  • Python virtualenv questions

    - by orokusaki
    I'm using VirtualEnv on Windows XP. I'm wondering if I have my brain wrapped around it correctly. I ran virtualenv ENV and it created C:\WINDOWS\system32\ENV. I then changed my PATH variable to include C:\WINDOWS\system32\ENV\Scripts instead of C:\Python27\Scripts. Then, I checked out Django into C:\WINDOWS\system32\ENV\Lib\site-packages\django-trunk, updated my PYTHON_PATH variable to point the new Django directory, and continued to easy_install other things (which of course go into my new C:\WINDOWS\system32\ENV\Lib\site-packages directory). I understand why I should use VirtualEnv so I can run multiple versions of Django, and other libraries on the same machine, but does this mean that to switch between environments I have to basically change my PATH and PYTHON_PATH variable? So, I go from developing one Django project which uses Django 1.2 in an environment called ENV and then change my PATH and such so that I can use an environment called ENV2 which has the dev version of Django? Is that basically it, or is there some better way to automatically do all this (I could update my path in Python code, but that would require me to write machine-specific code in my application)? Also, how does this process compare to using VirtualEnv on Linux (I'm quite the beginner at Linux).

  • Per-process CPU usage on Win95 / Win98 / WinME

    - by Hugh Allen
    How can you programmatically measure per-process (or better, per-thread) CPU usage under windows 95, windows 98 and windows ME? If it requires the DDK, where can you obtain that? Please note the Win9x requirement. It's easy on NT. EDIT: I tried installing the Win95/98 version of WMI, but Win32_Process.KernelModeTime and Win32_Process.UserModeTime return Null (as do most Win32_Process properties under win9x).

  • Gacutil.exe successfully adds assembly, but assembly missing from GAC. Why?

    - by Ben McCormack
    I'm running GacUtil.exe from within Visual Studio Command Prompt 2010 to register a dll (CatalogPromotion.dll) to the GAC. After running the utility, it says Assembly Successfully added to the cache, and running gacutil /l CatalogPromotionDll shows that the GAC contains the assembly, but I can't see the assembly when I navigate to C:\WINDOWS\assembly from Windows Explorer. Why can't I see the assembly in WINDOWS\assembly from Windows Explorer but I can see it using gacutil.exe? Background: Here's what I typed into the command prompt for VS Tools: C:\_Dev Projects\VS Projects\bmccormack\CatalogPromotion\CatalogPromotionDll\bin \Debuggacutil /i CatalogPromotionDll.dll Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.1 Copyright (c) Microsoft Corporation. All rights reserved. Assembly successfully added to the cache C:\_Dev Projects\VS Projects\bmccormack\CatalogPromotion\CatalogPromotionDll\bin \Debuggacutil /l CatalogPromotionDll Microsoft (R) .NET Global Assembly Cache Utility.

The Global Assembly Cache contains the following assemblies: CatalogPromotionDll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=9188a175 f199de4a, processorArchitecture=MSIL Number of items = 1 However, the assembly doesn't show up in C:\WINDOWS\assembly.

  • List of files and libraries that Window SDK contains?

    - by AKN
    For developing programs for windows, we need windows SDK. I understand that this SDK is what helps to create windows and handle window events and all that. I suppose it also enables us to manipulate with files and registries. (Does the same SDK is the reason for thread creation and handling?) All that is fine. I would like to know what are the files and libraries that come as a part of this SDK. Also does it come when I install the OS or when I install editors like Visual studio? Sometimes I see links to windows SDK separately as such. Is it same as the one that I get when installing Visual Studio or has something more than that.

  • IE to show Full URL path in the Title bar as in Status Bar

    - by Slavin
    Windows XP and IE8. Tabbed Browsing is OFF. So every single web page has its own title. I want to see in the title the same as I see in the Status bar i.e. I want the full URL of the web page I am viewing to be displayed in the Title bar, and so in the Task bar button too. How to achieve this? Thanks for all the answers in advance. Looks like this is rare case.

  • Low-level Keyboard Hooks/SendInput with Winkey+L possible? (workstation lockout is intercepted in Vi

    - by Brian Jorgensen
    I work on a project called UAWKS (Unofficial Apple Wireless Keyboard Support) that helps Windows users use Apple's bluetooth keyboard. One of the main goals of UAWKS is to swap the Cmd key (which behaves as Winkey in Windows) with Ctrl, allowing users to do Cmd+C for copy, Cmd+T for new tab, etc. It is currently developed using AutoHotkey, which worked pretty well under Windows XP. However, on Vista and Windows 7, Cmd+L causes problems: Regardless of low-level keyboard hooks, Winkey+L is always intercepted by Windows and normally locks the workstation... You can disable workstation locking with this registry hack, but pressing Winkey+L still can't be rebound in AHK Pressing Winkey+L leaves Winkey in the Keydown state until the next (additional) Winkey Up. Simulating a Keyup event doesn't seem to work either! It seems that Winkey+L is a special chord that messes everything else up. I've looked through the AHK source code, and they try to address this problem in SendKey() in keyboard_mouse.cpp (near line 883 in v1.0.48.05), but it doesn't work. I wrote up my own low-level keyboard hook application in C#, and I see the same problem. Has anyone else run into this? Is there a workaround?

  • Why Microsoft not provide for C# a static Win32 class with the most native functions and structures

    - by Oleg
    Everybody who used P/Invoke of Windows API knows a long list of declarations of static functions with attributes like [DllImport ("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)] The declaration of structures copied from Windows headers like WinNT.h or from web sites like www.pinvoke.net take also a lot of place in our programs. Why we all have to spend our time for this? Why Microsoft not give us a simple way to include a line like in old unmanaged programs #include <windows.h> and we would be have access to a static class Native with all or the most Windows functions and structures inside?

  • C++/Win32 : XP Visual Styles - no controls are showing up?

    - by mrl33t
    Okay, so i'm pretty new to C++ & the Windows API and i'm just writing a small application. I wanted my application to make use of visual styles in both XP, Vista and Windows 7 so I added this line to the top of my code: #pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"") It seemed to work perfectly on my Windows 7 machine and also Vista machine. But when I tried the application on XP the application wouldn't load any controls (e.g. buttons, labels etc.) - not even messageboxes would display. This image shows a small test application which i've just put together to demonstrate what i'm trying to explain: http://img704.imageshack.us/img704/2250/myapp.png In this test application i'm not using any particularly fancy or complicated code. I've effectively just taken the most basic sample code from the MSDN Library (http://msdn.microsoft.com/en-us/library/ff381409.aspx) and added a section to the WM_CREATE message to create a button: MyBtn = CreateWindow(L"Button", L"My Button", BS_PUSHBUTTON | WS_CHILD | WS_VISIBLE, 25, 25, 100, 30, hWnd, NULL, hInst, 0); But I just can't figure out what's going on and why its not working. Any ideas guys? Thank you in advanced. (By the way the application works in XP if i remove the manifest section from the top - obviously without visual styles though. I should also probably mention that the app was built using Visual C++ 2010 Express on a Windows 7 machine - if that makes a difference?)

  • Anything like VisualSVN Server for Mercurial?

    - by Billy ONeal
    VisualSVN server is a nice piece of software; particularly in that it uses the builtin Windows authentication mechanism on my server. I'd like to try to start using Mercurial though, and I'd like to keep the Windows authentication scheme. Is there some way to set this kind of thing up using the tools available on Windows Server 2008 R2 Standard (in particular, IIS 7)?

  • Will the other directories on my C drive still be visible?

    - by user225626
    My Windows 7 ate itself, corrupted a few files, now refuses to boot. On the same drive were other directories of various assorted non-Microsoft applications I like to use. After the crash, I have been mounting those from outside (as F:[whatever]). If I go ahead and reinstall Windows 7 on that drive and use the drive again as my primary, will those other directories be visible to it from inside? Meaning if I boot up my new installation of Windows from within that drive, will I be able to see those other old directories via Windows Explorer on the C drive (where any haven't been run over by the reinstalled OS)? Thanks for any help.

  • How to read tags out of m4a files in .NET?

    - by dkackman
    I've got some heavily modified code that ultimately came from the Windows Media SDK that works great for reading tags out of MP3 and WMV files. Somewhere along the line, Windows Media Player added support for .m4a files (was it in Windows 7?) but the Windows Media API doesn't seem to reflect that addition (or at least IWMMetadataEditor2::OpenEx pukes on an .m4a file). What would be some good C# code or links on how to dig meta data tags out of m4a files? (Google has come up dry on the C# front.) UPDATE AtomicParsley did indeed end being the best approach. Since that code is a command line tool however I ended up having to create a managed wrapper around some of its functionality in order to use in-process. It is posted on google code if anyone else needs such a thing.

  • win32 read java preference from c++ code

    - by Jayan
    One of our program writes program information(window title, memory etc) in Java Preferences. On windows this is available under registry. How can I read the values written by Java program using c (or c++). Looks like API I should use is RegGetValue. Is this guaranteed to work on Windows XP 32 bit? The String written by java is UTF-8 encoded. How do I read such strings in windows (win32 or vc++) Cheers, Jayan

  • Converting "User Shell Folders" registry value

    - by Sach
    The following registry key contains many system default folder locations. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders The value for the path of the All Users desktop, which is found there, is as follows: XP or earlier : [%ALLUSERSPROFILE%\Desktop] Vista or later: [%PUBLIC%\Desktop] Whereas the actual paths of the All User desktops, respectively, are as follows: XP or earlier : "C:\Documents and Settings\All Users\Desktop" Vista or later: "C:\Users\Public\Desktop" Now, if you use copy and paste the above registry values in Windows Explorer and hit enter it takes you to the actual folders. For example, if you paste [%PUBLIC%\Desktop] in a Windows Explorer in Vista it takes you to ["C:\Users\Public\Desktop"]. My question is this; how do I reproduce this behavior from withing a C# program? To be more specific, if I retrieve the registry value [%PUBLIC%\Desktop] from withing a C# program, which I can do easily, how do I convert it to ["C:\Users\Public\Desktop"]? Obviously I'm not looking for a string replacement, I need to do what Windows does.

  • Java - is this an idiom or pattern, behavior classes with no state

    - by Berlin Brown
    I am trying to incorporate more functional programming idioms into my java development. One pattern that I like the most and avoids side effects is building classes that have behavior but they don't necessarily have any state. The behavior is locked into the methods but they only act on the parameters passed in. The code below is code I am trying to avoid: public class BadObject { private Map<String, String> data = new HashMap<String, String>(); public BadObject() { data.put("data", "data"); } /** * Act on the data class. But this is bad because we can't * rely on the integrity of the object's state. */ public void execute() { data.get("data").toString(); } } The code below is nothing special but I am acting on the parameters and state is contained within that class. We still may run into issues with this class but that is an issue with the method and the state of the data, we can address issues in the routine as opposed to not trusting the entire object. Is this some form of idiom? Is this similar to any pattern that you use? public class SemiStatefulOOP { /** * Private class implies that I can access the members of the <code>Data</code> class * within the <code>SemiStatefulOOP</code> class and I can also access * the getData method from some other class. * * @see Test1 * */ class Data { protected int counter = 0; public int getData() { return counter; } public String toString() { return Integer.toString(counter); } } /** * Act on the data class. */ public void execute(final Data data) { data.counter++; } /** * Act on the data class. */ public void updateStateWithCallToService(final Data data) { data.counter++; } /** * Similar to CLOS (Common Lisp Object System) make instance. */ public Data makeInstance() { return new Data(); } } // End of Class // Issues with the code above: I wanted to declare the Data class private, but then I can't really reference it outside of the class: I can't override the SemiStateful class and access the private members. Usage: final SemiStatefulOOP someObject = new SemiStatefulOOP(); final SemiStatefulOOP.Data data = someObject.makeInstance(); someObject.execute(data); someObject.updateStateWithCallToService(data);

  • L-Soft LISTSERV TCPGUI Interface for PHP Creation

    - by poolnoodl
    I'm trying to use LISTSERV's "API" in PHP. L-Soft calls this TCPGUI, and essentially, you can request data like over Telnet. To do this, I'm using PHP's TCP socket functions. I've seen this done in other languages but can't quite convert it to PHP. I can connect, I can change set ASCII or BINARY mode. But I can never quite craft the header packet the way I need to authenticate, so I'm thinking I'm messing up my conversion. C: http://www.lsoft.com/manuals/16.0/htmlhelp/advanced%20topics/TCPGUI.html#2334328 $origin = '[email protected]'; $pwd = 'password'; $host = "example.com"; $port = 2306; $email = "[email protected]"; $list = "mailinglist"; $command = "Query $list FOR $email"; $fp = stream_socket_client("tcp://$host:$port", $errno, $errstr, 30); $cmd = $command . " PW=" . $pwd; $len = strlen($cmd); $orglen = strlen($origin); $n = $len + $orglen + 1; $headerPacket[0] = "1"; $headerPacket[1] = "B"; $headerPacket[2] = "\r"; $headerPacket[3] = "\n"; $headerPacket[4] = ord($n / 256); $headerPacket[5] = ord($n + 255); $headerPacket[6] = ord($orglen); for ($i = 0; $i < $orglen; $i++) { $headerPacket[$i + 7] = ord($origin[$i]); } for ($i = 0; $i < $len; $i++) { $cmdPacket[$i] = ord($cmd[$i]); } fwrite($fp, implode($headerPacket)); while (!feof($fp)) { echo fgets($fp, 1024); } Any thoughts on where I'm going wrong? I'd much appreciate it if anyone could point me toward some code to do this, days of googling and searching here on SO has only lead me to examples in other languages. Of course, if you know C (or Java or Perl as linked below in my comment to bypass the spam filter), PHP, and socket programming fairly well, you could probably rewrite the whole of the code in an hour, maybe a few minutes. You'd have my eternal thanks for that.

  • chdir programmatically

    - by james owen
    Friday, March 12, 2010 1:18 pm. In windows -- and probably unix for that matter -- using the chdir() function in a (32-bit) program doesn't change the directory when the program exits. (It does in a 16-bit windows program.) Does anybody know how to do that in a windows 32-bit program?

  • strange wpf errors on xp machine

    - by Yoav
    I created an application that has two windows. the second one is opened by .showDialog() command from the first window. on Windows 7 everything works fine but when running on XP the first window works fine but when trying to open the second window the application crash. exception message: Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception. and now for the weird part: when changing the application and making the second window run first it opens without a problem. when removing the icon from the second window (it's the same file for both windows) it also runs fine. any ideas on how to solve this?

  • International JRE6 or JDK6 or reading a file in "cp037" encoding scheme

    - by Reddy
    I have been trying to read a file in "cp037" encoding scheme using JAVA. I able to read a file in basic encoding schemes like UTF-8, UTF16 etc...After a bit of research on the internet i came to know that we need charset.jar or international version of JRE be installed to support extended encoding schemes. Can anyone send me a link for international version of JRE6 or JDK6. or is there any better way that i could read a file in cp037 encoding scheme. P.S: cp037 is a character encoding scheme supported by IBM Mainframes. All i need is to display a file in windows, which is being generated on IBM Mainframes machine, using a java program. Thanks in advance for your help... :-)

  • C++: How do I correctly register and unregister file type associations for our application (programa

    Time was when you set file associations in: HEY_CLASSES_ROOT\<.ext However, that seems to be possible, but an incomplete solution anymore. There are additional associations throughout the registry. For example: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\KindMap HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Extensions And all of the above, but by HKEY_USERS\ And Microsoft added their Set Default Associations control panel applet, which controls... what?

  • Why is glpk-java.jar not the same across all platforms?

    - by pruefsumme
    I'm using glpk-java in one of my projects. It provides a JNI to GLPK, a free LP/MIP solver. To use it under different platforms, you need different shared libraries (libglpk.so under Linux, libglpk.dylib under Mac OS X, glpk.dll under Windows) which is fully understandable. In addition, a java library is needed: glpk-java.jar. It's created as part of the build process. I was wondering why this JAR file (which only contains .class files) is different under different platforms? I.e., I cannot use the same glpk-java.jar under Linux and Mac OS X which means that I cannot put this file under revision control.

  • CRT, do we still need to redistribute it ?

    - by leeeroy
    Do we still need to bother with vcredist.exe when distributing windows native applications ? Does any of these come bundled with Win-7 ? If not, are there any technical reasons these are not shipped to people via e.g. windows update - insteadof letting us burden the customers with yet-another-thing-that.must-work ? (Ok, that might sound argumentative, but I'm really wondering the reason these libraries are not default installed/updated on windows machines)
