• Dynamically resizing CMFCPropertySheet with PropSheetLook_OneNoteTabs style

  - by Ryan

  Hi everybody, I'm trying to resize dynamically a CMFCPropertySheet to add a custom control at the bottom of each page. As all Property Pages are not of the same height, I have a mechanism to increase the size if necessary. For this, I have overridden the OnActivatePage method and by using SetWindowPos, I can resize the sheet, first, then the tab control, then the page and finally I can move the OK/Cancel/Help buttons. It works fine with PropSheetLook_OutlookBar and PropSheetLook_Tabs styles but not with PropSheetLook_OneNoteTabs style. The page (or the tab) is not correctly resized (the lighter grey color of the page does not fill the sheet. OneNote style Outlook style Any idea? A MFC Feature Pack bug?

• Creating an inline function in a jsp?

  - by user246114

  Hi, I'm coming from (some limited) PHP experience, in which you can just declare functions in-line. I'm trying to the same thing with a JSP but not working. Trying something like: <%! private void generateSomething() { %> <p> Hello there! </p> <% } %> <% generateSomething(); %> is something like that possible? Basically I have a jsp that can generate a 3 different pages, and I wanted to put these each in a separate method. I have seen a few posts saying this is not a good idea, and to separate the presentation stuff, which is fine, I just want to see this in action, if possible, now I'm just curious, Thanks

• Synchronization requirements for FileStream.(Begin/End)(Read/Write)

  - by Doug McClean

  Is the following pattern of multi-threaded calls acceptable to a .Net FileStream? Several threads calling a method like this: ulong offset = whatever; // different for each thread byte[] buffer = new byte[8192]; object state = someState; // unique for each call, hence also for each thread lock(theFile) { theFile.Seek(whatever, SeekOrigin.Begin); IAsyncResult result = theFile.BeginRead(buffer, 0, 8192, AcceptResults, state); } if(result.CompletedSynchronously) { // is it required for us to call AcceptResults ourselves in this case? // or did BeginRead already call it for us, on this thread or another? } Where AcceptResults is: void AcceptResults(IAsyncResult result) { lock(theFile) { int bytesRead = theFile.EndRead(result); // if we guarantee that the offset of the original call was at least 8192 bytes from // the end of the file, and thus all 8192 bytes exist, can the FileStream read still // actually read fewer bytes than that? // either: if(bytesRead != 8192) { Panic("Page read borked"); } // or: // issue a new call to begin read, moving the offsets into the FileStream and // the buffer, and decreasing the requested size of the read to whatever remains of the buffer } } I'm confused because the documentation seems unclear to me. For example, the FileStream class says: Any public static members of this type are thread safe. Any instance members are not guaranteed to be thread safe. But the documentation for BeginRead seems to contemplate having multiple read requests in flight: Multiple simultaneous asynchronous requests render the request completion order uncertain. Are multiple reads permitted to be in flight or not? Writes? Is this the appropriate way to secure the location of the Position of the stream between the call to Seek and the call to BeginRead? Or does that lock need to be held all the way to EndRead, hence only one read or write in flight at a time? I understand that the callback will occur on a different thread, and my handling of state, buffer handle that in a way that would permit multiple in flight reads. Further, does anyone know where in the documentation to find the answers to these questions? Or an article written by someone in the know? I've been searching and can't find anything. Relevant documentation: FileStream class Seek method BeginRead method EndRead IAsyncResult interface

• WebBrowser control not submitting form, IE 7 works

  - by Joel Cunningham

  We are using a WebBrowser control in our win forms application which is running in terminal services. IE 7 is the browser that is installed for the session. We are using WebForms to generate the web pages. If we try and submit a web page in the WebBrowser control it does not work. The submit button does not push down. If we try and submit a web page in IE 7 that is installed on the same machine it works as expected. This is only an issue for one person. The WebBrowser control is working for other users. Any thoughts on how I can debug why the submit button is not submitting for the WebBrowser control? Thanks in advance.

• Wider than expected margins with CGContextDrawPDFPage

  - by skantner

  I'm rendering PDF pages on iPhone using the code below. It works, but the margins seem much wider than when I view the same PDF using a Acrobat Reader or the Mac's Preview, and that consequently scales the content down much smaller than it otherwise would be. Is my code actually causing this behavior? CGContextSetStrokeColorWithColor(context, backgroundColor.CGColor); CGContextSetFillColorWithColor(context,backgroundColor.CGColor); CGContextSetLineWidth(context, 2.0); CGContextAddRect(context, CGRectMake(0.0,0.0, self.bounds.size.width, self.bounds.size.height)); CGContextDrawPath(context, kCGPathFillStroke); CGContextTranslateCTM(context, 0.0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); CGPDFPageRef page = CGPDFDocumentGetPage(myPDF, (size_t) pageNum); CGContextSaveGState(context); CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFMediaBox, self.bounds, 0, true); CGContextConcatCTM(context, pdfTransform); CGContextDrawPDFPage(context, page); CGContextRestoreGState(context);

• ASP.NET 3.5 Routing?

  - by Maushu

  I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

• java.security.AccessControlException: access denied using Java Web Start

  - by killiancomputers

  I am having some issues with accessing files using JWS (Java Web Start). The program adds a new label and image. The program runs fine on my local computer but gives me pages of errors when I run the program on my remote server using JWS. Here's a sample of the error: Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.io.FilePermission add2.png read) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) This occurs even after making sure the images have read access. Ideas?

• Rx framework: How to wait for an event to be triggered in silverlight test

  - by user324255

  Hi, I have a ViewModel that starts loading the Model async in the constructor, and triggers an event when the Model is loaded. I got a test working with the silverlight unit test framework, like this : bool done = false; [TestMethod] [Asynchronous] public void Test_NoCustomerSelected() { ProjectListViewModel viewModel = null; EnqueueCallback(() => viewModel = new ProjectListViewModel()); EnqueueCallback(() => viewModel.ModelLoaded += new EventHandler<EventArgs>(viewModel_ModelLoaded)); EnqueueConditional(() => done); EnqueueCallback(() => Assert.IsNotNull(viewModel.FilteredProjectList)); EnqueueCallback(() => Assert.AreEqual(4, viewModel.FilteredProjectList.Count)); EnqueueTestComplete(); } void viewModel_ModelLoaded(object sender, EventArgs e) { done = true; } But I'm beginning playing with Rx Framework, and trying to get my test to work, but so far I have no luck. Here's 2 attempts : public void Test_NoCustomerSelected2() { ProjectListViewModel viewModel = null; viewModel = new ProjectListViewModel(eventAggregatorMock.Object, moduleManagerMock.Object); IObservable<IEvent<EventArgs>> eventAsObservable = Observable.FromEvent<EventArgs>( ev => viewModel.ModelLoaded += ev, ev => viewModel.ModelLoaded -= ev); eventAsObservable.Subscribe(args => viewModel_ModelLoaded(args.Sender, args.EventArgs)); eventAsObservable.First(); Assert.IsNotNull(viewModel.Model); Assert.AreEqual(4, viewModel.Model.Count); } [TestMethod] public void Test_NoCustomerSelected3() { ProjectListViewModel viewModel = null; var o = Observable.Start(() => viewModel = new ProjectListViewModel(eventAggregatorMock.Object, moduleManagerMock.Object)); IObservable<IEvent<EventArgs>> eventAsObservable = Observable.FromEvent<EventArgs>( ev => viewModel.ModelLoaded += ev, ev => viewModel.ModelLoaded -= ev); o.TakeUntil(eventAsObservable) .First(); Assert.IsNotNull(viewModel.Model); Assert.AreEqual(4, viewModel.Model.Count); } The first test goes in waiting forever, the second doesn't work because the viewModel is null when it does the FromEvent. Anyone has a clue on how to do this properly?

• Configuring asp.net web applications. Best practices

  - by Andrew Florko

  Hello everybody, There is a lot of configurable information for a web-site: UI messages Number of records used in pagination & other UI parameters Cache duration for web-pages & timeouts Route maps & site structure ... There are many approaches to store all this information also: AppSettings (web.config) Custom sections (web.config) External xml/text files referred from web.config Internal static class(es) of constants Database table(s) ... What approaches do you usually choose for your tasks & what approaches do you find unsuitable? Thank you in advance!

• Why is my CalendarExtender getting overlapped when rendered?

  - by Dillie-O

  I'm working on a .NET web application and I'm using a CalendarExtender control within it to have the user specify a date. For some reason, when I click the icon to display the calendar, the background seems to be transparent, shown below: I'm using the extender on other pages and do not run into this issue. I'm not sure if it is worth mentioning, but the calendar is nested within a panel that has a rounded corner extender attached to it, as well as the panel below it (where the "From" is overlapping). Within that panel, I do have a div layout setup to create two columns. EDIT: The other thing to note here is that the section that has the name and "placeholders" for nickname are all ASP.NET label controls, if that matters.

• Learning Linux screencasts

  - by Dmitriy Nagirnyak

  Hi, I am trying to get started with Linux. There are number of books (many of which are just man pages), some of them provide good overview so I can dig deeper online then. What I would like is to find number of screencasts that would cover basics of Linux commands, server administration, commonly performed tasks etc (no GUI, only terminal). I want to watch the screencasts to "get it quicker" and then use a book or online resources to "dig it deeper". Any recommendations? Thanks, Dmitriy.

• Windows Mobile Silverlight?

  - by eidylon

  Is it possible to develop Silverlight apps to run on WinMo devices? I see all around searching on the web - in articles from 2008 and 2009 - that they were adding Silverlight support in WinMo 6.1, for example: Internet Explorer Mobile The new version of Internet Explorer Mobile adds the ability to easily view full-screen Web pages and multimedia on the Web with a smartphone. Microsoft's press release states the new version takes advantage of "Internet Explorer 6 technologies" and supports industry standards such as H.264, Adobe Flash and Microsoft Silverlight. The update will be available to mobile phone partners in the third quarter of 2008, with the first Windows Mobile phones using the new version expected to be available by the end of 2008. But I have found an SL app supposedly geared for mobile devices (as much as I hate weatherbug), but when i try going there in PIE on my WinMo 6.1 device, it shows me the little "get silverlight" image button, but clicking it doesn't do anything. So, what is the story? Is SL/WinMo development possible, or ?

• iTextSharp and VBnet question about headers

  - by bpSz

  Hello! I'm wondering how can I put a header into my pdf file, cause i've tried the tutorials from here: http://itextsharp.sourceforge.net/tutorial/ch04.html And it have not worked. Ive done this: Dim head As New HeaderFooter(New Phrase("This is page: "), False) head.Border = Rectangle.NO_BORDER document.Header = head But VS2008 says that HeaderFooter it's not defined (line 1), and Footer it's not a member of "iTextSharp.text.document" (line 3). I've already included the imports at the begining of my code and i don't have any other problems with the iTextsharps (i mean that it is working apart of the header problem): Imports iTextSharp.text Imports iTextSharp.text.pdf Imports System.Data.SQLite Imports System.IO So please, can anyone explain to me how can i set a header for my pages? Regards

• Customizing Number of Page Links Rendered With will_paginate?

  - by Moe

  I'm using the will_paginate gem for my Rails project and it's working beautifully. Unfortunately, on paginated result sets with a larger number of pages, the link section is too wide. Instead of: « Previous 1 2 … 5 6 7 8 9 10 11 12 13 … 18 19 Next » I would like to show: « Previous 1 2 … 5 6 7 8 9 … 18 19 Next » How can I reduce the number of page links being rendered? I looked at the will_paginate docs on github but couldn't find a solution. Thanks! Moe

• Hide header and footer when printing from Internet Explorer using Javascript or CSS

  - by molasses

  When I print a webpage from Internet Explorer it will automatically add a header and footer including the website title, URL, date, and page number. Is it possible to hide the header and footer programatically using Javascript or CSS? Requirements: works in IE 6 (no other browser support necessary as its for an Intranet) may use ActiveX, Java Applet, Javascript, CSS preferably not something that the user needs to install (eg. http://www.meadroid.com/scriptx). feel free to list other third party available plug-ins though as I think this may be the only option don't require the user to manually update their browser settings don't render the pages as PDF or Word document or any other format don't write to the registry (security prevents this) Thanks

• Create hyperlink to some text in NSTextView

  - by regulus6633

  I can create a hyperlink to some url in an NSTextView using the "Link Panel". Or I can add a link manually using the NSLinkAttributeName attribute of NSAttributedString. I don't want to make a hyperlink to some external url though, I want to be able to create a hyperlink to some text within the NSTextView. Do you know how in Pages you can set some text as a Bookmark, and then you can make a hyperlink to that bookmark? Any ideas or examples of how to go about that?

• What is all this stuff in the CKEditor folder?

  - by Ashley Ward

  A while ago I downloaded the latest version (3.1) of the CKEditor text editor. The directory name was ckeditor and I deleted the ckeditor/_source and ckeditor/_samples sub-directories, then I referenced the ckeditor.js file in my html pages, like so : <script type="text/javascript" src="ckeditor/ckeditor.js"></script> this works well. To make config changes, I have been modifying the ckeditor/config.js file. However, as of late, I have been reading various web resources that say 'do not delete the _source' folder and other such ominous messages. What is this _source folder? What is all the stuff at the root of the ckeditor folder? and, What is safe to remove from the folder?

• C++ How to deep copy a struct with unknown datatype?

  - by Ewald Peters

  hi, i have a "data provider" which stores its output in a struct of a certain type, for instance struct DATA_TYPE1{ std::string data_string; }; then this struct has to be casted into a general datatype, i thought about void * or char *, because the "intermediate" object that copies and stores it in its binary tree should be able to store many different types of such struct data. struct BINARY_TREE_ENTRY{ void * DATA; struct BINARY_TREE_ENTRY * next; }; this void * is then later taken by another object that casts the void * back into the (struct DATA_TYPE1 *) to get the original data. so the sender and the receiver know about the datatype DATA_TYPE1 but not the copying object inbetween. but how can the intermidiate object deep copy the contents of the different structs, when it doesn't know the datatype, only void * and it has no method to copy the real contents; dynamic_cast doesn't work for void *; the "intermediate" object should do something like: void store_data(void * CASTED_DATA_STRUCT){ void * DATA_COPY = create_a_deepcopy_of(CASTED_DATA_STRUCT); push_into_bintree(DATA_COPY); } a simple solution would be that the sending object doesn't delete the sent data struct, til the receiving object got it, but the sending objects are dynamically created and deleted, before the receiver got the data from the intermediate object, for asynchronous communication, therefore i want to copy it. instead of converting it to void * i also tried converting to a superclass pointer of which the intermediate copying object knows about, and which is inherited by all the different datatypes of the structs: struct DATA_BASE_OBJECT{ public: DATA_BASE_OBJECT(){} DATA_BASE_OBJECT(DATA_BASE_OBJECT * old_ptr){ std::cout << "this should be automatically overridden!" << std::endl; } virtual ~DATA_BASE_OBJECT(){} }; struct DATA_TYPE1 : public DATA_BASE_OBJECT { public: string str; DATA_TYPE1(){} ~DATA_TYPE1(){} DATA_TYPE1(DATA_TYPE1 * old_ptr){ str = old_ptr->str; } }; and the corresponding binary tree entry would then be: struct BINARY_TREE_ENTRY{ struct DATA_BASE_OBJECT * DATA; struct BINARY_TREE_ENTRY * next; }; and to then copy the unknown datatype, i tried in the class that just gets the unknown datatype as a struct DATA_BASE_OBJECT * (before it was the void *): void * copy_data(DATA_BASE_OBJECT * data_that_i_get_in_the_sub_struct){ struct DATA_BASE_OBJECT * copy_sub = new DATA_BASE_OBJECT(data_that_i_get_in_the_sub_struct); push_into_bintree(copy_sub); } i then added a copy constructor to the DATA_BASE_OBJECT, but if the struct DATA_TYPE1 is first casted to a DATA_BASE_OBJECT and then copied, the included sub object DATA_TYPE1 is not also copied. i then thought what about finding out the size of the actual object to copy and then just memcopy it, but the bytes are not stored in one row and how do i find out the real size in memory of the struct DATA_TYPE1 which holds a std::string? Which other c++ methods are available to deepcopy an unknown datatype (and to maybe get the datatype information somehow else during runtime) thanks Ewald

• iphone: UIwebview curl effect

  - by eshalev

  Hello, I would like to make a standard view container which will give me the curl animation effect on multiple views. Something like uiscrollview and paging, only with a different animation(curl). I will be using UIwebviews as my separate pages. The problem: I do not know how to trap swipes in UIwebviews, But I see that UIscrollview implments this (swiping a uiwebview in a uiscrollview will bring me to the next view). I am therefore assuming that the implmentation of UIscrollview is trapping UIwebview swipes. How can i achieve the same functionality? I also need the UIWebview to keep functioning (as when embedding it in a uiscrollview)

• How can I create a hybrid Silverlight and aspx application

  - by PilotBob

  Here is my scenerio.. We have an ASP.Net 2.x web site. We want to migrate it to Silverlight full frame application. However, there is no way we can go away in a corner and redo every web page in SL right off the bat. What I would like to do is build the chrome of the app (main page, dashboard, login, common system/config screens, main menu) in SL and be able to open existing .aspx pages in the main content SL frame. From what I see there is no way to do this. I thought the Webbrowser control in SL4 would be the answer, but apparently that only works if your app is run out of browser. So, what is my best recourse? It seems like I will have to create some type of .aspx page that hosts the .XAP and pass in the page I want it to load? How would you gurus approach this?

• Easiest way to open chm files programmatically?

  - by Adrian Grigore

  Hi, I have a legacy 32-bit application written in Borland's C++ Builder. I need to show specific pages from within a HtmlHelp file programmatically. Until now I've been doing this via HtmlHelp.ocx, but this does not work on x64 versions of Windows Vista / Windows7 as described in this thread. I can't compile the application as 64-bit executable. Therefore the only workaround I have found so far is to create a 32-bit component implementing a COM object which loads and calls into the 32-bit DLL, and exposes the 32-bit DLL interface as a COM interface. That sounds far too complicated just to display a chml file with a specific topic. There must be something else. But what is it?

• Struts 1 - struts-taglib.jar is not being found by my web application

  I am using Struts-1. I have developed a struts-based web application. I am using struts tags in my JSP pages supplied in struts-taglib.jar by inserting the following lines in the JSP file: <%@ taglib prefix="html" uri="http://struts.apache.org/tags-html" %> <%@ taglib prefix="logic" uri="http://struts.apache.org/tags-logic" %> <%@ taglib prefix="bean" uri="http://struts.apache.org/tags-bean" %> Now the application is working fine when I run it on my localsystem but when I deploy it on a server, it shows the following exception: org.apache.jasper.JasperException: The absolute uri: http://struts.apache.org/tags-html cannot be resolved in either web.xml or the jar files deployed with this application From the above exception, it seems that the application hasn't found the struts-taglib.jar file. But I have put the struts-taglib.jar in /WEB-INF/lib directory. Then where is the problem?
