• TCP 3 way handshake

  - by Tom

  Hi, i'm just observing what NMAP is doing for the 3 ports it reports are open. I understand what a half-scan attack is, but what's happening doesnt make sense. NMAP is reporting ports 139 are 445 are open..... all fine. But when i look at the control bits, NMAP never sends RST once it has found out the port is open, It does this for port 135- but not 139 and 445. This is what happens: (I HAVE OMITTED THE victim's replies) Sends a 2 (SYN) Sends a 16 (ACK) Sends a 24 (ACK + PST) Sends a 16 (ACK) Sends a 17 (ACK + FIN) I dont get why NMAP doesnt 'RST' ports 139 and 445??

• Facebook Like button - comment box with breif description and image

  - by Dave Smith

  On my website when the user selects the facebook like button they have the option to enter comments. This popup window to enter comments only contains the users avatar and place to enter comments. How can i include my pic and a brief description of the site directly below the comment??? At first I thought it was from the HTML title attribute or meta property="og:title" ... but populating these have no affect I have another site that contains both pic and a desc below the comment but the pic seems to be grabed at random -but always the same- from the site and the short desc I thought from the -title- attribute but its not - I changed the -title- and it still shows the same desc, its like its cached??? Any ideas how to control or populate a brief description and image within the comment section of a like button???

• LinkButton child controls render

  - by Alex

  Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

• Gridview with row being edited causing error when form submitted

  - by Chris Phelps

  Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated - "Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. " Any idea how to prevent this error??

• Best Tools for Software Maintenance Engineering

  - by Pev

  Yes, the dreaded 'M' word. You've got a workstation, source control and half a million lines of source code that you didn't write. The documentation was out of date the moment that it was approved and published. The original developers are LTAO, at the next project/startup/loony bin and not answering email. What are you going to do? {favourite editor} and Grep will get you started on your spelunking through the gnarling guts of the code base but what other tools should be in the maintenance engineers toolbox? To start the ball-rolling; I don't think I could live without source-insight for C/C++ spelunking. (DISCLAIMER: I don't work for 'em).

• Do you allow check-ins associated with work items from another Team Project?

  - by muerte

  Team Foundation Server 2008 allows that every check-in is associated with a work item, but what do you do if you are developing some features which span several Team Projects? For example, you're developing a specific product for a client and that product has its own Team Project, but is also using some of your other components or tools which are maintained independently in another Team Project. Where do you create work items for requirements which involve a change in both projects? Separated, every work item in its own Team Projects All work items in clients Team Project, regardless of associated source code The latter seems easier to maintain and control, but it involves associating check-ins from one Team Project to work items in another.

• The cost of finalize in .Net

  - by Jules

  (1) I've read a lot of questions about IDisposable where the answers recommend not using Finalize unless you really need to because of the process time involved. What I haven't seen is how much this cost is and how often it's paid. Every millisecond? second? hour, day etc. (2) Also, it seems to me that Finalize is handy when its not always known if an object can be disposed. For instance, the framework font class. A control can't dispose of it because it doesn't know if the font is shared. The font is usually created at design time so the user won't know to dispose it, therefore finalize kicks in to finally get rid of it when there are no references left. Is that a correct impression?

• Execute a dll function in ASP.Net Bin not working, II7.

  - by Wayne Lo

  I am developing a remote control application where a client (aspx page in a browser) can request a server to "launch a notepad" (for testing purpose, for real life, turning off a light bulb, etc). So I created a dll with a simple function for launching the notepad (on the server side) and dropped this dll in the root bin folder. It worked fine when the aspx page is running under ASP.NET development server (launched from Visual Studio). But when I tested the same aspx page under a FireFox browser, it did not work (launch the notepad) even though it did call for the same function (I stepped through in debugger). Is this a permission issue? How do I set this up in IIS manager, or even better in web.config? Please help.

• Can anyone recommend a .Net XML Serialization library?

  - by James

  Can anyone recommend a .Net XML Serialization library (ideally open source). I am looking for a robust XML serialization library that I can throw any object at, which will produce a human readable XML representation of the public properties for logging purposes. I never need to be able to deserialize. XmlSerializer's requirement of an object having a parameter constructor is too restrictive for what I want. DataContractSerializer does not give enough control over the output (which is not particularly human-readable). Any recommendations appreciated! Thanks

• folder structure for project documentation

  - by Qiulang

  Hi all, I saw some questions raised about the folder structure of source codes, but I never see the question about folder structure of project documentation. I googled it and still do not see many articles talk about. Here is one http://www.projectperfect.com.au/downloads/Info/info_project_folder_structure.pdf To quote some of its words: "There are two broad approaches: Organize by phase so that each top directory is a phase. For example, you might have directories for Feasibility, Business Analysis, Design etc. or whatever your phases are called. Organize by function so that the top directory level are functions. For example, Risks, Requirements, Scope, Change Control, Development. Most times a mix of both are used..." So any thought about it? I believe this is also an important issue!

• FOSUserBundle: embedding the login form and choosing its template

  - by tirengarfio

  i want to insert the login form of FOSUserBundle in my template like this: <div id="sidebar"> {% render "FOSUserBundle::Security::login" %} </div> but not to render the template that is been calling in the code of loginAction() originally. I have thought I'd find useful the possibility of passing the template I want to render as a parameter as 'max' in this example: <div id="sidebar"> {% render "AcmeArticleBundle:Article:recentArticles" with {'max': 3} %} </div> Is that possible in symfony2? If not.. should I create another action for my bundle with the same code inside of loginAction? or should I modify the original loginAction code and write control structures? if(currentPage == 'home') renderResponse('template1') else renderResponse('template2')

• Using jQuery, how to modify text outside of tags?

  - by Jacob

  Given a string of text that is both adjacent to a span and inside of a div, what are some methods to modify just that text, leaving the surrounding HTML intact? For example: <div id="my-div">modify this text<span id="my-span"></span></div> I have tried things like $('#my-div').html(function(i, elem){blah;}); but this seems to cause the span to be deleted and a new span to be added, because some styling is lost. I realize that it would be best to wrap the text string in its own HTML tags before applying client-side code, but that is out of my control.

• Architecture of a secure application that encrypts data in the database.

  - by Przemyslaw Rózycki

  I need to design an application that protects some data in a database against root attack. It means, that even if the aggressor takes control over the machine where data is stored or machine with the application server, he can't read some business critical data from the database. This is a customer's requirement. I'm going to encrypt data with some assymetric algorithm and I need some good ideas, where to store private keys, so that data is secure as well as the application usability was quite comfortable? We can assume, for simplicity, that only one key pair is used.

• How do I add a new ItemTemplate to a Guidance Automation Toolkit vs2010 .vsix package?

  - by Maslow

  I have a vs2008 GAT package that has been updated to work on vs2010 which walks a developer through creating a custom solution complete with a Service layer project, Domain, usercontrol, and unit test project. I'd like to add a new ItemTemplate to the package to create a user control or dialog that adheres to our current practices. So far it seems I need a Recipe, but I can not find any reference for the GuidancePackage.xml file and how to properly add things to it, let alone how to add a new Item Template or guidance steps and decisions. How can I add an item template to my add-in?

• Icons in Silverlight: Images vs. Vectors

  - by Shnitzel

  I like using the vector drawing feature of Expression Blend to create icons. That way I can change colors easily on my icons without having to resort to an image editor. But my question is... Say I have a treeview control that has an icon next to each tree element and say I have hundreds of elements. Do you think using images is faster - performance wise than using vector icons? B/c I'd rather use vectors but I'm wondering about performance concerns.

• Is it really wrong to version documents using CouchDB's behaviour?

  - by Tomas Sedovic

  This is one of those "I know I shouldn't do this but it's oh so convenient." questions. Sorry about that. I plan to use CouchDB for storing a bunch of documents and keeping their entire revision history. CouchDB does the versioning automatically, but it is strongly discouraged for programmer's use: "You cannot rely on document revisions for any other purpose than concurrency control." From what I've found on the CouchDB wiki, the versions can get deleted either during compaction or during replication. As far as I can tell, Compaction must always be triggered manually and Replication occurs only when there's more than one database server. The question is: if I won't run compaction and will use only single database instance for my documents, can I just use CouchDB's document versioning and expect it to work? What other problems I might run into? E.g. does not running compaction hurt the performance or consume significantly more disk space (than if I did handle the versioning manually)?

• How to make some simple GUI controls?

  - by daniels

  I need to make a DirectX or OpenGL app and i will need a custom GUI for that. I think a button, a input text box, a list box (that will need a scroll bar as there will be more items that can fit on the screen) and a slider control will be enough. I know about CeGUI framework but i just don't like it, way too many XML files for my taste. My question is where should i start in learning how to do this custom GUI controls, are there any tutorial available or any material that could get me started? I haven't done a GUI contol myself before.

• SQL Compare-Like tool for Oracle?

  - by Hitchhiker

  We're a .NET team which uses the Oracle DB for a lot of reasons that I won't get into. But deployment has been a bitch. We are manually keeping track of all the changes to the schema in each version, by keeping a record of all the scripts that we run during development. Now, if a developer forgets to check-in his script to the source control after he ran it - which is not that rare - at the end of the iteration we get a great big headache. I hear that SQL Compare by Red-Gate might solve these kind of issues, but it only has SQL Server support. Anybody knows of a similar tool for Oracle? I've been unable to find one.

• ASP.net Treeview/Listview combination or alternative: Tutorials? Help?

  - by jlrolin

  I need to create an ASP.net page that has a control on the page that has a five-level TreeView on the left side of the page, and accounting balances on the right side the coincide with each breakdown in the tree. Top level is company, next is group, next is program, etc... and the balances break down accordingly. I've seen that there are controls out there such as TreeView/ListView combination controls that can do this. Is there any tutorials or help out there on how to go about accomplishing this without paying for controls? Could a treeview do this alone by spanning data across the entire length of the columns since every level will have totals on it?
