  • cellForRowAtIndexPath not called for all sections

    - by Wynn
    I have a UITableView that has five sections. Just as the title describes cellForRowAtIndexPath is only being called for the first four. All connections have been made concerning the datasource and delegate. Also, my numberOfSectionsInTableView clearly returns 5. Printing out the number of sections from within cellForRowAtIndexPath shows the correct number, thus confirming that cellForRowAtIndexPath is simply not being called for all sections. What on earth is going on? I looked pretty hard for an answer to this question but could't find one. If this has already been answered please forgive me and point me in the correct direction. My cellForRowAtIndexPath: - (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } switch (indexPath.section) { case 0: cell.textLabel.text = ticket.description; break; case 1: cell.textLabel.text = ticket.ticketStatus; break; case 2: cell.textLabel.text = ticket.priority; break; case 3: cell.textLabel.text = ticket.customerOfficePhone; break; case 4: { //This never ever gets executed Comment *comment = [ticket.comments objectAtIndex:indexPath.row]; cell.textLabel.text = comment.commentContent; break; } } return cell; } My numberOfSectionsInTableView: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 5; } My numberOfRowsInSection: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSInteger numberOfRows; if (section == 4) { numberOfRows = [ticket.comments count]; } else { numberOfRows = 1; } return numberOfRows; } Any suggestions are appreciated. Thanks in advance.

  • unclear use of @property in window app using core data

    - by Matt
    Looking through a Window based application ive used to experiment with as a way of getting my head around core data, ive noticed that the appdelegate has the following code myAppDelegate.h #import <UIKit/UIKit.h> #import <CoreData/CoreData.h> @interface iCaptureFreeAppDelegate : NSObject <UIApplicationDelegate> { NSManagedObjectModel *managedObjectModel; NSManagedObjectContext *managedObjectContext; NSPersistentStoreCoordinator *persistentStoreCoordinator; UIWindow *window; UITabBarController *tabBarController; } myAppDelegate.m #import "myAppDelegate.h" @interface iCaptureFreeAppDelegate (PrivateCoreDataStack) @property (nonatomic, retain, readonly) NSManagedObjectModel *managedObjectModel; @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; @property (nonatomic, retain, readonly) NSPersistentStoreCoordinator *persistentStoreCoordinator; @end @implementation iCaptureFreeAppDelegate @synthesize window, tabBarController; // code .... // - (NSManagedObjectContext *) managedObjectContext { } - (NSManagedObjectModel *)managedObjectModel { } - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { } // etc..... i want to understand a few things about what this project is doing why the properties in the category declaration? (if i delete the privateCoreDataStack category everything still works...) why the properties appear to be linked with the methods in the implementation ... managedObjectContext {} etc why the members in the .h file have the same name as the properties and the methods why code completion lets me use dot '.' to access the members but then fails on compilation say it cant find a getter thanks !

  • How to use a TFileStream to read 2D matrices into dynamic array?

    - by Robert Frank
    I need to read a large (2000x2000) matrix of binary data from a file into a dynamic array with Delphi 2010. I don't know the dimensions until run-time. I've never read raw data like this, and don't know IEEE so I'm posting this to see if I'm on track. I plan to use a TFileStream to read one row at a time. I need to be able to read as many of these formats as possible: 16-bit two's complement binary integer 32-bit two's complement binary integer 64-bit two's complement binary integer IEEE single precision floating-point For 32-bit two's complement, I'm thinking something like the code below. Changing to Int64 and Int16 should be straight forward. How can I read the IEEE? Am I on the right track? Any suggestions on this code, or how to elegantly extend it for all 4 data types above? Since my post-processing will be the same after reading this data, I guess I'll have to copy the matrix into a common format when done. I have no problem just having four procedures (one for each data type) like the one below, but perhaps there's an elegant way to use RTTI or buffers and then move()'s so that the same code works for all 4 datatypes? Thanks! type TRowData = array of Int32; procedure ReadMatrix; var Matrix: array of TRowData; NumberOfRows: Cardinal; NumberOfCols: Cardinal; CurRow: Integer; begin NumberOfRows := 20; // not known until run time NumberOfCols := 100; // not known until run time SetLength(Matrix, NumberOfRows); for CurRow := 0 to NumberOfRows do begin SetLength(Matrix[CurRow], NumberOfCols); FileStream.ReadBuffer(Matrix[CurRow], NumberOfCols * SizeOf(Int32)) ); end; end;

  • How do I place widgets above and below a listview?

    - by Jay Askren
    I have a list view and want to put stuff both above(on the y axis) and below(y axis) it including images, text views, and a row of buttons. Below is a simplified version of what I am creating. Unfortunately the list covers(i.e. above on the z axis) the header so the header text is not visible instead of being underneath (on the y axis) <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <TextView android:id="@+id/footer" android:text="footer" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentBottom="true" /> <ListView android:id="@+id/list_view" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_above="@id/footer" android:background="#ff9999ff"/> <TextView android:id="@+id/header" android:text="header" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentTop="true" android:layout_above="@id/list_view" android:baselineAlignBottom="false" /> </RelativeLayout> Here is the corresponding Activity class: public class SampleListActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list_activity); } }

  • avoiding code duplication in Rails 3 models

    - by Dustin Frazier
    I'm working on a Rails 3.1 application where there are a number of different enum-like models that are stored in the database. There is a lot of identical code in these models, as well as in the associated controllers and views. I've solved the code duplication for the controllers and views via a shared parent controller class and the new view/layout inheritance that's part of Rails 3. Now I'm trying to solve the code duplication in the models, and I'm stuck. An example of one of my enum models is as follows: class Format < ActiveRecord::Base has_and_belongs_to_many :videos attr_accessible :name validates :name, presence: true, length: { maximum: 20 } before_destroy :verify_no_linked_videos def verify_no_linked_videos unless self.videos.empty? self.errors[:base] << "Couldn't delete format with associated videos." raise ActiveRecord::RecordInvalid.new self end end end I have four or five other classes with nearly identical code (the association declaration being the only difference). I've tried creating a module with the shared code that they all include (which seems like the Ruby Way), but much of the duplicate code relies on ActiveRecord, so the methods I'm trying to use in the module (validate, attr_accessible, etc.) aren't available. I know about ActiveModel, but that doesn't get me all the way there. I've also tried creating a common, non-persistent parent class that subclasses ActiveRecord::Base, but all of the code I've seen to accomplish this assumes that you won't have subclasses of your non-persistent class that do persist. Any suggestions for how best to avoid duplicating these identical lines of code across many different enum models?

  • Point covering problem

    - by Sean
    I recently had this problem on a test: given a set of points m (all on the x-axis) and a set n of lines with endpoints [l, r] (again on the x-axis), find the minimum subset of n such that all points are covered by a line. Prove that your solution always finds the minimum subset. The algorithm I wrote for it was something to the effect of: (say lines are stored as arrays with the left endpoint in position 0 and the right in position 1) algorithm coverPoints(set[] m, set[][] n): chosenLines = [] while m is not empty: minX = min(m) bestLine = n[0] for i=1 to length of n: if n[i][0] <= m and n[i][1] > bestLine[1] then bestLine = n[i] add bestLine to chosenLines for i=0 to length of m: if m <= bestLine[1] then delete m[i] from m return chosenLines I'm just not sure if this always finds the minimum solution. It's a simple greedy algorithm so my gut tells me it won't, but one of my friends who is much better than me at this says that for this problem a greedy algorithm like this always finds the minimal solution. For proving mine always finds the minimal solution I did a very hand wavy proof by contradiction where I made an assumption that probably isn't true at all. I forget exactly what I did. If this isn't a minimal solution, is there a way to do it in less than something like O(n!) time? Thanks

    I need to display the contact pictures in a list view. In my custom_row_view.xml I have: <ImageView android:id="@+id/contact_image" android:layout_width="60dp" android:layout_height="50dp" /> and then in my activity i have: final SimpleAdapter adapter = new SimpleAdapter( this, list, R.layout.custom_row_view, new String[] {"avatar","telnumber","date","name","message","sent"}, new int[] {R.id.contact_image,R.id.text1,R.id.text2,R.id.text3,R.id.text4,R.id.isent} ); I have a hashmap HashMap temp2 = new HashMap(); where i put all the values of each line. ("list" is a list of Hashmap) But when I do: Cursor photo2 = managedQuery( Data.CONTENT_URI, new String[] {Photo.PHOTO}, // column for the blob Data._ID + "=?", // select row by id new String[]{photoid}, // filter by photoId null); Bitmap photoBitmap = null; if(photo2.moveToFirst()) { byte[] photoBlob = photo2.getBlob(photo2.getColumnIndex(Photo.PHOTO)); photoBitmap = BitmapFactory.decodeByteArray(photoBlob, 0, photoBlob.length); if (photoBitmap != null) temp2.put("avatar",photoBitmap); else temp2.put("avatar",R.drawable.unknowncontact); } photo2.close(); Nothing is displayed! "temp2.put("avatar",photoBitmap);" does not display anything but when I try to display something from the drawable folder it works!!! Please help me, i have been locked on this problem for several days! Thanks a lot!

  • Request header field x-user-session is not allowed by Access-Control-Allow-Headers

    - by Saurabh Bhandari
    I am trying to do a CORS call to a WCF service endpoint hosted on IIS7.5. I have configured custom headers in IIS. My configuration looks like below <customHeaders> <add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE,OPTIONS" /> <add name="Access-Control-Allow-Headers" value="x-user-session,origin, content-type, accept" /> <add name="Access-Control-Allow-Credentials" value="true" /> </customHeaders> When I do a POST request I get following error message "Request header field x-user-session is not allowed by Access-Control-Allow-Headers" If I remove my custom header from the call and run it, everything works fine. Also if I do a GET call with custom header then also API works correctly. $.ajax({ type:"POST", success: function(d) { console.log(d) }, timeout: 9000, url: "http://api.myserver.com/Services/v2/CreditCard.svc/update_cc_detail", data: JSON.stringify({"card_id": 1234,"expire_month":"11","expire_year":"2020","full_name":"Demo Account", "number":"4111111111111111","is_primary":true}), xhrFields: { withCredentials: true}, headers: { x-user-session': "B23680D0B8CB5AFED9F624271F1DFAE5052085755AEDDEFDA3834EF16115BCDDC6319BD79FDCCB1E199BB6CC4D0C6FBC9F30242A723BA9C0DFB8BCA3F31F4C7302B1A37EE0A20C42E8AFD45FAB85282FCB62C0B4EC62329BD8573FEBAEBC6E8269FFBF57C7D57E6EF880E396F266E7AD841797792619AD3F1C27A5AE" }, crossDomain: true, contentType: 'application/json' });

  • Counting in R data.table

    - by Simon Z.
    I have the following data.table set.seed(1) DT <- data.table(VAL = sample(c(1, 2, 3), 10, replace = TRUE)) VAL 1: 1 2: 2 3: 2 4: 3 5: 1 6: 3 7: 3 8: 2 9: 2 10: 1 Now I want to to perform two tasks: Count the occurrences of numbers in VAL. Count within all rows with the same value VAL (first, second, third occurrence) At the end I want the result VAL COUNT IDX 1: 1 3 1 2: 2 4 1 3: 2 4 2 4: 3 3 1 5: 1 3 2 6: 3 3 2 7: 3 3 3 8: 2 4 3 9: 2 4 4 10: 1 3 3 where COUNT defines task 1. and IDX task 2. I tried to work with which and length using .I: dt[, list(COUNT = length(VAL == VAL[.I]), IDX = which(which(VAL == VAL[.I]) == .I))] but this does not work as .I refers to a vector with the index, so I guess one must use .I[]. Though inside .I[] I again face the problem, that I do not have the row index and I do know (from reading data.table FAQ and following the posts here) that looping through rows should be avoided if possible. So, what's the data.table way?

  • HTML/CSS: Keep the same height between the backgrounds of a term-description pair in a table-like de

    - by peroyomas
    I want to format a definition list in HTML as if it were a table with th in a column and td in another, with a background that alternates per row (although a background for the dt and another for the dd also fits for the problem), so I have this CSS: dl { font-family: Verdana, Geneva, sans-serif; font-size: 0.6em; overflow: hidden; width: 200px;; } dl dt { font-weight: bold; float: left; clear: left; padding-right: 1%; width: 48%; } dl dt:nth-of-type(odd), dl dd:nth-of-type(odd) { background-color: #EEE; } dl dt:nth-of-type(even), dl dd:nth-of-type(even) { background-color: #DDD; } dl dd { float: left; width: 50%; padding-left: 1%; margin-left: 0; } Example HTML: <dl> <dt>Key 1</dt> <dd>Value 1</dd> <dt>Very very very long key 2 </dt> <dd>Value 2</dd> <dt>Key 3</dt> <dd>Value 3 with<br /> line breaks</dd> <dt>Key 4</dt> <dd>Value 4</dd> </dl> The problem is that, due to the eventual height dissimilarity, "holes" with no background appears in the list: Is there a way to fix that?

  • How to push further as a programmer?

    - by MaXX
    For the last, hmm, 6 months I've been reading into Programming in C, I got myself K&Rv2, BEEJ's socket guide, Expert C programming, Linux Systems Programming, the ISO/IEC 9899:1999 specification (real, and not draft). After receiving them from Amazon, I got Linux installed, and got to it. I'm done with K&R, about halfway through Expert C Programming, but still feel weak as a programmer, I'm sure it takes much more than 6 months of reading to become truly skilled, but my question is this: I've done all the exercises in K&Rv2 (in chapter 1) and some in other chapters, most of which are generally really boring. How do I lift my skills, and become truly great? I've invested money, time and a general lifestyle for something I truly desire, but I'm not sure how exactly to achieve it. Could someone explain to me, perhaps if I need to continuously code, what exactly I'm to code? I'm pretty sure, coding up hello world programs isn't going to teach me any more than I already know about anything. A friend of mine said "read" (with emphasis on read) a man page a day, but reading is all I do, I want to do, but I'm not sure what! I'm interested in security, but I'm not sure as a novice what to code that would be considered enough. Ah, I hope you don't delete this paste :) Thanks

  • std::vector elements initializing

    - by Chameleon
    std::vector<int> v1(1000); std::vector<std::vector<int>> v2(1000); std::vector<std::vector<int>::const_iterator> v3(1000); How elements of these 3 vectors initialized? About int, I test it and I saw that all elements become 0. Is this standard? I believed that primitives remain undefined. I create a vector with 300000000 elements, give non-zero values, delete it and recreate it, to avoid OS memory clear for data safety. Elements of recreated vector were 0 too. What about iterator? Is there a initial value (0) for default constructor or initial value remains undefined? When I check this, iterators point to 0, but this can be OS When I create a special object to track constructors, I saw that for first object, vector run the default constructor and for all others it run the copy constructor. Is this standard? Is there a way to completely avoid initialization of elements? Or I must create my own vector? (Oh my God, I always say NOT ANOTHER VECTOR IMPLEMENTATION) I ask because I use ultra huge sparse matrices with parallel processing, so I cannot use push_back() and of course I don't want useless initialization, when later I will change the value.

  • JQuery DataTables link item

    - by rogcg
    I'm trying to link the items from a specific column, but each one will be linked for a different id from the json string. Unfortunately I can't find a way to do this using the API (I know there is a lot of ways to do that without using the API ), but I'm looking for a way to link a item from a column (each one with a link for a specific id). So here is my code, I use getJSON to get the JSON from the server, and I load the data from this JSON to the table like this: $.getJSON("/method/from/server/", function(data) { var total = 0; $("#table_body").empty(); var oTable = $('#mytable').dataTable( { "sPaginationType" : "full_numbers", "aaSorting": [[ 0, "asc" ]] }); oTable.fnClearTable(); $.each(data, function(i, item) { oTable.fnAddData( [ item.contact_name, item.contact_email ] ); }); }); What I want to do, is for each row, link the contact_name to its id, which is also in the JSON, and can be accessed inside this $.each loop by using item.contact_id. Is there a way to do this using DataTables API, if yes, could you explain me and provide a good resource that will help me with this? Thanks.

  • HashMap Memory Leak because of Dynamic Array

    - by Jake M
    I am attempting to create my own HashMap to understand how they work. I am using an array of Linked Lists to store the values(strings) in my hashmap. I am creating the array like this: Node** list; Instead of this: Node* list[nSize]; This is so the array can be any size at runtime. But I think I am getting a memory leak because of how I am doing this. I dont know where the error is but when I run the following simple code the .exe crashes. Why is my application crashing and how can I fix it? Note: I am aware that using a vector would be much better than an array but this is just for learning and I want to challenge myself to create the hashmap using a 'Dynamic' Array. PS: is that the correct term(Dynamic Array) for the kind of array I am using? struct Node { // to implement }; class HashMap { public: HashMap(int dynSize) { *list = new Node[dynSize]; size = dynSize; for (int i=0; i<size; i++) list[i] = NULL; cout << "END\n"; } ~HashMap() { for (int i=0; i<size; i++) delete list[i]; } private: Node** list; // I could use a vector here but I am experimenting with a pointer to an array(pointer), also its more elegant int size; }; int main() { // When I run this application it crashes. Where is my memory leak? HashMap h(5); system("PAUSE"); return 0; }

  • Move SELECT to SQL Server side

    - by noober
    Hello all, I have an SQLCLR trigger. It contains a large and messy SELECT inside, with parts like: (CASE WHEN EXISTS(SELECT * FROM INSERTED I WHERE I.ID = R.ID) THEN '1' ELSE '0' END) AS IsUpdated -- Is selected row just added? as well as JOINs etc. I like to have the result as a single table with all included. Question 1. Can I move this SELECT to SQL Server side? If yes, how to do this? Saying "move", I mean to create a stored procedure or something else that can be executed before reading dataset in while cycle. The 2 following questions make sense only if answer is "yes". Why do I want to move SELECT? First off, I don't like mixing SQL with C# code. At second, I suppose that server-side queries run faster, since the server have more chances to cache them. Question 2. Am I right? Is it some sort of optimizing? Also, the SELECT contains constant strings, but they are localizable. For instance, WHERE R.Status = "Enabled" "Enabled" should be changed for French, German etc. So, I want to write 2 static methods -- OnCreate and OnDestroy -- then mark them as stored procedures. When registering/unregistering my assembly on server side, just call them respectively. In OnCreate format the SELECT string, replacing {0}, {1}... with required values from the assembly resources. Then I can localize resources only, not every script. Question 3. Is it good idea? Is there an existing attribute to mark methods to be executed by SQL Server automatically after (un)registartion an assembly? Regards,

  • In Silverlight, what structures, aside of the ListBox, can be used for binding?

    - by Aidenn
    I need to simply provide the content of a property to a custom User Control in Silverlight. My control is something like this: <UserControl x:Class="SilverlightApplication.Header" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="300" d:DesignHeight="120"> <Grid x:Name="Header_Layout"> <StackPanel x:Name="hiHeaderContent" Width="Auto" Margin="73,8,8,8"> <TextBlock x:Name="User:" Text="{Binding name}" /> </StackPanel> </Grid> I try to use this User Control from another control where I try to pass the parameter "name" to the previous UserControl ("Header"). I don't need to create a "ListBox" as I will only have 1 header, so I try to avoid doing: <ListBox x:Name="HeaderListBox" Grid.Row="0"> <ListBox.ItemTemplate> <DataTemplate> <SilverlightApplication:Header/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> in order to send the "User" account using: HeaderListBox.ItemsSource = name; Is there any other structure I can use instead of the ListBox to pass the parameter just once? It won't be a list, it's just a header... Thank you!

  • Iphone: XML image problem

    - by avanadra
    Hi! I have a question about parsing XML and putting it into a table. I parsed the following elements from a RSS feed : title, dc:creator and enclosure url (= an image). The parsing is working, i can see everything showing up in the console. But when i try to load everything into the tablecell, everything shows up except for the image. So i figured that the problem must be in the CellForRowatIndexPath method in the RootViewController.m ( or in the TableCell.m) What am i doing wrong? Please help! Ive been struggling for days with this and just cant seem to figure it out! Heres the CellForRowatIndexPath: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; WerkTableCell *cell = (WerkTableCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"WerkCell" owner:self options:nil]; cell =self.werkCell; } // Configure the cell. NSMutableArray *cont= [xmlcont items];// is niet in tablevb v.

  • how to emulate thread local storage at user space in C++ ?

    - by vprajan
    I am working on a mobile platform over Nucleus RTOS. It uses Nucleus Threading system but it doesn't have support for explicit thread local storage i.e, TlsAlloc, TlsSetValue, TlsGetValue, TlsFree APIs. The platform doesn't have user space pthreads as well. I found that __thread storage modifier is present in most of the C++ compilers. But i don't know how to make it work for my kind of usage. How does __thread keyword can be mapped with explicit thread local storage? I read many articles but nothing is so clear for giving me the following basic information will __thread variable different for each thread ? How to write to that and read from it ? does each thread has exactly one copy of the variable ? following is the pthread based implementation: pthread_key_t m_key; struct Data : Noncopyable { Data(T* value, void* owner) : value(value), owner(owner) {} int* value; }; inline ThreadSpecific() { int error = pthread_key_create(&m_key, destroy); if (error) CRASH(); } inline ~ThreadSpecific() { pthread_key_delete(m_key); // Does not invoke destructor functions. } inline T* get() { Data* data = static_cast<Data*>(pthread_getspecific(m_key)); return data ? data->value : 0; } inline void set(T* ptr) { ASSERT(!get()); pthread_setspecific(m_key, new Data(ptr, this)); } How to make the above code use __thread way to set & get specific value ? where/when does the create & delete happen? If this is not possible, how to write custom pthread_setspecific, pthread_getspecific kind of APIs. I tried using a C++ global map and index it uniquely for each thread and retrieved data from it. But it didn't work well.

N (see in above table) Root Node 5 Node 6 Node 7 Node 8 Node 9 The only way i can think of is to open a cursor, loop through each row and perform string split, just fetch the first 5 nodes and then insert into a temp table. Pls. suggest. Thanks

  • 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.

  • Reduce file size for charts pasted from excel into word

    - by Steve Clanton
    I have been creating reports by copying some charts and data from an excel document into a word document. I am pasting into a content control, so i use ChartObject.CopyPicture in excel and ContentControl.Range.Paste in word. This is done in a loop: Set ws = ThisWorkbook.Worksheets("Charts") With ws For Each cc In wordDocument.ContentControls If cc.Range.InlineShapes.Count > 0 Then scaleHeight = cc.Range.InlineShapes(1).scaleHeight scaleWidth = cc.Range.InlineShapes(1).scaleWidth cc.Range.InlineShapes(1).Delete .ChartObjects(cc.Tag).CopyPicture Appearance:=xlScreen, Format:=xlPicture cc.Range.Paste cc.Range.InlineShapes(1).scaleHeight = scaleHeight cc.Range.InlineShapes(1).scaleWidth = scaleWidth ElseIf ... Next cc End With Creating these reports using Office 2007 yielded files that were around 6MB, but creating them (using the same worksheet and document) in Office 2010 yields a file that is around 10 times as large. After unzipping the docx, I found that the extra size comes from emf files that correspond to charts that are pasted in using VBA. Where they range from 360 to 900 KB before, they are 5-18 MB. And the graphics are not visibly better. I am able to CopyPicture with the format xlBitmap, and while that is somewhat smaller, it is larger than the emf generated by Office 2007 and noticeably poorer quality. Are there any other options for reducing the file size? Ideally, I would like to produce a file with the same resolution for the charts as I did using Office 2007. Is there any way that uses VBA only (without modifying the charts in the spreadsheet)?

  • A generic error has occurred in GDI+

    - by sysigy
    I know this has been asked a million times but I think I need to make it a million and one. I am getting "A generic error has occurred in GDI+" when trying to save a new bitmap. I have completely stripped down to the most basic lines of code and I still get the error with the following method: public class HomeController : Controller { public ActionResult Index() { return this.View(); } public void CreatePicture() { try { // THIS WORKS System.IO.File.Copy("C:\\copyTest.bmp", "C:\\test folder\\copyTest2.bmp"); // THIS WORKS System.IO.File.Delete("C:\\test folder\\deleteTest.bmp"); using (Bitmap newBitmap = new Bitmap(120, 120)) { // THIS FAILS newBitmap.Save("C:\\test folder\\test.bmp", ImageFormat.Bmp); } } catch (Exception ex) { throw ex; } } } The code is called from an html link on a blank page within an MVC 3.0 website using anonymous login. View: @Html.ActionLink("Create Picture", "CreatePicture", "Home", new { }) I have checked the folder permissions of "test folder" and have given full access to the following: ASPNET NETWORK SERVICE IUSR I still get the error... what have I missed / done wrong ?

  • Java Graphics not displaying on successive function calls, why?

    - by primehunter326
    Hi, I'm making a visualization for a BST implementation (I posted another question about it the other day). I've created a GUI which displays the viewing area and buttons. I've added code to the BST implementation to recursively traverse the tree, the function takes in coordinates along with the Graphics object which are initially passed in by the main GUI class. My idea was that I'd just have this function re-draw the tree after every update (add, delete, etc...), drawing a rectangle over everything first to "refresh" the viewing area. This also means I could alter the BST implementation (i.e by adding a balance operation) and it wouldn't affect the visualization. The issue I'm having is that the draw function only works the first time it is called, after that it doesn't display anything. I guess I don't fully understand how the Graphics object works since it doesn't behave the way I'd expect it to when getting passed/called from different functions. I know the getGraphics function has something to do with it. Relevant code: private void draw(){ Graphics g = vPanel.getGraphics(); tree.drawTree(g,ORIGIN,ORIGIN); } vPanel is what I'm drawing on private void drawTree(Graphics g, BinaryNode<AnyType> n, int x, int y){ if( n != null ){ drawTree(g, n.left, x-10,y+10 ); if(n.selected){ g.setColor(Color.blue); } else{ g.setColor(Color.gray); } g.fillOval(x,y,20,20); g.setColor(Color.black); g.drawString(n.element.toString(),x,y); drawTree(g,n.right, x+10,y+10); } } It is passed the root node when it is called by the public function. Do I have to have: Graphics g = vPanel.getGraphics(); ...within the drawTree function? This doesn't make sense!! Thanks for your help.
