I have a string which contains many rows of data which has been converted from a datatable. The last row of my string has nothing within it, no spaces or anything. How can I get rid of this row? I have tried regex, but cant seem to get anything that does the job. I am writing in VB.[code]...
Basically I've got a list of items in a text file, but sometimes a blank line gets inadvertently put in there, and I need to be able to delete that line (or change that line to a set value, either is fine).
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.

I am creating an application which uses OleDb to connect to an Excel spreadsheet and read the data into DataTable. The problem that I am having is that some of the columns I am getting are coming up blank, I've managed to narrow down that this is because that the first few lines for that column are blank. As unfortunately this is valid in the context of the Excel spreadsheet as not all dates etc. are required to be filled in. I was wondering whether anyone knows of any way that I could go about ensuring that the columns are populated by the OleDbDataReader even if the first x number of rows have that column as blank.
