it may affect the functionality of the application to great extent. if the requirement is to wait for around 30 seconds, then by using either of these methods,application will not accept any other event till the control comes out of sleep or while loop. If bFinishDivision And Not bShownDivisionResult ThenĬonsole.WriteLine("Division Result : " & DivisionResult)Ĭonsole.WriteLine("Finished all threads. Get Sleep/Hibernate and Resume/Wakeup events in Visual Basic.NET. The 'sleep API' or the 'while wend' method will put the application in non responding mode. If bFinishSubstration And Not bShownSubstractionResult ThenĬonsole.WriteLine("Substraction Result : " & SubStractResult)
If bFinishAddition And Not bShownAdditionResult ThenĬonsole.WriteLine("Addition Result : " & addResult) Change the size of Form1 to 800,600 in its properties window. First of all, start a new project and name it with any names you like, we are using the name MyWebBrowser.
VISUAL BASIC NET SLEEP HOW TO
In this lesson, we shall learn how to create a simple web browser and get it running in a few minutes. While bFinishAddition = False Or bFinishDivision = False Or bFinishSubstration = False Yes, you can do that in Visual Basic 2019, and pretty easy too.
'Declare the variable for holding the resultĭim bFinishSubstration As Boolean = Falseĭim bShownAdditionResult As Boolean = Falseĭim bShownDivisionResult As Boolean = Falseĭim bShownSubstractionResult As Boolean = FalseĬonsole.WriteLine("Waiting for threads to finish.") Sleep (5000) Be careful when you do this. 'Declare the Thread and assign a sub to thatĭim AddThread As New Threading.Thread(AddressOf AddNumber)ĭim SubstractThread As New Threading.Thread(AddressOf SubstractNumber)ĭim DivideThread As New Threading.Thread(AddressOf DivideNumber) (Classic VBs integer was only 16-bit.) Declare Sub Sleep Lib 'kernel32.dll' (ByVal Milliseconds As Integer) Really though, the managed method isnt difficult. .NET is a developer platform with tools and libraries for building any type of app, including web, mobile, desktop, games, IoT, cloud, and microservices. The AddNumber, SubstractNumber, and DivideNumber functions will be executed by separate threads:Įdit: Now the UI thread waits for the child threads to finish and shows the result. This example uses the Thread Class, but multithreaded applications can also be made using BackgroundWorker.
