  • Error : The Type Initializer of Deamon.Global threw an exception in c#

    - by srk
    I am using the below class file, where some variables are declared to use in the entire application. Now i used that variable [BlockLogOut] in another class file to make the value True. I just put this below line and getting error in it.. "TypeInitializationException" Global.BlockLogOut = True; The wired thing is, it was working fine for many months and i am getting this error now on the above line. Of course i was modifying some other stuffs in the application, but surely not this class file. What would have been the problem ? namespace Daemon { class Global { public static bool BlockLogOut = false; } }

  • VIrtual class problem

    - by ugur
    What i think about virtual class is, if a derived class has a public base, let's say, class base, then a pointer to derived can be assigned to a variable of type pointer to base without use of any explicit type conversion. But what if, we are inside of base class then how can we call derived class's functions. I will give an example: class Graph{ public: Graph(string); virtual bool addEdge(string,string); } class Direct:public Graph{ public: Direct(string); bool addEdge(string,string); } Direct::Direct(string filename):Graph(filename){}; When i call constructor of Direct class then it calls Graph. Now lets think Graph function calls addedge. Graph(string str){ addedge(str,str); } When it calls addedge, even if the function is virtual, it calls Graph::edge. What i want is, to call Direct::addedge. How can it be done?

  • Changing text size on a ggplot bump plot

    - by Tom Liptrot
    Hi, I'm fairly new to ggplot. I have made a bumpplot using code posted below. I got the code from someones blog - i've lost the link.... I want to be able to increase the size of the lables (here letters which care very small on the left and right of the plot) without affecting the width of the lines (this will only really make sense after you have run the code) I have tried changing the size paramater but that always alter the line width as well. Any suggestion appreciated. Tom require(ggplot2) df<-matrix(rnorm(520), 5, 10) #makes a random example colnames(df) <- letters[1:10] Price.Rank<-t(apply(df, 1, rank)) dfm<-melt(Price.Rank) names(dfm)<-c( "Date","Brand", "value") p <- ggplot(dfm, aes(factor(Date), value, group = Brand, colour = Brand, label = Brand)) p1 <- p + geom_line(aes(size=2.2, alpha=0.7)) + geom_text(data = subset(dfm, Date == 1), aes(x = Date , size =2.2, hjust = 1, vjust=0)) + geom_text(data = subset(dfm, Date == 5), aes(x = Date , size =2.2, hjust = 0, vjust=0))+ theme_bw() + opts(legend.position = "none", panel.border = theme_blank()) p1 + theme_bw() + opts(legend.position = "none", panel.border = theme_blank())

  • How do I use namespaces in Backbone with RequireJs

    - by dev.pus
    I am unsure how I use namespaces in an modularized (RequireJs) Backbone environment. I have thought a bit how it could look like but am totally unsure if this is the right way. app.js (getting executed by main.js) define('App', ['underscore', 'backbone', 'Router'], function( _, Backbone, Router){ function initialize(){ var app = {}; // app is the global namespace variable, every module exists in app app.router = new Router(); // router gets registered Backbone.history.start(); } return { initialize: initialize } }); messages.js define('MessageModel', ['underscore', 'backbone', 'App'], function(_, Backbone, App){ App.Message.Model; // registering the Message namespace with the Model class App.Message.Model = Backbone.Model.extend({ // the backbone stuff }); return App; }); Is this the right approach or am I fully on the wrong way (if yes please correct me!)

    - by metashockwave
    I'm trying to sort records in the gridview right after a radio button is selected.

  • ASP.net VB Timers

    - by Tom Gullen
    I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable. In ASP it was easy with the Timer object, but in .net I can't find anything on Google. I need something along the lines of: Dim startTime Dim endTime startTime = now() doBigFunction() endTime = now() response.write("That took " & endTime - startTime & " milliseconds") Cheers!

    - by Simon
    I'd like to use embedded resources in my XSLT file, but while invoking 'document(...)' C# complains that "Error during loading document ..."

  • IB not responding to UIImageView moving

    - by Rudiger
    This an incredibly annoying bug. I had a imageView and 2 Labels in a customCell nib. I changed the locations of all of them in the nib and the labels moved, view didn't. I've cleaned my targets, deleted everything relating to it the library, deleted the cell completely, reset the simulator, built it on a different target (3.1.2) and it still compiles the image in the same stupid spot. Can anyone help this is nuts. Sorry for being blunt but completely frustrated. Edit: I have deleted the nib and created it over again by hand, but with the same names. Doesn't fix it. I've checked to see if im moving it somewhere in the code and no dice.

  • Is there a more efficient way to set variables on a RadioButton's CheckChanged event?

    - by C Patton
    I have 16 radio buttons in an application of mine.. I have to set a variable based on which one was selected.. and I've produced some very ugly code doing this.. private void Foo_CheckedChanged(object sender, EventArgs e) { convertSource = 1; } private void Bar_CheckedChanged(object sender, EventArgs e) { convertSource = 2; } private void Baz_RadioButton_CheckedChanged(object sender, EventArgs e) { convertSource = 3; } Now, I've been thinking about it and to be honest I thought there might have been a way to do it with a switch.. I just can't conceptualize it in my mind. If anyone could show me a more efficient way of doing this, I'd really appreciate it. It's just really bugging me that such a simple thing as this is taking up fifty to seventy lines of code. thanks, cpatton

  • how to hide table columns in jQuery?

    - by understack
    I've a table with lots of columns. I want to give users the option to select columns to be shown in table. These options would be checkboxes along with the column names. So how can I hide/unhide table columns based on checkboxes? Would hiding (using .hide()) each td in each row work? May be I can assign checkbox value to the location of column in table. So first checkbox means first column and so on. And then recursively hide that 'numbered' td in each row. Would that work?

  • Python nested function scopes

    - by Thomas O
    I have code like this: def write_postcodes(self): """Write postcodes database. Write data to file pointer. Data is ordered. Initially index pages are written, grouping postcodes by the first three characters, allowing for faster searching.""" status("POSTCODE", "Preparing to sort...", 0, 1) # This function returns the key of x whilst updating the displayed # status of the sort. ctr = 0 def keyfunc(x): ctr += 1 status("POSTCODE", "Sorting postcodes", ctr, len(self.postcodes)) return x sort_res = self.postcodes[:] sort_res.sort(key=keyfunc) But ctr responds with a NameError: Traceback (most recent call last): File "PostcodeWriter.py", line 53, in <module> w.write_postcodes() File "PostcodeWriter.py", line 47, in write_postcodes sort_res.sort(key=keyfunc) File "PostcodeWriter.py", line 43, in keyfunc ctr += 1 UnboundLocalError: local variable 'ctr' referenced before assignment How can I fix this? I thought nester scopes would have allowed me to do this. I've tried with 'global', but it still doesn't work.

  • 503 (Server Unavailable) WebException when loading local XHTML file

    - by kcoppock
    Hello! So I'm currently working on an ePub reader application, and I've been reading through a bunch of regular XML files just fine with System.Xml and XmlDocument: XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(Path.Combine(Directory.GetCurrentDirectory(), "META-INF/container.xml")); XmlNodeList xnl = xmldoc.GetElementsByTagName("rootfile"); However, now I'm trying to open the XHTML files that contain the actual book text, and they're XHTML files. Now I don't really know the difference between the two, but I'm getting the following error with this code (in the same document, using the same XmlDocument and XmlNodeList variable) xmldoc.Load(Path.Combine(Directory.GetCurrentDirectory(), "OEBPS/part1.xhtml")); "WebException was unhandled: The remote server returned an error: (503) Server Unavailable" It's a local document, so I'm not understanding why it's giving this error? Any help would be greatly appreciated. :) I've got the full source code here if it helps: http://drop.io/epubtest (I know the ePubConstructor.ParseDocument() method is horribly messy, I'm just trying to get it working at the moment before I split it into classes)

  • How can I get a value out of a jQuery object?

    - by Jannis
    I am returning some data (example below) and saving it to a jQuery object (or is this an array and I am confusing the two?) when I log the variable that is the object it has the values I am looking for but how do I access the data inside this object? code $itemPosition = { 'top': $item.offset().top, 'left':$item.offset().left }, console.log($itemPosition); This would log out (the in this case expected) top: 0 & left: 490. But how can I know work with those values? Also, while this it is probably obvious I am still in the early stages of learning jQuery/Javascript rest assured that reference books are on their way, but so far the SO community has been invaluable to my learning, so thanks for reading!

  • Is SynchronizationContext.Post() threadsafe?

    - by cyclotis04
    This is a pretty basic question, and I imagine that it is, but I can't find any definitive answer. Is SynchronizationContext.Post() threadsafe? I have a member variable which holds the main thread's context, and _context.Post() is being called from multiple threads. I imagine that Post() could be called simultaneously on the object. Should I do something like lock (_contextLock) _context.Post(myDelegate, myEventArgs); or is that unnecessary? Edit: MSDN states that "Any instance members are not guaranteed to be thread safe." Should I keep my lock(), then?

  • Adding Item to DataBound Drop Down List

    - by Stephen
    Yes, I have read most of the topics here, but I can't find an answer that works. I have Three drop-down lists. The first is databound to grab distinct experiment names. The user selects, page posts back, and the second drop-down menu displays distinct time points. This is where I need help. I need to add an item to THAT drop-down list whose ID, DataTextField, DataValueField are all TimePt. Seems simple, but I can't get it to work. protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack) { TimePt.DataSource = TimePTDD; TimePt.DataValueField = "TimePt"; TimePt.DataTextField = "TimePt"; TimePt.DataBind(); TimePt.Items.Insert(0, new ListItem("--Select---", "0")); TimePt.SelectedIndex = 0; } } I'm missing sometthing.

  • Resharper and var

    - by Refracted Paladin
    I have Resharper 4.5 and have found it invaluable so far but I have a concern; It seems to want to make every variable declaration implicit(var). As a relativly new developer how much should I trust ReSharper when it comes to this? Take the below code snippet from a method that Paints Tab Headers. TabPage currentTab = tabCaseNotes.TabPages[e.Index]; Rectangle itemRect = tabCaseNotes.GetTabRect(e.Index); SolidBrush fillBrush = new SolidBrush(Color.Linen); SolidBrush textBrush = new SolidBrush(Color.Black); StringFormat sf = new StringFormat { Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center }; Resharper wants me to change all 5 of those to var. I have read the following similar post,Use of var keyword in C#, but I would like to know from a Resharper standpoint. Thanks!

  • Creating an Excel file using .NET (C#) - Problems with columns headers!

    - by tsocks
    Hello, I want to create & fill a .xls file using ADO.NET or LINQ, but I do not want to have the columns names in the first row. I just want to insert rows starting in row no. 1. I know I have to insert colums first, but... is there a way to 'hide' those columns headers? The problem is that, in first row of my spreadsheet, I must have only two values (one in A1 and the other in B1), but in the remaining rows I'll be inserting more than just two values (maximum 15 columns). I'm open to suggestions/hacks/tricks even if that's not the best way of doing this. Thanks!

  • Pulling out two separate words from a string using reg expressions?

    - by Marvin
    I need to improve on a regular expression I'm using. Currently, here it is: ^[a-zA-Z\s/-]+ I'm using it to pull out medication names from a variety of formulation strings, for example: SULFAMETHOXAZOLE-TRIMETHOPRIM 200-40 MG/5ML PO SUSP AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE AMOXICILLIN TRIHYDRATE 125 mg ORAL TABLET, CHEWABLE AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE Amoxicillin 1000 MG / Clavulanate 62.5 MG Extended Release Tablet The resulting matches on these examples are: SULFAMETHOXAZOLE-TRIMETHOPRIM AMOX TR/POTASSIUM CLAVULANATE AMOXICILLIN TRIHYDRATE AMOX TR/POTASSIUM CLAVULANATE Amoxicillin The first four are what I want, but on the fifth, I really need "Amoxicillin / Clavulanate". How would I pull out patterns like "Amoxicillin / Clavulanate" (in fifth row) while missing patterns like "MG/5 ML" (in the first row)?

  • struts validation problem in IE

    - by user265201
    I am using Struts 2.1.8 and facing validation problem in IE. I am getting the following error An exception occurred: Error. Error message: Invalid argument. I tried out to figure out the cause and found the following. My generated javascript code is: field = form.elements['district.name']; var error = "Enter only alphabets for district"; if (continueValidation && field.value != null && !field.value.match("^[a-zA-Z ]*$")) { addError(field, error); errors = true; } I tried to mock up by putting the same code in a function and calling it in onclick event. The method addError() throws the exception and the reason is field variable. If I change it to field[0], it works fine. How to fix this error?

  • mouseover detection in NSTableView's NSCell?

    - by Wigwam
    I am wanting to change the text background color on a tableview's cell when it is hovered upon, similar to how AddressBook "highlights" the label of a contact's element when you mouseover the label names. However I cannot figure out how to accomplish... detecting a mouseover on a particular NSCell and... After detecting the cell his hovered upon, highlighting the text in that cell (not highlighting the entire row as if the user selected that row) As NSCell is not a subclass of NSView this seems to be a very difficult task. Any example of this or explanation on how this might be done would be greatly appreciated. Thanks!

  • Multipart question: Mapping between xml and Json using xpath

    - by scope-creep
    This is a JSON mapping question from a json newbie. Currently i'm reading xml using xpath in C#, and the xpath are returning either the element or attribute node values, as is the schema's want. I want to write out some of the returned values into a json formatted file. I know i can faneigle the xpath expression to return the element or attribute names, so I can built the appropriate name/value json structure before serialization, but I was I'm wondering if their was some way of doing a mapping between the xml and json. The xml schema is fairly big, so potentially the mapping will be big, meaning a ton of cumbersom coding to make it work. Is their any way to automap somehow? I was planning to use json.net, which seems flexible enough, although their may be a better approach. Any help would be appreciated. Bob.
