  • embedded web browser

    - by Ilya
    Hi, I'm looking for Linux embedded web browser, or preferably just a rendering object (it will not be used for actual browsing, just for displaying web based gui). The requirements are: Written in C (small footprint) Support Dynamic HTML Support Java script Minimum dependencies on the libraries (although i understand that it can not be completely standalone) No Dependency on X11 (i.e working with direct frame qui libraries) So far i only found Embedded Konqueror. Any suggestions are welcomed, commercial solutions are OK, but open source is preferable.

  • Help with C# program design implementation: multiple array of lists or a better way?

    - by Bob
    I'm creating a 2D tile-based RPG in XNA and am in the initial design phase. I was thinking of how I want my tile engine to work and came up with a rough sketch. Basically I want a grid of tiles, but at each tile location I want to be able to add more than one tile and have an offset. I'd like this so that I could do something like add individual trees on the world map to give more flair. Or set bottles on a bar in some town without having to draw a bunch of different bar tiles with varying bottles. But maybe my reach is greater than my grasp. I went to implement the idea and had something like this in my Map object: List<Tile>[,] Grid; But then I thought about it. Let's say I had a world map of 200x200, which would actually be pretty small as far as RPGs go. That would amount to 40,000 Lists. To my mind I think there has to be a better way. Now this IS pre-mature optimization. I don't know if the way I happen to design my maps and game will be able to handle this, but it seems needlessly inefficient and something that could creep up if my game gets more complex. One idea I have is to make the offset and the multiple tiles optional so that I'm only paying for them when needed. But I'm not sure how I'd do this. A multiple array of objects? object[,] Grid; So here's my criteria: A 2D grid of tile locations Each tile location has a minimum of 1 tile, but can optionally have more Each extra tile can optionally have an x and y offset for pinpoint placement Can anyone help with some ideas for implementing such a design (don't need it done for me, just ideas) while keeping memory usage to a minimum? If you need more background here's roughly what my Map and Tile objects amount to: public struct Map { public Texture2D Texture; public List<Rectangle> Sources; //Source Rectangles for where in Texture to get the sprite public List<Tile>[,] Grid; } public struct Tile { public int Index; //Where in Sources to find the source Rectangle public int X, Y; //Optional offsets }

  • What are my best ASP.Net GridView replacement options?

    - by Homer
    We currently use a GridView to display 1000+ rows of data. Minimum requirement for replacement is a fixed header row, fixed footer and columns would be a plus. This would have to work across IE 6 and greater. I've heard good things about Infragistics, but the demo on their page is slow. So what are my best options? jQuery? YUI? other 3rd party?

  • optimizing any OS for maximum informix client/server performance

    - by Frank Developer
    Is there any Informix documentation for optimizing any operating system where an ifx engine is running? For example, in Linux, strip-down to a bare minimum all unnecessary binaries, daemons, utilities, tune kernel parameters, optimize raw and cooked devices (hdparm), place swap space on beginning tracks of a disk, etc. Someday, maybe, Informix can create its own proprietary and dedicated PICK-like O/S to provide the most optimized environment for a standalone ifx server? The general idea is for the OS where ifx sits on have the smallest footprint and lowest overhead impact.

  • C# Microsoft LifeCam HD mjpeg capture

    - by IraqiGeek
    Hi, I have a Microsoft LifeCam HD-5000 webcams. According to AMCap, the camera outputs a MJPEG stream at 30fps at 720p. I want to capture each JPEG frame in a small application without doing any preview or decompression/transcoding to minimize CPU utilization to the minimum possible. I'm a C# developer, but I'm new to DirectShow. Is there a simple way to capture the MJPEG stream frame by frame as its output from the camera in C#/.NET without decompressing it?

  • Android browser scaling?

    - by Joren
    I'm trying to create a mobile website for android. When I set the width of the body to 480px (the width of the screen) the result is about 50% larger than what I expect. It seems that android is scaling what it draws and messing up all my layouts. Does anyone know how to disable this, or work around it? I'm already using this: <meta name="viewport" content="width=device-width, height=device-height, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0" />

  • RSA key length and export limitations

    - by Alex Stamper
    I know, there are a lot of limitations to the length of used key (import and export limitations for nearly each country). Usually, it varies from 64 to 256 bits. To use more bits, it is obligatory to ask permission from authorities. But it is recommended to use 1024 bits keys for RSA as minimum! Does it mean that I cannot just use RSA without any problems with law and so on?

  • How do I 'globally' catch exceptions thrown in object instances.

    - by SleepyBobos
    I am currently writing a winforms application (C#). I am making use of the Enterprise Library Exception Handling Block, following a fairly standard approach from what I can see. IE : In the Main method of Program.cs I have wired up event handler to Application.ThreadException event etc. This approach works well and handles the applications exceptional circumstances. In one of my business objects I throw various exceptions in the Set accessor of one of the objects properties set { if (value > MaximumTrim) throw new CustomExceptions.InvalidTrimValue("The value of the minimum trim..."); if (!availableSubMasterWidthSatisfiesAllPatterns(value)) throw new CustomExceptions.InvalidTrimValue("Another message..."); _minimumTrim = value; } My logic for this approach (without turning this into a 'when to throw exceptions' discussion) is simply that the business objects are responsible for checking business rule constraints and throwing an exception that can bubble up and be caught as required. It should be noted that in the UI of my application I do explictly check the values that the public property is being set to (and take action there displaying friendly dialog etc) but with throwing the exception I am also covering the situation where my business object may not be used by a UI eg : the Property is being set by another business object for example. Anyway I think you all get the idea. My issue is that these exceptions are not being caught by the handler wired up to Application.ThreadException and I don't understand why. From other reading I have done the Application.ThreadException event and it handler "... catches any exception that occurs on the main GUI thread". Are the exceptions being raised in my business object not in this thread? I have not created any new threads. I can get the approach to work if I update the code as follows, explicity calling the event handler that is wired to Application.ThreadException. This is the approach outlined in Enterprise Library samples. However this approach requires me to wrap any exceptions thrown in a try catch, something I was trying to avoid by using a 'global' handler to start with. try { if (value > MaximumTrim) throw new CustomExceptions.InvalidTrimValue("The value of the minimum..."); if (!availableSubMasterWidthSatisfiesAllPatterns(value)) throw new CustomExceptions.InvalidTrimValue("Another message"); _minimumTrim = value; } catch (Exception ex) { Program.ThreadExceptionHandler.ProcessUnhandledException(ex); } I have also investigated using wiring a handler up to AppDomain.UnhandledException event but this does not catch the exceptions either. I would be good if someone could explain to me why my exceptions are not being caught by my global exception handler in the first code sample. Is there another approach I am missing or am I stuck with wrapping code in try catch, shown above, as required?

  • Getting max. screen resolution with Group By

    - by Quandary
    Question: I have a website where I gather browser statistics. I have an SQL table (T_Visits), with the following columns: uniqueidentifier Visit_UID, uniqueidentifier User_UID, datetime Visit_DateTime, float Screen_w, float Screen_h, float Resolution = Screen_w * Screen_h varchar resolutionstring = screen_w + ' x ' + screen_h Now I want to get the maximum/minimum resolution each user had: Select User_UID, max(resolution) from T_Visits GROUP BY User_UID How can I get the corresponding resolution string ? I mean I can get the max(screen_w) and max(screen_h), but there's no guarantee that the corresponding resolutionstring would be max(screen_w) +' x '+ max(screen_h)

  • What are the requirments for ISupportInitialize code to be serialized in InitializeComponent? .Net

    - by Jules
    I need to add some code to the EndInit method of a PictureBox control but unfortunately its private and, from what I can gather, I can't shadow it and call base - at least not in VB.Net. What I can do is add a dummy property to my picture box class. The type of the dummy property is simply a class that just implements ISupportInitialize. However, that doesn't work, I need the dummy class to inherit from Control. Is that the minimum requirement?

  • Ruby 1.9 and Rackspace's email api (SOAP)

    - by kjs3
    Is anyone out there working with SOAP on Ruby 1.9? Rackspace has email addresses for $2/month and an api to programmatically create/destroy accounts which looks like the best I've found. Fusemail has $2 addresses too but you need a minimum of 80 to get access to the api. So, I either need to find a solution to working with Rackspace or a different email host.

  • Calculate business days

    - by AdamTheHutt
    Hi, I need a method for adding "business days" in PHP. For example, Friday 12/5 + 3 business days = Wednesday 12/10. At a minimum I need the code to understand weekends, but ideally it should account for US federal holidays as well. I'm sure I could come up with a solution by brute force if necessary, but I'm hoping there's a more elegant approach out there. Anyone? Thanks.

  • encryption of a single character

    - by SystemicPlural
    What is the minimum number of bits needed to represent a single character of encrypted text. eg, if I wanted to encrypt the letter 'a', how many bits would I require. (assume there are many singly encrypted characters using the same key.) Am I right in thinking that it would be the size of the key. eg 256 bits?
