I am trying to press a button that takes the text from textbox4 and textbox5 to write it to a text file. BUT when I press it again to add new info to the text file it just replaces the old text in with the new. How do I get it to write another line below the first one each time I press the button? This is the code I have so far private void button5_Click(object sender, EventArgs e) { try { xuidspath = @"c:\xuids.txt"; ListViewItem lvi = new ListViewItem(); lvi.Text = textBox4.Text; lvi.SubItems.Add(textBox5.Text); listXuid.Items.Add(lvi); TextWriter xuids = new StreamWriter(xuidspath); xuids

I'm developing a text editor in C#, and I'm trying to make a line count. private void updateNumberLabel() { Point pos = new Point(0, 0); int firstIndex = Document.GetCharIndexFromPosition(pos); int firstLine = Document.GetLineFromCharIndex(firstIndex); pos.X = ClientRectangle.Width; pos.Y = ClientRectangle.Height; int lastIndex = Document.GetCharIndexFromPosition(pos); int lastLine = Document.GetLineFromCharIndex(lastIndex); int actualLine = Document.GetLineFromCharIndex(actualPos); pos = Document.GetPositionFromCharIndex(lastIndex); if (lastLine != actualLine) { numberLabel.Text = ""; for

I have a tetrahedron object created in openGL ES 2.0. What I'm trying to achieve is to show the actual wireframe of the polygon over its base color. Is there a method for achieving this effect? Also, my tetrahedron is pink. How can I change its color? In addition to what Jave said. Instead of enlarging the whole object (whose optimal amount always depends on the object and the current view) to prevent z-fighting artefacts, you can also use the polygon offset (using glPolygonOffset ), whose major application are indeed wireframe overlays. It basically works by slightly adjusting the depth

I find many ways to do this, AWK , SED , UNIQ , but none of them are working on my file. I want to delete duplicate lines. Here is an example of part of my file: KTBX KFSO KCLK KTBX KFSO KCLK PAJZ PAJZ NOTE: I had to manually add line feeds when I cut and pasted from the file...for some reason it was putting all the variables on one line. Makes me think that my 44,000 line text file actually has only "1" line? Is there a way to modify it so I can delete dups? philshem You can see all non-printed characters with this command: od -c oldfile If all your records are on one line, you can use sed to

I would be realy gratefully if some python ninja could fix this.(or in bash?) Well, since OP is learning python .
