edit

问题 I have a text file that I want to edit by rewriting it to a temp file and then overwrite the original. This code doesn't do that as it's simplified but it does include the problem I have. On Windows the EXAMPLE.TXT file will disappear after a seemly random number of runs when the rename function fails. I don't know why but so far it has worked fine on Linux. Why does this happen and how can I solve it going in an entirety different direction, such as overwriting the original file from within

问题 after days of frustration and getting close to solving the problem, I never really managed to do it. My idea is to edit the color (and other properties) of a specific child int the onChildClick method.

The adapter is so: package org.ksinstitute.arsenieboca; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import android

问题 I am currently in the progress of making a basic PHP app/page, However, I have run into a problem. I have needed to make a script which will edit a variable in another script and set it to something.

问题 So I'm programming a simple calculator in Eclipse for Android 4.0 and I'm trying to stream-line my code and make it as simple as possible. The place I'm trying to clean up is my findViewById()'s. Since I have buttons 0-9 to instantiate I have a block of code ten lines long that look like this: b0 = (Button) findViewById(R.id.b0); b1 = (Button) findViewById(R.id.b1); ... b9 = (Button) findViewById(R.id.b9); As you can see this thing is just begging for a for-loop. So what I wanted to do was

问题 I'm working on a project that entails photographing text (from any hard copy of text) and converting that text into a text file. Then I'd like to use that text file to do some different things, such as provide hyperlinks to news articles or allow the user to edit the document. The tool I've tried so far is Java OCR from sourceforge.net, which works fine on the images provided in the package. But when I photograph my own text, it doesnt work at all. Is there some training process I should be

问题 i'm kinda new in programming so i hope you can help me :) Lately, I've been trying to write sth that can change id3 tags of mp3 file.
