# Save generated output to folder instead of displaying in browser

Hi Experts

My code below takes the current html of a page and creates a PDF. I am struggling to find a way to save the PDF into a folder instead of showing it in the browser

Dim htmlToPdf = New HtmlToPdfConverter()
Dim pdfData = htmlToPdf.GeneratePdf(html)
Response.ContentType = "application/pdf"
Response.OutputStream.Write(pdfData, 0, pdfData.Length)
Response.[End]()

Replace lines 3 - 5 with:

System.IO.File.WriteAllBytes("path\to\folder", pdfData)  ' First parameter may need to change
'  to Server.MapPath("path\to\folder")
'  depending on which folder you are
'  referencing

Thank you it tries to do it then says

 System.Web.HttpException: A page can have only one server-side Form tag.


I tried it with

 Public Overrides Sub VerifyRenderingInServerForm(control As Control)
End Sub


and without but get the same error

I have placed the line as follows

System.IO.File.WriteAllBytes(Server.MapPath("~\PDF\test.pdf"), pdfData)

That sounds like an issue in your markup file, not your code-behind file. Do you have two <form> tags in your HTML somewhere?

I have also noticed that if I remove the only form tag and place the code in the form load, everything works fine however this renders the form useless as none of the controls work without the form tag.

This is how I am generating the html

  'Generate from current page
Dim renderedOutput As StringBuilder
Dim strWriter As StringWriter
Dim tWriter As HtmlTextWriter
Dim html As String

'create a HtmlTextWriter to use for rendering the page
renderedOutput = New StringBuilder
strWriter = New StringWriter(renderedOutput)
tWriter = New HtmlTextWriter(strWriter)
'render the page output
Page.RenderControl(tWriter)
html = renderedOutput.ToString


Maybe if I change that it'll work? Is there any other way to get the HTML of the current page?
