  • Layout question with BlackBerry IDE FieldManagers; how to emulate HTML's rowspan

    - by canadiancreed
    Hello all I'm trying to create a page where a list of items are displayed in a row where there are multiple columns on the left, but only one on the right, encased within a horizontialFieldManager. Currently I have the following code to attempt to do the following: VerticalFieldManager mainScreenManager = new VerticalFieldManager(); mainScreenManager.add(titleField); for (int i = 0; i < 10; i++) { HorizontalFieldManager itemAreaManager = new HorizontalFieldManager(); VerticalFieldManager itemTextFieldsAreaManager = new VerticalFieldManager(); itemTextFieldsAreaManager.add(new RichTextField(contentArticleTitle[i])); itemTextFieldsAreaManager.add(new RichTextField(contentArticleDate[i])); itemTextFieldsAreaManager.add(new SeparatorField()); itemAreaManager.add(itemTextFieldsAreaManager); itemAreaManager.add(new ButtonField("", 0)); mainScreenManager.add(itemAreaManager); }; add(mainScreenManager); Now the issue I'm experiencing is probably obvious to those familiar with managers; the horizontialFieldManager has the first item added to it consuming the entire width available, thereby never showing the button. What I'm wondering is how can I tell this in an extended class to only take up a certain percentage of the available width? I've tried subLayout and setting the width to be a certain amount, but it will just show the button instead of the text (pretty much same problem, just reversed)

  • Django Save Incomplete Progress on Form

    - by jimbob
    I have a django webapp with multiple users logging in and fill in a form. Some users may start filling in a form and lack some required data (e.g., a grant #) needed to validate the form (and before we can start working on it). I want them to be able to fill out the form and have an option to save the partial info (so another day they can log back in and complete it) or submit the full info undergoing validation. Currently I'm using ModelForm for all the forms I use, and the Model has constraints to ensure valid data (e.g., the grant # has to be unique). However, I want them to be able to save this intermediary data without undergoing any validation. The solution I've thought of seems rather inelegant and un-django-ey: create a "Save Partial Form" button that saves the POST dictionary converts it to a shelf file and create a "SavedPartialForm" model connecting the user to partial forms saved in the shelf. Does this seem sensible? Is there a better way to save the POST dict directly into the db? Or is an add-on module that does this partial-save of a form (which seems to be a fairly common activity with webforms)? My biggest concern with my method is I want to eventually be able to do this form-autosave automatically (say every 10 minutes) in some ajax/jquery method without actually pressing a button and sending the POST request (e.g., so the user isn't redirected off the page when autosave is triggered). I'm not that familiar with jquery and am wondering if it would be possible to do this.

  • Placing text on UIView in custom location

    - by JAM
    I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

  • remove 2 subviews in one go.

    - by Pavan
    hi, I am trying to remove two viewcontrollers (that have been added on top of each other) with one method. I have made the views in interfacebuilder. they all have their own .h and .m files to go with it. Scenario I am in: I have a main menu which has the view2 header file imported. In a method I add the second view on top of the superview like so view2ViewController * view2 = [[view2ViewController alloc] initWithNibName:@"view2ViewController" bundle:nil]; [self.view addSubview:view2.view]; then in view 2 I have added the view 3 header file so i can add view 3 as a subview ontop of view2. i have another method which is connected again to interface builder to a UIButton so upon button press a method gets called in view2 which adds view 3 on top in exactly the same way like so: view3ViewController * view3 = [[view3ViewController alloc] initWithNibName:@"view3ViewController" bundle:nil]; [self.view addSubview:view3.view]; What im trying to solve: I have a button in view 3 which should remove view 3.... and then it should also remove view 2 aswell so the main screen is visible. How can this be achieved? What I have so far: [self.view removeFromSuperview]; This however only removes View 3... but leaves view 2 in place. What needs to be modified so that i can remove view 2 as well?? Any help is appreciated.

  • Prevent Apache from answering invalid requests

    - by nickdnk
    I have an Apache web-server that acts as a web front-end for iPhone and iPad applications that communicate by POST and JSON only. Is there any way to prevent Apache from answering requests that are invalid? I can see my error log is filled with attempts to open files such as /admin.php /index.php etc - files that don't exist on my server. I believe this is possible with IIS, but can you do the same thing with Apache? Basically I want the request to appear timed out unless you post exactly the right content to the right file - or at least if you do not request an existing file. This would make the server appear non-existing to everyone but my iPhone users as all communication is SSL and directories are not really guess-able. I did disable the ServerTokens and all that, but I still get File not found etc. when I access the server requesting a random file, which is what these bots do constantly.

  • Empty R environment becomes large file when saved

    - by user1052019
    I'm getting behaviour I don't understand when saving environments. The code below demonstrates the problem. I would have expected the two files (far-too-big.RData, and right-size.RData) to be the same size, and also very small because the environments they contain are empty. In fact, far-too-big.R ends up the same size as bigfile.RData. I get the same results using 2.14.1 and 2.15.2, both on WinXP 5.1 SP3. Can anyone explain why this is happening? Thanks. a <- matrix(runif(1000000, 0, 1), ncol=1000) save(a, file="c:/temp/bigfile.RData") test <- function() { load("c:/temp/bigfile.RData") test <- new.env() save(test, file="c:/temp/far-too-big.RData") test1 <- new.env(parent=globalenv()) save(test1, file="c:/temp/right-size.RData") } test()

  • php: parsing and converting array structure

    - by mwb
    I need to convert one array structure into another array structure. I hope someone will find it worthy their time to show how this could be done in a simple manner. It's a little above my array manipulation skills. The structure we start out with looks like this: $cssoptions = array( array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'width' , 'value' => '200px' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'margin-right' , 'value' => '20px' ) // end data set , array( 'group' => 'Colors' , 'selector' => '#content' , 'rule' => 'color' , 'value' => '#444' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '.sidebar' , 'rule' => 'margin-top' , 'value' => '10px' ) // end data set ); // END $cssoptions It's a collection of discreet datasets, each consisting of an array that holds two key = value pairs describing a 'css-rule' and a 'css-rule-value'. Further, each dataset holds a key = value pair describing the 'css-selector-group' that the 'css-rule' should blong to, and a key = value pair describing a 'rule-group' that should be used for structuring the rendering of the final css into a neat css code block arranged by the kind of properties they describe (colors, measurement, typography etc..) Now, I need to parse that, and turn it into a new structure, where the: 'rule' => 'rule-name' , 'value' => 'value-string' for each dataset is converted into: 'rule-name' => 'value-string' ..and then placed into a new array structure where all 'rule-name' = 'value-string' pairs should be aggregated under the respective 'selector-values' Like this: '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block ..and finally all those blocks should be grouped under their respective 'style-groups', creating a final resulting array structure like this: $css => array( 'Measurements' => array( '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block , '.sidebar' => array( 'margin-top' => '10px' ) // end selector block ) // end rule group , 'Colors' => array( '#content' => array( 'color' => '#444' ) // end selector block ) // end rule group ); // end css

  • Chrome : type in textboxes instead of selecting them

    - by rlb.usa
    Hi guys, not sure what is happening but quite often i go to highlight/doubleclick text in a textbox in Google's Chrome browser, and somehow the textbox itself gets selected. I have to redo my selection so it selects the text inside... It is hard to explain but is it possible that whenever I have a textbox selected, when I type, the text I type goes in the box (instead of nowhere)? It seems like a rather uh, silly/stupid question, but it would save me time and make my browsing more efficient. I can work a mouse and type just as well as anyone else, Chrome is the only browser I have trouble in where it likes to select the textboxes instead of the text inside the textboxes. I love Chrome.

  • Manually manipulating ArrayList

    - by jsan
    I have an assignment where I have to create a deque, however I am not allowed to use any built-in classes or interfaces. I am implementing my deque using an array list. My problem is that when I have to, for instance, add to the beginning of the array list (beginning of the queue), i am not allowed to do this: public void addFirst(ArrayList<Integer> array) { array.add(0, int); } Is there a way to do this without using the add() function? Such as manually adding to the front and shifting the rest of the array to the right? Or maybe creating a new array list and copying...I'm not sure. Any help would be great; I have a bunch of functions to write, and getting the first one done will definitely put me in the right direction. Thanks

  • Div smart width

    - by Mark
    see fiddle html <div class="e" style="left:5px;top:5px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbbbbbbbb</div> <div class="e" style="left:5px;top:100px;">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>? css .e { font-size: 10px; font-family: arial; background-color: yellow; position: absolute; max-width: 300px; } you will notice the 2nd div fits the size of the content exactly, but on the first div there's a bunch of empty space to the right of the a's and b's. This is because the div hit its max width of 300px and then wrapped the b's to a 2nd line. The wrapping is good, but then I would expect the div to then shrink back down to the width of the a's so that there's no empty space to the right. Is it possible to get it to do this? Tested in Chrome and FF.

  • How do I add items to the Finder context menu in Mac OS X?

    - by mystro
    I'm in the process of porting a Windows application to OS X (we wrote it in Java so most of the code is portable), but what I'm currently unsure of is how to add context menu items in the Finder window when the user right clicks on an item (i.e. I wish to add some items to the the menu that has "Open" "Open with" , "Get Info", etc... when the user right clicks). Most of the articles I've found deal specifically with Windows (I've searched for "context menus" and "shell extension", but I believe I may be searching the wrong terms), so I'm curious as to how to go about adding this in Mac or what literature I should be reading.

  • Selecting the correct input field using jquery

    - by rshivers
    I'm trying to select the id's of dynamic input fields in my code. When clicking a button, the form will create a form field like this: <td><input type="text" id="field_a_1"></td> <td><input type="text" id="field_b_1"></td> <td><input type="text" id="field_c_1"></td> When I click on the button again I get this: <td><input type="text" id="field_a_2"></td> <td><input type="text" id="field_b_2"></td> <td><input type="text" id="field_c_2"></td> What I want to do is select only the field id that I need to pull the value from that particular input and pass it to a variable like this: var example = $(":input:eq(0)").val(); I know that by adding the :eq(0) after the :input selector it will only grab the id for field_a_1, so how do I set it up so that I can pull just the field that I need to assign it to a variable?

  • 2 identical PCs - can I swap a single hard drive between and expect Windows 7 to work? [closed]

    - by rgvcorley
    I currently work in 2 different locations, traveling between the 2 every few weeks or so. I currently have screens, kb, mouse etc... in both locations, so I just pick up my tower case when I want to move to the other location. However to make moving easier I was thinking of buying 2 tower cases with hot swappable drive bays on the front and installing identical hardware in each one. This would allow me to pull the drives out and just take them with me and plug them into the PC at the other location. Would windows 7 complain? I'm not fussed about buying licenses for both PCs, but would I have any problems with drivers due to the different serial numbers of the components?

  • changes in main.xml are not reflected in the android app in netbeans

    - by nitish712
    I am new to android apps. I am using the netbeans 7.0.1 IDE to develop android apps. I have written the following code in the main java file: package com.test.helloworld; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class helloworld extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView t1=new TextView(this); t1.setText("hello world..!!!!"); setContentView(t1); } } This was working fine. I edited the main.xml file to display a textfield and button as follows: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send"/> <EditText android:id="@+id/edit_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:hint="@string/edit_message"/> </LinearLayout> Of course I have added all the corresponding strings in strings.xml. But when I try to run my app these weren't displaying... :( . I mean the same string that was displayed previously was being displayed. Can anybody figure out what is the mistake? thanx...

  • Windows 7 Laptop, cursor jumping after typing the letters "y" or "t" [closed]

    - by Dave K
    My wife has an HP laptop running windows 7. She has a very frustrating problem when typing: in some, but not all cases, typing the letter's "y" or "t" will cause the cursor to jump back a few lines or some number of words. The result is that she ends up typing over whatever it was that she was working on. (as a matter of fact, I just experienced this while typing this question on her computer with the phrase: "typing the letter..." above.) I've installed the latest drivers for her touchpad from Synaptic and disabled tap touching and gesture features to rule out simple unintended mouse clicks. Still the "y" and "t" keys continue to cause problems.

  • HTML form with single text field + preventing postback in Internet Explorer

    - by SudheerKovalam
    I have noticed a rather strange behaviour in IE. I have a HTML form with a single input text field and a submit button On Submit click I need to execute a client side JavaScript function that does the necessary. Now when I want to prevent the postback in the text field (on enter key press) I have added a key press JavaScript function that looks like this: <input type=text onkeypress="return OnEnterKeyPress(event)" /> function OnEnterKeyPress(event) { var keyNum = 0; if (window.event) // IE { keyNum = event.keyCode; } else if (event.which) // Netscape/Firefox/Opera { keyNum = event.which; } else return true; if (keyNum == 13) // Enter Key pressed, then start search, else do nothing. { OnButtonClick(); return false; } else return true; } Strangly this doesn't work. But if I pass the text field to the function : <input type=text onkeypress="return OnEnterKeyPress(this,event);" /> function OnEnterKeyPress(thisForm,event) { var keyNum = 0; if (window.event) // IE { keyNum = event.keyCode; } else if (event.which) // Netscape/Firefox/Opera { keyNum = event.which; } else return true; if (keyNum == 13) // Enter Key pressed, then start search, else do nothing. { OnButtonClick(); return false; } else return true; } I am able to prevent the postback. Can anyone confirm what is exactly happening here?? the HTML form has just one text box and a submit button The resultant o/p of the JavaScript function executed on submit is displayed in a HTML text area in a separate div.

  • CURL request incomplete, suspect timeout but not sure.

    - by girlygeek
    I am currently using CURL via a php script running as daily cron to export product data in csv format from a site's admin area. The normal way of exporting data will be to go to the Export page in a browser, and set the configuration, then click on "export data" button. But as the number of products I am exporting is very large, and it takes more than 5-10 mins to export the data, I've decided to use php's curl function to mimic this on a daily basis via cron. Previously, it is working fine, but recently as I increased the number of products in the store by 500+, the script fails to return the exported data. Testing it manually via clicking on the "export" button in a browser, does return the data correctly. Thus there is no "timeout" issue with running the export in a browser manually. I've tested and by removing/decreasing the number of products (thus the time needed), the php-curl script works fine again when run from cron. So I suspect that it has something to do with timeouts issue, specifically with the curl function in php. I've set both CURLOPT_TIMEOUT and CURLOPT_CONNECTTIMEOUT to '0' respectively to try. In the php-curl script, I've also set "set_time_limit(3000)". But still it does not work, and the request will timeout, with the script failing to return with a complete set of csv data. Any help in helping me resolve/understand this issue will be much appreciated!

  • Prevent empty form input array from being posted?

    - by user355295
    Sorry if this has been answered somewhere; I'm not quite sure how to phrase the problem to even look for help. Anyway, I have a form with three text input boxes, where the user will input three song titles. I have simple PHP set up to treat those input boxes as an array (because I may want, say, 100 song titles in the future) and write the song titles to another document. <form method="post"> <input type="text" name="songs[]" value="" /> <input type="text" name="songs[]" value="" /> <input type="text" name="songs[]" value="" /> <button type="submit" name="submit" value="submit">Submit</button> </form> <?php if (isset($_POST['submit'])) { $open = fopen("test.html", "w"); if(empty($_POST['songs'])) { } else { $songs = $_POST['songs']; foreach($songs as $song) { fwrite($open, $song."<br />"); }; }; }; ?> This correctly writes the song titles to an external file. However, even when the input boxes are empty, the external file will still be written to (just with the <br />'s). I'd assumed that the if statement would ensure nothing would happen if the boxes were blank, but that's obviously not the case. I guess the array's not really empty like I thought it was, but I'm not really sure what implications that comes with. Any idea what I'm doing wrong? (And again, I am clueless when it comes to PHP, so forgive me if this has been answered a million times before, if I described it horribly, etc.)
