• Need Help with wxPython & pyGame

  - by Xavier

  Hi Guys, I'm actually in need of your help and advice here on my assignment that I am working on. First of all, I was task to do a program that runs langton's ant simulation. For that, I've managed to get the source code (from snippets.dzone.com/posts/show/5143) and edited it accordingly to my requirements. This was done and ran in pygame module extension. In addition, my task requires a GUI to interface for users to run and navigate through the screens effectively with the langton's ant program running. I used wxPython with the help of an IDE called BOA constructor to create the frames, buttons, textboxes, etc. Basically, all the stuff needed in the interfaces. However, I've ran into some problems listed below: Found problem integrating pyGame with wxPython. On this note, I've research the internet for answers and tutorials where I found out from website: wiki.wxpython.org/IntegratingPyGame & aspn.activestate.com/ASPN/Mail/Message/wxpython-users/3178042. I understand from the sites that integrating pyGame with wxPython will be a difficult task where it has caused common problems like the inability to placing other controls into the frames as the pyGame application will cover the entire panel. I really hope that you can clarify my doubts on this and advise me on the path that I should take from here. Therefore, I ask the following questions: Is it feasible to integrate pyGame with wxPython? If it is not feasible to integrate pyGame with wxPython, what other alternatives do I have to create a GUI interface integrating pyGame into it. If so how do I go about? If it is possible to go about integrating pyGame with wxPython, how do I go about doing so? Really need you guys opinion on this.

• undefined references

  - by Brandon

  Hello, I'm trying to compile some fortran code and I'm running into some confusing linking errors. I have some code that I compile and place into a static library: >gfortran -c -I../../inc -o bdout.o bdout.F >ar rv libgeo.a bdout.o I then try to compile against that library with some simple test code and get the following: >gfortran -o mytest -L -lgeo mytest.F /tmp/cc4uvcsj.o: In function `MAIN__': mytest.F:(.text+0xb0): undefined reference to `ncwrite1_' collect2: ld returned 1 exit status It's not in the object naming because everything looks fine: >nm -u libgeo.a bdout.o: U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ I can check the original object file too: >nm -u bdout.o U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ The test code simply contains a single call to a function defined in bdout.o: program hello print *,"Hello World!" call ncwrite1( istat, f, ix2, ix3, ix4, ix5, ih ) end program hello I can't figure out what the problem is. Does anyone have any suggestions? Maybe even just a way to track the problem down? Cheers.

• Iterate through main function in C?

  - by Mohit Deshpande

  Here is my main function: int main(int argc, char **argv) { LoadFile(); Node *temp; char *key; switch (GetUserInput()) { case 1: temp = malloc(sizeof(Node)); printf("\nEnter the key of the new node: "); scanf("%s", temp->key); printf("\nEnter the value of the new node: "); scanf("%s", temp->value); AddNode(temp); free(temp); break; case 2: key = malloc(sizeof(char *)); printf("Enter the key of the node you want to delete: "); scanf("%s", key); DeleteNode(key); free(key); break; case 3: PrintAll(); break; case 4: SaveFile(); break; case 5: return 0; break; default: printf("\nWrong choice!\n"); break; } return 0; } The only problem with it is that after any case statement breaks, the program just exits out. I understand why, but I don't know how to fix it. I want the program to repeat itself each time even after the case statements. Would I just say: main(argc, argv); before every break statement?

• How is conversion of float/double to int handled in printf?

  - by Sandip

  Consider this program int main() { float f = 11.22; double d = 44.55; int i,j; i = f; //cast float to int j = d; //cast double to int printf("i = %d, j = %d, f = %d, d = %d", i,j,f,d); //This prints the following: // i = 11, j = 44, f = -536870912, d = 1076261027 return 0; } Can someone explain why the casting from double/float to int works correctly in the first case, and does not work when done in printf? This program was compiled on gcc-4.1.2 on 32-bit linux machine. EDIT: Zach's answer seems logical, i.e. use of format specifiers to figure out what to pop off the stack. However then consider this follow up question: int main() { char c = 'd'; // sizeof c is 1, however sizeof character literal // 'd' is equal to sizeof(int) in ANSI C printf("lit = %c, lit = %d , c = %c, c = %d", 'd', 'd', c, c); //this prints: lit = d, lit = 100 , c = d, c = 100 //how does printf here pop off the right number of bytes even when //the size represented by format specifiers doesn't actually match //the size of the passed arguments(char(1 byte) & char_literal(4 bytes)) return 0; } How does this work?

• Multiple, Simultaneous Factories and Protocols in Twisted: Same Service, Different Ports

  - by RichardCroasher

  Greetings, Forum. I'm working on a program in Python that uses Twisted to manage networking. The basis of this program is a TCP service that is to listen for connections on multiple ports. However, instead of using one Twisted factory to handle a protocol object for each port, I am trying to use a separate factory for each port. The reason for this is to force a separation among the groups of clients connecting to the different ports. Unfortunately, it appears that this architecture isn't quite working: clients that connect to one port appear to be available among all the factories (e.g., the protocol class used by each factory includes a 'self.factory.clients.append (self)' statement...instead of adding a given client to just the factory for a particular port, the client is added to all factories), and whenever I shutdown service on one port the listeners on all ports also stop. I've been working with Twisted for a short while, and fear I simply don't fully understand how its factory classes are managed. My question is: is it simply not possible to have multiple, simultaneous instances of the same factory and same protocol in use across different ports (without these instances stepping on each other's toes)?

• Unable to find reference to std library math function inside library

  - by Alex Marshall

  Hello, I've got several programs that use shared libraries. Those shared libraries in turn use various standard C libraries. ie Program A and Program B both use Shared Library S. Shared Library S uses std C math. I want to be able to statically link Shared Library S against the standard library, and then statically link Programs A and B against S so that I don't have to be dragging around the library files, because these programs are going to be running on an embedded system running BusyBox 0.61. However, when I try to statically link the programs against Shared Library S, I get an error message from GCC stating : ../lib/libgainscalecalc.a(gainscalecalc.): In function 'float2gs': [path to my C file].c:73: undefined reference to 'log' Can somebody please help me out ? The make commands I'm using are below : CFLAGS += -Wall -g -W INCFLAGS = -I$(CROSS_INCLUDE)/usr/include LIBFLAGS += -L$(CROSS_LIB)/usr/lib -lm gainscalecalc_static.o: gainscalecalc.c $(CC) $(CFLAGS) -c $< -I. $(INCFLAGS) -o $@ gainscalecalc_dynamic.o: gainscalecalc.c $(CC) $(CFLAGS) -fPIC -c $< -o $@ all: staticlib dynamiclib static_driver dynamic_driver clean: $(RM) *.o *.a *.so *~ driver core $(OBJDIR) static_driver: driver.c staticlib $(CC) $(CFLAGS) -static driver.c $(INCFLAGS) $(LIBFLAGS) -I. -L. -lgainscalecalc -o $@ dynamic_driver: driver.c dynamiclib $(CC) $(CFLAGS) driver.c -o $@ -L. -lgainscalecalc staticlib: gainscalecalc_static.o $(AR) $(ARFLAGS) libgainscalecalc.a gainscalecalc_static.o $(RANLIB) libgainscalecalc.a chmod 777 libgainscalecalc.a dynamiclib: gainscalecalc_dynamic.o $(CC) -shared -o libgainscalecalc.so gainscalecalc_dynamic.o chmod 777 libgainscalecalc.so Edit: Linking against the shared libraries compiles fine, I just haven't tested them out yet

• Splitting string on probable English word boundaries

  - by Sean

  I recently used Adobe Acrobat Pro's OCR feature to process a Japanese kanji dictionary. The overall quality of the output is generally quite a bit better than I'd hoped, but word boundaries in the English portions of the text have often been lost. For example, here's one line from my file: softening;weakening(ofthemarket)8 CHANGE [transform] oneselfINTO,takethe form of; disguise oneself I could go around and insert the missing word boundaries everywhere, but this would be adding to what is already a substantial task. I'm hoping that there might exist software which can analyze text like this, where some of the words run together, and split the text on probable word boundaries. Is there such a package? I'm using Emacs, so it'd be extra-sweet if the package in question were already an Emacs package or could be readily integrated into Emacs, so that I could simply put my cursor on a line like the above and repeatedly invoke some command that splits the line on word boundaries in decreasing order of probable correctness.

• Android-iPhone single codebase cross development

  - by Lorenzo

  Is there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android? The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C. What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS? Update: based on current answers, the best cross platform development tool for iOS and Android seems to be Titanium appcelerator. I suspect that this topic will evolve overtime, so feel free to contribute with new information and comments. Thank you!

• PostScript versus PDF as an output format

  - by Brecht Machiels

  I'm currently writing a typesetting application and I'm using PSG as the backend for producing postscript files. I'm now wondering whether that choice makes sense. It seems the ReportLab Toolkit offers all the features PSG offers, and more. ReportLab outputs PDF however. Advantages PDF offers: transparancy better support for character encodings (Unicode, for example) ability to embed TrueType and even OpenType fonts hyperlinks and bookmarks Is there any reason to use Postscript instead of directly outputting to PDF? While Postscript is a full programming language as opposed to PDF, as a basic output format for documents, that doesn't seem to offer any advantage. I assume a PDF can be readily converted to PostScript for printing? Some useful links: Wikipedia: PDF Adobe: PostScript vs. PDF

• how do i work bool!

  - by user350217

  HI! im a beginner and im really getting frustrated with this whole concept. i dont understand how to exactly use the bool function. i know what it is but i cantfigure out how to make it work in my program. Im trying to say that if my variable "selection" is any letter beween 'A' and 'I' then it is valid and can continue on to the next function which is called calcExchangeAmt(amtExchanged, selection). if it is false i want it to ask the user if they want to repeat the program and if they agree to repeat i want it to clear the screen and restart to the main function. please help edit my work! this is my bool function: bool isSelectionValid(char selection, char yesNo, double amtExchanged) { bool validData; validData = true; if((selection >= 'a' && selection <= 'i') || (selection >= 'A' && selection <= 'I')) { validData = calcExchangeAmt (amtExchanged, selection); } else(validData == false); { cout<<"Do you wish to continue? (Y for Yes / N for No)"; cin>>yesNo; } do { main(); } while ((yesNo =='y')||(yesNo == 'Y')); { system("cls"); } return 0; } this is the warning that im gettng: warning C4800: 'double' : forcing value to bool 'true' or 'false' (performance warning)

• Merging two templates in iText

  - by Shaggy Frog

  Let's say I have two PDF templates created with Adobe Acrobat, which are both single-page, 8.5x11 documents. The first template (A.pdf) has content for the top half of the page. The second template (B.pdf) has content for the bottom half of the page. (It just so happens the content in both templates does not "overlap" each other.) I would like to use iText to take these two templates and create a single, "merged" template from it (C.pdf) that is only a single page (with A.pdf's content on the top half and B.pdf's content on the bottom half). (I do not want to "merge" these two files into a 2-page document. I need the final product to be a single page.) I will be running iText in a servlet environment (Tomcat 6) but I don't think that makes a difference to the answer. Is this possible?

• How to parse a custom XML-style error code response from a website

  - by user1870127

  I'm developing a program that queries and prints out open data from the local transit authority, which is returned in the form of an XML response. Normally, when there are buses scheduled to run in the next few hours (and in other typical situations), the XML response generated by the page is handled correctly by the java.net.URLConnection.getInputStream() function, and I am able to print the individual results afterwards. The problem is when the buses are NOT running, or when some other problem with my queries develops after it is sent to the transit authority's web server. When the authority developed their service, they came up with their own unique error response codes, which are also sent as XMLs. For example, one of these error messages might look like this: <Error xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <Code>3005</Code> <Message>Sorry, no stop estimates found for given values.</Message> </Error> (This code and similar is all that I receive from the transit authority in such situations.) However, it appears that URLConnection.getInputStream() and some of its siblings are unable to interpret this custom code as a "valid" response that I can handle and print out as an error message. Instead, they give me a more generic HTTP/1.1 404 Not Found error. This problem cascades into my program which then prints out a java.io.FileNotFoundException error pointing to the offending input stream. My question is therefore two-fold: 1. Is there a way to retrieve, parse, and print a custom XML-formatted error code sent by a web service using the plugins that are available in Java? 2. If the above is not possible, what other tools should I use or develop to handle such custom codes as described?

• A question on delegates and method parameters

  - by Srinivas Reddy Thatiparthy

  public class Program { delegate void Srini(string param); static void Main(string[] args) { Srini sr = new Srini(PrintHello1); sr += new Srini(PrintHello2); //case 2: sr += new Srini(delegate(string o) { Console.WriteLine(o); }); sr += new Srini(delegate(object o) { Console.WriteLine(o.ToString()); }); //case 4: sr += new Srini(delegate { Console.WriteLine(“This line is accepted,though the method signature is not Comp”); });//case 5 sr("Hello World"); Console.Read(); } static void PrintHello1(string param) { Console.WriteLine(param); } static void PrintHello2(object param) { Console.WriteLine(param); } } Compiler doesn't complain about the case 2(see the comment),well,the reason is straight forward since string inherits from object. ,along the same lines ,Why is it complaining for anonymous method types(see the comment //case 4:) that “Cannot convert anonymous method to delegate type 'DelegateTest.Program.Srini' because the parameter types do not match the delegate parameter types” where as in case of normal method it doesn't ?or am i comparing apples with oranges? Another case is why is it accepting anonymous method without parameters?

• LINQ to XML contents of child records.

  - by Fossaw

  I have this LINQ to XML enquiry... var Records = from Item in XDoc.Root.Elements("Item") where (string)Item.Element("ItemNumber") == item.ID.ToString select Item; ... where ItemNumber is a reference number used in the XML, (originally written by this program but manually edited by "others"), and item.ID is the database version of the same thing. The query executes, and I can test for the number of entries in the result fine... if (Records.Count() < 1) ... you get the idea. I have established that there is only one record. Each Item has several child fields. I want to test the values of the child fields are reasonable before passing them on to the database update sub-system. The XML is produced by the program, but edited by users, so I need to really check what is coming back. So I tried... if (DB_English.ToString() != Records.Elements("English").ToString()) ... DB_English is from the database, but the XML in Records, does not contain the contents of that field, it contains... System.Xml.Linq.Extensions+<GetElements>d__29`1[System.Xml.Linq.XElement] ... so, how do I get the value of this element in the XML file? I need to check the field in the XML has not been altered, (the manual editors of this data file are not potentially 100% reliable).

• ISBNdb Retrieving and Managing Info

  - by Pierre Sylvestre

  Given a set of databases how can one you get information on a book with given price first (which consist of the average of a hidden list of prices coming from different web site) and followed by an optional second option that shows the list of the different web site with their page? To take an example given a query for ISBN 9785554443331 - it returns "Chemistry the central science 11 edition" : new:$50 used good condition:$35 used poor condition:$20 If the return does not match with our product list an option to "click here to visit our partner" appears and which returns: Atextbook: $10 Btextbook: $10 Ctextbook: $9 Dtextbook: $8.50 I understand that the first search would be done simultaneous on the web and our database to determine whether or not we have the book and the web to get the average of the price of a given list of web site. Thank you in advance for the help

• Quickbooks integration: IPP/IDS: can these by used for actual data exchange?

  - by Parand

  Poking around options for integrating an online app with Quickbooks, I've made a lot of headway with QBWC, but it's fairly ugly. From an end user perspective the usability of QBWC is pretty low. Intuit is now pushing Intuit Partner Platform (IPP) and Intuit Data Services (IDS). I can't quite figure out what these are about: Is IPP limited to using Flex, or can it work with existing web apps? Are there APIs for actual data exchange? Is it possible to interact with desktop Quickbooks using IPP or IDS? If there is sample code, particularly in Python, some pointers would be great.

• Working with a database

  - by Susan

  I have an existing program for a bank account, the user can create an account then withdraw or deposit money to the account. As a transaction is processed, labels are being used to show the current information such as (Beginning Balance, Transaction Fee, Withdrawal Amount, and Ending Balance). Now, I need to be able to keep track of the transactions being processed in a SQL database. I know how to add a database to the project and then set it up to display all of the data from the table in a gridview. This is assuming that I manually entered data into the table; however, the table should be blank when the program starts and as I process transactions, then the data should be written to the table. How do I bind my existing fields (labels) to a datatable and send the text to the table. The book that I have is all related to just displaying the data that is already in the table and I have been through a couple of tutorial online and they seem to be about the same subject. I haven't found anything on how to do what I am looking for. Can someone help me out here. I don't mind references to other websites that might have the answer. Thanks, Susan

• Cygwin Cruisecontrol cannot execute commands

• Can SVG render partially if gzipped and chunk-transferred?

  - by Scott Stafford

  Hi - I have some large, dynamically generated SVGs that are being served over a relatively slow internet connection. I'm trying to optimize them to be viewable as fast as possible. If I set the server to Content-Encoding: gzip and Transfer-Encoding: chunked, will any SVG viewers take advantage of that and render it partially, as it is transferred? If not, are there other ways to get it to render as-it-streams? I could break it up into several SVG pieces but that will be a lot of work, I was hoping for server settings... The most common users use IE7 with the Adobe SVG Viewer plugin. I doubt it matters but I'm serving with C#/ASP.NET and IIS6.

• Binder and variadic template ends up in a segmentation fault

After spending some time with gdb and this program it seems to me that the addresses of the function and the class are mixed up and a call of the data address of the class isn't allowed. Moreover if I use the commented line instead everything works fine. Can anyone else reproduce this behavior and/or explain me what's going wrong here?

• Can I fill in an encypted PDF with iTextSharp?

  - by Cmpalmer

  I have a fillable, saveable PDF file that has an owner password (that I don't have access to). I can fill it out in Adobe reader, export the FDF file, modify the FDF file, and then import it. Then I tried to do it with iText(Sharp). I can't create a PdfStamper from my PdfReader because I didn't provide the owner password to the reader. Is there any way to do this programmatically or must I recreate the document? Even using FdfReader requires a PdfStamper. Am I missing anything? Anything legal that is - I'm pretty sure I could hack the document, but I can't. Ironically, recreating it would probably be ok.

• C++: Is there any good way to read/write without specifically stating character type in function nam

  - by Mark L.

  I'm having a problem getting a program to read from a file based on a template, for example: bool parse(basic_ifstream<T> &file) { T ch; locale loc = file.getloc(); basic_string<T> buf; file.unsetf(ios_base::skipws); if (file.is_open()) { while (file >> ch) { if(isalnum(ch, loc)) { buf += ch; } else if(!buf.empty()) { addWord(buf); buf.clear(); } } if(!buf.empty()) { addWord(buf); } return true; } return false; } This will work when I instantiate this class with <char>, but has problems when I use <wchar_t> (clearly). Outside of the class, I'm using: for (iter = mp.begin(); iter != mp.end(); ++iter ) { cout << iter->first << setw(textwidth - iter->first.length() + 1); cout << " " << iter->second << endl; } To write all of the information from this data struct (it's a map<basic_string<T>, int>), and as predicted, cout explodes if iter->first isn't a char array. I've looked online and the consensus is to use wcout, but unfortunately, since this program requires that the template can be changed at compile time (<char> - <wchar_t>) I'm not sure how I could get away with simply choosing cout or wcout. That is, unless there way a way to read/write wide characters without changing lots of code. If this explanation sounds awkwardly complicated, let me know and I'll address it as best I can.
