  • MinGW/GCC Delay Loaded DLL equivalent?

    - by VoiDeD
    Hello, I'm trying to port some old MSVC C++ code to MinGW/GCC. One problem is that the project relies heavily on the /DELAYLOAD option for functions that aren't always used, and where the proper dll is located at runtime. Is there such a similar option on MinGW/GCC? This code is targeting the windows platform.

  • Access variables from a number of sources

    - by mac_55
    I'm creating my first game, and I've currently set up a 'GameState' class, to store player health etc. inside. This class is currently instantiated from the AppDelegate as I need to access it from all over my game. This is fine. For each class I'm working in, I can access the app delegate, and then find the GameState object... however, it seems very messy. I'm tempted to find a way (I'm still a newbie) to define the GameState instance as being some sort of global variable so that I can access it from all over with ease... but my little bit of reading on variable scope makes me uneasy about doing this, even if I knew how. Any ideas of the best way to define and access this class? It'll be used for everything from player health, to items they've found, any personalisation etc. Thanks!

  • SQL: Join vs. subquery

    - by Col. Shrapnel
    I am an old-school MySQL user and always preferred JOIN over sub-query. But nowadays everyone uses sub-query and I hate it, dunno why. Though I've lack of theoretical knowledge to judge myself if there are any difference. Well, I am curious if sub-query as good as join and there is no thing to worry about?

  • What is your laptop's display size?

    - by grigy
    I want to get a new laptop and not sure what display size is the optimal. I need it for programming while I'm traveling. So the balance is between portability and usability. My old laptop is 15.4" and I think it's big and heavy for travel.

  • Python + PostgreSQL + strange ascii = UTF8 encoding error

    - by Claudiu
    I have ascii strings which contain the character "\x80" to represent the euro symbol: >>> print "\x80" € When inserting string data containing this character into my database, I get: psycopg2.DataError: invalid byte sequence for encoding "UTF8": 0x80 HINT: This error can also happen if the byte sequence does not match the encodi ng expected by the server, which is controlled by "client_encoding". I'm a unicode newbie. How can I convert my strings containing "\x80" to valid UTF-8 containing that same euro symbol? I've tried calling .encode and .decode on various strings, but run into errors: >>> "\x80".encode("utf-8") Traceback (most recent call last): File "<pyshell#14>", line 1, in <module> "\x80".encode("utf-8") UnicodeDecodeError: 'ascii' codec can't decode byte 0x80 in position 0: ordinal not in range(128)

  • Convert XCode view-based app to navigation-based app?

    - by Wally
    Newbie question: is there an easy way to convert a view-based app to a navigation-based app? I have an existing app sample that was created as a view-based app, and need to be able to create additional viewcontrollers that can be nested. The app is currently using presentModalViewController calls and nibs to display windows. Trying to change these to pushViewController calls results in the views not being displayed. So I'm assuming it's because the pushViewController needs to use a Navigation view. Thanks in advance!

  • Embedding an existing exe file into another program

    - by Milad
    Is there a way to link an existing .exe file with other C++ source files during compilation? What I'm actually trying to do is to compress and decompress some files in my console program using LZMA(7zip) SDK but unfortunately it's very difficult to use for a newbie. There is a command line version of LZMA called 7za.exe and I am wondering if I can somehow embed it into my program and use it like a function. It can be easily used with system() function (which seems to be a very dangerous thing to use) but then if I send my program to someone who doesn't have 7za.exe in the right folder it won't work. I came across CreateProcess() function in windows.h header files but it seems to achieve what system() does in a more proper and advanced way. I don't know if it can actually link the exe file like an object file during compilation

  • What do I use if a CSS framework or grid is bad?

    - by johnny
    Reference this question: http://stackoverflow.com/questions/203069/what-is-the-best-css-framework-and-are-they-worth-the-effort Do I go back to the "old" way of manually creating a template or downloading free ones again. For a little bit I thought a grid was the new thing and the best, now it appears I am wrong after all and not sure of best practice. And, yes, I can write my own CSS but didn't want to create the infrastructure if I didn't have to.

  • ASP.NET The underlying connection was closed: Could not establish trust relat

    - by David Lively
    When attempting to use HttpWebRequest to retrieve a page from my dev server, I get a web exception: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." The remote certificate is invalid according to the validation procedure... The url I'm attempting to read from is a plain-old http://myserver.com/mypage.asp - no SSL. The production server has a valid certificate so this shouldn't be an issue, but our dev server doesn't. Help!

  • TTCPServer limited to 10 connections?

    - by Stijn Sanders
    I've created a TCP server NT-Service in Delphi 6, I've tried Indy components, Ararat Synapse components, and am now trying just plain old TTcpServer to see which would perform best while using the least resources. I'm surprised to see that the live instance of the service (running on Windows Server) is still limited to 10 connections! Any new connections are forcibly disconnected. Have I missed something? Do I need to set a property or override a method of TCustomTcpServer?

  • Smartest way to draw 100+ images on screen

    - by Henrik
    Hello all, First of all I'm a newbie when it comes to Android programming. So if this question is totally stupid please delete it ASAP :-). Question: I'm going to draw a grid of 10x10 PNG images. Each image is 32x32 px. All of the images are unique. I'm thinking that the easiest way seems to be to put each image in an ImageView. If adding all ImageView's to the layout would this give me some kind of performance hit? Would there be any smarter way to draw these images? Thanks. / Henrik

    - by Tarzan
    A client of mine has an application written in Classic ASP and COM+. The managers are interested in migrating it to ASP.net MVC but they have to convince the CIO that it is a good move. The old app still works OK, other than the fact that no one at the company can maintain it. How can we sell upper management on converting to ASP.net from Classic ASP? Thanks in advance!

  • Blackberry Widget vs Java SDK

    - by rithanyalaxmi
    Hi, I am a newbie to this forum,I was going through the documents of both Blackberry Widget and Java SDK. I have the following doubts to get clarified:- 1) Advantages and disadvantages of Java SDK and Widget SDK? 2) When to go for Java SDK and Widget SDK? 3) Both Java and Widget applications require the latest blackberry OS 5.0? OR whether they are compatible with the lower versions as well? 4) Whatever developed with Java SDK can be done with widget SDK? similarly the vice-versa? 5) Is it possible to create the .java classes for Widget application development? 6) Whether all the blackberry models supports both Java and Widget ? 7) What are the Databases the blackberry Java and Widget supports? Please do shed some light into this as i was unable to find a suitable documentation on these. Thanks, Rithu

  • ebook reader for programming books?

    - by Martin
    Are the current ebook readers good enough for reading programming books (containing diagrams, source-code, screenshots, and so on)? How good are the search functions or the possibilities to set bookmarks, to use a book as a reference? I'd like to hear opinions of ebook reader owners to help me decide whether or not I should buy an ebook reader. (I know this question already exists, but it's over one year old and new ebook readers are now available)
