  • Looking for: C/C++ Regex library that supports Named Captures

    - by user318811
    I'm thinking about writing a small application that will help me mass rename files. I currently use an application named 'RegexRenamer', which (I'm assuming) uses the .NET regex engine. The application is fine, but is sort of clunky. So what I'm looking for is a C/C++ regex library that I can build my custom program off of. Anything that is small and lightweight is preferred (.Net seems heavy). Thanks.

  • LINQ timed out while the same query works great in SQL

    - by oshafran
    Hi I am getting Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Data.SqlClient.SqlException (0x80131904): Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. When I run the SAME query in the SQL query program I get result within seconds, and in LINQ it takes forever and fails. What can cause this??? Thanks!

  • How to write a CXF client with implicit security header.

    - by Jayaprakash
    Hi everyone, I have to access a service which is developed using different framework. The client program is using CXF. I dont have access to the provider environment so I cannot use any config files (Cxf.xml, cxfservlet.xml etc..). I need to access the webservice with implicit security header (UsernameTokenType, oasis-200401-wss-wssecurity-secext-1.0.xsd) . Can anyone throw some light on this?..

  • Is it possible to make an OS in python?

    - by None
    I was just wondering if it was possible to make an operating system in python. Nothing fancy. Maybe not even a "real" operating system with a kernel and all. Just a python program that is run when someone inserts the disc containing it that will make a fullscreen display on top of the installed os.

    - by Adrian
    Would anyone know how to test for the appearance of a Toast message on an Activity? I'm using code similar to what the OP posted on this question for testing my program flow from one activity to the next. I'd also like to be able to test for toast messages on particular activities.

  • What programming language is the most English-like?

    - by asmeurer
    I'm mainly a Python programmer, and it is often described as being "executable pseudo-code". I have used a little bit of AppleScript, which seems to be the most English-like programming language I have ever seen, because almost operators can be words, and it lets you use "the" anywhere (for example, this stupid example I just came up with: firstnumber = 1 secondnumber = 2 if the firstnumber is equal to the secondnumber then set the sum to 5 end if is a valid AppleScript program. Are there any programming languages that are even more English-like than these?

  • Security of executing a command from php

    - by Nicolò Martini
    I'm writing a web application in which i use several thirdy party commands calling them with the exec function in PHP (for example, I render Latex formulas through a command-line program). My question is: what are the security issues of executing external command-line programs in php? What I have to be aware of? Can you give me a list of points to check? Thanks in advance.

    - by wasim
    I need to create a little program that creates a backup copy of some DBF files on demand. the files are used by a custom designed Web application. Is it safe to copy a dbf file while it is open or do I need to close the web server so the files are released before safely creating a backup?

    I'm working on getting my database to talk to my Java programs. What do I need to get started? Having already read through (and been thoroughly confused, something that does not happen often) with some other turorials I figured I'd best ask here. How do I import a jar file from the local directory? Can someone give me a quick and dirty sample program using the JDBC?

  • How to listen to keyboard events in GWT table?

    - by Olaf Mertens
    In my GWT program I have a table that has a selected row. I'd like to move the row selection with the up- and down-keys on the keyboard. So I have to catch the key events somehow. The GWT docs handle key events in input fields only. But I don't have an input field! Is this possible at all? Maybe it is a DOM/Javascript restriction that GWT cannot work around...

  • Quickly read pgm header with comments in C

    - by Vi
    Quickly write PGM header is fprintf(f, "P5 %d %d 255\n", width, height); Quickly read PGM header is fscanf(f, "P5%d%d%*d\n"); // now can read the data from f, but it fails when the header contains comments (like if saved by GIMP). How to read PGM header in more compatible way (without a lot of code or extra dependencies, I don't want my program to cease being oneliner because of this)?

    The challenge The shortest code by character count to output a spider web with rings equal to user's input. A spider web is started by reconstructing the center ring: \_|_/ _/ \_ \___/ / | \ Then adding rings equal to the amount entered by the user. A ring is another level of a "spider circles" made from \ / | and _, and wraps the center circle. Input is always guaranteed to be a single positive integer.

  • php POST and non-english language passes empty

    - by haim evgi
    I'm trying to program a Hebrew site with a search option. I am using php 5 with Apache 2.2, on a Debian 5 (Lenny) with appropriate code pages enabled. I am using _POST to pass arguments to a script. If I pass English word to the script everything works, but when I use Hebrew nothing is passed through the POST function. When I use ECHO to show _POST, the variable is empty. What might be the problem?

  • Why does Git.pm on cygwin complain about 'Out of memory during "large" request?

    - by Charles Ma
    Hi, I'm getting this error while doing a git svn rebase in cygwin Out of memory during "large" request for 268439552 bytes, total sbrk() is 140652544 bytes at /usr/lib/perl5/site_perl/Git.pm line 898, <GEN1> line 3. 268439552 is 256MB. Cygwin's maxium memory size is set to 1024MB so I'm guessing that it has a different maximum memory size for perl? How can I increase the maximum memory size that perl programs can use? update: This is where the error occurs (in Git.pm): while (1) { my $bytesLeft = $size - $bytesRead; last unless $bytesLeft; my $bytesToRead = $bytesLeft < 1024 ? $bytesLeft : 1024; my $read = read($in, $blob, $bytesToRead, $bytesRead); //line 898 unless (defined($read)) { $self->_close_cat_blob(); throw Error::Simple("in pipe went bad"); } $bytesRead += $read; } I've added a print before line 898 to print out $bytesToRead and $bytesRead and the result was 1024 for $bytesToRead, and 134220800 for $bytesRead, so it's reading 1024 bytes at a time and it has already read 128MB. Perl's 'read' function must be out of memory and is trying to request for double it's memory size...is there a way to specify how much memory to request? or is that implementation dependent? UPDATE2: While testing memory allocation in cygwin: This C program's output was 1536MB int main() { unsigned int bit=0x40000000, sum=0; char *x; while (bit > 4096) { x = malloc(bit); if (x) sum += bit; bit >>= 1; } printf("%08x bytes (%.1fMb)\n", sum, sum/1024.0/1024.0); return 0; } While this perl program crashed if the file size is greater than 384MB (but succeeded if the file size was less). open(F, "<400") or die("can't read\n"); $size = -s "400"; $read = read(F, $s, $size); The error is similar Out of memory during "large" request for 536875008 bytes, total sbrk() is 217088 bytes at mem.pl line 6.

  • MS Access MSChart.Graph.8 not printing

    - by Tanj
    Software: Microsoft Access 2007 SP2 Database File Version: Access 2000 I have an access program that I inherited from a previous employee. It uses forms for reports and since I don't have much experience in access I have continued to do this. I have created a copy of the program for another project and modified it to suit. I am having trouble getting more then one chart to print. All the charts display in form view, they all have the same properties (excepting data, position, etc.) For some reason they are not printing. They don't even show up in the print preview. I am thinking it must be something with the graphs themselves as they sometimes lose all information. I have to open the graphs in edit mode and change the data source from column to row and back again so that it gets redrawn. (Refresh doesn't fix it) So right now I don't even have a clue as to where to look so ideas are welcome. Edit #1 It seems to be a problem with linking to an unbound form. Subform Field Linker: Can't build a link between unbound forms. The query for the main form is SELECT tTest.ixTest, tMotorTypes.ixMotorType, tMotorTypes.asMotorType, tMotorTypes.fDeprecated, tTestType.asTest, tTest.asSerialNum, tTest.asOrderNum, tTest.asFrameNum, tTest.asRotorNum, tTest.asOperator, tTest.iStation, tTest.dtTestDate, tTest.ixTestType FROM tMotorTypes INNER JOIN (tTestType INNER JOIN tTest ON tTestType.ixTestType=tTest.ixTestType) ON tMotorTypes.ixMotorType=tTest.ixMotorType; The query for the chart is: SELECT qGraphRSTTemperatures.Frequency, qGraphRSTTemperatures.[Drive End], qGraphRSTTemperatures.[Non Drive End], qGraphRSTTemperatures.[Air In], qGraphRSTTemperatures.Core FROM qGraphRSTTemperatures ORDER BY qGraphRSTTemperatures.ixTemperature; Query qGraphRSTTemperatures: SELECT tElectricalData.dblFrequency AS Frequency, tTemperatures.dblDrvEnd AS [Drive End], tTemperatures.dblNonDrvEnd AS [Non Drive End], tTemperatures.dblAirIn AS [Air In], tTemperatures.dblCore AS Core, tSubTest.ixTest, tTemperatures.ixTemperature FROM (tSubTest INNER JOIN tElectricalData ON tSubTest.ixSubTest = tElectricalData.ixSubTest) LEFT JOIN tTemperatures ON tElectricalData.ixElectrical = tTemperatures.ixElectrical WHERE (((tSubTest.ixSubTestType)=5)) ORDER BY tSubTest.ixTest, tTemperatures.ixTemperature; So how come, in the form view it shows the graph with the correct data when linked thus: Child field: ixTest Master field: ixTest but won't print the graph. The graph will print if I remove the links, but then I have all the data from chart query as it is not limited by ixTest. edit #2 It seems to be a data retrieval/rendering issue in printing. Is there anything in printing that changes the context of records with respect to parent/child relationships?
