  • Should I implement IDisposable here?

    - by dotnetdev
    My method which calls SQL Server returns a datareader but because of what I need to do (return the datareader to the calling method which is in page code-behind), I can't close the connection in the class of the method which calls sql server, so I have no finally or using blocks. Is the correct way of disposing resources to make the class implement IDisposable? Or from the caller, explicitly dispose the unmanged resource (class-level fields)? Thanks

  • Do we still need backup code for people who have javascript disabled?

    - by SLC
    I hear about it a bit in tutorials that I watch, that certain things won't work if javascript is disabled. Occasionally I see workarounds. The question is, are these relevent? I can't imagine anyone not having a javascript enabled browser nowadays, except the most ancient of phones, and chances are your page won't render on them properly anyway. Do people still bother to write backup code for javascript being disabled?

  • Display BLOB (image) through JSP

    - by jMarcel
    I have a code to show a chart o employees. The data (name, phone, photo etc) are stored in SQLServer and displayed through JSP. Showing the data is ok, except the image .jpg (stored in IMAGE=BLOB column). By the way, I've already got the image displayed (see code below), but I dont't know how to put it in the area defined in a .css (see code below, too), since the image got through the resultSet is loaded in the whole page in the browser. Does anyone knows how can I 'frame' the image ? <% Connection con = FactoryConnection_SQL_SERVER.getConnection("empCHART"); Statement stSuper = con.createStatement(); Statement stSetor = con.createStatement(); Blob image = null; byte[] imgData = null; ResultSet rsSuper = stSuper.executeQuery("SELECT * FROM funChart WHERE dept = 'myDept'"); if (rsSuper.next()) { image = rsSuper.getBlob(12); imgData = image.getBytes(1, (int) image.length()); response.setContentType("image/gif"); OutputStream o = response.getOutputStream(); //o.write(imgData); // even here we got the same as below. //o.flush(); //o.close(); --[...] <table style="margin: 0px; margin-top: 15px;"> <tr> <td id="photo"> <img title="<%=rsSuper.getString("empName").trim()%>" src="<%= o.wite(imageData); o.flush(); o.close(); %>" /> </td> </td> <td id="empData"> <h3><%=rsSuper.getString("empName")%></h3> <p><%=rsSuper.getString("Position")%></p> <p>Id:<br/><%=rsSuper.getString("id")%></p> <p>Phone:<br/><%=rsSuper.getString("Phone")%></p> <p>E-Mail:<br/><%=rsSuper.getString("Email")%></p> </td> </table> And here is the fragment supposed to frame the image: #photo { padding: 0px; vertical-align: middle; text-align: center; width: 170px; height: 220px; } Thanks in advance !

  • How to detect invalid image URL with JAVA?

    - by Cataclysm
    I have a method to download image from URL. As like below.. public static byte[] downloadImageFromURL(final String strUrl) { InputStream in; ByteArrayOutputStream out = new ByteArrayOutputStream(); try { URL url = new URL(strUrl); in = new BufferedInputStream(url.openStream()); byte[] buf = new byte[2048]; int n = 0; while (-1 != (n = in.read(buf))) { out.write(buf, 0, n); } out.close(); in.close(); } catch (IOException e) { return null; } return out.toByteArray(); } I have an image url and it is valid. for example. https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTxfYM-hnD-Z80tgWdIgQKchKe-MXVUfTpCw1R5KkfJlbRbgr3Zcg My problem is I don't want to download if image is really not exists.Like .... https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcTxfYM-hnD-Z80tgWdIgQKchKe-MXVUfTpCw1R5KkfJlbRbgr3Zcgaaaaabbbbdddddddddddddddddddddddddddd This image shouldn't be download by my method. So , how can I know the giving image URL is not really exists. I don't want to validate my URL (I think that may not my solution ). So, I googled for that. From this article ... How to check if a URL exists or returns 404 with Java? and Java check if file exists on remote server using its url But this con.getResponseCode() will always return status code "200". This mean my method will also download invalid image urls. So , I output my bufferStream as like... System.out.println(in.read(buf)); Invalid image URL produces "43". So , I add these lines of codes in my method. if (in.read(buf) == 43) { return null; } It is ok. But I don't think that will always satisfy. Has another way to get it ? am I right? I would really appreciate any suggestions. This problem may struct my head. Thanks for reading my question.

  • Javascript function to add X months to a date

    - by George
    Is there a built in equivalent to the .NET framework's DateAdd or AddMonths functions? I'm looking for the easiest, cleanest way to add X month to a Javascript date. I'd rather not handle the rolloing over of the year as done here. or have to write my own function as done here. Is there something built in that is as nice as the .NET Date.AddMonths function? Or something close?

  • Can I upload an object in memory to FTP using Python?

    - by fsckin
    Here's what I'm doing now: mysock = urllib.urlopen('http://localhost/image.jpg') fileToSave = mysock.read() oFile = open(r"C:\image.jpg",'wb') oFile.write(fileToSave) oFile.close f=file('image.jpg','rb') ftp.storbinary('STOR '+os.path.basename('image.jpg'),f) os.remove('image.jpg') Writing files to disk and then imediately deleting them seems like extra work on the system that should be avoided. Can I upload an object in memory to FTP using Python?

  • Width of Repeating Backgrounds

    - by tdskate
    Hello. What's best, a repeating background of 100px wide so that the actual file doesn't need to be redrawn 1000X times in width, or a 1px file that probably has smaller file size, but the browser will need to redraw it a lot more. Thanks.

  • Virtual Includes not recognized

    - by pfunc
    I am attempting to include a header in my html file. <!--#include virtual="/header.shtml" -- This is not being read by the browser. The file works fine when I go to it alone. It works fine when I had it in the header (not through an include file). Do some servers not allow this kind of include?

  • JSON.parse vs. eval()

    - by Kevin Major
    My Spider Sense warns me that using eval() to parse incoming JSON is a bad idea. I'm just wondering if JSON.parse() - which I assume is a part of JavaScript and not a browser-specific function - is more secure.
