• SSRS 2008 printing single page renders different for print

  - by user270437

  I have a problem with SSRS 2008 reports rendering differently on the reporting server than the way it renders when you print the report. I’m trying to figure out to print a single page and have the print show that same records as I see on the report on the screen. As a test, I created a simple report with no headers or footers and just added a Tablix table to display the records (no groupings). My data set for this test displays 2 ¼ pages of records when I deploy it to our reporting services server and run it. If I click the print Icon and preview the report is 2 ¾ pages. I haven’t found anything searching on this so it makes me think it is something simple I’m missing. A basically want the report to render the same records on each page in Report Manager as it does when it prints, how do I accomplish this? (In response to answer posted by Chris)…If that is the case then it is disappointing. Customers are accustomed to WYSIWYG and will have a hard time understanding that, I imagine we will be getting a lot of support calls. This still leaves an issue. I tried using print preview and could not find any way to single out a page. If I select a page up front to print, or preview it renders different so I get different records. And if I preview the entire document, I can only print the entire document. You mentioned the Excel render; we have customers that will want that also. The problem I have found with Excel exports is that even a basic report winds up merging some cells and that messes up sorting. I’m going to try your tip about grouping to see if I can get a clean export to a page. It would have been nice if they would have created a property for certain controls like the tablix table called “ExcelSheet”. Then all you would have to do is give it a name and it would create a new sheet for each control with a name, the name becoming the sheet title. Thanks for the information you supplied it is very useful as I’m new to SSRS. If you know how I can Preview in print render and select individual pages to print from the render let me know. Update 02/19/2010 After testing this more I now realize it is just a bad design of Report managers print driver or a limitation because it is server based. The options work differently than Windows apps drivers, But I did find a work around. Here is the test I performed comparing Excel to Report Manager. I bring up a report that will render more than 1 page when printed. I then export to Excel, in Excel I select print preview. I can navigate the pages in preview and then select a single page like page 3. I can then print just page 3 without leaving print preview and it prints just like it rendered. I cannot do this using print in report manager. If I select print preview in report manager then try to print while in preview it always prints the entire document. However if I close out of print preview, I can then select page 3 and print it as rendered. It is just one additional step once you know what to do, but it took some time to figure it out.

• CREATE VIEW called multiple times not creating all views

  - by theninepoundhammer

  Noticing strange behavior in SQL 2005, both Express and Enterprise Edition: In my code I need to loop through a series of values (about five in a row), and for each value, I need to insert the value into a table and dynamically create a new view using that value as part of the where clause and the name of the view. The code runs pretty quickly, but what I'm noticing is that all the values are inserted into the table correctly but only the LAST view is being created. Every time. For example, if the values I'm using are X1, X2, X3, X4, and X5, I'll run the process, open up Mgmt Studio, and see five rows in the table with the correct five values, but only one view named MyView_x5 that has the correct WHERE clause. At first, I had this loop in an SSIS package as part of a larger data flow. When I started noticing this behavior, I created a stored proc that would create the CREATE VIEW statement dynamically after the insert and called EXECUTE to create the view. Same result. Finally, I created some C# code using the Enterprise Library DAAB, and did the insert and CREATE VIEW statements from my DLL. Same result every time. Most recently, I turned on Profiler while running against the Enterprise Edition and was able to verify that the Batch Started and Batch Completed events were being fired off for each instance of the view. However, like I said, only the last view is actually being created. Does anyone have any idea why this might be happening? Or any suggestions about what else to check or profile? I've profiled for error messages, exceptions, etc. but don't see any in my trace file. My express edition is 9.00.1399.06. Not sure about the Enterprise edition but think it is SP2.

Please try again later.** This has happened repeatedly for two days since I started trying to implement it. Not a very helpful error message. Any idea what might cause it or how to narrow down the problem?

• Enterprise integration of disparate systems

  - by Chris Latta

  We're about to embark on a fairly large integration effort to kill off a bunch of Access and Sql Server databases and get everything into one coherent enterprise system. There are also a number of other systems (accounting, CRM, payroll, MS Exchange) that hold critical data that we need to integrate (use for data validation in other systems), report on and otherwise expose. It is likely that some of these systems will change in the next few years, so we need to isolate our systems to be ready for change. Ideally we would be able to expose our forms in a consistent manner across as many of our our systems as possible without having to re-develop them for each system. We are currently targeting SharePoint (2007 and soon 2010), Office (2007 and soon 2010 - Word, Excel, PowerPoint and Outlook), Reporting Services, .Net console applications, .Net Windows applications, shell extensions, and with the possibility of exposing some functionality on mobile devices (BlackBerries currently, maybe iPhones later) and via our website. We're moving development to Visual Studio 2010 (from 2005) ahead of migrating to SharePoint 2010 and Office 2010. Given that most of our development is presently targeted to the .Net framework (mostly in C#) it seems logical to stick with this unless there is some compelling reason to switch frameworks/platform for some aspects. We're thinking of your standard Database-Data Integration layer-Business Objects Layer-Web Services (or REST) layer-Client Application plus doing our own client application with WPF (or something else?) forms that can also be exposed in the MS systems (SharePoint, Office, Windows). So, we don't want much, just everything :) Basically we need to isolate ourselves from database and systems changes, create an API that can be used throughout our systems and then make this functionality available in our client applications. I'm very keen to get pointers from anyone who has tips on how to pull this off. Should we look at the Enterprise Library as a place to start? Is REST with ASP.Net MVC2 a better solution than Web Services for a system like this? Will WPF deliver forms re-use or is there something better?

• Serializing a class containing a custom class

  - by Netfangled

  I want to serialize an object as xml that contains other custom classes. From what I understand (I've been reading MSDN and SO mostly), the XmlSerializer doesn't take this into account. This is the line that's confusing me: XML serialization serializes only the public fields and property values of an object into an XML stream. XML serialization does not include type information. For example, if you have a Book object that exists in the Library namespace, there is no guarantee that it will be deserialized into an object of the same type. Taken from MSDN, here For example, I want to serialize an object of type Order, but it contains a list of Products, and each one contains an object of type Category: class Order { List<Product> products; } class Product { Category type; } class Category { string name; string description; } And I want my Order object to be serialized like so: <Order> <Product> <Category Name=""> <Description></Description> </Category> </Product> <Product> <Category Name=""> <Description></Description> </Category> </Product> <Order> Does the XmlSerializer already do this? If not, is there another class that does or do I have to define the serialization process myself?

• Void* array casting to float, int32, int16, etc.

  - by Griffin

  Hey guys, I've got an array of PCM data, it could be 16 bit, 24 bit packed, 32 bit, etc.. It could be signed, or unsigned, and it could be 32 or 64 bit floating point. It is currently stored as a "void**" matrix, indexed by channel, then by frame. The goal is to allow my library to take in any PCM format and buffer it, without requiring manipulation of the data to fit a designated structure. If the A/D converter spits out 24 bit packed arrays of interleaved PCM, I need to accept it gracefully. I also need to support 16 bit non interleaved, as well as any permutation of the above formats. I know the bit depth and other information at runtime, and I'm trying to code efficiently while not duplicating code. What I need is an effective way to cast the matrix, put PCM data into the matrix, and then pull it out later. I can cast the matrix to int32_t, or int16_t for the 32 and 16 bit signed PCM respectively, I'll probably have to store the 24 bit PCM in an int32_t for 32 bit, 8 bit byte systems as well. Can anyone recommend a good way to put data into this array, and pull it out later? I'd like to avoid large sections of code which look like: switch( mFormat ) { case 1: // unsigned 8 bit for( int i = 0; i < mChannels; i++ ) framesArray = (uint8_t*)pcm[i]; break; case 2: // signed 8 bit for( int i = 0; i < mChannels; i++ ) framesArray = (int8_t*)pcm[i]; break; case 3: // unsigned 16 bit ... Limitations: I'm working in C/C++, no templates, no RTTI, no STL. Think embedded. Things get trickier when I have to port this to a DSP with 16 bit bytes. Does anybody have any useful macros they might be willing to share? Thanks, -Griff

• Deployment a web-site on IIS from another program

  - by slo2ols

  Hi, I developed a web-site on ASP.NET 3.5 SP1 platform. And additional I have 2 win services. My task is to build install package. I decided that Visual Studio install projects are not met my requirements. I design my own installer for this project, because I need to resolve many question and problem in install process. My problem: I need to deploy web-site into IIS, but I don't know how to do it easy. I found Microsoft tool as Web Deployment Tool, but I didn't find any documentation. And must I include this tool into my installer for deployment at destination customer? Another side I found SDC Tasks Library and it looks like a solution for me. But I saw many topics where people had problems and because the project was dead anybody couldn't help them. I know it is a long story... My question: how can I deploy the web-site from another program (I know that IIS versions have some differences and it is another headache), set a virtual directory, application pool (very important), a type of authentification and so forth ??? Thanks.

• Questions about openid and dotnetauthentication

  - by chobo2

  Hi I am looking into openid and dotnetauthentication library. However I still go some outstanding questions. the id that comes back is that unique for each user? Can I store this id in a database as the userId(currently this field is a primary key and unique identifier) I read that you can try to request information such as email address but you may not give it to you. What happens if you need this information? I think it kinda sucks if I have to popup another field right away and ask for their email address and whatever else fields I need. Sort of seems to defeat the purpose a bit as I always considered a benefit of openid is that you don't have to fill out registration forms. Is it better to only have some predefined choices(google,yahoo,openid,facebook). Then letting them type in their own ones(ie gray out the field to let them type in a url). I am thinking of this because it goes back to point number 2 if they type in a provider that does not give me the information that I need I am then stuck. How do you a log person out? Do you just kill the form authentication ticket?

• Type of member is not CLS-compliant

  - by John Galt

  Using Visual Studio 2008 and VB.Net: I have a working web app that uses an ASMX web service which is compiled into its separate assembly. I have another class library project compiled as a separate assembly that serves as a proxy to this web service. This all seems to work at runtime but I am getting this warning at compile time which I don't understand and would like to fix: Type of member 'wsZipeee' is not CLS-compliant I have dozens of webforms in the main project that reference the proxy class with no compile time complaints as this snippet shows: Imports System.Data Partial Class frmZipeee Inherits System.Web.UI.Page Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee Dim dsStandardMsg As DataSet Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load And yet I have one webform (also in the root of the main project) which gives me the "not CLS-compliant" message but yet attempts to reference the proxy class just like the other ASPX files. I get the compile time warning on the line annoted by me with 'ERROR here.. Imports System.Data Partial Class frmHome Inherits System.Web.UI.Page Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee ERROR here Dim dsStandardMsg As DataSet Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load This makes no sense to me. The file with the warning is called frmHome.aspx.vb; all others in the project declare things the same way and have no warning. BTW, the webservice itself returns standard datatypes: integer, string, and dataset.

• jquery form validation, and submit-on-change

  - by Bee

  I want to make all my settings forms across my site confirm that changes are saved, kinda like facebook does if you make changes in a form and then try to navigate away without saving. So I'm disabling the submit button on the forms only enabling if the values change. I then prompt the user to hit save before they leave the page in the case that they do have changes pending. var form = $('form.edit'); if(form.length > 0) { var orig_str = form.serialize(); $(':submit',form).attr('disabled','disabled'); form.on('change keyup', function(){ if(form.serialize() == orig_str) { setConfirmUnload(false); $(':submit',form).attr('disabled','disabled'); } else { setConfirmUnload(true); $(':submit',form).removeAttr('disabled') } }); $('input[type=submit]').click(function(){ setConfirmUnload(false); }); } function setConfirmUnload(on) { window.onbeforeunload = (on) ? unloadMessage : null; } function unloadMessage() { return 'If you navigate away from this page without saving your changes, they will be lost.'; } One of these forms needs some additional validation which I do using jQuery.validate library. e.g. if i wanted to ensure the user can't double submit the form on accident by double clicking on submit or somesuch (the actual validation in question is for a credit-card form and not this simple): $('form').validate({ submitHandler: function(form) { $(':submit', form).attr('disabled','disabled'); form.submit(); } }); Unfortunately both bits are trying to bind to submit button and they're interfering with each other such that the submit button remains disabled no matter what I do and it is impossible to submit the form at all. Is there some way to chain the validations together or something? Or some other way to avoid re-writing the validation code to repeat the "did you change anything in the form" business?

• How to mock/stub a directory of files and their contents using RSpec?

  - by John Topley

  A while ago I asked "How to test obtaining a list of files within a directory using RSpec?" and although I got a couple of useful answers, I'm still stuck, hence a new question with some more detail about what I'm trying to do. I'm writing my first RubyGem. It has a module that contains a class method that returns an array containing a list of non-hidden files within a specified directory. Like this: files = Foo.bar :directory => './public' The array also contains an element that represents metadata about the files. This is actually a hash of hashes generated from the contents of the files, the idea being that changing even a single file changes the hash. I've written my pending RSpec examples, but I really have no idea how to implement them: it "should compute a hash of the files within the specified directory" it "shouldn't include hidden files or directories within the specified directory" it "should compute a different hash if the content of a file changes" I really don't want to have the tests dependent on real files acting as fixtures. How can I mock or stub the files and their contents? The gem implementation will use Find.find, but as one of the answers to my other question said, I don't need to test the library. I really have no idea how to write these specs, so any help much appreciated!

• iPhone: How to use CGContextConcatCTM for saving a transformed image properly?

  - by Irene

  I am making an iPhone application that loads an image from the camera, and then the user can select a second image from the library, move/scale/rotate that second image, and then save the result. I use two UIImageViews in IB as placeholders, and then apply transformations while touching/pinching. The problem comes when I have to save both images together. I use a rect of the size of the first image and pass it to UIGraphicsBeginImageContext. Then I tried to use CGContextConcatCTM but I can't understand how it works: CGRect rect = CGRectMake(0, 0, img1.size.width, img1.size.height); // img1 from camera UIGraphicsBeginImageContext(rect.size); // Start drawing CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextClearRect(ctx, rect); // Clear whole thing [img1 drawAtPoint:CGPointZero]; // Draw background image at 0,0 CGContextConcatCTM(ctx, img2.transform); // Apply the transformations of the 2nd image But what do I need to do next? What information is being held in the img2.transform matrix? The documentation for CGContextConcatCTM doesn't help me that much unfortunately.. Right now I'm trying to solve it by calculating the points and the angle using trigonometry (with the help of this answer), but since the transformation is there, there has to be an easier and more elgant way to do this, right?

• Error 2025: The supplied DisplayObject must be a child of the caller

  - by Mocca

  Hi, sorry, new to actionscript 3. I have a display() function for an object rotator(image based like a QT object movie). It first saves the current image in a helper variable and then allocates a new image, from the library, beneath the old one. To get a nice crossfade effect, the old image's alpha is looped down via enter_frame and then removed. Which is where there seems to be an issue with the display list, maybe recognizing oldImg's value as being already added? (it's not a first pass error) Btw, do i have to remove the old image or can i leave it, for when it's being called up via the mouse position again? (the image number can get fairly large) Does anyone have further insight? Thanks! function display(num:Number):void //num: image number { ... oldImg = newImg; ClassReference = getDefinitionByName("Class"+num) as Class; imgBD = new ClassReference(0,0); newImg = new Bitmap(imgBD); images.addChild(newImg); newImg.x=0; newImg.y=0; } function onEnter(evt:Event):void { if (oldImg) { if (oldImg.alpha > 0) oldImg.alpha -= 0.15; **else images.removeChild(oldImg);** } ... }

• Raspberry Pi broadcast serial port data to local network

  - by D051P0

  I didn't find anything to help me with this problem. What I want is: Serial device sends repeatedly some data to serial port. Raspberry Pi should get this data from RxD and stream it to local network via port 10001 without filtering it. So I can find this device on my pc. This should also work in other direction: Raspberry listen to port 10001 and forward all data from local network to TxD. I'm newbie in Linux World. How can I listen to some port on Raspberry Pi and send broadcast to the same port? I'm using Raspbian Wheezy with soft float. I have found a library Pi4j for Java, that I already use to get and write data from/to serial port. final Serial serial = SerialFactory.createInstance(); serial.addListener(new SerialDataListener() { public void dataReceived(SerialDataEvent event) { forward(event.getData()); } }); event.getData() is a String, which I want to broadcast in my local network. Is it generally a good Idea to use Java for that? I need also a String from port 10001, which I can forward to serial port.

• How to implement a grapher in C#

  - by iansinke

  So I'm writing a graphing calculator. So far I have a semi-functional grapher, however, I'm having a hard time getting a good balance between accurate graphs and smooth looking curves. The current implementation (semi-pseudo-code) looks something like this: for (float i = GraphXMin; i <= GraphXMax; i++) { PointF P = new PointF(i, EvaluateFunction(Function, i) ListOfPoints.Add(P) } Graphics.DrawCurve(ListOfPoints) The problem with this is since it only adds a point at every integer value, graphs end up distorted when their turning points don't fall on integers (e.g. sin(x)^2). I tried incrementing i by something smaller (like 0.1), which works, but the graph looks very rough. I am using C# and GDI+. I have SmoothingMethod set to AntiAlias, so that's not the problem, as you can see from the first graph. Is there some sort of issue with drawing curves with a lot of points? Should the points perhaps be positioned exactly on pixels? I'm sure some of you have worked on something very similar before, so any suggestions? While you're at it, do you have any suggestions for graphing functions with asymptotes? e.g. 1/x^2 P.S. I'm not looking for a library that does all this - I want to write it myself.

• Best way reading from dirty excel sheets

  - by Ten Ton Gorilla

  I have to manipulate some Excel documents with C#. It's a batch process with no user interaction. It's going to parse data into a database, then output nice reports. The data is very dirty and cannot be ready using ADO. The data is nowhere near a nice table format. Best is defined as the most stable(updates less likely to break)/ clear(succinct) code. Fast doesn't matter. If it runs in less than 8 hours I'm fine. I have the logic to find the data worked out. All I need to make it run is basic cell navigation and getvalue type functions. Give me X cell value as string, if it matches Y value with levenshtein distance < 3, then give me Z cell value. My question is, what is the best way to dig into the excel? VSTO? Excel Objects Library? Third Option I'm not aware of?

• Can't post with Perl's Net::Blogger

The main portion of my code looks like this: use Net::Blogger; my $blogger = Net::Blogger->new({ debug => 1, appkey => '0123456789ABCDEF', # doesn't matter? blogid => $blogid, username => $username, password => $password, }); say 'got to here'; my $result = $blogger->newPost({ postbody => \'<p>This is text</p><hr/><p><strong>Whee!</strong></p>', publish => 1, }); say 'done posting'; use Data::Dumper; print Dumper($result); Sure enough, $result is 0 and in checking the blog, nothing has been posted. The error I'm getting when I enable debugging is: Element '' can't be allowed in valid XML message. Died. at /Library/Perl/5.10.1/SOAP/Lite.pm line 1410. What am I doing wrong? If you can suggest an alternative to Net::Blogger, that would be fine.

• Colorbox iFrame content not appearing in IE 8/9

  - by Rocketpig

  I'm using ColorBox to call a few informational modals on-screen and given the client's requirements, the best way to do this is via iFrames (not my first choice but whatever). Everything is working peachy in Chrome, FF, etc. but the iFrame content is not working in any version of IE. The modal wrapper appears but nothing is inside. This is what I've done so far: Changed the doctype to transitional and strict for IE. No dice. Removed the "iframe: true" and replaced it with HTML "Hello". That worked fine and "Hello" appeared in the Colorbox modal. I've removed all stylesheets from the header. No luck so it's not a CSS issue. Just to be sure, I rolled back my JQuery library to 1.6.2 from 1.8.2. Nothing there, either. Any help would be appreciated. This is aggravating. Some code: $(function () { $(".modal-large").colorbox({iframe:true, innerWidth:580, innerHeight:500}); }) HTML: <div class="top-droptext"><a class="modal-large" href="modal/serviceproviderinfo.html">Update Password</a></div>

• Changing type of object in a conditional

  - by David Doria

  I'm having a bit of trouble with dynamic_casting. I need to determine at runtime the type of an object. Here is a demo: include include class PersonClass { public: std::string Name; virtual void test(){}; //it is annoying that this has to be here... }; class LawyerClass : public PersonClass { public: void GoToCourt(){}; }; class DoctorClass : public PersonClass { public: void GoToSurgery(){}; }; int main(int argc, char *argv[]) { PersonClass* person = new PersonClass; if(true) { person = dynamic_cast(person); } else { person = dynamic_cast(person); } person-GoToCourt(); return 0; } I would like to do the above. The only legal way I found to do it is to define all of the objects before hand: PersonClass* person = new PersonClass; LawyerClass* lawyer; DoctorClass* doctor; if(true) { lawyer = dynamic_cast(person); } else { doctor = dynamic_cast(person); } if(true) { lawyer-GoToCourt(); } The main problem with this (besides having to define a bunch of objects that won't be use) is that I have to change the name of the 'person' variable. Is there a better way? (I am not allowed to change any of the classes (Person, Lawyer, or Doctor) because they are part of a library that people who will use my code have and won't want to change). Thanks, Dave

• C++ BigInt multiplication conceptual problem

  - by Kapo

  I'm building a small BigInt library in C++ for use in my programming language. The structure is like the following: short digits[ 1000 ]; int len; I have a function that converts a string into a bigint by splitting it up into single chars and putting them into digits. The numbers in digits are all reversed, so the number 123 would look like the following: digits[0]=3 digits[1]=3 digits[2]=1 I have already managed to code the adding function, which works perfectly. It works somewhat like this: overflow = 0 for i ++ until length of both numbers exceeded: add numberA[ i ] to numberB[ i ] add overflow to the result set overflow to 0 if the result is bigger than 10: substract 10 from the result overflow = 1 put the result into numberReturn[ i ] (Overflow is in this case what happens when I add 1 to 9: Substract 10 from 10, add 1 to overflow, overflow gets added to the next digit) So think of how two numbers are stored, like those: 0 | 1 | 2 --------- A 2 - - B 0 0 1 The above represents the digits of the bigints 2 (A) and 100 (B). - means uninitialized digits, they aren't accessed. So adding the above number works fine: start at 0, add 2 + 0, go to 1, add 0, go to 2, add 1 But: When I want to do multiplication with the above structure, my program ends up doing the following: Start at 0, multiply 2 with 0 (eek), go to 1, ... So it is obvious that, for multiplication, I have to get an order like this: 0 | 1 | 2 --------- A - - 2 B 0 0 1 Then, everything would be clear: Start at 0, multiply 0 with 0, go to 1, multiply 0 with 0, go to 2, multiply 1 with 2 How can I manage to get digits into the correct form for multiplication? I don't want to do any array moving/flipping - I need performance!

  I know there are many tutorials online, but I could not make them work :( maybe something particularly wrong with my system :/ My Controller localpath is: /localhost/rl/applications/backend/controller/ Controller: function do_upload() { $config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100'; $config['max_width'] = '1024'; $config['max_height'] = '768'; $this->load->library('upload', $config); if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); $this->load->view('add_image', $error); } else { $data = array('upload_data' => $this->upload->data()); $data['id'] = $this->input->post['id_work']; $this->load->view('add_image', $data); } } My View localpath is: /localhost/rl/applications/backend/view/ View: echo form_open_multipart('do_upload'); <ul class="frm"> <li><label>File: *</label><input type="file" name="userfile" class="frmlmnt" size="50" /></li> <li><label></label><input type="submit" class="btn" value="Upload" /></li> </ul> </form> Maybe I do something wrong with path

• C++ MACRO that will execute a block of code and a certain command after that block.

  - by Poni

  void main() { int xyz = 123; // original value { // code block starts xyz++; if(xyz < 1000) xyz = 1; } // code block ends int original_value = xyz; // should be 123 } void main() { int xyz = 123; // original value MACRO_NAME(xyz = 123) // the macro takes the code code that should be executed at the end of the block. { // code block starts xyz++; if(xyz < 1000) xyz = 1; } // code block ends << how to make the macro execute the "xyz = 123" statement? int original_value = xyz; // should be 123 } Only the first main() works. I think the comments explain the issue. It doesn't need to be a macro but to me it just sounds like a classical "macro-needed" case. By the way, there's the BOOST_FOREACH macro/library and I think it does the exact same thing I'm trying to achieve but it's too complex for me to find the essence of what I need. From its introductory manual page, an example: #include <string> #include <iostream> #include <boost/foreach.hpp> int main() { std::string hello( "Hello, world!" ); BOOST_FOREACH( char ch, hello ) { std::cout << ch; } return 0; }

• CFStrings and storing them into models, related topics

  - by Jasconius

  I have a very frustrating issue that I believe involves CFStringRef and passing them along to custom model properties. The code is pretty messy right now as I am in a debug state, but I will try to describe the problem in words as best as I can. I have a custom model, User, which for irrelevant reasons, I am storing CF types derived from the Address Book API into. Examples include: Name, email as NSStrings. I am simply retrieving the CFStringRef value from the AddressBook API and casting as a string, whereupon I assign to the custom model instance and then CFRelease the string. These NSString properties are set as (nonatomic, retain). I then store this model into an NSArray, and I use this Array as a datasource for a UITableView When accessing the object in the cellForRowAtIndexPath, I get a memory access error. When I do a Debug, I see that the value for this datasource array appears at first glance to be corrupted. I've seen strange values assigned to it, including just plain strings, such as one that I fed to an NSLog function in earlier in the method. So, the thing that leads me to believe that this is Core Foundation related is that I am executing this exact same code, in the same class even, on non-Address Book data, in fact, just good old JSON parsed strings, which produce true Cocoa NSStrings, that I follow the same exact steps to create the datasource array. This code works fine. I have a feeling that my (retain) property declaration and/or my [stringVar release] in my custom model dealloc method may be causing memory problems (since it is my understanding that you shouldn't call a Cocoa retain or release on a CF object). Here is the code. I know some of this is super-roundabout but I was trying to make things as explicit as possible for the sake of debugging. NSMutableArray *friendUsers = [[NSMutableArray alloc] init]; int numberOfPeople = CFArrayGetCount(people); for (int i = 0; i < numberOfPeople; i++) { ABMutableMultiValueRef emails = ABRecordCopyValue(CFArrayGetValueAtIndex(people, i), kABPersonEmailProperty); if (ABMultiValueGetCount(emails) > 0) { User *addressContact = [[User alloc] init]; NSString *firstName = (NSString *)ABRecordCopyValue(CFArrayGetValueAtIndex(people, i), kABPersonFirstNameProperty); NSString *lastName = (NSString *)ABRecordCopyValue(CFArrayGetValueAtIndex(people, i), kABPersonLastNameProperty); NSLog(@"%@ and %@", firstName, lastName); NSString *fullName = [NSString stringWithFormat:@"%@ %@", firstName, lastName]; NSString *email = [NSString stringWithFormat:@"%@", (NSString *)ABMultiValueCopyValueAtIndex(emails, 0)]; NSLog(@"the email: %@", email); [addressContact setName:fullName]; [addressContact setEmail:email]; [friendUsers addObject:addressContact]; [firstName release]; [lastName release]; [email release]; [addressContact release]; } CFRelease(emails); } NSLog(@"friend count: %d", [friendUsers count]); abFriends = [NSArray arrayWithArray:friendUsers]; [friendUsers release]; All of that works, every logging statement returns as expected. But when I use abFriends as a datasource, poof. Dead. Is my approach all wrong? Any advice?

• Re-authentication required for registered-path links (to ASP.NET site) coming to IE from PowerPoint

  - by Daniel Halsey

  We're using URL routing based on Phil Haack's example, with config modifications based on MSDN Library article #CC668202, to provide "shareable" links for a ASP.NET forms site, and have run into a strange issue: For users attempting to open links from PowerPoint presentations, and who have IE set as their default browser, using one of these links forces (forms-based) re-authentication, even in the same browser instance with a live session. Info: We know the session is still alive. (Page returns information for the currently logged-in user; confirmed via debug watches) This doesn't happen with other browsers (FF, Chrome) or with other programs (Notepad++) as the URL source. We do not have a default path set, as this caused issues with root path handling at initial login. This primarily happens with PowerPoint, but will also happen in Word and OCS. On some machines, even after changing the default browser, Office apps will continue to use IE for these links, forcing this error. (A potential registry fix for this failed, but even if it had worked, we can't control default browser choice for our users.) We can't figure out if this is an Office oddity or is being caused by our decision to use app-level URL routing (rather than IIS rewriting). Has anyone else encountered this and found a solution?

• Pre Project Documentation

  - by DeanMc

  I have an issue that I feel many programmers can relate to... I have worked on many small scale projects. After my initial paper brain storm I tend to start coding. What I come up with is usually a rough working model of the actual application. I design in a disconnected fashion so I am talking about underlying code libraries, user interfaces are the last thing as the library usually dictates what is needed in the UI. As my projects get bigger I worry that so should my "spec" or design document. The above paragraph, from my investigations, is echoed all across the internet in one fashion or another. When a UI is concerned there is a bit more information but it is UI specific and does not relate to code libraries. What I am beginning to realise is that maybe code is code is code. It seems from my extensive research that there is no 1:1 mapping between a design document and the code. When I need to research a topic I dump information into OneNote and from there I prioritise features into versions and then into related chunks so that development runs in a fairly linear fashion, my tasks tend to look like so: Implement Binary File Reader Implement Binary File Writer Create Object to encapsulate Data for expression to the caller Now any programmer worth his salt is aware that between those three to do items could be a potential wall of code that could expand out to multiple files. I have tried to map the complete code process for each task but I simply don't think it can be done effectively. By the time one mangles pseudo code it is essentially code anyway so the time investment is negated. So my question is this: Am I right in assuming that the best documentation is the code itself. We are all in agreement that a high level overview is needed. How high should this be? Do you design to statement, class or concept level? What works for you?
