  • Merge Cells Vertically in RTF

    - by Jimmy Johnson
    I need to programmatically generate an RTF document with a table that has a column vertically merged., e.x. ______________________________ | merged | foo | hello | | cell | | | | right |--------|----------| | here | bar | world | |_________|________|__________| I looked up online and found that the codes are \clvmgf and \clvmrg but I can't find a decent example. I made a text rtf using MS word, but there's too much junk rtf codes in it for me to figure it out where to put the \clvmgf and \clvmrg to get this to work. Could someone give me an rtf for above example table with no extraneous rtf codes so I can figure out how \clvmgf and \clvmrg works? Any additional explanation would also be greatly appreciated. Thanks!

  • Deploying WCF Tutorial App on IIS7: "The type could not be found"

    - by Jimmy
    Hello, I've been trying to follow this tutorial for deploying a WCF sample to IIS . I can't get it to work. This is a hosted site, but I do have IIS Manager access to the server. However, in step 2 of the tutorial, I can't "create a new IIS application that is physically located in this application directory". I can't seem to find a menu item, context menu item, or what not to create a new application. I've been right-clicking everywhere like crazy and still can't figure out how to create a new app. I suppose that's probably the root issue, but I tried a few other things (described below) just in case that actually is not the issue. Here is a picture of what I see in IIS Manager, in case my words don't do it justice: This is "deployed" at http://test.com.cws1.my-hosting-panel.com/IISHostedCalcService/Service.svc . The error says: The type 'Microsoft.ServiceModel.Samples.CalculatorService', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found. I also tried to create a virtual dir (IISHostedCalc) in dotnetpanel that points to IISHostedCalcService . When I navigate to http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc , then there is a different error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Interestingly enough, if I click on View Applications, it seems like the virtual directory is an application (see image below)... although, as per the error message above, it doesn't work. As per the tutorial, there was no compiling involved; I just dropped the files on the server as follow inside the folder IISHostedCalcService: service.svc Web.config <dir: App_Code> Service.cs service.svc contains: <%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService"%> (I tried with quotes around the c# attribute, as this looks a little strange without quotes, but it made no difference) Web.config contains: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="Microsoft.ServiceModel.Samples.CalculatorService"> <!-- This endpoint is exposed at the base address provided by host: http://localhost/servicemodelsamples/service.svc --> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" /> <!-- The mex endpoint is explosed at http://localhost/servicemodelsamples/service.svc/mex --> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Service.cs contains: using System; using System.ServiceModel; namespace Microsoft.ServiceModel.Samples { [ServiceContract] public interface ICalculator { [OperationContract] double Add(double n1, double n2); [OperationContract] double Subtract(double n1, double n2); [OperationContract] double Multiply(double n1, double n2); [OperationContract] double Divide(double n1, double n2); } public class CalculatorService : ICalculator { public double Add(double n1, double n2) { return n1 + n2; } public double Subtract(double n1, double n2) { return n1 - n2; } public double Multiply(double n1, double n2) { return n1 * n2; } public double Divide(double n1, double n2) { return n1 / n2; } } }

  • Can I convert an ASCII MD5 hashed password into a Unicode MD5 hashed password?

    - by Jimmy Moo Moo
    Hello, I'm looking for help to convert an ASCII MD5 hashed password into a Unicode MD5 hashed password? For example, I'll use the string "password" . When it's converted to an ascii byte array, I get a base64 encoded hash of X03MO1qnZdYdgyfeuILPmQ== When it's converted into a unicode byte array, I get a base64 encoded hash of sIHb6F4ew//D1OfQInQAzQ== All my passwords are stored in an md5 hash that was applied to an ascii byte array, but I'm trying to migrate my application's user data to a system that stores password in an md5 hash that is applied a unicode byte array. In case it's not clear, with the following C#code: var passwordBytes = Encoding.ASCII.GetBytes("password"); var hashAlgorithm = HashAlgorithm.Create("MD5"); var hashBytes = hashAlgorithm.ComputeHash(passwordBytes); My current system uses this, but the system I'm moving to has a diff first time. It usese Encoding.Unicode.GetBytes. Does anybody know how I can convert my passwords? From X03MO1qnZdYdgyfeuILPmQ== into sIHb6F4ew//D1OfQInQAzQ== I'm guessing the answer is that I can't.. the encoding is being done before the hashing, but I thought I'd inquire the bright minds of stackoverflow and see if anybody has a way.

  • Paperclip and Amazon S3 Issue

    - by Jimmy
    Hey everyone, I have a rails app running on Heroku. I am using paperclip for some simple image uploads for user avatars and some other things, I have S3 set as my backend and everything seems to be working fine except when trying to push to S3 I get the following error: The AWS Access Key Id you provided does not exist in our records. Thinking I mis-pasted my access key and secret key, I tried again, still no luck. Thinking maybe it was just a buggy key I deactivated it and generated a new one. Still no luck. Now for both keys I have used the S3 browser app on OS X and have been able to connect to each and view my current buckets and add/delete buckets. Is there something I should be looking out for? I have my application's S3 and paperclip setup like so development: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] test: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] production: bucket: (unique_name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] has_attached_file :cover, :styles => { :thumb => "50x50" }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":class/:id/:style/:filename" Note: I just added the (unique name) bits, those aren't actually there--I have also verified bucket names, but I don't even think this is getting that far. I also have my heroku environment vars setup correctly and have them setup on dev

  • open flash chart rails x-axis issue

    - by Jimmy
    Hey guys, I am using open flash chart 2 in my rails application. Everything is looking smooth except for the range on my x axis. I am creating a line to represent cell phone plan cost over a specific amount of usage and I'm generate 8 values, 1-5 are below the allowed usage while 6-8 are demonstrations of the cost for usage over the limit. The problem I'm encountering is how to set the range of the X axis in ruby on rails to something specific to the data. Right now the values being displayed are the indexes of the array that I'm giving. When I try to hand a hash to the values the chart doesn't even load at all. So basically I need help getting a way to set the data for my line properly so that it displays correctly, right now it is treating every value as if it represents the x value of the index of the array. Here is a screen shot which may be a better description than what I am saying: http://i163.photobucket.com/albums/t286/Xeno56/Screenshot.png Note that those values are correct just the range on the x-axis is incorrect, it should be something like 100, 200, 300, 400, 500, 600, 700 Code: y = YAxis.new y.set_range(0,100, 20) x_legend = XLegend.new("Usage") x_legend.set_style('{font-size: 20px; color: #778877}') y_legend = YLegend.new("Cost") y_legend.set_style('{font-size: 20px; color: #770077}') chart =OpenFlashChart.new chart.set_x_legend(x_legend) chart.set_y_legend(y_legend) chart.y_axis = y line = Line.new line.text = plan.name line.width = 2 line.color = '#006633' line.dot_size = 2 line.values = generate_data(plan) chart.add_element(line) def generate_data(plan) values = [] #generate below threshold numbers 5.times do |x| usage = plan.usage / 5 * x cost = plan.cost * 10 values << cost end #generate above threshold numbers 3.times do |x| usage = plan.usage + ((plan.usage / 5) * x) cost = plan.cost + (usage * plan.overage) values << cost end return values end

  • SerializationException Occurring Only in Release Mode

    - by Calvin Nguyen
    Hi, I am working on an ASP.NET web app using Visual Studio 2008 and a third-party library. Things are fine in my development environment. Things are also good if the web app is deployed in Debug configuration. However, when it is deployed in Release mode, SerializationExceptions appear intermittently, breaking other functionality. In the Windows event log, the following error can be seen: "An unhandled exception occurred and the process was terminated. Application ID: DefaultDomain Process ID: 3972 Exception: System.Runtime.Serialization.SerializationException Message: Unable to find assembly 'MyThirdPartyLibrary, Version=1.234.5.67, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89'.

  • Navigating between pages in a Facebook Platform iframe application

    - by Jimmy Cuadra
    I'm working on a Facebook Platform application that runs in iframe mode, and I'm having trouble understanding how to navigate between pages within the app. Let's say the first page that is loaded within the iframe at my canvas URL is one.html. Within that page, there is a link to two.html that just changes the source of the iframe and doesn't reload the Facebook chrome. When I do this, all the Facebook fb_sig_* query string parameters that Facebook passes to the original page aren't included, and so two.html has no awareness of the connection to Facebook and no ability to make API calls to generate the content for the page. One possible solution would be to manually extract all the Facebook parameters from one.html and append it to the link to two.html myself. This seems really ugly and I figured there had to be a cleaner way. For reference, my application is written in Perl and uses the WWW::Facebook::API module as a client library. I didn't see anything in it that I can use to easily reconstruct the Facebook parameters for use with links in iframe apps. Another possible solution would be to store all the Facebook parameters in a session on my server on the first page load, and just use the values in that session on subsequent page views. But what happens if the data I've stored no longer matches what Facebook would have sent if it were a completely new request (i.e. something in the user's Facebook session changed)? Is there something obvious I'm missing? What is the standard approach to navigating between pages within an iframe app? Facebook's documentation is atrocious and I haven't been able to find anything that clearly explains how this works. I also realize this wouldn't be an issue with an app using FBML instead of an iframe, but my understanding is that iframe apps are now encouraged over FBML apps, though again this seems ambiguous since so much of Facebook's documentation is outdated and contradictory.

  • Python class variables not defined with called from outside module

    - by Jimmy
    I am having some issues with calling a function outside of a module. The scenario is I have a small class library that is using turtle to do some drawing, the function within the module calls the classes also within the module and draws things, etc. This all works fine and dandy when I call the function from within the same file, but if I have another file and call myLib.scene() I get variable undefined errors. Code examples: a class class Rectangle(object): def __init__(self, pen, height=100, width=100, fillcolor=''): self.pen = pen self.height = height self.width = width self.fillcolor = fillcolor def draw(self, x, y): '''draws the rectangle at coordinates x and y''' self.pen.goto(x, y) if self.fillcolor: self.pen.fillcolor(self.fillcolor) self.pen.fill(True) self.pen.down() for i in range(0,4): self.pen.forward(self.height if i%2 else self.width) self.pen.left(90) and the calling function is this def scene(pen): rect = Rectangle(pen) rect.draw(100,100) when I put the line scene(turtle.Turtle()) into the same file I have no issues, the rectangle is drawn and everyone goes home happy. However, if I try to call it from a separate python file like so: myLib.scene(turtle.Turtle()) I get an error: NameError: global name 'pen' is not defined, in the for loop of my draw method. Even if the line above is in the same file it still bombs out. What is going on?

  • How to use Object.GetHashCode() on a type that overrides GetHashCode()

    - by Jimmy
    Hi, I have a class A that implements IEquatable<, using its fields (say, A.b and A.c) for implementing/overriding Equals() and overriding GetHashCode(), and everything works fine, 99% of the time. Class A is part of a hierarchy (class B, C) that all inherit from interface D; they can all be stored together in a dictionary Dictionary, thus it's convenient when they all carry their own default Equals()/GetHashCode(). However, while constructing A I sometime need to do some work to get the values for A.b and A.c; while that's happening, I want to store a reference to the instance that's being built. In that case, I don't want to use the default Equals()/GetHashCode() overrides provided by A. Thus, I was thinking of implementing a ReferenceEqualityComparer, that's meant to force the use of Object's Equals()/GetHashCode(): private class ReferenceEqualityComparer<T> : IEqualityComparer<T> { #region IEqualityComparer<T> Members public bool Equals(T x, T y) { return System.Object.ReferenceEquals(x, y); } public int GetHashCode(T obj) { // what goes here? I want to do something like System.Object.GetHashCode(obj); } #endregion } The question is, since A overrides Object.GetHashCode(), how can I (outside of A) call Object.GetHashCode() for an instance of A? One way of course would be for A to not implement IEquatable< and always supply an IEqualityComparer< to any dictionary that I create, but I'm hoping for a different answer. Thanks

  • Cannot install xdebug with WAMP SERVER 2.1

    Hi all, I use WAMP SERVER 2.1 and select PHP 5.3.3 for my system, so I select xDebug with php_xdebug-2.1.0-5.3-vc6.dll and changed name becoming php_xdebug.dll for easy way to use. Following the instructions: php.ini (in Apache folder) extension=php_xdebug.dll ... zend_extension = "C:/wamp/bin/php/php5.3.3/ext/php_xdebug.dll" xdebug.remote_enable=on xdebug.remote_handler=dbgp xdebug.remote_host=localhost xdebug.remote_port=9000 xdebug.idekey="netbeans-xdebug" However, nothing happens, there are no information related to xdebug from phpinfo. Also xdebug announce that xdebug have not installed yet (http://xdebug.org/find-binary.php). I am so worried causing too much time for configuration. I got crazy and totally gave up. Anyone have ideas to solve it, I am so appreciated what you help me. Thanks

  • How Moles Isolation framework is implemented?

    - by Buu Nguyen
    Moles is an isolation framework created by Microsoft. A cool feature of Moles is that it can "mock" static/non-virtual methods and sealed classes (which is not possible with frameworks like Moq). Below is the quick demonstration of what Moles can do: Assert.AreNotEqual(new DateTime(2012, 1, 1), DateTime.Now); // MDateTime is part of Moles; the below will "override" DateTime.Now's behavior MDateTime.NowGet = () => new DateTime(2012, 1, 1); Assert.AreEqual(new DateTime(2012, 1, 1), DateTime.Now); Seems like Moles is able to modify the CIL body of things like DateTime.Now at runtime. Since Moles isn't open-source, I'm curious to know which mechanism Moles uses in order to modify methods' CIL at runtime. Can anyone shed any light?

  • ASP.NET Validator Controls Slowing Down Page

    - by Calvin Nguyen
    Hi all, I have an UpdatePanel that has user controls dynamically added to it. There can be a few dozen user controls at times. The page / UpdatePanel slows down big time on each postback as more user controls are added. After some digging, I was surprised to find the cause is the various CompareValidator, CustomValidator, RegularExpressionValidator and RequiredFieldValidator controls that exist on each user control. Dose anyone have suggestions? It strikes me as very peculiar that inclusion of these ASP.NET controls could have such a horrible effect on performance. Thanks, Calvin

  • Unable to display data in a WPF datagrid that has a DataView instance as the items source

    - by Jimmy W
    I am using a DataGrid object from the WPF toolkit. I am binding the DataGrid object to the default view of a DataTable instance as declared in the following code: WeatherGrid.ItemsSource = weatherDataTable.DefaultView; weatherDataTable has three columns. The first column is defined to contain a string data type. The other two columns are defined to contain double data types. When the application exits the function that calls the binding as expressed in the declaration, The DataGrid object displays data for the first column, but not the other columns. When I type the following in the immediate window in the debugger: ((DataRowView)WeatherGrid.Items[0]).Row[1] I get a number, but this doesn't correspond with what is being displayed. Why is only the first column visible, and how can I get all of the data to be visible? I'll leave my XAML definition for the DataGrid object below: <toolkit:DataGrid Margin="12.726,77.71,12,0" Name="WeatherGrid" Height="500" Grid.Row="1" VerticalAlignment="Top" CanUserAddRows="False" CanUserDeleteRows="False" IsReadOnly="True" />

Every time I try to access Memcache within a thread, then I get this error: ApiProxy$CallNotFoundException: The API package 'memcache' or call 'Increment()' was not found I guess that the testing library of GAE SDK tried to mimic the real environment and thus setup the environment for only one thread (the thread that running the test) which cannot be seen by other thread.

  • ASP.NET putting dynamic controls on page in reverse messes up events

    - by Jimmy Geels
    I have this weird problem when putting textboxes on the page in reverse. The whole event system is messed up. Changing one textbox fires TextChange on all textboxes. I can fix this by putting the controls in a list first and then call add while iterating trough the list in reverse. But i just want to know why this fails. Heres some code (.net 2.0) public partial class _Default : Page { protected void Page_Load(object sender, EventArgs e) { InitFields(); } private void InitFields() { int nrFields; //We have a static textbox called nrElements, this determines the number //of fields to initialize if (int.TryParse(nrElements.Text, out nrFields)) { //Put all the dynamic fields on the screen in reverse order foreach(Control t in GetDynamicFields(nrFields)) { //Calling Controls.Add works fine //Calling Controls.AddAt messes up the events //Try changing different textboxes plhFields.Controls.AddAt(0, t); } } } private IEnumerable<Control> GetDynamicFields(int nrFields) { for (int i = 0; i < nrFields; i++) { TextBox txtBox = new TextBox(); txtBox.ID = string.Format("dynTextBox{0}", i.ToString()); txtBox.AutoPostBack = true; txtBox.TextChanged += t_TextChanged; yield return txtBox; } } private void t_TextChanged(object sender, EventArgs e) { TextBox txtBox = sender as TextBox; if (txtBox != null) txtBox.Text = txtBox.Text + "Changed "; } }

    Well, I'm trying to create a newsletter, that will send emails to users in a database. The newsletter itself would draw "events" and other activities from a database. Whats the best way to take that list, and put them in an email? I was thinking about putting them into an html page, then sending an html email, but not all emails support html(like school email). What would your guys recommend? Could you point me to some good resources? Also, this is for a school project, so I cant use any open source type stuff, unfortunately :(

  • .NET regex: Match.nextMatch() never returns

    - by Jimmy
    I have a regex that seems to have worked fine for the past year or so, and all of a sudden today with a new slightly different text to match against, Match.nextMatch() never returns. I'm no regex expert and I'm sure the regex can be optimized, but previous data sets weren't much more complex than what I've tried today. Furthermore, the regex works fine against the offending data set in a tool like RegexBuddy; it's only in .net (running in debug in Visual Studio) that it seems to hang. Nevertheless, if anyone can figure out how to tweak the regex to make it work, I'd really appreciate it. This is the regex: <tr>(<td[^>]*><a[^>]*>(?<callOptionTicker>[A-Z]{1,5}\d{6}C\d{8})</a></td>)(<td[^>]*>.*?</td>){6}(<td[^>]*><b><a[^>]*>(?<strikePrice>\d*\.\d*)</a></b></td>)(<td[^>]*><a[^>]*>(?<putOptionTicker>[A-Z]{1,5}\d{6}P\d{8})</a></td>) It's meant to extract put and call option tickers from a Yahoo option chain page (i.e., raw HTML). It works fine for IBM http://finance.yahoo.com/q/os?s=IBM&m=2010-05-21 It doesn't work for SPX options (this is the offending data set) http://finance.yahoo.com/q/os?s=I:SPX.W&m=2010-05
