  • when do we have a virtual memory problem using Fastmm4?

    - by JD
    Hi, We have an application whose virtual memory rises and keep going for over a day. After two days it has climbed to about 500MB. I have tried profiling the applications which hits a database as well as makes lots of http and soap requests but I Fastmm4 shows there are no leaks. I am not sure how or when memory is claimed and if there is a problem here with the rising virtual memory? JD

  • I cannot connect to database from Drupal

    - by Patrick
    hi, I've uploaded my drupal website (and related database) to my new server. The database info is: host: localhost user: user pass: pass databaseName = database_name I've set the following line in settings.php file: $db_url = 'mysqli://user:password@localhost/database_name'; but what I get is this: If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider. I guess the database is running, it always run and I can access with phpmyadmin so I think the problem is not there. The database and website files upload have also been succesfull.. so I dunno what to do to fix this issue. It is mysql on IIS Server thanks

  • Can't find instructions how to use Windows 7 drivers on Windows Server 2008 R2

    - by Robert Koritnik
    Maybe I should post this to http://www.serverfault.com. Windows 7 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 doesn't event though it's practically the same OS when it comes to drivers. But I know that this has a very good reason. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are normally desktop machines and would need Windows 7 driver spectrum... Question I know I've been reading about some trick on the internet that first installed Windows 7 on the machine, than do something to get either all Windows 7 driver collection or just those installed, and then install Windows Server 2008 and use those drivers. The thing is: I can't seem to find these instructions on the internet any more. If anybody knows where these are please provide the link for the rest of us.

    - by ahsteele
    I have Bluetooth installed in my laptop. The Bluetooth is enabled according to the status light. However, I do not see Bluetooth listed in device manager or have a control panel option for it. A scan for new hardware doesn't turn up Bluetooth. Nor are any devices listed with a Yellow Exclamation Point. I do have three USB Hubs Listed as "Generic USB Hub." There is no Bluetooth icon in the notification area and Bluetooth is not listed under Devices and Printers. What am I missing?

  • What is the accepted pattern for WPF commanding in MVVM?

    - by Robert S.
    I'm working on a WPF app and I understand the command pattern pretty well, but I've found that there are several different implementations of the command pattern for MVVM. There's Josh Smith's implementation in his WPF sample app, the DelegateCommand from Prism, and the CommandBindings implementation. My question is, what is the generally accepted best practice for using commands with MVVM? My application uses Prism so DelegateCommand is available to us. The devs on my team are arguing about which approach is "best." Some don't like the numerous .cs files generated for each command, others prefer that everything be wired up via CommandBindings. I'm at a loss. Can anyone shed some light?

  • How can I give a color to imagecolorallocate?

    - by Roman
    I have a PHP variable which contains information about color. For example $text_color = "ff90f3". Now I want to give this color to imagecolorallocate. The imagecolorallocate works like that: imagecolorallocate($im, 0xFF, 0xFF, 0xFF); So, I am trying to do the following: $r_bg = bin2hex("0x".substr($text_color,0,2)); $g_bg = bin2hex("0x".substr($text_color,2,2)); $b_bg = bin2hex("0x".substr($text_color,4,2)); $bg_col = imagecolorallocate($image, $r_bg, $g_bg, $b_bg); It does not work. Why? I try it also without bin2hex, it also did not work. Can anybody help me with that?

  • Compiling gstreamer plugin in windows

    - by utnapistim
    Hello all, My question: What is the correct way to compile a gstreamer plugin in windows, so that it will be accepted by gstreamer (actually Songbird on top of gstreamer). My setup: I have downloaded the songbird sources following the steps described here and I have a trunk/dependencies/windows-i686-msvc8 directory within my svn sources with all the gstreamer binaries. I have created a gstreamer empty plugin skeleton following the steps detailed in the GStreamer Plugin Writer's Guide, and compiled it against the gstreamer binaries in the Songbird dependencies folder. The compilation was done with VS2010 RC1 (Visual Studio 2008 yelded the same results), using an empty DLL project with the .h and .c files generated using the GStreamer Plugin Writer's Guide. The DLL was lined with libcpmt.lib, libcmt.lib, ws2_32.lib, gobject-2.0.lib, gthread-2.0.lib, gstreamer-0.10-0.lib, glib-2.0.lib, kernel32.lib, nspr4.lib and ignoring all default libraries. I have compiled the files as both .c and .cpp with the same results. Testing: I have installed the Songbird binaries corresponding to the correct svn version, then installed Songbird Developer Tools addon and used it to create an addon for testing my gstreamer plugin. Songbird will not load the pluggin. I have also tried to load it with gst-launch.exe from the trunk/dependencies/windows-i686-msvc8/[...] directory and that generated runtime error R6034: An application has made an attempt to load the C runtime library incorrectly. Most resources I found for this problem recommended restarting or reinstalling windows :(.

  • Finding efficient overlapped entries in a SQL table

    - by Laoneo
    What is the most efficient way to find all entries which do overlap with others in the same table? Every entry has a start and end date. For example I have the following database setup: CREATE TABLE DEMO ( DEMO_ID int IDENTITY , START date NOT NULL , END date NOT NULL }; INSERT INTO DEMO (DEMO_ID, START, END) VALUES (1, '20100201', '20100205'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (2, '20100202', '20100204'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (3, '20100204', '20100208'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (4, '20100206', '20100211'); My query looks as follow: SELECT DISTINCT * FROM DEMO A, DEMO B WHERE A.DEMO_ID != B.DEMO_ID AND A.START < B.END AND B.START < A.END The problem is when my demo table has for example 20'000 rows the query takes too long. My environment is MS SQL Server 2008. Thanks for any more efficient solution

  • Disable AND Grey out an eclipse widget

    - by Fredrik
    I have a org.eclipse.swt.widgets.Composite that I want to be able to enable/disable programatically. The org.eclipse.swt.widgets.Control.setEnabled(boolean enabled) method works fine, but it does not give any visual information that the widget(s) are disabled. What I would like to do is to have the disabled state mean the widgets are greyed out. Right now they just enter a weird state where the user is unable to click or perform any action on them.

  • Is it rude to add "TODO: wtf?" in source code?

    - by mafutrct
    I encountered something ... well, you know TDWTF... something like that in an international project I'm working on. The code was written by a team mate. For a second I was tempted to add // TODO: wtf? to the infringing code but restrained myself. The project is indeed on a professional level, but for internal conversation, more colloquial language is used - but still no "bad" words as in "wtf". Usually, I'd surely not add such a comment, but I believe there are a few factors that allow consideration still: 1. It is not visible except as a comment in the source code (of course). 2. It is internal to our team - other developers may happen see it but it is not their code. 3. Comments in source code are usually accepted to be more colloquial, since it is "kept between us developers". Would you totally advise to never add such a comment? Or do you regard it as an edge case? Did you possibly add something similar yourself?

  • Confused about Android API's and compatability

    - by Keith
    I have purchased an HTC Incredible and have dived into the world of android! Only to find myself totally confused about the API levels and backward compatibility. My device runs the 2.1 OS, but I know that most of the devices out there run 1.5 or 1.6; and soon the 2.2 OS will be running on new devices. The SDK has gone through such enormous changes, that even constants have been renamed (from VIEW_ACTION to ACTION_VIEW for example). Methods have been added and removed (onPause replacing the earlier call, etc al). So, If I want to write an application that will work from 1.6+, does that mean I have to install and write my code using the 1.6 API; then test on later versions? Or can I write using the 2.1 SDK and just set the minSDK level and not use "new" features? I have never worked with an SDK that changes SO drastically from release to release! So I am not sure what to do.... I read through an article on the Android Development site(and this posting on stack overflow that references it: http://stackoverflow.com/questions/2076150/should-a-legacy-android-application-be-rebuilt-using-sdk-2-1), but it was still not very clear to me. Any help would be appreciated

  • How to parse a string to an integer without library functions?

    - by dack
    Hi, I was recently asked this question in an interview: "How could you parse a string of the form '12345' into its integer representation 12345 without using any library functions, and regardless of language?" I thought of two answers, but the interviewer said there was a third. Here are my two solutions: Solution 1: Keep a dictionary which maps '1' = 1, '2' = 2, etc. Then parse the string one character at a time, look up the character in your dictionary, and multiply by place value. Sum the results. Solution 2: Parse the string one character at a time and subtract '0' from each character. This will give you '1' - '0' = 0x1, '2' - '0' = 0x2, etc. Again, multiply by place value and sum the results. Can anyone think of what a third solution might be? Thanks.

  • Calling a generic function in VB.NET / C#

    - by Quandary
    Question: I want to call a generic function, defined as: Public Shared Function DeserializeFromXML(Of T)(Optional ByRef strFileNameAndPath As String = Nothing) As T Now when I call it, I wanted to do it with any of the variants below: Dim x As New XMLserialization.cConfiguration x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of x)() x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(GetType(x))() x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of GetType(x))() But it doesn't work. I find it very annoying and unreadable having to type x = XMLserialization.XMLserializeLDAPconfig.DeserializeFromXML(Of XMLserialization.cConfiguration)() Is there a way to call a generic function by getting the type from the instance ?

  • Performing an action on Parent/Child elements independently.

    - by Matt Weldon
    I have HTML similar to the following in my page <div id="someDiv"> <img src="foo.gif" class="someImg" /> </div> The wrapper div is set up such that when it is clicked, it's background-color changes using the following jQuery code. $("div").click(function(event){ $(this).css("background-color", "blue"); }); I also have some jQuery associated with my img that will do some other function (for the sake of argument I am going to display and alert box) like so: $("img[class=someImg]").click(function(event){ alert("Image clicked"); }); The issue I have come across is that when I click on the img, the event associated with the div is also triggered. I'm pretty sure that this is due to the way that jQuery (or indeed JavaScript) is handling the two DOM elements - clicking the img would require you to also technically click the div, thus triggering both events. Two questions then really: Is my understanding of the DOM/JavaScript flawed in some way or is this actually how things are occurring? Are there any jQuery methods that would allow me to perform actions on a child element without invoking those associated with its parent?

  • running a python script on a remote computer

    Hello all, I have a python script and am wondering is there any way that I can ensure that the script run's continuously on a remote computer? Like for example, if the script crashes for whatever reason, is there a way to start it up automatically instead of having to remote desktop. Are there any other factors I have to be aware of? The script will be running on a window's machine.
