  • Custom nib UITableViewCell height

    - by Chuck
    I've created a custom UITableViewCell in IB, linked it to the root view controller's property for it, and set it up in CellForRowAtIndexPath. But the height of my drawn cells doesn't match what I setup in IB, advice? Here's some screenshots and the code. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *AddressCellIdentifier = @"AddressCellIdent"; UITableViewCell *thisCell = [tableView dequeueReusableCellWithIdentifier:AddressCellIdentifier]; if (thisCell == nil) { [[NSBundle mainBundle] loadNibNamed:@"AddressCell" owner:self options:nil]; thisCell = addressCell; self.addressCell = nil; } return thisCell ; } addressCell is a @property (nonatomic, assign) IBOutlet UITableViewCell *addressCell;, and is linked up in IB to the file's owner (the table view controller). I'm using the example from Apple's table view programming guide.

  • How much trust can I put behind a computer system? How can I measure trust?

    - by danmine
    How much trust can I put in a standard computer running windows? To what certainty can I be sure it will run my code the way I wrote it? How can I be sure that if I declare something like "int j = 5;", j will alway be 5? Is there a way to measure trust in a standard x86 computer system? What kind of protections are there to make sure that j = 5? I'm thinking about critical systems where nothing can be off even by one bit and everything must run exactly the way it was written to run.

  • Is there a server side API for Team Foundation Server?

    - by Ralph Shillington
    It would seem there is precious little documentation on programming against a TFS 2010 instance. What bits I have found, have next to nothing in the case of documentation beyond barebones listing of client access classes and their members, most likely autogenerated from the code comments. As I'm interested in building a silverlight client against TFS, I will need access to a server side API. Ideally the silverlight app will talk to my server (mainly for work items) and my server will in turn talk to the TFS server for the goods. Where is the doumentation (if any) for this kind of TFS integration?

  • Associate List<T>.Remove to an event in C#?

    - by Uri
    Hi guys, I have a Products:List<Product> class. I'd like to make it so that every time that I remove an item from that list, my program decreases a counter. Is there a way to do it without overriding the Remove method or decreasing it manually? And if there is none, anybody knows where I can find the code for the Remove method? Thanks! I thought about associating the Remove method to an event, but I don't know how to do it without overriding it or creating another method with the Remove method inside it. Excuse me for my ignorance, but I'm just getting into OOP programming.

  • C# programmer - necessary to learn C/C++?

    - by Kurresmack
    Hey, I have been programming now for a couple of years. But never any low level language. I started off with some java and some VB. Then I went over to VB.NET and now for a while I have been writing C#. As you see, I have never written any low level language where I had to deal with memory management. Is this something I should do, like a route of passage that every programmer should go through? I am a bit keen on trying to perhaps writing in assembler directly. This would suit me personally good as I have 2 parents that have been writing assembler for ages. Is it necessary for a professional programmer these days to know how to manually manage memory?

  • Find the gender from a name

    - by Ramesh
    Hi guys, I recently confronted with a weird yet interesting question. The questions is as follows: Need to write a program which can give the gender as output based on the name. Example: INPUT -- John Michael Britney OUTPUT-- male male female So this is the output I expect. I tried a lot to solve, but I really was not able to crack it. I will be really thankful to this site for giving me an opportunity to share this question. Actually this is asked in a programming contest as a flyer problem, so I thought this can be programmed.

  • VST plugin : using FFT on audio input buffer with arbitrary size, how ?

    - by Led
    I'm getting interested in programming a VST plugin, and I have a basic knowledge of audio dsp's and FFT's. I'd like to use VST.Net, and I'm wondering how to implement an FFT-based effect. The process-code looks like public override void Process(VstAudioBuffer[] inChannels, VstAudioBuffer[] outChannels) If I'm correct, normally the FFT would be applied on the input, some processing would be done on the FFT'd data, and then an inverse-FFT would create the processed soundbuffer. But since the FFT works on a specified buffersize that will most probably be different then the (arbitrary) amount of input/output-samples, how would you handle this ?

  • Does anyone know of a way to easily convert a PDF to a docx format programmatically

    - by Rob
    We have a couple 3rd party systems that give us PDFs. We would like to convert those PDFs for display on the web without using an Adobe product. Ideally we would like to use Silverlight to render the PDFs but are having trouble converting from a PDF to Xaml or using docx format as a middle man. There are lots of libraries that give PDFs but that is not what we need. If there is a library out there that does this, a .net lib would be preferable but we can run the conversion using the command line as well if that is an option.

  • printing out posts

    - by yCalleecharan
    Hi, I'm using the Firefox browser and trying to print out my posts (and replies). The pdf output doesn't include the comments in the posts. How to make sure that everything which is on the page gets printed? Same goes for codes for which are in a window. Only the visible part of the code gets printed. These are not programming questions :) but I hope that someone can suggest how to get proper printouts of the posts. Thanks a lot...

  • How should I go about learning Python?

    - by user345690
    I am currently learning PHP and want to learn about OOP. *1.*I know Python is a well-organized and is all OOP, so would learning Python be a wise choose to learn OOP? The thing is I am more towards web development then just general programming, and I know Python is just a general purpose language, but there is Django. *2*So how should I go about learning Python if I am lending towards web development? Is there any good books/websites that help me learn Python for web development? 3. Is there any free webhosting companies that allow Python? I never used Python before, only PHP, and not sure how it works? Can I run Python on a localhost?

  • Traffic consumed by Team Foundation Server 2010

    - by micha12
    We are currently selecting a source control and issue tracking software, and are looking towards Team Foundation Server 2010. Some participants of our project often have slow Internet connection (for example during travel), and therefore it is important for us to have a source control system that does not consume too much traffic. I was unable to find information on traffic consumption when using TFS 2010. Does anyone has such info? Does TFS 2010 support traffic compression? Do other source control systems (like SVN, for example) produce less or more traffic than TFS 2010?

  • Visual Studio Add-in Exec running Automatically

    - by NewProgrammer
    Hey guys, I have a dilemma that I am uncertain about, as I not sure if it's is exactly possible for a Visual Studio Add-in to run its code automatically. I need an add-in that can run passively, like a logger for Visual Studios. However, the Exec method that I know so far can only execute commandbar functionality, but I need the code to execute when the user right-clicks, or select a line of text. I was able to make an automatic logger if i put my code in the "querystatus", but that would be considered bad programming, and it does not log when I simply select a piece of text. Does anyone know how to make a passive or automatic running code in Visual Studios?

  • Why There is a difference between assembly languages like Windows, Linux ?

    - by mcaaltuntas
    I am relatively new to all this low level stuff,assembly language.. and want to learn more detail. Why there is a difference between Linux, Windows Assembly languages? As I understand when I compile a C code Operating system does not really produce pure machine or assembly code, it produces OS dependent binary code.But why ? For example when I use a x86 system, CPU only understands x86 ASM am I right?.So Why we dont write pure x86 assembly code and why there are different assembly variations based on Operating system? If we would write pure ASM or OS produce pure ASM there wouldn't be binary compatilibty issues between Operating systems or Not ? I am really wondering all reasons behind them. Any detailed answer, article, book would be great. Thanks.

  • Manipulate Excel workbooks programmatically

    - by Tom
    I have an Excel workbook that I want to use as a template. It has several worksheets setup, one that produces the pretty graphs and summarizes the numbers. Sheet 1 needs to be populated with data that is generated by another program. The data comes in a tab delimited file. Currently the user imports the tab delimited file into a new Workbook, selects all and copies. Then goes to the template and pastes the data into sheet1. This is a large amount of data, 269 columns and over 135,000 rows. It’s a cumbersome process and the users are not experienced Excel users. All they really want is the pretty graphs. I would like to add a step after the program that generates the data to programmatically automate the process the user currently must do manually. Can anyone suggest the best method/programming language that could accomplish this?

  • System("pause"); - Why is it wrong?

    - by Faken
    Here's a question that I don't quite understand: The command, System("pause"); is taught to new programmers as a way to pause a program and wait for a keyboard input to continue. However, it seems to be frowned on by many veteran programmers as something that should not be done in varying degrees. Some people say it is fine to use. Some say it is only to be used when you are locked in your room and no one is watching. Some say that they will personally come to your house and kill you if you use it. I, myself am a new programmer with no formal programming training. I use it because I was taught to use it. What I don't understand is that if it is not something to be used, then why was I taught to use it? Or, on the flip side, is it really not that bad after all? What are your thoughts on this subject?

  • JVM specification and Java compiler code useful for SCJP preparation ?

    - by BenoitParis
    I'm preparing the SCJP exam with the almost official study book ("SCJP Sun Certified Programmer for Java 6 Exam 310-065") I understand that Java programming is writting code that fulfills a certain high-level contract; So that Java can stay platform-independent. However, I have trouble understanding and remembering things when it comes to highly specific SCJP items (and they are numerous) The book stays high-level and does not provide examples of how one compiler would handle things. This is the same thing for runtime issues (JVM level): things are too much abstract for me. Rules often seems arbitrary and therefore, with no well defined purpose, are difficult to remember. Or maybe it's that sometimes I just don't get the underlying purpose. And here is the question: Would a JVM specification and/or some java compiler code help in preparing the SCJP? Have you had the need for such material or is the book sufficient enough? Also, please share the resources you used, apart from the book.

  • Universal syntax file format?

    - by Isaiah
    Hey as a project to improve my programing skills I've begun programing a nice code editor in python to teach myself project management, version control, and gui programming. I was wanting to utilize syntax files made for other programs so I could have a large collection already. I was wondering if there was any kind of universal syntax file format much in the same sense as .odt files. I heard of one once in a forum, it had a website, but I can't remember it now. If not I may just try to use gedit syntax files or geany. thanks

  • Transfer of directory structure over network

    - by singh
    I am designing a remote CD/DVD burner to address hardware constraints on my machine. My design works like this: (analogous to a network printer) Unix-based machine (acts as server) hosts a burner. Windows-based machine acts as client. Client prepares data to burn and transfers it to the server. Server burns the data on CD/DVD. My question is: what is the best protocol to transfer data over the network (Keeping the same directory hierarchy) between different operating systems?

  • What technology to use for a RIA

    - by user297159
    I have to develop a online business software solution (similar to ERP) for a company to manage the information exchange for internal use and with external partners. It should be online. What technology should I use, I have checked framewroks like: Flex, Silverlight, Google/GWT, sencha (ExtJS), jQuery, DoJo, Telereik, Infrajistics and others similar. But they seam to be very low level programming. May be this is advantage for other projects, where you need more flexibility, but this project is stright forward. I need something more focused on business software (tables, forms, processes) where and eventually more efficient with less coding, or something I can save time. Is force.com an option? But I can not install this on the customer's servers... Do you have any ideas for me for a web based framework focused on business applications?

  • Suggested C++ books?

    - by Josh Bradley
    Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

  • Metric to measure object-orientedness

    - by Jono
    Is there a metric that can assist in determining the object-orientedness of a system or application? I've seen some pretty neat metrics in the .NET Reflector Add-ins codeplex project, but nothing like this yet. If such a metric doesn't exist, would it even be possible or useful? There are the 3 supposed tenets of object-oriented programming: encapsulation, inheritance, and polymorphism; a tool that ranked programs against these might be able to show areas of a C# (or similar) code base where the whole object-oriented ideal was discarded, and perhaps how many bugs are associated with that area versus the rest of the project.

  • Using typedefs (or #defines) on built in types - any sensible reason?

    - by jb
    Well I'm doing some Java - C integration, and throught C library werid type mappings are used (theres more of them;)): #define CHAR char /* 8 bit signed int */ #define SHORT short /* 16 bit signed int */ #define INT int /* "natural" length signed int */ #define LONG long /* 32 bit signed int */ typedef unsigned char BYTE; /* 8 bit unsigned int */ typedef unsigned char UCHAR; /* 8 bit unsigned int */ typedef unsigned short USHORT; /* 16 bit unsigned int */ typedef unsigned int UINT; /* "natural" length unsigned int*/ Is there any legitimate reason not to use them? It's not like char is going to be redefined anytime soon. I can think of: Writing platform/compiler portable code (size of type is underspecified in C/C++) Saving space and time on embedded systems - if you loop over array shorter than 255 on 8bit microprocessor writing: for(uint8_t ii = 0; ii < len; ii++) will give meaureable speedup.

  • How can i convert between F# List and F# Tuple?

    - by ksharp
    Is there some way to convert between F# List and F# Tuple? For example: [1;2;3] -> (1,2,3) (1,2,3,4) -> [1;2;3;4] I need two Functions to do that: let listToTuple list = ... let tupleToList tuple = ... Thank you in advance. I think reflection is necessary to this problem. I know the performance is not good. I have to pay the cost of breaking functional programming rule.

  • WPF Labels look fine in XP, but are cut off at the bottom in Vista and Windows 7.

    - by juharr
    The following xaml looks fine in XP, but the bottom of the text gets cut off in Vista and Windows 7. <Grid> <Border Height="86" Margin="10,54,10,0" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="1"/> <Label Height="22" Width="100" Margin="15,43,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Background="White">Text Over Border</Label> </Grid> I realize that I could just increase the Height of the label, but I'm guessing I'll have problems with systems that have different resolution settings, or large text settings. Is there a better way to lay this out?
