  • How can I keep data that a user has entered in my jQuery/Ajax pop-up form?

    - by Lucas McCoy
    I have a form on a website I'm working (you can see it here) on that allows my users to give feedback. It's an jQuery/Ajax popup form: $('.contact_us').click(function(){ var boxy_content; boxy_content += "<div style=\"width:300px; height:300px \"><form id=\"feedbacked\">"; boxy_content += "<p>Subject<br /><input type=\"text\" name=\"subject\" id=\"subject\" size=\"33\" /></p><p>Your E-Mail Address:<br /><input type=\"text\" name=\"your_email\" size=\"33\" /></p><p>Comment:<br /><textarea name=\"comment\" id=\"comment\" cols=\"33\" rows=\"5\"></textarea></p><br /><input type=\"submit\" name=\"submit\" value=\"Send >>\" />"; boxy_content += "</form></div>"; // Other code here... Is there anyway I can save what the user has entered (in case they see our error message when they try to submit)?

  • Python: Unpack arbitary length bits for database storage

    - by sberry2A
    I have a binary data format consisting of 18,000+ packed int64s, ints, shorts, bytes and chars. The data is packed to minimize it's size, so they don't always use byte sized chunks. For example, a number whose min and max value are 31, 32 respectively might be stored with a single bit where the actual value is bitvalue + min, so 0 is 31 and 1 is 32. I am looking for the most efficient way to unpack all of these for subsequent processing and database storage. Right now I am able to read any value by using either struct.unpack, or BitBuffer. I use struct.unpack for any data that starts on a bit where (bit-offset % 8 == 0 and data-length % 8 == 0) and I use BitBuffer for anything else. I know the offset and size of every packed piece of data, so what is going to be the fasted way to completely unpack them? Many thanks.

  • Excel 2007 - Worksheet is larger than the window

    - by Chris
    Hi This is an odd problem but frustrating none the less. I have a worksheet saved which is larger than the Excel 2007 "workarea". This means when I open the worksheet I cannot access the corners of the worksheet to reduce the size and the worksheets title bar area (with move,size,minimise etc) is hidden beneath the ribbon , even if I remove the ribbon , I still can't see the title bar. In Excel 2003 I've had a similar effect but I've always been able to hit the "alt" key to access the "Move" option. However in Excel 2007 , hitting "alt" brings up some shortcuts for the ribbon etc but I can't access the worksheet options. Has anyone else know how to access the worksheet drop down when this happens?

  • Border in DrawRectangle

    - by undsoft
    Well, I'm coding the OnPaint event for my own control and it is very nescessary for me to make it pixel-accurate. I've got a little problem with borders of rectangles. See picture: These two rectangles were drawn with the same location and size parameters, but using different size of the pen. See what happend? When border became larger it has eaten the free space before the rectangle (on the left). I wonder if there is some kind of property which makes border be drawn inside of the rectangle, so that the distance to rectangle will always be the same. Thanks.

  • Set height of Flex Accordion to height of tallest child

    - by Mike Deck
    By default the height of an Flex Accordion container is the height of the initially selected child. I'd like to be able to set the height to the tallest child so that no resizing or scrolling is necessary when other children are selected. I do not want to use the resizeToContent property. I want the size of the container to stay constant no matter what child is selected. My current thought is to extend the accordion class setting the creation policy to "all" and then override the measure function to loop through all the children and find the tallest one and use that for the height. This seems a little kludgy though, so I'd like to know if there is a better approach. Ultimately my question is: is there a way to set the size of an accordion container such that the container never resizes and scoll bars are never necessary to display any of the children?

  • iPhone - Make loadView entries fill up parent view?

    - by Eli
    I have a loadView call that basically places one view at the top (like a header) and one at the bottom (like a footer). It's possible via a passed in parameter to not have a header or a footer, to hide them later, or to resize the view. I have all this working, but it's very susceptible to breaking because the views can go in various places of various sizes and all must be manually set to the correct size or they will not use up all the space. I want one in between the two of them that automatically resizes to fill whatever space is not taken by the others. loadView doesn't seem to be able to obtain the size of its parent's frame (or where it's being fit in, exactly), nor do I see an obvious way to just put the center view at a certain position and have its width and height automatically adapted. Any ideas? If I'm not explaining myself well enough and you know Java Swing, think BorderLayout with a BorderLayout.NORTH, BorderLayout.SOUTH, and BorderLayout.CENTER component.

  • How to use UIWebView to get scrolling text ?

    - by srikanth rongali

I read that to use UIWebView for this. But, I could not understand how to use it. the text contains no url's no editing.(It need to be just static text to read). How can I do this ? Thank you.

  • Resize image on upload php

    - by blasteralfred
    Hi, I have a php script for image upload as below <?php $LibID = $_POST[name]; define ("MAX_SIZE","10000"); function getExtension($str) { $i = strrpos($str,"."); if (!$i) { return ""; } $l = strlen($str) - $i; $ext = substr($str,$i+1,$l); return $ext; } $errors=0; $image=$_FILES['image']['name']; if ($image) { $filename = stripslashes($_FILES['image']['name']); $extension = getExtension($filename); $extension = strtolower($extension); if (($extension != "jpg") && ($extension != "jpeg")) { echo '<h1>Unknown extension!</h1>'; $errors=1; exit(); } else { $size=filesize($_FILES['image']['tmp_name']); if ($size > MAX_SIZE*1024) { echo '<h1>You have exceeded the size limit!</h1>'; $errors=1; exit(); } $image_name=$LibID.'.'.$extension; $newname="uimages/".$image_name; $copied = copy($_FILES['image']['tmp_name'], $newname); if (!$copied) { echo '<h1>image upload unsuccessfull!</h1>'; $errors=1; exit(); }}} ?> which uploads the image file to a folder "uimages" in the root. I have made changes in the html file for the compact display of the image by defining "max-height" and "max-width". But i want to resize the image file on upload. The image file may have a maximum width of 100px and maximum height of 150px. The image proportions must be constrained. That is, the image may be smaller than the above dimensions, but, it should not exceed the limit. How can I make this possible?? Thanks in advance :) blasteralfred..

  • How to get details like PHP's stat() but using (raw) FTP (CURL)?

    - by Christian Sciberras
    Hello all! I'm new here. I've got a question related to PHP, FTP and CURL. I need to emulate PHP's stat() with CURL FTP. I already know that it may take more than one command to do it. Here's what I've got so far (PHP/STAT ... FTP/CURL): dev ino mode ... LIST * nlink uid ... LIST * gid ... LIST * rdev size ... SIZE (or better still, use from LIST) atime mtime ... MDTM ctime blksize blocks *How is FTP LIST used and parsed (preferably on a single file)? What I need most are the values for atime and ctime, there rest is to be filled for the sake of having full functionality. My end goal is to have a class for proper FTP access with streamWrapper functionality (so as to bypass allow_url_fopen). Cheers!

  • Bitmap Confusion Android

    - by Farhan
    I am getting an image from gallery in onActivityResult() through intent.getdata(). Now i get the data and set it to a bitmap, its size is 716x716 and its setting to full screen. (ImageView's width and height is set to wrap content). Now i created another bitmap after scaling the original through Bitmap.CreateScaledBitmap(orgBitmap,30,30,false); After this, i make sure these things(width,height n size) and they happen as they should be but the problem is that the image is still taking the full screen... rather it should only take 30dp x 30dp. Anyone have an idea what might be the problem??? Thanx

  • How to rotate an image properly in JPanel (Java)

    - by Bruce
    Hi guys, I'm working on rotating a loaded image. I set the graphics on a JPanel and then use standard AffineTransform in order to rotate it, say, 45 degrees. Unfortunately, the image is being cut, if it exceeds the panel area. How may I force JPanel to add scrolls to itself (while loading an image file, I would like to adjust the size of JPanel by adding the scrolls, without adjusting the size of JFrame). Or, in other words, how to correctly rotate the whole image? Thank you in advance for the reply!

  • Problem saving Text file in database using Hibernate

    - by Marquinio
    I'm having a problem saving large text files to MySQL database. If the text file size is around 5KB it successfully saves. If file is 148KB then I get this error from Hibernate: org.hibernate.exception.DataException: Could not execute JDBC batch update These is the SQL shows by Hibernate: Hibernate: insert into file_table (ID,FILE) values (?, ?) And in my hibernate file I'm using java.sql.Blob to store the file. Anyone knows why it fails to save a file size of 148KB but if I open that same file, cut it down to around 5KB, it will successfully save it? I thought the default limit was I think 2GB? This is weird. Thanks.

  • getResourceAsStream returns HttpInputStream not of the entire file

    - by khue
    Hi, I am having a web application with an applet which will copy a file packed witht the applet to the client machine. When I deploy it to webserver and use: InputStream in = getClass().getResourceAsStream("filename") ; The in.available() always return a size of 8192 bytes for every file I tried, which means the file is corrupted when it is copied to the client computer. The InputStream is of type HttpInputStream (sun.net.protocol.http.HttpUrlConnection$httpInputStream). But while I test applet in applet viewer, the files are copied fine, with the InputStream returned is of type BufferedInputStream, which has the file's byte sizes. I guess that when getResourceStream in file system the BufferedInputStream will be used and when at http protocol, HttpInputStream will be used. How will I copy the file completely, is there a size limited for HttpInputStream? Thanks a lot.

  • Referenced vector does not pass through functions

  • When using DrawText, what does TextFormatFlags.Internal (a.k.a. DT_INTERNAL) do?

    - by Daniel Stutzbach
    When using TextRenderer.DrawText(), what does setting the TextFormatFlags.Internal flag actually do? Equivalently, what does setting the DT_INTERNAL flag to Win32's DrawTextEx() function do? More to the point, when should I set that flag and when should I not set it? The documentation says: "Uses the system font to calculate text metrics", but I'm not entirely sure what that means. I've done some limited testing and setting the flag seems to change how the font is rendered when using a small font size, but doesn't seem to make a difference when using a large font size.

  • PHP, manipulating images and thumbnails?

    - by learner.php
    I am using php and mysql. I allow my registered users to upload photos, the photos are store in filesystem format, then I will keep the original/max size of : width: 1600px and heigh: 1200px. In the user profile page, I would like to display the image, it maybe one of the 5 types of thumnails: 500x500, 300x300, 200x200, 100x100 or 50x50. What is the best way to create the thumbnails, here are my current solutions: I am thinking of create 1 thumbnail, then from that thumbnail, i will resize in [img src="" width="XX"] tag, alternatively, store the different thumbnails size in database, then get and display it Create 5 thumbnails for each photos? (I am afraid this is a bad way) Whats the best practices?

  • Analyzing Python Code: Modulus Operator

    - by Bhubhu Hbuhdbus
    I was looking at some code in Python (I know nothing about Python) and I came across this portion: def do_req(body): global host, req data = "" s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host, 80)) s.sendall(req % (len(body), body)) tmpdata = s.recv(8192) while len(tmpdata) > 0: data += tmpdata tmpdata = s.recv(8192) s.close() return data This is then called later on with body of huge size, as in over 500,000 bytes. This is sent to an Apache server that has the max request size on the default 8190 bytes. My question is what is happening at the "s.sendall()" part? Obviously the entire body cannot be sent at once and I'm guessing it is reduced by way of the modulus operator. I don't know how it works in Python, though. Can anyone explain? Thanks.
