  • MySQL, how to use returned data?

    - by aejo
    Well, I know there is a funciton mysql_fetch_array() and we can use it like this: while ($row = mysql_fetch_array($result)) { echo $row['name'] . "<br />"; } But is there any other way? For example, if there is only one element that can be returned, and not an array. Thanks)

  • Serializing data from a RSS feed in ASP.NET

    - by DotnetDude
    I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?

  • How can i optimize this python code

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • WMF image data validation?

    - by deostroll
    There is an image capturing device which gives its output in wmf. This output is stored in the database directly. We have cases where at times some of these images do not appear on a web page in IE. But if we right click on the page we are able to save the image on to the hard disk; meaning the image does exist on the page, but does not appear visible. I think this is because of some file corruption issue, but I don't know how to resolve it. We are however able to view such files using MS Picture Viewer (desktop app). Is there anyway we can detect such problematic files?

  • What's -mutableSetValueForKey: returning, actually? Is that something special?

    - by dontWatchMyProfile
    From the docs: You usually access to-many relationships using mutableSetValueForKey:, which returns a proxy object that both mutates the relationship and sends appropriate key-value observing notifications for you. So this returns an "intelligent" NSMutableSet which automatically lets the context delete objects when they get deleted from the set, and reverse? Is that a proxy object?

  • highlighting data values in a sql result set

    - by potatoe
    I can think of a number of ways to do this in PHP or even JavaScript, but I'm wondering if there's a SQL-based technique I'm overlooking. I have a database table, let's say 20 fields X 10 rows. I want to display the entire table on an web page, so I'd do something like SELCT * FROM data_table;, and then format the result set using HTML table tags. However, I'd also like to highlight values in the table based on whether they are the maximum or minimum value in their column. For example, I'd add bold tags around the max in each column. A resulting table might look something like this, with bold tags shown: id | field1 | field2 | field3 | ... 0 | 5 | 2 | <b>7</b> | ... 1 | 3 | <b>8</b> | 6 | ... 2 | <b>9</b> | 5 | 1 | ... ... I could do a separate SELECT with an ORDER BY for each field and then interpret the results, but that seems like a lot of extra DB access. My alternative right now is to just fetch the whole table, and then sort/search for the highlight values using PHP. Is there a better way?

  • Physical storage of data in Access 2007

    - by ste
    I've been trying to estimate the size of an Access table with a certain number of records. It has 4 Longs (4 bytes each), and a Currency (8 bytes). In theory: 1 Record = 24 bytes, 500,000 = ~11.5MB However, the accdb file (even after compacting) increases by almost 30MB (~61 bytes per record). A few extra bytes for padding wouldn't be so bad, but 2.5X seems a bit excessive - even for Microsoft bloat. What's with the discrepancy? The four longs are compound keys, would that matter?

  • Many Buttons on a Page, Need to send back Unique Post Data with each

    - by CoffeeAddict
    I'm listing out a bunch of cars with a button next to them that when clicked will need to perform a GET but also sends over that item's model.Name: @using (Html.BeginForm("GetCarUrl", "Car", FormMethod.Get, new { model = Model })) { if(Model.Cars != null && Model.Cars.Count > 0) { foreach (CarContent car in Model.Cars) { <p>@car.Name</p> } <input type="button" value="Get Car Url" class="submit" /> } So the page renders a bunch of hyperlinks and buttons: [hyperlink1] [submit] [hyperlink2] [submit] [hyperlink3] [submit] [hyperlink4] [submit] [hyperlink5] [submit] ... When a user clicks on any of the submits, I need to pass back its corresponding @car.CarType for that specific hyperlink Not sure how to go about this. My action method expects a @car.CarType for that specific car hyperlink to be sent to it

  • Passing data to notification page

    - by FRKT
    I'm not sure what the best way of populating a notification page is. I've been using sessions to populate it with information, but this falls short if the user is blocking cookies. I've considered passing it in HTTP GET variables, but I'm unsure whether it's a good alternative since its length is limited by some browsers. Which method do you prefer?
