  • How would one rotate an image around itself using Canvas?

    - by Wolfr
    I'm having trouble roating an image around itself using Canvas. Since you can't rotate an image you have to rotate the canvas: if I rotate the canvas by a degree the origin around which I want to rotate changes. I don't get how to track this change. This is my current code: http://pastie.org/669023 And a demo is at http://preview.netlashproject.be/cog/ If you want to give things a shot the zipped up code and image is at http://preview.netlashproject.be/cog/cog.zip

  • AST generation for a an application developed both in visual basic and c#

    - by Dev
    Hi, I'm currently understanding one application developed both in visual basic and c#. Running through the code is getting tough as code is around 50KLOC. So i'm planning for generation of AST (abstract syntax tree). Will it be possible to generate for both language together. Atleast a call graph generation will be helpful (but can't find any tool which works for both languages) Please let me know if this question is confusing. Thanks in Advance Dev

  • using win32 api in linux ?

    - by Dr Deo
    I have heard of WINE but I don't like it because it's slow on the computers I have tested and almost always crashes. It also has some unpleasant looking gui. I am wondering if there is a "win32" library in c/c++ for linux that produces native linux code so that if I have my source code for windows, I can just recompile and produce a working linux application. Is this possible?

  • Delphi - Read File To StringList, then delete and write back to file.

    - by Jkraw90
    I'm currently working on a program to generate the hashes of files, in Delphi 2010. As part of this I have a option to create User Presets, e.g. pre-defined choice of hashing algo's which the user can create/save/delete. I have the create and load code working fine. It uses a ComboBox and loads from a file "fhpre.ini", inside this file is the users presets stored in format of:- PresetName PresetCode (a 12 digit string using 0 for don't hash and 1 for do) On application loading it loads the data from this file into the ComboBox and an Array with the ItemIndex of ComboBox matching the corrisponding correct string of 0's and 1's in the Array. Now I need to implement a feature to have the user delete a preset from the list. So far my code is as follows, procedure TForm1.Panel23Click(Sender : TObject); var fil : textfile; contents : TStringList; x,i : integer; filline : ansistring; filestream : TFileStream; begin //Start Procedure //Load data into StringList contents := TStringList.Create; fileStream := TFileStream.Create((GetAppData+'\RFA\fhpre.ini'), fmShareDenyNone); Contents.LoadFromStream(fileStream); fileStream.Destroy(); //Search for relevant Preset i := 0; if ComboBox4.Text <> Contents[i] then begin Repeat i := i + 1; Until ComboBox4.Text = Contents[i]; end; contents.Delete(i); //Delete Relevant Preset Name contents.Delete(i); //Delete Preset Digit String //Write StringList back to file. AssignFile(fil,(GetAppData+'\RFA\fhpre.ini')); ReWrite(fil); for i := 0 to Contents.Count -1 do WriteLn(Contents[i]); CloseFile(fil); Contents.Free; end; However if this is run, I get a 105 error when it gets to the WriteLn section. I'm aware that the code isn't great, for example doesn't have checks for presets with same name, but that will come, I want to get the base code working first then can tweak and add extra checks etc. Any help would be appreciated.

  • In C#, What is <T> After a Method Declaration?

    - by Drew
    I'm a VB.Net guy. (because I have to be, because the person who signs my check says so. :P) I grew up in Java and I don't generally struggle to read or write in C# when I get the chance. I came across some syntax today that I have never seen, and that I can't seem to figure out. In the following method declaration, what does < T represent? static void Foo < T (params T[] x) I have seen used in conjunction with declaring generic collections and things, but I can't for the life of me figure out what it does for this method. In case it matters, I came across it when thinking about some C# brain teasers. The sixth teaser contains the entire code snippet.

  • Writing a Python extension in Go (golang)

    - by tehwalrus
    I currently use Cython to link C and Python, and get speedup in slow bits of python code. However, I'd like to use go routines to implement a really slow (and very parallelizable) bit of code, but it must be callable from python. (I've already seen this question) I'm (sort of) happy to go via C (or Cython) to set up data structures etc if necessary, but avoiding this extra layer would be good from a bug fix/avoidance point of view. What is the simplest way to do this without having to reinvent any wheels?

  • Create a new output file in ant replace task

    - by Sathish
    Ant replace task does a in-place replacement without creating a new file. The below snippet replaces tokens in any of the *.xml files with the corresponding values from my.properties file. <replace dir="${projects.prj.dir}/config" replacefilterfile="${projects.prj.dir}/my.properties" includes="*.xml" summary="true"/'> I want those *.xml files that had their tokens replaced be created as *.xml.filtered (for e.g.) and still have the original *.xml. Is this possible in Ant with some smart combination of tasks and concepts ?

  • How to scan for available networks for Blackberry device from application?

    - by amsiddh
    Hi All, Is there any RIM API available which will help to get the list of available network service or only Wi-Fi networks for a device and set selected network access point for any network communications? Is it possible programmatically to disable the Mobile networks like GPRS, WAP, etc? For Ex: When a application is started it should scan for WiFi connections (even if there are no previous WiFi network access points are set on device) and list the available WiFi connection. Then user will select the appropriate WiFi connection to connect for any network communication. Outside the application any internet communication (like browser or any other application) should done through same selected WiFi connection. The scanning for WiFi and setting the connection is almost similar to Blackberry WiFi Setup. If anyone know how to implement this using available RIM API and let me know its possible or not. Please share if anyone have any code snippet related to this. I am looking for OS v4.5, 4.7, and 5.0. Thanks, siddh.

  • How to find scrollable elements in DOM using XPath?

    - by ak.
    Basically I need to find all elements on the page that have a scrollbar (vertical or horizontal) How to tell if an element has a scrollbar and can actually be scrolled? I found this code snippet on jsperf. Is it possible to capture the logic behind the code into and XPath expression? Or are there any other ways to check for scrollbars? Added: Just to explain what I'm trying to do: I'm developing extension for Firefox. Basically it introduces Vim-style mouseless shortcuts (I know there is Vimperator and Pentadactyl...). One of the features I'd like to implement is to allow the use to select the container that's scrolled with j/k keys. That's why I need to discover all scrollable elements on any given random page.

  • jquery plugins for truncating long text string by container width/height

    - by ShiVik
    Hello all As the title says, I want to truncate user-input text string based on the width and height of a designated container. My specification is to truncate the string, display some message like Read More at the end and when user clicks on it, the text slides down. UPDATE: Ah! Forgot one thing. It should handle multi-byte characters as well. Can somebody throw some light on what options do I have? jQuery plugins or some nifty jquery snippet? Thanks and Regards
