在运行时将值发送到文本框

Question

I am running a console application. I am having a textbox in a form. I need to calculate number of messages read in last five minutes in another class and display the value in textbox. When I run the code I can able to see the textbox.text value correctly. But in UI I can't see the value is displayed in the textbox. But I can able to edit the textbox manually during runtime.

Here is my code:

In codebehind

for (int i = 1; i <= numberOfMsgs; i++)
{
    if (addDateTime.AddMinutes(2).Minute==DateTime.Now.Minute)
    {
        //FilesProcessedInFiveMinutes();
        //Thread thread1 = new Thread(new ThreadStart(FiveMinutesMessage));
        //thread1.Start();
        WebSphereUI webSphereUi = new WebSphereUI();
        webSphereUi.count(fiveMinutesCount);
        addDateTime = DateTime.Now;
    }
    fiveMinutesCount = fiveMinutesCount + 1;
}

In form.cs

public void count(int countValue)
{
    Thread.Sleep(2000);
    txtLastFiveMins.Focus();
    txtLastFiveMins.Text = countValue.ToString();
    txtLastFiveMins.Refresh();
    txtLastFiveMins.Show();
    backgroundWorker1.RunWorkerAsync(2000);
}

It looks like you are creating a new form every time you enter the if statement. This line is creating a new WebSphereUI form:

    WebSphereUI webSphereUi = new WebSphereUI();

Then, you call the count method on it:

    webSphereUi.count(fiveMinutesCount);

But then you you continue on, without showing this form. If you add:

    webSphereUi.Show();

Then you might see the form appear on the screen, displaying the value as expected. However, this is going to show a new form every time the if statement is executed. You could reuse the same form by declaring it elsewhere, and using it in the loop:

class yourClass
{

    WebSphereUI webSphereUi = new WebSphereUI();

    ...

    private void yourFunction()
    {
        for (int i = 1; i <= numberOfMsgs; i++)
        {
            if (addDateTime.AddMinutes(2).Minute==DateTime.Now.Minute)
            {
                webSphereUi.count(fiveMinutesCount);
                webSphereUi.Show();
                addDateTime = DateTime.Now;
            }
            fiveMinutesCount = fiveMinutesCount + 1;
        }
    }

}
