I have an application that generates large number of printed pages (in the neighborhood of 20,000). Occasionally one of them appears as blank when it should contain an output. Is there a way to detect a blank page during the print page event?

My boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc... How to understand other person or team's website or web application that was written in asp or asp.net and vb or vb.net?

This combo box is databound to a SQL backend, so when it is filled it has a blank at the top of the list. I am assuming this is added because of the NULL at the bottom of the SQL table. Is there a way to remove this entry?
I have tried the following:
.items.remove("") ' does not work, i added this after the population command
.items.removeAt(0) ' This gave me an exception stating that it could not be used because the datasource was used This is the code i use to fill the combobox on form load:
With ManufacturerComboBox
.DisplayMember = "Manufacturer"
.ValueMember = "ManufacturerID"

I'm implementing a feature which reads comma separated txt file from server(one line at a time). Format of file is fixed, There are 3 columns on each row. After reading the row from file I insert it in a database table. But first value of each row aoutomatically appends two blank spaces, even if there are no blank spaces at the begining of each row. I tried to use "TRIM/LTRIM/Replace" to remove blank spece from the first value of each row, but didn't succeed.

To reduce the size of some images I have, I'd like to remove the white padding that some have. The idea would be that if one has large white areas on the borders, then those can be cropped to save some space.

I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.

So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer
Pages = New Integer() {1, 3}
PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.

The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:
