CommandManager not found Windows Phone - windows-phone-8

I'm doing a Windows Phone app and I'm trying to add en event to CommandManager.RequerySuggest. But it does not compile telling me that CommandManager does not exist. I have put the reference System.Windows.Input.
Thanks for the help.
Ps:I may I created a Silverlight app, I dont remember lol and I am on vs2013.
Edit: Part of the code:
public event EventHandler CanExecuteChanged
{
add
{
if (this.canExecute != null)
CommandManager.RequerySuggested += value;
}
remove
{
if (this.canExecute != null)
CommandManager.RequerySuggested -= value;
}
}
In my references, I just have Windows Phone and .Net for Windows Phone

If you're sure that you've already added the using System.Windows.Input , then try adding PresentationCore within your References.

Is there a way to have a bookmark be created upon clicking a button/link?

I'm trying to figure out if it's possible to make it so that if you click a link or button, a bookmark will be created. Anything that comes up on Google has to do with ebooks, and I can't seem to find anything. If anyone has the answer, it would be a huge help!
function addFavorites(a) {
pageTitle = document.title;
pageURL = document.location;
try {
// Internet Explorer solution
eval("window.external.AddFa-vorite(pageURL, pageTitle)".replace(/-/g, ''));
} catch (e) {
try {
// Mozilla Firefox solution
window.sidebar.addPanel(pageTitle, pageURL, "");
} catch (e) {
// Opera solution
if (typeof(opera) == "object") {
a.rel = "sidebar";
a.title = pageTitle;
a.url = pageURL;
return true;
} else {
// The rest browsers (i.e Chrome, Safari)
alert('Press ' + (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ? 'Cmd' : 'Ctrl') + '+D to bookmark this page.');
}
}
}
return false;
}
Add to Favorites

Be aware of eval()
eval() may be a dangerous function under certain circumstances, which executes the code it's passed with the privileges of the caller.
Get advised by Mozilla.org and use with caution
No, there's no stright forward way for that.
Opera, Google Chrome and Safari do not provide a way to add new elements to the Favorites (Bookmarks) from JavaScript.
There was an API for that however, which is the Window.external API, and I believe it used to work as window.external.AddFavorite() in Internet Explorer, and window.sidebar.addPanel() in Firefox (obsolete, deprecated, i.e. dead, see for the API).
Not sure this info would help, but you might have to create a browser extension for that, then connect your button with your extension, this way you can ensure its stability.
My suggestion is to simply ask the users to bookmark the webpage they're in if that would help to solve the problem you're trying to solve (not sure what you're trying to create).

Move Window in mfc c++ without titlebar?

I am using this code to move the window. But this code does not work well. When I click anywhere on windows from it will move but i just want to move windows form. When i click on specific think. For example picture. I am using MFC C++ HtmlDialog. Anyone know how to do that?
DHTML_EVENT_ONCLICK(_T("image"), PreTranslateMessage)
BOOL CHtmlDlgTestDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_MOUSEMOVE && (pMsg->wParam & MK_LBUTTON))
{
CPoint p;
GetCursorPos(&p);
CRect r;
GetWindowRect(&r);
if (r.PtInRect(p))
{
ReleaseCapture();
SendMessage(WM_NCLBUTTONDOWN, HTCAPTION, 0);
SendMessage(WM_NCLBUTTONUP, HTCAPTION, 0);
return 1;
}
}
return CDialog::PreTranslateMessage(pMsg);
}
WM_NCLBUTTONDOWN is a notification message, Windows sends this message and the program responds to it. The program should not send this message to Windows. In this case it works but it's not recommended.
I don't know how this code works: DHTML_EVENT_ONCLICK(_T("image"), PreTranslateMessage) it probably gets ignored and you can remove it. PreTranslateMessage is still called. You can restrict it to any rectangle within the Window, for example CRect(50,50,200,200):
BOOL CHtmlDlgTestDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_MOUSEMOVE && (pMsg->wParam & MK_LBUTTON))
{
CPoint p = pMsg->pt;
ScreenToClient(&p);
CRect r(50,50,200,200);
if (r.PtInRect(p))
{
ReleaseCapture();
SendMessage(WM_NCLBUTTONDOWN, HTCAPTION, 0);
SendMessage(WM_NCLBUTTONUP, HTCAPTION, 0);
return 1;
}
}
return CDialog::PreTranslateMessage(pMsg);
}
If you want to move an element within the window you can use javascript:
Moveable/draggable <div>
Ps, normally you should use WM_NCHITTEST as explained earlier. This case is very unusual because it's HTML dialog. You should reconsider putting a normal title bar which users understand, or you could put html control within a dialog, then you can control the rest of the dialog with standard WinApi.

Input Validation for PhoneTextBox in windows phone app 8

i'm developing a windows phone application.in my application i want to make input validation for textbox.i'm using windows phone toolkit :PhoneTextBox
need to alert a Message when user fail to fill the textbox after click the submit button.is there any way to do that?
thanks!
In your Button_click event, add a condition,
if (!String.IsNullOrEmpty(PhoneTextBox.Text))
{
//your action here
}
In your Button's event handler make sure you have:
your eventhandler(){
if(string.IsNullOrWhiteSpace(this.textBox1.Text)) //here "tb" is the textbox name, in case of that give your textbox's name.
{
MessageBox.Show("TextBox is empty");
}
}
Or else try using String.IsNullOrWhiteSpace in order to check whether the string is empty.
if (String.IsNullOrWhiteSpace(Name)) //give the name of your textbox.Text
{
//Handled
}
Reference: String.IsNullOrWhiteSpace Method
On Button_click you have to check. Try following code.
if (!String.IsNullOrEmpty(YourTextBox.Text)) // it check it text box is null or empty
{
//your action here
}

hash key "#" stripped from ussd code in "tel:" links on html pages

Good day all.
I have a simple link on a webpage, in where the user can call an USSD number:
*CLICK HERE AND CALL *111*2#
this is pretty straight forward; now, if I test it on desktop browser, it popups an alert asking me if I want to call (with skype) the number *111*2#, and thats ok.
with my Android phone (S Note 3), when testing this page, the phone (or something) stripped out the last "#" (only the last) from the link, resulting in a call to *111*2.
does anyone has experienced this? or knows how to prevent this?
Use URL encoding for special character in a URL. For example # equals %23
This worked for me:
<a ng-href="tel:%23 224">#224</a>
As you can see:
You need to use Uri.encode("#")
For example String number = "tel:*111*2" + Uri.encode("#");
Try this way,hope this will help you to solve your problem.
webview = (WebView) findViewById(R.id.webview);
webview.loadData("*CLICK HERE AND CALL *111*2#","text/html", "utf-16");
webview.setWebViewClient(new CustomWebViewClient());
private class CustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView wv, String url) {
if(url.startsWith("tel:")) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse(url.replace("#","%23")));
startActivity(intent);
return true;
}
return false;
}
}
You can use below way to display the USSD in dialer
*CLICK HERE AND CALL *111*2#

With a browser, how do I know which decimal separator does the operating system use?

I'm developing a web application.
I need to display some decimal data correctly so that it can be copied and pasted into a certain GUI application that is not under my control.
The GUI application is locale sensitive and it accepts only the correct decimal separator which is set in the system.
I can guess the decimal separator from Accept-Language and the guess will be correct in 95% cases, but sometimes it fails.
Is there any way to do it on server side (preferably, so that I can collect statistics), or on client side?
Update:
The whole point of the task is doing it automatically.
In fact, this webapp is a kind of online interface to a legacy GUI which helps to fill the forms correctly.
The kind of users that use it mostly have no idea on what a decimal separator is.
The Accept-Language solution is implemented and works, but I'd like to improve it.
Update2:
I need to retrive a very specific setting: decimal separator set in Control Panel / Regional and Language Options / Regional Options / Customize.
I deal with four kinds of operating systems:
Russian Windows with a comma as a DS (80%).
English Windows with a period as a DS (15%).
Russian Windows with a period as a DS to make poorly written English applications work (4%).
English Windows with a comma as a DS to make poorly written Russian applications work (1%).
All 100% of clients are in Russia and the legacy application deals with Russian goverment-issued forms, so asking for a country will yield 100% of Russian Federation, and GeoIP will yield 80% of Russian Federation and 20% of other (incorrect) answers.
Here is a simple JavaScript function that will return this information. Tested in Firefox, IE6, and IE7. I had to close and restart my browser in between every change to the setting under Control Panel / Regional and Language Options / Regional Options / Customize. However, it picked up not only the comma and period, but also oddball custom things, like the letter "a".
function whatDecimalSeparator() {
var n = 1.1;
n = n.toLocaleString().substring(1, 2);
return n;
}
function whatDecimalSeparator() {
var n = 1.1;
n = n.toLocaleString().substring(1, 2);
return n;
}
console.log('You use "' + whatDecimalSeparator() + '" as Decimal seprator');
Does this help?
Retrieving separators for the current or a given locale is possible using Intl.NumberFormat#formatToParts.
function getDecimalSeparator(locale) {
const numberWithDecimalSeparator = 1.1;
return Intl.NumberFormat(locale)
.formatToParts(numberWithDecimalSeparator)
.find(part => part.type === 'decimal')
.value;
}
It only works for browsers supporting the Intl API. Otherwise it requires an Intl polyfill
Examples:
> getDecimalSeparator()
"."
> getDecimalSeparator('fr-FR')
","
Bonus:
We could extend it to retrieve either the decimal or group separator of a given locale:
function getSeparator(locale, separatorType) {
const numberWithGroupAndDecimalSeparator = 1000.1;
return Intl.NumberFormat(locale)
.formatToParts(numberWithGroupAndDecimalSeparator)
.find(part => part.type === separatorType)
.value;
}
Examples:
> getSeparator('en-US', 'decimal')
"."
> getSeparator('en-US', 'group')
","
> getSeparator('fr-FR', 'decimal')
","
> getSeparator('fr-FR', 'group')
" "
Ask the user, do not guess. Have a setting for it in your web application.
Edited to add:
I think it is ok to guess the default setting that works ok, say, 95% of the time. What I meant was that the user should still be able to override whatever guesses the software made. I've been frustrated too many times already when a software tries to be too smart and does not allow to be corrected.
Why not
console.log(0.1.toLocaleString().replace(/\d/g, ''));
function getDecimalSeparator() {
//fallback
var decSep = ".";
try {
// this works in FF, Chrome, IE, Safari and Opera
var sep = parseFloat(3/2).toLocaleString().substring(1,2);
if (sep === '.' || sep === ',') {
decSep = sep;
}
} catch(e){}
return decSep;
}
I can guess the decimal separator from
Accept-Language and the guess will be
correct in 95% cases, but sometimes it
fails.
This is IMO the best course of action. In order to handle the failures, add a link to set it manually next to the display area.
Using other people answers I compiled the following decimal and thousand separators utility functions:
var decimalSeparator = function() {
return (1.1).toLocaleString().substring(1, 2);
};
var thousandSeparator = function() {
return (1000).toLocaleString().substring(1, 2);
};
Enjoy!
Similar to other answers, but compressed as a constant:
const decimal=.1.toLocaleString().substr(1,1); //returns "." in Canada
Also, to get the thousands separator:
const thousands=1234..toLocaleString().substr(1,1); //returns "," in Canada
Just place the code at the top of your JS and then call as required to return the symbol.
For example (where I live), to remove commas from "1,234,567":
console.log( "1,234,567".replaceAll(thousands,"") ); //prints "1234567" to console.
I think you have to rely on JavaScript to give you the locale settings.
But apparently JS doesn't have direct access to this information.
I see Dojo Toolkit relies on an external database to find the locale information, although it might not take in account setting changes, for example.
Another workaround I see is to have a small silent Java applet that query this information from the system, and JavaScript to get it out of Java.
I can give more information if you don't know how to do it (if you want to go this convoluted route, of course).
[EDIT]
So I updated my knowledge of localization support in Java...
Unlike what I thought originally, you won't have directly the decimal separator or thousand separator characters directly, like you would do with line separator or path separator: instead Java offers APIs to format the numbers or dates you provide.
Somehow, it makes sense: in Europe you often put the currency symbol after the number, some countries (India?) have a more complex rule to separate digits, etc.
Another thing: Java correctly finds the current locale from the system, but doesn't take information from there (perhaps for above reasons). Instead it uses its own set of rules. So if you have a Spanish locale where you replaced decimal separator with an exclamation sign, Java won't use it (but perhaps neither your application, anyway...).
So I am writing an applet exposing a service (functions) to JavaScript, allowing to format numbers to the current locale. You can use it as such, using JavaScript to format numbers on the browser. Or you can just feed it with some sample number and extract the symbols from there, using them locally or feeding them back to the server.
I finish and test my applet and post it there soon.
OK, I have something to show, more a proof of concept than a finished product, but because of lack of precise specifications, I leave it this way (or I will over-engineer it). I post in a separate message because it will be a bit long.
I took the opportunity to try a bit more jQuery...
The Java code:
GetLocaleInfo.java
import java.applet.*;
import java.util.Locale;
import java.text.*;
public class GetLocaleInfo extends Applet
{
Locale loc;
NumberFormat nf;
NumberFormat cnf;
NumberFormat pnf;
// For running as plain application
public static void main(String args[])
{
final Applet applet = new GetLocaleInfo();
applet.init();
applet.start();
}
public void init() // Applet is loaded
{
// Use current locale
loc = Locale.getDefault();
nf = NumberFormat.getInstance();
cnf = NumberFormat.getCurrencyInstance();
pnf = NumberFormat.getPercentInstance();
}
public void start() // Applet should start
{
// Following output goes to Java console
System.out.println(GetLocaleInformation());
System.out.println(nf.format(0.1));
System.out.println(cnf.format(1.0));
System.out.println(pnf.format(0.01));
}
public String GetLocaleInformation()
{
return String.format("Locale for %s: country=%s (%s / %s), lang=%s (%s / %s), variant=%s (%s)",
loc.getDisplayName(),
loc.getDisplayCountry(),
loc.getCountry(),
loc.getISO3Country(),
loc.getDisplayLanguage(),
loc.getLanguage(),
loc.getISO3Language(),
loc.getDisplayVariant(),
loc.getVariant()
);
}
public String FormatNumber(String number)
{
double value = 0;
try
{
value = Double.parseDouble(number);
}
catch (NumberFormatException nfe)
{
return "!";
}
return nf.format(value);
}
public String FormatCurrency(String number)
{
double value = 0;
try
{
value = Double.parseDouble(number);
}
catch (NumberFormatException nfe)
{
return "!";
}
return cnf.format(value);
}
public String FormatPercent(String number)
{
double value = 0;
try
{
value = Double.parseDouble(number);
}
catch (NumberFormatException nfe)
{
return "!";
}
return pnf.format(value);
}
}

Tested on Firefox 3.0, IE 6, Safari 3.1 and Opera 9.50, on Windows XP Pro SP3.
It works without problem with the first two, on Safari I have a strange error after init() call:
java.net.MalformedURLException: no protocol:
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at sun.plugin.liveconnect.SecureInvocation.checkLiveConnectCaller(Unknown Source)

at sun.plugin.liveconnect.SecureInvocation$2.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at sun.plugin.liveconnect.SecureInvocation.CallMethod(Unknown Source)
but it still works.
I can't get it work with Opera: the applet loads correctly, as I can see the trace of init() call in the Java console, I have no errors when JavaScript calls the Java functions (except if I add and call a method getting a JSObject parameter, curiously), but the Java functions are not called (I added trace of the calls).
I believe Liveconnect works in Opera, but I don't see yet how. I will research a bit more.
[Update] I removed references to non-existing jar file (which doesn't stop other browsers) and I got a trace of the calls, but it doesn't update the page.
Mmm, if I do alert(applet.GetLocaleInformation()); I got the information, so it might be a jQuery issue.
Even if you knew what locale this "GUI Application" is running under, you still have to figure out how it is getting the current locale, and how it is determining the decimal separator.
i don't know how it is done on a Mac, but on Windows applications are supposed to interrogte the user's preferences set via the Control Panel. It's quite possible this mystery applicaiton is ignoring those settings, and using their own internal setup instead.
Or perhaps they're taking the current locale, and inferring the rest, rather than being told.
Even then, in english, numbers are given in groups of 3 digits, with a comma separating the groups. i.e.:
5,197,359,078
Unless the number was an integer that contains a phone number:
519-735-9078
Unless of course the number was an integer that contains an account number:
5197359078
In which case, you're back to hard-coded overridden logic.
Edit: Removed currency example, since currency has its own formatting rules.
"Is there any way to do it on server
side (preferably, so that I can
collect statistics), or on client
side?"
No you can't. That GUI is looking at some user or machine specific settings.
First, you probably do not know at what settings this UI is looking.
Second, with a webapplication you will probably not be able to check these settings (clientside --> Javacsript).
Is there any way to do it on server side (preferably, so that I can collect statistics), or on client side?
from Server side. That could get decimal separator from system by (.NET)
string x = CultureInfo.CurrentCulture.NumberFormat.NumberDsecimalSeparator;
The rest of work is check delimiter for exporting which is different from x
comma (",") or semicolon (";") in case csv export
Another possible solution: You could use something like GeoIP (example in PHP) to determine the user's location and decide based on these information.
