  • How to edit item in a listbox shown from reading a .csv file?

    - by Shuvo
    I am working in a project where my application can open a .csv file and read data from it. The .csv file contains the latitude, longitude of places. The application reads data from the file shows it in a static map and display icon on the right places. The application can open multiple file at a time and it opens with a new tab every time. But I am having trouble in couple of cases When I am trying to add a new point to the .csv file opened. I am able to write new point on the same file instead adding a new point data to the existing its replacing others and writing the new point only. I cannot use selectedIndexChange event to perform edit option on the listbox and then save the file. Any direction would be great. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms;

  • How would I set up this enum to return the image I want?

    - by Justen
    I'm trying to set up this enum so that it has the ability to return the correct image, though I'm struggling with a way to incorporate the context since it is in a separate class. public enum CubeType { GREEN { public Drawable getImage() { return Context.getResources().getDrawable( R.drawable.cube_green ); } }; abstract public Drawable getImage(); } The error I'm getting is: Cannot make a static reference to the non-static method getResources() from the type Context

  • 2D distortion of a face from an image on iOS? (similar to Fat Booth etc.)

    - by Dominik Hadl
    I was just wondering if someone knows about some good library or tutorial on how to achieve a 2D distortion of a face taken from an image taken by the user. I would like to achieve a similar effect to the one in Fatify, Oldify, all those Fat Booths, etc., because I am creating an app where you will throw something at the face and I would the face to jiggle and move when the object hits it. How should I do this?

  • Grid overlayed on image using javascript, need help getting grid coordinates.

    - by Alos
    Hi I am fairly new to javascript and could use some help, I am trying to overlay a grid on top of an image and then be able to have the user click on the grid and get the grid coordinate from the box that the user clicked.

  • Changing background image of a Drupal page based on user's selection...?

    - by Sambo
    Hi I'm trying to give my users the functionality to change what the background image used on a page is. The list of background images will be a small number that won't really change. I thought I could add a few Taxonomy terms...one for each background type...then apply a class to the body tag when the page is viewed. Does this sound feasible and if so how would I go about doing it? Thanks Sam

  • Can I run a 64-bit VMWare image on a 32-bit machine?

    - by John Sibly
    Can I run a 64-bit VMWare image on a 32-bit machine? I've Googled this but there doesn't seem to be a conclusive answer. I know that it would have to be completely emulated and would run like a dog - but slow performance isn't necessarily an issue as I'm just interested in testing some of my background services code on 64-bit platforms.
