• Rotating a child shape relative to its parent's orientation

  - by user1423893

  When rotating a shape using a quaternion value I also wish rotate its child shape. The parent and child shapes both start with different orientations but their relative orientations should always be the same. How can I use the difference between the previous and current quaternions of the parent shape in order to transform the child segment and rotate it relative to its parent shape? public Quaternion Orientation { get { return entity.Orientation; } set { Quaternion previousValue = entity.Orientation; entity.Orientation = value; // Use the difference between the quaternion values to update child orientation } }

• How do I Scroll parent page to top when child page is click within iframe?

  - by Evan

  Hello, When someone clicks on a link within an iframe (child page), how do I get the parent page to scroll to the top? The issue is the child page will remain in the same spot of the page, because the iframe has a lot of height larger than the parent page. Please note: the parent and child pages are on different sub domains. I created a demo to show this: http://www.apus.edu/_test/iframe/index.htm

• Prevent UIGestureRecognizer from firing selector more than once

  - by JK

  I utilize a UILongPressGestureRecognizer in my app. This is a continuous gesture recognizer which means it continuously fires the selector for the target it was initialized with. I would like the selector to be fired only once. I have tried to prevent further selectors being fired by setting the gesture recognizer's enabled property to Note the first time the selector is fired, but this only takes effect after the selector is fired again. How can I ensure the selector is fired only once?

• Check if a selector have a certain set of classes

  - by emilolsson

  Hello I'm trying to be able to check if a selector have a certain sets of classes. .hasClass() can only check if the selector has one class. And the .is() selector can look for multiple classes but will return true if the selector have at least one of the classes. But I wan't to achieve a way to check if a selector have both of the classes, and only if it has both of the classes do action. Any pointers?

• Iterate through all form fields within a specified DIV tag.

  - by user344255

  I need to be able to iterate through all the form fields within a specified DIV tag. Basically, any given DIV tag can have multiple form fields (which is easy enough to parse through), but it can also any number of tables or even additional DIV tags (adding additional levels of hierarchical layering). I've written a basic function that goes through each of the direct descendants of the parent node (in this case, the DIV tag) and it clears out its value. This part works fine. The problem is getting it to parse children when children (grandchildren) of their own. It winds up getting caught up in an infinite loop. In this case, I need be able to find all the form fields within DIV tag "panSomePanel", which will include some direct children (txtTextField1), but also some grandchildren who are within nested TABLE objects and/or nested DIV tags (radRadioButton, DESC_txtTextArea). Here is a sample DIV and its contents: <DIV id="panSomePanel"> <INPUT name="txtTextField1" type="text" id="txtTextField1" size="10"/><BR><BR> <TABLE id="tblRadioButtons" border="0"> <TR> <TD> <INPUT id="radRadioButton_0" type="radio" name="radRadioButton" value="1" /><LABEL for="radRadioButton_0">Value 1</LABEL> </TD> <TD> <INPUT id="radRadioButton_5" type="radio" name="radRadioButton" value="23" /><LABEL for="radRadioButton_5">Value 23</LABEL> </TD> </TR> <TR> <TD> <INPUT id="radRadioButton_1" type="radio" name="radRadioButton" value="2" /><LABEL for="radRadioButton_1">Value 2</LABEL> </TD> <TD> <INPUT id="radRadioButton_6" type="radio" name="radRadioButton" value="24" /><LABEL for="radRadioButton_6">Value 24</LABEL> </TD> </TR> <TR> <TD> <INPUT id="radRadioButton_2" type="radio" name="radRadioButton" value="3" /><LABEL for="radRadioButton_2">Value 3</LABEL> </TD> <TD> <INPUT id="radRadioButton_7" type="radio" name="radRadioButton" value="25" /><LABEL for="radRadioButton_7">Value 25</LABEL> </TD> </TR> <TR> <TD> <INPUT id="radRadioButton_3" type="radio" name="radRadioButton" value="21" /><LABEL for="radRadioButton_3">Value 21</LABEL> </TD> <TD> <INPUT id="radRadioButton_8" type="radio" name="radRadioButton" value="4" /><LABEL for="radRadioButton_8">Value 4</LABEL> </TD> </TR> <TR> <TD> <INPUT id="radRadioButton_4" type="radio" name="radRadioButton" value="22" /><LABEL for="radRadioButton_4">Value 22</LABEL> </TD> </TR> </TABLE> <DIV id="panAnotherPanel"><BR> <TABLE cellpadding="0" cellspacing="0" border="0" style="display:inline;vertical-align:top;"> <TR> <TD valign="top"> <TEXTAREA name="DESC:txtTextArea" rows="3" cols="48" id="DESC_txtTextArea"></TEXTAREA>&nbsp; </TD> <TD valign="top"><SPAN id="DESC_lblCharCount" style="font-size:8pt;"></SPAN> </TD> </TR> </TABLE> </DIV> </DIV> Here is the function I've written: function clearChildren(node) { var child; if (node.childNodes.length > 0) { child= node.firstChild; } while(child) { if (child.type == "text") { alert(child.id); child.value = ""; } else if (child.type == "checkbox") { child.checked = false; } else if (child.type == "radio") { alert(child.id); child.checked = false; } else if (child.type == "textarea") { child.innerText = ""; } //alert(child.childNodes.length); if (child.childNodes.length > 0) { var grandchild = child.firstChild; while (grandchild) { clearChildren(grandchild); } grandchild = grandchild.nextSibling; } child = child.nextSibling; } }

• Loading child entities with JPA on Google App Engine

  - by Phil H

  I am not able to get child entities to load once they are persisted on Google App Engine. I am certain that they are saving because I can see them in the datastore. For example if I have the following two entities. public class Parent implements Serializable{ @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String key; @OneToMany(cascade=CascadeType.ALL) private List<Child> children = new ArrayList<Child>(); //getters and setters } public class Child implements Serializable{ @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String key; private String name; @ManyToOne private Parent parent; //getters and setters } I can save the parent and a child just fine using the following: Parent parent = new Parent(); Child child = new Child(); child.setName("Child Object"); parent.getChildren().add(child); em.persist(parent); However when I try to load the parent and then try to access the children (I know GAE lazy loads) I do not get the child records. //parent already successfully loaded parent.getChildren.size(); // this returns 0 I've looked at tutorial after tutorial and nothing has worked so far. I'm using version 1.3.3.1 of the SDK. I've seen the problem mentioned on various blogs and even the App Engine forums but the answer is always JDO related. Am I doing something wrong or has anyone else had this problem and solved it for JPA?

• LINQ to XML: suppressing redundant namespace attribute in child nodes

  - by GSerg

  If a node belongs to a namespace, it's children by default belong to the same namespace. So there's no need to provide an xmlns attribute on each child, which is good. However. If I create two nodes like this: Dim parent = <parent xmlns="http://my.namespace.org"/> Dim child = <child xmlns="http://my.namespace.org">value</child> parent.Add(child) Console.WriteLine(parent.ToString) The result is this: <parent xmlns="http://my.namespace.org"> <child xmlns="http://my.namespace.org">value</child> </parent> But, if create them in a less convenient way: Dim parent = <parent xmlns="http://my.namespace.org"/> Dim child As New XElement(XName.Get("child", "http://my.namespace.org")) With {.Value = "value"} parent.Add(child) Console.WriteLine(parent.ToString) The result is more desirable: <parent xmlns="http://my.namespace.org"> <child>value</child> </parent> Obviously, I'd prefer to use the first way because it is so much more intuitive and easy to code. There's also another reason to not use method 2 -- sometimes I need to create nodes with XElement.Parse, parsing a string that contains an xmlns attribute, which produces exactly same results as method 1. So the question is -- how do I get the pretty output of method 2, creating nodes as in method 1? The only option I see is to create a method that would clone given XElement, effectively recreating it according to method 2 pattern, but that seems ugly. I'm looking for a more obvious solution I overlooked for some reason.

• JQuery: how to write a selector to find elements with a class ending with a given substring?

  - by curious1

  I use JQuery for my web application. I don't know how to write a selector for this situation. <a class="abc def xyz-delete-confirm efg">text</a> <a class="abc def delete-confirm">text</a> I need to find all links that has a class ending with "-delete-confirm" or has a class called "delete-confirm". I know how to handle the situation of having a class called "delete-confirm". How about the "-delete-confirm situation"? Can I have a single selector covering two situations? Thanks for any input! Regards.

• Python dictionary key missing

  - by Greg K

  I thought I'd put together a quick script to consolidate the CSS rules I have distributed across multiple CSS files, then I can minify it. I'm new to Python but figured this would be a good exercise to try a new language. My main loop isn't parsing the CSS as I thought it would. I populate a list with selectors parsed from the CSS files to return the CSS rules in order. Later in the script, the list contains an element that is not found in the dictionary. for line in self.file.readlines(): if self.hasSelector(line): selector = self.getSelector(line) if selector not in self.order: self.order.append(selector) elif selector and self.hasProperty(line): # rules.setdefault(selector,[]).append(self.getProperty(line)) property = self.getProperty(line) properties = [] if selector not in rules else rules[selector] if property not in properties: properties.append(property) rules[selector] = properties # print "%s :: %s" % (selector, "".join(rules[selector])) return rules Error encountered: $ css-combine combined.css test1.css test2.css Traceback (most recent call last): File "css-combine", line 108, in <module> c.run(outfile, stylesheets) File "css-combine", line 64, in run [(selector, rules[selector]) for selector in parser.order], KeyError: 'p' Swap the inputs: $ css-combine combined.css test2.css test1.css Traceback (most recent call last): File "css-combine", line 108, in <module> c.run(outfile, stylesheets) File "css-combine", line 64, in run [(selector, rules[selector]) for selector in parser.order], KeyError: '#header_.title' I've done some quirky things in the code like sub spaces for underscores in dictionary key names in case it was an issue - maybe this is a benign precaution? Depending on the order of the inputs, a different key cannot be found in the dictionary. The script: #!/usr/bin/env python import optparse import re class CssParser: def __init__(self): self.file = False self.order = [] # store rules assignment order def parse(self, rules = {}): if self.file == False: raise IOError("No file to parse") selector = False for line in self.file.readlines(): if self.hasSelector(line): selector = self.getSelector(line) if selector not in self.order: self.order.append(selector) elif selector and self.hasProperty(line): # rules.setdefault(selector,[]).append(self.getProperty(line)) property = self.getProperty(line) properties = [] if selector not in rules else rules[selector] if property not in properties: properties.append(property) rules[selector] = properties # print "%s :: %s" % (selector, "".join(rules[selector])) return rules def hasSelector(self, line): return True if re.search("^([#a-z,\.:\s]+){", line) else False def getSelector(self, line): s = re.search("^([#a-z,:\.\s]+){", line).group(1) return "_".join(s.strip().split()) def hasProperty(self, line): return True if re.search("^\s?[a-z-]+:[^;]+;", line) else False def getProperty(self, line): return re.search("([a-z-]+:[^;]+;)", line).group(1) class Consolidator: """Class to consolidate CSS rule attributes""" def run(self, outfile, files): parser = CssParser() rules = {} for file in files: try: parser.file = open(file) rules = parser.parse(rules) except IOError: print "Cannot read file: " + file finally: parser.file.close() self.serialize( [(selector, rules[selector]) for selector in parser.order], outfile ) def serialize(self, rules, outfile): try: f = open(outfile, "w") for rule in rules: f.write( "%s {\n\t%s\n}\n\n" % ( " ".join(rule[0].split("_")), "\n\t".join(rule[1]) ) ) except IOError: print "Cannot write output to: " + outfile finally: f.close() def init(): op = optparse.OptionParser( usage="Usage: %prog [options] <output file> <stylesheet1> " + "<stylesheet2> ... <stylesheetN>", description="Combine CSS rules spread across multiple " + "stylesheets into a single file" ) opts, args = op.parse_args() if len(args) < 3: if len(args) == 1: print "Error: No input files specified.\n" elif len(args) == 2: print "Error: One input file specified, nothing to combine.\n" op.print_help(); exit(-1) return [opts, args] if __name__ == '__main__': opts, args = init() outfile, stylesheets = [args[0], args[1:]] c = Consolidator() c.run(outfile, stylesheets) Test CSS file 1: body { background-color: #e7e7e7; } p { margin: 1em 0em; } File 2: body { font-size: 16px; } #header .title { font-family: Tahoma, Geneva, sans-serif; font-size: 1.9em; } #header .title a, #header .title a:hover { color: #f5f5f5; border-bottom: none; text-shadow: 2px 2px 3px rgba(0, 0, 0, 1); } Thanks in advance.

• selector for button not working

  - by user1662334

  I want to change the background of the button when the button is unclickable.I have used selector for that but it is not working in the case when the button remains unclickable. This is the selector file: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_enabled="false" android:drawable="@drawable/button_lightgrey" /> <item android:state_pressed="true" android:state_enabled="true" android:drawable="@drawable/button_blue"/> <item android:state_focused="true" android:drawable="@drawable/button_darkgreen" /> <item android:drawable="@drawable/button_lightgreen" /> </selector> This is the button where i am using this selector file: <Button android:id="@+id/PrevButton" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_centerInParent="true" android:layout_marginLeft="5.0dip" android:layout_weight="1.0" android:background="@drawable/ibtn" android:onClick="onPrevButtonClick" android:text="Prev" /> Please help me.All other functions are working in the selector file but only the unclickable button case is not working.Thanks

• MVVM - child windows and data contexts

  - by GlenH7

  Should a child window have it's own data context (View-Model) or use the data context of the parent? More broadly, should each View have its own View-Model? Are there are any rules to guide making that decision? What if the various View-Models will be accessing the same Model? I haven't been able to find any consistent guidance on my question. The MS definition of MVVM appears to be silent on child windows. For one example, I have created a warning message notification View. It really didn't need a data context since it was passed the message to display. But if I needed to fancy it up a bit, I would have tapped the parent's data context. I have run into another scenario that needs a child window and is more complicated than the notification box. The parent's View-Model is already getting cluttered, so I had planned on generating a dedicated VM for the child window. But I can't find any guidance on whether this is a good idea or what the potential consequences may be. FWIW, I happen to be working in Silverlight, but I don't know that this question is strictly a Silverlight issue.

• cpufreq-selector, cpufreq-info reporting wrong max speed

  - by dty

  Hi, I've just built a new machine with a Core i5-760 CPU. Max speed is 2.80GHz (turbo mode notwithstanding). I've also done a vanilla install of Ubuntu 10.10. I've added the cpufreq-selector applet to the top panel, and its menus only allow me to select up to 2.39GHz. If I select the "performance" governor, it also shows 2.39GHz. cpufreq-info reports: $ cpufreq-info cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.20 GHz - 2.39 GHz available frequency steps: 2.39 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz, 1.46 GHz, 1.33 GHz, 1.20 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.20 GHz and 2.39 GHz.

And ideally to report the actual speed when running in turbo mode too, but that's not critical. Edit: I should probably add that the BIOS (& Windows) are quite happy that it's a 2.80GHz CPU. Thanks.

• jquery selector for elements beside one another? [migrated]

  - by PaulHanak

  this SHOULD be simple, but I have been through the Jquery Selector help for about an hour now and nothing seems to be working. Help! I am basically trying to pull the text (an address) of a SPAN after a user clicks on the link next to it. Please note though, I will have about 10 on a page, so I cannot set a static address. It must be pulled when the user clicks. The html code: <a href="3" class="clicky">Click to Show Map</a> <span style="display: none" class="theaddy">123 Fake Street, Somewhere Else, 12341</span> So really, my question is, how do I grab the text from .theaddy when a user clicks on .clicky? As I said, I cannot use var propertyaddy = $(.theaddy).text(); because there are 10 of these addy's on the same page. I need some sort of "THIS" Next To kinda thing. I also tossed around the idea of placing the SPAN inside the A, but my efforts on that weren't working either. Thank you in advance for any help!

• OIM 11g - Multi Valued attribute reconciliation of a child form

  - by user604275

  This topic gives a brief description on how we can do reconciliation of a child form attribute which is also multi valued from a flat file . The format of the flat file is (an example): ManagementDomain1|Entitlement1|DIRECTORY SERVER,EMAIL ManagementDomain2|Entitlement2|EMAIL PROVIDER INSTANCE - UMS,EMAIL VERIFICATION In OIM there will be a parent form for fields Management domain and Entitlement.Reconciliation will assign Servers ( which are multi valued) to corresponding Management  Domain and Entitlement .In the flat file , multi valued fields are seperated by comma(,). In the design console, Create a form with 'Server Name' as a field and make it a child form . Open the corresponding Resource Object and add this field for reconcilitaion.While adding , choose 'Multivalued' check box. (please find attached screen shot on how to add it , Child Table.docx) Open process definiton and add child form fields for recociliation. Please click on the 'Create Reconcilitaion Profile' buttton on the resource object tab. The API methods used for child form reconciliation are : 1.           reconEventKey =   reconOpsIntf.createReconciliationEvent(resObjName, reconData,                                                            false); ·                                    ‘False’  here tells that we are creating the recon for a child table . 2.               2.       reconOpsIntf.providingAllMultiAttributeData(reconEventKey, RECON_FIELD_IN_RO, true);                RECON_FIELD_IN_RO is the field that we added in the Resource Object while adding for reconciliation, please refer the screen shot) 3.    reconOpsIntf.addDirectBulkMultiAttributeData(reconEventKey,RECON_FIELD_IN_RO, bulkChildDataMapList);                 bulkChildDataMapList  is coded as below :                 List<Map> bulkChildDataMapList = new ArrayList<Map>();                   for (int i = 0; i < stokens.length; i++) {                            Map<String, String> attributeMap = new HashMap<String, String>();                           String serverName = stokens[i].toUpperCase();                           attributeMap.put("Server Name", stokens[i]);                           bulkChildDataMapList.add(attributeMap);                         } 4                  4.       reconOpsIntf.finishReconciliationEvent(reconEventKey); 5.       reconOpsIntf.processReconciliationEvent(reconEventKey); Now, we have to register the plug-in, import metadata into MDS and then create a scheduled job to execute which will run the reconciliation.

• Accessing Instance Variables from NSTimer selector

  - by Timbo

  Firstly newbie question: What's the difference between a selector and a method? Secondly newbie question (who would have thought): I need to loop some code based on instance variables and pause between loops until some condition (of course based on instance variables) is met. I've looked at sleep, I've looked at NSThread. In both discussions working through those options many asked why don't I use NSTimer, so here I am. Ok so it's simple enough to get a method (selector? ) to fire on a schedule. Problem I have is that I don't know how to see instance variables I've set up outside the timer from within the code NSTimer fires. I need to see those variables from the NSTimer selector code as I 1) will be updating their values and 2) will set labels based on those values. Here's some code that shows the concept… eventually I'd invalidate the timers based on myVariable too, however I've excluded that for code clarity. MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance setMyVariable:0]; [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(doStuff) userInfo:nil repeats:YES]; [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(doSomeOtherStuff) userInfo:nil repeats:YES]; - (void) doStuff { [aMyClassInstance setMyVariable:11]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) doSomeOtherStuff { [aMyClassInstance setMyVariable:22]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) updateSomeUILabel:(NSNumber *)arg{ int value = [arg intValue]; someUILabel.text = [NSString stringWithFormat:@"myVariable = %d", value]; // Updates the UI with new instance variable values }

• What's the jquery CSS3 selector for excluding nested descendents?

  - by Danjah

  Per my SO question here, which has turned to jquery to solve this, but which may be worked back into YUI if I get my thinking straight, I need a selector to exclude descendents. The solution proposed says something like this: $( '.revealer:not(.revealer > .revealer)' ); To fit more accurately with my situation, because I have multiple HTML chunks to perform the same test on, I have updated it be: $( '#_revealerEl_0 .handle:not(#_revealerEl_0 .reveal .handle)' ); The HTML its selecting on (image there are numerous copies of this same chunk on a page, each needing to be treated alone - an id attribute is assigned to each 'revealer'): <div class="revealer"> <div class="hotspot"> <a class="handle" href="javascript:;">A</a> <div class="reveal"> <p>Content A.</p> </div> <div class="reveal"> <p>Content B.</p> <!-- nested revealer --> <div class="revealer"> <div class="hotspot"> <a class="handle" href="javascript:;">A</a> <div class="reveal"> <p>Sub-content A.</p> </div> <div class="reveal"> <p>Sub-content B.</p> </div> </div> </div> </div> </div> </div> In a nutshell: I need to target 'top level' handles within a 'hotspot', per revealer - and no nested descendents with the same class names. thanks, d

• Reading a child process's /proc/pid/mem file from the parent

  - by Amittai Aviram

  In the program below, I am trying to cause the following to happen: Process A assigns a value to a stack variable a. Process A (parent) creates process B (child) with PID child_pid. Process B calls function func1, passing a pointer to a. Process B changes the value of variable a through the pointer. Process B opens its /proc/self/mem file, seeks to the page containing a, and prints the new value of a. Process A (at the same time) opens /proc/child_pid/mem, seeks to the right page, and prints the new value of a. The problem is that, in step 6, the parent only sees the old value of a in /proc/child_pid/mem, while the child can indeed see the new value in its /proc/self/mem. Why is this the case? Is there any way that I can get the parent to to see the child's changes to its address space through the /proc filesystem? #include <fcntl.h> #include <stdbool.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <sys/wait.h> #include <unistd.h> #define PAGE_SIZE 0x1000 #define LOG_PAGE_SIZE 0xc #define PAGE_ROUND_DOWN(v) ((v) & (~(PAGE_SIZE - 1))) #define PAGE_ROUND_UP(v) (((v) + PAGE_SIZE - 1) & (~(PAGE_SIZE - 1))) #define OFFSET_IN_PAGE(v) ((v) & (PAGE_SIZE - 1)) # if defined ARCH && ARCH == 32 #define BP "ebp" #define SP "esp" #else #define BP "rbp" #define SP "rsp" #endif typedef struct arg_t { int a; } arg_t; void func1(void * data) { arg_t * arg_ptr = (arg_t *)data; printf("func1: old value: %d\n", arg_ptr->a); arg_ptr->a = 53; printf("func1: address: %p\n", &arg_ptr->a); printf("func1: new value: %d\n", arg_ptr->a); } void expore_proc_mem(void (*fn)(void *), void * data) { off_t frame_pointer, stack_start; char buffer[PAGE_SIZE]; const char * path = "/proc/self/mem"; int child_pid, status; int parent_to_child[2]; int child_to_parent[2]; arg_t * arg_ptr; off_t child_offset; asm volatile ("mov %%"BP", %0" : "=m" (frame_pointer)); stack_start = PAGE_ROUND_DOWN(frame_pointer); printf("Stack_start: %lx\n", (unsigned long)stack_start); arg_ptr = (arg_t *)data; child_offset = OFFSET_IN_PAGE((off_t)&arg_ptr->a); printf("Address of arg_ptr->a: %p\n", &arg_ptr->a); pipe(parent_to_child); pipe(child_to_parent); bool msg; int child_mem_fd; char child_path[0x20]; child_pid = fork(); if (child_pid == -1) { perror("fork"); exit(EXIT_FAILURE); } if (!child_pid) { close(child_to_parent[0]); close(parent_to_child[1]); printf("CHILD (pid %d, parent pid %d).\n", getpid(), getppid()); fn(data); msg = true; write(child_to_parent[1], &msg, 1); child_mem_fd = open("/proc/self/mem", O_RDONLY); if (child_mem_fd == -1) { perror("open (child)"); exit(EXIT_FAILURE); } printf("CHILD: child_mem_fd: %d\n", child_mem_fd); if (lseek(child_mem_fd, stack_start, SEEK_SET) == (off_t)-1) { perror("lseek"); exit(EXIT_FAILURE); } if (read(child_mem_fd, buffer, sizeof(buffer)) != sizeof(buffer)) { perror("read"); exit(EXIT_FAILURE); } printf("CHILD: new value %d\n", *(int *)(buffer + child_offset)); read(parent_to_child[0], &msg, 1); exit(EXIT_SUCCESS); } else { printf("PARENT (pid %d, child pid %d)\n", getpid(), child_pid); printf("PARENT: child_offset: %lx\n", child_offset); read(child_to_parent[0], &msg, 1); printf("PARENT: message from child: %d\n", msg); snprintf(child_path, 0x20, "/proc/%d/mem", child_pid); printf("PARENT: child_path: %s\n", child_path); child_mem_fd = open(path, O_RDONLY); if (child_mem_fd == -1) { perror("open (child)"); exit(EXIT_FAILURE); } printf("PARENT: child_mem_fd: %d\n", child_mem_fd); if (lseek(child_mem_fd, stack_start, SEEK_SET) == (off_t)-1) { perror("lseek"); exit(EXIT_FAILURE); } if (read(child_mem_fd, buffer, sizeof(buffer)) != sizeof(buffer)) { perror("read"); exit(EXIT_FAILURE); } printf("PARENT: new value %d\n", *(int *)(buffer + child_offset)); close(child_mem_fd); printf("ENDING CHILD PROCESS.\n"); write(parent_to_child[1], &msg, 1); if (waitpid(child_pid, &status, 0) == -1) { perror("waitpid"); exit(EXIT_FAILURE); } } } int main(void) { arg_t arg; arg.a = 42; printf("In main: address of arg.a: %p\n", &arg.a); explore_proc_mem(&func1, &arg.a); return EXIT_SUCCESS; } This program produces the output below.

• how to specify which child class this object belong to after retrieving from a hashmap?

  - by chandra wibowo

  hi everyone, i have a parent class called Course, and two child class PostgradCourse and UndergradCourse. i have a hashmap HashMap courses; i store all the postgradCourse and undergradCourse objects in the hashmap. i want to retrieve an undergradCourse object from the hashmap using the key. Course course = courses.get(courseCode); then i want to call a method in the UndergradCourse class, setUnits() method course.setUnits(); but the compiler say cannot find symbol- method setUnit() im pretty sure the problem is the compiler is looking for a method setUnit() in the Course class instead of UndergradCourse class i did this but its not working UndergradCourse course = courses.get(courseCode); results in incompatible type so how can i retrieve undergradCourse object from the hashmap as an undergradCourse object instead of course object? so then i can call a method inside the child class thanks in advance

• Passing class method as selector problem.

  - by Anoide

  Hi, I want to build a selector from a class method. I'm doing it this way: NavigationTreeActionHandler* handler=[NavigationTreeActionHandler self]; NavigationTreeNode* bombsNode=new NavigationTreeNode("Bombs","bigbomb.tif" ,handler,@selector(BigBombButtonPressed:)); I need to pass to NavigationTreeNode the target and the selector to the target method. I try to get the target using the self property of the class object (Don't know if htis is the correct way to do it). Then I get the selector for the class method I want to call on the class. Everything compiles ok but it fails when I use: [[handler class] instanceMethodSignatureForSelector:selector]; I get a nil and don't really know why... could anybody help please? Thanks in advance, Olson.
