We recently moved our application from .Net 4.0 to .Net 4.5. After that, our few component which were based on ActiveX component stopped working IE.
After a lot research , we found a solution. As with launch of .Net, Hosting managed controls inside IE is no longer supported out of the box.
Further Details : http://msdn.microsoft.com/en-us/library/hh367887.aspx
Here is one way that you can use if you want to load ActiveX Control in IE 10.
Solution:
There is registry key called as "EnableIEHosting". This key needs to be added at two location:
- HKLM\SOFTWARE\MICROSOFT\.NETFramework
- HKLM\SOFTWARE\Wow6432Node\Microsoft\.NETFramework
Please create key of type "dword" and set its value to 1 e.g.
"EnableIEHosting"=dword:00000001
Thats it! You ActiveX controls are all set to load in IE 10 on any Windows operating system with .NET 4.5
You can create these entries either using code or simple run a batch file.
Create Batch File :
REGEDIT4
; @ECHO OFF
; CLS
; REGEDIT.EXE /S "%~f0"
; EXIT
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework]
"EnableIEHosting"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework]
"EnableIEHosting"=dword:00000001
Pause
Copy this content and save it in file ".bat" extension. No code needed :)
Hope it helps!
Recently, we were working on requirement where we need a search result like "facebook friend search" which returns in following format:
To get it working, we used jQuery's Autocomplete feature. Three steps to implement same.
1. A Text box.
2. You need data to display. If you are searching using a service, you can call using Ajax that returns a set of results and bind it.
3. Display in following a way is tricky :) i'll explain in detail as given below.
Lets start :
Step 1. Create a Text-box as follows:
<body>
<input id="friends" />
</body>
Step 2. Call service using Ajax and prepare data-set to bind.
$("#friends").autocomplete({
source: function (request, response) {
$.ajax({
url: '<Service Url>',
type: "GET",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.Data, function (item) {
return {
Name: item.Name,
ImageUrl: item.ImageUrl
}
}));
}
});
},
minLength: 2,
select: function (event, ui) {
log(ui.item ?
"Selected: " + ui.item.label :
"Nothing selected, input was " + this.value);
},
open: function () {
$(this).removeClass("ui-corner-all").addClass("ui-corner-top");
},
close: function () {
$(this).removeClass("ui-corner-top").addClass("ui-corner-all");
}
});
Note: source method is populated with results returned by service call. We have name and image url there. It creates a a list of data as needed.
We can also assign some static data if needed like:
$(function() {
var availableTags = [
"x",
"y",
"y",
"z"
];
$( "#friends" ).autocomplete({
source: availableTags
});
Step 3: Create result like Facebook i.e. Image with text.
jQuery's data attribute and renderItem function finish that job for us.it can be used to create custom html in response flowing out as a result. We can apply required CSS as needed.
$("#friends").autocomplete({
source: function (request, response) {
$.ajax({
url: '<Service Url>',
type: "GET",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.Data, function (item) {
return {
Name: item.Name,
ImageUrl: item.ImageUrl
}
}));
}
});
},
minLength: 2,
select: function (event, ui) {
log(ui.item ?
"Selected: " + ui.item.label :
"Nothing selected, input was " + this.value);
},
open: function () {
$(this).removeClass("ui-corner-all").addClass("ui-corner-top");
},
close: function () {
$(this).removeClass("ui-corner-top").addClass("ui-corner-all");
}
}).data( "autocomplete" )._renderItem = function( ul, item ) {
var inner_html = '<a><div class="list_item_container"><div class="image"><img src="' + item.ImageUrl + '"></div><div class="label">' + item.Name + '</div></div></a>';
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append(inner_html)
.appendTo( ul );
};
});
Thats it! Task done.. Thanks to jQuery and its power.. simply awesome.
