• MS SQL Return 1 Row Per Boat

  - by Tyler

  Basically, what I want to do is join 4 tables together and return 1 row for each boat. Table Layouts [Boats] id, date, section, raft [Photos] id, boatid, pthurl, purl [River_Company] id, sort, company, company_short [River_Section] id, section Its very simple as far as structure, however, I've having the time of my life trying to get it to return only 1 row. No boat will ever be on the same day, the only thing that's messing this up is the photo table. If you know a better way for it to return the record table for all the boats boats and only 1 photo from the photo table, please, please post it!!

• django return file over HttpResonse - file is not served correctly

  - by Tom Tom

  I want to return some files in a HttpResponse and I'm using the following function. The file that is returned always has a filesize of 1kb and I do not know why. I can open the file, but it seems that it is not served correctly. Thus I wanted to know how one can return files with django/python over a HttpResponse. @login_required def serve_upload_files(request, file_url): import os.path import mimetypes mimetypes.init() try: file_path = settings.UPLOAD_LOCATION + '/' + file_url fsock = open(file_path,"r") #fsock = open(file_path,"r").read() file_name = os.path.basename(file_path) mime_type_guess = mimetypes.guess_type(file_name) try: if mime_type_guess is not None: response = HttpResponse(mimetype=mime_type_guess[0]) response['Content-Disposition'] = 'attachment; filename=' + file_name response.write(fsock) finally: fsock.close() except IOError: response = HttpResponseNotFound() return response

• Objective-C: How to create a method that will return a UInt8 array from an int

  - by Adam

  I need to create an Objective-C method that converts an int into a byte array. In this instance, I can't use NSArray as a return type, it must be an UInt8 array. I've written a simple method to do this, but it has errors during compile and tells me that I have incompatible return types. Here is the code snippet. Any ideas? - (UInt8[])ConvertToBytes:(int) i { UInt8 *retVal[4]; retVal[0] = i >> 24; retVal[1] = i >> 16; retVal[2] = i >> 8; retVal[3] = i >> 0; return retVal; }

• Can nusoap return array of string ?

  - by Tim

  Hi all, I would like to return an array of string in my web services I've tryed : <?php require_once('nusoap/nusoap.php'); $server = new soap_server(); $server->configureWSDL('NewsService', 'urn:NewsService'); $server->register('GetAllNews', array(), array('return' => 'xsd:string[]'), 'urn:NewsService', 'urn:NewsService#GetAllNews', 'rpc', 'literal', '' ); // Define the method as a PHP function function GetAllNews() { $stack = array("orange", "banana"); array_push($stack, "apple", "raspberry"); return $stack; } but it doesn't work. What is the correct syntax for that ? Thanks in advance for any help

• Extending DOMDocument and DOMNode: problem with return object

  - by Glauber Rocha

  I'm trying to extend the DOMDocument class so as to make XPath selections easier. I wrote this piece of code: class myDOMDocument extends DOMDocument { function selectNodes($xpath){ $oxpath = new DOMXPath($this); return $oxpath->query($xpath); } function selectSingleNode($xpath){ return $this->selectNodes($xpath)->item(0); } } These methods return a DOMNodeList and a DOMNode object, respectively. What I'd like to do now is to implement similar methods to the DOMNode objects. But obviously if I write a class (myDOMNode) that extends DOMNode, I won't be able to use these two extra methods on the nodes returned by myDOMDocument because they're DOMNode (and not myDOMNode) objects. I'm rather a beginner in object programming, I've tried various ideas but they all lead to a dead-end. Any hints? Thanks a lot in advance.

• return value from ajax request to another function

  - by stormdrain

  I'm trying to return a value from (transport) to the calling function, but can't seem to get it to work: function createXMLHttpRequest( w ) { var urly = '/users/notes/' + w; var options = { method:'get' , onSuccess: function( transport ) { x = transport.responseText; return x; } , onFailure: function( transport ) { var response = transport.responseText; alert( "FAILED "+ response ); } }; new Ajax.Request( urly, options ); alert( x ); } var ai = $( 'addItem' ); ai.onclick = function() { // -1 indicates new addnote( -1, null ); } x always alerts undefined. Unless I assign x to the Ajax.Request e.g. x=new Ajax.Request(urly,options). It then will alert [Object object]. How can I return the value of transport.responseText to the onclick function?

• How to return variable datatypes from a method

  - by Praesagus

  I have a method whose callers require different datatypes. I could repeat the requisite conversions a dozen times by putting them in each of the callers, but it seems much more efficient to do it once in the called method. public String myMethod(String myArg) { return DoSomething(myArg); } public Int32 myMethod(String myArg) { return Convert.ToInt32(DoSomething(myArg)); } private String DoSomething(key) { return SomeList[key]; } If I have multiple methods that pull data from SomeList and have to utilize different data types then in each I have to do a type conversion. Examples might be session variables or query or form requests or any other number of things. In VB I could say Function myMethod(myArg as String) as Variant myMethod=DoSomething(myArg) End Function Sorry if the original post was not very clear. I hope this makes more sense. Thanks

• How to return a code value into a variable

  - by Georges Sabbagh

  I have the below case in my report: Receivable: RunningValue(Fields!Receivable.Value,SUM,Nothing) Production: code.SumLookup(LookupSet(Fields!Currency_Type.Value, Fields!Currency_Type1.Value,Fields!Gross_Premium_Amount.Value, "DataSet2")) Rec/Prod: Receivable / Production. Public Function SumLookup(ByVal items As Object()) As Decimal If items Is Nothing Then Return Nothing End If Dim suma As Decimal = New Decimal() Dim ct as Integer = New Integer() suma = 0 ct = 0 For Each item As Object In items suma += Convert.ToDecimal(item) ct += 1 Next If (ct = 0) Then return 0 else return suma End Function The problem is for Rec/Prod, if prod = 0 i receive error. Ive tried to put the below condition: IIF(code.SumLookup(LookupSet(Fields!Currency_Type.Value, Fields!Currency_Type1.Value,Fields!Gross_Premium_Amount.Value, "DataSet2"))=0,0,RunningValue(Fields!Receivable.Value,SUM,Nothing)/(code.SumLookup(LookupSet(Fields!Currency_Type.Value, Fields!Currency_Type1.Value,Fields!Gross_Premium_Amount.Value, "DataSet2")))) but since in the false condition i am recalling code.SumLookup in order to get the value in regetting 0 for production and consiquently i get error for Rec/Prod. how can i call code.sumlookup on time only and save its value into a variable so i dont need to call it everytime i need to check the value. or if there any other solution please advise.

• How to return an image in an HTTP response with CherryPy

  - by colinmarc

  I have code which generates a Cairo ImageSurface, and I expose it like so: def preview(...): surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, width, height) ... cherrypy.response.headers['Content-Type'] = "image/png" return surface.get_data() preview.exposed = True This doesn't work (browsers report that the image has errors). I've tested that surface.write_to_png('test.png') works, but I'm not sure what to dump the data into to return it. I'm guessing some file-like object? According to the pycairo documentation, get_data() returns a buffer. I've also now tried: tempf = os.tmpfile() surface.write_to_png(tempf) return tempf Also, is it better to create and hold this image in memory (like I'm trying to do) or write it to disk as a temp file and serve it from there? I only need the image once, then it can be discarded.

• Java Math.cos() Method Does Not Return 0 When Expected

  - by dimo414

  Using Java on a Windows 7 PC (not sure if that matters) and calling Math.cos() on values that should return 0 (like pi/2) instead returns small values, but small values that, unless I'm misunderstanding, are much greater than 1 ulp off from zero. Math.cos(Math.PI/2) = 6.123233995736766E-17 Math.ulp(Math.cos(Math.PI/2)) = 1.232595164407831E-32 Is this in fact within 1 ulp and I'm simply confused? And would this be an acceptable wrapper method to resolve this minor inaccuracy? public static double cos(double a){ double temp = Math.abs(a % Math.PI); if(temp == Math.PI/2) return 0; return Math.cos(a); }

• how subsonic SP should return a value

  - by android.sm

  Hi all, I'm very much new to SubSonic and need a little guidance. Here, I want to know how my SP should return a value. Currently, when I execute it I simply pass an Int and it returns me a string value. Here is code: SubSonic SP: public static StoredProcedure GetQuote(int? CategoryId) { StoredProcedure sp = new StoredProcedure("GetQuote", DataService.GetInstance("Quotes Provider"), "dbo"); sp.Command.AddParameter("@CategoryId", CategoryId, DbType.Int32, 0, 10); return sp; } My Code: public bool GetQuote(int category, out string quote) { bool val = false; quote = ""; try { StoredProcedure sp = SPs.GetQuote(category); if (sp != null) { sp.Execute(); val = true; } } catch (Exception err) { throw err; } return val; } Thanks all

• Ruby Methods: how to return an usage string when insufficient arguments are given

  - by Shyam

  Hi, After I have created a serious bunch of classes (with initialize methods), I am loading these into IRb to test each of them. I do so by creating simple instances and calling their methods to learn their behavior. However sometimes I don't remember exactly what order I was supposed to give the arguments when I call the .new method on the class. It requires me to look back at the code. However, I think it should be easy enough to return a usage message, instead of seeing: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

• How to return all aspnet_compiler errors (not just those in first directory)

  - by Dan Atkinson

  Hi there! Is there a way to get the aspnet_compiler to go through all views and return all errors, rather than just the errors in the current view directory? For example, lets say I have a project that has a bunch of folders... Views Folder1 Folder2 Folder3 Folder4 Two of them (Folder2 and Folder3) have errors. aspnet_compiler will run, and only return the errors it comes across in Folder2. It won't return those in Folder3 at the same time. Once I fix the errors in Folder2 and run it again, it'll then pick up the ones in the Folder3. I fix those. And then have to run the tool again, and again until it's all fixed. This is getting annoying!! For reference, here's the command I use: C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler -v / -p "C:\path\to\project" Thanks in advance!

• g++ How to get warning on ignoring function return value

  - by ArunSaha

  lint produces some warning like: foo.c XXX Warning 534: Ignoring return value of function bar() From the lint manual 534 Ignoring return value of function 'Symbol' (compare with Location) A function that returns a value is called just for side effects as, for example, in a statement by itself or the left-hand side of a comma operator. Try: (void) function(); to call a function and ignore its return value. See also the fvr, fvo and fdr flags in §5.5 "Flag Options". I want to get this warning, if there exists any, during compilation. Is there any option in gcc/g++ to achieve this? I had turned on -Wall but that apparently did not detect this.

• Should I make OR operator to return const reference or just reference

  class error_code { public: error_code() : hi(0), lo(0) {} error_code(__int64 lo) : hi(0), lo(lo) {} error_code(__int64 hi, __int64 lo) : hi(hi), lo(lo) {} error_code& operator|=(const error_code &e) { this->hi |= e.hi; this->lo |= e.lo; return *this; } __int64 hi; __int64 lo; }; error_code operator|(const error_code& e0, const error_code& e1) { return error_code(e0.hi | e1.hi, e0.lo | e1.lo); } int main() { error_code e0(1); error_code e1(2); e0 |= e1; } I was wondering, whether I should make operator|= to return a const error_code& or error_code& ?

• return first non repeating character in a string

  - by Amm Sokun

  I had to solve this question in which given a string, i had to return the first non repeating character present in the string. I solved it using hashtable and wrote a method which takes a constant reference to the string and returns the first non repeating character. However, when there is no non repeating character present in the string, i return -1 and in the main program i check as follows char c = firstNonRepeating( word ); if (static_cast<int> (c) == -1) cout<<"no non repeating character present\n"; else cout<<c<<endl; is that the correct way to return -1 when required character is not present?

  How can I make a function which returns an array?

• Returning a ReadOnlyCollection from a method with an IList return type

  - by devoured elysium

  Here I have the following bit of code: private IList<IState> _states = new List<IState>(); private ReadOnlyCollection<IState> _statesViewer; public IList<IState> States { get { return _statesViewer; } } Generally it is preferable to return interfaces than the concrete classes themselves, but in this case, shouldn't I set as the return type of the States property a ReadOnlyCollection? Any user of my library will think it is possible to anything you can do with an IList if I set it as so, and that means adding elements. That is not true and I'm definitely breaking the contract exposing it as an IList. Am I right with this view or there is something else I am missing here?

• LINQ to sql return group by results from method

  - by petebob796

  How do I create a method to return the results of a group by in LINQ to sql such as the one below: internal SomeTypeIDontKnow GetDivisionsList(string year) { var divisions = from p in db.cm_SDPs where p.acad_period == year group p by new { p.Division } into g select new { g.Key.Division }; return divisions; } I can't seem to define a correct return type. I think it is because it's an anonymous type but haven't got my head around it yet. Do I need to convert it to a list or something? The results would just be used for filling a combo box.

• Different return value of an overridden class

I did that and the compiler didn't complain... could someone please explain? class MyBaseClass { int value; public: virtual int getValue() = 0; }; class MyClass : public MyBaseClass { double value; public: virtual double getValue(); // here!!! return is double, not int }; double MyClass::getValue() { return this->value; } The compiler totally accepted something similar (MSVC und MinGW)... could anyone please exaplain to what extent this is legal?

• Using Function return in global variable vb.net

  - by Cold Assassin

  Can't seem to figure out how to use a function return variable in global Dims example code: Public Class Main Dim Path As String = FixPath() Dim fixwrongtxt As String = Path & "tryme.txt" Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load FixPath() On_load() End Sub Private Function FixPath() As String Path = "C:\test" MsgBox(Path) //First Message Box' Return Path End Function Sub On_load() MsgBox(fixwrongtxt) //Second Message Box End Sub End Class when I run it all I get the first message box that contains "C:\test" and I click ok and on the second messagebox I get "custom.dll" with out the "C:\test" or "Path Return" What am I doing wrong? I know I can't use // in vb.net. I have also tried adding "FixPath()" under Sub On_load() but got same result. Also the reason I have to have these global is because I have around 30 Subs that refer to "Path" Variable... Thanks

• Extension method return using generics

  Is it possible to return a generic type using extension methods? For example, I have the following method: // Convenience method to obtain a field within a row (as a double type) public static double GetDouble(this DataRow row, string field) { if (row != null && row.Table.Columns.Contains(field)) { object value = row[field]; if (value != null && value != DBNull.Value) return Convert.ToDouble(value); } return 0; } This is currently used as follows: double value = row.GetDouble("tangible-equity"); but I would like to use the following code: double value = row.Get<double>("tangible-equity"); Is this possible and if so, what would the method look like?

• Foolproof way to check for nonzero (error) return code in windows batch file

  - by Pat

  Intro There's a lot of advice out there for dealing with return codes in batch files (using the ERROLEVEL mechanism), e.g. Get error code from within a batch file ERRORLEVEL inside IF Some of the advice is to do if errorlevel 1 goto somethingbad, while others recommend using the %ERRORLEVEL% variable and using ==, EQU, LSS, etc. There seem to be issues within IF statements and such, so then delayedexpansion is encouraged, but it seems to come with quirks of its own. Question What is a foolproof (i.e. robust, so it will work on nearly any system with nearly any return code) way to know if a bad (nonzero) code has been returned? My attempt For basic usage, the following seems to work ok to catch any nonzero return code: if not errorlevel 0 ( echo error level was nonzero )
