  • How do I play a video through .net in windows 7

    - by Mykroft
    I had setup an app to play a video using the library suggested here this worked great for me for a long time until my machine was upgraded. In windows 7 I get the following exception that I'd never seen under XP: `System.BadImageFormatException: is not a valid Win32 application. (Exception from HRESULT: 0x800700C1) at MainApp.Controls.MediaControl.StopVideo() at System.Windows.Forms.Form.WmClose(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)` I've installed the June 2010 DirectX SDK and I'm still getting this error. Is there a different library I should be using or some setting that needs to be changed?

  • Controlling a browser from Python

    - by Noio
    I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

  • What notes should I be taking, if any, at the beginning of a project?

    - by Justin R.
    I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

  • Write Local File using Adobe Air Iframe

    - by user290687
    This is driving me mad. I am creating an AIR application and everything is working great. However I would really like to have a form inside an Iframe that when the user clicks submit saves the file to local application storage directory. Right now I am able to do this and save the file with no problems when I just access the HTML page not inside an Iframe. However if I wrap the page in an iframe and hit submit the file does not save. Any code examples would be very much appreciated. When I am using the iframe my code looks as follows<iframe src="jobs/newjob.html" height="800px" width="800px" sandboxRoot="app:/" documentRoot="app:/sandbox"ondominitialize="setupBridge ()">

  • Do you use a grid system when designing a web page?

    - by johnny
    I'm trying to figure out why I would use a grid system. I have read some but I just don't get it. I'm used to just putting stuff in html on a page and beind done with it but I have a new project and would like to use a grid because apparently it is a best practice. I read in one article referenced in another SO question and it said that grid design was in all sorts of development, even application form design. That made me think of things like snap to grid, etc. and I didn't know if the grid in the web design sphere was the same. I was hoping someone could give me a brief but not overly complicated view and not a link to Google which I have used already. Thank you for any help.

  • grayscaling images and refering the original image back.

    - by dilip
    I know how to grayscale an image. I am using jquery accordion and I have images on every accordion header. I want to change the image to grayscale when the accordion is active and change the image back to its original form when the accordion is not active. I am using the event accordionChange. The problem is that I am not able to save the original image. Please help. Also after grayscaling I tried to give the original src directly as document.getElementById("imgId").src = "images/pic.jpg"; This is not working.

  • drupal hook just before inserting/updating user info

    - by Senthil
    Hi, I want to hook into drupal's user registration and be able to stop it or allow it to proceed just before database insert. All validations and 3rd party stuff must be done and just before inserting I need to hook in. What is the hook and the operation to do this? I tried 'validate' operation in the hook_user. But, after I check against my logic and let the registration proceed, it should not fail due to some other validation. If I let it proceed, no application logic after that should stop the registration (unless the DB engine fails or something of course). If I stop it, I will set a form error so that nothing happens. How can this be accomplished? P.S. I am using Drupal 6.16

  • "Socket operation on non-socket" error due to strange sytax

    - by Robert S. Barnes
    I ran across the error Socket operation on non-socket in some of my networking code when calling connect and spent a lot of time trying to figure out what was causing it. I finally figured out that the following line of code was causing the problem: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol) < 0)) { See the problem? Here's what the line should look like: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol)) < 0) { What I don't understand is why the first, incorrect line doesn't produce a warning. To put it another way, shouldn't the general form: if ( foo = bar() < baz ) do_somthing(); look odd to the compiler, especially running with g++ -Wall -Wextra? If not, shouldn't it at least show up as "bad style" to cppcheck, which I'm also running as part of my compile?

  • jQuery: how to find first visible input/select/textarea excluding buttons?

    - by Artem
    I tried $(":input:not(input[type=button],input[type=submit],button):visible:first") but it doesn't find anything. What is my mistake? UPD: I execute this on $(document).load() <script type="text/javascript"> $(window).load(function () { var aspForm = $("form#aspnetForm"); var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm); firstInput.focus(); }); </script> and in the debug I can see that firstInput is empty. UPD2: I'm in ASP.NET page running under Sharepoint. I've found so far that for some elements it does find them (for fixed ones) and for some don't. :(

  • Selecting data from mysql table and related data from another to join them

    - by knittledan
    Ive looked at other questions and answers but still dont understand which brings me here. I have one data base two tables. lets say table1 and table2 from database. I'm looking to grab all the information from table1 and only one column from table2 that coincides with the correct row in table1. Example which I know is wrong: SELECT table1.*, table2.time_stamp FROM table1, table2 WHERE table1.ticket_id=$var AND table1.user_id = table2.user_id Basically select data from table1 then use a value from the selected table to grab the related data from table2 and join them to output them as one mysql_query. Im sure its simple and has been asked before. edit: I dont receive an error. SQL just returns noting. log form of this would be: $sqlResults = mysql_query("SELECT table1.* FROM table1 WHERE table1.ticket_id=$var") while($rowResult = mysql_fetch_array( $sqlResults )) { $userID = $rowResult['user_id']; $sqlResults2 = mysql_query("SELECT table2.time_stamp FROM table2 WHERE table2.user_id=$userID") } I want to combine that into one sql statement so i dont have to hit table2 for every row table1 has

  • MVC - Sanitizing data, where?

    - by dierre
    I'm using CakePHP but it's a question about the MVC pattern. I have in my form the input-text for the tags (separated by commas). To add the tags I've created a Tag model method that basically check if the tag exists and then add the new tag or just a new unit in the tag counter (the Tag model has these fields: id, name, slug, count). In the controller I explode the tags field and pass one tag at a time. The question is: where do I sanitize data? In the controller or in the model method? I think it should be in the controller because that's where I explode but in term of reusability I think I should sanitize data in the model. What do you think?

  • VB.NET - cannot get Video Preview to work

    - by Yiu Korochko
    Hi, Overflow. I have an application which is supposed to convert a video via DirectShowSource. I have a checkbox which enables a button called "btnviewcrop" which shows a new form called crp.vb for cropping/shearing pixels off the video. Now, I have a Panel1 that I want to set as the owner (the video drawing surface) but when I set it to open, the application crashes (Error: Object reference not set to an instance of an object.) and I do not understand how to fix it. Here is my button code: Imports Microsoft.DirectX.AudioVideoPlayback Private Sub btnviewcrop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnviewcrop.Click Me.ShowInTaskbar = False Me.Enabled = False crp.Show() Dim cropperv As Video cropperv.Owner = crp.preview cropperv.FromFile(labinputfile.Text, True) cropperv.Play() End Sub

  • PHP - Using strcpsn() to protect against SQL injection?

    - by MichaelMitchell
    I am making a sort of form validation system and I need to check the SQL database to see if the username is already there. So, my question, is it effective to use a little if statement like this to protect against an attack? if (strcspn($string, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=" == strlen($string)){ return true; } So essentially, if the string contains any of these characters, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=", then the length will not equal that of the original $string. I am just wondering if this is sufficient to protect, or if there is more that I must do. Thanks.

    I am starting a process lets say abc.exe in a background worker. In the begining everything works fine but in between the newly created process i.e. abc.exe haults. Although I am starting abc.exe as hidden window but I come to know about its hang as it stopes doing log writing. When I close my UI form then again abc.exe starts working. Can anybody tell me what could be the possible cause for this? I am not able to debug the issue as it can happen at any time, I can not replicate it. Please tell me as it is very urgent for me. If some more info is required then please revert back.

  • Implementation Details as a "Document" ( In generic terms) - Python, C++

    - by mgj
    Hi..:) For documentation and presentation purposes, we often find professionals/students creating SRS, coding guidelines etc. for these things there is some kind of a checklist which one could use to appropriately match what could relate to a specific case and accordingly one does a documentation for each. On those grounds could you please give me some sort of a checklist( any points/guidelines) one could use for going about Implementation( in the form of Implementation Details) in Python and C++ . Although this might sound specific as the query is "Implementation Details" and is different for different cases as one goes about the REAL implementation, I just want a SET of guidelines one should follow ( Preferably In Python, C++ specific, even for any other language is Welcome) if this( Implementation Details ) has to also be documented or presented. Hope the question is clear, I am sorry if it still sounds ambiguous, I guess this is the best I could do to frame my query. Thank you for your time...:)

  • Parsing a string representing a float *with an exponent* in Python

    - by Lucas
    Hi, I have a large file with numbers in the form of 6,52353753563E-7. So there's an exponent in that string. float() dies on this. While I could write custom code to pre-process the string into something float() can eat, I'm looking for the pythonic way of converting these into a float (something like a format string passed somewhere). I must say I'm surprised float() can't handle strings with such an exponent, this is pretty common stuff. I'm using python 2.6, but 3.1 is an option if need be.

  • set up way of getting mysite.$domain

    - by jose silva
    Hi I have several domains, only one website and one databse table for each domain. example: wbesite.us - data from USA goes to database table main_usa wbesite.co.uk - data form UK goes to database table main_uk Only have one database with name of the website. Having only one website structured, and having variables like $sql="select * from main_".$countrycode." where bla..bla..., and many other variables to catch the domain extension, and so on... Now, instead of having one full website for each domain, how can set a script and wher do I put it in order to detect the domain that the user uses. In my server root do I create something like website.$domain ? Something like website OLX but for different purposes. I hope I made myself clear. Thank you.

  • C# - High Quality Byte Array Conversion of Images

    - by Lijo
    Hi Team, I am converting images to byte array and storing in a text file using the following code. I am retrieving them successfully as well. My concern is that the quality of the retrieved image is not up to the expectation. Is there a way to have better conversion to byte array and retrieving? I am not worried about the space conception. Please share your thoughts. string plaintextStoringLocation = @"D:\ImageSource\Cha5.txt"; string bmpSourceLocation = @"D:\ImageSource\Cha50.bmp"; ////Read image Image sourceImg = Image.FromFile(bmpSourceLocation); ////Convert to Byte[] byte[] clearByteArray = ImageToByteArray(sourceImg); ////Store it for future use (in plain text form) StoreToLocation(clearByteArray, plaintextStoringLocation); //Read from binary byte[] retirevedImageBytes = ReadByteArrayFromFile(plaintextStoringLocation); //Retrieve from Byte[] Image destinationImg = ByteArrayToImage(retirevedImageBytes); //Display Image pictureBox1.Image = destinationImg; Thanks Lijo

    My table is as follows ObjectID bigint Tag nvarchar(50) Weight float Type tinyint I want to get search for all objects that has tags 'big' or 'large' I want the objectid in order of sum of weights (so objects having both the tags will be on top) select objectid, row_number() over (order by sum(weight) desc) as rowid from tags where tag in ('big', 'large') and type=0 group by objectid the reason for row_number() is that i want paging over results. The query in its current form is very slow, takes a minute to execute over 16 million tags. What should I do to make it faster? I have a non clustered index (objectid, tag, type) Any suggestions?

  • How To Find the Control or Page a User Control is Embedded In

    - by 5arx
    I've written a web user control which I want to be able to drop into the markup for either aspx pages or other web user controls. I need my user control to be able to easily and efficiently work out if its inside another user control or an aspx page. My initial idea is to do it recursively with checks on the Parent property - continue looking up the nesting hierarchy until I find either a web form or a user control - but I'm not sure this the best way of going about this. Can you suggest an easier way? thanks 5arx
