• 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?

• Java: How can I create good looking class docs with Javadoc?

  - by Cheeso

  I'd like to create HTNML documentation for a Java class library that includes programming guide information - beyond just a class reference code examples in the reference doc collapsible regions I want it to look well-styled. Something like this: I think that Javadoc exposes a doclet API that allows other parties to provide doc generation integrated in Javadoc. Is there a doclet option that I can use (for free) that does something a little nicer than the standard javadoc output? I tried googling for this but no luck. Suggestions?

• Assign value to list

  - by Kenneth B

  Hello First and foremost. I'm totally new to "programming" in Excel. I'm trying to make a price calculator, that calculates the price when I use my printer. I have made some lists so it's easy to perform the calculations. Single or duplex: Singlex/Duplex Format: SRA3 / A4 / SRA3 High Gloss The idea is that if I type in an amount of 100 prints, choose SRA3 format on the list, and choose Duplex on the other list. the calculation would look like this: This is how it's calculated: Paper + (print x sides) = Price of the print job Print prices Per page (singlex or duplex): 0,6 Paper format and price: A4 reg. paper: 0,2 SRA3 High Gloss: 1,25 SRA3 reg. paper: 1 Does anyone know about this???

• 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.

• C# 2D Vector Graphics Game using DirectX or OpenGL?

  - by Brian

  Hey Guys, So it has been a while since I have done any game programming in C#, but I have had a recent bug to get back into it, and I wanted some opinions on what configuration I should use. I wanted to use C# as that is what I use for work, and have become vary familiar with. I have worked with both DirectX and OpenGL in the past, but mostly in 3D, but now I am interested in writing a 2D game with all vector graphics, something that resembles the look of Geometry Wars or the old Star Wars arcade game. Key points I am interested in: • Ease of use/implementation. • Easy on memory. (I plan on having a lot going on at once) • Looks good, I don't want curve to look pixelated. • Maybe some nice effects like glow or particle. I am open to any and all suggestions, maybe even something I have not thought of... Thanks in advance!

• In Visual Studio 2008, how can I make control+click do a "Go To Definition"?

  - by Blorgbeard

  I know this is not strictly about programming, but it's pretty close. Anyway, in Delphi, you can hold control and click on a method to jump to its definition. In VS2008, you have to right-click and select "Go To Definition". I use this function quite often, so I'd really like to get VS to behave like delphi in this regard - its so much quicker to ctrl+click. I don't think there's a way to get this working in base VS2008 - am I wrong? Or maybe there's a plugin I could use? Edit: Click then F12 does work - but isn't really a good solution for me.. It's still way slower than ctrl+click. I might try AutoHotkey, since I'm already running it for something else. Edit: AutoHotkey worked for me. Here's my script (I'm a complete n00b, so it's probably suboptimal): SetTitleMatchMode RegEx #IfWinActive, .* - Microsoft Visual Studio ^LButton::Send {click}{f12}

• General question: Filesystem or database?

  - by poeschlorn

  Hey guys, i want to create a small document management system. there are several users who store their files. each file which is uploaded contains an info which user uploaded it and the document content itself. In a view there are displayed all files of ONE specific user, ordered by date. What would be better: 1) giving the documents a name or metadata(XML) which contain the date and user (and iterate through them to get the metadata) or 2) giving the files a random/unique name and store metadata in a DB? something like this: date | user | filename What would you say and why? The used programming language is java and the DB is MySQL.

• How is fseek() implemented in the filesystem?

  - by pajton

  This is not a pure programming question, however it impacts the performance of programs using fseek(), hence it is important to know how it works. A little disclaimer so that it doesn't get closed. I am wondering how efficient it is to insert data in the middle of the file. Supposing I have a file with 1MB data and then I insert something at the 512KB offset. How efficient would that be compared to appending my data at the end of the file? Just to make the example complete lets say I want to insert 16KB of data. I understand the answer varies depending on the filesystem, however I assume that the techniques used in common filesystems are quite similar and I just want to get the right notion of it.

• Accessing a webpage in C++

  - by wyatt

  Is there a good, simple library which allows C++ to load a webpage? I just want to grab the source as text. I'm not using any IDE or significant library, just straight command line. Tangentially, is there something fundamental I'm missing about programming in C++? I would think any language in common use today would have droves of web-based functionality, being so central to computer usage, but I can find next to no discussion on how to accomplish it. I realise C++ significantly predates the modern internet, so it lacking any core ability in the regard is reasonable, but the fact that relevant libraries seem so sparse is baffling. Thanks for your help.

• Questions about "casting operation" in OOP

  - by rhapsodyn

  When programming, we usually use some type-casting operations. When the casting happens on the objects "on the same level", it feels ok. But when it happens on the ojects "on the different levels"(mainly between father and son), it feels weird. Considering this: Class Son extends Father WhenSon s = (Son)father;, it's absolutely unreasonable. Because a "Son" is not a "Father" anymore, "Son" may grow up with some new properties "Father" doesn't have, the casting operation makes these properties unknown. On the other hand, Father f = (Father)son seems reasonable, but according to LSP "An instance of a derived should be able to replace any instance of its superclass" A "Son" can do anything his "Father" can, so the casting operation seems useless. So can i say that these casting operations are agaisnt OO design principle but necessary?

• Which is faster in memory, ints or chars? And file-mapping or chunk reading?

  - by Nick

  Okay, so I've written a (rather unoptimized) program before to encode images to JPEGs, however, now I am working with MPEG-2 transport streams and the H.264 encoded video within them. Before I dive into programming all of this, I am curious what the fastest way to deal with the actual file is. Currently I am file-mapping the .mts file into memory to work on it, although I am not sure if it would be faster to (for example) read 100 MB of the file into memory in chunks and deal with it that way. These files require a lot of bit-shifting and such to read flags, so I am wondering that when I reference some of the memory if it is faster to read 4 bytes at once as an integer or 1 byte as a character. I thought I read somewhere that x86 processors are optimized to a 4-byte granularity, but I'm not sure if this is true... Thanks!

• databind a DropDownList control with a list of all sub directories that exist in a particular direct

  - by sushant

  I am wanting to databind a DropDownList control with a list of all sub directories that exist in a particular directory on the server. The directory I want to search is in the root of the application. I am fairly new to programming and I'm not sure where to even start. I found this code on a website: Dim root As String = "C;\" Dim folders() As String = Directory.GetDirectories(root) Dim sb As New StringBuilder(2048) Dim f As String For Each f In folders Dim foldername As String = Path.GetFileName(f) sb.Append("<option>") sb.Append(foldername) sb.Append("</option>") Next Label3.Text = "<select runat=""sever"" id=""folderlist""" & sb.ToString() & "</select>" I guess this is vb. but my tool is in asp, so is their something similar in vbscript so that I can use it.

• What are the things Java got right?

  - by hamletdarcy

  What are the things that Java (the language and platform) got categorically right? In other words, what things are more recent programming languages preserving and carrying forward? Some easy answer are: garbage collection, a VM, lack of pointers, classloaders, reflection(?) What about language based answers? Please don't list the things Java did wrong, just right. (note by Mark Harrison) This is an interesting and useful question, especially for those of us who don't use java regularly. I'm voting for reopening. Please don't close as argumentative, as it doesn't seem to be causing any arguments.

• How do I convert a single char in string to an int

  - by Guest

  Keep in mind, if you choose to answer the question, I am a beginner in the field of programming and may need a bit more explanation than others as to how the solutions work. Thank you for your help. My problem is that I am trying to do computations with parts of a string (consisting only of numbers), but I do not know how to convert an individual char to an int. The string is named "message". for (int place = 0; place < message.size(); place++) { if (secondPlace == 0) { cout << (message[place]) * 100 << endl; } } Thank you.

• C++ MFC add combo box string item from a widget ID

  - by OzBarry

  I've added a combo box in the gui editor in MSVC 2010 pro in my MFC project. I have a list of strings I am grabbing from an external source and want to add them to my combo box. I've searched for a while, and every post seems to suggest I need to use the CComboBox class, however, I have no idea how to get the class variable from the resource ID of the combobox element in the gui editor. In summary, how do I add a string to my combo box, either using a macro (like CB_ADDSTRING(RESOURCE_ID, "my string");) or using CComboBOx (something like CComboBox::GetObject(RESOURCE_ID)->AddString("blah");). I do not do much win32 api/mfc programming, and just started fiddling around with it.

• How does exactly Qt works?

  - by Somebody still uses you MS-DOS

  I have seen that you can write your application in Qt, and it can be run in different operating systems. And - correct me if I'm wrong - you don't need to have Qt already installed in all of these platforms. How exactly this approach works? Does Qt compiles to the desired platform, does it bundle some "dlls" (libs), how does it do it? Is different from programming a Java application for the sake of cross-platform? If you use Python to write a Qt application with Python bindings, does the final user needs to have Python installed?

• Does program need additional symbols from .so shared library except those declared in header file?

  - by solotim

  In C programming, I thought that a object file can be successfully linked with a .so file as long as the .so file offers all symbols which have been declared in the header file. Suppose I have foo.c, bar.h and two libraries libbar.so.1 and libbar.so.2. The implementation of libbar.so.1 and libbar.so.2 is totally different, but I think it's OK as long as they both offers functions declared in bar.h. I linked foo.o with libbar.so.1 and produced an executable: foo.bin. This executable worked when libbar.so.1 is in LD_LIBRARY_PATH.(of course a symbolic link is made as libbar.so) However, when I change the symbolic link to libbar.so.2, foo.bin could not run and complainted this: undefined symbol: _ZSt4cerr I found this symbol type is 'B' and it does not appear in libbar.so.2. Obviously this symbol has nothing to do with those functions I decared in bar.h. What's wrong here?

• Python: Data Object or class

  - by arg20

  I enjoy all the python libraries for scraping websites and I am experimenting with BeautifulSoup and IMDB just for fun. As I come from Java, I have some Java-practices incorporated into my programming styles. I am trying to get the info of a certain movie, I can either create a Movie class or just use a dictionary with keys for the attributes. My question is, should I just use dictionaries when a class will only contain data and perhaps almost no behaviour? In other languages creating a type will help you enforce certain restrictions and because of type checks the IDE will help you program, this is not always the case in python, so what should I do? Should I resort to creating a class only when there's both, behaviour and data? Or create a movie class even though it'll probably be just a data container? This all depends on your model, in this particular case either one is fine but I'm wondering about what's a good practice.

• GoTo statements and alternatives in VB.NET

  - by qais

  I've posted a code snippet on another forum asking for help and people pointed out to me that using GoTo statements is very bad programming practice. I'm wondering: why is it bad? What alternatives to GoTo are there to use in VB.NET that would be considered generally more of a better practice? Consider this snippet below where the user has to input their date of birth. If the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if there's a better way to do this, I'd appreciate if you could tell me that also :D) How would I be able to loop back to ask the user again? retryday: Console.WriteLine("Please enter the day you were born : ") day = Console.ReadLine If day > 31 Or day < 1 Then Console.WriteLine("Please enter a valid day") GoTo retryday End If

• should i lisense 3rd party controls?

  - by jhon

  some of you will say that this post is not programming related, i think it is! i developed a WebApplication that uses several 3rd party controls using asp.net (c#). i did not buy any license for the 3rd party controls that i am using because i am a freelancer and the controls are too much expensive for me to buy. i already sold the application to several mini-companies that don't care about the license issue. so my question: is it possible that i get sued or caught because of this crime? if yes, then how can they know who am i?

• Claims-based Authentication: Are strings the essence of claims?

  - by Rising Star

  I've been programming with claims-based authentication for some time now with Windows Identity Foundation. It appears to me that in Windows Identity Foundation, once a user is logged in, the claims are basically strings of information that describe the user. With the old role-based authentication, I could say that a user is or is not a member of a given group, but with claims-based authentication, I can now have strings of information that describe a user. "This user is female". This user was born on "July 6, 1975". "This user logged in using a USB key". Is it the essence of claims-based authentication,that I have strings of information about the user given to the application by the framework?

• Facebook API - Get comments

  - by Simon R

  Our business has a Facebook Fan Page. The fan page doesn't seem to generate any emails to us when updates are made to the page, whether someone adds a new status or someone comments on one of the statuses etc. Currently, we are running a very crude script to grab the content of the page and then use regular expressions to get the information we require. Obviously this is not fool proof and I'm looking into alternatives to this method. I've been looking at the facebook API and wonder if the rest server might be an option. I cannot, however, seem to find out how to return information of fan page statuses and their comments. Is anyone able to direct me how to use the API to retrieve this information. I am an admin of the fan page. The programming language I'm using is PHP. Many thanks.

I know the definition of a protocol, being new to this c++ programming is quite a challenging task.I am creating a Multi-threaded chat using SDL/C++, this is a learning experience for me and now i have encounter a hump in which I need to overcome but understanding it is a little more difficult than I had thought.I need to make a chat protocol of some sort, I think...but am stump. Up until this point i have been sending messages in strings of characters.Now that am improving the application to the point where clients can register and login, I need a better way to communicating with my clients and server. thank you.

• technique for how to debug macros in C

  - by Dervin Thunk

  Hi. So I have the (mostly vilified) #define MAX( a, b ) ( ((a) > (b)) ? (a) : (b) ) somewhere in a program (yes, yes, I know). At some point in the code there is a comparison X>-1?, where X is (as far as I can tell) a (signed) integer. The line is j += MAX(bmGs[i], bmBc[(int)y[i + j]] - m + 1 + i);, where y here is a char*. Not necessarily surprisingly, I find that the macro is returning -1 as the larger number (I'm guessing too long a number for int or an unsigned issue, but I can't find it). I would like to know techniques you guys may have for finding these kinds of errors. Notice that I'm not asking for programming advice about whether or not to use that macro, I'm sure folks are dying to tell me I should refrain from things like that, but the question is going somewhere else. Thanks.
