Trim Images Crop To Remove All Blank Areas?
Aug 21, 2010
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 has multiple blank lines and Im trying to return all the lines between two of them specifically
so if I have a file that looks like this:
[Code].....
I would like to grab lines 8-13. Unfortunately, it might not always be 8-13 as it could be 9-20 or 7-8, but it will however always be between the 2nd and 3rd line break.
I know how to trim characters and pull out singular lines, but I have no idea how to trim entire sections.

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.

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.
'Read Multiline File
Dim FILE_NAME As String = "C: empliz-etsy.txt"

If System.IO.File.Exists(FILE_NAME) = True Then
