  • Problem using a costum server control in a aspx

    - by gre3ns0ul
    Hi guys, i am having a issue. I already developed one class (my custom gridview) and i want use it on a .aspx That class is defined in app_code and compiled to the dll of the project. namespace MyCostumControls{  public class DropDownPagingGridView : GridView{ ... I already registered the control on the aspx page using <%@ Register Namespace="MyCostumControls" TagPrefix="ctrl" % and i can use in the page and works ok.. But i'm watching one problem. That class contains methods defined by me, than when i try to call them in code-behind sayd to me than they're not defined. In designed i don't see the reference to MyCostumControls, and when i try declare one field using protected global::MyCostumControls.MyCostumControls ddl_gv_errors, i cannot access to MyCostumControls namespace, Is because he's compiled to the project dll? I can access to all namespaces than are not contained in app_code. Solutions? Apreciate. Thanks

  • How to expose information about a running .NET exe?

    - by Doug
    I have a .NET exe that I wrote and it has a couple properties that I made public and want to expose. I want to shell this exe (Process.Start()) and then somehow reference this exe and get access to these public properties. These properties expose information about the running exe. I know how to shell to the exe. And I know how to add a reference to the exe from my project that I want to use this object. But how do I get access to the properties of this running exe? I hope I am explaining myself well. If you do know the answer maybe you could just tell me what the standard method is to expose properties of a running exe to another application at run-time. Thanks for any help!

  • Core Data-Linking one-to-many relationships

    - by Stelmate
    I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

  • Activity.findViewById returning null sporadically

    - by adstro
    From the crash logs that I am getting from the Android market, I can see that some of my users are getting Force Closes caused by NullPointerExceptions when my code tries to access views that are in my application. In one example, my activity makes a call to findViewById() in onCreate() after I call setContentView(). I get an NPE when I try to access the view after the call to findViewById() (still in onCreate). What has me really scratching my head is that this does not happen all of the time (in fact most of the time the code acts as I would expect), but enough to have me concerned. I could add code to always check for null and avoid the NPE, but I would like to understand what could be causing the sporadic behavior. Does anyone know what could be causing this?

  • Beginners PHP / mySQL question

    - by Reg H
    I'm brand new to PHP & MySQL, and one function I'm creating needs to access a large table or database. I've created the database and it's currently in a MySQL table, which I'm accessing with no problem. The table is 11,000 rows in length, with 8 columns (all text less than 8 characters long) - it's static, and will never change. Without getting too particular, my users will hit a button which will trigger scripts to access the data, say 500 times or more. So in general would it be better practice to include all of this data in a big 'switch' or 'if... then' conditional right in my scripts, rather than opening and accessing the database connection hundreds, or maybe even thousands of times? It just seems like that might be a bottleneck waiting to happen. Thanks!

  • Prevent .htaccess syntax error

    - by seengee
    Hi, As part of one our system's we enable a user in the backoffice to add a block of 301 redirects should they need to. This is just a textarea which then populates a specific area of a .htaccess file. As much as this may seem insecure it has only previously used internally by people who know what they are doing but for various reasons they cannot access the specific file. We need now to allow more access to this function, not for the general public, but for people that probably have far less knowledge of regexp etc and syntax in htaccess files. Obviously the major concern here is the user enters some bad syntax and makes their entire site, including the backoffice where they could fix the issue, totally inaccessible without manual intervention. What approaches can i take to make sure that they do not break their site? A htaccess syntax check? copy the file elsewhere and check it doesnt generate a 500 error (with cURL or similar)?. Would welcome any ideas. Thanks.

  • Using directory traversal attack to execute commands

    - by gAMBOOKa
    Is there a way to execute commands using directory traversal attacks? For instance, I access a server's etc/passwd file like this http://server.com/..%01/..%01/..%01//etc/passwd Is there a way to run a command instead? Like... http://server.com/..%01/..%01/..%01//ls ..... and get an output? EDIT: To be clear here, I've found the vuln in our company's server. I'm looking to raise the risk level (or bonus points for me) by proving that it may give an attacker complete access to the system

  • Can a raw Lucene index be loaded by Solr?

    - by wynz
    Some colleagues of mine have a large Java web app that uses a search system built with Lucene Java. What I'd like to do is have a nice HTTP-based API to access those existing search indexes. I've used Nutch before and really liked how simple the OpenSearch implementation made it to grab results as RSS. I've tried setting Solr's dataDir in solrconfig.xml, hoping it would happily pick up the existing index files, but it seems to just ignore them. My main question is: Can Solr be used to access Lucene indexes created elsewhere? Or might there be a better solution?

  • how to use ByteArrayOutputStream and DataOutputStream simultaneously (Java)

    - by Manuel
    Hi! I'm having quite a problem here, and I think it is because I don't understand very much how I should use the API provided by Java. I need to write an int and a byte[] into a byte[] I thought of using a DataOutputStream to solve the data writing with writeInt(int i) and write(byte[] b), and to be able to put that into a byte array, I should use ByteArrayOutputStream's method toByteArray(). I understand that this classes use the Wrapper pattern, so I had two options: DataOutputStream w = new DataOutputStream(new ByteArrayOutputStream()); or ByteArrayOutputStream w = new ByteArrayOutputStream(new DataOutputStream()); but in both cases, I "loose" a method. in the first case, I can't access the toByteArray method, and in the second, I can't access the writeInt method. How should I use this classes together?

  • Are sessions modifiable by the client/user?

    - by Sev
    In my PHP Web-App I use sessions to store the user's data. For exmaple, if a user logs in, then an instance of the User class is generated and stored in a Session. I have access levels associated with each user to determine their privileges. Store the user in a session by: $_SESSION['currentUser'] = new User($_POST['username']); For example: if($_SESSION['currentUser'] -> getAccessLevel() == 1) { //allow administration functions } where getAccessLevel() is simply a get method in the User class that returns the _accesslevel member variable. Is this secure? Or can the client somehow modify their access level through session manipulation of some sort?

  • Database that accesses a website.?

    - by Alec
    Hi Guys What application should I use that is able to automatically access a website to gather information? Basically I have a database that completes calculations for me; however I have to manually gather the parameters from a website and input these into my database. What I would like is have an application that will take my input say the name of a product, access the website, add this name into a search box on a website, complete the search and then extract the desired information from the web page returning the results to my application to complete the calculation thus presenting me with the result. This is a little out of my depth but I’m willing to learn no matter how complicated the software. Cheers for your help.

  • From a Java programming perspective, what difference does multicast make to a networking program?

    - by pnut butter
    My manager has asked me to assess what changes would be required to add multicast support to a socket-based TCP/IP networking program that is part of a trading system. As far as I can tell, from the perspective of a Java program, it doesn't seem to matter too much whether the program is unicast or multicast. Doesn't the Java networking API make all of this transparent? By this I mean, wouldn't the change be a simple one of simply adding additional destinations for the outgoing connections?

    I have an activity with two buttons, start and stop. If the user press the start button a service is created using Context.startService. And the stop button calls Context.stopService. I want the stop button to be the only way to destroy the service. Now, if i end the activity using a task manager, the service is killed as well. Is there any way to avoid this?

  • How to avoid accidental deletions of databases in Lotus Notes?

    - by Saili
    I have always worried about users deleting lotus notes databases by accident. We had one such case last week and I want to know how we can lock the databases so that users cannot delete them. Is there a way in Lotus Notes - either at the Db level or server level where we can set up the database so that only the administer of the db or the user with Manager access can delete the database? Thanks!

  • How do you pass objects between View Controllers in Objective-C?

    - by editor
    I've been trudging through some code for two days trying to figure out why I couldn't fetch a global NSMutableArray variable I declared in the .h and implemented in .m and set in a the viewDidLoad function. It finally dawned on me: there's no such thing as a global variable in Objective-C, at least not in the PHP sense I've come to know. I didn't ever really read the XCode error warnings, but there it was, even if not quite plain English: "Instance variable 'blah' accessed in class method." My question: What am I supposed to do now? I've got two View Controllers that need to access a central NSMutableDictionary I generate from a JSON file via URL. It's basically an extended menu for all my Table View drill downs, and I'd like to have couple other "global" (non-static) variables. Do I have to grab the JSON each time I want to generate this NSMutableDictionary or is there some way to set it once and access it from various classes via #import? Do I have to write data to a file, or is there another way people usually do this?

  • How to find the real problem line in my code with Application Verifier ?

    - by Newbie
    I am now trying to use this Application Verifier debugging tool, but i am stuck, first of all: it breaks the program at a line that is simple variable set line (s = 1; for example) Secondly, now when i run this program under debugger, my program seems to have changed its behaviour: i am drawing image, and now one of the colors has changed o_O, all those parts of the image that i dont draw on, has changed the color to #CDCDCD when it should be #000000, and i already set the default color to zero, still it becomes to #CDCDCD. How do i make any sense to this? Here is the output AV gave me: VERIFIER STOP 00000002: pid 0x8C0: Access violation exception. 14873000 : Invalid address causing the exception 004E422C : Code address executing the invalid access 0012EB08 : Exception record 0012EB24 : Context record AVRF: Noncontinuable verifier stop 00000002 encountered.
