under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
To read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
I am wanting to extract data line by line into labels(each line of data to go into a new label)In the example (picture), only one label is showen.

I would like to print out my debug message with line number in VB.net application.I did like this,
Dim st As StackTrace
Dim sf As StackFramee
st = New StackTrace(New StackFrame(True))[code]........
I wanna put the snippet to a class, everytime I call logMsg method to log my message with line number in source code.But I found if I put the snippet above into a class, the line number was always same, that's the line which I new 'st'.The function is exact same with _LINE macro in C++.

I want to print receipts with long spool of custom made paper through Epson LX-300 dotmatrix printer without stop. The idea is that if I can print a line at a time, and then add a few blank lines to space it in between, that will be great. You know, send a line of a text at a time to a printer. But I do not know how to do it with VB2005. If I use Crystal Report, it will insist to print the whole page! While the length of the receipt is always different depending upon the numbers of things purchased.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
View 8 RepliesI have a text file (CSV) approx 100k lines (8Mb). I want to search the entire file for a particular string eg, "apple" and for all lines containing the string to be printed in a text box. have successfully done this using streamReader to parse the CSV and check each element against the search word eg. apple. This has proven to be very very slow and I have read that the "ReadAllLines" method is much faster.

can somone just post a code of
1. Writing the last line of .txt into textbox1
2. Adding line from textbox to .txt
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
