I began using the "record macro" function but I'm having trouble. I need the macro to copy data column by column and transpose it into a corresponding row, 15 rows apart. There are 100 entries per document. For example; P4 - P23 in document 1 needs to be transposed to M217 - AF217 in document 2. Q4 - Q23 needs to be transposed to M232 - AF 232, up to row 1501.</p> |

Website address is slightly different than fully qualified domain name <p>I have a website that is being configured with SSL, and I am using a self-signed certificate for testing purposes, for now. The machine is running Windows 2008 R2 with IIs 7.5 and Apache Tomcat 5.5. </p> <p>The problem is FireFox is gives the error that the connection is untrusted because it's a self-signed certificate and it also says that the site is using an invalid security certificate. I tried importing the certificate into Firefox, to remedy the situation, and it did not help. However, with IE, exporting the certificate from IIS and importing it into the browser's Trusted Root Certificate Authorities store permitted IE to trust the self-signed certificate.</p> <p>It's important to note that the server's fully qualified domain name is webdev.dev.mysite.com, whereas the website address is webdev.mysite.com and I've had no problems with the site under HTTP.

However you cannot do <code>c = { 3, 5, 6 }</code> afterward, because the braced-init-lists may only be initializers for new variables, not operands to built-in expressions. (In a declaration, the <code>=</code> sign is just a notation for initialization. It is not the usual operator. Braced lists are specifically allowed by the grammar for assignment operators, but this usage is only valid with function overloading, which causes the list to initialize a new variable: the function parameter.)</p> <p>The answer to your final question is that there's no way to write the necessary <code>operator =</code> overload for "naked" arrays, because it must be a member function.

Input for any system would be appreciated, however.</p> <hr> <p>Just so people know some useful stuff pertaining to this, here's some code that may be difficult to come up with without some research. This doesn't allow user-input, but it does keep the window open. The code is specifically for Linux:</p> <pre><code>import subprocess, shlex; myFilePathString="/home/asdf asdf/file.py"; params=shlex.split('x-terminal-emulator -e bash -c "python3 \''+myFilePathString+'\'; echo \'(Press any key to exit the terminal emulator.)\'; read -n 1 -s"'); subprocess.call(params); </code></pre> <p>To open it with the Python interpreter running afterward, which is about as good, if not better than what I'm looking for, try this:</p> <pre><code>import subprocess, shlex; myFilePathString="/home/asdf asdf/file.py"; params=shlex.split('x-terminal-emulator -e bash -c "python3 -i \''+myFilePathString+'\'"'); subprocess.call(params); </code></pre> <p>I say these examples may take some time to come up with because passing parameters to bash, which is being opened within another command can be problematic without taking a few steps. Plus, you need to know to use to quotes in the right places, or else, for example, if there's a space in your file path, then you'll have problems and might not know why.</p> <p>EDIT: For clarity (and part of the answer), I found out that there's a standard way to do this in Windows:</p> <pre><code>cmd /K [whatever your commands are] </code></pre> <p>So, if you don't know what I mean try that and see what happens. Here's the URL where I found the information: <a href="http://ss64.com/nt/cmd.html" rel="nofollow">http://ss64.com/nt/cmd.html</a></p> |
2,481,876 | 0 | <p>The accepted answer here did not work for me. Instead I had to cast the base channel into an IContextChannel, and set the OperationTimeout on that. </p> <p>To do that, I had to create a new file with a partial class, that matched the name of the ServiceReference. In my case the I had a PrintReportsService. Code is below. </p> <pre><code>using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; namespace RecipeManager.PrintReportsService { public partial class PrintReportsClient : System.ServiceModel.ClientBase<RecipeManager.PrintReportsService.PrintReports>, RecipeManager.PrintReportsService.PrintReports { public void SetOperationTimeout(TimeSpan timeout) { ((System.ServiceModel.IContextChannel)base.Channel).OperationTimeout = timeout; } } } </code></pre> <p>Then when I create the client, I do the following:</p> <pre><code> PrintReportsService.PrintReportsClient client = new RecipeManager.PrintReportsService.PrintReportsClient(); client.SetOperationTimeout(new TimeSpan(0, 4, 0)); </code></pre> <p>That did it for me!

4,600,750 | 0 | Idiomatic usage of filter, map, build-list and local functions in Racket/Scheme? <p>I'm working through <a href="http://htdp.org/2003-09-26/Book/curriculum-Z-H-27.html#node_sec_21.2" rel="nofollow">Exercise 21.2.3</a> of HtDP on my own and was wondering if this is idiomatic usage of the various functions. This is what I have so far:</p> <pre><code>(define-struct ir (name price)) (define list-of-toys (list (make-ir 'doll 10) (make-ir 'robot 15) (make-ir 'ty 21) (make-ir 'cube 9))) ;; helper function (define (price< p toy) (cond [(< (ir-price toy) p) toy] [else empty])) (define (eliminate-exp ua lot) (cond [(empty? lot) empty] [else (filter ir? (map price< (build-list (length lot) (local ((define (f x) ua)) f)) lot))])) </code></pre> <p>To my novice eyes, that seems pretty ugly because I have to define a local function to get <code>build-list</code> to work, since <code>map</code> requires two lists of equal length. Can this be improved for readability? Thank you.</p> |

If you examine the image in Preview, what you want is the number of pixels per character to be say 16x16 or 32x32, not 256x256.

This is working fine for viewing the initial list, editing an item and deleting an item. I am however having a problem with the insertion of a new item.</p> <p>Specifically, within my EditItemTemplate and InsertItemTemplate I have a DropDownList (well, actually it is a custom control derived from DropDownList but for the purposes of this question it is a DropDownList). The control is defined within the markup as follows...</p> <pre><code><agp:ClientStatusDropDownList ID="ClientStatusID" runat="server" SelectedValue="<%#: BindItem.ClientStatusID %>" /> </code></pre> <p>Within the EditItemTemplate, this is fine however within the InsertItemTemplate this generates an error upon running the page: <em>Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.</em></p> <p>As such, I removed the section <code>SelectedValue="<%#: BindItem.ClientStatusID %>"</code> from the InsertItemTemplate and tried again. This time no error message, however when the <code>ListView.InsertMethod</code> is called, the ClientStatusID property on the model is not set to the value of the DropDownList (whereas the rest of the properties are set correctly).</p> <p>The ListView.InsertMethod:</p> <pre><code>public void ListView_InsertMethod(int ID) { Model model = this.DbContext.Models.Create(); if (this.TryUpdateModel(model)) { this.DbContext.SaveChanges(); this.ListView.DataBind(); } } </code></pre> <p>The Model class:</p> <pre><code>public class Model{ public Int32 ID { get; set; } public String Description { get; set; } public Boolean IsScheduleFollowUp { get; set; } public Nullable<Int32> ClientStatusID { get; set; } } </code></pre> <p>The EditItemTemplate:</p> <pre><code><EditItemTemplate> <tr> <td> <asp:TextBox ID="Description" runat="server" Text="<%#: BindItem.Description %>" /> </td> <td> <asp:CheckBox ID="IsScheduleFollowUp" runat="server" Checked="<%# BindItem.IsScheduleFollowUp %>" /> </td> <td> <agp:ClientStatusDropDownList ID="ClientStatusID" runat="server" SelectedValue="<%#: BindItem.ClientStatusID %>" /> </td> <td> <asp:Button ID="Update" runat="server" ClientIDMode="Static" CommandName="Update" Text="Update" /> <asp:Button ID="Cancel" runat="server" ClientIDMode="Static" CommandName="Cancel" Text="Cancel" /> </td> </tr> </EditItemTemplate> </code></pre> <p>The InsertItemTemplate:</p> <pre><code><InsertItemTemplate> <tr> <td> <asp:TextBox ID="Description" runat="server" Text="<%#: BindItem.Description %>" /> </td> <td> <asp:CheckBox ID="IsScheduleFollowUp" runat="server" Checked="<%# BindItem.IsScheduleFollowUp %>" /> </td> <td> <agp:ClientStatusDropDownList ID="ClientStatusID" runat="server" /> </td> <td> <asp:Button ID="Insert" runat="server" ClientIDMode="Static" CommandName="Insert" Text="Add" /> </td> </tr> </InsertItemTemplate> </code></pre> <p>I had originally thought that it was the ID of the control that was used to determine the property on the model that the value would be passed to (i.e. where the TextBox was called "Description", the value would be passed to the "Description" property of the model). Clearly this is not the case and it is instead controlled by the "<%# BindItem.Description %>", however as you can see from the rest of this question I am unable to use this syntax in the "InsertItemTemplate". I cannot believe that the DropDownList is not supported in this scenario, but I cannot find any examples of a DropDownList being used with the 4.5 model bindings using Google or Bing (in fact, there are very few examples of the new model binding in ASP.NET 4.5 using anything other than a couple of TextBox controls).</p> <p>Can anybody shed any further light on the issue (and preferably tell me what needs to be done)?</p> <p>Other questions on SO that I have looked at...</p> <ul> <li><a href="http://stackoverflow.com/questions/470315/binding-a-dropdownlist-in-listview-insertitemtemplate-throwing-an-error">Binding a DropDownList in ListView InsertItemTemplate throwing an error</a></li> <li><a href="http://stackoverflow.com/questions/2184757/asp-net-listview-with-identical-markup-in-edititemtemplate-and-insertitemtemplat">ASP.NET ListView with identical markup in EditItemTemplate and InsertItemTemplate</a></li> <li><a href="http://stackoverflow.com/questions/2265852/bind-selectedvalue-of-asp-net-dropdownlist-to-custom-object">Bind SelectedValue of ASP.net DropDownList to custom object</a></li> <li><a href="http://stackoverflow.com/questions/3785021/databinding-to-asp-net-dropdownlist-list-in-listview">Databinding to ASP.NET DropDownList list in ListView</a></li> </ul> <p>All of these use the older style binding methods and not the new methods in 4.5</p> <p>Thanks.</p> |

Any clues as to why that is?</p> <p>Note: I am not getting any javascript errors in Firefox's error console in the local context.</p> <p><strong>UPDATE</strong>: I tried grabbing the HTML from <a href="http://fiddle.jshell.net/ambiguous/ZEx6M/1/show/light" rel="nofollow">fiddle.jshell.net/ambiguous/ZEx6M/1/show/light</a> to a local file and loading that local file in Chromium browser and I got the following errors in the javascript console:</p> <ul> <li><code>GET file:///css/normalize.css undefined (undefined) /css/normalize.css</code></li> <li><code>GET file:///css/result-light.css undefined (undefined) /css/result-light.css</code></li> <li><code>Resource interpreted as Script but transferred with MIME type application/empty jquery.scrollTo-1.4.2.js:-1</code></li> <li><code>Resource interpreted as Script but transferred with MIME type text/plain jquery.viewport.js:-1</code></li> </ul> <p>I can get rid of these javascript errors by downloading the files and modifying the <code><script></code> tags, but it doesn't solve the problem. The page still scrolls down to the very bottom. Also these errors appear even in the working (jsFiddle) version.</p> <p>I also tried the same process in Konqueror. Result: the script does absolutely nothing.</p> |

465,467 | 0 | <p>I don't believe it's possible to achieve what you'd like here. From the comments in your code it looks like you are attempting to capture the name of the property which did the assignment in MethodThatTakesExpression. This requires an expression tree lambda expression which captures the contexnt of the property access. </p> <p>At the point you pass a delegate into MethodThatTakesDelegate this context is lost. Delegates only store a method address not any context about the method information. Once this conversion is made it's not possible to get it back. </p> <p>An example of why this is not possible is that there might not even be a named method backing a delegate. It's possible to use ReflectionEmit to generate a method which has no name whatsoever and only exists in memory. It is possible though to assign this out to a Func object. </p> |

3,883,227 | 0 | <p>There are several problems you need to address — both in your code and both in your current knowledge :-) Start with this:</p> <ol> <li><p>Read a few articles about ASP.NET's page life-cycle, so you become more familiar with what to do in each life-cycle event handler (<code>OnInit</code>, <code>OnLoad</code>, …). Good starting point might be this <a href="http://msdn.microsoft.com/en-us/library/ms178472.aspx" rel="nofollow">MSDN overview</a>. However, google for “ASP.NET page life cycle” and read a few other articles and examples as well.</p> <p>Also, you will need to get familiar with the request-response nature of ASP.NET page processing. In the beginning, bear in mind that when the user hits some 'Submit' button which in turn causes an HTTP POST request to occur, you are responsible to creating the page's control tree to match its structure, IDs, etc. as they were in the previous request. Otherwise ASP.NET doesn't know how in which controls to bind the data the user filled-in.</p></li> <li><p>Near the line tagged <code>//Lost and confused here :/</code> you are creating a new control and immediately querying it for the 'results' (which I expect to be values of some edit boxes within it). This cannot work, because it's most probably too early for the form to have the data received from the <code>Page</code> object that drives the request processing.</p></li> <li><p>Your <code>Results</code> property is poorly designed. First, you shouldn't be using properties that actually 'generate' data in such a way they can change without notice. Properties shall be used as “smart fields”, otherwise you end up with less manageable and less readable code. Second, the setter you left there like “set;” causes any value assigned into the property to be actually lost, because there's no way to retrieve it. While in some rare cases this behavior may be intentional, in your case I guess it's just an error.</p></li> </ol> <p>So, while you can currently leave behind any “good OOP way” to approach your problem, you certainly should get more familiar with the page life-cycle. Understanding it really requires some thinking about the principles how ASP.NET web applications are supposed to work, but I'm sure it will provide you with the kick forward you actually need.</p> <p><strong>UPDATE:</strong> In respect to Tony's code (see comments) the following shall be done to move the code forward:</p> <ol> <li><p>The list of form data in the <code>requestForm</code> property shall have tuple of [form ASCX path, control ID, the actual <code>RequestForm</code> data class]</p></li> <li><p><code>GatherForms</code> shall be called only when the page is initially loaded (i.e. <code>if (Page.IsPostBack)</code>) and it shall fill <code>requestForm</code> with the respective tuples for available ASCX forms.</p></li> <li><p>Both <code>chklApplications</code> and wizard steps shall be created in <code>LoadForms</code> on the basis of <code>requestForm</code>'s content.</p></li> <li><p>When results are to be gathered, the ID stored in the respective <code>requestForm</code> entry can be used to look-up the actual user control.</p></li> </ol> |
