• How to parse a Zend URL for parameters?

  - by wizzard

  I am trying to extract the GET parameters from a ZF REST URL. It's not the current request and I don't want to call the URL or execute the route, I just need the parameters. I'm looking for a utility function like parse_url(), but for the Zend REST format. Is there one, or do I have to reinvent the wheel? I've tried a few things like creating a new Zend_Controller_Request_Http but the parameters aren't being populated. It is a valid HTTP URL. Edit: Upon request, a sample Zend URL: http://localhost/index/index/param1/foo/param2/bar So I am just trying to get param1 and param2 out of this URL.

• JavaScript - checking for any lowercase letters in a string

  - by pcampbell

  Consider a JavaScript method that needs to check whether a given string is in all uppercase letters. The input strings are people's names. The current algorithm is to check for any lowercase letters. var check1 = "Jack Spratt"; var check2 = "BARBARA FOO-BAR"; var check3 = "JASON D'WIDGET"; var isUpper1 = HasLowercaseCharacters(check1); var isUpper2 = HasLowercaseCharacters(check2); var isUpper3 = HasLowercaseCharacters(check3); function HasLowercaseCharacters(string input) { //pattern for finding whether any lowercase alpha characters exist var allLowercase; return allLowercase.test(input); } Is a regex the best way to go here? What pattern would you use to determine whether a string has any lower case alpha characters?

• How can you set a time limit for a PowerShell script to run for?

  - by calrain

  I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropriate as I am calling an external code library that can just hang for a long time. I want to limit a block of code and only allow it to run for x seconds, after which I will terminate that code block and return a response to the user that the script timed out. I have looked at background jobs but they operate in a different thread so won't have kill rights over the parent thread. Has anyone dealt with this or have a solution? Thanks!

• OpenGL ES displaying HUD display Text can't be colored black on top of textured 3D objects

  - by ivanceras

  This is a follow-up of this question on here http://iphonedevelopment.blogspot.com/2010/02/drawing-hud-display-in-opengl-es.html It tackles on the HUD (heads up display) which is based on this tutorial http://stackoverflow.com/questions/2681102/opengl-es-displaying-hud-display-has-no-color-on-top-of-textured-3d-objects I wanted to set the "Text" in color BLACK, but it is more complicated than what I thought. Setting it to some other color other than black "glColor4f(0.0, 0.0, 0.0, 1.0);" is just fine. I assume that the culprit must be in the Blending function "glBlendFunc (GL_ONE, GL_ONE);" I experimented a lot of combinations with no luck. Has anyone experimented on this one on top of textured 3D in the backgrounds working?

• Convert 12hour time to 24Hour time

  - by RwardBound

  I have hourly weather data. I've seen the function examples from here: http://casoilresource.lawr.ucdavis.edu/drupal/node/991 I'm altering the code to account for airport data, which has a different URL type. Another issue with the airport weather data is that the time data is saved in 12 hour format. Here is a sample of the data: 14 10:43 AM 15 10:54 AM 16 11:54 AM 17 12:07 PM 18 12:15 PM 19 12:54 PM 20 1:54 PM 21 2:54 PM Here's what I attempted: (I see that using just 'PM' isn't careful enough because any times between 12 and 1 pm will be off if they go through this alg) date<-Sys.Date() data$TimeEST<-strsplit(data$TimeEST, ' ') for (x in 1:35){ if('AM' %in% data$TimeEST[[x]]){ gsub('AM','',data$TimeEST[[x]]) data$TimeEST[[x]]<-str_trim(data$TimeEST[[x]]) data$TimeEST[[x]]<-str_c(date,' ',data$TimeEST[x],':',data$TimeEST[2]) } else if('PM' %in% data$TimeEST[[x]]){ data$TimeEST[[x]]<-gsub('PM', '',data$TimeEST[[x]]) data$TimeEST[[x]]<-strsplit(data$TimeEST[[x]], ':') data$TimeEST[[x]][[1]][1]<-as.integer(data$TimeEST[[x]][[1]][1])+12 data$TimeEST[[x]]<-str_trim(data$TimeEST[[x]][[1]]) data$TimeEST[[x]]<-str_c(date, " ", data$TimeEST[[x]][1],':',data$TimeEST[[x]][2]) } } Any help?

• Hiding/Unhiding Control in Gridview’s column - shifting problem

  - by lupital

  This is a follow up to my previous question: link text In gridview's column i have a linkbutton and a label under it. I want to hide/unhide label when linkbutton is clicked. I use javascript because i don't want any postbacks. The code: protected void gvwComments_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { LinkButton lButton = ((LinkButton)e.Row.Cells[2].FindControl("lbtnExpand")); Label label = ((Label)e.Row.Cells[2].FindControl("lblBody")); lButton.Attributes.Add("onclick", string.Format("HideLabel('{0}'); return false;", label.ClientID)); } } function HideLabel(button) { var rowObj = document.getElementById(button); if (rowObj.style.display == "none") { rowObj.style.display = "block"; } else { rowObj.style.display = "none"; } } The problem is that when I unhide the label by clicking on button, linkbutton is shifted a a bit upper it's original position in the cell. Is it possible to preserve linkbutton's position in the gridviews cell?

• C++ word to bytes

  - by Vit

  Hi, I tried to read CPUID using assembler in C++. I know there is function for it in , but I want the asm way. So, after CPUID is executed, it should fill eax,ebx,ecx registers with ASCII coded string. But my problem is, since I can in asm adress only full, or half eax register, how to break that 32 bits into 4 bytes. I used this: #include <iostream> #include <stdlib.h> int main() { _asm { cpuid /*There I need to mov values from eax,ebx and ecx to some propriate variables*/ } system("PAUSE"); return(0); }

• Can I Always debug multiple instances of a same object that is of type thread with GDB?

  - by yan bellavance

  program runs fine. When I put a breakpoint a segmentation fault is generated. Is it me or GDB? At run time this never happens and if I instantiate only one object then no problems. Im using QtCreator on ubuntu x86_64 karmic koala. UPDATE1: I have made a small program containing a simplified version of that class. You can download it at: example program simply put a breakpoint on the first line of the function called drawChart() and step into to see the segfault happen UPDATE2: This is another small program but it is practically the same as the mandlebrot example and it is still happening. You can diff it with mandlebrot to see the small difference. almost the same as mandlebrot example program

• How to get SQL Server Date in its native format?

  - by RoguePlanetoid

  I need to get a Date from an SQL Server Database (SQL Server 2000), the date is stored as such: 2009-09-30 00:00:00.000 I want to pass this date into a Classic ASP function to use this date in the Database somewhere else, however when I get the date, it converts in my ASP code to a locale-dependant version, such as: 30/09/2009 I just want the date as-is as formatting the date so it is correct again seems unnecessary, although if this the only way then fine - is there any way to treat it as string data so it stays like that, so it can be inserted back into the database as the same date, without needing conversion?

• How to model dependency injection in UML ?

  - by hjo1620

  I have a Contract class. The contract is valid 1 Jan 2010 - 31 Dec 2010. It can be in state Active or Passive, depending on which date I ask the instance for it's state. ex. if I ask 4 July 2010, it's in state Active, but if I ask 1 Jan 2011, it's in state Passive. Instances are created using constructor dependency injection, i.e. they are either Active or Passive already when created, null is not allowed as a parameter for the internal state member. One initial/created vertex is drawn in UML. I have two arrows, leading out from the initial vertex, one leading to state Active and the other to state Passive. Is this a correct representation of dependency injection in UML ? This is related to http://stackoverflow.com/questions/2779922/how-model-statemachine-when-state-is-dependent-on-a-function which initiated the question on how to model DI in general, in UML.

• How to cause bindings to be updated, particularly for derived values?

  - by rrhartjr

  I'm using some CLR objects that use the INotifyPropertyChanged interface and use the PropertyChanged function to update in WPF bindings. Pretty boilerplate: protected void RaisePropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } Then the property: private double m_TotalWidgets = 0; public double TotalWidgets { get { return m_TotalWidgets; } set { m_TotalWidgets = value; RaisePropertyChanged("TotalWidgets"); } } Is there a better way to update a derived value or even the whole class? Say I had a calculated value: public double ScaledWidgets { get { return TotalWidgets * CONSTANT_FACTOR; } } I would have to fire ScaledWidget's PropertyChanged when TotalWidgets is updated, eg: set { m_TotalWidgets = value; RaisePropertyChanged("TotalWidgets"); RaisePropertyChanged("ScaledWidgets"); } Is there a better way to do this? Is it possible "invalidate" the whole object, especially if there are a lot of derived values? I think it would be kind of lame to fire 100 PropertyChanged events.

• How, exactly, does the double-stringize trick work?

  - by Peter Hosey

  At least some C preprocessors let you stringize the value of a macro, rather than its name, by passing it through one function-like macro to another that stringizes it: #define STR1(x) #x #define STR2(x) STR1(x) #define THE_ANSWER 42 #define THE_ANSWER_STR STR2(THE_ANSWER) /* "42" */ Example use cases here. This does work, at least in GCC and Clang (both with -std=c99), but I'm not sure how it works in C-standard terms. Is this behavior guaranteed by C99? If so, how does C99 guarantee it? If not, at what point does the behavior go from C-defined to GCC-defined?

• Using JQuery to get text of a div that's a child of a header to replace a different header

  - by Stevie Jenowski

  Hello all, I'm trying to get the text contents of a .div('.child#') child of my event.target('h6.class'), and replace my other headers('h1.replacHeader#') using this script below... $('h6.class').click(function(event) { var $target = $(event.target); $('.replaceHeader1').replaceWith("<h1 class='replaceHeader1'>" + $target.children(".child1").text() + "</h1>"); $('.replaceHeader2').replaceWith("<h1 class='replaceHeader2'>" + $target.children(".child2").text() + "</h1>"); }); }); I've noticed that .text() apparently doesn't apply to an event.target... So how could I go about achieving this?

• How to create proc under /proc/driver?

  - by Mustika_wiguna

  I want to create a proc file under /proc/driver directory. I would like to use a macro like proc_root_driver (or something else provided) rather than use "driver/MODULE_NAME" explicitly. I use create_proc_entry : ... struct proc_dir_entry *simpleproc_fops_entry; simpleproc_fops_entry = create_proc_entry(MODULE_NAME, 0400, NULL /* proc_root_dir */); ... After googling, I found suggestion to use proc_root_driver, but when I use it, error "proc_root_driver undeclared in this function". And also, proc_root_driver is not available in linux/proc_fs.h. I have tried to declare structure like this: struct proc_dir_entry proc_root; struct proc_dir_entry *proc_root_driver = &proc_root; Errors gone, but proc file didn't exist under /proc/driver or /proc Anyone here can help me? Thanks in advances.

• converting an array of characters to a const gchar*

  - by Mark Roberts

  I've got an array of characters which contains a string: char buf[MAXBUFLEN]; buf[0] = 'f'; buf[1] = 'o'; buf[2] = 'o'; buf[3] = '\0'; I'm looking to pass this string as an argument to the gtk_text_buffer_insert function in order to insert it into a GtkTextBuffer. What I can't figure out is how to convert it to a const gchar *, which is what gtk_text_buffer_insert expects as its third argument. Can anybody help me out?

• TSQL Check Database Instance Online

  - by David in Dakota

  What is the best way to check if an instance of Microsoft SQL Server is up? I have a view that spans two instances of Microsoft SQL Server but before querying it in a stored procedure I would like to verify that the second instance of the server is up with a fallback option of just querying local data. The second instance is a linked server. Currently I'm considering a SQL CLR function that can attempt to open a connection with a shorter timeout but I'm wondering if it's something that can be done directly in Transact SQL.

• Passing a JavaScript variable to a helper method

  - by Brendan Vogt

  I am using ASP.NET MVC 3 and the YUI library. I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such: window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))'; Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like: var formatActionLinks = function (oCell, oRecord, oColumn, oData) { var newsId = oRecord.getData('NewsId'); oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>'; };

• Javascript parent page redirection from iframe.

  - by Danil

  Hello to all. I need to implement parent page redirection from iframe. I know that it is impossible to do in different domains due to browsers security. However I found that links have target attribute and tried to use it in the following way: <a href="http://google.com" target="_top" id="testParentRedirect">someLink</a> It works fine if I click this link manually, but I couldn't find cross-browser solution to simulate it using javascript. document.getElementById('testParentRedirect').click(); This works fine in IE, however Firefox and Safary don't know click function :). I tried to work with jquery, but for some reason they don't simulate click event for links. (see following post) I couldn't find any appropriate solution on stackoverflow. Maybe someone could help me in it. I will appreciate it. :)

• Perl latin-9? Unicode - need to add support

  - by Phill Pafford

  I have an application that is being expanded to the UK and I will need to add support for Latin-9 Unicode. I have done some Googling but found nothing solid as to what is involved in the process. Any tips? Here is some code (Just the bits for Unicode stuff) use Unicode::String qw(utf8 latin1 utf16); # How to call $encoded_txt = $self->unicode_encode($item->{value}); # Function part sub unicode_encode { shift() if ref($_[0]); my $toencode = shift(); return undef unless defined($toencode); Unicode::String->stringify_as("utf8"); my $unicode_str = Unicode::String->new(); # encode Perl UTF-8 string into latin1 Unicode::String # - currently only Basic Latin and Latin 1 Supplement # are supported here due to issues with Unicode::String . $unicode_str->latin1( $toencode ); ... Any help would be great and thanks.

• Java: InitialContext.lookup(String) - what should the value o the parametr be?

  - by bguiz

  To instantiate a Stateful Session Bean inside of a JSP/ servlet, I am using: InitialContext ic = new InitialContext(); SomeStateful state = (SomeStateful) ic.lookup("java:comp/env/SomeStatefulBean"); Trial and error had me prefix the name of my EJB with java:comp/env/, so the above works (on Glassfish 2.1). However I want to know what the proper way to obtain this prefix is. Is there a CLI tool or function somewhere in the admin panel that will allow we to examine/ alter this? Is this platform/ application server dependant? Is there a setting within my ear, EJB-jar or war which I can examine or alter for this? (Forgive the beginner question) Thanks!

• Copying a 14bit grayscale image (saved in long[]) to a pictureBox

  - by Itsik

  My camera gives me 14bit grayscale images, but the API's function returns a long* to the image data. (so i'm assuming 4 bytes for each pixel) My application is written in C++/CLI, and the pictureBox is of .NET type. I am currently using the BitmapData.LockBits() mechanism to gain pointer access to the image data, and using memcpy(bmpData.Scan0.ToPointer(), imageData, sizeof(long)*height*width) to copy the image data to the Bitmap. For now, the only PixelFormat that is working is 32bit RGB, and the image appears in shades of blue with contours. Trying to initialize the Bitmap as 16bppGrayscale isn't working. I would ideally want to cast the array from long to word and using a 16bit format (hoping the the 14bit data will be displayed properly) but I'm not sure if this works. Also, I don't want to iterate over the image data, so finding the min/max and then histogram stretching to [0..255] isnt an option for me (the display must be as efficient as possible) Thanks

• Where is the bottleneck in this code?

  I have the following tight loop that makes up the serial bottle neck of my code. Ideally I would parallelize the function that calls this but that is not possible. //n is about 60 for (int k = 0;k < n;k++) { double fone = z[k*n+i+1]; double fzer = z[k*n+i]; z[k*n+i+1]= s*fzer+c*fone; z[k*n+i] = c*fzer-s*fone; } Are there any optimizations that can be made such as vectorization or some evil inline that can help this code? I am looking into finding eigen solutions of tridiagonal matrices. http://www.cimat.mx/~posada/OptDoglegGraph/DocLogisticDogleg/projects/adjustedrecipes/tqli.cpp.html
