ListView won't show items on x64?

Hi All,

I've found that the ListView control won't display items when my program is
running in x64 mode. I've tried this on both a Pentium D running XP Pro x64
edition and Windows Server 2003 R2 x64 on a Core 2 Duo. Same results on
both.

If I compile for the specific x86 architecture, the problem disappears. In
x64 mode the ListView items are obviously still there because my scroll bars
are there, and if any of them have a background hilite that's visible too -
it's just the text that's disappeared, almost as though it's been painted in
a transparent colour.

Has anybody else had this issue?

Thanks,
Alex Clark

Hi Alex,

I've tried following code on Windows Server 2003 R2 x64 and didn't found
the issue as you described:

using System;
using System.Windows.Forms;

class Class1 : Form
{
    [STAThread]
    static void Main()
    {
        Application.Run(new Class1());
    }

    public Class1()
    {
        ListView listView1 = new ListView();
        listView1.Dock = DockStyle.Fill;
        listView1.View = View.Details;
        listView1.Columns.Add("Column1");
        listView1.Columns.Add("Column2");

        for (int i = 0; i < 1000; i++)
        {
            ListViewItem lvwItem = new ListViewItem("Hello");
            lvwItem.SubItems.Add("World");
            listView1.Items.Add(lvwItem);
        }
        this.Controls.Add(listView1);
    }
}

I compiled it using:

csc.exe /t:winexe /platform:x64 Class1.cs

Would you please try it out and tell me the result? If it's ok on your
side, could you please send me a smaller reproducible project? Thanks.

Hi Walter,

Not to worry, I think I've found this issue - I didn't realise but I was
making some unusual API calls against the ListView in my project which I
suspect I haven't adapted properly to work on x64. The regular ListView
works just fine, which is what I'll "downgrade" to until I've sorted the
issue.

Many thanks,
Alex Clark
