VB.Net, Read a MultiLine textbox line by line?

Read a MultiLine textbox line by line?

Author	Message
Bigtog #1 / 5	Read a MultiLine textbox line by line? I am trying to figure out a way to read a textbox.Text line by line. I want to process each line just as though this line was a line in a text file or a single row of data. I want to be able to search inside each line and, based on the results of that search for specific keywords/etc, I want to process that line. I have searched and searched and cannot find anything that gives an example or shows me how to do it... Anyone have any ideas?

Steven Bras [M #2 / 5	Read a MultiLine textbox line by line? Because the text in the box does not necessarily have line-break characters (ie, carriage return/linefeed combinations) at the end of each line, you won't be able to determine where each line ends. The problem would probably be eliminated if you used a listbox instead; then you can grab each list item and parse it. Alternatively, if you can force users to hit ctrl-enter to end a line, you can determine where the line breaks by looking for ascii 13, (chr(13)), which is the carriage return. Hope this helps.

Michael Harri #4 / 5	Read a MultiLine textbox line by line? Why wouldn't the Lines property of a TextBox be applicable here, assuming we _aren't_ talking about a TextBox with WordWrap on??? -- Michael Harris Microsoft.MVP.Scripting -- Quote: > Because the text in the box does not necessarily have line-break characters > (ie, carriage return/linefeed combinations) at the end of each line, you > won't be able to determine where each line ends. > The problem would probably be eliminated if you used a listbox instead; > then you can grab each list item and parse it. > Alternatively, if you can force users to hit ctrl-enter to end a line, you > can determine where the line breaks by looking for ascii 13, (chr(13)), > which is the carriage return. > Hope this helps. > Steven Bras, MCSD > Microsoft Developer Support/Visual Basic WebData > This posting is provided "AS IS" with no warranties, and confers no rights. > Are you secure?

Steven Bras [M #5 / 5	Read a MultiLine textbox line by line? That's a good point; however, the Lines property only returns individual lines if they are delimited with a carriage return. Thus the user will still have to use the ctrl-enter combination to delineate the input.
