• .Net OutOfMemory on Server but not Desktop

  - by Jörg Battermann

  Is it possible that the .Net framework behaves differently when it comes to garbage collection / memory limitations on server environments? I am running explicitly x86 compiled apps on a 64bit server machine with 32gbs of physical ram and I am running out of memory (SystemOutOfMemoryException) even though nothing but that particular app is running and the server/all other apps utilize 520mb total.. but I cannot reproduce that behaviour on my own (client win7) machine. Now I know that the app -is- memory intensive, but why is it causing problems on the server and not on the client?

• Considering getting into reverse engineering/disassembly

  - by Zombies

  Assuming a decent understanding of assembly on common CPU architectures (eg: x86), how can one explore a potential path (career, fun and profit, etc) into the field of reverse engineering? There is so little educational guides out there so it is difficult to understand what potential uses this has today (eg: is searching for buffer overflow exploits still common, or do stack monitoring programs make this obselete?). I am not looking for any step by step program, just some relevant information such as tips on how to efficiently find a specific area of a program. Basic things in the trade. As well as what it is currently being used for today. So to recap, what current uses does reverse engineering yield today? And how can one find some basic information on how to learn the trade (again it doesn't have to be step-by-step, just anything which can through a clue would be helpful).

• Get Process ID of Program Started with C# Process.Start

  - by ThaKidd

  Thanks in advance of all of your help! I am currently developing a program in C# 2010 that launches PLink (Putty) to create a SSH Tunnel. I am trying to make the program able to keep track of each tunnel that is open so a user may terminate those instances that are no longer needed. I am currently using System.Diagnostics.Process.Start to run PLink (currently Putty being used). I need to determine the PID of each plink program when it is launched so a user can terminate it at will. Question is how to do that and am I using the right .Net name space or is there something better? Code snippet: private void btnSSHTest_Click(object sender, EventArgs e) { String puttyConString; puttyConString = "-ssh -P " + cboSSHVersion.SelectedText + " -" + txtSSHPort.Text + " -pw " + txtSSHPassword.Text + " " + txtSSHUsername.Text + "@" + txtSSHHostname.Text; Process.Start("C:\\Program Files (x86)\\Putty\\putty.exe", puttyConString); }

• PHPIniDir broken under windows 7?

  - by bobbyb

  I had a server running on a windows xp machine using apache2 with php and mysql. I've recently upgraded to windows 7 and have been having trouble getting it to work. Apache works fine and php works, but I can't seem to get it to work with a php.ini file. When I set PHPIniDir to a directory with a php.ini file, the Apache service does NOT start. When I set PHPIniDir to a directory with NO php.ini file, the Apache service does start. When I leave out PHPIniDir, the Apache service does not start. Has anyone found a fix for this problem? Thanks! EDIT: PHPIniDir "C:\Windows" #works (no php.ini file) PHPIniDir "C:\Program Files (x86)\php\" #does not work (contains php.ini file) i enable at most one at any given time.

• Are indivisible operations still indivisible on multiprocessor and multicore systems?

  - by Steve314

  As per the title, plus what are the limitations and gotchas. For example, on x86 processors, alignment for most data types is optional - an optimisation rather than a requirement. That means that a pointer may be stored at an unaligned address, which in turn means that pointer might be split over a cache page boundary. Obviously this could be done if you work hard enough on any processor (picking out particular bytes etc), but not in a way where you'd still expect the write operation to be indivisible. I seriously doubt that a multicore processor can ensure that other cores can guarantee a consistent all-before or all-after view of a written pointer in this unaligned-write-crossing-a-page-boundary situation. Am I right? And are there any similar gotchas I haven't thought of?

  I am using mysql 5.1 and mysql gems version is 2.73 This is giving the following error message when I try to run it from a limited account in my XP.

• VS 2008 unstable after "Stop Debugging"

  - by liys

  This was on Windows Server 2003 X86, VSTS 9.0.30729.1 SP I used "Attach to process" to debug the program, but recently when I "Stop Debugging" by "shift + f5", I was prompted with an error saying "VS has an internal error and will be unstable". After that all the debug related menu items were disabled e.g. "Start debugging" and "attach to process" etc., even when I forcibly closed the program the situation remained, leaving me the only option to restart the solution. The only reason I can think of causing this is that I forcibly kill the process a lot, in order to able to rebuild it quickly, other than that I didn't do anything abnormal to VS. another sympton: when I tried to close the VS normally, I was prompted with "source file [] does not belong to the project being debugged" for all the files I opened inside of IDE, but the file does belong to the project. Thanks for any reply.

• How can I increase my application memory, till using the VirtualAlloc function, with the WOW64?

  - by fishbein

  I have application that runs on x86 32Win and we use 1.2Gbyte memory which allocated from the function VirtualAlloc(to prevent page faults). I really want to increase my application memory so I recompiled my project under MSDVE 2008 with wow64 (OS Exp 64Bit). I tried to allocate more than 2Gbyte and the function VirtualAlloc return error. I even tried to set the flag LARGEADDRESSWARE to on, and the result was the same! How can I increase my application memory, till using the VirtualAlloc function, with the WOW64?

• $(MSBuildStartupDirectory) in Visual Studio points to different places on different machines

  - by skolima

  In a large solution, I'm integrating Gendarme into Visual Studio 2008 compilation process. I am using GendarmeMsBuild task along with a .targets file to add a AfterBuild target to every project in the solution. I am looking for a way to import this file into .csproj files in a way that wouldn't require me to change the include path (the projects have different nesting levels). Apart from using NuGet SolutionDir variable, best way to solve this seemed to be to use $(MSBuildStartupDirectory). However, as it turns out, on some machines, using the same version of VS 2008 (as same updates installed, as far as I was able to check) this resolves to the solution directory, and on others to c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE. How can I either get this to always resolve to the solution folder or obtain the base folder in another consistent way?

• Why Aren't Programs Written In Assembly More Often?

  - by mudge

  It seems to be a mainstream opinion that assembly programming takes longer and is more difficult to program in than a higher level language such as C. Therefore it seems to be recommend or assumed that it is better to write in a higher level language for these reasons and for the reason of better portability. Recently I've been writing in x86 assembly and it has dawned on me that perhaps these reasons are not really true, except perhaps portability. Perhaps it is more of a matter of familiarity and knowing how to write assembly well. I also noticed that programming in assembly is quite different than programming in an HLL. Perhaps a good and experienced assembly programmer could write programs just as easily and as quickly as an experienced C programmer writing in C. Perhaps it is because assembly programming is quite different than HLLs, and so requires different thinking, methods and ways, which makes it seem very awkward to program in for the unfamiliar, and so gives it its bad name for writing programs in. If portability isn't an issue, then really, what would C have over a good assembler such as NASM?

• Writing a simple batch file to setup a variable?

  - by Sam

  I want to write a simple batch file where i want to setup a environment variable based on the machine architecture. It is as below: set ARCH=%PROCESSOR_ARCHITECTURE% echo %ARCH% if %ARCH%==x86 ( set JAVA_ROOT=C:\Progra~1\Java\j2re1.4.2_13 ) else ( set JAVA_ROOT=C:\Progra~2\Java\j2re1.4.2_13 ) echo JAVA_ROOT is %JAVA_ROOT% On 64-bit machine where the architecture is 'AMD64' the JAVA_ROOT will be displayed as 'C:\Progra~2\Java\j2re1.4.2_13' at the echo statement. But when i run an application that uses this file, the first value of JAVA_ROOT would be picked up 'C:\Progra~1\Java\j2re1.4.2_13'. I don't have any idea why it goes in the 'if' part even though i am running this on 64-bit Windows7. When i echoed the

• More memory usage for IIS 6 asp.net 2.0 on webserver 2003

  - by Alan King

  Running a webserver 2003 SP2 (x86) with IIS 6 and asp.net 2. The box is running mostly dynamic asp pages connecting to a sql 2008 server. At any given time there is over 1 gig of memory available out of the 2 gig in the box. It seems like there would be a way for it to make better use of the free memory. It is using a default machine.config file and default http.sys. I would like to maximize incoming internet connections and database connections. Is there something I can do to make better use of the available memory?

• Maven: Finding out whether running in a 32 or a 64 bit JVM

  How can I enable or disable a maven profile based on whether the VM that is executing maven is a 32 bit or a 64 bit JVM? I tried this: <activation> <os> <arch>x86</arch> </os> </activation> or amd64 respectively to detect a 32/64 bit VM, but this fails on a 32 bit VM running on a 64 bit Windows as it activates the 64 bit profile.

• Are memory barriers necessary for atomic reference counting shared immutable data?

  - by Dietrich Epp

  I have some immutable data structures that I would like to manage using reference counts, sharing them across threads on an SMP system. Here's what the release code looks like: void avocado_release(struct avocado *p) { if (atomic_dec(p->refcount) == 0) { free(p->pit); free(p->juicy_innards); free(p); } } Does atomic_dec need a memory barrier in it? If so, what kind of memory barrier? Additional notes: The application must run on PowerPC and x86, so any processor-specific information is welcomed. I already know about the GCC atomic builtins. As for immutability, the refcount is the only field that changes over the duration of the object.

• Install driver by using C++

  - by user296359

  Hi, This is a question about installing driver. I have the following files : aaa.cat aaa.inf x86\ttt.sys I can install this driver by clicking "update driver" in device manager. But now I need to install this driver on Windows (XP, Vista and Win7) by using C++. How could I do this? On the other hand, I can't use install shield or other tool to do the job. That is why I am asking this question. Thanks in advance. I have found this page, which mentioned SetupInstallFile and SetupInstallFileEx functions. Is this the answer? http://msdn.microsoft.com/en-us/library/aa376958%28VS.85%29.aspx

• CUDA & VS2010 problem

  - by Kristian D'Amato

  I have scoured the internets looking for an answer to this one, but couldn't find any. I've installed the CUDA 3.2 SDK (and, just now, CUDA 4.0 RC) and everything seems to work fine after long hours of fooling around with include directories, NSight, and all the rest. Well, except this one thing: it keeps highlighting the <<< >>> operator as a mistake. Only on VS2010--not on VS2008. On VS2010 I also get several warnings of the following sort: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xdebug(109): warning C4251: 'std::_String_val<_Ty,_Alloc>::_Alval' : class 'std::_DebugHeapAllocator<_Ty>' needs to have dll-interface to be used by clients of class 'std::_String_val<_Ty,_Alloc>' Anyone know how this can be fixed?

• Visual Studio namespace errors after deleting userControls

Whatever I do I can not build successfully my project. I did not touch the SchoolAdministrationUC.xaml file , but I deleted 3 other UserControls also located in the path: TBM\View\SchoolclassAdministration\ Error message from VS: Error 1 The type or namespacename "SchoolclassAdministration" is in namespace "TBM.View" not available.

• How to change the assemblyIdentity of a program

  - by David

  I want to hide the tool I used to create an .exe file. I am not doing anything illegal, I just want to protect my intellectual property from being copied. If I open the exe file in a text editor I see the following section. <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="XXX.XX" processorArchitecture="X86" name="Microsoft.Windows.NameOfTheTool" type="win32" /> </assembly> I have attempted to change the name to: name="Microsoft.Windows.SomeOtherName" This resulted in the following message when I attempted to execute the file. "This application has failed to start because its side-by-side configuration is incorrect." How can I solve this?

• Potential problems porting to different architectures

  - by Brendan Long

  I'm writing a Linux program that currently compiles and works fine on x86 and x86_64, and now I'm wondering if there's anything special I'll need to do to make it work on other architectures. What I've heard is that for cross platform code I should: Don't assume anything about the size of a pointer, int or size_t Don't make assumptions about byte order (I don't do any bit shifting -- I assume gcc will optimize my power of two multiplication/division for me) Don't use assembly blocks (obvious) Make sure your libraries work (I'm using SQLite, libcurl and Boost, which all seem pretty cross-platform) Is there anything else I need to worry about? I'm not currently targeting any other architectures, but I expect to support ARM at some point, and I figure I might as well make it work on any architecture if I can. Also, regarding my second point about byte order, do I need to do anything special with text input? I read files with getline(), so it seems like that should be done automatically as well.

• Unwanted SQLite inserted in \bin

  - by wilk

  I am using Visual Studio 2010 and using web deployment to promote the .Net MVC site to specific environments. I installed Elmah, and it worked great on my DEV environment, but when I pushed TEST, I got exceptions because SQLite was not a good format. I am not using SQLite in Elmah or otherwise that I know of. I have removed all visible refernces to SQLite, and I have removed the .dll from all configuration bin directories. But it still gets inserted with each build. I realize the exception problem is that SQLite cannot be built for CPU Any, and my environments vary from x86 to x64. But I would prefer SQLite to not even be present. I have since uninstalled Elmah, and SQLite is still inserted into the \bin directory. I have now re-installed Elmah, and I manually delete the SQLite.dll from \bin after each build. How can I determine what is causing SQLite to be inserted into my \bin after each build?
