| Post subject: | VB 2010 Form to PDF |
In my application I create an Invoice is a VB form and print it as a screen snapshot using BitBlt. I need to provide email functionality and I think creating s PDF using PDFSharp and emailing that pdf file would be the best option. Is it possible to input the BitBlt screen snapshot to PDFSharp? Thank you in anticipation. Brad |

Why don't you e-mail the screen shot as a GIF or PNG file? A screen shot in a PDF file will still be a screen shot - and when people zoom in or print it it will look like a screen shot. You might use MigraDoc to re-create the invoice. Fonts will then be smooth even when zoomed at the highest level and it can look like an invoice, not like a screen shot. Yep, it's extra work - but it might be worth it. |

Hello Thomas, Thank you for your response, I have decided to use PDFSharp's Drawstring capability to create the invoice rather than use VB forms and grab that portion of the screen. By using Drawstring I have more control, however I can't find how to create multiple pages. I won't always know how many pages I will print some invoices are one page some may be 5 or ten pages. I can add a new page using document.addpage() but when I try to use drawstring I overwrite the first page - still referring to the first page. Do you have a sample of creating a multiple page document? Thanks again for an excellent product. Brad |

If you create a new page, also create a graphics object to draw on the new page. Or better use MigraDoc when you need automatic page breaks. There even is a MigraDoc Invoice sample ... |

Thomas, The PDFSharp is working well and creating multiple pages. I am having another concern with the document.save, at times its almost immediate and others it can take up to 20-25 seconds to save the file. Is there anything I can do to speed this up?? Thanks again Brad |

So maybe this problem is not with PDFsharp (a hard disk that has to speed up, a network connection causing delay, DDLs being loaded for the first time, or something completely different). |

Thanks Thomas, I'll look elsewhere for the cause. Its very erratic some times the save is immediate other times its up to 28 seconds. Very confusing. Brad |
