我的加载屏幕没有关闭
本文关键字：加载 屏幕 我的 | 更新日期: 2023-09-27 18:33:51
我正在尝试在工作进行时显示一些加载屏幕。我的工作只是一次将一个文件从一个单元格移动到另一个单元格，代码运行良好。但是when i am trying to move a group of files the loading screen is coming and after job its stuck for 20-30 seconds
我找到了解决方案：its because after all the files are moved to the next column, my control is going to dataGridView1_DataBindingComplete 所以发生的事情是网格单元根据我的状况给出颜色当我删除dataGridView1_DataBindingComplete它正常工作时..但是我也需要给颜色......请告诉我如何处理这种情况。
代码：
private void button3_Click(object sender, EventArgs e)
{
Hide();
bool done = false;
ThreadPool.QueueUserWorkItem((x) =>
{
using (var splashForm = new Form4())
{
splashForm.Show();
while (!done)
Application.DoEvents();
splashForm.Close();
}
});
move(); // this is my function to move all files from one column to another
done = true;
Show();
}
private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
string strVal = ini.ReadValue("Action", "Doc-Controller");
bool authenticated = true;
string textboxGroupName1 = ini.ReadValue("Action", "Fabricator");
if (authenticated == UserInCustomRole(textboxGroupName1))
{
foreach (DataGridViewRow row in dataGridView1.Rows)
{
string fName1 = System.IO.Path.GetFileNameWithoutExtension(row.Cells[2].Value.ToString());
string fName2 = System.IO.Path.GetFileNameWithoutExtension(row.Cells[3].Value.ToString());
if (!string.IsNullOrEmpty(fName1) && !string.IsNullOrEmpty(fName2))
{
var f1 = GetValue(fName1.ToCharArray()[fName1.Length - 2]) * 16 + GetValue(fName1.ToCharArray()[fName1.Length - 1]);
var f2 = GetValue(fName2.ToCharArray()[fName2.Length - 2]) * 16 + GetValue(fName2.ToCharArray()[fName2.Length - 1]);
//if (System.IO.Path.GetFileName(fName1) != System.IO.Path.GetFileName(fName2))
if (f1 > f2)
{
//MessageBox.Show(fName1);
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Yellow;
row.Cells[2].Style = style;
}
else if (f2 > f1)
{
//MessageBox.Show(fName1);
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Yellow;
row.Cells[3].Style = style;
}
if (f1 == f2)
{
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Plum;
row.Cells[3].Style = style;
row.Cells[2].Style = style;
}
}
}
}
if (authenticated == UserInCustomRole(strVal))
{
foreach (DataGridViewRow row in dataGridView1.Rows)
{
string fName1 = System.IO.Path.GetFileNameWithoutExtension(row.Cells[3].Value.ToString());
string fName2 = System.IO.Path.GetFileNameWithoutExtension(row.Cells[4].Value.ToString());
if (!string.IsNullOrEmpty(fName1) && !string.IsNullOrEmpty(fName2))
{
var f1 = GetValue(fName1.ToCharArray()[fName1.Length - 2]) * 16 + GetValue(fName1.ToCharArray()[fName1.Length - 1]);
var f2 = GetValue(fName2.ToCharArray()[fName2.Length - 2]) * 16 + GetValue(fName2.ToCharArray()[fName2.Length - 1]);
//if (System.IO.Path.GetFileName(fName1) != System.IO.Path.GetFileName(fName2))
if (f1 > f2)
{
//MessageBox.Show(fName1);
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Yellow;
row.Cells[3].Style = style;
}
else if (f2 > f1)
{
//MessageBox.Show(fName1);
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Yellow;
row.Cells[4].Style = style;
}
if (f1 == f2)
{
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Plum;
row.Cells[4].Style = style;
row.Cells[3].Style = style;
}
}
}
}
}
private int GetValue(char ch)
{
if (ch >= 48 && ch <= 57)
return ch - 48;
else if (ch >= 65 && ch <= 90)
return ch - 65 + 10;
else
return 0;
}
为了帮助您看到大局，这里概述了解决问题的一种方法。 这仅使用一个 BackgroundWorker，请注意，该对话框由主 UI 线程显示，因为它是从 ProgressChanged（） 事件中显示的：
Button Click Handler
Disable the Button
Build a List of the Work to be done
Pass List to RunWorkerAsync
DoWork Handler
Cast e.Argument back to your List
Call ReportProgress() with -1 as the param
Iterate over the List and Do the Work
...after you move each file...
Call ReportProgress() and pass the percentage complete as the first parameter,
with the data to update the grid with in the second parameter
*You can pass anything you want out in the second parameter, like a Custom Class
ProgressChanged Handler
If e.ProgressPercent is -1 Then
Display your Dialog
Else
Cast e.UserState to your progress structure and update the grid accordingly
RunWorkerCompleted Handler
Close your dialog
Re-enable the Button
当他的一个孩子还活着时，你不能关闭线程。对于我们的案例，它是您的 Form4。
尝试将IsBackGround置于真实状态。即使你的一个孩子还活着，它也会让你的线程死亡：
private void button3_Click(object sender, EventArgs e)
{
Thread thd = new Thread(new ThreadStart(SomeThread));
thd.IsBackground = true;
thd.Start();
movement();
dataGridView1.Refresh();
thd.Abort();
}
