How can i set my progressBar value to 0 if its full when i click the button it loads so fast i cant see anything
my code is
private void button1_Click(object sender, EventArgs e)
{
int i;
progressBar1.Minimum = 0;
progressBar1.Maximum = 100;
for (i = 0; i <= 100; i++)
{
progressBar1.Value = i;
if (progressBar1.Value == 100)
{
progressBar1.Value = 0;
}
Refresh();
}
}
Is this what you mean?
private async void button1_Click(object sender, EventArgs e)
{
int i;
progressBar1.Minimum = 0;
progressBar1.Maximum = 100;
for (i = 0; i <= 100; i++)
{
progressBar1.Value = i;
}
await Task.Delay(2000);
if (progressBar1.Value == 100)
{
progressBar1.Value = 0;
}
}
Edit this will now wait 2 seconds until it sets it to empty so you can see that the progress bar does increment to 100.
Your code does exactly what you require.
You may should add a sleep to see something.
private void button1_Click(object sender, EventArgs e)
{
if(IWantToClearTheProgressbarBeforeWork == true)
progressBar1.Value = 0;
int i;
progressBar1.Minimum = 0;
progressBar1.Maximum = 100;
for (i = 0; i <= 100; i++)
{
progressBar1.Value = i;
Thread.Sleep(100); // only for testing. Blocks your thread.
}
if(IWantToClearTheProgressbarImediatelyAfterWorkIsDone == true)
progressBar1.Value = 0;
}

private void _btnOK_Click(object sender, EventArgs e)
{
_label1.Hide();
_label2.Hide();
_label3.Hide();
for(int i = 1; i <= 100; i++)
{
Thread.Sleep(5);
_circularprogressbar.Value = i;
_circularprogressbar.Update();
}
}
private void LoadingScreen_Load(object sender, EventArgs e)
{
_circularprogressbar.Value = 0;
_circularprogressbar.Minimum = 0;
_circularprogressbar.Maximum = 100;
}
}
}
This is my code. What i want to do is, i want to have a text inside the progress bar that shows the percentage of the progress from 1 to 100 percent.
what can i add to my code?
thank you
Here is what i would do:
private void _btnOK_Click(object sender, EventArgs e)
{
_label1.Hide();
_label2.Hide();
_label3.Hide();
for(int i = 1; i <= 100; i++)
{
_circularprogressbar.Value = i;
_percent_lable_name.Text = string.Format("{0}%", _circularprogressbar.Value);
_circularprogressbar.Update();
}
}
private void LoadingScreen_Load(object sender, EventArgs e)
{
_circularprogressbar.Value = 0;
_circularprogressbar.Minimum = 0;
_circularprogressbar.Maximum = 100;
}
}
See if that helps you!
Thanks

That Thread.Sleep(5) is blocking your entire UI thread. If you want to have your UI responsive, while the progress takes place, you need to make a separate thread for it. Something like this:
private void _btnOK_Click(object sender, EventArgs e)
{
_label1.Hide();
_label2.Hide();
_label3.Hide();
Task.Factory.StartNew(() =>
{
for (int i = 1; i <= 100; i++)
{
Thread.Sleep(5);
Invoke((Action)(() =>
{
_circularprogressbar.Value = i;
_circularprogressbar.Update();
}));
}
});
}
Note that you will need t use Invoke to BeginInvoke to access UI components from inside that thread.
Im creating a transition for my form in Visual Studio,
i'm coding a slide effect for the width but it ends up to slow
is there anyway to make it more faster?
btw here is the code :
`int check = 0;
private void button1_Click(object sender, EventArgs e)
{
this.button1.Text = "Hide";
if (check == 0)
{
for (int i = 350; i <= 824; ++i)
{
this.Size = new Size(i, 507);
Thread.Sleep(10);
this.CenterToScreen();
}
check = 1;
}
else if (check == 1)
{
this.button1.Text = "Key";
for (int i = 824; i >= 351; i--)
{
this.Size = new Size(i, 507);
Thread.Sleep(5);
this.CenterToScreen();
}
check = 0;
}
}
By using your existing code, you can tune it for the sake of speed like;
private int check = 0;
private void button1_Click(object sender, EventArgs e)
{
this.button1.Text = "Hide";
if (check == 0)
{
for (int i = 350; i <= 824; i += 2)
{
this.Size = new Size(i, 507);
Thread.Sleep(1);
this.CenterToScreen();
}
check = 1;
}
else if (check == 1)
{
this.button1.Text = "Key";
for (int i = 824; i >= 351; i -= 2)
{
this.Size = new Size(i, 507);
Thread.Sleep(1);
this.CenterToScreen();
}
check = 0;
}
}
You can change Thread.Sleep lines as above and increase or decrease the loop variables for faster an animation.
The problem is the label gets displayed before the progress-bar is completed. How do I make the label display only after the progress-bar is fully complete?
I tried changing the max values to a higher number but it didn't work.
public partial class dload : Form
{
public dload()
{
InitializeComponent();
}
private void dload_Load(object sender, EventArgs e)
{
label1.Visible = false;
}
private void button1_Click(object sender, EventArgs e)
{
int i = 0;
progressBar1.Minimum = 0;
progressBar1.Maximum = 5000;
for (i = 0; i <= 5000; i++)
{
progressBar1.Value = i;
if (i == 5000)
{
label1.Visible = true;
}
}
}
}
Actually, Your code run very vast, it is about less than a second to set value from 0% to 100% ! But
ProgressBar has two styles for displaying the current status (Classic and Continues).
In Continues mode if the progress value went to 100% from 0% the control will show an animation, which is not display the real and accurate progress. You can set a delay via Thread.Sleep() and show your label immediately after the for loop to find out to what i happening !
The Below code will work:
private void button1_Click(object sender, EventArgs e)
{
int i = 0;
progressBar1.Minimum = 0;
progressBar1.Maximum = 5000;
for (i = 0; i <= 5000; i++)
{
Thread.Sleep(1);
progressBar1.Value = i;
}
label1.Visible = true;
}
This is an animation problem. A "hack" around it is to actually decrease the progress value by 1:
progressBar1.Minimum = 0;
progressBar1.Maximum = 5000;
for (int i = 0; i < progressBar1.Maximum; i++) {
progressBar1.Value = i;
progressBar1.Value = Math.Max(i - 1, progressBar1.Minimum);
}
label1.Visible = true;
use progressBar1.Refresh:
public partial class dload : Form
{
public dload()
{
InitializeComponent();
}
private void dload_Load(object sender, EventArgs e)
{
label1.Visible = false;
}
private void button1_Click(object sender, EventArgs e)
{
int i = 0;
progressBar1.Minimum = 0;
progressBar1.Maximum = 5000;
for (i = 0; i <= 5000; i++)
{
progressBar1.Value = i;
progressBar1.Refresh();
if (i == 5000)
{
label1.Visible = true;
}
}
}
I've a project in which i got a listBox1 a timer1 a button1 and a progressBar1.
When i click button1 the timer1 starts.
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
timer1.Interval = 500;
progressBar1.Maximum = listBox1.Items.Count;
progressBar1.Value = 0;
}
When timer1 ticks it removes one item from listBox1 and progressBar1 must show the progress of Removal.
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Enabled = false;
if (listBox1.Items.Count > 0)
{
listBox1.Items.RemoveAt(0);
progressBar1.Increment(1);
groupBox1.Text = listBox1.Items.Count.ToString();
}
if (listBox1.Items.Count > 0)
{
timer1.Enabled = true;
progressBar1.Maximum = listBox1.Items.Count;
progressBar1.Value = 0;
}
}
But i think the above code got some bug with progressBar1 as it dont show progress while removal of items and it is full when the listBox1 items = 0.
There is a better way than this, So set the step property like this in click event :
this.progressBar1.Minimum = 0;
this.progressBar1.Value = 0;
this.progressBar1.Maximum = this.listBox1.Items.Count;
progressBar1.Step = 1;
Now you can do the following:
void timer1_Tick(object sender, EventArgs e)
{
if (listBox1.Items.Count > 0)
{
listBox1.Items.RemoveAt(0);
progressBar1.PerformStep();
groupBox1.Text = listBox1.Items.Count.ToString();
}
else
{
this.timer1.Enabled = false;
}
}
Complete Code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
PopulateList();
}
private void PopulateList()
{
for (int i = 0; i < 10; i++)
{
listBox1.Items.Add(i);
}
}
private void timer1_Tick(object sender, EventArgs e)
{
if (listBox1.Items.Count > 0)
{
listBox1.Items.RemoveAt(0);
progressBar1.PerformStep();
groupBox1.Text = listBox1.Items.Count.ToString();
}
else
{
timer1.Enabled = false;
}
}
private void button1_Click(object sender, EventArgs e)
{
timer1.Tick += timer1_Tick;
timer1.Enabled = true;
timer1.Interval = 500;
progressBar1.Enabled = true;
progressBar1.Visible = true;
progressBar1.Minimum = 0;
progressBar1.Value = 0;
progressBar1.Maximum = listBox1.Items.Count;
progressBar1.Step = 1;
}
}
You are setting progressbar value to 0 after incrementing it...
Try this:
private void timer1_Tick(object sender, EventArgs e)
{
timer1.Enabled = false;
if (listBox1.Items.Count > 0)
{
listBox1.Items.RemoveAt(0);
progressBar1.Increment(1);
groupBox1.Text = listBox1.Items.Count.ToString();
timer1.Enabled = true;
}
}
I have:
private void button1_MouseEnter(object sender, EventArgs e)
{
for (int i = 0; i > 2; i++)
{
button1.Content = Convert.ToString(i);
System.Threading.Thread.Sleep(1000);
}
tekst.Text = "Mouse Enter";
}
When I enter on Button I see only Mouse Enter, but Content on Button don't change. Why? What I can do wrong?
Hi is your for loop correct? It should be i<2 instead of i>2
for (int i = 0; i < 2; i++)
{
Your for loop never execute because you have wrong condition, change it to following code:
for (int i = 0; i < 2; i++)
Also you should use BackgroundWorker (msdn) to update your GUI dynamicly.
private void button1_MouseEnter(object sender, MouseEventArgs e)
{
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += delegate
{
for (int i = 0; i < 2; i++)
{
this.Dispatcher.Invoke((Action)(() => { btn.Content = Convert.ToString(i); }));
System.Threading.Thread.Sleep(1000);
}
};
worker.RunWorkerCompleted += delegate { tekst.Text = "Mouse Enter"; };
worker.RunWorkerAsync();
}
