View 4 RepliesI don't know if this forum is the appropriate place for the question, but here it goes.I need a hand of someone who knows "iTextSharp" - it was created mainly to build PDFs, but I am using "PdfReader" function to retrieve all the plain text out of existing PDF files, in my VB.net project.

Using C# program I am reading CSV File with value like (Name, Salary, Age) (A, $1,200, 27) (B, 2300, 27)In the header row there are three columns. I want to validate that the number of columns in data rows is also three. (C, 28) should be an invalid file.
View 3 Repliesi have a webrowser and i need to find about 10 links all begining with [URL], from the html code of that site. The websites in the code wont be clickable, they are usually listed on a forum. The end of the link above can be diferent, so im not sure how you could find the end point. No assumptions can be made as to the code that will be after the link, as every website is different. The link then needs to listed in a listbox for further processing.
View 6 RepliesI already know the basic procedure of how to read specific cells of an .xls file using VB.NET but I can't figure out how to automatically get all the data from such a file.Basically, I'm obtaining the data like this:
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
xlApp = New Excel.Application
[code]....
In this case, I know that there will be content in the first 10 rows of the columns A, B and C but what would I have to do if I had a huge document whose size and content might even change from time to time? I know that there is also an attribute ws.rows.count but this always returns a big value like 60000 even if only a few rows are occupied.So basically, I'm looking for a simple way to loop through all the used rows of an Excel file with the possibility of accessing each cell in that row.

My app currently sends GET httpwberequests and parses the content after reading the response stream for each request and the repeats this process over and over. I need to implement a continuous http stream which uses the same GET request but the connection stays open, from what I understand. how would I change my existing code to do this?

I'm trying to read the content of a field in a mysql database. I found this code below that does it but you must select the position of the field (column 0, 1, 2 etc) myData.GetString(1) instead of the name of the field. In the php code above it is "title". I'm looking for a command like myData.GetString("title")

I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

View 2 RepliesI have a bunch of PDFs that I'm just trying to open, resize the page, and then save. I'm also hoping that the file sizes will shrink significantly doing so.

View 2 RepliesI have an instance where I have a logo image as part of some artwork..If a user uploads a new logo I have a form field which is larger than the default logo.I then use that form field to position the new image.
The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo..
what I have done is:foreach (var imageField in imageReplacements)
{
fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null);
fields.RegenerateField(imageField.Key);
PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber);
float[] logoArea = fields.GetFieldPositions(imageField.Key);
[Code]...
The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.is there a way to set a stacking order on layers?
why my tables are lapping over each other?
Dim datatable As PdfPTable = New PdfPTable(4)

even though im decrementing last_pos by the height of the previous table, they still lap over in a weird way like this:
for this line: c.WidthPercentage = 100F
i am getting this error:Error 1'WidthPercentage' is not a member of 'iTextSharp.text.Table'.
here's the entire code. it's taken directly from the tutorial

I need to convert fdf files to pdf in asp.net using vb. I found some code that I'm trying to learn from. What I would like to do is upload the fdf file and then output a pdf to a directory and email it out. The fdf files are coming from a shared linux/php host (using the php fdf functions is all I can do here on this host) that are emailed to a central inbox. I'm going to pick up the files from the inbox and upload them to a win/asp.net box to convert to pdf.The code i found is below.
* Dim pdfFlat As New MemoryStream() * Dim pdfReader As New PdfReader(context.Request.MapPath(pdfFormFileName)) * Dim pdfStamper As New PdfStamper(pdfReader, pdfFlat) * ' bind fields from fdf... * Dim fdfReader As New FdfReader(context.Request.InputStream) * Dim pdfForm As AcroFields = pdfStamper.AcroFields *
