I am using Xam.Plugin.HtmlLabel for showing data on my project. It is working fine on android and windows. But nothing is showing in ios devices.
My code:
<htmllabel:HtmlLabel
x:Name="message_label"
VerticalOptions="Start"
VerticalTextAlignment="Center"
TextColor="Black">
<htmllabel:HtmlLabel.FontSize>
<OnIdiom x:TypeArguments="x:Double">
<OnIdiom.Phone>20</OnIdiom.Phone>
<OnIdiom.Tablet>30</OnIdiom.Tablet>
<OnIdiom.Desktop>20</OnIdiom.Desktop>
</OnIdiom>
</htmllabel:HtmlLabel.FontSize>
</htmllabel:HtmlLabel>
message_label.Text = "htmldata";
I have uploaded a sample here for the reference.
In your case , you seems forget to init the renderer in specific platforms .
in iOS
using LabelHtml.Forms.Plugin.iOS;
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
HtmlLabelRenderer.Initialize();
global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
return base.FinishedLaunching(app, options);
}
I used the tag <u> to add under line of the label .
You could check the demo from https://github.com/luczha/HtmlLabel_demo .

On page load i have a controller that calls a service and then binds the returned data to some $scope.objects:
app.controller("MainController", function($scope, $http, serviceGetData) {
serviceGetData.getData(function(data) {
$scope.LoginCount = data.LoginCount;
$scope.ProductInfo = data.ProductInfo;
$scope.ProfileInfo = data.ProfileInfo;
// Delayed binding
$scope.OrderHistory = { History: [] };
}
$scope.populateModel = function(model, values) {
var isArray = $.isArray(values);
$.each(values, function(key, value) {
if (isArray) {
key = this.key;
value = this.value;
}
if (model[key] !== value) {
model[key] = value;
}
});
};
}
And in my HTML, i try to bind $scope.OrderHistory by:
<h1><a href="#" ng-click="populateModel(OrderHistory , { History: OrderEntries })" >View order details</a></h1>
This is fine when viewing on laptops/desktops, but not working in tablet and mobile devices e.g. iphone/ipad
Try to add the ngTouch. From documentation:
A more powerful replacement for the default ngClick designed to be used on touchscreen devices. Most mobile browsers wait about 300ms after a tap-and-release before sending the click event. This version handles them immediately, and then prevents the following click event from propagating.
Requires the ngTouch module to be installed.
I had the same problem.
I tried adding the ngTouch library and dependency, but was still having a problem.
My static <div> elements which contained an ng-click worked fine, but the div's which were created dynamically (in an ng-repeat on the same webpage) which contained an ng-click didn't work. Tapping on them just didn't do anything.
This happened on my iPhone 6, my iPad and in Google Chrome when I asked to view my webpage on any of the device types. When I viewed the same webpage in IE or regular Chrome, all of the ng-clicks worked fine.
The solution was to use the ngMobileClick directive described here and changing my ng-click's to ng-mobile-click.
After doing that, my dynamically created click events did get triggered normally when I tapped on them on a device.
Very odd.
Had a similar issue where the ng-click inside of a ng-repeat would not trigger.
I fixed this by adding $event.stopPropagation()
Ex:
<li ng-repeat="option in $scope.options">
<span><a ng-click="trigger(); $event.stopPropagation()"></a></span>
</li>
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#
Can I make link into setting in phone from my application? For example like a link to other page (NavigateTo)?
I would like to make buttun, witch navigate you to mobile setting....
thanks for the answer.
Check this link. You can do that by invoking LaunchUriAsync method passing one of available settings Uri as parameter :
public async void OpenSettings(string settingsName)
{
var op = await Windows.System.Launcher.LaunchUriAsync(new Uri(settingsName));
}
Available Uri :
1. ms-settings-airplanemode: .
2. ms-settings-bluetooth:
3. ms-settings-cellular:
4. ms-settings-emailandaccounts:
5. ms-settings-location:
6. ms-settings-power:
7. ms-settings-screenrotation:
8. ms-settings-wifi:
I've started using LibTiff.NET for writing tiff IPTC tags lately and discovered strange behavior on some files that i have here. I'm using sample code that ships with LibTiff.NET binaries, and it works fine with most of the images, but some files are having image data corruption after these lines:
class Program
{
private const TiffTag TIFFTAG_GDAL_METADATA = (TiffTag)42112;
private static Tiff.TiffExtendProc m_parentExtender;
public static void TagExtender(Tiff tif)
{
TiffFieldInfo[] tiffFieldInfo =
{
new TiffFieldInfo(TIFFTAG_GDAL_METADATA, -1, -1, TiffType.ASCII,
FieldBit.Custom, true, false, "GDALMetadata"),
};
tif.MergeFieldInfo(tiffFieldInfo, tiffFieldInfo.Length);
if (m_parentExtender != null)
m_parentExtender(tif);
}
public static void Main(string[] args)
{
// Register the extender callback
// It's a good idea to keep track of the previous tag extender (if any) so that we can call it
// from our extender allowing a chain of customizations to take effect.
m_parentExtender = Tiff.SetTagExtender(TagExtender);
string destFile = #"d:\00000641(tiffed).tif";
File.Copy(#"d:\00000641.tif", destFile);
//Console.WriteLine("Hello World!");
// TODO: Implement Functionality Here
using (Tiff image = Tiff.Open(destFile, "a"))
{
// we should rewind to first directory (first image) because of append mode
image.SetDirectory(0);
// set the custom tag
string value = "<GDALMetadata>\n<Item name=\"IMG_GUID\">" +
"817C0168-0688-45CD-B799-CF8C4DE9AB2B</Item>\n<Item" +
" name=\"LAYER_TYPE\" sample=\"0\">athematic</Item>\n</GDALMetadata>";
image.SetField(TIFFTAG_GDAL_METADATA, value);
// rewrites directory saving new tag
image.CheckpointDirectory();
}
// restore previous tag extender
Tiff.SetTagExtender(m_parentExtender);
Console.Write("Press any key to continue . . . ");
Console.ReadKey(true);
}
}
After opening i see mostly blank white image or multiple black and white lines instead of text that have been written there (i don't need to read\write tags to produce this behavior). I noticed this happens when image already has a custom tag (console window alerts about it) or one of tags have got 'bad value' (console window in this case says 'vsetfield:%pathToTiffFile%: bad value 0 for "%TagName%" tag').
Original image: http://dl.dropbox.com/u/1476402/00000641.tif
Image after LibTiff.NET: http://dl.dropbox.com/u/1476402/00000641%28tiffed%29.tif
I would be grateful for any help provided.
You probably should not use CheckpointDirectory method for files opened in append mode. Try using RewriteDirectory method instead.
It will rewrite the directory, but instead of place it at it's old
location (as WriteDirectory() would) it will place them at the end of
the file, correcting the pointer from the preceeding directory or file
header to point to it's new location. This is particularly important
in cases where the size of the directory and pointed to data has
grown, so it won’t fit in the space available at the old location.
Note that this will result in the loss of the previously used
directory space.
I wanted to save the google map into an image from a webpage.
while i was searching for that i got this program.
http://www.codres.de/downloads/gms.exe[^]
besides other alternatives like print screen i wanted to use a program or map api which can save a specified dimension of google map instead of the screen.
i have used browser component in c# for http access and for displaying certain webpages.
I want to know whether there are options to capture the browser screen to image using any c# functionality or even the browser component would have given such options. just a guess.
i would like to have answers, suggestions on how to capture the map with custom dimension and zoom size to an image.
I used this to get captcha Image from the current page, so you can use similar code just amend the imageID to point to the google map image and use this solution for zooming.
public string newsavefunction(WebBrowser webBrowser1)
{
IHTMLDocument2 doc = (IHTMLDocument2)webBrowser1.Document.DomDocument;
IHTMLControlRange imgRange = (IHTMLControlRange)((HTMLBody)doc.body).createControlRange();
string imagename = string.Empty;
try
{
foreach (IHTMLImgElement img in doc.images)
{
imgRange.add((IHTMLControlElement)img);
imgRange.execCommand("Copy", false, null);
using (Bitmap bmp = (Bitmap)Clipboard.GetDataObject().GetData(DataFormats.Bitmap))
{
bmp.Save(#"F:\captchaimages\captchapic.jpg");
}
imagename = img.nameProp;
break;
}
}
catch (System.Exception exp)
{ }
return imagename;
}
