VB.Net

Question

Hi I have one function called getreport() and one button called btnGenerateReport my code is - Protected Sub btnGenerateReport_Click(ByVal sender As Object ByVal e As System.EventArgs) Handles btnGenerateReport.Click getreport() End Sub as soon as i click on button i want to get time before loading data from this function and after loading data from this function. So that i can get that how much time this function is taking to load data. Help.

You appear to be missing a call to the getreport() method in your code behind: btnGenerateReport.Enabled = false Dim sw1 As Stopwatch = Stopwatch.StartNew() getreport() sw1.Stop() Dim ts1 As TimeSpan = sw1.Elapsed Label1.Text = ts1.TotalMilliseconds.ToString() +  ms for show btnGenerateReport.Enabled = true The idea of the stopwatch is that it starts at 0 just before you call getreport() and when getreport returns (i.e. the data has loaded) it's stopped and the time that has elapsed is read off and printed to the label. It might be a good idea to disable the button while this measurement is taking place and I've added some lines above to do this:

Thanks I got this but i want to check time difference between before and after loading data. Means when i click on button then i should get time and after loading data also i should get time so that i can get that how much time it took to load data. and one more thing - i have created a button ans a label just for test time- code behind - Dim sw1 As Stopwatch = Stopwatch.StartNew() sw1.Stop() Dim ts1 As TimeSpan = sw1.Elapsed Label1.Text = ts1.TotalMilliseconds.ToString() +  ms for show now if i click on button i am getting 0 ms in label and if i click again on same button i am getting 0.003 ms in label so i am not able to get exact time. Please help

Hi  You can use like this System.Diagnostics.Stopwatch

Vulpes · Answer

Sorry the syntax of that line isn't quite right it should be: Dim sw As StopWatch = StopWatch.StartNew()

As well as importing the System.Diagnostics namespace you'll also need to add a reference to System.dll to your project unless it's been added already.

Hi But in this line - Dim sw As StopWatch.StartNew() StopWatch i am not getting.

Vulpes · Answer

I'd use the System.Diagnostics.StopWatch class for this: Imports System.Diagnostics ' .... Dim sw As StopWatch.StartNew() getreport() sw.Stop() Dim ts As TimeSpan = sw.Elapsed Label1.Text = ts.TotalMilliseconds.ToString() +  ms;
