Did you consider using ITextSharp.. It creates PDF's on the fly.

Hi Abhishek,
Thanks for you comments, Yes pdf creation on the fly it's no problem in ITextSharp  .
But problem with Office related file conversion.

Yes. I was also stuck with this point. You need conversion of PDF not to create on the fly !!!

Hi,
We are planning to crawl/spider few property websites using .NET technology. Here we need to crawl the search page and all its results pages.
Would you please let me know all the names spaces and concepts which we need to go through to do this job?
Kindly also refer if you find any good doc/url references.
Many thanks.
Regards,
Reshma.

There are different option that you can use to do it. You can use HTTPWebReqest and HTTPWebResponse for that. Now how to do it, for that you need to explore google. If stuck during implementation ask over here.

Hi,
Have you tried a upload action in a test page?? If not, you can have a try.
I don't think any script tag will be added to your site with upload action, but if your pc got virus...anything will happen.

hello,
I have a gridview in a webpage where i use a datatable to populate the gridview,but only if the website is built and rebuilt the webpage works properly without exceptions,as the datatable does not retain any data that has been asign to it on the button click.
Following is the code,
static DataTable dtvalues = new DataTable();
public static IICDServices icdObj;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
}
}
private void Createdatatable()
{
dtvalues.Columns.Add("DL_No");
dtvalues.Columns.Add("F_Name");
dtvalues.Columns.Add("M_Name");
dtvalues.Columns.Add("L_Name");
dtvalues.Columns.Add("Unit");
dtvalues.Columns.Add("Birth_Date");
dtvalues.Columns.Add("Mobile_No");
}
for which i have written the following code
{
DataRow drvalues = dtvalues.NewRow();
drvalues["DL_No"] = TxtDLNO.Text.ToUpper();
drvalues["F_Name"] = txtFname.Text;
drvalues["M_Name"] = txtMName.Text;
drvalues["L_Name"] = txtLName.Text;
drvalues["Unit"] = ddlUnit.SelectedItem.Text;
drvalues["Birth_Date"] = Gmdatepicker3.Date;
drvalues["Mobile_No"] = TxtMobileNo.Text;
dtvalues.Rows.Add(drvalues);
GridView1.DataSource = dtvalues;
GridView1.DataBind();
TxtDLNO.Text = "";
txtFname.Text = "";
txtMName.Text = "";
txtLName.Text = "";
TxtMobileNo.Text = "";
}
on the submit button click i want to redirect this page back to itself but it throws an exception as the page has npt been rebuilt.
please help me out with this.
thanks.

Why you are not adding <b> </b> tag with the text for first three item of the list.

I can not do that because I don't know exactly text for the first three items of the list until my web application runs.
Text is added to my listbox by the following way:
foreach (DataRow row in dt.Rows)
{
string Msg = string.Format("{0} : {1}", row["Id"], row["Name_"]);
lstHisttory.Items.Add(Msg);
}

Hi All,
I want to ask what is the best way to have the link to a file expire after a set time, so that the user gets sent a download link via email which they only have access to for say 24 hours.
Thanks
|

Yes... Do the logic in the database.
Say you want the user to download a file. Place a log in the server of the file and use GUID for its identification.
When you create the email pass the Guid as query string.Thus if your download is
http://www.yourserver.com/filedown.dat?tid=xxxx-xxx-xxx
Thus the tid will represent the actual Guid link. Now create an http handler for .dat extension(or whatever you like). Now when user navigates to the site, check if the GUID is valid and also validate the time between the link sent and the actual request time. Based on that you might show appropriate message.
Note: This is a logic which I thought might be a solution.There are lots of others too, and you can choose any of them which suits you. Tell me if you have already thought any.

Hi Abhishek,
Thank you for your reply.
I had thought to use a GUID and store the time, but hadn't thought to use a http handler. I'll look into that. I'm new to Asp.net and wanted to check the GUID / database was the right way to go as I had an idea it was, but I just wasn't sure.
All the best

|

Yes... Go on to create a handler. Yes.. GUID will point to a time for the current user. As I stated, GUID will represents the entire record on the download.
If you dont want to httphandler, you might also go on creating a page. So that the navurl looks like
http://yourserver.com/download.aspx?id=xxx-xxx-xxx
This is the same thing. You might use either way. Infact page is also a IHttpHandler.
Cheers.

Well we can stick a timestamp in the url and retrieve it and cross check against the current time. saving dataspace and processing time on server.
also if one wants could salt the time stamp and decrypt. I am in the process to implement it. Let me now
