View 4 Replieswhat is the height of a regular PDF page in pixels?
i heard it was something like this:
Dim pgSize As New iTextSharp.text.Rectangle(595, 792)
but i am adding an image that takes up maybe half the height, and even though pgSize looks like a full page and the image takes up only half of it, i am getting a height of like 619 for the image? i do not know if it is in the same units?

View 4 RepliesI need to read PDF Page size of an existing PDF. I have both itextsharp and acrobat used in my project. This is what I've tried.
Dim pagesize As Rectangle
Dim reader As PdfReader = New PdfReader(formfile)
pagesize = reader.GetPageSize(1)
If pagesize.Width = "396" Then
Testing = "Y"
Else
Testing = "N"
End If
I get page size as = {Rectangle: 396x309.6 (rot: 0 degrees)}
And Testing comes out = Y
This seemed great at first, until I found that I get those exact same values regardless of how big the pdf is...so now i'm back to square one not knowing where to turn. Interesting thing to note though When I hover my mouse over reader.GetPageSize(1), nothing shows up while debugging, but pagesize does get the value stated above.
Like the title says i'd like to read an existing pdf page size with VB.Net. I've been working with Itext.Sharp, and the Acrobat.dll.

View 4 RepliesI am adding watermark text to PDFs in a class library I have created. The code I posted below works fine, however the watermark is sometimes difficult to read because it overlays with content on the PDF. How would I go about adding a white background color around the watermark text? I basically would like the watermark text to be surrounded inside a white rectangle the size of the text.

how can I insert text into an existing string? I am trying to interpret a solution in an earlier post "How do I insert test into a textbox in the middl of existing text"
solution given was int insertionlocation = 4;string newText = "text to insert";if (textBox1.Text.Length < insertionlocation) textBox1.Text = textBox1.Text.Substring(0, insertionlocation) + newText + textBox1.Text.Substring(insertionlocation); else textBox1.Text = textBox1.Text + newText;
I must determine both how and where I need to implement this solution.What follows is my work in progress. Keep in mind things are added and deleted as I work with it saving a user entry to a file

What is the simplest way to check for an existing file. Every method shown to me in my text and the information gained from the Visual Studio help doesn't seem to work. Each one of them tells me the syntax is wrong. I just want a simple way to check for an existing text file that is in the defualt file location.MSDN told me to use FileSystem.FileExists(file) - VS would not take this and...My text Tony Gaddis (VB 2008) shows:
If File.Exists(FileName) Then

Not sure what I am doing wrong here but I have 2 buttons and a rich text box. The issue is when I click the second button to add text to the rich text box and it over writes the current text that is already in the rich text box.
