How to search PDFs

[victor64]

Hello,

I need help on how to search PDFs in a folder from text entered in a text box, list the PDF file names which contains the text in a list box and click on the filenames from the listbox to open the PDF. Can you please help me with the sample codes or links related to this topic.

Thanks in advance.

Sounds quite possible..

You need to find out how to list files in a given path, example:-

Dim TempFile As IO.FileInfo
Dim CurrentDirectory as string ="C:\myfolder"

Dim FileSearch As New System.IO.DirectoryInfo(CurrentDirectory)
FoundFiles = FileSearch.GetFiles("*.pdf")


'update the list box
ListBox1.Items.Clear()

For Each tempfile In FoundFiles

ListBox1.Items.Add(tempfile.ToString)

Next

That should stick any PDF files found in your listbox.



To launch the reader, you need to lookup how to launch programs from vb.net, hint.. "new process" and "StartInfo". Then lookup the acrobat reader parameters. Optionally you could use "shell".


Hope that helps.

The code above is not tested by the way but should work.

I need to search for a text enterted in the textbox, if found in the pdf, then I would like to add the filename in my listbox. Do you now the code that would allow me to do that?

Ah sorry I misundertood what you meant.. You actually want to search the contents of the PDF files and then return any files that contain the search string?

I found this on google, CodeProject: Converting PDF to Text in C#. Free source code and programming help, not sure if it has any clues though..
