  • calculater by using reverse polish notation and using a stack

    - by programmer
    hello everyone I have a segmentation fault ,can you help please? if i have this operater "3 5 +" that mean 3+5 and like "9 8 * 5 + 4 + sin", "sin(((9*8)+5)+4)" so my idea is check if the first and second are numbers and push theem in the stack then when i have operator i pop the numbers and make the calculation then push the answer again. ` typedef struct st_node { float val; struct st_node *next; } t_node; typedef t_node t_stack; // a function to allocate memory for a stack and returns the stack t_stack* fnewCell() { t_stack* ret; ret = (t_stack*) malloc(sizeof(t_stack)); return ret; } // a function to allocate memory for a stack, fills it with value v and pointer n , and returns the stack t_stack* fnewCellFilled(float v, t_stack* n) { t_stack* ret; ret = fnewCell(); ret->val = v; ret->next =n; return ret; } //function to initialize stack void initstack(t_stack** stack) { fnewCellFilled(0,NULL); } // add new cell void insrtHead(t_stack** head,float val) { *head = fnewCellFilled(val,*head); } //function to push the value v into the stack s void push(t_stack **s, float val) { insrtHead(s,val); } //function to pop a value from the stack and returns it int pop(t_stack **s) { t_stack* tmp; int ret; tmp = (*s)->next; ret = (*s)->val; free(*s); (*s) = tmp; return ret; } int isempty (t_stack *t) { return t == NULL; } //function to transfer a string(str) to int (value) //returns -1 when success , i otherwise int str2int(char *str,int *value) { int i; *value = 0; int sign=(str[0]=='-' ? -1 : 1); for(i=(str[0]=='-' ? 1 : 0);str[i]!=0;i++) { if(!(str[i]>=48 && str[i]<=57)) // Ascii char 0 to 9 return i; *value= *value*10+(str[i]-48); } *value = *value * sign; return -1; } //a function that takes a string, transfer it into integer and make operation using a stack void function(t_stack *stack, char *str) { char x[10]=" "; int y,j,i=0,z; printf("++\n"); if(str[i] != '\0') { strcpy(x, strtok(str, " ")); z= str2int(x, &y); if(z == -1) { push(&stack,y); i=i+2; } } while(str[i] != '\0') { strcpy(x, strtok(NULL, " ")); z= str2int(x, &y); if(z == -1) { printf("yes %d",y); push(&stack,y); i=i+2; } else { y=pop(&stack); j=pop(&stack); if(x[0] == '+' ) push(&stack,y+j); else if (x[0] == '-' ) push(&stack,j-y); else if(x[0] == '*' ) push(&stack,j*y); else if(x[0] == '/') push (&stack ,j/y); } } } int main() { t_stack *s; initstack(&s); char *str="3 5 +"; function(s,str); return 0; } `

  • Using MigLayout, why is a JButton following a JTable unresponsive and how to fix this?

    - by M. Joanis
    Hi everyone, I am having a mind-boggling problem regarding the use of a JButton following a JTable with MigLayout. It is totally unresponsive unless I push it far enough past the JTable (then it can behave correctly). I have tried running the code with both the MigLayout JAR of the version we use for end user products and with the very most recent one; same result. Here is a sample code reproducing the problem (Main.java): import java.awt.Dimension; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.JTextField; import javax.swing.table.DefaultTableModel; import net.miginfocom.swing.MigLayout; @SuppressWarnings("serial") public class Main extends JFrame { private JPanel panel; private JTextField textField; private JButton chooseButton; private JTable table; private JButton reloadButton; private final DefaultTableModel model = new DefaultTableModel() { @Override public boolean isCellEditable(int row, int column) { return false; } }; public Main() { panel = new JPanel(new MigLayout("debug", "[][grow][]")); setContentPane(panel); setDefaultCloseOperation(EXIT_ON_CLOSE); /*** First row ***/ // "File:" panel.add(new JLabel("File:")); // textField for filename textField = new JTextField("No file selected yet!"); textField.setEditable(false); panel.add(textField, "growx"); // "Choose..." button chooseButton = new JButton("Choose..."); panel.add(chooseButton, "wrap, sg buttons"); /*** Second row ***/ panel.add(new JLabel()); table = new JTable(model); model.setColumnIdentifiers(new String[] {"col title"}); JScrollPane scrollpane = new JScrollPane(table); Dimension scrollpaneDimension = new Dimension(125, 110); scrollpane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); table.setPreferredScrollableViewportSize(scrollpaneDimension); table.setFillsViewportHeight(true); panel.add(table.getTableHeader(), "grow"); panel.add(scrollpane, "grow"); reloadButton = new JButton("Reload"); panel.add(reloadButton, "top, wrap, sg buttons"); pack(); setVisible(true); } public static void main(String[] args) { new Main(); } } I suppose it has something to do with the table header and the table itself ending up in the same layout cell, but I'm really not sure of this. As I said, if I push the button far enough past the JTable, it will work again. If I drop it on the next row, it doesn't work, I have to move it down one more row. The only library you need in your workspace to run the code is MigLayout. Thank you all for your help, much appreciated! M. Joanis

  • Why are these divs not aligned and space between?

    - by acidzombie24
    Why isnt everything aligned? No yellow should be visible and no orange should be visible except for the right side and bottom left where theres space for another image. Basically my images are pretty much aligned to the center (i have other pics not in this example which is easier to see). However in this case when i have 150px height image the 150 width seems start lower. Also why are there spaces in between <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>ldfk;sd</title> <style type="text/css"> div.ImgGallery { max-width: 630px; background: orange; } .ImgGallery div { display: inline; } /* http://www.brunildo.org/test/img_center.html */ .ImgGallery div div { display: table-cell; text-align: center; background: gray; width: 150px; height: 150px; } .ImgGallery div{ background: yellow; vertical-align: middle; } //.ImgGallery div div :nth-child(2n+1) { background: red; } .ImgGallery * { vertical-align: middle; } .ImgGallery a { display: block; } .ImgGallery a * { border-style: none; } </style> </head> <div class="smallGallery"> <div class="ImgGallery"> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="b.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="b.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> <div><div><a href="http://google.com"><img src="a.jpg" alt="a.jpg"></a></div></div> </div></div> </body></html>

    - by user325160
    Hello everyone, So I am trying to fill in Values "A-Z, 0-9" in a 2007 excel macro in four different locations (I am trying to put A-Z and 0-9 in cells: a1 to d9, e1 to h9, a10 to d18, and e10 to h18).

So is there a way to make it so that I can get the values A-Z and 0-9 in the other cells I specified above? Thank you.

  • DTGridView losing content while scrolling

    - by Wim Haanstra
    I am using DTGridView from the DTKit by Daniel Tull. I implemented it in a very simple ViewController and the test I am doing is to place a button in the last row of the grid, which should add another row to the grid (and therefor moving the button to a row beneath it). The problem is, when I click the button a couple of times and then start scrolling, the grid seems to lose its content. As I am not completly sure this is a bug in the grid, but more in my code, I hope you guys can help me out and track down the bug. First I have my header file, which is quite simple, because this is a test: #import <UIKit/UIKit.h> #import "DTGridView.h" @interface TestController : UIViewController <DTGridViewDelegate, DTGridViewDataSource> { DTGridView* thumbGrid; } @end I declare a DTGridView, which will be my grid, where I want to put content in. Now, my code file: #import "TestController.h" @implementation TestController int rows = 1; - (NSInteger)numberOfRowsInGridView:(DTGridView *)gridView { return rows; } - (NSInteger)numberOfColumnsInGridView:(DTGridView *)gridView forRowWithIndex:(NSInteger)index { if (index == rows - 1) return 1; else return 3; } - (CGFloat)gridView:(DTGridView *)gridView heightForRow:(NSInteger)rowIndex { return 57.0f; } - (CGFloat)gridView:(DTGridView *)gridView widthForCellAtRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { if (rowIndex == rows - 1) return 320.0f; else return 106.6f; } - (DTGridViewCell *)gridView:(DTGridView *)gridView viewForRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { DTGridViewCell *view = [[gridView dequeueReusableCellWithIdentifier:@"thumbcell"] retain]; if (!view) view = [[DTGridViewCell alloc] initWithReuseIdentifier:@"thumbcell"]; if (rowIndex == rows - 1) { UIButton* btnLoadMoreItem = [[UIButton alloc] initWithFrame:CGRectMake(10, 0, 301, 57)]; [btnLoadMoreItem setTitle:[NSString stringWithFormat:@"Button %d", rowIndex] forState:UIControlStateNormal]; [btnLoadMoreItem.titleLabel setFont:[UIFont boldSystemFontOfSize:20]]; [btnLoadMoreItem setBackgroundImage:[[UIImage imageNamed:@"big-green-button.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; [btnLoadMoreItem addTarget:self action:@selector(selectLoadMoreItems:) forControlEvents:UIControlEventTouchUpInside]; [view addSubview:btnLoadMoreItem]; [btnLoadMoreItem release]; } else { UILabel* label = [[UILabel alloc] initWithFrame:CGRectMake(10,0,100,57)]; label.text = [NSString stringWithFormat:@"%d x %d", rowIndex, columnIndex]; [view addSubview:label]; [label release]; } return [view autorelease]; } - (void) selectLoadMoreItems:(id) sender { rows++; [thumbGrid setNeedsDisplay]; } - (void)viewDidLoad { [super viewDidLoad]; thumbGrid = [[DTGridView alloc] initWithFrame:CGRectMake(0,0, 320, 320)]; thumbGrid.dataSource = self; thumbGrid.gridDelegate = self; [self.view addSubview:thumbGrid]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end I implement all the methods for the DataSource, which seem to work. The grid is filled with as many rows as my int 'rows' ( +1 ) has. The last row does NOT contain 3 columns, but just one. That cell contains a button which (when pressed) adds 1 to the 'rows' integer. The problem starts, when it starts reusing cells (I am guessing) and content start disappearing. When I scroll back up, the UILabels I am putting in the cells are gone. Is there some bug, code error, mistake, dumb-ass-move I am missing here? Hope anyone can help.

  • CSS: Labels in table columns

    - by hello
    Hello. BACKGROUND: I would like to have small labels in columns of a table. I'm using some implemented parts of HTML5/CSS3 in my project, and this section specifically is for mobile devices. While both facts are not necessarily relevant, the bottom line is that I don't have to support Internet Explorer or even Firefox for that matter (just WebKit). THE PROBLEM With my current CSS approach, the vertical padding of the cell comes from the <span element (set to display: block with top/bottom margins), which contains the "value" of the column. As a result there's no padding when the <span> is empty or missing (no value) and the label is not in place. The "full" coulmns should give you the idea of where I want the labels to be, even if there's no value, and the <span> is not there. I realize that I could use "non-breaking-space", but I would really like to avoid it. I wonder if any of you have a fix / better way to do this? current code is below. Thank you for any help. <!DOCTYPE html> <html lang="en"> <head> <title>ah</title> <style> body { width: 320px; } /* TABLE */ table { width: 100%; border-collapse: collapse; font-family: arial; } th, td { border: 1px solid #ccc; border-width: 0px 0px 1px 1px; } th:last-child, td:last-child { border-right-width: 1px; } tr:first-child th { border-top-width: 1px; background: #efefef; } /* RELEVANT STUFF */ td { padding: 3px; } td sup { display: block; } td span { display: block; margin: 3px 0px; text-align: center; } </style> </head> <body> <table> <tr> <th colspan="3">something</th> </tr> <tr> <td><sup>some label</sup><span>any content</span></td> <td><sup>some label</sup><span>any content</span></td> <td><sup>some label</sup><span></span></td><!-- No content, just a label --> </tr> </table> </body> </html>

  • iphone sdk - problem pasting into current text location

    - by norskben
    Hi guys I'm trying to paste text right into where the cursor currently is. I have been trying to do what it says at: - http://dev.ragfield.com/2009/09/insert-text-at-current-cursor-location.html The main deal is that I can't just go textbox1.text (etc) because the textfield is in the middle of a custom cell. I want to just have some text added to where the cursor is (when I press a custom key on a keyboard). -I just want to paste a decimal into the textbox... The error I get is: 2010-05-15 22:37:20.797 PageControl[37962:207] * -[MyDetailController paste:]: unrecognized selector sent to instance 0x1973d10 2010-05-15 22:37:20.797 PageControl[37962:207] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[MyDetailController paste:]: unrecognized selector sent to instance 0x1973d10' Note: I have access to the textfield tag (if that helps?)

  • Objective-C NSArray NEWBIE Question:

    - by clearbrian
    Hi I have a weird problems with NSArray where some of the members of the objects in my array are going out of scope but not the others: I have a simple object called Section. It has 3 members. @interface Section : NSObject { NSNumber *section_Id; NSNumber *routeId; NSString *startLocationName; } @property(nonatomic,retain) NSNumber *section_Id; @property(nonatomic,retain) NSNumber *routeId; @property(nonatomic,retain) NSString *startLocationName; @end @implementation Section @synthesize section_Id; @synthesize routeId; @synthesize startLocationName; //Some static finder methods to get list of Sections from the db + (NSMutableArray *) findAllSections:{ - (void)dealloc { [section_Id release]; [routeId release]; [startLocationName release]; [super dealloc]; } @end I fill it from a database in a method called findAllSection self.sections = [Section findAllSections]; In find all sections I create some local variables fill them with data from db. NSNumber *secId = [NSNumber numberWithInt:id_section]; NSNumber *rteId = [NSNumber numberWithInt:id_route]; NSString *startName = @""; Then create a new Section and store these local variable's data in the Section Section *section = [[Section alloc] init]; section.section_Id = secId; section.routeId = rteId; section.startLocationName = startName; Then I add the section to the array [sectionsArray addObject:section]; Then I clean up, releasing local variables and the section I added to the array [secId release]; [rteId release]; [startName release]; [locEnd_name release]; [section release]; In a loop repeat for all Sections (release local variables and section is done in every loop) The method returns and I check the array and all the Sections are there. I cant seem to dig further down to see the values of the Section objects in the array (is this possible) Later I try and retrieve one of the Sections I get it from the array Section * section = [self.sections objectAtIndex:row]; Then check the value NSLog(@" SECTION SELECTED:%@",section.section_Id); BUT call to section.section_Id crashed as section.section_Id is out of scope. I check the other members of this Section object and theyre ok. After some trial and error I find that by commenting out the release of the member variable the object is OK. //[secId release]; [rteId release]; [startName release]; [locEnd_name release]; [section release]; My questions are: Am I cleaning up ok? Should I release the object added to an array and the local variable in the function? Is my dealloc ok in Section? Does this code look ok and should I be looking elsewhere for the problem? I'm not doing anything complicated just filling array from DB use it in Table Cell. If its a stupid mistake then tell me (I did put NEWBIE on the question so dont be shocked it was asked) I can comment out the release but would prefer to know why or if code looks ok then ill need further digging. the only place that secId is released is in the dealloc. Thanks

  • Technology to communicate with someone with expressive aphasia?

    - by rascher
    A family member had a stroke a few years back and now has expressive aphasia. She understands what is said to her, is cognitive of what is going on, but cannot express herself. She is able to respond to yes/no questions (do you want to go shopping? are you looking for your earrings?) She is not, however, able to read (English is not her native language and she hasn't read Hindi for decades.) I am the technologist in the family, and I intend to come up with something to help us communicate. The idea is to have some sort of picture book where she can point to what she wants. My first question: does some sort of assistive technology for people with expressive aphasia already exist? These can be hardware or software devices? If not, then such a software doesn't seem difficult to write. My initial thought is to have an interface with pictures - maybe separated by category (food, shopping) - where she can point to an individual picture to indicate what she needs. We could easily add more items with such a software, and we could have an interface where she (or we) could "flip pages". Which suggests that the best solution would use a touch screen rather than a mouse. It would be really difficult to train her to aim a mouse or find keys on a keyboard. We're thinking of maybe getting a tablet and writing some basic software. But tablets computers are expensive and fragile - I'm not sure if it would be able to stand spills or being knocked about in a nursing home. So my next question: what kind of tablet-like devices are out there which I can program on? I don't know anything about hardware, but if there is something then we could special-order it. What would be safe and durable for such a project? We could do something on an iPod or cell phone, but I feel like that interface would be too small. Finally, does anyone here have experience with this kind of assistive technology? Things I might not anticipate when designing such a system? edit I've added a (pretty hefty!) bounty. I'd kinda like to open this question up to any suggestions, comments, and experiences that people might have. This is a pretty real and important project, so while we will (are working on) a solution, any insights would be particularly helpful. Right now the plan is to mount a screen in her room. We'll either teach her to use a trackball or use a touch-screen panel, after seeing what she is able to use with a simple prototype. Then software akin to an old "hypercard" deck: ---------------------------------------------------------------- | -------------- -------------- | | | Clothes | | Food | ... | | -------------- -------------- | | | | Pic of item 1 Pic of item 2 Pic of item 3 | | | | | | | | | | Pic of item 4 Pic of item 5 Pic of item 6 | | | | | | | | | | <-Back Next-> | ---------------------------------------------------------------- commentcommentcomment!

  • iPhone: Repeating Rows in Each Section of Grouped UITableview

    - by Rank Beginner
    I'm trying to learn how to use the UITableView in conjunction with a SQLite back end. My issue is that I've gotten the table to populate with the records from the database, however I'm having a problem with the section titles. I am not able to figure out the proper set up for this, and I'm repeating all tasks under each section. The table looks like this. The groups field is where I'm trying to pull the section title from. TaskID groups TaskName sched lastCompleted nextCompleted success 1 Household laundry 3 03/19/2010 03/22/2010 y 1 Automotive Change oil 3 03/20/2010 03/23/2010 y In my viewDidLoad Method, I create an array from each column in the table like below. //Create and initialize arrays from table columns //______________________________________________________________________________________ ids =[[NSMutableArray alloc] init]; tasks =[[NSMutableArray alloc] init]; sched =[[NSMutableArray alloc] init]; lastComplete =[[NSMutableArray alloc] init]; nextComplete =[[NSMutableArray alloc] init]; weight =[[NSMutableArray alloc] init]; success =[[NSMutableArray alloc] init]; group =[[NSMutableArray alloc] init]; // Bind them to the data //______________________________________________________________________________________ NSString *query = [NSString stringWithFormat:@"SELECT * FROM Tasks ORDER BY nextComplete "]; sqlite3_stmt *statement; if (sqlite3_prepare_v2( database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { [ids addObject:[NSString stringWithFormat:@"%i",(int*) sqlite3_column_int(statement, 0)]]; [group addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 1)]]; [tasks addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 2)]]; [sched addObject:[NSString stringWithFormat:@"%i",(int*) sqlite3_column_int(statement, 3)]]; [lastComplete addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 4)]]; [nextComplete addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 5)]]; [success addObject:[NSString stringWithFormat:@"%s",(char*) sqlite3_column_text(statement, 6)]]; [weight addObject:[NSString stringWithFormat:@"%i",(int*) sqlite3_column_int(statement, 7)]]; } sqlite3_finalize(statement); } In the table method:cellForRowAtIndexPath, I create controls on the fly and set their text properties to objects in the array. Below is a sample, I can provide more but am already working on a book here... :) /create the task label NSString *tmpMessage; tmpMessage = [NSString stringWithFormat:@"%@ every %@ days, for %@ points",[tasks objectAtIndex:indexPath.row],[sched objectAtIndex:indexPath.row],[weight objectAtIndex:indexPath.row]]; CGRect schedLabelRect = CGRectMake(0, 0, 250, 15); UILabel *lblSched = [[UILabel alloc] initWithFrame:schedLabelRect]; lblSched.textAlignment = UITextAlignmentLeft; lblSched.text = tmpMessage; lblSched.font = [UIFont boldSystemFontOfSize:10]; [cell.contentView addSubview: lblSched]; [lblSched release]; My numberOfSectionsInTableView method looks like this // Figure out how many sections there are by a distinct count of the groups field // The groups are entered by user when creating tasks //______________________________________________________________________________________ NSString *groupquery = [NSString stringWithFormat:@"SELECT COUNT(DISTINCT groups) as Sum FROM Tasks"]; int sum; sqlite3_stmt *statement; if (sqlite3_prepare_v2( database, [groupquery UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { sum = sqlite3_column_int(statement, 0); } sqlite3_finalize(statement); } if (sum=0) { return 1; } return 2; } I know I'm going wrong here but this is all that's in my numberOfRowsInSection method return [ids count];

  • Open XML SDK 2.0 - Split table to new power point slide when content flows off current slide

    - by amurra
    I have a bunch of data that I need to export from a website to a power point presentation and have been using Open XML SDK 2.0 to perform this task. I have a power point presentation that I am putting through Open XML SDK 2.0 Productivity Tool to generate the template code that I can use to recreate the export. On one of those slides I have a table and the requirement is to add data to that table and break that table across multiple slides if the table exceeds the bottom of the slide. The approach I have taken is to determine the height of the table and if it exceeds the height of the slide, move that new content into the next slide. I have read Bryan and Jones blog on adding repeating data to a power point slide, but my scenario is a little different. They use the following code: A.Table tbl = current.Slide.Descendants<A.Table>().First(); A.TableRow tr = new A.TableRow(); tr.Height = heightInEmu; tr.Append(CreateDrawingCell(imageRel + imageRelId)); tr.Append(CreateTextCell(category)); tr.Append(CreateTextCell(subcategory)); tr.Append(CreateTextCell(model)); tr.Append(CreateTextCell(price.ToString())); tbl.Append(tr); imageRelId++; This won't work for me since they know what height to set the table row to since it will be the height of the image, but when adding in different amounts of text I do not know the height ahead of time so I just set tr.Heightto a default value. Here is my attempt at figuring at the table height: A.Table tbl = tableSlide.Slide.Descendants<A.Table>().First(); A.TableRow tr = new A.TableRow(); tr.Height = 370840L; tr.Append(PowerPointUtilities.CreateTextCell("This"); tr.Append(PowerPointUtilities.CreateTextCell("is")); tr.Append(PowerPointUtilities.CreateTextCell("a")); tr.Append(PowerPointUtilities.CreateTextCell("test")); tr.Append(PowerPointUtilities.CreateTextCell("Test")); tbl.Append(tr); tableSlide.Slide.Save(); long tableHeight = PowerPointUtilities.TableHeight(tbl); Here are the helper methods: public static A.TableCell CreateTextCell(string text) { A.TableCell tableCell = new A.TableCell( new A.TextBody(new A.BodyProperties(), new A.Paragraph(new A.Run(new A.Text(text)))), new A.TableCellProperties()); return tableCell; } public static Int64Value TableHeight(A.Table table) { long height = 0; foreach (var row in table.Descendants<A.TableRow>() .Where(h => h.Height.HasValue)) { height += row.Height.Value; } return height; } This correctly adds the new table row to the existing table, but when I try and get the height of the table, it returns the original height and not the new height. The new height meaning the default height I initially set and not the height after a large amount of text has been inserted. It seems the height only gets readjusted when it is opened in power point. I have also tried accessing the height of the largest table cell in the row, but can't seem to find the right property to perform that task. My question is how do you determine the height of a dynamically added table row since it doesn't seem to update the height of the row until it is opened in power point? Any other ways to determine when to split content to another slide while using Open XML SDK 2.0? I'm open to any suggestion on a better approach someone might have taken since there isn't much documentation on this subject.

  • Wrong background colors in Swing ListCellRenderer

    - by Johannes Rössel
    I'm currently trying to write a custom ListCellRenderer for a JList. Unfortunately, nearly all examples simply use DefaultListCellRenderer as a JLabel and be done with it; I needed a JPanel, however (since I need to display a little more info than just an icon and one line of text). Now I have a problem with the background colors, specifically with the Nimbus PLAF. Seemingly the background color I get from list.getBackground() is white, but paints as a shade of gray (or blueish gray). Outputting the color I get yields the following: Background color: DerivedColor(color=255,255,255 parent=nimbusLightBackground offsets=0.0,0.0,0.0,0 pColor=255,255,255 However, as can be seen, this isn't what gets painted. It obviously works fine for the selected item. Currently I even have every component I put into the JPanel the cell renderer returns set to opaque and with the correct foreground and background colors—to no avail. Any ideas what I'm doing wrong here? ETA: Example code which hopefully runs. public class ParameterListCellRenderer implements ListCellRenderer { @Override public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { // some values we need Border border = null; Color foreground, background; if (isSelected) { background = list.getSelectionBackground(); foreground = list.getSelectionForeground(); } else { background = list.getBackground(); foreground = list.getForeground(); } if (cellHasFocus) { if (isSelected) { border = UIManager.getBorder("List.focusSelectedCellHighlightBorder"); } if (border == null) { border = UIManager.getBorder("List.focusCellHighlightBorder"); } } else { border = UIManager.getBorder("List.cellNoFocusBorder"); } System.out.println("Background color: " + background.toString()); JPanel outerPanel = new JPanel(new BorderLayout()); setProperties(outerPanel, foreground, background); outerPanel.setBorder(border); JLabel nameLabel = new JLabel("Factory name here"); setProperties(nameLabel, foreground, background); outerPanel.add(nameLabel, BorderLayout.PAGE_START); Box innerPanel = new Box(BoxLayout.PAGE_AXIS); setProperties(innerPanel, foreground, background); innerPanel.setAlignmentX(Box.LEFT_ALIGNMENT); innerPanel.setBorder(BorderFactory.createEmptyBorder(0, 10, 0, 0)); JLabel label = new JLabel("param: value"); label.setFont(label.getFont().deriveFont( AffineTransform.getScaleInstance(0.95, 0.95))); setProperties(label, foreground, background); innerPanel.add(label); outerPanel.add(innerPanel, BorderLayout.CENTER); return outerPanel; } private void setProperties(JComponent component, Color foreground, Color background) { component.setOpaque(true); component.setForeground(foreground); component.setBackground(background); } } The weird thing is, if I do if (isSelected) { background = new Color(list.getSelectionBackground().getRGB()); foreground = new Color(list.getSelectionForeground().getRGB()); } else { background = new Color(list.getBackground().getRGB()); foreground = new Color(list.getForeground().getRGB()); } it magically works. So maybe the DerivedColor with nimbusLightBackground I'm getting there may have trouble?

  • mySQL to XLS using PHP?

    Hi guys, how can I create a .XLS document from a mySQL table using PHP? I have tried just about everything, with no success.

  • DataTable to JSON

    - by Joel Coehoorn
    I recently needed to serialize a datatable to JSON. Where I'm at we're still on .Net 2.0, so I can't use the JSON serializer in .Net 3.5. I figured this must have been done before, so I went looking online and found a number of different options. Some of them depend on an additional library, which I would have a hard time pushing through here. Others require first converting to List<Dictionary<>>, which seemed a little awkward and needless. Another treated all values like a string. For one reason or another I couldn't really get behind any of them, so I decided to roll my own, which is posted below. As you can see from reading the //TODO comments, it's incomplete in a few places. This code is already in production here, so it does "work" in the basic sense. The places where it's incomplete are places where we know our production data won't currently hit it (no timespans or byte arrays in the db). The reason I'm posting here is that I feel like this can be a little better, and I'd like help finishing and improving this code. Any input welcome. public static class JSONHelper { public static string FromDataTable(DataTable dt) { string rowDelimiter = ""; StringBuilder result = new StringBuilder("["); foreach (DataRow row in dt.Rows) { result.Append(rowDelimiter); result.Append(FromDataRow(row)); rowDelimiter = ","; } result.Append("]"); return result.ToString(); } public static string FromDataRow(DataRow row) { DataColumnCollection cols = row.Table.Columns; string colDelimiter = ""; StringBuilder result = new StringBuilder("{"); for (int i = 0; i < cols.Count; i++) { // use index rather than foreach, so we can use the index for both the row and cols collection result.Append(colDelimiter).Append("\"") .Append(cols[i].ColumnName).Append("\":") .Append(JSONValueFromDataRowObject(row[i], cols[i].DataType)); colDelimiter = ","; } result.Append("}"); return result.ToString(); } // possible types: // http://msdn.microsoft.com/en-us/library/system.data.datacolumn.datatype(VS.80).aspx private static Type[] numeric = new Type[] {typeof(byte), typeof(decimal), typeof(double), typeof(Int16), typeof(Int32), typeof(SByte), typeof(Single), typeof(UInt16), typeof(UInt32), typeof(UInt64)}; // I don't want to rebuild this value for every date cell in the table private static long EpochTicks = new DateTime(1970, 1, 1).Ticks; private static string JSONValueFromDataRowObject(object value, Type DataType) { // null if (value == DBNull.Value) return "null"; // numeric if (Array.IndexOf(numeric, DataType) > -1) return value.ToString(); // TODO: eventually want to use a stricter format // boolean if (DataType == typeof(bool)) return ((bool)value) ?

  • Saving a .xls file with fwrite

    - by kielie
    hi guys, I have to create a script that takes a mySQL table, and exports it into .XSL format, and then saves that file into a specified folder on the web host. I got it working, but now I can't seem to get it to automatically save the file to the location without prompting the user.

Here is the original code, as I found it, any help would be greatly appreciated. :-) Thanx in advance. :-)

  • Passing a variable from Excel 2007 Custom Task Pane to Hosted PowerShell

    - by Uros Calakovic
    I am testing PowerShell hosting using C#. Here is a console application that works: using System; using System.Collections; using System.Collections.Generic; using System.Collections.ObjectModel; using System.Management.Automation; using System.Management.Automation.Runspaces; using Microsoft.Office.Interop.Excel; namespace ConsoleApplication3 { class Program { static void Main() { Application app = new Application(); app.Visible = true; app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Runspace runspace = RunspaceFactory.CreateRunspace(); runspace.Open(); runspace.SessionStateProxy.SetVariable("Application", app); Pipeline pipeline = runspace.CreatePipeline("$Application"); Collection<PSObject> results = null; try { results = pipeline.Invoke(); foreach (PSObject pob in results) { Console.WriteLine(pob); } } catch (RuntimeException re) { Console.WriteLine(re.GetType().Name); Console.WriteLine(re.Message); } } } } I first create an Excel.Application instance and pass it to the hosted PowerShell instance as a varible named $Application. This works and I can use this variable as if Excel.Application was created from within PowerShell. I next created an Excel addin using VS 2008 and added a user control with two text boxes and a button to the addin (the user control appears as a custom task pane when Excel starts). The idea was this: when I click the button a hosted PowerShell instance is created and I can pass to it the current Excel.Application instance as a variable, just like in the first sample, so I can use this variable to automate Excel from PowerShell (one text box would be used for input and the other one for output. Here is the code: using System; using System.Windows.Forms; using System.Management.Automation; using System.Management.Automation.Runspaces; using System.Collections.ObjectModel; using Microsoft.Office.Interop.Excel; namespace POSHAddin { public partial class POSHControl : UserControl { public POSHControl() { InitializeComponent(); } private void btnRun_Click(object sender, EventArgs e) { txtOutput.Clear(); Microsoft.Office.Interop.Excel.Application app = Globals.ThisAddIn.Application; Runspace runspace = RunspaceFactory.CreateRunspace(); runspace.Open(); runspace.SessionStateProxy.SetVariable("Application", app); Pipeline pipeline = runspace.CreatePipeline( "$Application | Get-Member | Out-String"); app.ActiveCell.Value2 = "Test"; Collection<PSObject> results = null; try { results = pipeline.Invoke(); foreach (PSObject pob in results) { txtOutput.Text += pob.ToString() + "-"; } } catch (RuntimeException re) { txtOutput.Text += re.GetType().Name; txtOutput.Text += re.Message; } } } } The code is similar to the first sample, except that the current Excel.Application instance is available to the addin via Globals.ThisAddIn.Application (VSTO generated) and I can see that it is really a Microsoft.Office.Interop.Excel.Application instance because I can use things like app.ActiveCell.Value2 = "Test" (this actually puts the text into the active cell). But when I pass the Excel.Application instance to the PowerShell instance what gets there is an instance of System.__ComObject and I can't figure out how to cast it to Excel.Application. When I examine the variable from PowerShell using $Application | Get-Member this is the output I get in the second text box: TypeName: System.__ComObject Name MemberType Definition ---- ---------- ---------- CreateObjRef Method System.Runtime.Remoting.ObjRef CreateObj... Equals Method System.Boolean Equals(Object obj) GetHashCode Method System.Int32 GetHashCode() GetLifetimeService Method System.Object GetLifetimeService() GetType Method System.Type GetType() InitializeLifetimeService Method System.Object InitializeLifetimeService() ToString Method System.String ToString() My question is how can I pass an instance of Microsoft.Office.Interop.Excel.Application from a VSTO generated Excel 2007 addin to a hosted PowerShell instance, so I can manipulate it from PowerShell? (I have previously posted the question in the Microsoft C# forum without an answer)

  • C++: Declaration of template class member specialization (+ Doxygen bonus question!)

    - by Ziv
    When I specialize a (static) member function/constant in a template class, I'm confused as to where the declaration is meant to go. Here's an example of what I what to do - yoinked directly from IBM's reference on template specialization: template<class T> class X { public: static T v; static void f(T); }; template<class T> T X<T>::v = 0; template<class T> void X<T>::f(T arg) { v = arg; } template<> char* X<char*>::v = "Hello"; template<> void X<float>::f(float arg) { v = arg * 2; } int main() { X<char*> a, b; X<float> c; c.f(10); // X<float>::v now set to 20 } The question is, how do I divide this into header/cpp files? The generic implementation is obviously in the header, but what about the specialization? It can't go in the header file, because it's concrete, leading to multiple definition. But if it goes into the .cpp file, is code which calls X::f() aware of the specialization, or might it rely on the generic X::f()? So far I've got the specialization in the .cpp only, with no declaration in the header. I'm not having trouble compiling or even running my code (on gcc, don't remember the version at the moment), and it behaves as expected - recognizing the specialization. But A) I'm not sure this is correct, and I'd like to know what is, and B) my Doxygen documentation comes out wonky and very misleading (more on that in a moment). What seems most natural to me would be something like this, declaring the specialization in the header and defining it in the .cpp: ===XClass.hpp=== #ifndef XCLASS_HPP #define XCLASS_HPP template<class T> class X { public: static T v; static void f(T); }; template<class T> T X<T>::v = 0; template<class T> void X<T>::f(T arg) { v = arg; } /* declaration of specialized functions */ template<> char* X<char*>::v; template<> void X<float>::f(float arg); #endif ===XClass.cpp=== #include <XClass.hpp> /* concrete implementation of specialized functions */ template<> char* X<char*>::v = "Hello"; template<> void X<float>::f(float arg) { v = arg * 2; } ...but I have no idea if this is correct. The most immediate consequence of this issue, as I mentioned, is my Doxygen documentation, which doesn't seem to warm to the idea of member specialization, at least the way I'm defining it at the moment. It will always present only the first definition it finds of a function/constant, and I really need to be able to present the specializations as well. If I go so far as to re-declare the entire class, i.e. in the header: /* template declaration */ template<class T> class X { public: static T v; static void f(T); }; /* template member definition */ template<class T> T X<T>::v = 0; template<class T> void X<T>::f(T arg) { v = arg; } /* declaration of specialized CLASS (with definitions in .cpp) */ template<> class X<float> { public: static float v; static void f(float); }; then it will display the different variations of X as different classes (which is fine by me), but I don't know how to get the same effect when specializing only a few select members of the class. I don't know if this is a mistake of mine, or a limitation of Doxygen - any ideas? Thanks much, Ziv

  • DTGridView losting content while scrolling

    - by Wim Haanstra
    I am using DTGridView from the DTKit by Daniel Tull. I implemented it in a very simple ViewController and the test I am doing is to place a button in the last row of the grid, which should add another row to the grid (and therefor moving the button to a row beneath it). The problem is, when I click the button a couple of times and then start scrolling, the grid seems to lose its content. As I am not completly sure this is a bug in the grid, but more in my code, I hope you guys can help me out and track down the bug. First I have my header file, which is quite simple, because this is a test: #import <UIKit/UIKit.h> #import "DTGridView.h" @interface TestController : UIViewController <DTGridViewDelegate, DTGridViewDataSource> { DTGridView* thumbGrid; } @end I declare a DTGridView, which will be my grid, where I want to put content in. Now, my code file: #import "TestController.h" @implementation TestController int rows = 1; - (NSInteger)numberOfRowsInGridView:(DTGridView *)gridView { return rows; } - (NSInteger)numberOfColumnsInGridView:(DTGridView *)gridView forRowWithIndex:(NSInteger)index { if (index == rows - 1) return 1; else return 3; } - (CGFloat)gridView:(DTGridView *)gridView heightForRow:(NSInteger)rowIndex { return 57.0f; } - (CGFloat)gridView:(DTGridView *)gridView widthForCellAtRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { if (rowIndex == rows - 1) return 320.0f; else return 106.6f; } - (DTGridViewCell *)gridView:(DTGridView *)gridView viewForRow:(NSInteger)rowIndex column:(NSInteger)columnIndex { DTGridViewCell *view = [[gridView dequeueReusableCellWithIdentifier:@"thumbcell"] retain]; if (!view) view = [[DTGridViewCell alloc] initWithReuseIdentifier:@"thumbcell"]; if (rowIndex == rows - 1) { UIButton* btnLoadMoreItem = [[UIButton alloc] initWithFrame:CGRectMake(10, 0, 301, 57)]; [btnLoadMoreItem setTitle:[NSString stringWithFormat:@"Button %d", rowIndex] forState:UIControlStateNormal]; [btnLoadMoreItem.titleLabel setFont:[UIFont boldSystemFontOfSize:20]]; [btnLoadMoreItem setBackgroundImage:[[UIImage imageNamed:@"big-green-button.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; [btnLoadMoreItem addTarget:self action:@selector(selectLoadMoreItems:) forControlEvents:UIControlEventTouchUpInside]; [view addSubview:btnLoadMoreItem]; [btnLoadMoreItem release]; } else { UILabel* label = [[UILabel alloc] initWithFrame:CGRectMake(10,0,100,57)]; label.text = [NSString stringWithFormat:@"%d x %d", rowIndex, columnIndex]; [view addSubview:label]; [label release]; } return [view autorelease]; } - (void) selectLoadMoreItems:(id) sender { rows++; [thumbGrid setNeedsDisplay]; } - (void)viewDidLoad { [super viewDidLoad]; thumbGrid = [[DTGridView alloc] initWithFrame:CGRectMake(0,0, 320, 320)]; thumbGrid.dataSource = self; thumbGrid.gridDelegate = self; [self.view addSubview:thumbGrid]; } - (void)viewDidUnload { [super viewDidUnload]; } - (void)dealloc { [super dealloc]; } @end I implement all the methods for the DataSource, which seem to work. The grid is filled with as many rows as my int 'rows' ( +1 ) has. The last row does NOT contain 3 columns, but just one. That cell contains a button which (when pressed) adds 1 to the 'rows' integer. The problem starts, when it starts reusing cells (I am guessing) and content start disappearing. When I scroll back up, the UILabels I am putting in the cells are gone. Is there some bug, code error, mistake, dumb-ass-move I am missing here? Hope anyone can help.

  • wpftoolkit DataGridTemplateColumn Template binding

    - by Guillaume
    I want my datagrid columns to share a cell/celledit template. I have the solution do that (thanks to WPF DataGridTemplateColumn shared template?). Now what I would love to is improving the readability by avoiding all the node nesting. My current view looks like that: <wpftk:DataGrid ItemsSource="{Binding Tests}" AutoGenerateColumns="False"> <wpftk:DataGrid.Resources> <DataTemplate x:Key="CustomCellTemplate"> <TextBlock Text="{TemplateBinding Content}"/> </DataTemplate> <DataTemplate x:Key="CustomCellEditingTemplate"> <TextBox Text="{TemplateBinding Content}"></TextBox> </DataTemplate> </wpftk:DataGrid.Resources> <wpftk:DataGrid.Columns> <wpftk:DataGridTemplateColumn Header="Start Date"> <wpftk:DataGridTemplateColumn.CellTemplate> <DataTemplate> <ContentPresenter ContentTemplate="{StaticResource CustomCellTemplate}" Content="{Binding StartDate}"/> </DataTemplate> </wpftk:DataGridTemplateColumn.CellTemplate> <wpftk:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ContentPresenter ContentTemplate="{StaticResource CustomCellEditingTemplate}" Content="{Binding StartDate}"/> </DataTemplate> </wpftk:DataGridTemplateColumn.CellEditingTemplate> </wpftk:DataGridTemplateColumn> <!--and again the whole block above for each columns...--> </wpftk:DataGrid.Columns> </wpftk:DataGrid> What I would like to achieve is to bind the value at the DataGridTemplateColumn level and propagate it to the template level. Anyone know how to do that? What I tried to do is something like that: <wpftk:DataGrid ItemsSource="{Binding Tests}" AutoGenerateColumns="False"> <wpftk:DataGrid.Resources> <DataTemplate x:Key="CustomCellTemplate"> <TextBlock Text="{Binding}"/> </DataTemplate> <DataTemplate x:Key="CustomCellEditingTemplate"> <TextBox Text="{Binding}"></TextBox> </DataTemplate> </wpftk:DataGrid.Resources> <wpftk:DataGrid.Columns> <wpftk:DataGridTemplateColumn Header="Start Date" Binding="{Binding StartDate}" CellTemplate="{StaticResource CustomCellTemplate}" CellEditingTemplate="{StaticResource CustomCellEditingTemplate}"/> <wpftk:DataGridTemplateColumn Header="End Date" Binding="{Binding EndDate}" CellTemplate="{StaticResource CustomCellTemplate}" CellEditingTemplate="{StaticResource CustomCellEditingTemplate}"/> </wpftk:DataGrid.Columns> </wpftk:DataGrid> Obviously the binding porperty is not a valid property of the DataGridTemplateColumn but maybe by playing with the datacontext and some relative source could do the trick but frankly I can't find a way to implement that. Not sure if what I want is possible and i'm willing to accept a "no way you can do that" as an answer NOTE: The TextBlock/TextBox in the template is just for test (the real template is much more complex) DataGridTextColumn will not do the trick Thanks in advance

  • Clear float issue

    - by Jason
    I have a page with the standard navigation bar on the left and the content area taking up the rest of the horizontal area to its side. For modern browsers I am using table-row and table-cell values for the display attribute. However, for IE7 I included a conditional stylesheet that tries to float the nav bar. This works fine except when the content area itself has floated elements and I try to use clear. My goal is to displayed the clear element right after the content area floats but instead it gets shoved down below the nav area. The following demo code shows this issue. My goal is to get the table to display right below the "leftThing" and "rightThing" but instead there is a large gap between them and the table. <html> <head> <title>Float Test</title> <style type="text/css"> #body { background: #cecece; } #sidebar { background: #ababab; float: left; width: 200px; } #content { background: #efefef; margin-left: 215px; } #leftThing { background: #456789; float: left; width: 100px; } #rightThing { background: #654321; float: right; width: 100px; } table { clear: both; } </style> </head> <body> <div id="body"> <div id="sidebar"> <ul> <li>One</li> <li>Two</li> <li>Three</li> </ul> </div> <div id="content"> <div style="position: realtive;"> <div id="leftThing"> ABCDEF </div> <div id="rightThing"> WXYZ </div> <table> <thead> <th>One</th> <th>Two</th> </thead> <tr> <td>Jason</td> <td>45</td> </tr> <tr> <td>Mary</td> <td>41</td> </tr> </table> <p>Exerci ullamcorper consequat duis ipsum ut nostrud zzril, feugait feugiat duis dolor feugiat commodo, accumsan, duis illum eum molestie luptatum nisl iusto.

  • inserting new relationship data in core-data

    - by michael
    My app will allow users to create a personalised list of events from a large list of events. I have a table view which simply displays these events, tapping on one of them takes the user to the event details view, which has a button "add to my events". In this detailed view I own the original event object, retrieved via an NSFetchedResultsController and passed to the detailed view (via a table cell, the same as the core data recipes sample). I have no trouble retrieving/displaying information from this "event". I am then trying to add it to the list of MyEvents represented by a one to many (inverse) relationship: This code: NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; [myEvents addEventObject:event];//ERROR And this code (suggested below): //would this add to or overwrite the "list" i am attempting to maintain NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSMutableSet *myEvent = [myEvents mutableSetValueForKey:@"event"]; [myEvent addObject:event]; //ERROR Bot produce (at the line indicated by //ERROR): *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance Seems I may have missed something fundamental. I cant glean any more information through the use of debugging tools, with my knowledge of them. 1) Is this a valid way to compile and store an editable list like this? 2) Is there a better way? 3) What could possibly be the deallocated instance in error? -- I have now modified the Event entity to have a to-many relationship called "myEvents" which referrers to itself. I can add Events to this fine, and logging the object shows the correct memory addresses appearing for the relationship after a [event addMyEventObject:event];. The same failure happens right after this however. I am still at a loss to understand what is going wrong. This is the backtrace #0 0x01f753a7 in ___forwarding___ () #1 0x01f516c2 in __forwarding_prep_0___ () #2 0x01c5aa8f in -[NSFetchedResultsController(PrivateMethods) _preprocessUpdatedObjects:insertsInfo:deletesInfo:updatesInfo:sectionsWithDeletes:newSectionNames:treatAsRefreshes:] () #3 0x01c5d63b in -[NSFetchedResultsController(PrivateMethods) _managedObjectContextDidChange:] () #4 0x0002e63a in _nsnote_callback () #5 0x01f40005 in _CFXNotificationPostNotification () #6 0x0002bef0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #7 0x01bbe17d in -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] () #8 0x01c1d763 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] () #9 0x01ba25ea in -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] () #10 0x01bdfb3a in -[NSManagedObjectContext processPendingChanges] () #11 0x01bd0957 in _performRunLoopAction () #12 0x01f4d252 in __CFRunLoopDoObservers () #13 0x01f4c65f in CFRunLoopRunSpecific () #14 0x01f4bc48 in CFRunLoopRunInMode () #15 0x0273878d in GSEventRunModal () #16 0x02738852 in GSEventRun () #17 0x002ba003 in UIApplicationMain () solution I managed to get to the bottom of this. I was fetching the event in question using a NSFetchedResultsController with a NSPredicate which I was releasing after I had the results. Retrieving values from the entities returned was no problem, but when I tried to update any of them it gave the error above. It should not have been released. oustanding part of my question What is a good way to create this sub list from a list of existing items in terms of a core data model. I don't believe its any of the ways I tried here. I need to show/edit it in another table view. Perhaps there is a better way than a boolean property on each event entity? The relationship idea above doesn't seem to work here (even though I can now create it). Cheers.

  • Geolocation through Android's GPS Provider on a website?

    - by Corey Ogburn
    I'm trying to get the geolocation of the mobile device in a regular website, not a webview of an application or anything native like that. I'm getting a location, but it's highly inaccurate, the accuracy comes back as 3230 or some other outrageous number. I'm assuming that's in meters, either way it's not nearly accurate enough. By comparison, the same webpage on a laptop gets an accuracy of 30-40. My first thought was that it was using the Network Provider instead of the GPS Provider, telling me where I am based on tower location and reach. A little research later I found enableHighAccuracy and set it true in the options that I pass. After including that, I still notice no difference. Here's the test page's HTML/javascript: <html> <head> <script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script> <script type="text/javascript"> function OnLoad() { $("#Status").text("Init"); if (navigator.geolocation) { $("#Status").text("Supports Geolocation"); navigator.geolocation.getCurrentPosition(HandleLocation, LocationError, { enableHighAccuracy: true }); $("#Status").text("Sent position request..."); } else { $("#Status").text("Doesn't support geolocation"); } } function HandleLocation(position) { $("#Status").text("Received response:"); $("#Position").text("(" + position.coords.latitude + ", " + position.coords.longitude + ") accuracy: " + position.coords.accuracy); var loc = new Microsoft.Maps.Location(position.coords.latitude, position.coords.longitude); GetMap(loc); } function LocationError(error) { switch(error.code) { case error.PERMISSION_DENIED: alert("Location not provided"); break; case error.POSITION_UNAVAILABLE: alert("Current location not available"); break; case error.TIMEOUT: alert("Timeout"); break; default: alert("unknown error"); break; } } function GetMap(loc) { var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), {credentials: "Aj59meaCR1e7rNgkfQy7j08Pd3mzfP1r04hGesGmLe2a3ZwZ3iGecwPX2SNPWq5a", center: loc, mapTypeId: Microsoft.Maps.MapTypeId.road, zoom: 15}); } </script> </head> <body onload="javascript:OnLoad()"> <div id="Status"></div> <div id="Position"></div><br/> <div id='mapDiv' style="position:relative; width:600px; height:400px;"></div> </body> </html> I'm testing this on a rooted MyTouch 3G running Cyanogen 6.1 stable, Android 2.2 and GPS is enabled. In case rooting was a problem, I have also had various friends and coworkers try the webpage on their non-rooted 2.0+ Android devices. Each phone had various effects on the accuracy, but none were better than 1000, I attribute this to the different carriers. I have not (but eventually will) tested with iPhone or other location-aware cell phones.
