  • How do i reset values of dynamically created controls on ASP .NET c# page?

    - by Euclid
    i have an array of buttons added to a panel control and need to reset them to their original values, is this possible pragmatically? protected void Page_Load(object sender, EventArgs e) { RenderTable(); } private void RenderTable() { Button[] board = new Button[9]; for(int i =0; i <board.Length; i++) { board[i] = new Button(); board[i].Text = " "; board[i].Width= board[i].Height = 50; board[i].Click += PlayerClick; board[i].ID = "pos" + i; Panel1.Controls.Add(board[i]); } }

  • Large ResultSet on postgresql query

    - by tuler
    I'm running a query against a table in a postgresql database. The database is on a remote machine. The table has around 30 sub-tables using postgresql partitioning capability. The query will return a large result set, something around 1.8 million rows. In my code I use spring jdbc support, method JdbcTemplate.query, but my RowCallbackHandler is not being called. My best guess is that the postgresql jdbc driver (I use version 8.3-603.jdbc4) is accumulating the result in memory before calling my code. I thought the fetchSize configuration could control this, but I tried it and nothing changes. I did this as postgresql manual recomended. This query worked fine when I used Oracle XE. But I'm trying to migrate to postgresql because of the partitioning feature, which is not available in Oracle XE. My environment: Postgresql 8.3 Windows Server 2008 Enterprise 64-bit JRE 1.6 64-bit Spring 2.5.6 Postgresql JDBC Driver 8.3-603

  • Execute Oracle RAC cluster commands via Solaris RBAC?

    - by David Citron
    Executing Oracle RAC cluster management commands such as $ORA_CRS_HOME/bin/crs_start requires root permissions. Using Solaris RBAC (Role-Based Access Control), one can give a non-root user permissions to execute those commands, but the commands still fail internally. Example: $pfexec /opt/11.1.0/crs/bin/crs_stop SomeArg CRS-0259: Owner of the resource does not belong to the group. Is there a complete RBAC solution for Oracle RAC or does the executor need to be root? EDIT: Note that my original /etc/security/exec_attr contained: MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start:uid=0 MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start.bin:uid=0 As Martin suggests below, this needed to be changed to add gid=0 as: MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start:uid=0;gid=0 MyProfile:suser:cmd:::/opt/11.1.0/crs/bin/crs_start.bin:uid=0;gid=0

  • Can't check more than one RadioButton across multiple items in a Treeview

    - by Mike Johnston
    I’m using a TreeView control to present a list of Questions. Using the Prism.DataTemplateSelector, I'm loading a View (.xaml file) that represents a single Question into each node in the TreeView. In the View for that question is a ListBox containing RadioButtons (one for each item in a Picklist object that the ListBox is bound to). The radio buttons work as expected for the question, but when I check a RadioButton on another node/question in the TreeView, the check for the button in the Question I was editing before disappears. In other words, I'm only able to check one RadioButton in the whole list of Questions/Items bound to the containing TreeView. How do I group the RadioButtons in the ListBox to the scope of the single question instead of all the questions in the TreeView.

  • How to implement a syndication receiver? (multi-client / single server)

    - by LeonixSolutions
    I have to come up with a system architecture. A few hundred remote devices will be communicating over internet with a central server which will receive data and store it in a database. I could write my own TCP/IP based protocol use SOAP use AJAX use RSS anything else? This is currently seen as one way (telemetry, as opposed to SCADA). Would it make a difference if we make it bi-directional. There are no plans to do so, but Murphy's law makes me wary of a uni-directional solution (on the data plane; I imagine that the control plane is bi-directional in all solutions (?)). I hope that this is not too subjective. I would like a solution which is quick and easy to implement and for others to support and where the general "communications pipeline" from remote deceives to database server can be re-used as the core of future projects. I have a strong background in telecomms protocols, in C/C++ and PHP.

  • Web Application Nat Traversal

    - by pbreault
    We are deploying web applications in java using tomcat on client machines across the country. Once they are installed, we want to allow a remote access to these web applications through a central server, but we do not want our clients to have to open ports on their routers. Is there a way to tunnel the http traffic in a way that the central server can access the web application that is behind the firewall ? The central server has a static ip address and we have full control over it. We don't need to access the filesystem, we only want to access the web application itself through a browser.

  • Are Scala "continuations" just a funky syntax for defining and using Callback Functions?

    - by Alex R
    And I mean that in the same sense that a C/Java for is just a funky syntax for a while loop. I still remember when first learning about the for loop in C, the mental effort that had to go into understanding the execution sequence of the three control expressions relative to the loop statement. Seems to me the same sort of effort has to be applied to understand Continuations (in Scala and I guess probably other languages). And then there's the obvious follow-up question... if so, then what's the point? It seems like a lot of pain (language complexity, programmer errors, unreadable programs, etc) for no gain.

  • jsonp cross domain only working in IE

    - by iboeno
    EDIT: At first I thought it wasn't working cross domain at all, now I realize it only works in IE I'm using jQuery to call a web service (ASP.NET .axmx), and trying to us jsonp so that I can call it across different sites. Right now it is working ONLY in IE, but not in Firefox, Chrome, Safari. Also, in IE, a dialog pops up warning "This page is accessing information that is not under its control..." Any ideas? Here is the code: $.ajax({ type: "POST", url: "http://test/TestService.asmx/HelloWorld?jsonp=?", dataType: "jsonp", success: function(data) { alert(data.prop1); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(XMLHttpRequest.status + " " + textStatus + " " + errorThrown); } }); And the server code is: [ScriptService] public class TestService : System.Web.Services.WebService{ [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public void HelloWorld() { string jsoncallback = HttpContext.Current.Request["jsonp"]; var response = string.Format("{0}({1});", jsoncallback, @"{'prop1' : '" + DateTime.Now.ToString() + "'}"); HttpContext.Current.Response.Write(response); } }

  • The width of a list that contains an embedded matrix grows unexpectedly

    - by Greg Lorenz
    I have a report in reporting services 2005 that includes a list with an embedded matrix and am attempting to put a border on the list, however, when I run the report in visual studio the matrix is growing past the end of the page and therefore the boarder is growing with it causing it to grow into the second page. It appears that there was supposedly a fix for this in reporting services 2000 service pack 1 but I am still experianceing the issue in 2005. The list has a details group that limits the records on a row to 4 using the following expression: =ceiling(rownumber("list1")/4), the matrix has a column group that should recycle those based on the rownumber determined by the list using the following expression: =rowNumber("list1_Details_Group") I have also attempted to put the list in a rectangle in hopes to stop the matrix from growing to no avail. How do I effectivly stop the matrix form growing past the space allowed by the list control?

  • How to create Master/Detail view with two datagrids in ColdFusion

    - by Maklar
    In Coldfusion, I have Master and Detail data that I need to display in two separate cfgrids; like the typical Customers/Orders scenario. My cfgrids are bound to cfc functions which populate the cfgrids. In my current dataset, only one Customer has Orders and when I click on this record in the Master datagrid the Detail datagrid displays the related records. But when I click on a record in the Master datagrid that has no related detail records, the Detail datagrid does not refresh but maintains display of the previous data. Also the search icon within the datagrid's control panel indicates it is searching for values rather than displaying the Refresh icon. Can you please show me how to establish Master and Detail cfgrids where I can see Orders of Customers as I navigate through the Master datagrid? Any and all help will be greatly appreciated! Maklar

  • cross-domain data with AJAX using JSONP

    - by kooshka
    I'm trying to get data from Geobytes. One of the templates returns JSON and I need to cross-domain access it. I wrote these 2 functions function getCountry(ip) { var surl = "http://www.geobytes.com/IpLocator.htm?GetLocation&template=json.txt"; $.ajax({ url: surl, data: '{"ipaddress":"' + ip + '"}', dataType: "jsonp", jsonp: "callback", jsonpCallback: "jsonpcallback" }); } function jsonpcallback(rtndata) { alert(rtndata.message); } The call is executed but I get 1 warning: Resource interpreted as Script but transferred with MIME type text/html: "http://www.geobytes.com/IpLocator.htm?GetLocation&template=json.txt&callback=jsonpcallback&{%22ipaddress%22:%22200.167.254.166%22}&_=1353148931121" 1 Error: Uncaught SyntaxError: Unexpected token : The error is thrown on the returned data at {"geobytes":{"countryid":117, I think is maybe because it's 117 and not "117" but I obviously can't control the returned data How can I fix these 2 issues?

  • the MVCC effect on migration from oracle to db2

    - by Ryan Fernandes
    I have a simple (actually simplified :) ) scenario that is possibly the cause for the headache I've been having for the last few days... My current application (that serves 100's of users) currently uses Oracle as the database. I have no stored procs (I wish actually). Now, I've been asked if the product will work if I migrate to IBM DB2 as the database. So, after taking Oracle for granted all this while.... and having re-read Tom's article on MVCC (Multiversion Concurrency Control) and going through this post stating that DB2 is not 'on the list' or 'just tip-toeing in the area' as it were... I know I can't be sure that the product will work with DB2 as is. Is there no hope.. or is there a nice disclaimer I could use.. ?

  • How to pass an event to a method and then subscribe to it?

    - by Ryan Peschel
    Event Handler public void DeliverEvent(object sender, EventArgs e) { } #1: This Works public void StartListening(Button source) { source.Click += DeliverEvent; } #2: And so does this.. public void StartListening(EventHandler eventHandler) { eventHandler += DeliverEvent; } But in #2, you cannot call the method because if you try something like this: StartListening(button.Click); You get this error: The event 'System.Windows.Forms.Control.Click' can only appear on the left hand side of += or -= Is there any way around that error? I want to be able to pass the event and not the object housing the event to the StartListening method.

  • R: ca plotting text attributes

    - by chasec
    Does anyone know of a way to control the font size/color/weight of the row and column names when plotting a correspondence plot with the ca package? The following code will produce a very nice looking chart, though if there were more attributes (very heavy, super heavy, something more than super heavy) or more classes of workers (peons, underlings, etc) then the graph will get a little cluttered and hard to tell what was what. It would be nice if you could list all the attributes in a separate color than the categories of workers. library(ca) data("smoke") plot(ca(smoke) , map = "symmetric" , what =c("active","active") , mass = c(T,T) , contrib = "absolute" , col = c("red","blue") , pch = c(15,17,15,17) , labels = c(2,2) , arrows = c(T,F) ) Alternatively, does anyone know if there is a way to reproduce something along these lines with ggplot2? I didn't find anything on the website that seemed comparable, but I don't know much about the package. Thanks, -Chase

  • Best practice for Google app engine and Git.

    - by systempuntoout
    I'm developing a small pet project on Google App Engine and i would like to keep code under source control using github; this will allow a friend of mine to checkout and modify the sources. I just have a directory with all sources (call it PetProject) and Google App Engine development server points to that directory. Is it correct to create a Repo directly from PetProject directory or is it preferable to create a second directory (mirror of the develop PetProject directory); in this case, anytime my friend will release something new, i need to pull from Git and then copy the modified files to the develop PetProject directory. If i decide to keep the Repo inside the develop directory, skippin .git on yaml is enough? What's the best practice here?

  • How do I set sys.excepthook to invoke pdb globally in python?

    - by saffsd
    From Python docs: sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr. When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook. http://docs.python.org/library/sys.html How do I modify this globally so the default action is to always invoke pdb? Is there a configuration file I can change? I don't want to wrap my code to do this.

  • What is the best solution to do Reporting on Object data for .NET ?

    - by Peter Fox
    Hi, Our projects are using objects as the data source to reports. Our business layer is returning single objects or IEnumerable. Our reports (quite complex) need to display value-type properties of the object, and its related objects. Typical case would be, from a List, display a master report with category data, then a subreport with data for each Product inside each Category, then a subreport for each Part of each Product, and so on. Reporting from the database is not an option for us. We have tried so far - Reporting Services : works but have to mess around with the XML definition of the report to define the datasource classes, very hard to work with if you use an object datasource, architecturally not too clean - Telerik Reports : quite nice (esp., nice architecture) but seems to have problems with complex reports (master/sub), does not give great paging control, rumored to have performance/crash problems (immature product). Does anyone know a good reporting solution that can be integrated in an ASP.NET application and works well with objects as datasources ?

  • What HTTP headers are required to refresh a page on back button.

    - by cantabilesoftware
    I'm trying to get a page to refresh when navigated to from the back button. From what I understand after reading around a bit I should just need to mark the page as uncacheable but I can't get any browsers to refresh the page. These are the headers I've currently got: Cache-Control:no-cache Connection:keep-alive Content-Encoding:gzip Content-Length:1832 Content-Type:text/html; charset=utf-8 Date:Mon, 07 Jun 2010 14:05:39 GMT Expires:-1 Pragma:no-cache Server:Microsoft-IIS/7.5 Vary:Accept-Encoding Via:1.1 smoothwall:800 (squid/2.7.STABLE6) X-AspNet-Version:2.0.50727 X-AspNetMvc-Version:2.0 X-Cache:MISS from smoothwall X-Powered-By:ASP.NET Why would the browser pull this page from it's browser history and not refresh it?

  • E.cancel loop in Visual basic

    - by Ahmed
    I am making an server control application ( simple with some buttons to start/stop the server ) And when the user wants to close the application there will be prompted an confirm box. Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing Dim response As Integer response = MsgBox("Are you sure you want to stop the server", vbYesNo, "Stop Server ?") If response = vbYes Then Shell("cscript ""stop.vbs""", 1) Close() Else e.Cancel = True End If End Sub That is the code I have now. But when I start the application and close it with the X button or with "Close Window" I will be prompted with the question until I click on no, then it will close. It's a loop and it stops when you first click on yes then on no. Can someone help me with solving this ?

  • Search Lucene with precise edit distances

    - by askullhead
    I would like to search a Lucene index with edit distances. For example, say, there is a document with a field FIRST_NAME; I want all documents with first names that are 1 edit distance away from, say, 'john'. I know that Lucene supports fuzzy searches (FIRST_NAME:john~) and takes a number between 0 and 1 to control the fuzziness. The problem (for me) is this number does not directly translate to an edit distance. And when the values in the documents are short strings (less than 3 characters) the fuzzy search has difficulty finding them. For example if there is a document with FIRST_NAME 'J' and I search for FIRST_NAME:I~0.0 I don't get anything back.

  • What exactly does SCM stand for?

    - by mike g
    In the software world, it seems to me that SCM is an unfortunately overloaded acronym. It can mean:- Source Code Management Software Configuration Management Which one of these is the dominant term? Do they mean the same thing? To me Source Code Management is essentially synonymous with Version Control. Whereas Software Configuration Management is a larger subject, which potentially includes Build and Release Management as well. However looking on Wikipedia, it lists Subversion as a Software Configuration Management tool, which is at most only tangentially true. Build and Software Management has come up before, but nothing definitive has been said on the matter, unfortunately.

  • Where to place java applet policy file?

    - by makdere
    Hi all, I am working on an artificial intelligence project which is a logic game and aims two user connecting to the server on the network who acts as an Admin and then start to play one by one. In order to create connections, i have a server code which is just listening on localhost:8000 and assigning team values to the clients as they arrive. After connecting, clients make their move under Admin's control. The question is that when i try to put my code to work in the browser it fails with the following error: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:8000 connect,resolve) Even though i have created my own policy, first granting only Socket access permission to the codebase of my project folder (file:///home/xxx/projects/-), after it didnt work i granted all permissions from all codebase. I tried placing my policy file both in the home directory and in the same directory where my applet code resides. Appreciate any tips, thanks.
