  • Google Reader API with Objective-C - Problem getting token

    - by JustinXXVII
    I am able to successfully get the SID (SessionID) for my Google Reader account. In order to obtain the feed and do other operations inside Google Reader, you have to obtain an authorization token. I'm having trouble doing this. Can someone shed some light? //Create a cookie to append to the GET request NSDictionary *cookieDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"SID",@"NSHTTPCookieName",self.sessionID,@"NSHTTPCookieValue",@".google.com",@"NSHTTPCookieDomain",@"/",@"NSHTTPCookiePath",@"NSHTTPCookieExpires",@"160000000000",nil]; NSHTTPCookie *authCookie = [NSHTTPCookie cookieWithProperties:cookieDictionary]; //The URL to obtain the Token from NSURL *tokenURL = [NSURL URLWithString:@"http://www.google.com/reader/api/0/token"]; NSMutableURLRequest *tokenRequest = [NSMutableURLRequest requestWithURL:tokenURL]; //Not sure if this is right: add cookie to array, extract the headers from the cookie inside the array...? [tokenRequest setAllHTTPHeaderFields:[NSHTTPCookie requestHeaderFieldsWithCookies:[NSArray arrayWithObjects:authCookie,nil]]]; //This gives me an Error 403 Forbidden in the didReceiveResponse of the delegate [NSURLConnection connectionWithRequest:tokenRequest delegate:self]; I get a 403 Forbidden error as the response from Google. I'm probably not doing it right. I set the dictionary values according to the documentation for NSHTTPCookie.

  • Certain transformations in Open Inventor(Coin3D)

    - by Marc
    Hi, I am quite new to Open Inventor(Coin3D) and have the following problem: I have a SoSelection holding a root node(also SoSeparator). And the root node holds a number of SoSeparator nodes. Each of these SoSeparator nodes holds a SoTransform node and a SoCube node. When I select one cube node I want all other cubes within a certain distance to the selected cube to arrange in a circle arround the selected cube. (Moreover all of the cubes should be on a plane than) An additional information: My cubes are always oriented in the camera direction with (cubeTransform_-rotation.connectFrom(&camera_-orientation) Assuming the selected cube is the center of the circle, how do I translate the other cubes in a circle on a plane(perpendicular to the vector between the selected cube and the camera)? Especially how do I find coordinates on the plain on which the circle should be which have a certain distance from the Axis (from center cube to camera). What I already did is to search for the for all cubes within a certain distance as soon as one cube is selected. As a result I already have the required separators (which are holding the according SoTransforms and SoCubes) in a SoPathList. Now I want to arrange the cubes by modifing the according SoTransform-translation values. Regards Mark

  • How to implement Excel Solver functionality in C#?

    - by Vic
    Hi, I have an application in C#, I need to do some optimization calculations, like Excel Solver Add-in does, one option is certainly to write my own solver implementation, but I'm kind of short of time, so I'm looking into libraries that already exist that can help me with this. I've been trying the Microsoft Solver Foundation, which seems pretty neat and cool, the problem is that it doesn't seem to work with the kind of calculations that I need to do. At the end of this question I'm adding the information about the calculations I need to perform and optimize. So basically my question is if any of you know of any other library that I can use for this purpose, or any tutorial that can help to do my own solver, or any idea that gives me a lead to solve this issue. Thanks. Additional Info: This is the data I need to calculate: I have 7 variables, lets call them var1, var2,...,var7 The constraints for these variables are: All of them need to be 0 <= varn <= 0.5 (where n is the number of the variable) The sum of all the variables should be equal to 1 The objective is to maximize the target formula, which in Excel looks like this: (MMULT(TRANSPOSE(L26:L32),M14:M20)) / (SQRT(MMULT(MMULT(TRANSPOSE(L26:L32),M4:S10),L26:L32))) The range that you see in this formula, L26:L32, is actually the range with the variables from above, var1, var2,..., varn. M14:M20 and M4:S10 are ranges with data that I get from different sources, there are more likely decimal values. As I said before, I was using Microsoft Solver Foundation, I modeled pretty much everything with it, I created functions that handle the operations of the target formula, but when I tried to solve the model it always fail, I think it is because of the complexity of the operations. In any case, I just wanted to show these data so you can have an idea about the kind of calculations that I need to implement.

  • When does it makes sense to use a map?

    - by kiwicptn
    I am trying to round up cases when it makes sense to use a map (set of key-value entries). So far I have five categories (see below). Assuming more exist, what are they? Please limit each answer to one unique category, put up an example, and vote up the fascinating ones. Property values (like a bean) age -> 30 sex -> male loc -> calgary Histograms peter -> 1 john -> 7 paul -> 5 Presence, with O(1) performance peter -> 1 john -> 1 paul -> 1 Functions peter -> treatPeter() john -> dealWithJohn() paul -> managePaul() Conversion peter -> pierre john -> jean paul -> paul

  • Problem with NSUserDefaults and deallocated Instance

    - by Peter A
    Hi, I'm having a problem with NSUserDefaults. I've followed the steps in the books as closely as I can for my app, but still get the same problem. I am getting a *** -[NSUserDefaults integerForKey:]: message sent to deallocated instance 0x3b375a0 error when I try and load in the settings. Here is the code that I have, it is in the App Delegate class. - (void)applicationDidFinishLaunching:(UIApplication *)application { recordingController = [[RecordingTableViewController alloc] initWithStyle:UITableViewStylePlain]; [recordingController retain]; // Add the tab bar controller's current view as a subview of the window [window addSubview:tabBarController.view]; [self loadSettings]; } -(void)loadSettings { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSNumber loop = [defaults objectForKey:@"loop_preference"]; NSNumber play = [defaults objectForKey:@"play_me_preference"]; NSNumber volume = [defaults objectForKey:@"volume_preference"]; } As you can see I am not trying to do anything with the values yet, but I get the error on the line reading in the loop preference. I also get it if I try and read an NSString. Any suggestions would be greatly appreciated. Thanks Peter

  • Help with SOAP request using PHP

    - by mptre
    I'm having a SOAP related problem in PHP. I'm trying to create arbitrary SOAP request using Nusoap_client class. The complete request including headers should look like the example below. Ofcourse the placeholders (string) should be replaced with actual values. POST /services/RecipeCouponAPI11.asmx HTTP/1.1 Host: example.com Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://www.example.com/services/GetCouponAll" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <RCAuthenticator xmlns="http://www.example.com/services/"> <UserName>string</UserName> <Password>string</Password> </RCAuthenticator> </soap:Header> <soap:Body> <GetCouponAll xmlns="http://www.example.com/services/"> <campaignCode>string</campaignCode> </GetCouponAll> </soap:Body> </soap:Envelope> I tried the following code with no luck. Seems like the request isn't formated correctly. Any ideas on how to get his working? <?php $client = new Nusoap_client('http://www.example.com/services/RecipeCouponAPI11.asmx'); $headers = new SoapHeader( 'http://www.example.com/services/', 'RCAuthenticator', (object)array( 'UserName' => 'username', 'Password' => 'password' ), false ); $client->setHeaders(array($headers)); $response = $client->call( 'GetCouponAll', array('campaignCode' => 'campaigncode'), null, 'http://www.example.com/services/GetCouponAll' ); ?> Thanks in advantage!

  • Deserializing a FileStream on Client using WCF

    - by Grandpappy
    I'm very new to WCF, so I apologize in advance if I misstate something. This is using .NET 4.0 RC1. Using WCF, I am trying to deserialize a response from the server. The base response has a Stream as its only MessageBodyMember. public abstract class StreamedResponse { [MessageBodyMember] public Stream Stream { get; set; } public StreamedResponse() { this.Stream = Stream.Null; } } The derived versions of this class are actually what's serialized, but they don't have a MessageBodyMember attribute (they have other base types such as int, string, etc listed as MessageHeader values). [MessageContract] public class ChildResponse : StreamedResponse { [DataMember] [MessageHeader] public Guid ID { get; set; } [DataMember] [MessageHeader] public string FileName { get; set; } [DataMember] [MessageHeader] public long FileSize { get; set; } public ChildResponse() : base() { } } The Stream is always a FileStream, in my specific case (but may not always be). At first, WCF said FileStream was not a known type, so I added it to the list of known types and now it serializes. It also appears, at first glance, to deserialize it on the client's side (it's the FileStream type). The problem is that it doesn't seem to be usable. All the CanRead, CanWrite, etc are false, and the Length, Position, etc properties throw exceptions when being used. Same with ReadByte(). What am I missing that would keep me from getting a valid FileStream?

  • Maintain one to one mapping between objects

    - by Rohan West
    Hi there, i have the following two classes that provide a one to one mapping between each other. How do i handle null values, when i run the second test i get a stackoverflow exception. How can i stop this recursive cycle? Thanks [TestMethod] public void SetY() { var x = new X(); var y = new Y(); x.Y = y; Assert.AreSame(x.Y, y); Assert.AreSame(y.X, x); } [TestMethod] public void SetYToNull() { var x = new X(); var y = new Y(); x.Y = y; y.X = null; Assert.IsNull(x.Y); Assert.IsNull(y.X); } public class X { private Y _y; public Y Y { get { return _y; } set { if(_y != value) { if(_y != null) { _y.X = null; } _y = value; if(_y != null) { _y.X = this; } } } } } public class Y { private X _x; public X X { get { return _x; } set { if (_x != value) { if (_x != null) { _x.Y = null; } _x = value; if (_x != null) { _x.Y = this; } } } } }

  • How to serialize a protected property in wcf

    - by Denis Rosca
    Hello everyone, I have to classes (Person and Address) that i need to send via wcf, the classes look like this: public class PersoanaFizica :IExtensibleDataObject { [DataMember] private Guid _id; [DataMember(Name = "Id")] protected virtual Guid Id { get { return _id; } set { _id = value; } } private ExtensionDataObject _extensionData; public virtual ExtensionDataObject ExtensionData { get { return _extensionData; } set { _extensionData = value; } } private string _firstName; [Searchable(PropertyName="FirstName")] [DataMember] public virtual string FirstName { get { return this._firstName; } set { this._firstName = value; } } private string _lastName; [Searchable(PropertyName="LastName")] [DataMember] public virtual string LastName { get { return this._lastName; } set { this. _lastName = value; } } private Address _address; [Searchable(PropertyName="Address")] [DataMember] public virtual Address Address { get { return this._address; } set { this._address = value; } } } public class Address : IExtensibleDataObject { [DataMember] private Guid _id; [DataMember] public virtual Guid Id { get { return _id; } set { _id = value; } } private ExtensionDataObject _extensionData; public virtual ExtensionDataObject ExtensionData { get { return _extensionData; } set { _extensionData = value; } } private string _country; [Searchable(PropertyName="Country")] [DataMember] public virtual string Country { get { return this._country; } set { this._country = value; } } // and some other properties related to the address } The problem is that when i try to send them via wcf, the client recieves the Id properties set to 00000-0000-00000-00000 or smth like this. Any idea why this is happening? And how to serialize the proper values? Thanks,Denis.

  • Find and Replace RegEx with wildcard search and addition of value

    - by fraXis
    The below code is from my other questions that I have asked here on SO. Everyone has been so helpful and I almost have a grasp with regards to RegEx but I ran into another hurdle. This is what I basically need to do in a nutshell. I need to take this line that is in a text file that I load into my content variable: X17.8Y-1.Z0.1G0H1E1 I need to do a wildcard search for the X value, Y value, Z value, and H value. When I am done, I need this written back to my text file (I know how to create the text file so that is not the problem). X17.8Y-1.G54G0T2 G43Z0.1H1M08 I have code that the kind users here have given me, except I need to create the T value at the end of the first line, and use the value from the H and increment it by 1 for the T value. For example: X17.8Y-1.Z0.1G0H5E1 would translate as: X17.8Y-1.G54G0T6 G43Z0.1H5M08 The T value is 6 because the H value is 5. I have code that does everything (does two RegEx functions and separates the line of code into two new lines and adds some new G values). But I don't know how to add the T value back into the first line and increment it by 1 of the H value. Here is my code: StreamReader reader = new StreamReader(fDialog.FileName.ToString()); string content = reader.ReadToEnd(); reader.Close(); content = Regex.Replace(content, @"X[-\d.]+Y[-\d.]+", "$0G54G0"); content = Regex.Replace(content, @"(Z(?:\d*\.)?\d+)[^H]*G0(H(?:\d*\.)?\d+)\w*", "\nG43$1$2M08"); //This must be created on a new line This code works great at taking: X17.8Y-1.Z0.1G0H5E1 and turning it into: X17.8Y-1.G54G0 G43Z0.1H5M08 but I need it turned into this: X17.8Y-1.G54G0T6 G43Z0.1H5M08 (notice the T value is added to the first line, which is the H value +1 (T = H + 1). Can someone please modify my RegEx statement so I can do this automatically? I tried to combine my two RegEx statements into one line but I failed miserably.

  • How to bind data from a view of type List<List<MyViewModelClass>>?

    - by Robert Koritnik
    I have a strong type view of type List<List<MyViewModelClass>> The outer list will always have two lists of List<MyViewModelClass>. For each of the two outer lists I want to display a group of checkboxes. Each set can have an arbitrary number of choices. My view model class looks similar to this: public class MyViewModelClass { public Area Area { get; set; } public bool IsGeneric { get; set; } public string Code { get; set; } public bool IsChecked { get; set; } } So the final view will look something like: Please select those that apply: First set of choices: x Option 1 x Option 2 x Option 3 etc. Second set of choices: x Second Option 1 x Second Option 2 x Second Option 3 x Second Option 4 etc. Checkboxes should display MyViewModelClass.Area.Name, and their value should be related to MyViewModelClass.Area.Id. Checked state is of course related to MyViewModel.IsChecked. Question I wonder how should I use Html.CheckBox() or Html.CheckBoxFor() helper to display my checkboxes? I have to get these values back to the server on a postback of course. If it makes things simpler, I could make a separate view model type like: public class Options { public List<MyViewModelClass> General { get; set; } public List<MyViewModelClass> Others { get; set; } }

  • Passing PaginatedList to ActionResult MVC C#

    - by Darcy
    Hi all, I wanted to create a simple paginated search for my project. I'm having trouble with my 'advanced search' page, where I have several textbox inputs that the user would fill with the appropriate data (basically just several filters). My view is strongly-typed with the paginatedList class similar to the NerdDinner tutorial. In my controller, I wanted to pass the PaginatedList as a parameter since my view contains several bits of info from the PaginatedList model. The PaginatedList was null (as parameter), then I changed added the route; the object itself is not null anymore, but the values are. View: <%= Html.TextBox("Manufacturers", Model.Manufacturers) %> <%= Html.TextBox("OtherFilters", Model.FilterX) %> //...etc etc Controller: public ActionResult AdvancedSearchResults(PaginatedList<MyModel> paginatedList) { //... } Any ideas? Am I even going about this correctly? Should I create a ViewModel that encapsulates the paginatedList info as well as the additional info I need instead?

  • django: grouping in an order_by query?

    - by AP257
    Hi all, I want to allocate rankings to users, based on a points field. Easy enough you'd think with an order_by query. But how do I deal with the situation where two users have the same number of points and need to share the same ranking? Should I use annotate to find users with the same number of points? My current code, and a pseudocode description of what I'd like to do, are below. top_users = User.objects.filter(problem_user=False).order_by('-points_total') # Wrong - in pseudocode, this should be # Get the highest points_total, find all the users with that points_total, # if there is more than one user, set status to 'Joint first prize', # otherwise set status to 'First prize' top_users[0].status = "First prize" if (top_users[1]): top_users[1].status = "Second prize" if (top_users[2]): top_users[2].status = "Third prize" if (top_users[3]): top_users[3:].status = "Highly commended" The code above doesn't deal with the situation where two users have the same number of points and need to share second prize. I guess I need to create a query that looks for unique values of points_total, and does some kind of nested ranking? It also doesn't cope with the fact that sometimes there are fewer than 4 users - does anyone know how I can do (in pseudocode) 'if top_users[1] is not null...' in Python?

  • jquery disable/remove option on select?

    - by SoulieBaby
    Hi all, I have two select lists, I would like jquery to either remove or disable a select option, depending on what is selected from the first select list: <select name="booking" id="booking"> <option value="3">Group Bookings</option> <option value="2" selected="selected">Port Phillip Bay Snapper Charters</option> <option value="6">Portland Tuna Fishing</option> <option value="1">Sport Fishing</option> </select> Here's the second list (which will only ever have two values): <select name="charterType" id="charterType"> <option value="1">Individual Booking</option> <option value="2">Group Booking</option> </select> If Group Bookings or Port Phillip Bay Snapper Charters are selected, I need only "Group Booking" to be displayed. (To basically hide "Individual Booking") but I can't seem to get it to work.. If someone could help me that'd be great!! :) I've also tried using a switch, but that doesnt work either.. /* select list */ switch (jQuery('#booking :selected').text()) { case 'Sport Fishing': alert('AA'); break; case 'Port Phillip Bay Snapper Charters': jQuery("#charterType option[value=1]").remove(); alert('BB'); break; case 'Portland Tuna Fishing': alert('CC'); break; case 'Group Bookings': alert('DD'); break; }; It alerts, but doesn't do anything else..

  • What are the specific names for these OLE controls?

    - by Kris
    I have been working on making a block of code that would enable me to input values into a worksheet, as well as an MSgraph object. I have succeeded in this, but this has just presented me with a new set of problems: What are the control names for changing the visible size as well as the focus of a worksheet? What are the control names for changing/making background colours and borders? How do I create and define new worksheets and MSGraph objects inside the document? My example code so far: Option Explicit Dim objWord 'Word application object Dim objIShape 'Inline shapes object Dim objOLE 'OLE object Set objWord=CreateObject("Word.Application") objWord.Application.Documents.Open("C:\birdy.doc") objWord.Visible=True Set objIShape = objWord.ActiveDocument.InlineShapes Function count_filled_spaces(intOLENo, strRange) 'Activates the the inline shape by number(intOLENo) and defines it as the OLE object objIShape(intOLENo).OLEFormat.Activate Set objOLE = objIShape(intOLENo).OLEFormat.Object 'Detects the ClassType of the inline shape and uses a class specific counter to count which datafields have data Dim strClass, i, p, intSheetno intSheetno = 1 strClass = objIShape(intOLENo).OLEFormat.ClassType i = 0 If Left(strClass, 8) = "MSGraph." then For Each p In objOLE.Application.DataSheet.Range(strRange) If p <> "" Then i = i+1 End If Next ElseIf Left(strClass, 6) = "Excel." then For Each p In objOLE.Worksheets(intSheetno).Range(strRange) If p <> "" Then i = i+1 End If Next objOLE.Worksheets(intSheetno).Range("B" & i+1) = objOLE.Worksheets(intSheetno).Range("B" & i) End if count_filled_spaces = i End Function Dim strRange strRange = InputBox("Lol", "do eeet", "B1:B10") wscript.echo count_filled_spaces(2, strRange) 'objWord.Application.Documents.Save 'objWord.Application.Documents.Close 'objWord.Application.Quit WScript.Quit(0)

  • Force Oracle error on fetch

    - by Dan
    I am trying to debug a strange behavior in my application. In order to do so, I need to reproduce a scenario where an SQL SELECT query will throw an error, but only while actually fetching from the cursor, not while executing the query itself. Can this be done? Any error will do, but ORA-01722: invalid number seems like the obvious one to try. I created a table with the follwing: KEYCOL INTEGER PRIMARY KEY OTHERCOL VARCHAR2(100) I then created a few hundred rows with unique values for the primary key and the value l for the othercol. I then ran a SELECT * query, picked a row somewhere in the middle, and updated it to the string abcd. I ran the query SELECT KEYCOL, TO_NUMBER(OTHERCOL) FROM SOMETABLE hoping to get some rows of good data an then an error later. But I keep getting ORA-01722: invalid number on the execute step itself. I have gotten this behavior programmatically using ADO (with server-side cursor) and JDBC, as well as from PL/SQL Developer. How can I get the result I'm looking for? thanks Edit - meant to add, when using ADO, I am only calling Command.Execute. I am not creating or opening a Recordset.

  • How to hide items under the options from one select box upon selection of an item in another select

    - by jl
    Hi, I am new to jQuery and would like to know how is it possible for me to hide an option in a selection box based on the selection of another selection box. I have 5 selection boxes, this is for the administrator to select the users of a limited criteria. The <options> are create dynamically from the results of a database query and php, and they all have the same <options>. e.g. this is an example of the selection boxes with their option values. userbox1 - Amy, Bosh, Cathy, Daniel, Ethan userbox2 - Amy, Bosh, Cathy, Daniel, Ethan userbox3 - Amy, Bosh, Cathy, Daniel, Ethan userbox4 - Amy, Bosh, Cathy, Daniel, Ethan userbox5 - Amy, Bosh, Cathy, Daniel, Ethan So if the administrator selects Cathy in userbox1, Cathy will be automatically be hidden from the selection on the rest of the userbox. And if the administrator changes his/her mind and reselect another user call Ethan. The userboxes should be able to show the availability of Cathy in the selection. I am not sure is hide/show the correct status to be used in such cases. May I know how is it possible to write the function as stated above? If I am missing some current references, kindly point me to it. Thanks in advance.

  • recursively implementing 'minimum number of coins' in python

    - by user5198
    This problem is same as asked in here. Given a list of coins, their values (c1, c2, c3, ... cj, ...), and the total sum i. Find the minimum number of coins the sum of which is i (we can use as many coins of one type as we want), or report that it's not possible to select coins in such a way that they sum up to S. I"m just introduced to dynamic programming yesterday and I tried to make a code for it. # Optimal substructure: C[i] = 1 + min_j(C[i-cj]) cdict = {} def C(i, coins): if i <= 0: return 0 if i in cdict: return cdict[i] else: answer = 1 + min([C(i - cj, coins) for cj in coins]) cdict[i] = answer return answer Here, C[i] is the optimal solution for amount of money 'i'. And available coins are {c1, c2, ... , cj, ...} for the program, I've increased the recursion limit to avoid maximum recursion depth exceeded error. But, this program gives the right answer only someones and when a solution is not possible, it doesn't indicate that. What is wrong with my code and how to correct it?

  • Empty data problem - data layer or DAL?

    - by luckyluke
    I designing the new App now and giving the following question a lot of thought. I consume a lot of data from the warehouse, and the entities have a lot of dictionary based values (currency, country, tax-whatever data) - dimensions. I cannot be assured though that there won't be nulls. So I am thinking: create an empty value in each of teh dictionaries with special keyID - ie. -1 do the ETL (ssis) do the correct stuff and insert -1 where it needs to let the DAL know that -1 is special (Static const whatever thing) don't care in the code to check for nullness of dictionary entries because THEY will always have a value But maybe I should be thinking: import data AS IS let the DAL do the thinking using empty record Pattern still don't care in the code because business layer will have what it needs from DAL. I think is more of a approach thing but maybe i am missing something important here... What do You think? Am i clear? Please don't confuse it with empty record problem. I do use emptyCustomer think all the time and other defaults too.

  • Using stdint.h and ANSI printf?

    - by nn
    Hi, I'm writing a bignum library, and I want to use efficient data types to represent the digits. Particularly integer for the digit, and long (if strictly double the size of the integer) for intermediate representations when adding and multiplying. I will be using some C99 functionality, but trying to conform to ANSI C. Currently I have the following in my bignum library: #include <stdint.h> #if defined(__LP64__) || defined(__amd64) || defined(__x86_64) || defined(__amd64__) || defined(__amd64__) || defined(_LP64) typedef uint64_t u_w; typedef uint32_t u_hw; #define BIGNUM_DIGITS 2048 #define U_HW_BITS 16 #define U_W_BITS 32 #define U_HW_MAX UINT32_MAX #define U_HW_MIN UINT32_MIN #define U_W_MAX UINT64_MAX #define U_W_MIN UINT64_MIN #else typedef uint32_t u_w; typedef uint16_t u_hw; #define BIGNUM_DIGITS 4096 #define U_HW_BITS 16 #define U_W_BITS 32 #define U_HW_MAX UINT16_MAX #define U_HW_MIN UINT16_MIN #define U_W_MAX UINT32_MAX #define U_W_MIN UINT32_MIN #endif typedef struct bn { int sign; int n_digits; // #digits should exclude carry (digits = limbs) int carry; u_hw tab[BIGNUM_DIGITS]; } bn; As I haven't written a procedure to write the bignum in decimal, I have to analyze the intermediate array and printf the values of each digit. However I don't know which conversion specifier to use with printf. Preferably I would like to write to the terminal the digit encoded in hexadecimal. The underlying issue is, that I want two data types, one that is twice as long as the other, and further use them with printf using standard conversion specifiers. It would be ideal if int is 32bits and long is 64bits but I don't know how to guarantee this using a preprocessor, and when it comes time to use functions such as printf that solely rely on the standard types I no longer know what to use.

  • Dashcode code translation

    - by Alex Mcp
    Hi, a quick, probably easy question whose answer is probably "best practice" I'm following a tutorial for a custom-template mobile Safari webapp, and to change views around this code is used: function btnSave_ClickHandler(event) { var views = document.getElementById('stackLayout'); var front = document.getElementById('mainScreen'); if (views && views.object && front) { views.object.setCurrentView(front, true); } } My question is just about the if conditional statement. What is this triplet saying, and why do each of those things need to be verified before the view can be changed? Does views.object just test to see if the views variable responds to the object method? Why is this important? EDIT - This is/was the main point of this question, and it regards not Javascript as a language and how if loops work, but rather WHY these 3 things specifically need to be checked: Under what scenarios might views and front not exist? I don't typically write my code so redundantly. If the name of my MySQL table isn't changing, I'll just say UPDATE 'mytable' WHERE... instead of the much more verbose (and in my view, redundant) $mytable = "TheSQLTableName"; if ($mytable == an actual table && $mytable exists && entries can be updated){ UPDATE $mytable; } Whereas if the table's name (or in the JS example, the view's names) ARE NOT "hard coded" but are instead a user input or otherwise mutable, I might right my code as the DashCode example has it. So tell me, can these values "go wrong" anyhow? Thanks!

  • Mysql latin1 turkish data and delphi 2010 utf8

    - by sabri.arslan
    Hello, I have tables collating latin1_general_ci and have turkish character values. And i can use this data on delphi 7+zeos with no problem. but i want to upgrade my delphi to 2010 version but zeos too slow as i saw. so i want to use odbc+ado or dbexpress solution. dbexpress solution works fine , display my data as entered and write as entered table without any change to column charset. but dbexpress has problems as i saw. for example when i select * from table which has column types as varchar,decimal,int,tinyint,text give av errors on xp systems. vista and 7 does not give any error and work fine(not fully tested). ado solution(dbgo) works fine but its not show my data as entered.its want everything be utf. but i don't want to convert my data to utf before test everything. how can i see my data as entered and write client side utf and store latin1(as zeos or dbexpress do). i was tried many other options. eg. mysql side collation and charset parameters. sorry for my bad english. i hope someone understand me. thanks.

  • Changing Positions of the Chart When Creating Multiple Charts Automatically via Vbasic in Excel 2007

    - by McVey
    I am creating a new chart for each row of data in an Excel spreadsheet. I have the Vbasic working properly, but I want to change the position of the chart on the sheet that is added for each row. Below is my code, what do I need to do to change the position of the chart on the page automatically? Ideally, I would like it to be in the upper left hand corner of each sheet. Sub DrawCharts() Dim Ws As Worksheet Dim NewWs As Worksheet Dim cht As Chart Dim LastRow As Long Dim CurrRow As Long Set Ws = ThisWorkbook.Worksheets("Sheet1") LastRow = Ws.Range("A65536").End(xlUp).Row For CurrRow = 2 To LastRow Set NewWs = ThisWorkbook.Worksheets.Add NewWs.Name = Ws.Range("A" & CurrRow).Value Set cht = ThisWorkbook.Charts.Add With cht .ChartType = xl3DColumnClustered .SeriesCollection.NewSeries .SeriesCollection(1).Values = "=" & Ws.Name & "!R" & CurrRow & "C3:R" & CurrRow & "C8" .SeriesCollection(1).Name = "=" & Ws.Name & "!R" & CurrRow & "C2" .SeriesCollection(1).XValues = "Sheet1!R1C3:R1C8" .Axes(xlValue).MinimumScale = 0 .Axes(xlValue).MaximumScale = 1 .Axes(xlValue).MajorUnit = 0.2 .SetElement (msoElementDataLabelShow) .SetElement (msoElementLegendNone) .Location Where:=xlLocationAsObject, Name:=NewWs.Name End With Next CurrRow End Sub Any help is appreciated.
