  • effective retrieve for a voting system in PHP and MySQL

    - by Adnan
    Hello, I have a system where registered users can vote up/vote down comment for a picture. Something very similar to SO's voting system. I store the votes in a table with values as such; vote_id | vote_comment_id | vote_user_id | vote_date | vote_type Now I have few a question concerned the speed and efficiency for the following; PROB: Once a user opens the picture page with comments I need, if that user has already voted UP/DOWN a comment to show it like; "you voted up" or "you voted down" next to the comment (in SO it the vote image is highlighted) MY POSSIBLE SOL: Right now when I open a picture page for each comment I loop thru, I loop thru my table of votes as well and check if a user has voted and show the status (I compare the vote_user_id with the user's session). How efficient is this? Anyone have a better approach to tackle this kind of problem?

  • How to calculate a RTOS task's time

    - by Adnan
    Hello all, I have written a code in c for Arm7 using RTOS. There are multiple tasks who's priority is set to same level. So the tasks executes on round-robin base. There is an exception that one task (Default) has set to lower priority then the other task in rtos. So that if no task is running, the default or lower priority task runs. Now i want to calculate the exact total timing (time duration) for that default task runs. Can any one give some idea what to do .... and how to do in code.. Regards Dani

  • Image Masking Problem

    - by Adnan Sohail
    Hi I am doing image masking. First I was using C*GImageMaskCreate()* function for masking but now I am using your solution which you had posted for masking. My problem is it works fine on simulator but on device it is not transparent and it gives rectangle of mask image at background. The following is my code. Now tell me what I have to do? Thanks. CGContextRef mainViewContentContext; CGColorSpaceRef colorSpace; UIImage *orgImage=[UIImage imageNamed:@"orgimage.png"]; CGImageRef img = [orgImage CGImage]; colorSpace = CGColorSpaceCreateDeviceRGB(); mainViewContentContext = CGBitmapContextCreate (NULL, width, height, 8, 0, colorSpace, kCGImageAlphaPremultipliedLast); CGColorSpaceRelease(colorSpace); if (mainViewContentContext==NULL) return NULL; CGRect subImageRect; CGImageRef tileImage; subImageRect = CGRectMake(xCord,yCord,width,height); tileImage = CGImageCreateWithImageInRect(img,subImageRect); CGImageRef maskImage = mask_image.CGImage; CGContextClipToMask(mainViewContentContext, CGRectMake(0, 0, width, height), maskImage); CGContextDrawImage(mainViewContentContext, CGRectMake(0, 0, width, height), tileImage); CGImageRef mainViewContentBitmapContext = CGBitmapContextCreateImage(mainViewContentContext); CGContextRelease(mainViewContentContext); UIImage *theImage = [UIImage imageWithCGImage:mainViewContentBitmapContext]; CGImageRelease(mainViewContentBitmapContext);

  • _Painless_ integration of Eclipse with Vim?

    - by Adnan
    Hi, Has anyone managed to get Vim integrated into Eclipse painlessly? I just want to use Vim for the editor while retaining the general Eclipse interface. I have tried using Eclim plugin but the editor seemed to crash more often than work (the site said that the editor replacement functionality is still beta). On the flip side, is there any IDE which matches Eclipse's functionality -- mainly the integration with SVN, ant, etc. -- and is also able to use Vim? I mostly use eclipse for SAS SCL, Java and Javascript programming and find the eclipse editor too "mouse-y". I'd also like, in a perfect world, to use vimdiff as a diff viewer for SVN (we use TortoiseSVN) while checking for diffs or conflicts during merge etc. I admit I havent spent a lot of time trying to get these things to work. I feel guilty about spending too much time on potential wild-goose-chases while my other team members are working away at their code, perfectly content with all that eclipse has to offer. Edit: Just found this while desperately browsing around: Vim plugin.. Any experience using this? Its saturday afternoon in Kiwi land, so I'll try it later and update if no one has an opinion. From the claims on the site, it sounds perfect.

  • Creating a column of RadioButtons in Adobe Flex

    - by adnan
    I am having an un-predictable behavior of creating radio buttons in advancedDataGrid column using itemRenderer. Similar kind of problem has been reported at http://stackoverflow.com/questions/112036/creating-a-column-of-radiobuttons-in-adobe-flex. I tried to use the same procedure i.e. bind every radio button selectedValue and value attributes with the property specified in the property of the associated bean but still facing the problem. The button change values! The selected button becomes deselected, and unselected ones become selected. Here is the code of my advancedDataGrid: <mx:AdvancedDataGrid id="adDataGrid_rptdata" width="100%" height="100%" dragEnabled="false" sortableColumns="false" treeColumn="{action}" liveScrolling="false" displayItemsExpanded="true" > <mx:dataProvider> <mx:HierarchicalData source="{this.competenceCollection}" childrenField="competenceCriteria"/> </mx:dataProvider> <mx:columns> <mx:AdvancedDataGridColumn headerText="" id="action" dataField="criteriaName" /> <mx:AdvancedDataGridColumn headerText="Periode 1" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period1" value="{data}" selected="{data.period1}" group="{data.radioBtnGrpArray[0]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 2" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period2" value="{data}" selected="{data.period2}" group="{data.radioBtnGrpArray[1]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 3" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period3" value="{data}" selected="{data.period3}" group="{data.radioBtnGrpArray[2]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> </mx:columns> </mx:AdvancedDataGrid> Any work around is highly appreciated in this regard!

  • Select Table Rows by Grouping them Adjacent to each Other using XPath

    - by Adnan Yaseen
    I am not clear how to express my problem correctly in the question so forgive me if I am not able to properly convey my problem. I have following data. <tr class="header">Random Value 1</tr> <tr class="item">1</tr> <tr class="item">2</tr> <tr class="item">3</tr> <tr class="header">Random Value 2</tr> <tr class="item">4</tr> <tr class="item">5</tr> <tr class="item">6</tr> <tr class="header">Random Value 3</tr> <tr class="item">7</tr> <tr class="item">8</tr> <tr class="item">9</tr> What I want to acheive is that I want to select the with class header. I have achieved this by using the following line of code, HtmlNodeCollection headerNodes = doc.DocumentNode.SelectNodes("//tr[@class='header']"); Now I have all the header rows in the collection. Now I loop through all the header nodes and I want to get the table rows which are adjacent to the respective header rows. foreach (HtmlNode node in headerNodes) { HtmlNodeCollection itemNodes = ??? } My question is that what I should write here so that for header row with text "Random Value 1" I get the item rows 1,2 and 3. Similarly for header row with text "Random Value 2" I get the item row 4,5 and 6 and so on.

  • is this a secure approach in ActiveRecords in Rails?

    - by Adnan
    Hello, I am using the following for my customers to unsubscribe from my mailing list; def index @user = User.find_by_salt(params[:subscribe_code]) if @user.nil? flash[:notice] = "the link is not valid...." render :action => 'index' else Notification.delete_all(:user_id => @user.id) flash[:notice] = "you have been unsubscribed....." redirect_to :controller => 'home' end end my link looks like; http://site.com/unsubscribe/32hj5h2j33j3h333 so the above compares the random string to a field in my user table and accordingly deletes data from the notification table. My question; is this approach secure? is there a better/more efficient way for doing this? All suggestions are welcome.
