the guide (for when I migrate it to my main web server).

This works fine (I have checked in my web browser), but when I try and push I get prompted for my password the it fails with a error (code 22). $ git push origin master Password for 'http://git@localhost': error: Cannot access URL http://git@localhost/s.git/, return code 22 fatal: git-http-push failed Any ideas?

EDIT: If this is not possible, should I consider cURL as an option?

• Does the compiler optimize the function parameters passed by value?

  - by Naveen

  Lets say I have a function where the parameter is passed by value instead of const-reference. Further, lets assume that only the value is used inside the function i.e. the function doesn't try to modify it. In that case will the compiler will be able to figure out that it can pass the value by const-reference (for performance reasons) and generate the code accordingly? Is there any compiler which does that?

• Rvalues in C++03

  - by DeadMG

  How can you tell whether or not a given parameter is an rvalue in C++03? I'm writing some very generic code and am in need of taking a reference if possible, or constructing a new object otherwise. Can I overload to take by-value as well as by-reference and have the rvalue returns call the by-value function? Or do I have a very sickening feeling that this is why rvalue references are in C++0x?

• Excel macro to change location of .cub files used by pivot tables? (to allow .xls files that depend

  - by Rory

  I often use Excel with pivot tables based on .cub files for OLAP-type analysis. This is great except when you want to move the xls and you realise internally it's got a non-relative reference to the location of the .cub file. How can we cope with this - ie make it convenient to move around xls files that depend on .cub files? The best answer I could come up with is writing a macro that updates the pivot tables' reference to the .cub file location....so I'll pop that in an answer.

• How to serialize a Linq to Sql object graph without hiding the child's "Parent" member

  - by Richard B

  Without hiding the Child object's reference to the Parent object, has anyone been able to use an XmlSerializer() object to move a Linq to SQL object to an XML document, or is the only appropriate way of handling this to create a custom serialization/deserialization class to handle moving the data to/from the xml document? I don't like the idea of hiding the child object's reference to the parent object is why I'm asking. Thx.

• Is there a way to look up the Publishers URL using the linkshare.com API

  - by steve

  I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building. I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?

• Are there any C++ style and/or standard example files available?

  - by Harvey

  While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?
