Or is there any other way to avoid that message box because each time the page loads i have to give yes and then proceed. By default i've to give yes is there any way to handle that using javascript.
help me out please...

Hi Chaps,

I have some Javascript code, that sucessfully exports Project data from an HTML table to an Excel SpreadSheet:
Code:

function ExportToExcel() {		
			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="Project Details";
			
			// Store the sheet header names in an array
			var rows = tbldisplay.getElementsByTagName("tr");
			var columns = tbldisplay.getElementsByTagName("th");
			var data = tbldisplay.getElementsByTagName("td");
			
			//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;
					d = d + 1;
				}
			}
			
			//autofit the columns
			XlSheet.columns.autofit;
			
			// Make visible:
			xlApp.visible = true;
			xlApp.DisplayAlerts = true;
			CollectGarbage();
			//xlApp.Quit();
}

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?

Hi,

Is there any way to use the activeX to execute a local aplication with parameters...

Example:
PHP Code:
<script>
var ws = new ActiveXObject("WScript.Shell");
ws.Exec("c:\\windows\\notepad.exe");
</script> 

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!

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)

Hi All,

Need some urgent.

We are having a javascript which is throwing the foll error

"Object doesn't support this property or method".

The javascript function being called is using a Scanner API. So this is using some ActiveX.


Below is the code for javascript

<script language="javascript">

// Initialize scanning
function OnLoad()
{
try
{
Scanner.OpenScanner();
// Scanner.ScanPriority = 0; // Set scanner to Foreground Read mode before enable scanning
// Scanner.EnableScanning(1);
document.forms["mobileform"]["rm07m-bwartwe[1]"].value = "101";
}
catch (e)
{
alert(e.message);
}
}

// Clean up
function OnUnload()
{
Scanner.CloseScanner();
// Calling Dispose is necessary for Pocket IE because of a Microsoft issue related to releasing object.
if (navigator.appName == "Microsoft Pocket Internet Explorer")
Scanner.Dispose();
}

// Scan through soft trigger
function Scan()
{
try
{
Scanner.SetSoftTrigger(1);
}
catch (e)
{
alert(e.message);
}
}

//User-defined function to format error codes.
//VBScript has a Hex() function but JScript does not.
function hex(nmb)
{
if (nmb > 0)
return nmb.toString(16);
else
return (nmb + 0x100000000).toString(16);
}

</script>

There is a object tag in html

<object id="Scanner"></object>

The javascript functions are called from body tag.

Can someone please provide some help.

Thanks,
Nikhil

Hi Chaps,

I have a Javascript ActiveX function that exports the contents of an HTML table into MS Excel. The script works fine, however, some of the dates have changed from dd/mm/yyyy to mm/dd/yyyy. I do not know why this is happening, especially as it's only to a few.
Here is the code:
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 = tblreport_work.getElementsByTagName("tr");
			var columns = tblreport_work.getElementsByTagName("th");
			var data = tblreport_work.getElementsByTagName("td");
			
  			// Set Excel Column Headers and formatting from array
			for(i=0;i<columns.length;i++){
				XlSheet.cells(1).value= "Projects - Open";
	   			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("B1:F1000").HorizontalAlignment = -4108;
				XlSheet.Range("H1:H1000").HorizontalAlignment = -4108;
				XlSheet.Range("J1:J1000").HorizontalAlignment = -4108;
			}
			
			//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;
					d = d + 1;
				}
			}
			
			//autofit the columns
			XlSheet.columns.autofit;
			
			// Make visible:
			xlApp.visible = true;
			xlApp.DisplayAlerts = true;
			CollectGarbage();
			//xlApp.Quit();
		}
}
</script>

Date Columns: F,G,I

If anyone has some ideas on how to correct this, I'd be most grateful!

hi, my problem is that .disabled only work in Firefox.
How do i make it work in other browses?
Below is the code i attached

        document.register.submitBtn.disabled=false;
    else
        document.register.submitBtn.disabled=true;

Hello,

I'd like to use the following code on my website:

<script type="text/javascript">
if(screen.width==1024)
{
document.write("<link rel='stylesheet' type='text/css' href='style1024.css' />");
}
else
{
document.write("<link rel='stylesheet' type='text/css' href='style.css' />");
}
</script>

This inserts a different css file when the screen width is 1024, as you can see,

BUT

the problem is, that this way if someone has js disabled, he sees the page with no css, which would be very bad.

So my question would be:

Is there a way to set that my website checks if javascript is enabled or not and if not, it sets the normal css somehow?

Thanks for your help.

I've used js only for simple form validations thus far. I've been working on a coldfusion/ajax dynamic select list for a few days and just about have it functioning the way I want it.

My question is this. Whats the best way, if any, to handle users who turn js off. What I mean is, I have so far three separate queries for my three select lists, and are populated with ajax calls. Is there a way to get the same functionality with standard queries and page refreshes in case a visitor does have js disabled?

Thanks for any tips and advice.

A general question really, but does anyone have a good technique or source for creating disabled versions of tool bar buttons?

Many thanks for any assistance,

S

Hi
I need to change the font color of the disabled textboxes of our application. These disabled textboxes exist at thousands of places both at pageload or disabled conditionally clientside.
I am aware that in IE8 there is no other way to change the fontcolor except use readonly. So i thought that maybe if I changed the .disabled property to something like -
Code:

Object.disabled {
    function set() {
        this.readOnly = value;
     }

    function get() {
         return this.readOnly;
     }
}

then it would make my task much easier. I searched and found out that Object.defineProperty ,may do the trick. However i am getting the mull reference error. Is there any other way?

Hi!

Code:

<script type="text/javascript">
                                            window.onload = function(){
                                       var check = document.getElementById('check1');
                                       var file = document.getElementById('file');
                                       var text = document.getElementById('text');
                                       check . onchange = function(){
                                          if( check.checked ){
                                              text.setAttribute('disabled', 'disabled');
                                              file.removeAttribute('disabled');
                                          }
                                          else{
                                              text.removeAttribute('disabled');
                                              file.setAttribute('disabled', 'disabled');
                                          }

                                       };
                                    };
                                    
                                        </script>
                                    <input id="check1" type="checkbox" name="check" /> From link!!!<br/>
                                    Poster:<input  id="file" type="file" name="poster"  />
                                    
                                    Poster from link:<input  id="text" type="text" name="postlink" /><br/>

I know it's expected behavior for disabled form elements not to post, because they cannot be successful. Fine. But even after I set disabled to false through a javascript function, the form elements will not get posted. Why is that?

Does anyone know a workaround?

Pseudo code he
Code:

<input type=text name=blah disabled=disabled />

function blah {
 all_blah = document.getElementsByName("blah");
 for (i=0; i<all_blah.length; i++)
 all_blah[i].disabled = false;
}

The intended form elements change their looks in browser, meaning they're enabled, I got javascript to acknowlegde they're enabled, but they still won't post.


Thanks for any insights.
