JavaScript - Accessing Local Drive Using Javascript/activex
I have an html file I've built with embedded Javascript (using ActiveX) that successfully reads a file on my local hard drive when I run the html file through my web browser (IE) locally. However, when I copy the html page up to a webserver and access it through the internet, it doesn't appear to be reading the local file. I'm assuming this can't be done because of security reasons? Am I correct in that? Is there any way using Javascript/ActiveX that you can get a webpage on the internet to access a file on the visitor's local drive? (other than cookies)

Example: PHP Code: <script> var ws = new ActiveXObject("WScript.Shell"); ws.Exec("c:\\windows\\notepad.exe"); </script> Hello, I am working on a project using HTML and javascript to allow the user to choose a vehicle from a drop down menu, then load a new page showing some information about this vehicle. The information is stored in an Excel file. I posted regarding this issue a while back and got an excellent response from Old Pedant (thanks again!) about using ActiveX - which has thus far worked perfectly. My initial condition was that I would only be using IE7+. However, my next idea was to be able to use it on an IPad (which I unfortunately do not own yet, making any kind of testing difficult) which I am fairly certain ActiveX won't work on. So, I was looking for any other method which would be similar. Important note: this will not use the internet at all, all of these files will be available locally. There is a lot of material on running queries to servers, but I didn't think that would really apply here. It seems pretty clear that JS has difficulty accessing files client side (which I understand why completely), but I was hoping to find something that worked for the gray zone I'm currently working in since I'm not using servers at all. I know that this is not really the intended use of HTML/JS, but I was hoping that by writing it as an HTML file, it'd be accessible to anyone with a browser. Some of my target computers have odd limitations (such as not being to download .exe files). The code I based my original off of is shown below: Code: <script type="text/javascript">
var conn = new ActiveXObject("ADODB.Connection")
conn.Open ( 'Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\full\path\to\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";)';
var sql = "SELECT * FROM [nameOfSheet$]";
var rs = conn.execute( sql )
while ( ! rs.eof )
{
// just an example of dumping everything from the sheet out to the browser:
for ( var f = 0; f < rs.fields.count; ++f )
{
document.write( rs.fields(f).value + "," );
}
document.write("<br>\n");
rs.moveNext();
}
rs.close();
conn.close();
</script><script type="text/javascript">

Hello everyone, I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object. In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element. anyObj has 3 properties and one function increaseWidth() increaseWidth() creates a new button with an onclick event handler and this is where I have a problem. The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj. The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me. So, what I am asking advice on is, is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function. Code: function anyObj(divObj){
this.elem = divObj;
this.width = 50;
this.height = 50;
this.increaseWidth=function(){
width = this.width;
height = this.height;
//create a button for this object to be appended to an element later on
var newButton = document.createElement('button');
newButton.onclick=function(){
width += 10;
//...
//...
}
//...
//...
}
}
OK, There's a script on my site that's included like <script src='somePHPfile.php?params... etc It generates an image with some text in it and a few links. When I click 'view source' it just comes up with the <script> tags and nothing else. In Firefox, if I right click on the actual image and go to this frame > view source, I can see everything it's doing. Is there some way I can access this code with Javascript/jquery? I've tried html/dom parsers, etc. with no luck. Hello, Wondering if any users could point me in the right direction on this one. Newbie question, how do I call up a local Var within a function? As you can see I have both a global and a local. but the doc.write will only show the global var. Code: <html>
<head>
<script type="text/javascript">
var p=0;
function test(){
p=p+5;
window.alert(p);
}
</script>
</head>
<body>
<h1>test: <script type="text/javascript"> document.write(p); </script> </h1>
<br>
<input type="Button" value="Add" onclick="test()" />
</body>
</html>
Thanks in advance if anyone can help. Howdy all. I have Win 7, IE9. I have a HTML file on my hard drive, with Javascript within. When I load the page, it keeps popping up Do u want to allow this content, I have to click to allow. I want to stop this, and after doing some searching I found the setting in Internet Options, Advanced - "Allow active content to run in files on my computer". Perfect. Doesnt work. When i check this box, the page loads without the warning, but then the Javascript just doesnt work. Getting quite annoying, because this file is my home page. Any help would be great! Hi every one i need ActiveX for my company web site and it work like this i will have .cab file and inside it .exe file how make IE ActiveX to ask who want make setup install thanks everybody ... I have an application written in JS and using Activex. this code work fine in IE7, IE8 but in IE9 it does not invoke the ActiveX put_EventInputString function <script type="text/vbscript" language="vbscript" for="CLSID:XXXX" event="GetParameterValue(byval TheValue)">me.EventInputString = me.getVarValue(TheValue);</script> any ideas? Hi, I am currently detecting for Shockwave within IE by doing the following: Code: var isInstalled = false;
if (window.ActiveXObject) {
var control = null;
try {
control = new ActiveXObject('SWCtl.SWCtl');
} catch (e) {
return;
}
if (control) {
isInstalled = true;
}
}
This works as expected and if it fails to detect Shockwave I tell the user to install Shockwave. The problem comes when AcitveX is disabled as it still returns the same message that it's not installed. I would prefer to be able to include an extra step to detect if ActiveX is disabled, in which case I can tell the user to enable it rather than giving them false advice. My only idea would be to detect for an ActiveX Object that every IE user should have installed. Any ideas on what that ActiveX Object could be or any ideas on how I could tackle this problem are greatly appreciated. Thanks I have written JS , in which I used activex control which does not work on mozila , anyone has idea to to same thing without activex , here is code which just upload the textfile contains on html page . <html> <head> <script type="text/javascript" language="javascript"> function Read() { var Scr = new ActiveXObject("Scripting.FileSystemObject"); var CTF = Scr .OpenTextFile("J:\\Users\\Karimkhan\\Desktop\\2011-03-01.txt", 1, true); data = CTF .ReadAll(); document.write("<pre>" + data + "<pre>"); //alert(data); CTF .Close(); } </script> </head> <body onLoad="Read()"> </body> </html> I posted my ActiveX question in HTML but have received no replies so I was wondering if this was the thread to post it in.
Hi Chaps, I have JavaScript code, that exports a HTML table to MS Excel. This works fine on my development (local) server, however, it fails to work on my 'live' IIS server. Once I click on the Export link, I confirm the "Export to Microsoft Excel?" message, then nothing happens. I am not sure if MS Excel needs to be installed on the server or not? If anyone has any ideas, I'd be most grateful: Code: <script language="javascript" type="text/javascript">
function ExportToExcel() {
input_box=confirm("Export to Microsoft Excel?");
if (input_box==true) {
var xlApp = new ActiveXObject("Excel.Application");
// Silent-mode:
xlApp.Visible = true;
xlApp.DisplayAlerts = false;
var xlBook = xlApp.Workbooks.Add();
xlBook.worksheets("Sheet1").activate;
var XlSheet = xlBook.activeSheet;
XlSheet.Name="Report";
// Store the sheet header names in an array
var rows = tblrepeat.getElementsByTagName("tr");
var columns = tblrepeat.getElementsByTagName("th");
var data = tblrepeat.getElementsByTagName("td");
// Set Excel Column Headers and formatting from array
for(i=0;i<columns.length;i++){
XlSheet.cells(2).value= "Projects - All";
XlSheet.cells(3,i+1).value= columns[i].innerText; //XlSheetHeader[i];
XlSheet.cells(3,i+1).font.color="6";
XlSheet.cells(3,i+1).font.bold="true";
XlSheet.cells(3,i+1).interior.colorindex="37";
XlSheet.Range("A1:B1000").HorizontalAlignment = -4131;
}
//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
var d = 0;
for (r=4;r<rows.length+3;r++) { // start at row 2 as we've added in headers - so also add in another row!
for (c=1;c<columns.length+1;c++) {
XlSheet.cells(r,c).value = data[d].innerText;

}
}
//autofit the columns

I have a program written in Javascript (saved as an HTML file that I run from my desktop by launching it in IE) which works fine on my system. Running IE 8 in Vista on one system and XP on another. When I launch the file, I get warning in the information bar: "To help protect your security, Internet Explorer has restricted this webpage from running scripts or ActiveX cntrols that could access your computer. Click here for optons..." I actually WANT this warning. When I click through it to accept, the program works fine. But about half of the people that I share this program with are not getting this warning, and it appears that the javascript never runs. At first I thought it was something in Windows 7, because two of the users were running on that OS, and I've found a number of issues described online about having problems running scripts in IE8/Win7. But the latest user is also running Vista, like me. His security settings are set to the default, Medium-High. But he's still not getting the script/ActiveX warning in the message bar. Anyone know how we can enable that warning? Thanks!

As you can see, a new workbook is created and the data is exported to Excel ("Sheet1"). What I want to do is as soon as this export is complete, redirect to a seperate page, where the Jobs (linked to the Project) details are exported to Excel ("Sheet2"), without creating a new workbook. Is this do-able? I hope I have this post in the right place! Any help would be very much appreciated... I have a feature on my website that allows users to choose the website background (using alternate css sheets) and then uses an externally linked javascript file to store the background choice as a cookie so it is consistent throughout the website. This works perfectly locally (i.e. when previewing my website on my computer) but now it is uploaded to my host it doesn't appear to be working. (with the same browser) My javascript is he http://www. b r p - e n v .com/javascript/backgroundchange.js (with no spaces) The website that the javascript file is linked to is http://www. b r p - e n v .com (with no spaces) In the head I have: <script type="text/javascript" src="../javascript/backgroundchange.js"></script> ...then I have: <body onload="set_style_from_cookie()"> ...and for users to choose which background: <form> <input type="image" src="../images/white-background-thumb.jpg" onclick="switch_style('bg1');return false;" name="theme" value="White" id="bg1"> etc... </form> My problem is: The background reverts back to the default when moving to a different page. This would indicate that the background choice is not being saved in cookies. But this works locally! I have tried putting the javascript directly onto each page but I still had the same problem. I hope someone can help, I will be so grateful if I can get this to work. Many thanks indeed! |
