• Display one div if nothing is selected

  - by Levani

  I use this javascript to display different div classes upon selection. I need to display one div class if nothing is selected, for example when page is loaded, and that replace it with one of the divs according to the selection... <script type="text/javascript"><!-- var lastDiv = ""; function showDiv(divName) { // hide last div if (lastDiv) { document.getElementById(lastDiv).className = "hiddenDiv"; } //if value of the box is not nothing and an object with that name exists, then change the class if (divName && document.getElementById(divName)) { document.getElementById(divName).className = "visibleDiv"; lastDiv = divName; } } //--> </script> css: <style type="text/css" media="screen"><!-- .hiddenDiv { display: none; } .visibleDiv { display: block; border: 1px grey solid; } --></style> HTML: <form id="FormName" action="blah.php" method="get" name="FormName"> <select name="selectName" size="1" onChange="showDiv(this.value);"> <option value="">Choose One...</option> <option value="one">first</option> <option value="two">second</option> <option value="three">third</option> </select> </form> <p id="one" class="hiddenDiv">This is paragraph 1.</p> <p id="two" class="hiddenDiv">This is paragraph 2.</p> <p id="three" class="hiddenDiv">This is paragraph 3.</p> Can anyone please help?

• How to set a EditText in a certain column of a TableLayout?

  - by Nick

  I have a TableLayout on one Android Activity UI. It has two columns. Now I need to add a new row, and put an EditText box in second column of that new row. And also, I want that EditText full fill the whole cell. I have some code like this: TableRow tr = new TableRow(context); EditText et = new EditText(context); et.SetMaxLines(4); etText.setLayoutParams(new TableRow.LayoutParams(1)); //set it to the second coloumn tr.addView(et); tl.addView(tr); //tl is the tableLayout It puts the EditText in the second column fine, but the EditText is too small. I tried to use etText.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); but that seems to disabled the TableRow.LayoutParams setting. I guess each control can only have one LayoutParamas setting. So, how to make the EditText as a 4 lines text editor and also make sure it is in the second column of that row? Thanks.

• using respond_to format.js to replace the content of a textarea on rails

  - by Stacia

  I have some saved text in my create controller. If it's not stressful, I'd like it to populate a textarea on the page with the saved text along with displaying the error message fields (which is what's already happening). I've used things like replace_html before, but I don't know if there's an easy way to get to textarea or text field IDs and just replace the value of the text. For now I'm just going to do some javascript but it would be nice to know the rails shortcut. edit: I wasn't in the right mindset because this app uses extjs and was trying to figure out how to do it this way. The text box is actually an ext status bar (same as here : http://www.extjs.com/deploy/dev/examples/statusbar/statusbar-demo.html ) which doesn't get created until the page is finished loading. When I try to enter commnands like the first poster suggested, I get "setvalue is not a function". Playing with firebug on the page I can get it to set the value after loading by using (whatever method to get it through ext or scriptaculous).value = "lol" but none of the page update things work with this.

• How do you Bind to a ComboBox in a DataTemplate?

  - by discwiz

  I have a listbox that is bound to an observable collection of Audio (custom class). The Audio class has two properties, DisplayText (string) and a property called TarpIds (Observable Collection of Integer). I need to allow the user to change the TarpID in the combo box for each list item displayed and catch the selection change. I created a DataTemplate that styles the DisplayText property from the Audio object and adds a ComboBox to display the available TarpIDs for this audio (These are dynamic and unique to each Audio). The DisplayText works great, but I can not get the TarpIDs to display in the ComboBox. Here is what I have so far and thanks for any help. FYI I set the ItemSource at run time that binds the ListUploadAudio to the Observable Collection of Audio. <Border BorderBrush="Red" Background="WhiteSmoke" CornerRadius="8"> <Border.Resources> <DataTemplate x:Key="UploadLayout" DataType="Audio"> <StackPanel Orientation="Vertical"> <TextBlock Text="{Binding Path=DisplayText}" FontWeight="Bold" Foreground="Blue"> </TextBlock> <ComboBox x:Name="ListBoxTarpIDs" ItemsSource="{Binding Path=TarpIds}"> </ComboBox> </StackPanel> </DataTemplate> </Border.Resources> <ListBox x:Name="ListUploadAudio" BorderBrush="Transparent" Background="Transparent" Width="230" Margin="10" Height="200" IsSynchronizedWithCurrentItem="True" SelectionMode="Multiple" ItemTemplate="{DynamicResource UploadLayout}"> </ListBox> </Border>

• Setting up SVN (subvsersion) to manage our companies files, how to exclude large files from being ve

  - by Roeland

  Me and two other guys recently started our own web development company. We each work from our homes and have decided we want to keep one central location for all of our files. These files include word documents, spreadsheets, client files, designs.. etc. Anything pertaining to our company. I have a pretty solid internet connection and a windows 2008 server box sitting at home so I set up a subversion repository. Our file repository will look something like this. Clients Company A Design (photoshop files, wireframes, concepts) Documents ( logins, quotes, proposals etc) Site Backups Company B Design Documents Site Backups Prospects Company C Company D Our Company Our Website Documents (contract, operating procudres) My question is in regards to design files. The photoshop files that my designer works with range in sizes from 10mb to 100mb. I don't think we need to keep these files version-ed as this would eat up space incredibly fast. How do I go about controlling which files get version-ed, and which files are just stored. What I am thinking is that all documents need to be version-ed, and any files other then that should not be. Any help would be appreciated, thanks! Edit I am also curious whether this is the way to go. I just like this system since it keeps version of all my documents and at the same time. Also essentially I will have 3 backups in 3 different locations (3 local copies) so no need for backing it up. I am unsure of how svn would perform as purely a huge file repository.

• Rails partial gets double escaped when using link_to_function

  - by dombesz

  Hi, I have the following code. def add_resume_link(name, form) link_to_function name do |page| html = form.fields_for :resumes, @general_resume.resumes.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial => 'resume_form', :locals=>{:form=>form_parent} end page << "$('resumes').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, id) });" end end And on the resume_form i have somewhere: =add_skill_link("Add Skill", form, "resume_#{id}_skills") and the function looks like: def add_skill_link(name, form, id) link_to_function name do |page| html = form.fields_for :skill_items, @general_resume.skill_items.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial=>'skill_form', :locals=>{:form=>form_parent, :parent=>id} end page << "$('#{id}').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, new Date().getTime()) });" end end So basically i have a javascript code which dinamically adds a piece of html (add_resume) and contains another javascript code which dinamically adds a select box to the page. My problem is that the add_skill_link works fine if i use from the server side, i mean rendering from server side. And gets double escaped when using within the upper described way. I tried to remove the escape_javascript from the add_skill_link bit still not good. Any ideas?

• user interface pattern for associating single or many objects to an entity

  - by Samuel

  Need suggestions on implementing associating single or many objects to an entity. All soccer team players are registered individually (e.g. they are part of 'players' table) A soccer team has many players. The click sequence is like this:- a] Soccer team owner provides a name and brief description of the soccer team. b] Now it wants to add players to this team. c] You have the following button 'Add players to team' which lets you navigate to the 'View Players' page and lets you multi select users from there. Assuming this is a paginated list of players, how do you handle the following:- Do you provide a check box against each player and let the manager do a multi selection. If you need to add more players, it doesn't make sense to show the players who have been already added to the team. Do you mark those entries as not selectable or you would adding showing these entries. If you need to filter, do you provide search filters at the top of this page. Am looking for ideas on how to implement this or sites which have already done something similar.

• Specific Shopping Cart Recommendations

  - by Dean J

  I'm trying to suggest a solution for a friend who owns an existing web shop. The current solution isn't cutting it. The new solution needs to have a few things that look like they're enterprise-only if I go with Magento, and $12k a year for a store with maybe $20k in stock just doesn't work. The site should have items, which have one or more categories. Each category may have a parent category. Items have MSRP, and a discount rate by supplier, brand, and sometimes additional discount by product. When a user buys something, it should automatically setup a shipping label with UPS or USPS, depending on user's choice, and build two invoices; one to go in the box, one to go into records. This is crucial; it's low profit per item, so it needs to minimize labor here. Need to be able to have sales (limited by time), discount codes/coupon codes. Ideally would have private sales and/or members-only rates as well. It needs a payment gateway; Paypal/GCheckout-only isn't going to fly. Must be able to accept Visa/MC. Suggestions? I'm debating just building this myself in Java or PHP, but wanted to point my friend to a reasonable-cost solution that already exists if I can. This all seems pretty straightforward to code, save working with the UPS/USPS/Visa/MC APIs, and doing CSS for it.

• Why does my floating div push around other divs?

  I have a div which has a table which has a google map. I want to place a info box within the google map external to the map, just floating on top But I can't seem to get it right, the info div just pushes around the google map despite being on top of the map...

• How to provide a temporary URL for custom domain in Wordpress multisite install?

  - by Milan Babuškov

  I have a website with Wordpress 3.0.4 installation, set up as multisite install. Some users register their blogs as something.mydomain.com and that works automatically. However, some users prefer to use their own domain names like something.com. This also works fine once they set up the CNAME record to point to my server. However, it takes 24-48 hours for that change to take effect. I'd like to be able to offer the user a temporary URL that would work out-of-the-box until the DNS changes are propagated, but I have not idea how to do it? For example: something.com should also be accessible as: something.tempdomain.com I have control over "tempdomain" DNS setup. I thought about replacing $_SERVER variables in index.php or .htaccess file when temporary domain is accessed, and this works for the first page load. However, all the links in generated page point to original domain which is not yet ready. UPDATE: I managed to get it working for the site itself by manipulating $_SERVER variables so Wordpress thinks it's creating a page for different site. I did this in index.php, so before any WP code is run I'm using ob_start and ob_get_contents later to get the page generated by Wordpress and then str_replace the links back to temporary domain. The problem I still have is the admin page. Even though the link says: http://site1.tempdomain.com/wp-admin when opened in browser it redirects to maindomain.com/wp-signup.php?new=site1.tempdomain I don't understand how WP detects that I supplied "fake" domain when $_SERVER vars are changed?

• What are the best software/website UI design you have even seen?

  - by Edwin

  What are the best UI design in terms of usability and esthetics you have even seen? I mean both desktop software (of all OS) and website. My list: Picasa 3 - the way it organizes photos. Find-and-highlight-as-you-type in google Chrome. Dynamic search hints when entering something in the search box in Gmail. I'm not a Mac OS X user, but I have seen in most windows on the top toolbar there are both the icons and texts shown for each function, as apposed to on Windows I have seen many programs (MS Office included) have many small toolbar icons which you can hardly understand what they do until you hover the mouse on it for a while to see the hints (if any). The ability to search an setting in Eclipse IDE. the way to make 3D models in Google Sketchup. the way to label an email in Gmail. What are you list? Well, I couldn't resist to list some annoying UI design I have experienced and remember at this moment. IE on Windows server, when you visit the new website, you have to click many times to get it added to the white list before you can start browsing, IIRC, it's not fixed in IE 8 when that last time I used it on Windows 2008. The default search behavior in the File Explorer on Windows xp, that animated thing... the dialog that shows up when you are trying to save a plain text CSV file in Excel after applied some formatting options which does not compatible with CSV.

• GetIpAddrTable() leaks memory. How to resolve that?

  - by Stabledog

  On my Windows 7 box, this simple program causes the memory use of the application to creep up continuously, with no upper bound. I've stripped out everything non-essential, and it seems clear that the culprit is the Microsoft Iphlpapi function "GetIpAddrTable()". On each call, it leaks some memory. In a loop (e.g. checking for changes to the network interface list), it is unsustainable. There seems to be no async notification API which could do this job, so now I'm faced with possibly having to isolate this logic into a separate process and recycle the process periodically -- an ugly solution. Any ideas? // IphlpLeak.cpp - demonstrates that GetIpAddrTable leaks memory internally: run this and watch // the memory use of the app climb up continuously with no upper bound. #include <stdio.h> #include <windows.h> #include <assert.h> #include <Iphlpapi.h> #pragma comment(lib,"Iphlpapi.lib") void testLeak() { static unsigned char buf[16384]; DWORD dwSize(sizeof(buf)); if (GetIpAddrTable((PMIB_IPADDRTABLE)buf, &dwSize, false) == ERROR_INSUFFICIENT_BUFFER) { assert(0); // we never hit this branch. return; } } int main(int argc, char* argv[]) { for ( int i = 0; true; i++ ) { testLeak(); printf("i=%d\n",i); Sleep(1000); } return 0; }

• Alternative to position: relative; for overflow: auto; bug in IE7.

  - by Myles

  I have content arranged thusly: <div id="thumbnails" style="width: 40px; overflow: auto;"> <div style="float:left; width: 20px;">content</div> <div style="float:left; width: 20px;">content</div> <div style="float:left; width: 20px;">content</div> <div style="float:left; width: 20px;">content</div> <div style="float:left; width: 20px;">content</div> <div style="float:left; width: 20px;">content</div> In IE7 this shows up with the content running out of the scrollable box. The answer everywhere is to make #thumbnails position:relative. My problem is that the items in #thumbnails are scriptaculous draggables that drag outside of thumbnails with a ghost of the element that is positioned absolutely. This does not go over well if the parent is positioned:relatively because now the absolute positions are relative to #thumbnails and not the <body>. Does anyone know an alternative solution to the IE7 bug?

• Problem prompting user for extended permissions using showPermissionDialog in FB page tab

  - by snipe

  I have an FBML app that will use the tab as a promo tab before the full app goes live. The purpose of the promo tab is to allow users to opt in to email notifications (using the FB API sendNotifications call), so I need to prompt them to allow the app and grant extended permissions on that promo tab. The tab code is: <?php require_once 'config.php'; ?> <form id="form1"> <h1> <a href="#" clickrewriteform="form1" clickrewriteurl="http://www.mydomain.com/fanpageajax/result.php" clickrewriteid="allowapp">Step 1. Allow the Application</a> </h1> <div id="allowapp"></div> </form> <h1><a onclick="Facebook.showPermissionDialog('email');return false;"> Step 2. Grant extended permissions (intab)</a></h1> The result.php page just tags the API to ensure the allow prompt will show up. The problem is with the Step 2. Once the user has allowed the app, and they click on the Step 2, nothing happens. If they click on it twice, THEN the extended permissions dialog box popups up, but it asks them to grant extended permissions TWICE. OR.... If the user clicks on Step 1, and allows the app, and then reloads the fan page tab, they only have to click on the Step 2 link once, and the permissions show up. Anyone have any ideas? I have been beating myself in the head over this for hours.

• Why does this javascript code have an infinite loop?

  - by asdas

  optionElements is a 2d array. Each element has an array of length 2. These are an integer number and an element. I have a select list called linkbox, and i want to add all of the elements to the select list. The order I want them to go in is important, and is determined by the number each element has. It should be smallest to highest. So think of it like this: optionElements is: [ [5, <option>], [3, <option], [4, <option], [1, <option], [2, <option]] and it would add them to link box in order of those numbers. BUT that is not what happens. It is an infinite loop after the first time. I added the x constraint just to stop it from freezing my browser but you can ignore it. var b; var smallest; var samllestIndex; var x = 0; while(optionElements.length > 0 && ++x < 100) { smallestIndex = 0; smallest = optionElements[0][0]; b = 0; while( ++b < optionElements.length) { if(optionElements[b][0] > smallest) { smallestIndex = b; smallest = optionElements[b][0]; } } linkbox.appendChild(optionElements[smallestIndex][1]); optionElements.unshift(optionElements[smallestIndex]); } can someone point out to me where my problem is?

• Creating Modules for VB Program (Similar to firefox add on)

  - by Assimilater

  Hi all. I have a contact manager program that I'd like to design for multiple network marketing companies. My desired structure would include a core program which covers basic contact management functions. After that one could purchase a module for their specific network marketing company. This module would contain a variety of controls that the original program would need to be able to manipulate. Here is an example of what it would have to have: A group box containing buttons that link to a genealogy view, and the option to import one's donwnline from the back office provided by a company. A panel which is displayed on the contact page allowing the user to input business information or which will be filled by importing a downline from the back office: ie business ID, qualification level, sponsor information etc. a panel displayed when one searches for contacts on the contact list page which allows the user to sort based on information such as when they joined, what their business id is and so forth. a panel which is displayed in a personal business overview page which presents to an individual how many people in their downline are at each qualification level and develop a mailing list for individuals of a certain qualification level. I have the code developed to perform all these functions, I just wanted to give you an example of what needed to be done. I'm thinking that what I'm trying to create is a library that one can download and the program will recognize, but I'm not really sure where to go. What I'm really trying to do is figure out what kind of file I can make that will contain all this code and the GUI information that the program will recognize. Any ideas? With thanks, John

• PHP resizing PNGs results in corrupted files

• Stretch ListBox Items hit area to full width if the ListBox?

  - by Nicholas

  I've looked around for an answer on this, but the potential duplicates are more concerned with presentation than interaction. I have a basic list box, and each item's content is a simple string. The ListBox itself is stretched to fill it's grid container, but each ListBoxItem's hitarea does not mirror the ListBox width. It looks as if the hitarea (pointer contact area) for each item is only the width of the text content. How do I make this stretch all the way across, regardless of the text size. I've set HorizontalContentAlignment to Stretch, but this doesn't solve my problem. My only other guess is that the content is actually stretching, but the background is invisible and so not capturing the mouse pointer. <ListBox Grid.Row="1" x:Name="ProjectsListBox" DisplayMemberPath="Name" ItemsSource="{Binding Path=Projects}" SelectedItem="{Binding Path=SelectedProject}" HorizontalContentAlignment="Stretch"/> The XAML is pretty straight forward on this. If I mouse over the text in one of the items, then the entire width of the item becomes active. I guess I just need to know how to create an interactive background that is invisible.

  Scanner scanner = new Scanner(lapsPerMile_st); if (!scanner.hasNextDouble()) { Context context = getApplicationContext(); String msg = "Please Enter Digits and Decmials Only"; int duration = Toast.LENGTH_LONG; Toast.makeText(context, msg, duration).show(); lapsPerMileEditText.setText(""); return; } else { //Edit box has only digits, Set data and display stats data.setLapsPerMile(Integer.parseInt(lapsPerMile_st)); lapsRunLabel.setVisibility(0); lapsRunTextView.setText(Integer.toString(data.getLapsRun())); milesRunLabel.setVisibility(0); milesRunTextView.setText(Double.toString(data.getLapsRun()/data.getLapsPerMile())); } <EditText android:id="@+id/mileCount" android:layout_width="100dp" android:layout_height="wrap_content" android:layout_marginTop="110dp" android:inputType="numberDecimal" android:maxLength="4" /> For some reason if I enter a non decimal number such as 3, or 5, it works fine but when I enter a floating point such as 3.4 or 5.8 it force closes. I cant seem to figure out whats going on. Any ideas? Thanks

• Catching exception in Main() method

  - by Corvin

  Consider the following simple application: a windows form created by a "new C# windows application" sequence in VS that was modified in a following way: public static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); try { Application.Run(new Form1()); } catch (Exception ex) { MessageBox.Show("An unexpected exception was caught."); } } Form1.cs contains the following modifications: private void Form1_Load(object sender, EventArgs e) { throw new Exception("Error"); } If I press F5 in IDE, then, as I expect, I see a message box saying that exception was caught and the application quits. If I go to Debug(or Release)/bin and launch the executable, I see the standard "Unhandled exception" window, meaning that my exception handler doesn't work. Obviously, that has something to do with exception being thrown from a different thread that Application.Run is called from. But the question remains - why the behavior differs depending on whether the application has been run from IDE or from command line? What is the best practice to ensure that no exceptions remain unhandled in the application?
