I use asp.net and this code for open local file with IE:
<script type="text/javascript" language="javascript">
function RunFile() {
WshShell = new ActiveXObject("WScript.Shell");
WshShell.Run("d:/11.doc", 1, false);
}
</script>
<input type="button" value="Run File" onclick="RunFile();"/>
result is ok :-)
but I want send address local file to script then run this file:
example:
<script type="text/javascript" language="javascript">
function RunFile() {
WshShell = new ActiveXObject("WScript.Shell");
WshShell.Run(**AddressFile**, 1, false);
}
</script>
protected void Page_Load(object sender, EventArgs e)
{
**AddressFile** = "d:/11.doc";
}
If you want to call the javascript function dynamically from server-side, simply add a parameter to the JS function to take the file name as so:
<script type="text/javascript" language="javascript">
function RunFile(fileName) {
WshShell = new ActiveXObject("WScript.Shell");
WshShell.Run(fileName, 1, false);
}
</script>
And then on server-side call the javascript function as so:
this.ClientScript.RegisterStartupScript(this.GetType()
,"somekey"
,"RunFile('"+file_parameter_on_server_side+"')",true)";
More details and full example here.

So when using signalR. I followed this example and got it working on a test web form, where in I open 2 tabs of the same page and tested it out:
SignalR Tutorial
Now I tried to modify it a little bit and tried to have 1 page as a sender and another as a receiver,
Page with Button to send message:
<script type="text/javascript">
$(function () {
// Declare a proxy to reference the hub.
var msg = $.connection.myHub1; //change MyHub1.cs should be in camel myHub
// Create a function that the hub can call to broadcast messages.
msg.client.broadcastMessage = function (name, message) {
// $("[id*=btnRefresh]").click();
};
// Start the connection.
$.connection.hub.start().done(function () {
function RefreshData() {
// Call the Send method on the hub.
msg.server.send('admin', 'Refresh Grid');
};
});
});
</script>
protected void btnSendMsg_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(GetType(), "SigalRFunction", "RefreshData()", true);
}
Page with gridview:
<asp:Button runat="server" ID="btnRefresh" OnClick="btnRefresh_Click" Style="display: none" />
<script type="text/javascript">
$(function () {
// Declare a proxy to reference the hub.
var msg = $.connection.myHub1; //change MyHub1.cs should be in camel myHub
// Create a function that the hub can call to broadcast messages.
msg.client.broadcastMessage = function (name, message) {
$("[id=btnRefresh]").click();
};
// Start the connection.
$.connection.hub.start().done(function () {
function RefreshData() {
// Call the Send method on the hub.
//msg.server.send('admin', 'Refresh Grid');
};
});
});
</script>
protected void btnRefresh_Click(object sender, EventArgs e)
{
grdview.DataSource = grdviewData();
grdview.DataBind();
}
My idea was every time a message is received, the grid view/page should should automatically refresh. The grdviewDatasource and Databind works i.e placed it in pageload.Sadly nothing happens.

Let me start by saying that you can invoke the hub's method either from client-side or code-behind code. Since it is not clear which way you want I'll cover both.
Your hub, MyHub1 should define the Send method, which you are going to invoke when the button is clicked:
MyHub1.cs
public class MyHub1 : Hub
{
public void Send(string name, string message)
{
var hubContext = GlobalHost.ConnectionManager.GetHubContext<MyHub1>();
hubContext.Clients.All.broadcastMessage(name, message);
}
}
Note that the Send method calls the broadcastMessage javascript function (to notify clients), which you should define in the Receiver. You should add any code necessary to refresh your grid inside that function.
Receiver.aspx
<script type="text/javascript">
$(function () {
var msg = $.connection.myHub1;
// Create a function that the hub can call to broadcast messages.
msg.client.broadcastMessage = function (name, message) {
console.log(name + ", " + message);
// do whatever you have to do to refresh the grid
};
// Start the connection.
$.connection.hub.start().done(function () {
});
});
</script>
The Sender contains the two buttons: btnSendMsg will invoke the hub's Send method from code-behind; btnSendMsg2 will perform the same invocation from javascript. You can pick either depending on your needs.
Sender.aspx
<form id="form1" runat="server">
<div>
<asp:Button ID="btnSendMsg" runat="server" Text="Server-Side" OnClick="btnSendMsg_Click" />
<input type="button" id="btnSendMsg2" value="Client-Side" />
</div>
</form>
<script type="text/javascript">
$(function () {
// Declare a proxy to reference the hub.
var msg = $.connection.myHub1;
// Start the connection.
$.connection.hub.start().done(function () {
$('#btnSendMsg2').click(function () {
// Call the Send method on the hub.
msg.server.send('admin', 'Refresh Grid');
});
});
});
</script>
Sender.aspx.cs
protected void btnSendMsg_Click(object sender, EventArgs e)
{
var myHub1 = new MyHub1();
myHub1.Send("admin", "Refresh Grid");
}
Last but not least, make sure both the sender and the receiver pages reference the necessary jQuery and SignalR scripts and the autogenerated SignalR hub script.
I've been searching for a longtime, How can I call my public void search() inside my javascript keypress. Newb in asp.net Thanks!

My client puts our below JS code in his website in the <head> and is complaining our tags are not firing. Below is the sample code from client:
<html>
<head>
<script type="text/javascript">
function create() {
try {
var baseURL = "https://serv2ssl.vizury.com/analyze/analyze.php?account_id=VIZVRM1125";
var analyze = document.createElement("iframe");
analyze.src = baseURL;
var node = document.getElementsByTagName("script")[0];
node.parentNode.insertBefore(analyze, node);
} catch (i) {
}
}
var existing = window.onload;
window.onload = function() {
if (existing) {
existing();
}
create();
}
</script>
</head>
<body onload="javascript:clientfunction();">
<script type="text/javascript">
function clientfunction()
{
//client code is replcad here
document.write("Hello testing");
}
</script>
</body>
</html>
On page Load clientfunction() is calling, our create() function is not firing.
Please can anybody help me why our tags are not firing and what is the alternative solution for this issue?
copy paste and check running following
<html>
<head>
<script type="text/javascript">
function create() {
alert("Gdfg");
try {
var baseURL = "https://serv2ssl.vizury.com/analyze/analyze.php?account_id=VIZVRM1125";
var analyze = document.createElement("iframe");
analyze.src = baseURL;
var node = document.getElementsByTagName("script")[0];
node.parentNode.insertBefore(analyze, node);
} catch (i) {
}
}
window.onload=create;
window.onload=clientfunction;
</script>

I'm a new programmer that learn javascript, Im new in js actually.
I have a task that require a web page able to read file in client directory. I've got some js code :
<html>
<script type="text/javascript">
function ReadWeight() {
var filePath = "file:///D:/Text.txt";
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET",filePath,false);
xmlhttp.send(null);
var fileContent = xmlhttp.responseText;
alert(fileContent);
}
ReadWeight();
</script>
<body>
</body>
</html>
When I save this code in my directory and access it by this link, It works well.
file:///D:/test.html
But when I put it in my localhost and I access it, the JS doesn't works.
Does my code incorrect when in web server?
Please help me out.
Might I suggest using an error console to display the error so people know how to help you? =] And paste it in your query
Download something like firebug and see if a request is being made (for FireFox)
It looks like you would rather want to access the file via the http:// protocol, instead of file://
As far as I know you can only read client files using an <input type="file"> element. Once you get the file you can read it multiple times:
HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>File Refresh</title>
<script src="filerefresh.js"></script>
</head>
<body>
<input id="fileInput" type="file">
<pre id="fileDisplay"></pre>
</body>
</html>
JavaScript:
(function() {
var sleepInterval = 1000; // 1 second
var fileInput;
var fileDisplay;
var reader;
var id = undefined;
function initialize() {
fileInput = document.getElementById("fileInput");
fileDisplay = document.getElementById("fileDisplay");
reader = new FileReader();
reader.onloadend = function() {
fileDisplay.innerHTML = reader.result;
reschedule();
};
fileInput.addEventListener("change", readFile);
}
function reschedule() {
if (id !== undefined) {
clearTimeout(id);
}
id = setTimeout(readFile, sleepInterval);
}
function readFile() {
reader.readAsText(fileInput.files[0]);
}
window.onload = initialize;
})();
I've been trying to run the code if any of the conditions get true. Its a dialog box which popups after postback created on Jquery Impromptu. I've tried to run the same code on a different project and its working fine however It doesn't show anything the condition met true
