code for showing alert in windows forms using C#
Can any one provide code for creating alert for low diskspace using C# in my windows application form.
i have only one drive(say C drive). If available disk space reaches 80%, it should automatically show alert as low disk space.
can you help me i providing sample code.
i have taken button and writen code , but it checks only if press the button.
instead i need automatic alert which can pop up when available disk space reaches 80%.
private void btnSample_Click(object sender, EventArgs e)
{
ArrayList df = new ArrayList();
DriveInfo[] driveListess = DriveInfo.GetDrives();
// Loop through the list of drives
foreach (DriveInfo driven in driveListess)
{
try
{
if (driven.TotalFreeSpace == 0)
{
df.Add(driven.Name.ToString() + ": Disk is full . Please check ");
}
else
{
df.Add(driven.Name.ToString() + " Drive does not have space. Do you wish to delete some of the files? ");
}
}
catch(Exception ex)
{
FreeSpace = 0;
TotalSize = 0;
UsedSpace = 0;
Sweep = 0;
lblFileSystem.Text = "N/A";
lblFreeSpace.Text = "N/A";
lblUsedSpace.Text = "N/A";
lblTotalSize.Text = "N/A";
}
}
string Alertmsg = " " ;
foreach (string str in df)
{
Alertmsg += str + Environment.NewLine;
}
MessageBox.Show(Alertmsg.ToString(),"Alert",MessageBoxButtons.OK,MessageBoxIcon.Warning);
}

Put a timer on the form and set it to execute every few seconds. Call your function from the Elapsed event of the time.
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
Timer timer;
public Form1()
{
InitializeComponent();
timer = new Timer();
timer.Interval = 5000; //every 5 sec for example
timer.Tick += new EventHandler(timer_Tick);
timer.Enabled = true;
}
void timer_Tick(object sender, EventArgs e)
{
//put yor methode here..
}
}
}
But i need code that gives alert automatically when disk space reaches 80%.
in the above code ,i have taken when the disk space is complete.
instead it shouls show alert when disk space reaches 80% of used space

if (driven.TotalFreeSpace < ((double)driven.TotalSize * 0.80d))
{
df.Add(driven.Name.ToString() + ": Disk low free space. " + HumanReadableSize(driven.TotalFreeSpace));
}
public string HumanReadableSize(double len)
{
string[] sizes = { "B", "KB", "MB", "GB" };
int order = 0;
while (len >= 1024 && order + 1 < sizes.Length)
{
order++;
len = len / 1024;
}
string result = String.Format("{0:0.##} {1}", len, sizes[order]);
return result;
}
Cebi - Don't you think the expression should be:
if (driven.TotalFreeSpace < ((double)driven.TotalSize * 0.20d))
sorry :)
100 - 80 = 20%
100 - 80 = 20%
if (driven.TotalFreeSpace < (driven.TotalSize * 0.20d))
{
df.Add(driven.Name.ToString() + ": Disk low free space. " + HumanReadableSize(driven.TotalFreeSpace));
}
The problem here is
in any case it is running only else part
else
{
df.Add(driven.Name.ToStrin
}
even if i take 0.2 or 0.8 it is giving only else part as output
atached is my code in timer1
private void timer1_Tick(object sender, EventArgs e)
{
{
ArrayList df = new ArrayList();
DriveInfo[] driveListess = DriveInfo.GetDrives();
// Loop through the list of drives
foreach (DriveInfo driven in driveListess)
{
try
{
if (driven.TotalFreeSpace < (driven.TotalSize * 0.20d))
{
df.Add(driven.Name.ToStrin
}
else
{
df.Add(driven.Name.ToStrin
}
}
catch (Exception ex)
{
FreeSpace = 0;
TotalSize = 0;
UsedSpace = 0;
Sweep = 0;
lblFileSystem.Text = "N/A";
lblFreeSpace.Text = "N/A";
lblUsedSpace.Text = "N/A";
lblTotalSize.Text = "N/A";
}
}
string Alertmsg = " ";
foreach (string str in df)
{
Alertmsg += str + Environment.NewLine;
}
MessageBox.Show(Alertmsg.T
}
}
