帮助将png文件添加到列表视图框中 [英] help adding a png file to a listview box

问题描述

我有以下代码，其中我连接到远程计算机以获取已安装软件的列表.该代码工作正常，但非常空白，我想通过在特定名称旁边添加一个png图标来为其增添趣味.现在我已经通过删除我想要链接到特殊图标的代码在底部用空的if语句测试了代码，只是不知道如何在StrName旁边添加png图标.

我尝试添加ListView1.Items(0).ImageIndex = 1，但这对我没有用.

如果有人可以帮助，那将是很好.我整天都在看这本书，我认为我需要其他人的注意.

I have the below code where i m connecting to a remote computer to get a list of installed software. The code works fine but its very blan and i want to spice it up with adding a png icon next to specific names. Now i have tested the code with the empty if statement at the bottom by deleting the ones i want to have a special icon linked to i just dont know how i would add a png icon next to StrName.

I have tried adding ListView1.Items(0).ImageIndex = 1 but this didnt work for me.

If someone could help that would be great. I have been looking at this all day and i think i need someone else eyes on it.

推荐答案

在WinForm中，您需要从ListBox继承一个新控件.在您的解决方案中创建一个类型为"Windows控制库"的新项目.这是代码文件:

In WinForm, you need to inherit a new control from ListBox. Create a new project in your solution, of the type "Windows Control Library". Here is the code file:

public partial class ListBoxWithBg : ListBox 
{ 
 Image image; 
 Brush brush, selectedBrush; 

 public ListBoxWithBg(String ImageFile) 
 { 
   InitializeComponent(); 
   this.DrawMode = DrawMode.OwnerDrawVariable; 
   this.DrawItem += new DrawItemEventHandler(ListBoxWithBg_DrawItem); 
   this.image = Image.FromFile(ImageFile); 
   this.brush = new SolidBrush(Color.Black); 
   this.selectedBrush = new SolidBrush(Color.White); 
 }
}
