Error
'C:\Documents and Settings\........' is not a valid virtual path in ASP . NET
I give my Code below ...
code in button Click
---------------------------
String fileName = "";
String strText = "";
// create instance of the PDF manager
IPdfManager objPDF = new PdfManager();
// Create new document
IPdfDocument objDoc = objPDF.CreateDocument(Missing.Value);
// Add a page to document. Pages are intentionally small to demonstrate text spanning
IPdfPage objPage = objDoc.Pages.Add(300, 300, Missing.Value);
// use Arial font
IPdfFont objFont = objDoc.Fonts["Arial", Missing.Value];
fileName = Path.GetFullPath(fileUpload1.PostedFile.FileName);

IPdfParam objParam = objPDF.CreateParam("x=10; y=290; width=280; height=280; html=true");
while (strText.Length > 0)
{
// DrawText returns the number of characters that fit in the box allocated.
int nCharsPrinted = objPage.Canvas.DrawText(strText, objParam, objFont);
// HTML tag generated by DrawText to reflect current font state
String strHtmlTag = objPage.Canvas.HtmlTag;
// The entire string printed? Exit loop.
if (nCharsPrinted == strText.Length)
break;
// Otherwise print remaining text on next page
objPage = objPage.NextPage;
strText = strHtmlTag + strText.Substring(nCharsPrinted);
}

Says it all really. ASP.NET cannot access your C: drive. It can only access its own virtual directory.

Give permissions to IISWPG user group. Notice that it can cause security leak.

Hi,
In my application i require to create a folder by customername, when any new customer is added. But the folder should be created on the Server not on workstation.
if is use following code, where the folder will be created, C Drive of Local Machine or C drive of Web Server.
Dim diCust As DirectoryInfo = Directory.CreateDirectory("C:/TestCustomer")
I want to create on Server.

If your application is placed on web server and you are running from there then folder will be created there other than if you run your application from local machine then it will be created on local machine drive.
please don't forget to vote on the post that helped you.

thanks for your thought Imran.
As its web application, One will run the application through URL from local machine. There is no general point to use application from server.
So where the folder will be created ?
Does i require to map Server Path.
Thanks

In Asp.Net applications folders and files always created at server. If you know the path directly you can write it as c:\..... but if the path will be depended to the directory of application is running you should use Server.MapPath. Using Server mappath is good for any changes of application directory or web server.
EX
if application is running at c:\inetpub\wwwroot\exapplication
Server.MapPath() gives you the result c:\inetpub\wwwroot\exapplication
Server.MapPath("Example") gives you the result c:\inetpub\wwwroot\exapplication\Example

Thanks Tamer,
Now i am pretty much clear about it.
I hosted my application on IIS, tested using URL from different machine, it creates folder on server machine only.
Again thanks for your addition.

Don't capitalise your question. If you want people to answer it, make it clear and concise. Putting the letters in upper case will just deter people from reading and/or answering your question.

Hi,
I have a popup form where I have to return values selected in a listbox through javascript to the parent form.... the list box is an asp.net control so how do we go about reading its values through javascript and passing them to the parent ? 
Code, Code, Code, chill lol.
|

One way would be to use a hidden field, which get's posted back to the parent.
Set the value of the hidden field to whatever you want, maybe a comma delimited list of selections from the list box.
In aspx:
<asp:hiddenfield id="thehiddenfield" runat="server" />
<script type="text/javascript">
function setHiddenField(val)
{
var el = document.getElementById(_hiddenFieldId);
el.value = val;
}
</script>
Somewhere in your Page_Load handler:
Page.ClientScript.RegisterClientScriptBlock(typeof(theform), "hiddenvar", "var _hiddenFieldId='" & thehiddenfield.ClientID & "';", true);
Note: You could just use view page source to find out the id of the hidden input field to set, if you don't want to go through all the hoops, but if it's in a control or master page and get's moved, you'll have to update the id.
Now, when your page posts back, the hidden field will be set to whatever you set it to and you can access it in the code behind using something like:
string vals = thehiddenfield.Value.ToString();
Hope that makes sense, it's kind of convoluted (but then again, so is asp.net  ).

Hi, thanks for the reply ! It was really helpful. I have managed to implement the hidden field solution partially in a sense.
Actually I have the javascript on the insert page of the child window (popup) which sets the return value on the parent (I'm using only 1 value of a textbox atm)
Now I have to loop through the values of the asp.net control listbox but through javascript and then insert them on the parent page.
Like on the popup page,
the user selects multiple items thorugh a grid which gets added to a listbox and then on the insert button I have to return all the values added on the listbox to the parent page text box.
Any help in this regard is appreciated.
Thanks !
Code, Code, Code, chill lol.

Great, glad you got it sort of working
To get the selected values from your multi-select list box your can iterate through the options of the select element:
var lb = document.getElementById("yourlistbox");
var selections = "";
for (var i = 0; i < lb.options.length; i++)
if (lb.options[ i ].selected)
if (selections.length > 0)
selections += "|";
selections += lb.options[i].value;
This creates an pipe "|" delimited string of selected values. Not sure how you're going to pass them back to the parent, maybe in the url as a parameter:
self.opener.location = "parentpage.aspx?selections=" + escape(selections);
Then in your parent page you can look at Request["selections"] and parse them.
Hope that helps!

hooray ! thanks so much for the reply !
I managed to get your code working . Its returning the values as well but I'm having a problem in setting the values to the textbox on the parent page.I am trying to set it via window.opener method. But its always displaying the last value on the list box 
here is part of my code for reference.
for(var i=0;i <list.options.length;>{
alert(list.options[i].value);
window.opener.document.getElementById(Str3).value=list.options[i].value+";";
}
window.close();
Code, Code, Code, chill lol.

Try:
var val = "";
for(var i=0;i < list.options.length; i++) {
val += list.options[i].value+";";
}
window.opener.document.getElementById(Str3).value=val;
window.close();
