View 14 RepliesI am trying to append a new line to a text file. Sometimes it posts to a new line (like I want it to) and sometimes it appends to the current line, consequently screwing up my read. I even put VbNewLine in the code.
Here is the snippet:
Dim outputline2 As String
outputline2 = equip & "," & value
Dim myfile2 = File.AppendText("equiped.txt")
myfile2.WriteLine(outputline2, vbNewLine)

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky.

I use a text file to store the settings from my program.Now when i save the settings the text file gets created and everything works correctly. I can load the settings without any error.Now when i quit my program and star it up again clicking the load button will clear out any data in my text file. So the file still exist but it empty.It happens when my program runs this line of code.
Dim o_read As system.IO.streamReader = system.IO.File.OpenText("C: est.txt")
That just tells o_read that it is a stream reader and which file to read.How does my file get cleared out by that?

View 2 RepliesI am attempting to append information to a textbox in VB. My app allows the user to choose a variety of options and displays all the information in a single, read-only text box.
I would like to set it up so every time an event triggers something to be written in the text box, it gets appended instead of overwriting the text currently in the box.
The only constraint is that text should be appended as a new line, not directly after the last sentence.

Say I've got a variable that contains multiple words, each one separated by a newline. What I'm trying to do is add specific text to the end of each line in that variable.
For example, say the variable contains...
alpha
bravo
charlie
etc
etc.
And say the text I want to append is "newtext"
So then I'd like the output to look like...
alpha newtext
bravo newtext
charlie newtext
etc
etc
What I tried to do is to split that variable into an array (separated by newline), and then use a For Each to append the newtext to each line in the array. But it's obvious I haven't messed around with VB in a long time, as something is wrong with my logic. Here's what I've got...
Dim Text_Array() As String
Dim OriginalText As String
Dim OutputText As String
