  • jQuery slider vanishes after container div is toggled

    - by Shahar Evron
    I have a page which contains a jQuery-UI horizontal slider, created using a little function, inside a DIV which can be displayed / hidden by clicking on it's title, using $.toggle(). Problem is, once the div is hidden, when it is expanded the slider is gone. A simplified demo of the problem can be seen here: http://arr.gr/jquery-issue.html (file contains all relevant source code) - when clicking the "Advanced Options" title to hide and then show the div, the slider is no longer there. Any suggestions on how to work around this?

  • Authorize.net Payment integration

    - by Click Upvote
    I'm looking to do Authorize.net payment integration with a website using PHP. My questions are: 1) Where I can find a tutorial, development guide, and/or code samples for doing this with PHP. 2) Is it possible to obtain a test account to do the integration like Paypal's sandbox, or does one need to have a live account to which you can pass an additional parameter to indicate the transaction is a test one? All other advice will also be helpful. Thanks!

  • find window text and save txt to file named that wont work.

    - by blood
    hi, my code wont work and idk why. the point of my code is to find the top window and save a text file with the name the same as the text on the top menu bar (task bar i think?). then save some data to that text file. but everytime i try to use it the write fails if i set the name of the text file before hand so it wont change it will write the data to the file. but if i don't set it before hand it will make the text doc but not write anything to it. or sometimes it will just write numbers for the name (i think it's the handle number) then it will write the data. :\ it's odd can anyone help? #include <iostream> #include <windows.h> #include <fstream> #include <string> #include <sstream> #include <time.h> using namespace std; string header_str = ("NULL"); #define DTTMFMT "%Y-%m-%d %H:%M:%S " #define DTTMSZ 21 char buff[DTTMSZ]; fstream filestr; string ff = ("C:\\System logs\\txst.txt"); TCHAR buf[255]; int main() { GetWindowText(GetForegroundWindow(), buf, 255); stringstream header(stringstream::in | stringstream::out); header.flush(); header << ("C:\\System logs\\"); header << buf; header << (".txt"); header_str = header.str(); ff = header_str; cout << header_str << "\n"; filestr.open (ff.c_str(), fstream::in | fstream::out | fstream::app | ios_base::binary | ios_base::out); filestr << "dfg"; filestr.close(); Sleep(10000); return 0; }

  • Accessing Content Page elements

    - by Abdel Olakara
    Hi all, I am facing a strange problem.. may be i am overlooking something and not able to find the silly issue. Need your help! I have a Master page and a Content Page: <form id="AccountForm" runat="server"> <div> <asp:ContentPlaceHolder ID="MenuHolder" runat="server"> </asp:ContentPlaceHolder> </div> <hr /> <div> <asp:ContentPlaceHolder ID="ContentHolder" runat="server"> </asp:ContentPlaceHolder> </div> And my content page has some form elements: <asp:Content ID="Content3" ContentPlaceHolderID="ContentHolder" runat="server"> First Name: <asp:TextBox ID="fName" runat="server"></asp:TextBox> <br /> Middle Name: <asp:TextBox ID="mName" runat="server"></asp:TextBox> <br /> Family Name: <asp:TextBox ID="lName" runat="server"></asp:TextBox> <br /> Birthday: <asp:TextBox ID="birthday" runat="server"></asp:TextBox> <br /> Mobile Phone: <asp:TextBox ID="mobile" runat="server"></asp:TextBox> <br /> Alternate Phone: <asp:TextBox ID="phone" runat="server"></asp:TextBox> <br /> I also have the code for submit button in the content page where i try to retrieve the values from the form elements and persist it into DB. Here is the SubmitButton_Click code: protected void SubmitButton_Click(object sender, EventArgs e) { log.Info("From Submit button: " + customerObject.first_name + " " + customerObject.family_name); if (fName != null) log.Info("First Name is not null"); log.Info("First Name:" + fName.Text); log.Info("Middle Name:" + mName.Text); log.Info("Family Name:" + fName.Text); log.Info("Mobile:" + mobile.Text); log.Info("Phone: " + phone.Text); log.Info("Address:" + bAddressL1.Text + bAddressL2.Text); Strangly.. i don't get any data that is filled into my text fields? Their objects are not null as well!! why is this behaviour happening? I am not trying to access elements in master page or other.. all the fields are in the content page.. only thing is there is no form element in the content page and the form element is in master page! Thanks in advance for your suggestions and answers. Abdel Raoof Olakara

  • WPF: ContextMenu item bound to a Command is enabled only after invoking the command from another so

    - by Brad
    I have a ContextMenu whose items are all bound to commands and enable\disable correctly after ANY Command is invoked from another source but prior to, they are all disabled. So if I run the app, all the MenuItems are disabled but if I invoke any of the bound commands from another source (buttons, for instance) they become synchronized with the CanExecute code. I have no idea how to debug this. Any thought would be helpful!?!

  • windows phone deserialization json

    - by user2042227
    I have a weird issue. so I am making a few calls in my app to a webservice, which replies with data. However I am using a token based login system, so the first time the user enters the app I get a token from the webservice to login for that specific user and that token returns only that users details. The problem I am having is when the user changes I need to make the calls again, to get the new user's details, but using visual studio's breakpoint debugging, it shows the new user's token making the call however the problem is when the json is getting deserialized, it is as if it still reads the old data and deserializes that, when I exit my app with the new user it works fine, so its as if it is reading cached values, but I have no idea how to clear it? I am sure the new calls are being made and the problem lies with the deserializing, but I have tried clearing the values before deserializing them again, however nothing works. am I missing something with the json deserializer, how van I clear its cached values? here I make the call and set it not to cache so it makes a new call everytime: client.Headers[HttpRequestHeader.CacheControl] = "no-cache"; var token_details = await client.DownloadStringTaskAsync(uri); and here I deserialize the result, it is at this section the old data gets shown, so the raw json being shown inside "token_details" is correct, only once I deserialize the token_details, it shows the wrong data. deserialized = JsonConvert.DeserializeObject(token_details); and the class I am deserializing into is a simple class nothing special happening here, I have even tried making the constructor so that it clears the values each time it gets called. public class test { public string status { get; set; } public string name{ get; set; } public string birthday{ get; set; } public string errorDes{ get; set; } public test() { status = ""; name= ""; birthday= ""; errorDes= ""; } } uri's before making the calls: {https://whatever.co.za/token/?code=BEBCg==&id=WP7&junk=121edcd5-ad4d-4185-bef0-22a4d27f2d0c} - old call "UBCg==" - old reply {https://whatever.co.za/token/?code=ABCg==&id=WP7&junk=56cc2285-a5b8-401e-be21-fec8259de6dd} - new call "UBCg==" - new response which is the same response as old call as you can see i did attach a new GUID everytime i make the call, but then the new uri is read before making the downloadstringtaskasync method call, but it returns with the old data

  • Working through exercises in "Cocoa Programming for Mac OS X" - I'm stumped

    - by Zigrivers
    I've been working through the exercises in a book recommended here on stackoverflow, however I've run into a problem and after three days of banging my head on the wall, I think I need some help. I'm working through the "Speakline" exercise where we add a TableView to the interface and the table will display the "voices" that you can choose for the text to speech aspect of the program. I am having two problems that I can't seem to get to the bottom of: I get the following error: * Illegal NSTableView data source (). Must implement numberOfRowsInTableView: and tableView:objectValueForTableColumn:row: The tableView that is supposed to display the voices comes up blank I have a feeling that both of these problems are related. I'm including my interface code here: #import <Cocoa/Cocoa.h> @interface AppController : NSObject <NSSpeechSynthesizerDelegate, NSTableViewDelegate> { IBOutlet NSTextField *textField; NSSpeechSynthesizer *speechSynth; IBOutlet NSButton *stopButton; IBOutlet NSButton *startButton; IBOutlet NSTableView *tableView; NSArray *voiceList; } - (IBAction)sayIt:(id)sender; - (IBAction)stopIt:(id)sender; @end And my implementation code here: #import "AppController.h" @implementation AppController - (id)init { [super init]; //Log to help me understand what is happening NSLog(@"init"); speechSynth = [[NSSpeechSynthesizer alloc] initWithVoice:nil]; [speechSynth setDelegate:self]; voiceList = [[NSSpeechSynthesizer availableVoices] retain]; return self; } - (IBAction)sayIt:(id)sender { NSString *string = [[textField stringValue] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; //Is the string zero-length? if([string length] == 0) { NSLog(@"String from %@ is a string with a length of %d.", textField, [string length]); [speechSynth startSpeakingString:@"Please enter a phrase first."]; } [speechSynth startSpeakingString:string]; NSLog(@"Started to say: %@", string); [stopButton setEnabled:YES]; [startButton setEnabled:NO]; } - (IBAction)stopIt:(id)sender { NSLog(@"Stopping..."); [speechSynth stopSpeaking]; } - (void) speechSynthesizer:(NSSpeechSynthesizer *)sender didFinishSpeaking:(BOOL)complete { NSLog(@"Complete = %d", complete); [stopButton setEnabled:NO]; [startButton setEnabled:YES]; } - (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView { return [voiceList count]; } - (id)tableView: (NSTableView *)tv objecValueForTableColumn: (NSTableColumn *)tableColumn row:(NSInteger)row { NSString *v = [voiceList objectAtIndex:row]; NSLog(@"v = %@",v); NSDictionary *dict = [NSSpeechSynthesizer attributesForVoice:v]; return [dict objectForKey:NSVoiceName]; } /* - (BOOL)respondsToSelector:(SEL)aSelector { NSString *methodName = NSStringFromSelector(aSelector); NSLog(@"respondsToSelector: %@", methodName); return [super respondsToSelector:aSelector]; } */ @end Hopefully, you guys can see something obvious that I've missed. Thank you!

  • Writing a Virtual Printer in .NET

    I'm looking to create a virtual printer that passes data to my .NET application. I want to then create an installer that installs both the printer and the .NET application. It would we really nice to be able to write it all in C#, but I have a feeling that this will require a printer driver to be written is unmanaged code. Does anyone know of a fairly clean tutorial or example of how to do this?

  • Rails. Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?

  • pure as3 benefits to compiling with flex4 instead of flex3?

    - by jedierikb
    If I have a pure as3 project that I have been compiling with flex3 from mxmlc, is there any reason to switch to using the mxmlc with flex4? I can use all of the flash 10 language features like Vector, 3D, etc., so that is not a reason to switch (or is there something I can't do?). But maybe there is a performance boost? Or is the exact same compiling tool and the flex code base is the only difference?
