• Use relative Path in Microsoft Surface application?

  - by Roflcoptr

  I convert my wave file into a mp3 file by the following code: internal bool convertToMp3() { string lameEXE = @"C:\Users\Roflcoptr\Documents\Visual Studio 2008\Projects\Prototype_Concept_2\Prototype_Concept_2\lame\lame.exe"; string lameArgs = "-V2"; string wavFile = fileName; string mp3File = fileName.Replace("wav", "mp3"); Process process = new Process(); process.StartInfo = new ProcessStartInfo(); process.StartInfo.FileName = lameEXE; process.StartInfo.Arguments = string.Format("{0} {1} {2}", lameArgs, wavFile, mp3File); process.Start(); process.WaitForExit(); int exitCode = process.ExitCode; if (exitCode == 0) { return true; } else { return false; } } This works, but now I'd like to not use the absolut path to the lame.exe but a relative path. I included a lame.exe in the folder /lame/ on the root of the project. How can I reference it?

• Application with both console and gui mode

  - by mridang

  Hi, I have a python console app. Like most python console apps it uses the OptionParser module to take arguments. I've now developed a GUI for my app using wxPython and i'd like to integrate the two. I'd like my app to be run both from the console and from the OS's UI. When it is invoked from the console it runs as a console app and when it is double clicked in the OS's UI, it runs as a GUI app. How could I do something like this? Could someone show me a a snippet of what the __main__ block should be like? Thanks a ton.

• what is wrong with this insert method in asp.net mvc?

  - by Pandiya Chendur

  My controller calls a repository class method on insert, [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create([Bind(Exclude = "Id")]FormCollection collection) { try { MaterialsObj materialsObj = new MaterialsObj(); materialsObj.Mat_Name = collection["Mat_Name"]; materialsObj.Mes_Id = Convert.ToInt64(collection["MeasurementType"]); materialsObj.Mes_Name = collection["Mat_Type"]; materialsObj.CreatedDate = System.DateTime.Now; materialsObj.CreatedBy = Convert.ToInt64(1); materialsObj.IsDeleted = Convert.ToInt64(1); consRepository.createMaterials(materialsObj); return RedirectToAction("Index"); } catch { return View(); } } and my repository class has this, public MaterialsObj createMaterials(MaterialsObj materialsObj) { db.Materials.InsertOnSubmit(materialsObj); return materialsObj; } But when i compile this i get The best overloaded method match for 'System.Data.Linq.Table<CrMVC.Models.Material>.InsertOnSubmit(CrMVC.Models.Material)' has some invalid arguments... cannot convert from 'CrMVC.BusinessObjects.MaterialsObj' to 'CrMVC.Models.Material'.. am i missing something?

• parse/collator for php

  - by dramatic

  I'm pretty much a newbie at php (at the "install an app and try to tweak it a bit" stage). Is there a tool anywhere which can take a script which is spread over many files and show you all the code which is processed (for a given set of arguments passed to the script) in a single output? For example, I want to make a call to zen cart from a script in a different language, which returns a category listing without any surrounding page. So I want to be able to trace what the actual process is to generate that then strip off all the unwanted bits to create a custom script.

• How do I get output into Java from a SELECT stored procedure in Oracle?

  - by Ventrue

  I'm using Java to connect to an Oracle 10 Database. I want to create a stored procedure (don't ask why) that takes no arguments and returns a lot of rows. Specifically, in Java I want to be able to get this data with something like: ResultSet rs = stmt.executeQuery("call getChildless"); where getChildless is the query: SELECT objectid FROM Object WHERE objectid NOT IN (SELECT parent FROM subparts); However, I just cannot for the life of me figure out how to get my output from the stored procedure. I've googled it and I get all this sample code that Oracle won't compile, presumably it's for a previous version. Refcursors seem to come up a lot, but I'm not sure if that's what I actually want, to use it with a ResultSet.

• An exception to avoid copy and paste code?

  - by Jian Lin

  There are many files in our project that would call a Facebook api. And the call is complicated, spanning usually 8 lines or more, just for the argument values. In this case, we can make it into a function, and place that function in a common_library.php, but doing so would just change the name of the function call from the Facebook API function to our name, and we still need to repeat the 8 lines of arguments. Each time, the call is very similar, but with slight variations to the argument values. In that case, would copy and paste be needed no matter what we do?

• GNU make variables in Makefile

  - by JTom

  Hi, I would like to create a Makefile which also creates a simple script for running the compiled application. I have something like the following: @touch $(SCRIPT) @echo LD_LIBRARY_PATH=$(LIB_DIR) $(APP_DIR)/$(APP) $1 $2 $3 $4 $5 $6 > $(SCRIPT) @chmod +x $(SCRIPT) @echo Script successfully created. And I want $1 $2 ... to appear in the script exactly like $1 $2 ... to represent scripts command-line arguments. I can't get it worked because Makefile is using $1 $2 as its own variables.. How can I accomplish that?

• Python list as *args?

  - by Cap

  I have two Python functions, both of which take variable arguments in their function definitions. To give a simple example: def func1(*args): for arg in args: print arg def func2(*args): return [2 * arg for arg in args] I'd like to compose them -- as in func1(func2(3, 4, 5)) -- but I don't want args in func1 to be ([6, 7, 8],), I want it to be (6, 7, 8), as if it was called as func1(6, 7, 8) rather than func1([6, 7, 8]). Normally, I would just use func1(*func2(3, 4, 5)) or have func1 check to see if args[0] was a list. Unfortunately, I can't use the first solution in this particular instance and to apply the second would require doing such a check in many places (there are a lot of functions in the role of func1). Does anybody have an idea how to do this? I imagine some sort of introspection could be used, but I could be wrong.

• Can I override a theme function with a .tpl file?

  - by Nick Lowman

  Hi everyone, How would I go around overriding a theme function with a .tpl file? I know how to override a .tpl file with a theme function but not the other way round. I can't seem to find anywhere that tells me so, so maybe it's not possible or not good practise. For example if there was a theme function defined in a module called super_results and registered with the theme registry, like the example below, how would I go around overriding it with super_results.tpl.php. 'super_results' => array( 'arguments' => array('title' => NULL, 'results' => NULL, 'votes' => NULL), ), function modulename_super_results($title, $results,$votes){ output HTML }

• C++ threaded class design from non-threaded class

  - by macs

  I'm working on a library doing audio encoding/decoding. The encoder shall be able to use multiple cores (i.e. multiple threads, using boost library), if available. What i have right now is a class that performs all encoding-relevant operations. The next step i want to take is to make that class threaded. So i'm wondering how to do this. I thought about writing a thread-class, creating n threads for n cores and then calling the encoder with the appropriate arguments. But maybe this is an overkill and there is no need for another class, so i'm going to make use of the "user interface" for thread-creation. I hope there are any suggestions.

• Powershell function that creates a array by input

  - by user2971548

  I'm quite new to Powershell and working on a little project with functions. What I'm trying to do is creating a function that takes 2 arguments. The first argument ($Item1) decides the size of the array, the second argument ($Item2) decides the value of the indexes. So if I write: $addToArray 10 5 I need the function to create a array with 10 indexes and the value 5 in each of them. The second argument would also have to take "text" as a value. This is my code so far. $testArray = @(); $indexSize = 0; function addToArray($Item1, $Item2) { while ($indexSize -ne $Item1) { $indexSize ++; } Write-host "###"; while ($Item2 -ne $indexSize) { $script:testArray += $Item2; $Item2 ++; } } Any help is appreciated. Kind regards Dennis Berntsson

• Inverse Factorial Function (Prolog)

  - by user2796815

  I have to write a Prolog program to computer the inverse of factorial function without using division. I was also given the note: "the inverse of a function is not necessarily a function". I have this is a normal factorial predicate.. fact(0,1). fact(N,F) :- N0, N1 is N-1, fact(N1,F1), F is N * F1. I've read on some other posts that you should be able to just switch around the arguments, but that doesn't seem to be the case with this version. Could anyone help me out with figuring out why?

• Is there any self-improving compiler around?

  - by JohnIdol

  I am not aware of any self-improving compiler, but then again I am not much of a compiler-guy. Is there ANY self-improving compiler out there? Please note that I am talking about a compiler that improves itself - not a compiler that improves the code it compiles. Any pointers appreciated! Side-note: in case you're wondering why I am asking have a look at this post. Even if I agree with most of the arguments I am not too sure about the following: We have programs that can improve their code without human input now — they’re called compilers. ... hence my question.

• Python ctypes argument errors

  - by Patrick Moriarty

  Hello. I wrote a test dll in C++ to make sure things work before I start using a more important dll that I need. Basically it takes two doubles and adds them, then returns the result. I've been playing around and with other test functions I've gotten returns to work, I just can't pass an argument due to errors. My code is: import ctypes import string nDLL = ctypes.WinDLL('test.dll') func = nDLL['haloshg_add'] func.restype = ctypes.c_double func.argtypes = (ctypes.c_double,ctypes.c_double) print(func(5.0,5.0)) It returns the error for the line that called "func": ValueError: Procedure probably called with too many arguments (8 bytes in excess) What am I doing wrong? Thanks.

• Calling a method with getattr in Python

  - by brain_damage

  How to call a method using getattr? I want to create a metaclass, which can call non-existing methods of some other class that start with the word 'oposite_'. The method should have the same number of arguments, but to return the opposite result. def oposite(func): return lambda s, *args, **kw: not oposite(s, *args, **kw) class Negate(type): def __getattr__(self, name): if name.startswith('oposite_'): return oposite(self.__getattr__(name[8:])) def __init__(self,*args,**kwargs): self.__getattr__ = Negate.__getattr__ class P(metaclass=Negate): def yep(self): return True But the problem is that self.__getattr__(sth) returns a NoneType object. >>> p = P() >>> p.oposite_yep() Traceback (most recent call last): File "<pyshell#115>", line 1, in <module> p.oposite_yep() TypeError: <lambda>() takes at least 1 positional argument (0 given) How to deal with this?

• VB.net WebBrowser and AJAX List Options

  - by Vinsick

  I'm writing a VB.net program for a website that uses the AJAX Lits options http://www.ajaxdaddy.com/demo-dhtml-autocomplete.html Whats more is that the website has used additional arguments in the function that i'm not exactly sure what they are calling, and there a trigger that executes an action that must be click, tabbing and returning fail. Any idea on how to automate this? This website has been a holy terror since it was unleashed on my company. I've tried this: Dim ObjArr(4) As Object ObjArr(0) = CObj("prac_select") ObjArr(1) = CObj("'getCountriesByLetters'") ObjArr(2) = CObj("1") ObjArr(3) = CObj("'prac_name'") ObjArr(4) = CObj("'practice'") WebBrowser1.Document.InvokeScript("ajax_showOptions", ObjArr)

• I'd like to know why a function executes fine when called from x but not when called from y

  When called from archive(), readcont(char *filename) executes fine! Called from runoptions() though, it fails to list the files "archived"! why is this? The program must run in terminal. Use -h as a parameter to view the usage. This program is written to "archive" text files into ".rldzip" files. readcont( char *x) should show the files archived in file (*x) a) Successful call Use the program to archive 3 text files: rldzip.exe a.txt b.txt c.txt FILEXY -a archive() will call readcont and it will work showing the files archived after the binary FILEXY will be created. b) Unsuccessful call After the file is created, use: rldzip.exe FILEXY.rldzip -v You can see that the function crashes! I'd like to know why is this happening! /* Sa se scrie un program care: a) arhiveaza fisiere b) dezarhiveaza fisierele athivate */ #include<stdio.h> #include<stdlib.h> #include<conio.h> #include<string.h> struct content{ char *text; char *flname; }*arc; FILE *f; void readcont(char *x){ FILE *p; if((p = fopen(x, "rb")) == NULL){ perror("Critical error: "); exit(EXIT_FAILURE); } content aux; int i; fread(&i, sizeof(int), 1, p); printf("\nFiles in %s \n\n", x); while(i-- >1 && fread(&aux, sizeof(struct content), 1, p) != 0) printf("%s \n", aux.flname); fclose(p); printf("\n\n"); } void archive(int argc, char **argv){ int i; char inttext[5000], textline[1000]; //Allocate dynamic memory for the content to be archived! arc = (content*)malloc(argc * sizeof(content)); for(i=1; i< argc; i++) { if((f = fopen(argv[i], "r")) == NULL){ printf("%s: ", argv[i]); perror(""); exit(EXIT_FAILURE); } while(!feof(f)){ fgets(textline, 5000, f); strcat(inttext, textline); } arc[i-1].text = (char*)malloc(strlen(inttext) + 1); strcpy(arc[i-1].text, inttext); arc[i-1].flname = (char*)malloc(strlen(argv[i]) + 1); strcpy(arc[i-1].flname, argv[i]); fclose(f); } char *filen; filen=(char*)malloc(strlen(argv[argc])+1+7); strcpy(filen, argv[argc]); strcat(filen, ".rldzip"); f = fopen(filen, "wb"); fwrite(&argc, sizeof(int), 1, f); fwrite(arc, sizeof(content), argc, f); fclose(f); printf("Success!

• Issue when I'm trying to draw gradient in swift

  - by bagusflyer

  I got an error when I was trying to draw gradient in Swift code: GradientView.swift:31:40: Could not find an overload for '__conversion' that accepts the supplied arguments Here is my code: let context : CGContextRef = UIGraphicsGetCurrentContext() let locations :CGFloat[] = [ 0.0, 0.25, 0.5, 0.75 ] let colors = [UIColor.redColor().CGColor,UIColor.greenColor().CGColor,UIColor.blueColor().CGColor, UIColor.yellowColor().CGColor] let colorspace : CGColorSpaceRef = CGColorSpaceCreateDeviceRGB() let gradient : CGGradientRef = CGGradientCreateWithColors(colorspace, colors, locations) //CGGradientCreateWithColors(colorspace,colors,locations) let startPoint : CGPoint = CGPointMake(0, 0) let endPoint : CGPoint = CGPointMake(500,500) CGContextDrawLinearGradient(context, gradient,startPoint, endPoint, 0); The problem is the CGGradientCreateWithColors takes CFArray not a normal Swift Array. I have no idea how to convert CFArray to Array and can't find anything in Apple's document. Any idea? Thanks

  suppose i have a dll with 2 functions.name of dll="dll1" f1(int a, int b, int c); f2(int a); my program would take the funtion name ,the dll name and a "list" of parameters as input. how would i call the appropriate function with its appropriate parameters. i.e, if input is dll1 f1 list(5,8,9) this would require me to call f1 with 3 parameters if input was dll1 f2 list(8) it would require me to call f2 with one parameter how would i call the function without knowing the number of parameters in advance. further clarification: how do I write code that will call any function with all its arguments by building the argument list dynamically using some other source of information

• combination of open source licenses

  - by Nicola Montecchio

  Hi I'm about to release some software as open source. It uses Lucene (Apache license) and jopt simple (MIT license). Are there any constraints on the license that I am going to apply to my own software? In particular, it is an adaptation of Lucene for performing content-based search on audio (so, many classes are inherited and in one case copied with a little modification). It only uses jopt simple for handling command line arguments (i.e. no modification at all, just "import" and "new OptionParser..."). Thanks for your help Nicola Montecchio

• Does to_json require parameters? what about within rails?

  - by Harry Wood

  Does to_json require parameters? what about within rails? I started getting the error "wrong number of arguments (0 for 1)" when doing myhash.to_json Unfortunately I'm not sure when this error started happening, but I guess it relates to some versions of either rails or the json gem. I suppose my code (in a rails controller) is using the ActiveSupport::JSON version of to_json, rather than the to_josn method supported by the json gem. ActiveSupport::JSON vs JSON In environment.rb I have RAILS_GEM_VERSION = '2.3.2' and also config.gem "json", :version=> '1.1.7' It's just a simple hash structure containing primitives which I want to convert in my controller, and it was working, but now I can't seem to run to_json without passing parameters.

• Poll: Require Semicolons and Forbid Tables?

  - by George Bailey

  There are a few very serious but opinionated and subjective arguments that I know of. Two of them are Whether or not to use semicolons in the event they are optional. There is a vote as here that also includes reasons Whether or not to use tables for non tabular data. There more information here Since the semicolon question arises often in JavaScript and the tables thing in HTML then there are probably many who run into both. I sort of expect a person who is strict with semicolons also to be strict about avoiding tables. I will post four CW answers here to vote on. Please vote what you think is right. If you want to talk about the reasons then please use Semicolons: Do you recommend using semicolons after every statement in JavaScript? Tables: Start your own question under the polls tag and follow the design of the semicolons question.
