  • System.ArgumentException: Invalid hex character at DecryptAssemblyResource

    - by Radu094
    My webapp is trowing these exceptions intermitently ever since we migrated to Mono + Apache: The error sounds more like a problem reading/processing some assembly, so I was wondering if I should be worried that there might be a problem with the hard-drive? System.ArgumentException: Invalid hex character at System.Web.Configuration.MachineKeySectionUtils.ToHexValue (Char c, Boolean high) [0x00000] in <filename unknown>:0 at System.Web.Configuration.MachineKeySectionUtils.GetBytes (System.String key, Int32 len) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.GetBytes (System.String val) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.DecryptAssemblyResource (System.String val, System.String& asmName, System.String& resName) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.ProcessRequest (System.Web.HttpContext context) [0x00000] in <filename unknown>:0 at System.Web.Handlers.ScriptResourceHandler.System.Web.IHttpHandler.ProcessRequest (System.Web.HttpContext context) [0x00000] in <filename unknown>:0 at System.Web.HttpApplication+<Pipeline>c__Iterator2.MoveNext () [0x00000] in <filename unknown>:0 at System.Web.HttpApplication.Tick () [0x00000] in <filename unknown>:0 Method: Void Application_Error(System.Object, System.EventArgs) at File: at Line Number: 0 Method: Void ProcessError(System.Exception) at File: at Line Number: 0 Method: Void Tick() at File: at Line Number: 0 Method: Void Start(System.Object) at File: at Line Number: 0 Method: Void System.Web.IHttpHandler.ProcessRequest(System.Web.HttpContext) at File: at Line Number: 0 Method: Void Process(System.Web.HttpWorkerRequest) at File: at Line Number: 0 Method: Void RealProcessRequest(System.Object) at File: at Line Number: 0 Method: Void ProcessRequest(System.Web.HttpWorkerRequest) at File: at Line Number: 0 Method: Void ProcessRequest() at File: at Line Number: 0 Method: Void ProcessRequest(Mono.WebServer.MonoWorkerRequest) at File: at Line Number: 0 Method: Void ProcessRequest(Int32, System.String, System.String, System.String, System.String, System.String, Int32, System.String, Int32, System.String, System.String[], System.String[], System.Object) at File: at Line Number: 0 Method: Void InnerRun(System.Object) at File: at Line Number: 0 Method: Void Run(System.Object) at File: at Line Number: 0

  • Facebook Connect: with no javascript?

    - by nafe
    Is it possible to write a website that uses Facebook connect without JavaScript? I have a site set up that works great using XFBML but this (obviously) fails when I visit with JavaScript disabled. I have a feeling that this is possible using the REST-api for Facebook but I'd still appreciate some pointers. There was a discussion about this on the Facebook forum.

  • Caching web page data, Database or File

    - by Mahdi
    I am creating an RSS reader application that requests the RSS from my server. I mean, the RSS is first downloaded to my server, then application downloads it from my server. I want to create RSS cache for this. And for example, each RSS would be refreshed every 1 minute. So, If 10 users request RSS of example.com in 1 minute, my server will download it only for the first time, and in other 9 requests, RSS will be loaded from cache. My question is, Should I use a Database (MSSQL) for this purpose? or I should use files? I have no limit in Database size nor in file size... EDIT: I'm using ASP.NET for the server.

  • Problem in retrieving the ini file through web page

    - by MalarN
    Hi All, I am using an .ini file to store some values and retrieve values from it using the iniparser. When I give (hardcode) the query and retrive the value through the command line, I am able to retrive the ini file and do some operation. But when I pass the query through http, then I am getting an error (file not found), i.e., the ini file couldn't be loaded. Command line : int main(void) { printf("Content-type: text/html; charset=utf-8\n\n"); char* data = "/cgi-bin/set.cgi?pname=x&value=700&url=http://IP/home.html"; //perform some operation } Through http: .html function SetValue(id) { var val; var URL = window.location.href; if(id =="set") { document.location = "/cgi-bin/set.cgi?pname="+rwparams+"&value="+val+"&url="+URL; } } .c int * Value(char* pname) { dictionary * ini ; char *key1 = NULL; char *key2 =NULL; int i =0; int val; ini = iniparser_load("file.ini"); if(ini != NULL) { //key for fetching the value key1 = (char*)malloc(sizeof(char)*50); if(key1 != NULL) { strcpy(key1,"ValueList:"); key2 = (char*)malloc(sizeof(char)*50); if(key2 != NULL) { strcpy(key2,pname); strcat(key1,key2); val = iniparser_getint(ini, key1, -1); if(-1 == val || 0 > val) { return 0; } } else { //error free(key1); return; } } else { printf("ERROR : Memory Allocation Failure "); return; } } else { printf("ERROR : .ini File Missing"); return; } iniparser_freedict(ini); free(key1); free(key2); return (int *)val; } void get_Value(char* pname,char* value) { int result =0; result = Value(pname); printf("Result : %d",result); } int main(void) { printf("Content-type: text/html; charset=utf-8\n\n"); char* data = getenv("QUERY_STRING"); //char* data = "/cgi-bin/set.cgi?pname=x&value=700&url=http://10.50.25.40/home.html"; //Parse to get the values seperately as parameter name, parameter value, url //Calling get_Value method to set the value get_Value(final_para,final_val); } * file.ini * [ValueList] x = 100; y = 70; When the request is sent through html page, I am always getting .ini file missing. If directly the request is sent from C file them it works fine. How to resolve this?

  • How to go about reading a web page lazily in Clojure

    - by Rayne
    I and a friend recently implemented link grabbing in my Clojure IRC bot. When it sees a link, it slurp*s the page and grabs the title from the page. The problem is that it has to slurp* the ENTIRE page just to grab the link. How does one go about reading a page lazily until the first ?

  • Daily, Weekly and Monthly Page View Counter

    - by Jens Fahnenbruck
    I'm building a website with user generated content. On the home page I want to show a list of all created items, and I want to be able to sort them by a view counter. That's sound easy, but I want multiple counters. I want to know which was the most visited item in the last day, last week or last months or overall. My first Idea was to create 4 counter columns in the item's DB-Table. One for each of daily, weekly, monthly and overall, and the create a cron job, that clears the daily counter every 24 hours, the weekly counter every 7 days and so on. But my problem with this is, what happens if I want to know which was the most viewed item of the week, just after the weekly counter got cleared? What I need is an efficient way to create a continous counter, which got reduced for every page view that is too old, and increased for every new page view. Right now I'm thinking of a solution with the redis server, but I have no solution yet. I'm just looking for a general idea here, but FYI I'm developing this application in Ruby on Rails.

  • Can't get to Pex download (or visual studio 2010)

    - by Vaccano
    I know this is probably not a "True" stackoverflow question, but here it is anyway: Is anyone able to get to the MSDN Download of Visual Studio 2010? I just get "Your search did not match any products." when I click on the New Downloads-Visual Studio 2010 link. I was able to download Visual Studio on Monday. But it is gone now. That is not really my issue though. That page is also where the pex download is. With that page down I can't download pex either. (I checked with a co-worker (who is having the same issue) before posting. So I know it is not just me.)

  • Cladogram, tree of life, cladistics, taxonomy in JS or canvas?

    - by boblet
    Good people - I need some help to find a way to create an interactive cladogram or phylogenetic tree (yes, I have read all related posts, and do not find what I am looking for). The thing is, I need the nodes to be name-able. An example would be something like this Most scripts I find are either applets, flash, or simply do not show the node classification, ie it would skip "feliformia" in this example. This is useless to me, as I would then end up with carnivore - anonymous node - anonymous node - anonymous node - tiger, and that is not good. This tree will in theory cover all life, so it could get rather large, and get links and names in english and latin from database. So: no flash, no applets. It must be horizontal, no supertrees (circular). I have gone through this http://bioinfo.unice.fr/biodiv/Tree_editors.html but most of them seems to be either old, not displaying sub-node levels, applets, or way too complex. I imagine this would be a delightful job for canvas/jQuery..? And chances are, someone got there before me? Any pointers much appreciated. Note: if anyone out there would like to do something like this as a project, I will be happy to help, even though it would not benefit me for this project.This type of taxonomy is not as simple as it may seem, and I would be happy see this happen.

  • ASP.net Error in Design Mode

    - by stringo0
    I just switched to VS 2010, and upgraded a previous project. I'm getting the following error on a page in design mode for 2 controls: Error Creating Control - ObjectName Object reference not set to an instance of an object. One of them is a simple label, and the other is a ajax update panel. Other pages look fine. When I build and test the app, the page renders fine in the browser and functions fine - the label functions as expected and the content in the update panel works as expected. Any ideas why I'm getting this error? I tried some of the google results to no avail. It'd be great to get this out of the way. Thanks!

  • trying to build a web ui tree from scratch

    - by Susan
    I have seen yahoo ui using div for every node of the tree. Is this a good thing to do. Seems like every node including leaf node is heavily nested. I saw a div, table, tr, td being used for creating a node. Is this necessary. Is there a better way to do the same. I tried to us tr for every node. Are there any issues with this approach Thanks

  • Interaction between Java and Android

    - by Grasper
    I am currently trying to research how to use Android with an existing java based system. Basically, I need to communicate to/from an Android application. The system currently passes object data from computer to computer using ActiveMQ as the JMS provider. On one of the computers is a display which shows object data to the user. What we want to do now is use a phone (running Android) as another option to show this object data to a user with wifi/network access. Ideally we would like to have a native application on the Android that would listen to the ActiveMQ topic and publish to another Topic and read/write/display the object data, but from some research I have done, I am not sure if this is possible. What are some other ways to approach this problem? The android Phone needs to be able to send/receive data. I have been using the AndroidEmulator for testing.

  • Why are there so many data centres in Texas?

    - by jklp
    I've been searching for online hosting recently and have noticed a high concentration of hosting providers in Texas. Just wondering why this is? It couldn't be possibly be because of temperature (I don't think Texas is a particularly cool place to be) or maybe power is cheaper in Texas vs the rest of the States? Or maybe it's just there are laws in place which give hosting providers tax breaks? Would be very interested to find out.

  • How to send complex types from PHP SoapClient to ASP.NET SOAP server?

    - by xaguilars
    Hello I'm having problems sending arrays, structs and arrays of structs from PHP to an ASP.NET SOAP server... Anyone have a sollution for this? I've googled for days and any sollution worked for me. Perphaps I'm forgetting something... There are examples of my code: $client = new SoapClient($options); $pCriteria = new stdClass(); $pCriteria->type=1; $pCriteria->capacity=4; //Test 1 (fail): $resp = $client->GetRooms(array("pCriteria"=>$pCriteria)); //Test 2 (fail): $resp = $client->GetRooms(array("pCriteria"=>new SoapVar($pCriteria, SOAP_ENC_OBJECT, "TCriteria", "http://www.w3.org/2001/XMLSchema"))); print_r($resp); I don't know how to code functions that require an array of TCriteria (TCriteria[], TCriteria_Array type) either... i've tried sending the raw array, a SoapVar with SOAP_ENC_ARRAY encoding and TCriteria_Array type, ... but it does not work (the SOAP server becomes unavaiable and needs to be restarted). I've tried creating classes for the complex types too, instead of stdClass, but not working. I don't know where's the problem. The server admins cannot help me and I haven't found any sollution over internet. I'm a bit desperate hehe. Can you help me please? Can you provide samples of code with the three cases (array of simple data, array of struct and struct) ? Thanks!

  • What is the iPad user agent?

    - by Yoric
    Now that the iPad craze is officially open, it's time to think websites also for the iPad. From what I gather, the iPad is using iPhone OS, but with a different screen resolution from the iPhone/iPod touch. So suddenly, the assumption that iPhone OS = iPhone screen resolution becomes false. Sounds like many sites may have to revise their user-agent - css mapping. So, can anyone with access to the iPad or the iPad SDK give us the user-agent string? Thanks in advance.

  • Machine restricted login access

    - by Sunil Shenoy
    I am working on a project that has a requirement such that login details can only be accessed from one machine at one time. For example, if I grant you access to my website and you login from your home machine, the system will store this settings in a cookie/database. Now if you try the same login details on your work machine or any other machine, the system will not let you log into the system. The login will now only work from home machine. Any suggestions on how to achieve this would be helpful. Any resources you can point me towards would also be appreciated.

  • CrossPage PostBack in series of web pages

    - by Vishnu Reddy
    I had a requirement to pass data between pages in my application. I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving. Following is the idea I was trying to use: PageA.aspx: <form id="frmPageA" runat="server"> <p>Name: <asp:TextBox ID="txtName" runat="server"></asp:TextBox></p> <p>Age: <asp:TextBox ID="txtAge" runat="server"></asp:TextBox></p> <p><asp:Button ID="btnPostToPageB" runat="server" Text="Post To PageB" PostBackUrl="~/PageB.aspx" /></p> </form> In Page A Codebehind file I am creating following public properties of the inputs to access in Page B: public string Name { get { return txtName.Text.ToString(); } } public int Age { get { return Convert.ToInt32(txtAge.Text); } } In PageB.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageA.aspx" % <form id="frmPageB" runat="server"> <asp:HiddenField ID="hfName" runat="server" /> <asp:HiddenField ID="hfAge" runat="server" /> <p><asp:RadioButtonList ID="rblGender" runat="server" TextAlign="Right" RepeatDirection="Horizontal"> <asp:ListItem Value="Female">Female</asp:ListItem> <asp:ListItem Value="Male">Male</asp:ListItem> </asp:RadioButtonList></p> <p><asp:Button ID="btnPostToPageC" runat="server" Text="Post To PageC" PostBackUrl="~/PageC.aspx" /></p> </form> In Page B Codebehind file I am creating following public properties for the inputs to access in Page C: public RadioButtonList Gender { get { return rblGender; } } public string Name { get { return _name; } } public int Age { get { return _age; } } //checking if data is posted from Page A otherwise redirecting User to Page A protected void Page_Load(object sender, EventArgs e) { if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { hfName.Value = PreviousPage.Name; hfAge.Value = PreviousPage.Age.ToString(); } else Response.Redirect("PageA.aspx"); }` in PageC.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageB.aspx" % <form id="frmPageC" runat="server"> <p>Name: <asp:Label ID="lblName" runat="server"></asp:Label></p> <p>Age: <asp:Label ID="lblAge" runat="server"></asp:Label></p> <p>Gender: <asp:Label ID="lblGender" runat="server"></asp:Label></p> <p><asp:Button ID="btnBack" runat="server" Text="Back" PostBackUrl="~/PageA.aspx" /></p> </form> Page C code behind file: if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { lblName.Text = PreviousPage.Name.ToString(); lblAge.Text = PreviousPage.Age.ToString(); lblGender.Text = PreviousPage.Gender.SelectedValue.ToString(); } else Response.Redirect("PageA.aspx");
