メインフォーム クラス:

};
this.BeginInvoke(action);
}
void DeleteThreadHandler(String title)
{
Action action = null;
if (title == "beginprogress")
{

{
};
}
else
if (title == "begindelete")
{

{
olvVirtual.BeginUpdate();
};
}

if (title == "enddelete")
{

{
olvVirtual.VirtualListSize = resultList.Count;
olvVirtual.EndUpdate();
RefreshStatus();
progressForm.Close();
if (isError)
errorReportForm.ShowDialog();
};
}
if (title == "progress")
{
action = () =>
{
progressForm.IncProgress(1);
};
}
this.BeginInvoke(action);
}
private void DeleteBtn_Click(object sender, EventArgs e)
{
int checkedcount = GetCheckedCount();
if (checkedcount == 0)
{
MessageBox.Show("Please mark at least a file first");
return;
}
DialogResult dr = new DialogResult();
if (deleteForm == null)
deleteForm = new DeleteForm();
dr = deleteForm.ShowDialog();
if (dr == DialogResult.OK)
{
//if (progressForm == null)
progressForm = new ProgressForm(this);
progressForm.Text = "Deleting...";
progressForm.SetMax(checkedcount);
if (errorReportForm == null)
errorReportForm = new ErrorReportForm();
errorReportForm.ClearMemo();
isError = false;
Thread t = new Thread(DeleteFiles);
t.Start();
progressForm.ShowDialog();
}
}
progressForm には、500 ミリ秒ごとに進行状況を更新するプログレス バーとタイマーがあります。問題は、まだメイン フォームにアクセスできることです。BeginInvoke も試しましたが、どちらも機能しません。
ありがとう
編集:この混乱の原因を見つけました。Microsoft.VisualBasic.FileIO.FileSystem.DeleteFile を使用する DeleteFile です。アンマネージ コードに置き換えた後、正常に動作します。
