Using .NET 1.1 Window Forms

I would like to place over 400 pictures on a panel control one after another
one so user can scroll through them, but each picture is up to 200 pixels in
height that''s over 80,000 pixels in total, but panel control can go up to
only 32767 pixels. How can I allow a user to scroll through all of the 400
pictures?
Thanks

推荐答案

怎么说，只是一些图片和一个说更多......的链接。当他们点击它时，你删除现有图片并用原始列表中最后一个后面的

图片刷新它？您甚至可以设置

两个链接Next和上一个。这样看起来会更加用户友好。

How about say, just a few pictures and a link that says "more..." and when
they click it, you delete the existing pictures and refresh it with the
puctures that follow the last one in the original list? You could even set up
two links "Next" and "Previous". Seems like that would be more user-friendly.

感谢您的帮助


这对于网络应用程序来说是一个很好的建议，但是我需要的东西将是/ b
允许用户滚动浏览许多图片。如果我有400张图片

并且用户一次只能在屏幕上看到3或4张图片

想想用户必须点击多少次下一个按钮获得第44张照片的
。

Thanks for your help

This would be good suggestion for a web app, but I need something that will
allow user to scroll through many pictures. If I have 400 hundred pictures
and the user can see only 3 or 4 pictures on the screen at one time just
think how many times the user would have to click on the Next button to get
to the 400th picture.

嗨彼得，


从那以后'是Panel'的高度限制，我建议你每次加载一张

图片，例如点击上一页按钮。按钮或

下一步按钮。


我们可以将所有图片放在一个文件夹中，并使用DirectoryInfo类的

GetFileSystemInfos方法来获取信息

此文件夹中的所有文件，包括这些文件的总数和每个文件的文件名
。然后我们可以轻松地在我们的

计划中浏览所有这些文件。


以下是一个示例。它要求你设置一个Windows

应用程序并将一个PictureBox，两个标签和两个按钮拖放到

表格上。


使用System.IO;


公共类Form1：System.Windows.Forms.Form

{


FileSystemInfo [] infos;

int position = -1;


private void Form1_Load（object sender，System.EventArgs e）

{

DirectoryInfo目录=新的DirectoryInfo（@C：\\\\\\\\\\\\\\\\\\\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

{

infos = dir.GetFileSystemInfos（" * JPG"）;

this.label1.Text = infos.Length.ToString（ ）;

if（infos.Length 0）

{

button2_Click（发件人，e）;

}

}

其他

{

this.label1.Text =" 0";

}

}

//点击button1导航到上一张图片

private void button1_Click（o bject sender，System.EventArgs e）

{

if（position 0）

{

position-- ;

this.pictureBox1.Image = Image.FromFile（infos [position] .FullName）;


}

这个。 label2.Text =（position + 1）.ToString（）;

}

//点击button1导航到下一张图片

private void button2_Click（object sender，System.EventArgs e）

{

if（position< infos.Length - 1）

{

位置++;

this.pictureBox1.Image = Image.FromFile（infos [position] .FullName） ;

}

this.label2.Text =（位置+ 1）.ToString（）;

}

希望这会有所帮助。

Hi Peter,

Since there''s a limitation of Panel''s Height, I recommend you to load a
picture once a time, for example by clicking on a "Previous" button or a
"Next" button.

We could place all the pictures in a folder and make use of the
GetFileSystemInfos method of the DirectoryInfo class to get the information
of all files in this folder, including the total count of these files and
each file''s file name. Then we could navigate among all these files in our
program easily.

The following is a sample. It requires that you have set up a Windows
application and drag&drop a PictureBox, two Labels and two buttons onto the
form.

using System.IO;

public class Form1 : System.Windows.Forms.Form
{

FileSystemInfo[] infos;
int position = -1;

private void Form1_Load(object sender, System.EventArgs e)
{
DirectoryInfo dir = new DirectoryInfo(@"C:\private\others\picures");
if (dir.Exists)
{
infos = dir.GetFileSystemInfos("*JPG");
this.label1.Text = infos.Length.ToString();
if (infos.Length 0)
{
button2_Click(sender, e);
}
}
else
{
this.label1.Text = "0";
}
}
// click on button1 to navigate to the previous picture
private void button1_Click(object sender, System.EventArgs e)
{
if (position 0)
{
position--;
this.pictureBox1.Image = Image.FromFile(infos[position].FullName);

}
this.label2.Text = (position + 1).ToString();
}
// click on button1 to navigate to the next picture
private void button2_Click(object sender, System.EventArgs e)
{
if (position < infos.Length - 1)
{
position++;
this.pictureBox1.Image = Image.FromFile(infos[position].FullName);
}
this.label2.Text = (position + 1).ToString();
}

Hope this helps.
If you don''t think my workaround is suitable to your scenario, please feel
free to let me know.

Linda Liu
