• sqlsrv_connect() not found..

  - by Gushiken

  Hey, I recently am working on an projekt that uses the "SQL Server Driver for PHP", i wanted to upgrade the existing driver to the new version (2.0), because I need some of the functions that have been implemented there. Now i replaced the old .dll in the php/ext directory and restarted the webserver. But now i recieve the following error: Fatal error: Call to undefined function sqlsrv_connect() in E:\ProjekteExtern\hades_apl\classes\sql\sqlsrv.class.php on line 34 But if i run phpinfo();, sqlsrv shows up, in the same way as the previous version did. Does anybody know this error or has an idea how to solve this problem? Thanks in advance :) Gushiken

• XML Architecture

  - by Roflcoptr

  For my application I have to use a undefined number of different detection strategies. A strategy is defined in the following fashion: The AND gate can also be a OR gate. For now, I hard coded all these rules in my code. For better extensability, I'd like to define all the detection startegies respectively rules in a XML file and parse it. But I'm not really sure how I can define such a detection strategy in a XML file. Any hints how to start?

• Dynamic loaded libraries and shared global symbols

  - by phlipsy

  Since I observed some strange behavior of global variables in my dynamically loaded libraries, I wrote the following test. At first we need a statically linked library: The header test.hpp #ifndef __BASE_HPP #define __BASE_HPP #include <iostream> class test { private: int value; public: test(int value) : value(value) { std::cout << "test::test(int) : value = " << value << std::endl; } ~test() { std::cout << "test::~test() : value = " << value << std::endl; } int get_value() const { return value; } void set_value(int new_value) { value = new_value; } }; extern test global_test; #endif // __BASE_HPP and the source test.cpp #include "base.hpp" test global_test = test(1); Then I wrote a dynamically loaded library: library.cpp #include "base.hpp" extern "C" { test* get_global_test() { return &global_test; } } and a client program loading this library: client.cpp #include <iostream> #include <dlfcn.h> #include "base.hpp" typedef test* get_global_test_t(); int main() { global_test.set_value(2); // global_test from libbase.a std::cout << "client: " << global_test.get_value() << std::endl; void* handle = dlopen("./liblibrary.so", RTLD_LAZY); if (handle == NULL) { std::cout << dlerror() << std::endl; return 1; } get_global_test_t* get_global_test = NULL; void* func = dlsym(handle, "get_global_test"); if (func == NULL) { std::cout << dlerror() << std::endl; return 1; } else get_global_test = reinterpret_cast<get_global_test_t*>(func); test* t = get_global_test(); // global_test from liblibrary.so std::cout << "liblibrary.so: " << t->get_value() << std::endl; std::cout << "client: " << global_test.get_value() << std::endl; dlclose(handle); return 0; } Now I compile the statically loaded library with g++ -Wall -g -c base.cpp ar rcs libbase.a base.o the dynamically loaded library g++ -Wall -g -fPIC -shared library.cpp libbase.a -o liblibrary.so and the client g++ -Wall -g -ldl client.cpp libbase.a -o client Now I observe: The client and the dynamically loaded library possess a different version of the variable global_test. But in my project I'm using cmake. The build script looks like this: CMAKE_MINIMUM_REQUIRED(VERSION 2.6) PROJECT(globaltest) ADD_LIBRARY(base STATIC base.cpp) ADD_LIBRARY(library MODULE library.cpp) TARGET_LINK_LIBRARIES(library base) ADD_EXECUTABLE(client client.cpp) TARGET_LINK_LIBRARIES(client base dl) analyzing the created makefiles I found that cmake builds the client with g++ -Wall -g -ldl -rdynamic client.cpp libbase.a -o client This ends up in a slightly different but fatal behavior: The global_test of the client and the dynamically loaded library are the same but will be destroyed two times at the end of the program. Am I using cmake in a wrong way? Is it possible that the client and the dynamically loaded library use the same global_test but without this double destruction problem?

• ubuntu server refusing connections via port forwarding

  - by Matt

  Getting some really weird behavior from our Ubuntu server... it's behind a Verizon router firewall with port forwarding (port 8080 to port 80 on the server), and we've been having issues accessing it via this external IP. From within the network, it appears to respond normally (I can access it via web browser and SSH), but refuses connections through port forwarding (using our static external IP). The strangest thing is that it actually responds to external port-forwarded connections right after being restarted, but quickly lapses back into this pattern of refusing external connections. I'm a bit of a server newbie (I'm actually a programmer in a small startup that just lost their server ops guy, urgh) so this is all trial by fire for me. Does anyone have any advice on what could be going wrong here? Any help would be appreciated, thanks.

• Attaching a function to the parent window from an iframe and getting proper scope

  - by Ronald

  I working on adding file uploading to my web application. I'm using an iframe to post my upload. When my php script processes the upload it writes some JavaScript to the iframe. This JavaScript is attempting to attach a function to the parent, this works, but when this function actually gets called it doesn't have the correct scope. Here is the code I'm attaching to the parent window: parent.window.showPreview = function(coords) { if (parseInt(coords.w) > 0) { var rx = 200 / coords.w; var ry = 250 / coords.h; $('#preview').css({ width: Math.round(rx * 400) + 'px', height: Math.round(ry * 533) + 'px', marginLeft: '-' + Math.round(rx * coords.x) + 'px', marginTop: '-' + Math.round(ry * coords.y) + 'px' }); } } When this function gets executed I get an error that says $ is not defined. I've tried adding changing the JQuery call to parent.$('#preview').css..., but then it says that parent is undefined. Any ideas?

• How to Tweet from multiple acounts with twitter Gem in Rails?

  - by Jmlevick

  I have an application wich has Oauth access using Twitter as provider. I also have the ability to ask the logged user permisson to Read and Write in his/her account and once a user authorized the app, I can send tweets as the user with something like: u = User.find(id) u.twitter.update("Some-Status-Here") in the rails console... What I want to do is to Tweet as all the users in one command, but if I try something like: u = User.all u.twitter.update("Some-Status-Here") I get this error: undefined method `twitter' for #<Array:0x00000002e2f188> How can I tweet as all the users in one command?

• How to quickly start Programs like "regedit.exe" from the Windows 7 search bar using substring matching?

  - by Palmin

  The search bar in Windows 7 is very convenient to quickly start applications by pressing the Win-key and then entering the name of the application. For applications with a Program Menu entry like Firefox, it is sufficient to type Fire and Firefox will be displayed in the Programs section of the search results. For other applications like regedit.exe, I have to type the full command regedit before the correct choice regedit.exe appears. Is there any way to have regedit.exe appear already when I have just entered a substring? Please note: I have seen Add my applications to Vista’s Start Search, but I don't want to add anything to the Start Menu manually. This question is about if there is some configuration that can be tuned to make the results appear. I have also seen Search behavior of Windows 7 start menu, but my problem is not that the exe appears under Files, regedit.exe correctly appears under Programs, but it should appear already for a substring match.

• Linux PHP web server horribly slow when accessed from any windows browser

  - by Ed Harcourt

  I have a Linux server (Ubuntu 10.04) running apache2 and PHP. Everything runs fine when accessing a page from any browser from another Linux machine or Mac. But when I try to access a page from any combination of Windows machine and browser I get about a 30 second delay before the page comes back. Accessing a plain old HTML file from the Windows browser runs lickity split. So it seems to be just PHP. MySQL is installed but a simple test page that uses no MySQL is still slow. I don't think it is DNS because if I hard code the IP address in the URL nothing changes. There doesn't seem to be anything in the log files that I can tell. What could be causing this behavior on Windows clients?

• printing double in binary

  - by Happy Mittal

  In Thinking in C++ by Bruce eckel, there is a program given to print a double value in binary.(Chapter 3, page no. 189) int main(int argc, char* argv[]) { if(argc != 2) { cout << "Must provide a number" << endl; exit(1); } double d = atof(argv[1]); unsigned char* cp = reinterpret_cast<unsigned char*>(&d); for(int i = sizeof(double); i > 0 ; i -= 2) { printBinary(cp[i-1]); printBinary(cp[i]); } } Here while printing cp[i] when i=8(assuming double is of 8 bytes), wouldn't it be undefined behaviour? I mean this code doesn't work as it doesn't print cp[0].

• NVidia raid 5 array spooling sounds and delay

  - by Chase B. Gale

  I've had a raid 5 array setup with 3 2TB WD Green drives for about 3 years now. Starting last week, when I would access the array for the first time, I hear a loud drive spooling sound and experience a ~5 second delay before being able to access\save files. This behavior happens when I don't use the array for some time (about an hour) and after occurring it doesn't happen again if I continue to access the array. I've run SMART scans on all drives and they come back as being a-ok. What's causing this? Is my array getting close to death?

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• Java - JPA - @Version annotation

  - by Yatendra Goel

  I am new to JPA. I am cofused about the @Version annotation. How it works? I have googled it and found various answers whose extract is as follows: JPA uses a version field in your entities to detect concurrent modifications to the same datastore record. When the JPA runtime detects an attempt to concurrently modify the same record, it throws an exception to the transaction attempting to commit last. But still I am not sure how it works? ================================================================================== Also as from the following lines: You should consider version fields immutable. Changing the field value has undefined results. Does it mean that we should declare our version field as final

• Why does Outlook 2010 give the message "Creating a new item from the selected items could take some time...are you sure you create a new item...?

  - by Matt

  I'm using Outlook 2010 with Exchange 2007. I am moving emails from my Deleted Items folder to a user-created folder. When I move a "low" number of messages, say a few hundred or less, the operation completes successfully. When I move a "large" number of messages (in this example it's over 800) I get the message shown in the screenshot below. If I click Yes, a new email is generated and has links to all the emails I selected in the Attachment field. When I cancel that email, not only have the messages not moved but they appear to be deleted entirely. What does the message mean and why does it get presented? Why does clicking Yes do the behavior I described above?

• PuTTY: how to properly emulate -t option

  - by John Sonderson

  On Linux the ssh command has a -t option whose man page reads: Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocate, even if ssh has no local tty. I would like to use this same option with PuTTY on Windows. In particular, I can see that PuTTY has a bunch of options under: Category - Connection - SSH - TTY and suspect it might be possible to achieve the same behavior via some of the (NUMEROUS!) settings found on this screen. Anyone know how to configure the following command: ssh -t USER,[email protected] create Thanks!

• Conditional value for ActiveRecord create method only

  - by Steve Wright

  I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

• OS X SnowLeopard menubar icons appear/disappear in 8 second cycle

  - by Robot

  I just bought a new Mac Mini, and used Migration Assistant to move a user from an iMac to it. All went well, except a very strange behavior... the default OS X menubar icons like time, spotlight, etc (but NOT user installed app icons like dropbox or xmarks) appear and disappear in a very regular 8 second cycle. They appear for about 2 seconds, and then disappear for about 6. This is a screenshot with the icons, and this is a screenshot without them. This is very annoying and I have not found anything online with similar symptoms. Any ideas?

• Dry length of buoy in OrcaFlex

  - by KAE

  I use a software package called OrcaFlex to model the behavior of a buoy in ocean waves. I would like to share OrcaFlex questions in this forum - hope some users are out there! Here is a starter question: For a 6D buoy, I extracted the 'Dry Length' after the simulation completed. The value of the Dry Length sometimes slightly exceeds the actual height of the buoy, even though this would not seem to be possible given the formula from the manual, Dry Length = (cylinder length) × (cylinder volume above surface) / (cylinder total volume). Any insights?

• Uploading to YouTube makes all browser tabs and devices disconnect

  - by fabsenet

  Whenever I upload a video to YouTube all other browser tabs behave like there is no connection at all. It even affects my phone and other computers on the network therefor I think it has to do with my router. When the upload is done everything works normally again. I never observed this behavior with any other upload. My router is a Fritz!Box 7390 and my uploading PC is connected through a 1000mb/s switch (wired) to the router. Uploading through another browser does not change anything. I understand that other sites become slow as the network resources are limited, but stopping altogether feels wrong. speed.io measures for my internet connection: 40.894 Kbit/s down, 2.685 Kbit/s up, 29 ms ping, 2.048 con/m connects

• php-cgi got SIGKILL on burst.net VPS?

  - by Shawn

  I got an VPS at burst.net, very cheap one, but this doesn't matter. The strange behavior of it is, the php-cgi process, which started using lighthttpd's spawn-cgi, dies every a few minutes. however, other processes are fine and great, even include a java process, and I'm sure there is no "out of memory" issue, so it's not killed by OOM killer. I used strace to trace the process, and found out it was killed by SIGKILL, hence no single log was left on the disk, just dies suddenly. Is there anyway I can find out what process/thing sent the SIGKILL to the poor php process? Filed a ticket with the vendor, but they said they won't care. strace -p 7176 Process 7176 attached - interrupt to quit wait4(-1, <unfinished ...> +++ killed by SIGKILL +++
