So far this forum has been awesome answering my questions in full. I am very new to Visual Basic but I enjoy learning about it greatly. My question now is I now need to get all of my answers lined up neatly in the listbox using "zoning." Now I have know clue how to start this. Basically I need to make this..
Sum: 5 = 2 + 3
Difference: -1 = 2 - 3
Product: 6 = 2 * 3
[code].....
First off the listbox needs to show the equations for the number entered between 0 and 12 example:
1+1=2
1+2=3
1+3=4
[Code]....
I have a "Form" with:
1- List Box
1- TextBox
3- Button

I want that it reads all Line of the File and it add an Item in ListBox for line.For example the first Item of the ListBox in this case is
SKI1
And the 2th Item is in this case.
0 1 7
I want using the StreamReader classes.And i want that when i click an Item of the ListBox it shows the Text in the TextBox and I can edit the Line and that clicking antoher button the Item will come updated with new Text of the TextBox.I have also another button for saving the Mod.I can use the AppendText and it create a new file writing ListBox1.Items line for line.
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then Dim file_esistenteD As StreamWriter[code].....
