View 1 RepliesIs it possible to scan a text document to a computer and then programmatically search for text within that document? It doesn't seem likely since the scanned document would be an image but I'm hoping one of the gurus on here might have a solution.

I thought this would be a server thing but the server admin and the security guy both said they didn't know. We already have a firewall and antivirus software, I just want to know how things work with native ASP.Net controls and not a product to try.

Can not find the way to change the font size and color, when exported to a PDF file. I want to format the text...
Before converting a gridview to PDF I can modify the font size and color using:
gridview.HeaderRow.Style.Add("font-family","Arial, Helvetica, sans-serif;"); gridview.HeaderRow.Style.Add("font-size","7.20px"); gridview.HeaderRow.Style.Add("color","#284775");
gridview.Style.Add("font-family","Arial, Helvetica, sans-serif;");
gridview.Style.Add("font-size","6px");
The gridview has different column widths because of the information that is being displayed, those sizes are set .aspx file. But, the generated pdf file auto adjusts the width of each column to be the same size, therefore the information is shrinked and doesnt look good..
I tried the following:
gridview.Width =100;
or
gridview.Style.Add("width","100");
or
gridview.Columns[3].ItemStyle.Width =Unit.Pixel(10);
And many more but haven't been able to adjust the gridview to it's original columns width. How can I do that?
This is the code I use to generate the PDF file:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
