• Lamp with mod_fastcgi

  - by Jonathan

  Hi! I am building a cgi application, and now I would like it to be like an application that stands and parses each connection, with this, I can have all session variables saved in memory instead of saving them to file(or anyother place) and loading them again on a new connection I am using lamp within a linux vmware but I can't seem to find how to install the module for it to work and what to change in the httpd.conf. I tried to compile the module, but I couldn't because my apache isn't a regular instalation, its a lamp already built one, and it seems that the mod needs the apache directory to be compiled. I saw some coding examples out there, so I guess is not that hard once its runing ok with Apache Can you help me with this please? Thanks, Joe

• C# 'is' type check on struct - odd .NET 4.0 x86 optimization behavior

  - by Jacob Stanley

  Since upgrading to VS2010 I'm getting some very strange behavior with the 'is' keyword. The program below (test.cs) outputs True when compiled in debug mode (for x86) and False when compiled with optimizations on (for x86). Compiling all combinations in x64 or AnyCPU gives the expected result, True. All combinations of compiling under .NET 3.5 give the expected result, True. I'm using the batch file below (runtest.bat) to compile and test the code using various combinations of compiler .NET framework. Has anyone else seen these kind of problems under .NET 4.0? Does everyone else see the same behavior as me on their computer when running runtests.bat? #@$@#$?? Is there a fix for this? test.cs using System; public class Program { public static bool IsGuid(object item) { return item is Guid; } public static void Main() { Console.Write(IsGuid(Guid.NewGuid())); } } runtest.bat @echo off rem Usage: rem runtest -- runs with csc.exe x86 .NET 4.0 rem runtest 64 -- runs with csc.exe x64 .NET 4.0 rem runtest v3.5 -- runs with csc.exe x86 .NET 3.5 rem runtest v3.5 64 -- runs with csc.exe x64 .NET 3.5 set version=v4.0.30319 set platform=Framework for %%a in (%*) do ( if "%%a" == "64" (set platform=Framework64) if "%%a" == "v3.5" (set version=v3.5) ) echo Compiler: %platform%\%version%\csc.exe set csc="C:\Windows\Microsoft.NET\%platform%\%version%\csc.exe" set make=%csc% /nologo /nowarn:1607 test.cs rem CS1607: Referenced assembly targets a different processor rem This happens if you compile for x64 using csc32, or x86 using csc64 %make% /platform:x86 test.exe echo =^> x86 %make% /platform:x86 /optimize test.exe echo =^> x86 (Optimized) %make% /platform:x86 /debug test.exe echo =^> x86 (Debug) %make% /platform:x86 /debug /optimize test.exe echo =^> x86 (Debug + Optimized) %make% /platform:x64 test.exe echo =^> x64 %make% /platform:x64 /optimize test.exe echo =^> x64 (Optimized) %make% /platform:x64 /debug test.exe echo =^> x64 (Debug) %make% /platform:x64 /debug /optimize test.exe echo =^> x64 (Debug + Optimized) %make% /platform:AnyCPU test.exe echo =^> AnyCPU %make% /platform:AnyCPU /optimize test.exe echo =^> AnyCPU (Optimized) %make% /platform:AnyCPU /debug test.exe echo =^> AnyCPU (Debug) %make% /platform:AnyCPU /debug /optimize test.exe echo =^> AnyCPU (Debug + Optimized) Test Results When running the runtest.bat I get the following results on my Win7 x64 install. > runtest 32 v4.0 Compiler: Framework\v4.0.30319\csc.exe False => x86 False => x86 (Optimized) True => x86 (Debug) False => x86 (Debug + Optimized) True => x64 True => x64 (Optimized) True => x64 (Debug) True => x64 (Debug + Optimized) True => AnyCPU True => AnyCPU (Optimized) True => AnyCPU (Debug) True => AnyCPU (Debug + Optimized) > runtest 64 v4.0 Compiler: Framework64\v4.0.30319\csc.exe False => x86 False => x86 (Optimized) True => x86 (Debug) False => x86 (Debug + Optimized) True => x64 True => x64 (Optimized) True => x64 (Debug) True => x64 (Debug + Optimized) True => AnyCPU True => AnyCPU (Optimized) True => AnyCPU (Debug) True => AnyCPU (Debug + Optimized) > runtest 32 v3.5 Compiler: Framework\v3.5\csc.exe True => x86 True => x86 (Optimized) True => x86 (Debug) True => x86 (Debug + Optimized) True => x64 True => x64 (Optimized) True => x64 (Debug) True => x64 (Debug + Optimized) True => AnyCPU True => AnyCPU (Optimized) True => AnyCPU (Debug) True => AnyCPU (Debug + Optimized) > runtest 64 v3.5 Compiler: Framework64\v3.5\csc.exe True => x86 True => x86 (Optimized) True => x86 (Debug) True => x86 (Debug + Optimized) True => x64 True => x64 (Optimized) True => x64 (Debug) True => x64 (Debug + Optimized) True => AnyCPU True => AnyCPU (Optimized) True => AnyCPU (Debug) True => AnyCPU (Debug + Optimized) tl;dr

• Error C2491 on C source with Visual studio 8

  - by Tobia

  i'm really noob in C. I just need to compile a ANSI C source to get a dll. During compilation i get this error: C2491: 'SelectML': definition of dllimport function not allowed Where SelectML is a public function with this definition: int CALLINGCONV SelectML(WORD fid, int nSlot) { WORD SW; int x; BYTE pSend[2]; pSend[0]=(BYTE)((fid&0xff00)>>8); pSend[1]=(BYTE)(fid&0x00ff); x=SendAPDUML(hCards[nSlot],APDU_SELECT,2,0,pSend,0,&SW); if (x!=C_OK) return x; if (SW!=0x9000) return SW; return C_OK; } I'm sure the C source is good, maybe it is just a Visual Studio configuration...

• Selecting Entity Data Model Laguage -- Visual C# source file generated even when i select VB

  - by Nickson

  Am adding an Entity Data Model to an ASP.NET website. When i Add New Item to the website and select ADO.NET Entity Data Model, am asked for the model name and language. I go a head and select Visual Basic as the language, the model is added and the site can compile with out any issues. however, the model it adds a ModelName.Designer.cs source file, instead of a ModelName.Designer.vb source file. am thinking this is strange as its happening with only one of my website. my other sites have .vb designer source file for their Entity Data Models. The site still compiles with out any errors but am afraid some thing is not right. any one experienced this?, is this normal behavior?

• cmake and visual studio

  - by robUK

  Hello, gcc 4.4.2 / Visual Studio C++ 2008 I have been using cmake on linux, without any problems. Now I have ported by application to run on windows. I generated the solution files using cmake -G "Visual Studio 9 2008 ../src" However, I know that cmake only creates a Makefile that is used by the compiler to build your application. I open my solution in Visual Studio, I press the F7 key to compile. I am wondering does it actually use the Makefile that was generated by cmake? Or it is just compiling the application like any normal visual studio program? Many thanks for any advice,

• ASP.NET plug-in architecture, settings problem

  - by Xaqron

  I want to divide business layer (BLL) of an asp.net application into multiple components. Each component is a .NET class library which is compiled as a standalone DLL. These components should have their own configuration files. For example "MyNameSpace.Users.dll" contains classes about users of the website and there's a password policy to check if password length is at least x characters. When webmaster edits the config file of this DLL and set x to y then component (DLL) should use new value (y) in the future and enforce passwords to be at least y characters. I want each component as a single project and compile them separaely (and not to put all projects in a solution in Visual Studio), and put the DLLs of these libraries into the "Bin" folder of my ASP.NET application. Is it possible ? Where should I put these config files ?

• Reinstall TeamCity when Tomcat becomes corrupt

  - by dodegaard

  I've got a TeamCity 4 installation where tomcat has bit the dust with the following error "The APR Based Apache Tomcat Native library which allows for optimal performance in production environments was not found in java.library path". It appears this started happening once the JDK was installed on the server to allow for a compile. The JDK has been removed and the JRE reinstalled but still no go. My question is should I reinstall TeamCity completely or is there a way to simply reinstall tomcat so I don't hose the configuration? Your help is greatly appreciated.

• How do I use timezones with a datetime object in python?

  - by jidar

  How do I properly represent a different timezone in my timezone? The below example only works because I know that EDT is one hour ahead of me, so I can uncomment the subtraction of myTimeZone() import datetime, re from datetime import tzinfo class myTimeZone(tzinfo): """docstring for myTimeZone""" def utfoffset(self, dt): return timedelta(hours=1) def myDateHandler(aDateString): """u'Sat, 6 Sep 2008 21:16:33 EDT'""" _my_date_pattern = re.compile(r'\w+\,\s+(\d+)\s+(\w+)\s+(\d+)\s+(\d+)\:(\d+)\:(\d+)') day, month, year, hour, minute, second = _my_date_pattern.search(aDateString).groups() month = [ 'JAN', 'FEB', 'MAR', 'APR', 'MAY', 'JUN', 'JUL', 'AUG', 'SEP', 'OCT', 'NOV', 'DEC' ].index(month.upper()) + 1 dt = datetime.datetime( int(year), int(month), int(day), int(hour), int(minute), int(second) ) # dt = dt - datetime.timedelta(hours=1) # dt = dt - dt.tzinfo.utfoffset(myTimeZone()) return (dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second, 0, 0, 0) def main(): print myDateHandler("Sat, 6 Sep 2008 21:16:33 EDT") if __name__ == '__main__': main()

• Skype Mac API - Use AppleScript or 5 year old API?

  - by Andrew

  I have a x86_64 app that I would like to have optionally read Skype status messages. However, the 5 year old skype mac framework is 32-bit, and if there is a way to have that compile within a 64-bit app, I haven't found it. My question is, basically, how should I go about doing this? I really only need to get and set the USERSTATUS AWAY/ONLINE string. Using AppleScript, a "Should Skype allow this" dialog pops up... every time. This is highly inefficient and downright irritating. Advice? I'm considering writing a 32-bit CLI wrapper, but that seems like overkill.

• How to implement dynamic queries for MNesia?

  - by Kerem

  I'm trying to implement a function that generates dynamic queries for MNesia. For example, when function is called with these arguments; dyn_query(list, person, [name, age], ["jack", 21]) I want to query MNesia to list items whose name is "jack" and age is 21 in person table. I've tried to implement this by using qlc:q(ListComprehension) and qlc:string_to_handle("ListComprehension"). First failed because of compile errors, compiler didn't let me to use functions instead of ListComprehentions and variables instead of record names like "Item#Table.Member". Second failed, because erl_eval couldn't handle records and throwed exceptions like {undefined_record, person}. Which method should I use? How could i solve these problems? Or should I use a different method? Thanks.

• Attempt to use DLL results in error.

  - by abhi

  I am using a library (DLL) that uses the Oracle.DataAccess DLL to connect to the database. I am doing in in C# .NET framework 3.5 When I attempt to compile, the compilation takes place, but the executable throws this error message. Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture= neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format. Is there some way to get around this? What could be causing this to happen?

• Compilation error on a user control

  - by MikeP

  I'm stumped! We have a user control for managing account information. We use this particular control on two pages. On one page, everything works perfectly and meets our expectation. On the second page however we receive compilation errors stating that: "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\lrpcentral\0e987bea\6719c8b6\App_Web_PageThatFails.aspx.f3d462c1.oi52bvii.0.cs(172): error CS0433: The type 'xxxx_ascx' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\APPLICATIONNAME\0e987bea\6719c8b6\App_Web_xxxx.ascx.cdcab7d2.xbnvt2za.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\APPLICATIONNAME\0e987bea\6719c8b6\App_Web_eix7xllr.dll' My problem is similar to Cyril's but the "delete everything from Temp" is not an option for me, and Cyril's solution does not apply since the only variable we have is contained in the designer file, which is not deployed to our production environment (we pre-compile). After reading David's answer (here) I examined my directories for circular dependency and was unable to find any. Structure: Top Level Page that works Control Directory A Page that causes the error

• BNRPersistence on the iPhone, and NSDocument

  - by jammur

  I'm trying to get BNRPersistence running in an iPhone app, but I'm having a problem that I have no idea how to solve. Keep in mind I'm relatively new to iPhone dev. The problem is that BNRStoreDocument subclasses NSDocument, which exists in the Cocoa framework and thus isn't available on the iPhone. So obviously I'm getting compile errors that it can't find NSDocument. The developer of BNRPersistence states that it works on the iPhone, so I'm sure there a solution, I just don't what it is. Any help would be greatly appreciated!

So far I have just tried to get it to match the string to no avail. Can anyone point out a solution to this. Thanks

• Subversion: Ignore a Directory in the Repo on Commit

  - by Charles

  I have all the boost header files in this repository and when I do a check in it takes a really long time to scan all those files that will never change. Because I want users that checkout the project to be able to compile without installing boost I am in a pickle. I want to checkout everything, and then ignore updates (there will never be any) on a directory. Tortoise svn has a ignore-on-commit change list, but I cannot find anyway to add an entire directory to this list, and I do not fancy the idea of 'modifying' all the boost files so I can add them to this change list. Is there a simple solution?

• Stack trace for C++ using gcc

  - by dimba

  We use stack traces in proprietary assert like macro to catch developer mistakes - when error is caught, stack trace is printed. I find gcc's pair backtrace()/backtrace_symbols() methods insufficient: Names are mangled No line information 1st problem can be resolved by abi::__cxa_demangle. However 2nd problem s more tough. I found replacement for backtrace_symbols(). This is better than gcc's backtrace_symbols(), since it can retrieve line numbers (if compiled with -g) and you don't need to compile with -rdynamic. Hoverer the code is GNU licenced, so IMHO I can't use it in commercial code. Any proposals?

• Call Ruby class over java with jruby

  - by r2

  Hi all If I implement a class in ruby and compile it with jrubyc than it is not possible to call it from a java class directly if I start it with java. If I see this right I have to use org.jruby.embed... to implement a wrapper wich takes a class name and a metod to call my ruby class. Do I have to do this also if I start the application with jruby? In my current project I start java workflow engine completely with jruby. The workflow has to call a method in a ruby class which he cant find. Maybe easier to understand: [ruby_class] <-----has to call----. | jruby [ruby_start_script] --starts--> [java wfe]

• C++/CLI com-Interop: Exposing a reference type property to VBA

  - by Adam

  After long hours of investigation on exposing C# property that accepts a reference type to VBA, I concluded that it was not possible. In brief, a C# property that is of type double[] or even an object cannot be consumed in VBA like this: ' Compile Error: Function or interface marked as restricted, ' or the function uses an Automation type not supported in Visual Basic oComExposedEarlyBinding.ObjectArray = VBArray ' Run-time error 424: Object required oComExposedEarlyBinding.PlainObject = VBArray Or for more details: C# property exposed to VBA (COM) : Run-time error '424': Object required I would like to know if C++/CLI would support such an option? i.e. Allowing a reference-type property to be exposed to VBA so that a syntax like the above is valid. N.B. You can achieve this by using late binding, but losing the intellisense is not an option.
