    - by Lynx
    here is the code for JockerSoft.Media // Path of the video and frame storing path string _videopath = "http://www.test.com/Video/test.avi"; //"C:\\test.avi"; string _imagepath = "C:\\test.jpg" Bitmap bmp = FrameGrabber.GetFrameFromVideo(_videopath, 0.1d); bmp.Save(_imagepath, System.Drawing.Imaging.ImageFormat.Gif); // Save directly frame on specified location FrameGrabber.SaveFrameFromVideo(_videopath, 0.1d, _imagepath); it work perfectly is the video file is from my own computer, but when i try to get video file from remote location it not getting the frame. well, all the example is for windwos form app and i trying to use this for web-application. is there maybe an additional coding that enable me to use jockersoft to grab a video frame from remote location? here is the error that i got: Attempted to access an unloaded appdomain.

  • How do I hook into a game and write a script to manipulate it?

    - by Ethan
    Hey SO, I know this is a pretty open question but I was wondering how people go about writing scripts that will "play" a game, or manipulate it in some way. I had been thinking that I'd try to get a working AI to play a game for fun, but don't even really know where to start. Are there any good resources to learn this? What are good languages to use? Once I have the language, how do I get my script hooked into the game? I was thinking of just trying simple flash games, if that helps. Thanks a bunch!

  • Is it possible to write a database view that encompasses one-to-many relationships?

    - by Brandon Linton
    So I'm not necessarily saying this is even a good idea if it were possible, since the schema of the view would be extremely volatile, but is there any way to represent a has-many relationship in a single view? For example, let's say I have a customer that can have any number of addresses in the database. Is there any way to list out each column of each address with perhaps a number as a part of the alias (e.g., columns like Customer Id, Name, Address_Street_1, Address_Street_2, etc)? Thanks!

  • Chicken and egg problem (restore database) when trying to write unit test against SQl Server 2008.

    - by Hamish Grubijan
    Ok, they are not unit tests but end-to-end tests. The setup is somewhat involved. Unit tests will use C#, ODBC connection. Every unit tests will try to clean up after itself, but every 20 tests or so (once per C# class) we would need to do a full database restore. I do not think I can do it over an ODBC connection, according to this document: http://www.sql-server-performance.com/articles/dba/Obtain_Exclusive_Access_to_Restore_SQL_Server_p1.aspx Msg 6104, Level 16, State 1, Line 1 Cannot use KILL to kill your own process. However, I would like to, so that 199 tests do not go amok because of a bad clean-up. Is there another way? Perhaps I can open a different "connection" such as use COM automation or something of that sort, and then kill all database connections from there? If so, how can I do that? Also, will the clients be able to re-connect automatically after a restore, or would I have to dismantle everything once every 20 tests or so? If you find this question confusing, please let me know what your questions are. Thanks!

  • Which technology(s) / language(s) to write linux web application/service? [closed]

    - by Lee Tickett
    I am currently playing with some open source home automation software www.domotiga.nl The software is built in Gambas2 (a graphical programming language similar to visual basic). I am considering building something similar or porting domotiga to a server based application/service. The application would need a web front end and i will likely be developing in debian (arm). But i'm not sure if php or python are suitable for server based applications which need to be always running (collecting data etc) rather than just running when accessed. Which technology(s) / language(s) would you suggest i look into? I used to do a lot of Visual Basic, then VB.NET, now C# and have played with php a few years back- but don't really want this to sway the decision too much as i should be able to pickup whatever language if i decide to proceed.

  • How to write a "thread safe" function in C ?

    - by Andrei Ciobanu
    Hello I am writing some data structures in C, and I've realized that their associated functions aren't thread safe. The i am writing code uses only standard C, and I want to achieve some sort of 'synchronization'. I was thinking to do something like this: enum sync_e { TRUE, FALSE }; typedef enum sync_e sync; struct list_s { //Other stuff struct list_node_s *head; struct list_node_s *tail; enum sync_e locked; }; typedef struct list_s list; , to include a "boolean" field in the list structure that indicates the structures state: locked, unlocked. For example an insertion function will be rewritten this way: int list_insert_next(list* l, list_node *e, int x){ while(l->locked == TRUE){ /* Wait */ } l->locked = TRUE; /* Insert element */ /* -------------- */ l->locked = FALSE; return (0); } While operating on the list the 'locked' field will be set to TRUE, not allowing any other alterations. After operation completes the 'locked' field will be again set to 'TRUE'. Is this approach good ? Do you know other approaches (using only standard C).

  • Is there a better loop I could write to reduce database queries?

    - by dmanexe
    Below is some code I've written that is effective, but makes too many database queries. Is there a way I could optimize and reduce the number of queries but have conditional statements still be as effective as below? I pasted the code repeated a few times just for good measure. echo "<h3>Pool Packages</h3>"; echo "<ul>"; foreach ($items as $item): $this->db->where('id', $item['id']); $query = $this->db->get('items')->row(); if ($item['quantity'] > 1 && $item['quantity'] == TRUE && $query->category == "Pool Packages") { $newprice = $item['quantity'] * $query->price; $totals[] = $newprice; } else { $newprice = $query->price; $totals[] = $newprice; } if ($query->category == "Pool Packages") { echo "<li>" . $query->name .

  • How to increment the string value during run time without using dr.read() and store it in the oledb

    - by sameer
    Here is my code, everything is working fine the only problem is with the ReadData() method in which i want the string value to be increment i.e AM0001,AM0002,AM0003 etc. This is happening but only one time the value is getting increment to AM0001, the second time the same value i.e AM0001 is getting return. Due to this i am getting a error from oledb because of AM0001 is a primary key field. enter code here: class Jewellery : Connectionstr { string lmcode = null; public string LM_code { get { return lmcode;} set { lmcode = ReadData();} } string mname; public string M_Name { get { return mname; } set { mname = value;} } string desc; public string Desc { get { return desc; } set { desc = value; } } public string ReadData() { string jid = string.Empty; string displayString = string.Empty; String query = "select max(LM_code)from Master_Accounts"; Datamanager.RunExecuteReader(Constr,query); if (string.IsNullOrEmpty(jid)) { jid = "AM0000";//This string value has to increment at every time, but it is getting increment only one time. } int len = jid.Length; string split = jid.Substring(2, len - 2); int num = Convert.ToInt32(split); num++; displayString = jid.Substring(0, 2) + num.ToString("0000"); return displayString; } public void add() { String query ="insert into Master_Accounts values ('" + LM_code + "','" + M_Name + "','" + Desc + "')"; Datamanager.RunExecuteNonQuery(Constr , query); } Any help will be appreciated.

  • How can I have a Windows 7 VMware guest without mouse support?

    - by Matthew Read
    Despite having vmmouse.present = "FALSE" mouse.vusb.absDisabled = "TRUE" pref.motionUngrab = "FALSE" in my .vmx file and a customized VMware Tools installation on the guest that does not include the mouse driver, I somehow have fully integrated mouse support for my Windows 7 VM. I can smoothly mouse from the host into the guest without needing to click or Ctrl+G in and Ctrl+Alt out. I don't want this because of the issues it causes with games. How can I get the VM to have no special mouse support while still having VMware Tools installed for its other functions (network, graphics, etc.)? The mouse works as I want without VMware Tools but not otherwise — again, despite not installing the mouse driver and having all those settings trying to disable it. Device Manager shows that the generic Windows PS/2 mouse driver is being used and not the virtual mouse driver. Guest and host are both Windows 7 Ultimate SP1, x86 and x64 respectively. I'm using VMware Player 3.1.4 and the VMware Tools installed is the latest, 8.4.6.16648.

  • Can knowing C actually hurt the code you write in higher level languages?

    - by Jurily
    The question seems settled, beaten to death even. Smart people have said smart things on the subject. To be a really good programmer, you need to know C. Or do you? I was enlightened twice this week. The first one made me realize that my assumptions don't go further than my knowledge behind them, and given the complexity of software running on my machine, that's almost non-existent. But what really drove it home was this Slashdot comment: The end result is that I notice the many naive ways in which traditional C "bare metal" programmers assume that higher level languages are implemented. They make bad "optimization" decisions in projects they influence, because they have no idea how a compiler works or how different a good runtime system may be from the naive macro-assembler model they understand. Then it hit me: C is just one more abstraction, like all others. Even the CPU itself is only an abstraction! I've just never seen it break, because I don't have the tools to measure it. I'm confused. Has my mind been mutilated beyond recovery, like Dijkstra said about BASIC? Am I living in a constant state of premature optimization? Is there hope for me, now that I realized I know nothing about anything? Is there anything to know, even? And why is it so fascinating, that everything I've written in the last five years might have been fundamentally wrong? To sum it up: is there any value in knowing more than the API docs tell me? EDIT: Made CW. Of course this also means now you must post examples of the interpreter/runtime optimizing better than we do :)

  • What are the books about Open-Source that everyone interested in should read?

    - by Edu Zamora
    Currently I am working and running my first Open-Source project and though I am quite happy how things are working so far, I have the feeling that a lot of things could be done better. So, what books about Open-Source would you recommend me in order to help filling this gap and making things better every day? What are the books that influenced you the most? I am especially interested in: - How to organize and run an Open-Source project - Best practices - Manage and involve users and developers - How to announce and do the releases - Legal issues
