  • if string is alphabetically greater than other string in objective

    - by Jonathan
    I'm trying to use an if statement to work out which of 2 strings comes first alphabetically. Like with numbers and greater and less than: if (1 < 2) { just with strings: if(@"ahello" < @"bhello") { Or would I have to have a string containing all the letters and then check the index of the first char in each string and see which index is greater, and the index that is less than the other comes first in the alphabet and then if they are equal move on to the next char and repeat?

  • [LaTeX] positions of page numbers, position of chapter headings, chapters AND Table of Contents, Ref

    - by kaikanmonaco
    I am writing my PhD thesis (120+ pages) in latex, the deadline is approaching and I am struggling with layout problems. I am using the documentstyle book. I am posting both problems in this one thread because I am not sure if the solution might be related to both problems or not. Problems are: 1.) The page numbers are mostly located on the top-right of each page (this is correct and where I want them to be). However, only on the first page of chapters and on the first page of what I call "special chapters", the page number is located bottom-centered. With "special chapters" I mean: List of Contents, List of Figures, List of Tables, References, Index. My university will not accept the thesis like this. The page number must ALWAYS be top-right one each page, even if the page is the first page of a chapter or the first page of something like the List of Contents. How can I fix this? 2.) On the first page of chapters and "special chapters" (List of Contents...), the chapter title is located far too low on the page. This is the standard layout of LaTeX with documentstyle book I think. However, the chapter title must start at the very top of the page! I.e. the same height as the normal text on the pages that follow. I mean the chapter title, not the header. I.e., if there is a chapter called "Chapter 1 Dynamics of foobar under mechanical stress" then that text has to start from the top the page, but right now it starts several centimeters below the top. How can I fix this? Have tried all kinds of things to no effect, I'd be very thankful for a solution! Thanks.

  • how to make a simple collision detection of bitmaps in Android

    - by Dritan Berna
    I already have a code with collision but it has check for winners and ontouch method that I don't really need because my bitmaps are moving itself and I just want them to collide if they overlap. private boolean checkCollision(Grafika first, Grafika second) { boolean retValue = false; int width = first.getBitmap().getWidth(); int height = first.getBitmap().getHeight(); int x1start = first.getCoordinates().getX(); int x1end = x1start + width; int y1start = first.getCoordinates().getY(); int y1end = y1start + height; int x2start = second.getCoordinates().getX(); int x2end = x2start + width; int y2start = second.getCoordinates().getY(); int y2end = y2start + height; if ((x2start >= x1start && x2start <= x1end) || (x2end >= x1start && x2end <= x1end)) { if ((y2start >= y1start && y2start <= y1end) || (y2end >= y1start && y2end <= y1end)) { retValue = true; } } return retValue; }

    Hi All, I have a RadioGroup and two RadioButtonField added in a VerticalFieldManager. I want put an EditField for the first RadioButtonField horizontally. For ex: I have two RadioButtonField as "Enter number here:" otherwise user can choose "Number from existing Database:" in the second RadioButtonsField. In the first field "Enter number here:" i need provide an EditField horizontally next to first RadioButtonField, for him to type. I am trying to put an EditField horizoally but it doesn't show EditField horizonatally to the first RadioButtonField. May i know how to do that (or) any samples to do that? Thanks.

  • Java return to position N in call stack.

    - by Finbarr
    Using the return keyword in Java code will return execution to the last piece of calling code in the call stack. If object foo calls baz.bar(), the return keyword in the bar method will continue code execution in foo. Let's say I have object foo that calls foofoo that calls foofoofoo in the above scenario, and foofoofoo calls baz.bar(). Is there anyway in Java to use the return keyword, or something else, so that the code in the bar method can return all the way back up to foo? (WITHOUT THROWING AN EXCEPTION)

  • How do I prevent JAXB from generating Java from imported schema?

    - by Mark
    I've got two Java projects, both generate Java classes based on a schema definition, I'm using xjc to create the classes. My second project depends on a class from the first project, and in particular, one of the classes I'd like to generate in my second project needs to use one of the types from the first project. To accomplish this dependency at the schema level, I'm using a simple xsd:import to map the namespace to a particular schema. JAXB works just fine with this condition, except it also generates the first project's types in the second project. So after running have something like this: Project A +-- com.foo.bar +-- TypeA Project B +-- com.foo.asdf +-- TypeB +-- com.foo.bar +-- TypeA The second "TypeA" is undesirable, and I'd like to never generate it in the first place. How do I instruct JAXB not to generate the classes for "TypeA" that it finds as a result of the import statement?

  • JQuery Validation - Wrap offending field in a div.

    - by Samuurai
    Hi, It's my first time using StackOverFlow and first time trying to set up jQuery Validation. It's displaying <label> tags with the error messages as default behaviour, however the way my CSS is set up I need a div to wrap around the offending element and a message display in <p> tags. Without errors, my html looks like this: <div class="grid-26 append-2"> <p class="noMarginBottom"> <label>First Name</label> <div class="jNiceInputWrapper"> <div class="jNiceInputInner"> <input type="text" class="text jNiceInput" name="name"/> </div> </div> </p> <span class="clear"/> </div> And with Errors, it needs to look like this - Note the div with class "error" and the <p> tag. <div class="grid-26 append-2"> <div class="error"> <p>Please write your real name</p> <p class="noMarginBottom"> <label>First Name</label> <div class="jNiceInputWrapper"> <div class="jNiceInputInner"> <input type="text" class="text jNiceInput" name="name"/> </div> </div> </p> <span class="clear"/> </div> </div> My Validation code is very basic. $(document).ready(function(){ $("#contact_form").validate({ rules:{ name: { required: true } } }); }); This is my first venture into jQuery and form validation, so I'll be the first to say "I'm lost!" any help would be greatly appreciated. Thanks.

  • iPhone: Run method from another view

    - by Nic Hubbard
    I have two views that I am loading, the first is a view with an MKMapView, the second has a table view. I would like to access a method in the first views controller, from the second view. I have been told to use the delegate for this, but I can't get it right. In my app delegate, I have set up added properties for the class of my first view. Then, in my second view, I try to access the first view using the delegate: MyAppDelegate *mainDelegate = (MyAppDelegate*) [[UIApplication sharedApplication] delegate]; Then try: [mainDelegate.mapViewControllerClass myMethodToRun]; It seems to me that it should be calling the myMethodToRun method, which is in my map view. But, it does not work. What is wrong with what I am doing here? There must be a way to access a method of another view...

  • finding N contiguous zero bits in an integer to the left of the MSB from another

    - by James Morris
    First we find the MSB of the first integer, and then try to find a region of N contiguous zero bits within the second number which is to the left of the MSB from the first integer. Here is the C code for my solution: typedef unsigned int t; unsigned const t_bits = sizeof(t) * CHAR_BIT; _Bool test_fit_within_left_of_msb( unsigned width, t val1, t val2, unsigned* offset_result) { unsigned offbit = 0; unsigned msb = 0; t mask; t b; while(val1 >>= 1) ++msb; while(offbit + width < t_bits - msb) { mask = (((t)1 << width) - 1) << (t_bits - width - offbit); b = val2 & mask; if (!b) { *offset_result = offbit; return true; } if (offbit++) /* this conditional bothers me! */ b <<= offbit - 1; while(b <<= 1) offbit++; } return false; } Aside from faster ways of finding the MSB of the first integer, the commented test for a zero offbit seems a bit extraneous, but necessary to skip the highest bit of type t if it is set. I have also implemented similar algorithms but working to the right of the MSB of the first number, so they don't require this seemingly extra condition. How can I get rid of this extra condition, or even, are there far more optimal solutions?

  • Alternative Host (by DNS?) for Web Server Failure Protection

    - by Matrym
    I'm interested in having a second web host run a copy of my website, such that if my first host goes down, the traffic routes to the second host. Is this possible? My guess would be to add additional nameservers beyond the first two. I also suspect it's doable with no-ip.com, but I'm not clear on how that works, and if they would require me to leave my first host entirely?

  • Are there any tools to speed up Cocoa development?

    - by user262325
    I noticed that there is much repeated work to do when creating Cocoa source code. For example, if I set an instance for an object: NSMutableArray *infoArray; I need add code: @property (retain,nonatomic) NSMutableArray *infoArray; @synthesize infoArray; in - (void)dealloc { I also need add: [infoArray release]; Is there any tool that can automate this, perhaps by automatically paste or copy the source code and add the repeated code at right place?

  • Can I have two names for the same variable?

    - by Roman
    The short version of the question: I do: x = y. Then I change x, and y is unchanged. What I want is to "bind" x and y in such a way that I change y whenever I change x. The extended version (with some details): I wrote a class ("first" class) which generates objects of another class ("second" class). In more details, every object of the second class has a name as a unique identifier. I call a static method of the first class with a name of the object from the second class. The first class checks if such an object was already generated (if it is present in the static HashMap of the first class). If it is already there, it is returned. If it is not yet there, it is created, added to the HashMap and returned. And then I have the following problem. At some stage of my program, I take an object with a specific name from the HashMap of the first class. I do something with this object (for example change values of some fields). But the object in the HashMap does not see these changes! So, in fact, I do not "take" an object from the HashMap, I "create a copy" of this object and this is what I would like to avoid.

  • check if a line is valid or not in Java

    - by Adnan
    I would like to perform checking on the following: VALID LINES; /**/ some code */ some code /** dsfsdkf sd**/ NOT VALID LINES; /**/ //some code */ /***/ //somecode So basically if there is a line of code outside a comment it is valid, otherwise not. What would be the best way to tackle this kind of validation? Note: For */ I assume that the /* has been opened some lines before.

  • How is this statement making sense? (Sun's naming convention for Java variables)

    - by polygenelubricants
    I've been quoting this segment from Sun's document for the past few days, and only now do I stop and think about what it's saying, and I can't make sense out of it. Please keep in mind that English is not my first language. Naming conventions Variables: Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter. How is this making sense? Isn't this saying that class names are in mixed case with a lowercase first letter? Like I should name it class myClass? And class constants are also in mixed case with a lowercase first letter? Like I should name it Integer.maxValue? And is it really saying anything about how variables themselves should be named? Am I not parsing this properly or is this actually a blatant error?

  • Using C struct without including header file

    - by shams
    My basic problem is that I want to use some structs and functions defined in a header file by not including that header file in my code. The header file is generated by a tool. Since I don't have access to the header file, I can't include it in my program. Here's a simple example of my scenario: first.h #ifndef FIRST_H_GUARD #define FIRST_H_GUARD typedef struct ComplexS { float real; float imag; } Complex; Complex add(Complex a, Complex b); // Other structs and functions #endif first.c #include "first.h" Complex add(Complex a, Complex b) { Complex res; res.real = a.real + b.real; res.imag = a.imag + b.imag; return res; } my_program.c // I cannot/do not want to include the first.h header file here // but I want to use the structs and functions from the first.h #include <stdio.h> int main() { Complex a; a.real = 3; a.imag = 4; Complex b; b.real = 6; b.imag = 2; Complex c = add(a, b); printf("Result (%4.2f, %4.2f)\n", c.real, c.imag); return 0; } My intention is to build an executable for my_program and then use the linker to link up the executables. Is what I want to achieve possible in C?

  • How can I pivot these key+values rows into a table of complete entries?

    - by CodexArcanum
    Maybe I demand too much from SQL but I feel like this should be possible. I start with a list of key-value pairs, like this: '0:First, 1:Second, 2:Third, 3:Fourth' etc. I can split this up pretty easily with a two-step parse that gets me a table like: EntryNumber PairNumber Item 0 0 0 1 0 First 2 1 1 3 1 Second etc. Now, in the simple case of splitting the pairs into a pair of columns, it's fairly easy. I'm interested in the more advanced case where I might have multiple values per entry, like: '0:First:Fishing, 1:Second:Camping, 2:Third:Hiking' and such. In that generic case, I'd like to find a way to take my 3-column result table and somehow pivot it to have one row per entry and one column per value-part. So I want to turn this: EntryNumber PairNumber Item 0 0 0 1 0 First 2 0 Fishing 3 1 1 4 1 Second 5 1 Camping Into this: Entry [1] [2] [3] 0 0 First Fishing 1 1 Second Camping Is that just too much for SQL to handle, or is there a way? Pivots (even tricky dynamic pivots) seem like an answer, but I can't figure how to get that to work.

  • XSLT split text and preserve HTML tags

    - by Lycaon
    I have an xml that has a description node: <config> <desc>A <b>first</b> sentence here. The second sentence with some link <a href="myurl">The link</a>. The <u>third</u> one.</desc> </config> I am trying to split the sentences using dot as separator but keeping in the same time in the HTML output the eventual HTML tags. What I have so far is a template that splits the description but the HTML tags are lost in the output due to the normalize-space and substring-before functions. My current template is given below: <xsl:template name="output-tokens"> <xsl:param name="sourceText" /> <!-- Force a . at the end --> <xsl:variable name="newlist" select="concat(normalize-space($sourceText), ' ')" /> <!-- Check if we have really a point at the end --> <xsl:choose> <xsl:when test ="contains($newlist, '.')"> <!-- Find the first . in the string --> <xsl:variable name="first" select="substring-before($newlist, '.')" /> <!-- Get the remaining text --> <xsl:variable name="remaining" select="substring-after($newlist, '.')" /> <!-- Check if our string is not in fact a . or an empty string --> <xsl:if test="normalize-space($first)!='.' and normalize-space($first)!=''"> <p><xsl:value-of select="normalize-space($first)" />.</p> </xsl:if> <!-- Recursively apply the template for the remaining text --> <xsl:if test="$remaining"> <xsl:call-template name="output-tokens"> <xsl:with-param name="sourceText" select="$remaining" /> </xsl:call-template> </xsl:if> </xsl:when> <!--If no . was found --> <xsl:otherwise> <p> <!-- If the string does not contains a . then display the text but avoid displaying empty strings --> <xsl:if test="normalize-space($sourceText)!=''"> <xsl:value-of select="normalize-space($sourceText)" />. </xsl:if> </p> </xsl:otherwise> </xsl:choose> </xsl:template> and I am using it in the following manner: <xsl:template match="config"> <xsl:call-template name="output-tokens"> <xsl:with-param name="sourceText" select="desc" /> </xsl:call-template> </xsl:template> The expected output is: <p>A <b>first</b> sentence here.</p> <p>The second sentence with some link <a href="myurl">The link</a>.</p> <p>The <u>third</u> one.</p>
